The Building and Permits Department is responsible for the health, safety and welfare of our residents. The City of Katy is a Zoned City, and we do require permits to be obtained from the building department BEFORE work is started. Permits are required for all new construction. In addition to new structural construction, permits are required for any remodeling or roofing, installation of air conditioning and heating systems, electrical, plumbing, swimming pools (in ground and above ground) and hot tubs, storage buildings, carports, garages and workshops, sidewalks, driveways, patios, lawn irrigation systems, water heaters, adding or removing walls, demolition of structures, house moving and mobile homes.

For the safety of our citizens, professional, well-trained Inspectors insure building standards are met. Information is available to walk you through the permits and inspections process. Our Inspectors will meet with you for a pre-construction consultation.

The Building Department approves all new construction and proposed improvements of existing structures to make sure they conform to all adopted building codes and city ordinances. Final approval of all plans, permits and inspections rests with this department, assuring owners of sound construction.

EFFECTIVE JANUARY 1, 2019: The City of Katy has adopted the 2015 International Building Codes and the 2017 National Electrical Code. Any plans submitted after January 1, 2019 must comply with the 2015 International Building Codes and the 2017 National Electrical Code.

Please feel free to contact the Building Department at 281-391-4830 with any questions you may have. We are here to help you through the building process. The homeowner is responsible for seeing proper permits have been obtained before work begins on their property. View the City’s Ordinances, including zoning.
