Rowlett, TX Accessory Structures: Shed Rules (2026)

Rowlett's published Accessory Building Regulations (Development Code Section 77-303) govern storage buildings, sheds, workshops, greenhouses, and similar detached structures, and a permit is required for all of them. The number and size of accessory structures on a residential lot are limited by the maximum lot coverage of the zoning district or 35 percent of the rear yard, whichever is less. An accessory structure may not exceed the height of the primary structure or the zoning district's maximum height, whichever is less; structures in the front yard cannot exceed seven feet in height. Setbacks depend on placement: a structure in the front or side yard must meet the same front and side setbacks as the house, while a structure in the rear yard needs a minimum three-foot side setback from the neighbor's property line. Any enclosed accessory structure over 500 square feet in a residential district requires a Special Use Permit, after which a building permit is issued. All accessory buildings must resist a 115 mph wind load and cannot be placed over underground gas lines or on any easement. Enclosed structures must use exterior wall materials that comply with the adopted building code. The permit fee is $75 for buildings under 250 square feet, or $75 plus 10 cents per square foot for larger buildings.
