Deck Permit Cost in 2026: Fees, Plan Review and Inspections

A deck building permit in 2026 costs $150 to $600 for most residential projects. Most cities calculate the fee as 1 to 2% of the declared project value, then add a flat plan review fee of $75 to $250 and $60 to $120 per inspection. A typical $14,000 deck pays about $360 to $560 all-in.

How permit fees are calculated

The most common formula is a percentage of project value — usually 1 to 2% — with a minimum fee of $75 to $150. Some cities use a flat fee by deck size instead ($200 to $400 for anything under 500 sq ft), and a few charge per square foot. Your contractor's contract price is the declared value; understating it can void the permit.

The full fee stack

• Building permit — 1–2% of project value ($140–$280 on a $14,000 deck)
• Plan review — $75 to $250 flat, sometimes waived for simple same-footprint rebuilds
• Footing inspection — $60 to $120 (before concrete is poured)
• Final inspection — $60 to $120 (framing, ledger, railing and stairs)
• Zoning or setback review — $0 to $100 in cities that require it

Which decks are exempt

Many jurisdictions exempt freestanding decks that are under 200 sq ft, under 30 inches above grade, and not attached to the house. The exemption varies block by block — some cities require permits for any deck with a roof or any deck over 12 inches high. A five-minute call to the building department is cheaper than a stop-work order, which typically doubles the permit fee as a penalty.

What inspectors actually check

Footing depth below the frost line, post-to-footing hardware, ledger flashing and through-bolts, joist spans, guard-rail height (36 inches minimum in most codes, 42 in some), and stair geometry. Ledger attachment failures cause more deck collapses than every other factor combined, which is why inspectors look at it first.

Frequently asked questions

What happens if I build a deck without a permit?

If caught, expect a stop-work order, a penalty of one to two times the permit fee, and possibly a requirement to expose footings or remove the ledger for inspection. Unpermitted decks also surface at home sale — buyers' inspectors flag them, and some insurers will not cover deck-related injuries on unpermitted structures.

Does the contractor pull the permit or do I?

Either can, but the party who pulls the permit is legally responsible for the work. Reputable contractors pull it themselves and include the fee in the bid. If a contractor asks you to pull the permit as the homeowner, ask why — it often means they are not licensed in your city.

How long does deck permit approval take?

Over-the-counter approval in one to five days for simple decks in most suburbs; two to four weeks in large metros or when plan review is required. HOA approval, if needed, runs on its own clock and should start before the permit application.
