DESCRIPTION/BACKGROUND The international building codes (I-Codes) are developed by construction industry professionals and adopted around the United States as model codes based on the best, most recent building science. The I-Codes form a framework upon which the County develops a building code with local amendments reflecting the County’s unique needs as determined by local code users. The county’s codes are reviewed by a community Code Review Committee, the Building Board of Appeals and Planning Commission, and ultimately approved by the Larimer County Board of County Commissioners. Updated I-Codes are published every three years by the International Code Council, Inc. (ICC), headquartered in Washington D.C. with regional offices in Birmingham, Alabama, Whittier, California and Chicago, Illinois. ICC was created in 1994 when three separate model building code groups from the Southern, Eastern and Western parts of the United States merged. These organizations and their model codes have roots going back to early 20th century America. Larimer County, along with most other local jurisdictions, has adopted updated codes approximately every three years since 1972. The 2009 edition of the I-Codes was adopted by Larimer County in June 2011, effective July 31, 2011. Adoption of the most recent 2012 code editions with amendments is in the best interest of the people of Larimer County and will promote their health, safety and welfare. Adoption of up-to-date I-Codes also benefits the County and citizens by: •

Establishing consistency of code adoptions with other local jurisdictions.

BCC 10/14/13

2012 INTERNATIONAL BLDG CODE

•

Ensuring a high County rating by the Insurance Services Organization (ISO). ISO collects information nation-wide on building codes in effect in communities, as well as how the communities enforce their building codes. ISO analyzes the data using a Building Code Effectiveness Grading Schedule and assigns a grade to each community. Insurers can use the grade to grant premium credits for buildings constructed under strictly enforced codes. Larimer County was most recently audited in 2011 by ISO and received a grade of 3 on a scale of 1 to 10, 1 being the highest rating. The single most important weighting factor used by ISO is how up-to-date a jurisdiction’s adopted codes are. We had originally been graded a 5 for residential and a 4 for commercial, because we had yet adopted the 2009 International Codes.

•

Maintaining eligibility for FEMA and other grants (i.e., FEMA has the option of rejecting grant requests if recent code editions are not adopted by the requesting jurisdiction).

We are proposing the adoption of the 2012 I-Codes to go into effect January 1, 2014, approximately six weeks after the scheduled hearing before the Board of County Commissioners, to give engineers, architects, homeowners and builders time to adjust to the new codes. The City of Fort Collins is undergoing a parallel code review/update process, and proposes to have their 2012 codes go into effect on or about the same date. The City of Loveland has already adopted the 2012 codes, effective June 28, 2013. Other nearby jurisdictions are either adopting or have already adopted the 2012 codes. The Larimer County Building Department formed a 2012 I-Code review committee consisting of county staff, architects and builders from across the county. Community members were Michael Doddridge of Doddridge Construction/Northern Colorado Homebuilders Association, Alan Hauser of Hauser Architects, and Steve Lane of Basis Architecture. Committee members reviewed existing 2009 I-Code amendments and significant changes from the 2009 to the 2012 I-Codes, and came to unanimous agreements on proposed 2012 amendments. The proposed amendments were reviewed by the Building Board of Appeals (BBOA), which recommended their approval (letter attached). When these amendments were presented to a joint work session of the Larimer County Planning Commission and Board of County Commissioners, a request was made for cost estimates of individual code changes and the entire updated code. An internet search including the Home Builders Association and ICC does not turn up any such comprehensive cost analysis. As the code changes each cycle run into the hundreds, it is not possible for the county building department to produce such a report. An attempt has been made to provide a cost analysis of some of the most significant changes. Much of the discussion surrounding the 2012 I-codes centers on the changes to the International Energy Conservation Code (IECC), whose residential portion is incorporated into the 2012 International Residential Code. The IECC requires tighter building envelopes, more insulation in wall and ceiling cavities, better performing windows, insulation on domestic hot water piping, a blower door test to determine air leakage rates, more efficient lighting, and sets minimum fan efficiency standards for whole house mechanical ventilation.

BCC 10/14/13

2012 INTERNATIONAL BLDG CODE

In their “2012 IECC Cost Effectiveness Analysis,” the National Association of Home Builders Research Center weighed the cost of the new rules versus the expected energy cost savings, and calculated the payback period. They concluded the 2012 changes will increase the cost of the average home in our climate zone by $4,653, with a payback period of 9.2 years. The same analysis performed by the Building Codes Assistance Project concluded the added cost to a new home (same size and climate zone) would be $1,412, with a payback period of 17 months. Some of the highest incremental costs arise from increasing prescriptive basement/crawl space wall and ceiling insulation requirements, which accounts for about half the projected increase. The proposed county code amendments keep these requirements at current levels. The Code Review Committee felt the “biggest bang for the buck” came from increased attention to air sealing the building envelope, so conditioned air is not lost to building cavities and the exterior. Since builders will know a successful blower door test (showing less than 3 air changes per hour) will be required to pass final inspection – a requirement already in place in Fort Collins and Loveland – they will pay more attention during construction to building a tighter house that will be more comfortable, more energy efficient, and save the owner money on fuel bills. The blower door test itself is estimated to cost about $350 and the whole house mechanical ventilation system (a combination of outdoor air intake and exhaust fans) approximately $300. On September 18, 2013, the Larimer County Planning Commission considered the proposed 2012 codes, and voted 7-0 to recommend their adoption as amended to the Board of County Commissioners. SIGNIFICANT CODE CHANGES: Other significant code changes include: • A proposed local amendment to delete the section of the code that requires new one- and twofamily dwellings to have fire-sprinklers. Many jurisdictions are removing this requirement, which could add $5,000 or more to the cost of a new home. • A proposed local amendment to delete the section of the code requiring gypsum protection on the underside of I-joists in basements and crawl spaces. This could cost $1,000 in new homes. • A proposed local amendment to clarify dates for Temporary Certificates of Occupancy. • Raising the height of fences exempt from permit requirements from 6’ to 7’. For consistency, a local amendment proposes to keep the current code limit but apply the rules flexibly. • A drip edge is now required at eaves and gables of shingle roofs. • Plastic drain-waste-vent pipe can only be tested by water, not air. A local amendment proposes to delete this requirement, which would cause practical difficulties with no known local benefit. • A new section detailing rules for installing photovoltaic systems, which are rapidly increasing. • Reinstating an amendment requiring spark arrestors for woodstoves in the wildfire hazard area. • Carbon monoxide detectors are required for construction under the International Building Code in occupancy groups R and I with fuel burning appliances or attached garages. • Floor-level exit signs are required in Group R-1 Occupancies (hotels/motels) where general-use exit signs are required. This requirement was in the old Uniform Building Code. • Clarifications to our prescriptive rules for construction in High-Wind Areas, based on evolving engineering standards. Building codes generally require engineered plans in areas with design wind speeds over 110 miles per hour, which includes most of Larimer County. To save homeowners that expense while maintaining public safety, the county has developed and maintains a set of prescriptive rules for high-wind areas, incorporated into the building code.

2012 INTERNATIONAL BLDG CODE

CLARIFICATIONS TO BUILDING PERMIT FEE TABLE: In addition, the Building Department is recommending clarification to our Building Permit Fee Schedule, Tables 1-A and 1-B, to make the fee structure more transparent. The Building Department has been for many years assessing a one-time “mountain area fee” of $50 to offset the increased costs to perform inspections in remote parts of the county. This fee is not currently listed in the published table. The Building Department has also historically assessed an “investigation fee” for work started without a required building permit. Building codes up through the 1997 Uniform Building Code required an investigation fee “equal to the permit fee” in such cases. That wording was left out of the 2003 I-Codes adopted by Larimer County in 2004. The 2012 I-Codes state that persons commencing work without a required permit “shall be subject to a fee established by the applicable governing authority that shall be in addition to the required permit fees.” Since the code language has changed, the fee must be specified in the adopted fee table. Per a suggestion from the Planning Commission, we propose to rename the investigation fee as a “penalty fee” and to assess an amount “up to or equal to the building permit fee.” Miscellaneous plumbing and mechanical permits are assessed a minimum fee no matter the valuation of the work, but a minimum fee for residential, commercial and utility construction has not been established. At present, the lowest permit price for residential or commercial construction valued up to $500 is $22.24, which does not cover the minimum costs to initiate, review and issue a permit, perform required inspection(s) and finalize the permit. Since a minimum fee is assessed for both plan review and inspections, the Building Official proposes to establish a minimum fee of $43.00 for all permits. NOTICE OF HEARING: Notice of the public hearing has been posted in local newspapers and on the county website. The Building Department will hold classes, send out e-mails, post the information on our website, and otherwise communicate as widely as possible the upcoming changes to inform interested parties. STAFF RECOMMENDATIONS: 1. The Larimer County Board of County Commissioners adopt the 2012 International Residential Code, 2012 International Building Code, 2012 International Plumbing Code, 2012 International Mechanical Code, 2012 International Fuel Gas Code, 2012 International Energy Conservation Code, 2012 International Existing Building Code, and the 1997 Uniform Code for the Abatement of Dangerous Buildings, with proposed amendments, all to be effective January 1, 2014. 2. The Larimer County Board of County Commissioners repeal the currently adopted 2009 International Residential Code, 2009 International Building Code, 2009 International Plumbing Code, 2009 International Mechanical Code, 2009 International Fuel Gas Code, 2009 International Energy Conservation Code, 2009 International Existing Building Code and proposed amendments, all to be effective January 1, 2014. 3. The Larimer County Board of County Commissioners amend the Building Permit Fee Schedule Tables 1-A and 1-B, effective January 1, 2014.

For applications for reconstruction, rehabilitation, addition, or other improvement of existing buildings or structures located in an area prone

BCC 10/14/13

2012 INTERNATIONAL BLDG CODE

to flooding as established by Table R301.2(1), the county engineer shall examine or cause to be examined the construction documents and shall prepare a finding with regard to the value of the proposed work. For buildings that have sustained damage of any origin, the value of the proposed work shall include the cost to repair the building or structure to its pre-damage condition. If the county engineer finds that the value of proposed work equals or exceeds 50 percent of the market value of the building or structure before the damage has occurred or the improvement is started, the finding shall be provided to the Floodplain Review Board for a determination of substantial improvement or substantial damage. Applications determined by the Floodplain Review Board to constitute substantial improvement or substantial damage shall meet the requirements of Section R322. The following section is hereby amended to read as follows: R105.5 Expiration. Every permit issued by the building official under the provisions of this code shall expire 18 months after the date of issue. The building official is authorized to grant a onetime written extension of 18 months at no charge making the original permit valid for three years. Additional 18 month extensions will cost one-half the amount of the original building permit fee. Every permit shall also become invalid if the building or work authorized by such permit is not commenced within 180 days from the date of issue of such permit or if the person or entity to whom the permit is issued fails to request a first inspection within 180 days of the date of such permit. Before such work can be recommenced, a new permit shall be first obtained to do so. The fee for such new permit shall be one-half of the original building permit fee, provided no changes have been made or will be made in the original plans and specifications for such work. Changes in the plans and specifications shall require an additional permit fee and plan review fee as described in Section R108. The following section is hereby amended to read as follows: R106.1.3 Information for construction in flood hazard areas. For buildings and structures located in whole or in part in flood hazard areas as established by Table R301.2(1), construction documents shall include: 1. Delineation of flood hazard areas, floodway boundaries and flood zones and the design flood elevation, as appropriate; 2. The elevation of the proposed lowest floor, including basement; in areas of shallow flooding (AO zones), the height of the proposed lowest floor, including basement, above the highest adjacent grade; and 3. If design flood elevations are not included on the county’s Flood Insurance Rate Map (FIRM), the county engineer and the applicant shall obtain and reasonably utilize any design flood elevation and floodway data available from other sources. The following section is hereby amended to read as follows: R107.1 General. The building official is authorized to issue a permit for temporary structures and temporary uses. Such permits shall be limited as to time of service, but shall not be permitted for more than 18 months. The building official is authorized to grant extensions for demonstrated cause. The following section is hereby amended to read as follows: R107.3 Temporary power. The Colorado State Electrical Board is authorized to give permission to temporarily supply and use power in part of an electrical installation before such installation has been fully completed and the final certificate of completion has been issued. The part covered by the temporary certificate shall comply with the requirements specified for temporary lighting, heat or power in the most recently adopted National Electrical Code. The following section is hereby added to read as follows: R108.7 Expiration of Plan Review. Applications for which no permit is issued within one hundred and eighty (180) days following the date of application shall expire by limitation, and plans submitted for review may thereafter be returned to the applicant or destroyed by the building official. The building official may extend the time for action by the applicant for a period not exceeding ninety (90) days upon written request by the applicant showing that circumstances beyond the control of the applicant have prevented action from being taken. In order to renew action on an application after expiration, the applicant shall resubmit plans and pay a new plan review fee. The following section is hereby added to read as follows: R108.8 Re-inspections. A re-inspection fee as set forth in an adopted fee schedule may be assessed for each inspection or reinspection when such portion of work for which inspection is called for is not complete or when corrections called for are not made. This section is not to be interpreted as requiring re-inspection fees the first time a job is rejected for failure to comply with the requirements of this Code, but as controlling the practice of calling inspections before the job is ready for such inspection or reinspection. Re-inspection fees may be assessed when the inspection record card is not posted or otherwise available on the work site, the approved plans are not readily available to the inspector, for failure to provide access on the date for which inspection is requested, for deviating from plans requiring the approval of the building official, or for failure to post a readily visible address as required by section R319. To obtain a re-inspection, the applicant shall pay the re-inspection fee in accordance with the fee schedule. In instances where re-inspection fees have been assessed, no additional inspection of the work will be performed until the required fees have been paid. The following section is hereby amended to read as follows: R108.9 Temporary Certificate of Occupancy. There will be a $600 fee for a Temporary Certificate of Occupancy. A Temporary Certificate of Occupancy shall be valid for 180 days. If a full Certificate of Occupancy is issued within the first 30 days, all but $40 will be refunded. If a full Certificate of Occupancy is issued prior to the 180 day expiration, $100 shall be refunded for each 30 day period remaining out of the original 180 day validity period of the Temporary Certificate of Occupancy. The following section is hereby amended to read as follows: R110.1 Use and occupancy. No building or structure shall be used or occupied, and no change in the existing occupancy classification of a building or structure or portion thereof shall be made until the building official has issued a certificate of occupancy therefore as provided herein. Issuance of a certificate of occupancy shall not be construed as an approval of a violation of the

BCC 10/14/13

2012 INTERNATIONAL BLDG CODE

provisions of this code or of other county ordinances. Certificates presuming to give authority to violate or cancel the provisions of this code or other county ordinances shall not be valid. Exceptions: 1. Certificates of occupancy are not required for work exempt from permits under Section R105.2. 2. Shell, agriculture, accessory buildings and miscellaneous permits shall not receive certificates of occupancy; a letter of completion will be given upon request. The following section is hereby amended to read as follows: R112.2.1 Determination of substantial improvement in areas in flood hazard areas. When the county engineer provides a finding required in Section R105.3.1.1, the Floodplain Review Board shall determine whether the value of the proposed work constitutes a substantial improvement. The following section is hereby amended to read as follows: R112.3 Qualifications The board of appeals shall consist of members who are qualified by experience and training to pass on matters pertaining to building construction and are not employees of the Community Development Division. The following section is hereby amended to read as follows: R112.4 Administration. Persons desiring to appeal a decision of the building official to the Board of Appeals shall, at the time of making such appeal, pay to the Larimer County Building Department a docket fee as specified in the Larimer County fee schedule. Written notice of hearing shall be given to all parties concerned at least fourteen (14) days prior to the hearing by e-mail or by mailing the same to such parties' last known address by regular mail. The Board shall periodically adopt such additional rules and regulations as it deems necessary and advisable for the conduct of its hearings and for carrying out the provisions thereof. The building official shall take immediate action in accordance with the decision of the board. All meetings or hearings shall be open to the public.

The purpose of this chapter is to establish minimum standards for design and construction of new buildings or portions thereof for the protection of life and property from wildfire. 3601.1 Scope. Within the wildfire hazard area, as defined by the Wildfire Hazard Area Map and foot note #3 of amended Table 1505.1, all new building construction and all additions equal to or greater than 50% of the total square footage of the original structure shall comply with the provisions of this chapter. New building construction shall include all new structures. EXCEPTIONS: Loafing sheds and similar structures. 3601.2 Alternate Materials and Methods of Compliance. The provisions of this chapter are not intended to prevent the use of any material or method of compliance not specifically prescribed by this chapter, provided any alternate has been approved and its use authorized by the building official. The building official may approve any such alternate, provided it is found that the proposed design is satisfactory and complies with the provisions of this chapter and this code and that the material method or work offered is, for the purpose intended, at least the equivalent of that prescribed in this chapter in suitability, effectiveness, fire resistance, durability and safety. The building official shall require that sufficient evidence or proof be submitted to substantiate any claims that may be used regarding use of the alternate. The details of any action granting approval of an alternate shall be recorded and entered in the files of the Building Department. 3602.0 Definitions. For the purpose of this chapter, certain terms are defined as follows: Combustible - a material that fails to meet the acceptance criteria of Standard Method of test for determination of noncombustibility in building materials. Combustible construction - a type of construction that does not meet the requirement for noncombustible construction. Defensible space - a natural or man-made area, where woody vegetation capable of allowing a fire to spread unchecked has been treated or modified to slow the spread and reduce the intensity of an advancing wildfire, and to create an area for fire suppression operations to occur. Fire-resistive construction - construction designed to resist the spread of fire. Fire-resistive rating - the time that the material or construction will withstand the standard fire exposure as determined by a fire test made in conformity with the standard methods of fire tests of buildings construction and materials. Fire-retardant-treated wood - any wood product impregnated with chemicals by a pressure process or other means during manufacture, and which shall have a flame-spread index of not over 25. Fire separation - a construction assembly that acts as a barrier against the spread of fire. Firewall Assembly- a type of fire separation of noncombustible construction which subdivides a building or separates adjoining buildings to resist the spread of fire and which has a fire-resistance rating and structural ability to remain intact under conditions for the required fire-rated time.

BCC 10/14/13

2012 INTERNATIONAL 12 BLDG CODE

Flame-resistant material - material that has been modified in its chemical composition by impregnation, coating or has inherent composition that makes the material resistant to ignition and combustion when exposed to a small ignition source. Flame retardant - an approved chemical compound or mixture which, when applied in an approved manner to any fabric or other material will render such fabric or material incapable of supporting combustion. Flame-spread index (FSI) - a relative index describing the surface-burning characteristics of building materials. The test used to establish FSI evaluates the flame spread over the building material surface when exposed to a test fire. The rate at which flame spreads across the specimen is compared on a scale of 0 for inorganic reinforced cement board, to 100 for red oak." The following table identifies the flame-spread index and Flame Spread Classification:

Flame Spread Classification

Flame Spread Index

Class I

0 to 25

Class II

___________________________________________________________________________________ DESCRIPTION/BACKGROUND The international building codes (I-Codes) are developed by construction industry professionals and adopted around the United States as model codes based on the best, most recent building science. The I-Codes form a framework upon which the County develops a building code with local amendments reflecting the County’s unique needs as determined by local code users. The county’s codes are reviewed by a community Code Review Committee, the Building Board of Appeals and Planning Commission, and ultimately approved by the Larimer County Board of County Commissioners. Updated I-Codes are published every three years by the International Code Council, Inc. (ICC), headquartered in Washington D.C. with regional offices in Birmingham, Alabama, Whittier, California and Chicago, Illinois. ICC was created in 1994 when three separate model building code groups from the Southern, Eastern and Western parts of the United States merged. These organizations and their model codes have roots going back to early 20th century America. Larimer County, along with most other local jurisdictions, has adopted updated codes approximately every three years since 1972. The 2009 edition of the I-Codes was adopted by Larimer County in June 2011, effective July 31, 2011.

2012 INTERNATIONAL BLDG CODE

Adoption of the most recent 2012 code editions with amendments is in the best interest of the people of Larimer County and will promote their health, safety and welfare. Adoption of up-to-date I-Codes also benefits the County and citizens by: •

Establishing consistency of code adoptions with other local jurisdictions.

•

Ensuring a high County rating by the Insurance Services Organization (ISO). ISO collects information nation-wide on building codes in effect in communities, as well as how the communities enforce their building codes. ISO analyzes the data using a Building Code Effectiveness Grading Schedule and assigns a grade to each community. Insurers can use the grade to grant premium credits for buildings constructed under strictly enforced codes. Larimer County was most recently audited in 2011 by ISO and received a grade of 3 on a scale of 1 to 10, 1 being the highest rating. The single most important weighting factor used by ISO is how up-to-date a jurisdiction’s adopted codes are. We had originally been graded a 5 for residential and a 4 for commercial, because we had yet adopted the 2009 International Codes.

•

Maintaining eligibility for FEMA and other grants (i.e., FEMA has the option of rejecting grant requests if recent code editions are not adopted by the requesting jurisdiction).

We are proposing the adoption of the 2012 I-Codes to go into effect January 1, 2014, approximately six weeks after the scheduled hearing before the Board of County Commissioners, to give engineers, architects, homeowners and builders time to adjust to the new codes. The City of Fort Collins is undergoing a parallel code review/update process, and proposes to have their 2012 codes go into effect on or about the same date. The City of Loveland has already adopted the 2012 codes, effective June 28, 2013. Other nearby jurisdictions are either adopting or have already adopted the 2012 codes. The Larimer County Building Department formed a 2012 I-Code review committee consisting of county staff, architects and builders from across the county. Community members were Michael Doddridge of Doddridge Construction/Northern Colorado Homebuilders Association, Alan Hauser of Hauser Architects, and Steve Lane of Basis Architecture. Committee members reviewed existing 2009 I-Code amendments and significant changes from the 2009 to the 2012 I-Codes, and came to unanimous agreements on proposed 2012 amendments. The proposed amendments were reviewed by the Building Board of Appeals (BBOA), which recommended their approval (letter attached). When these amendments were presented to a joint work session of the Larimer County Planning Commission and Board of County Commissioners, a request was made for cost estimates of individual code changes and the entire updated code. An internet search including the Home Builders Association and ICC does not turn up any such comprehensive cost analysis. As the code changes each cycle run into the hundreds, it is not possible for the county building department to produce such a report. An attempt has been made to provide a cost analysis of some of the most significant changes.

2012 INTERNATIONAL BLDG CODE

Much of the discussion surrounding the 2012 I-codes centers on the changes to the International Energy Conservation Code (IECC), whose residential portion is incorporated into the 2012 International Residential Code. The IECC requires tighter building envelopes, more insulation in wall and ceiling cavities, better performing windows, insulation on domestic hot water piping, a blower door test to determine air leakage rates, more efficient lighting, and sets minimum fan efficiency standards for whole house mechanical ventilation. In their “2012 IECC Cost Effectiveness Analysis,” the National Association of Home Builders Research Center weighed the cost of the new rules versus the expected energy cost savings, and calculated the payback period. They concluded the 2012 changes will increase the cost of the average home in our climate zone by $4,653, with a payback period of 9.2 years. The same analysis performed by the Building Codes Assistance Project concluded the added cost to a new home (same size and climate zone) would be $1,412, with a payback period of 17 months. Some of the highest incremental costs arise from increasing prescriptive basement/crawl space wall and ceiling insulation requirements, which accounts for about half the projected increase. The proposed county code amendments keep these requirements at current levels. The Code Review Committee felt the “biggest bang for the buck” came from increased attention to air sealing the building envelope, so conditioned air is not lost to building cavities and the exterior. Since builders will know a successful blower door test (showing less than 3 air changes per hour) will be required to pass final inspection – a requirement already in place in Fort Collins and Loveland – they will pay more attention during construction to building a tighter house that will be more comfortable, more energy efficient, and save the owner money on fuel bills. The blower door test itself is estimated to cost about $350 and the whole house mechanical ventilation system (a combination of outdoor air intake and exhaust fans) approximately $300. ___________________________________________________________________________________ SIGNIFICANT CODE CHANGES: Other significant code changes include: • A proposed local amendment to delete the section of the code that requires new one- and twofamily dwellings to have fire-sprinklers. Many jurisdictions are removing this requirement, which could add $5,000 or more to the cost of a new home. • A proposed local amendment to delete the section of the code requiring gypsum protection on the underside of I-joists in basements and crawl spaces. This could cost $1,000 in new homes. • A proposed local amendment to clarify dates for Temporary Certificates of Occupancy. • Raising the height of fences exempt from permit requirements from 6’ to 7’. For consistency, a local amendment proposes to keep the current code limit but apply the rules flexibly. • A drip edge is now required at eaves and gables of shingle roofs. • Plastic drain-waste-vent pipe can only be tested by water, not air. A local amendment proposes to delete this requirement, which would cause practical difficulties with no known local benefit. • A new section detailing rules for installing photovoltaic systems, which are rapidly increasing. • Reinstating an amendment requiring spark arrestors for woodstoves in the wildfire hazard area. • Carbon monoxide detectors are required for construction under the International Building Code in occupancy groups R and I with fuel burning appliances or attached garages. • Floor-level exit signs are required in Group R-1 Occupancies (hotels/motels) where general-use exit signs are required. This requirement was in the old Uniform Building Code.

2012 INTERNATIONAL BLDG CODE

• Clarifications to our prescriptive rules for construction in High-Wind Areas, based on evolving engineering standards. Building codes generally require engineered plans in areas with design wind speeds over 110 miles per hour, which includes most of Larimer County. To save homeowners that expense while maintaining public safety, the county has developed and maintains a set of prescriptive rules for high-wind areas, incorporated into the building code. ___________________________________________________________________________________ CLARIFICATIONS TO BUILDING PERMIT FEE TABLE: In addition, the Building Department is recommending clarification to our Building Permit Fee Schedule, Tables 1-A and 1-B, to make the fee structure more transparent. The Building Department has been for many years assessing a one-time “mountain area fee” of $50 to offset the increased costs to perform inspections in remote parts of the county. This fee is not currently listed in the published table. The Building Department has also historically assessed an “investigation fee” for work started without a required building permit. Building codes up through the 1997 Uniform Building Code required an investigation fee “equal to the permit fee” in such cases. That wording was left out of the 2003 I-Codes adopted by Larimer County in 2004. The 2012 I-Codes state that persons commencing work without a required permit “shall be subject to a fee established by the applicable governing authority that shall be in addition to the required permit fees.” Since the code language has changed, the fee must be specified in the adopted fee table. Per a suggestion from the Planning Commission, we propose to rename the investigation fee as a “penalty fee” and to assess an amount “up to or equal to the building permit fee.” Miscellaneous plumbing and mechanical permits are assessed a minimum fee no matter the valuation of the work, but a minimum fee for residential, commercial and utility construction has not been established. At present, the lowest permit price for residential or commercial construction valued up to $500 is $22.24, which does not cover the minimum costs to initiate, review and issue a permit, perform required inspection(s) and finalize the permit. Since a minimum fee is assessed for both plan review and inspections, the Building Official proposes to establish a minimum fee of $43.00 for all permits. ___________________________________________________________________________________ NOTICE OF HEARING: Notice of the public hearing has been posted in local newspapers. The Building Department will hold classes, send out e-mails, post the information on our website, and otherwise communicate as widely as possible the upcoming changes to inform interested parties. ___________________________________________________________________________________ STAFF RECOMMENDATIONS: 1. The Larimer County Planning Commission recommend the Board of County Commissioners (BOCC) adopt the 2012 International Residential Code, 2012 International Building Code, 2012 International Plumbing Code, 2012 International Mechanical Code, 2012 International Fuel Gas Code, 2012 International Energy Conservation Code, 2012 International Existing Building Code, and the 1997 Uniform Code for the Abatement of Dangerous Buildings, with proposed amendments, all to be effective January 1, 2014.
