What to know before you build
The City lists decks, railings and roofing among the exterior work on Register properties that needs a Historical Commission project review, which is free and part of the permit. Commission staff can approve work that isn’t visible, or has limited visibility, from public rights-of-way. Anything else goes to the Architectural Committee. Setting the deck well back from the front and keeping the pilot house low makes approval easier. Talk to staff at [email protected] early.
The rules are the same citywide
In every Philadelphia neighborhood, roof decks on homes are allowed by the Zoning Code within limits: 5 feet back from the front, a deck surface within 48 inches of the roof’s mid-plane, railings up to 42 inches, and a pilot house of limited size. Every roof deck needs a building permit, and properties on the Philadelphia Register need Historical Commission review. Read the rules guide · See typical costs
