Sherman, TX Accessory Structures: Shed & Carport Rules (2026)

Section 14.04.002 applies to all accessory buildings and structures in residential zoning districts in the City of Sherman, Texas. Accessory buildings in non-residential districts follow the standards of the applicable district instead.

Location. No accessory building or structure is allowed in the front yard, and none is allowed in the required side yard unless the section says so. Each one must be separated from the main building or other structures by at least 5 feet and needs a rear and interior side yard setback of at least five (5) feet. Next to a side street, the minimum side yard setback is fifteen (15) feet, except for garages or carports. Detached garages or carports facing an alley or side street must be set back twenty (20) feet. Nothing can be built in a drainage or utility easement.

Size and placement. Accessory buildings of less than 500 square feet can be located within the required rear yard, subject to the setbacks above. Buildings of 500 square feet or greater must be located in the building area, which is the area inside the required yards and setbacks. The footprint of every accessory building counts toward the building area calculation for the lot. An accessory building attached to the primary building is treated as part of it and follows the primary building's setbacks.

Portable shed exemption. A portable storage shed escapes the building permit and the side and rear setbacks only if it is 100 square feet or less in floor area, less than eight (8) feet tall, freestanding and moveable with no permanent foundation, at least two (2) feet from side and rear lot lines, and free of plumbing and electrical installations.

Use. No accessory building can be rented or leased, and none can be used for commercial purposes. Every other shed or accessory building needs a building permit, an inspection by the city and compliance with the article. The section was last amended by Ordinance 6934 adopted 5/4/2026.
