Flower Mound, TX Accessory Structures: Shed Rules (2026)

Sheds and accessory storage buildings in Flower Mound are regulated under Chapter 98 of the Code of Ordinances (Zoning). All accessory structures must be architecturally compatible with the primary dwelling in terms of materials, colors, and design. Setback requirements vary by zoning district but generally require accessory structures to be placed behind the front building line and maintain minimum side and rear yard setbacks. A building permit from the Building Department is required for most shed sizes. Structures exceeding 200 square feet or those with electrical or plumbing connections require full permit review and adopted building code compliance. Pre-fabricated sheds under 200 square feet without electrical or plumbing may be exempt from permitting in some jurisdictions, but Flower Mound homeowners should verify with the Building Department as local requirements may be stricter. The Cross Timbers Conservation Development District overlay may impose additional restrictions on accessory structures in environmentally sensitive areas. Most Flower Mound HOAs, including Bridlewood, Wellington, Canyon Falls, and Tour 18, either prohibit visible storage sheds entirely or require architectural review committee approval with specific material, color, and screening requirements.
