New Jersey permit-fee context
Highest fees outside California + Hawaii. NJ has both a state DCA fee + municipal fee; Bergen + Hudson + Essex run higher.
Why deck? Single building permit; modest valuation. Higher if >30in above grade (most). Coastal/freeze zones add structural review.
What this fee does NOT include
- Plan-review service fees (typically 0.5–1% of cost, separate line)
- Per-trade fees (plumbing, electrical, mechanical — $50–$200 each)
- State-level surcharges (FL DBPR, NJ DCA, OR BCD, etc.)
- Contractor's filing/processing fee
Rule of thumb: budget 1.5–2× the base permit fee for the all-in cost.

FAQ — Deck permits in New Jersey
How much is a deck permit in New Jersey in 2026?
On a typical $9,000 deck project in New Jersey, the statewide median permit fee runs $175 — about 1.94% of project cost. Major metros run higher: Jersey City $181, Newark $175, Trenton $175. Highest fees outside California + Hawaii. NJ has both a state DCA fee + municipal fee; Bergen + Hudson + Essex run higher.
Why is the fee higher in major New Jersey metros?
Each New Jersey city/county sets its own multiplier on top of the state base rate. Jersey City runs 1.4× because of stricter plan review + structural review + energy-code overhead. Trenton sits lower (1.1×) because of less plan-review depth + simpler intake. Rural counties in New Jersey often have flat-fee schedules below even the lowest metro.
What's included in the permit fee vs. what's billed separately?
The permit fee covers the building department's intake + base review. NOT included: plan-review service fees (often a separate line, 0.5–1% of project cost), per-trade fees for plumbing/electrical/mechanical (typically $50–$200 each), and any state-level surcharges (FL adds DBPR 1.5%, NJ adds DCA, OR adds 12% BCD surcharge). Your contractor's filing fee is also separate. Budget 1.5–2× the base permit fee for the all-in cost.
Can I skip the permit and save the fee?
Don't. Working without a required permit fails any future resale inspection (the buyer's inspector WILL flag it), voids your homeowner's insurance for any related claim, and triggers retro-permitting fines that are typically 2–3× the original fee. New Jersey treats unpermitted deck work as a separate violation under state building code. The "savings" become a $1,500 problem at resale on a $500 fee.
