How to apply in Philadelphia
In Philadelphia, a residential deck permit application is a set of construction documents that show what will be built and prove it meets the IRC deck provisions. In practice that means a scaled site plan locating the deck and its setbacks, plus deck plans and structural details covering the footings, posts, beams, joists, ledger, guards, and stairs.
What most deck permit applications include:
- For Philadelphia, a permit application identifying the work, the deck's size (square footage), and whether electrical work such as lights or receptacles is included, submitted for plan review before construction begins (IRC R106).
- For Philadelphia, a scaled site plan (for example 1/4 inch to 1 foot) showing the new deck's location relative to the house, its overall length and width, and dimensioned distances from the deck to all property lines and other structures so required setbacks can be verified (IRC R106.1.1).
- For Philadelphia, a deck plan drawn to scale showing overall dimensions and the framing layout: joist size, spacing, span, and species; beam size and span; post size and height; and footing or pier size and depth (IRC R507.4 posts, R507.5 beams, R507.6 joists, R507.3 footings).
- For Philadelphia, a section or side elevation with connection details showing the ledger attachment to the house band joist with flashing, the fastener or bolt schedule, joist hangers, post-to-beam and post-to-footing connections, and the required lateral load connection (IRC R507.9 ledger connection, R507.9.2 lateral connection, R507.2.4 flashing).
- Footing sizing derived from tributary area, the soil bearing value, and design loads per IRC Table R507.3.1, with footings shown bearing on undisturbed soil at the frost depth required by the jurisdiction (IRC R507.3).
- Details for the guards required where the walking surface is more than 30 inches above grade, and for the stairs and handrails, showing guard height and opening limits, stair riser and tread dimensions, and handrail location (IRC R312 guards, R311.7 stairs and handrails).
- For designs that fall outside the prescriptive R507 tables (for example multi-story or stacked decks, or a ledger attached to a cantilever), engineered and stamped structural plans are submitted in place of the prescriptive details (IRC R507.1 and R301).

Inspections and closing out your permit
In Philadelphia, deck work is inspected in sequence as it is built: the footings before concrete is placed, the framing before the decking boards go down, and a final inspection once the deck is complete. Each stage checks the items that would be hidden or unsafe if missed.
- Footing or pier inspection in Philadelphia: after the holes are dug and any forms or reinforcing are set but before concrete is placed, the inspector checks footing depth and diameter, a flat undisturbed bearing surface, and that the holes are free of water (IRC R109.1.1 foundation inspection; R507.3 footings).
- Framing inspection in Philadelphia: after the deck is framed but before the decking conceals it, the inspector verifies the ledger attachment and its flashing, the fastener and bolt schedule, joist hangers and metal connectors, post-to-beam and post-to-footing connections, and the lateral load connection; call it before decking is installed (IRC R109.1.4 frame inspection; R507.9 ledger and flashing).
- Final inspection in Philadelphia: after the deck is complete and before it is used, the inspector confirms guard height and opening limits (a 4 inch sphere must not pass, 4 3/8 inch at stairs), stair riser and tread dimensions, handrail height and graspability where there are 4 or more risers, stair landings, and required stair lighting (IRC R109.1.6 final inspection; R312 guards, R311.7 stairs and handrails).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Philadelphia permit portal or by phone at (215) 255-4040.

- Where do you apply for a deck permit in Philadelphia?

- Can a homeowner pull a deck permit themselves in Philadelphia?
- Under Pennsylvania law (34 Pa. Code 403.62(a); Act 132 of 2008 (HICPA), Section 2 (73 P.S. 517.2)): Yes. 34 Pa. Code 403.62(a) provides that 'An owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish or change the occupancy of a residential building or erect, install, enlarge, alter, repair, remove, convert or replace an electrical, gas, mechanical or plumbing system regulated by the Uniform Construction Code shall first apply to the building code official and obtain the required permit.' The owner is a permitted applicant. The Home Improvement Consumer Protection Act (Act 132 of 2008, 73 P.S. 517.1 et seq.) is a registration and consumer-protection law for contractors: its 'Contractor' definition covers a person 'who owns and operates a home improvement business or who undertakes, offers to undertake or agrees to perform any home improvement,' so it governs people doing home improvements for others, not homeowners doing their own work. Pennsylvania has no statewide trade licensing barring homeowner work; trade licensing, where it exists, is municipal. Confirm how Philadelphia applies this before you apply.
