A. INTRODUCTION This information booklet has been prepared by the Colleyville Building Inspection Department to provide homeowners and building contractors a brief summary of the procedures used to obtain a building permit and receive periodic inspections of construction work. Typically, many residential construction projects have similar characteristics and the procedures described in this booklet will generally apply in those situations. However, since construction practices vary, it may become necessary for the building inspector to change or modify these procedures to accommodate the wide range of building and construction techniques found in the construction industry. For questions regarding construction practices not described in this booklet contact the staff of the Colleyville Building Inspection Department who are available to provide assistance with permit applications or to answer questions regarding specific inspection procedures. This information packet is intended to be a helpful reference and does not replace any requirements specified in the codes and ordinances adopted by the City Council. B. BUILDING PERMIT AND INSPECTION DEPARTMENT OFFICE HOURS Building permit applications may be submitted during regular office hours from 8:00 a.m. to 5:00 p.m., Monday through Friday. Inspectors are generally available in the office between the hours of 8:00 a.m. to 9:00 a.m. and 4:00 p.m. to 5:00 p.m. each day. Technical questions must be directed to the inspectors during the above listed office hours. General questions and permit information may be obtained by calling the Building Inspection Department. C. BUILDING PERMIT REQUIREMENTS A building permit is required for new residential construction or for any renovation or addition to an existing residential structure. Building permits may be obtained from the Building Inspection Department.

No construction, grading or dirt movement (including the setting of forms for the future pouring of foundations) of any kind may begin on any lot until an erosion control plan AND an engineered lot grading plan has been submitted and approved by the City. To apply for a building permit, a complete submittal must include ALL OF the following items: 1. Application Form – one (1) copy of the completed permit application indicating the names of the general, concrete, plumbing, electrical and mechanical contractors. The permit application form may be downloaded from the City of Colleyville website www.colleyville.com or is available in the Building Inspection department. 2. Sidewalk Permit Application - The Sidewalk Permit Application form may be downloaded from the City of Colleyville website (www.colleyville.com) or is available in the Building Inspection department. 3. Plot Plan – one (1) copy of a plot plan showing all structures, existing and proposed, and where these structures are or are to be placed in relation to property lines and each other.

City of Colleyville

4. Erosion Control Plan – one (1) copy of a plan showing the location of all erosion control measures. This information may be shown on the plot plan. (An example of an erosion control plan is shown in Section P of this brochure). 5. Engineered Grading Plan – one (1) copy of a site specific, engineered grading plan. 6. Energy Compliance Documentation – The International Energy Conservation Code adopted by the City of Colleyville requires the submittal of documentation at time of building permit application that the proposed structure complies with the minimum energy conservation requirements. Builders can download the necessary computer software at www.energycodes.gov to perform their own energy calculations. Additions to residential buildings that will be heated and/or cooled must comply with the International Energy Conservation Code. For example, all new ductwork to an addition from an existing heating system must be insulated and sealed in accordance with the code. Additions that are not heated and/or cooled, such as an unconditioned garage, need not comply. Contractors must contract with a third-party inspection company for the required Energy Code inspections. A certificate of compliance must be forwarded to the Building Inspection Department prior to Building Final inspection. 7. Construction Plans – two (2) sets of construction plans, 11X17 is acceptable. The construction plans shall include the following items: a. b. c. d. e.

A floor plan of all structures. Window and door sizes. Elevation drawings showing exterior wall construction. Foundation drawings stamped by a professional engineer licensed by the State of Texas. Original letter from the same engineer that designed and sealed the foundation plans stating that the foundation was designed for the soil conditions on that particular lot. The letter must also state that the foundation design criteria comply with the minimum standards required by the 2003 International Residential Code.

D. PLAN REVIEW PROCEDURES Permit applications and all accompanying documents should be submitted to the Building Inspection Department for processing. City staff will review the permit application submittal and provide written comments on the proposed construction plans, which will be returned to the applicant for correction and re-submittal. Where the construction plans do not require major corrections, city staff will complete the plan review process, calculate all applicable fees and notify the applicant that the permit is ready to be issued upon payment of the applicable fees. Most plan reviews can be completed within five working days after submittal of the application. E. PERMIT FEES The City of Colleyville has adopted the permit fee schedules contained in the 1997 Uniform Administrative Code and calculates permit fees based on the estimated construction value of the proposed building. In some instances, the City of Colleyville has established flat rate permit fees for certain types of construction. The City of Colleyville Building Code states that the estimated construction value used for calculating permit fees shall not be less than the square footage construction cost listed in the most recent Building Valuation Data published by the International Conference of Building Officials. Permit fees shall be adjusted on an annual basis for permit applications received on or after the 1st day of June using the most recent edition of the Building Valuation Data. The City of Colleyville Building Code also requires payment of a plan review fee. The plan review fee is a separate fee and is in addition to the permit fee. The current plan review fee for a new single-family residence is $350. No additional plan review fee shall be charged where plans are incomplete or for reviewing a construction plan that has been previously reviewed and re-submitted with corrections. Where construction plans are changed to a new proposal or where a third plan review is necessary, an additional plan review fee is required. F. APPLICABLE CODES AND ORDINANCES The City of Colleyville has adopted and enforces the following codes that are applicable to building construction activities within the corporate limits of the community. 1. 2. 3 4 5. 6. 7.

National Electrical Code – 2002 edition International Building Code – 2003 edition International Plumbing Code – 2003 edition International Mechanical Code – 2003 edition International Fire Code – 2003 edition International Energy Conservation Code – 2009 edition (Effective January 1, 2012) International Residential Code – 2003 edition

P. EROSION CONTROL MEASURES The City of Colleyville Land Development Code requires all residential construction sites to provide erosion control measures until the site is vegetated. The erosion control measures require the installation of silt screening to prevent soil erosion at construction sites from becoming a public nuisance. Applicants seeking a building permit, to construct a new building or to make an addition to an existing building, are required to submit an "Erosion Control Plan" with their building permit application. The building inspector will review the Erosion Control Plan for conformance with the regulations prior to approving the building permit application. The silt screening shall be installed and maintained by the contractor in accordance with these requirements prior to approval of any inspection. An Erosion Control Plan shall at a minimum contain the following items: 1. A site plan drawn to scale of the property where earthwork is proposed showing the property boundary, any street right-of-way and any drainage easement. 2. The existing drainage flow by using arrows to indicate the direction of slope. 3. The location of any existing or proposed building footprint, if applicable. 4. The location and type of erosion control method proposed. 5. The location where access is gained to the property. The following is an excerpt from Ordinance Number O-99-

City of Colleyville

1174, which describes the minimum criteria for an erosion control screen. "Where required by these regulations, there shall be an erosion control barrier constructed according to these standards. The erosion control barrier shall be installed to a minimum height of twelve inches (12”) with the base buried to protect from washout. Said erosion control barrier shall be placed behind any curb and extend across a minimum of 66% of the street frontage of the lot. Additional erosion control barriers may be required to provide erosion control for the entire width of the lot where required by the City Inspector, except at the access point. There shall be a four foot (4') transition section at each end of the barrier. The erosion control barrier shall provide for a minimum of one point of access, which shall be a minimum width of ten feet (10') and a maximum width of twenty feet (20'). The access point shall have a minimum of four inch (4") thick gravel base and extend a minimum of ten feet (10') from the curb. In the absence of any curb, the City Inspector shall determine the proper location of the erosion control barrier."

Q. TREE PROTECTION REQUIREMENTS The City of Colleyville Land Development Code requires all residential construction sites to provide tree protection for trees located on the lot, but outside the building pad site. Trees within the buildable area of a lot may be removed as a part of the normal construction process. All other trees on the lot having a trunk diameter of 3” or more must remain on the lot and be protected from construction activities. The following regulations are applicable to tree protection during residential construction activities: 1. Protective Fencing – All trees shall have protective fencing located at the tree's drip line. The protective fencing may be comprised of snow fencing, orange vinyl construction fencing, chain link fence or other similar fencing with a four-foot (4’) approximate height. The protective fencing may be located within the drip line of the specimen tree for approved construction only. The fencing shall follow the delineation of the approved construction. 2. Bark Protection – In situations where a tree remains in the immediate area of intended construction, the tree shall be protected by enclosing the entire circumference of the tree's trunk with lumber encircled with wire or other means that does not damage the tree. 3. Construction Pruning – In a case where a low hanging limb may be broken during the course of construction, the obtrusive limb may be cut. The limb shall be cut either flush to the trunk on or at the next joint of the limb. The wound shall then be sealed with pruning paint. In no instance shall pruning involve a portion of the trunk or thirty percent (30%) of the entire canopy without the prior approval of the building inspector. 4. Improvements within the Critical Root Zone of a Tree – Design constraints often dictate that trees slated for preservation have some encroachment on their critical root zone. The following is the minimum design criteria that are allowed within the critical root zone of a tree. Development exceeding the criteria would put the tree at risk and therefore no longer be considered a preserved tree. In such a case replacement trees shall also be required.
