Do You Need a Permit for Your Deck?
Almost certainly yes — if your deck is attached to the home, elevated over 30 inches, or exceeds 200 square feet. Building without a permit can result in forced demolition, inability to sell, voided insurance, and personal liability.

- Decks over 200 sq ft: Permit required in almost all U.S. jurisdictions
- Decks over 30 inches high: Permit required in most states
- Attached decks: Permit required regardless of size
- Decks with electrical: Always require permit
