Do You Need a Deck Permit in Philadelphia?

Permit Exemption

Philadelphia requires a permit for virtually all decks. The EZ Deck Permit streamlines the process for decks ≤160 sq ft (or ≤216 sq ft with intermediate posts) attached to a single-family dwelling in the rear yard, with no roof, walls, or hot tub. Decks not exceeding 30 inches above grade still require zoning approval.

If your deck does NOT meet all exemption criteria, you must obtain a permit before construction. Building without a required permit can result in fines, stop-work orders, and required demolition.
