Katy treats carports as accessory structures requiring a building permit, with placement governed by the same setback and height rules as other detached accessory buildings.
Carports in the City of Katy are regulated as accessory structures under the zoning ordinance. A permit must be obtained from the Permits and Building Services Department before installation, and carports must comply with residential setback rules. Detached accessory structures generally cannot exceed limited heights when placed within five feet of a property line, and a 15-foot maximum applies within ten feet of a side or rear line. Surveys submitted with permit applications must show the footprint of the carport with dimensions to all property lines.
Installing a carport without a permit, blocking required setbacks, or exceeding allowed height triggers code enforcement notices, fines, and possible removal orders from the city.
