Lewisville, TX Accessory Structures: Shed Rules (2026)

Lewisville permits accessory storage buildings and sheds in residential zoning districts. Sheds under 120 square feet and not on a permanent foundation generally do not require a building permit, but they must still comply with all zoning setback requirements. Accessory structures must be placed in the rear yard only and maintain at least 5 feet from side and rear property lines. Structures over 120 square feet require a building permit from the Inspections Division at (972) 219-3480. All accessory structures must be constructed of materials compatible with the primary dwelling. Metal storage containers and shipping containers are not permitted as accessory structures in residential zoning districts. The combined footprint of all accessory structures cannot exceed a percentage of the rear yard area as defined in the Unified Development Code. The maximum height for accessory structures is typically limited to one story or the height of the primary dwelling, whichever is less. Sheds cannot contain plumbing fixtures or be used as habitable space without meeting additional building code requirements. They cannot be placed within drainage or utility easements.
