A building permit is required for any new structure, building addition, or remodeling project taking place in the City of Benbrook. Only one-story detached accessory buildings less than 120 square feet (storage buildings, playhouses, etc.) and retaining walls less than 4 feet (4') in height are exempt; these structure must still meet setback requirements. The Benbrook City Council has adopted minimum standards for construction and materials to protect life, health, and safety.
