City of Allen Building Inspections Division; Allen residential permit standards — exact city-specific threshold not independently confirmed
Allen generally requires a building permit for a storage shed or accessory structure larger than 200 square feet, or taller than 12 feet; a smaller shed may still need to meet setback and impervious-cover rules. Freestanding decks or patio covers larger than 200 square feet also require a permit. If a property is in a neighborhood with a Homeowners Association, city approval and HOA architectural approval are separate processes and both may be required before construction.
