How Much Does a Building Permit Cost in New York?

Do You Need a Permit?

New York's Administrative Code Table 28-112.2 prices alterations to one-, two- and three-family dwellings at a $130 minimum for the first $5,000 of cost, plus $2.60 for each additional $1,000 or fraction. Department rule 1 RCNY 101-03 adds a $45 records-management fee to each new-building and alteration application for those dwellings. So an $8,000 job is $182.80, a $12,000 job $193.20, and a $25,000 job $227.00.

Common examples: $10,000 of siding is $188.00, a $7,100 deck $182.80, and a $2,400 interior strip-out, which files as an alteration, $175.00. Demolishing a building starts at $260.

Trade permits are separate. Electrical permits under 101-03 are $40 plus per-item charges: $30 for a 101-200 amp service switch, $15 or $37.50 per panel depending on breaker count, $15 to $75 per set of service cables depending on size, and 25 cents per outlet beyond the first ten. A new EV charger circuit is one outlet, inside the first ten units that carry no item charge, so it is the $40 filing fee alone; 84 of 118 recent one- and two-family EV-circuit filings were billed exactly that. A panel total depends on the breakers and conductors the electrician declares, and filings for the same job vary, so that figure is pending confirmation from DOB. A 6 kW rooftop solar system stays inside the first ten units, so its electrical permit is the $40 filing fee, and a $25,000 kitchen, with its alteration filing and electrical permit, comes to $254.

Most work on a building needs a permit in New York, but 1 RCNY 101-14 lists work that does not. Reroofing limited to the membrane, roof coverings, cant strip and insulation above the deck needs no permit, as long as the energy code does not require added roof insulation; replacing the deck or sheathing does. Replacing existing windows needs no permit if the window is not on the lot line, the masonry opening does not change, light and ventilation are not affected, and the operable area stays the same.

Fences 6 feet or less at a one- or two-family home are exempt. Refrigerating systems of 25 tons or less using a Group A1 refrigerant are exempt, which depends on the equipment you install. Since February 22, 2026 (Local Law 142 of 2025), replacing a gas water heater of 350,000 BTU or less in a home of five families or fewer, without moving the shutoff valve, is ordinary plumbing work that needs no permit; the plumber reports it on form OP128 with a $130 fee.

New York penalizes work done without a permit, and the Department of Buildings can issue stop work orders once it learns of the work. Violations tend to surface through complaints, sales and insurance claims.

We have not captured the current penalty schedule from a primary source, so we do not quote a multiplier here. Pull the permit before work starts.

Permit validity and renewal run through the Department of Buildings' DOB NOW system. We have not captured the current expiration rule from a primary source, so check the dates on your permit and renew before it lapses.

New York leans hard on licensed professionals. Plumbing work is filed by a licensed master plumber and electrical work by a licensed master or special electrician. Your contractor should pull the permit in their name. If they ask you to pull it as the homeowner, that is a red flag: it shifts liability to you and often means they aren't properly licensed.

New York writes its own construction codes rather than adopting the national models unchanged, and its fee schedule is split the same way: building alterations on one table, electrical on a per-item rule, and a flat records fee on every 1-3 family alteration application.

The upside is that a lot of common exterior work needs no permit at all. The catch is that trade permits are priced item by item, so ask your contractor to list each one.

How much does a building permit cost in New York?

For a one- to three-family home, an alteration permit is $130 for the first $5,000 plus $2.60 per additional $1,000, plus a $45 records fee: $193.20 on a $12,000 job and $227.00 at $25,000. Trade permits are separate.

Do I need a permit to replace a water heater in New York?

No permit, but a filed report. Since February 22, 2026, a like-for-like gas water heater replacement in a home of five families or fewer is ordinary plumbing work under Administrative Code 28-105.4.4 as amended by Local Law 142 of 2025, as long as the shutoff valve is not moved. A licensed master plumber reports it to the Department of Buildings on form OP128: Heat & Hot Water, with a $130 fee. A plumber may report several jobs on one form, so $130 is the most a single job pays.

How much is a plumbing permit in New York?

Plumbing permits use the same Table 28-112.2 alteration fee as building work: $130 for the first $5,000 of plumbing cost plus $2.60 per additional $1,000.

Do I need a permit to build a deck in New York?

Yes. A $7,100 deck is $130 plus 3 x $2.60 on Table 28-112.2, plus the $45 records fee, for $182.80.

Do I need a permit for electrical work in New York?

Most electrical work needs a permit filed by a licensed electrician. Under 1 RCNY 101-03 it is $40 plus per-item charges for service switches, panels, cables and outlets over ten, so the total depends on the equipment.

Why does New York issue so many separate permits for one job?

New York prices building alterations, plumbing and mechanical work on Table 28-112.2 and electrical work item by item under 1 RCNY 101-03, and each is a separate filing. The city writes its own codes instead of adopting the national models unchanged.
