New York City is the largest city in the United States, about eight and a half million residents across the five boroughs of Manhattan, Brooklyn, Queens, the Bronx and Staten Island. Its Department of Buildings, at 280 Broadway with an office in each borough, is the sole building authority in the city and works from the New York City Construction Codes, not the statewide Uniform Code.
This guide covers the Department of Buildings, the licensed-filer system, Local Law 154, the trade licences and the codes in force.
This guide covers the City of New York, all five boroughs. New York City is carved out of the statewide Uniform Code and runs its own construction codes through the Department of Buildings.
New York City does not run on the statewide Uniform Code, and most work must be filed by a licensed professional. Construction documents are filed with the Department of Buildings by a registered design professional or licensed contractor who takes responsibility for the work, and trade permits file under a licensed master. On new construction, Local Law 154 bars most fossil-fuel combustion, making new buildings effectively all-electric on a phased schedule.
What requires a building permit in New York City?
New York City is the one place in the state that does not run on the statewide Uniform Code. The city is carved out of it entirely and enforces its own New York City Construction Codes — a building, plumbing, mechanical, fuel gas and electrical code set maintained by the city and administered by the Department of Buildings through its borough offices, not by the Department of State. So the first question in New York City is not which town or village holds jurisdiction, as it is elsewhere in the state, but which Department of Buildings work type and filing representative your project needs. The Department of Buildings administers the New York City Construction Codes, most recently updated in the 2022 edition, through its borough offices rather than the statewide Uniform Code.
Permit required
- New buildings, enlargements, alterations and change of occupancy or use
- Structural alterations, load-bearing changes, foundations, facades and retaining walls
- Electrical work under the New York City Electrical Code, filed under a licensed master electrician
- Plumbing and gas work filed under a licensed master plumber
- Mechanical and HVAC change-outs, boilers, and work affecting the energy envelope
- Sidewalk sheds, scaffolds, demolition, curb cuts, signs and place-of-assembly work
Often minor / no permit
- Ordinary repairs replacing materials in kind, as defined by the codes
- Painting, plastering, flooring, cabinetry and other finish work
- Like-for-like fixture swaps with no alteration to wiring or piping
- Cosmetic work that does not affect fire protection, egress or structure
The definition of an ordinary repair is narrower than owners expect, and an exemption from a Department of Buildings permit is never an exemption from the Zoning Resolution, the fire code, or the energy code. Confirm the work type and filing route with the Department of Buildings before work starts.
The city layers that apply on top of the base codes
Several New York City layers routinely catch projects owners assume are simple: the New York City Energy Conservation Code, the city’s own energy code rather than the state ECCCNYS; Local Law 154 of 2021, which bars most fossil-fuel combustion in new buildings and makes new construction effectively all-electric on a phased schedule; and, for larger existing buildings, the emissions limits of Local Law 97. Sidewalk-shed and facade-inspection obligations, and flood-zone construction standards in coastal and waterfront areas, apply on top again.
Who handles permitting in New York City?
The Department of Buildings reviews plans, issues permits and inspects construction across all five boroughs, working from the New York City Construction Codes.
| Detail | Information |
|---|---|
| Authority | New York City Department of Buildings |
| Serves | All five boroughs of New York City |
| Phone | 212-566-5000 |
| Counter | 280 Broadway, Manhattan, plus borough offices; Mon-Fri |
| Code | New York City Construction Codes, 2022 edition |
| Filing | Electronic filing by a licensed professional |
| Licensing | DCWP Home Improvement licence; DOB registrations |
| Records | Permit and inspection records held by the department |
Most filings go through the department’s electronic system and are submitted by a licensed professional. Residential contractors performing work over two hundred dollars need a Home Improvement Contractor licence from the Department of Consumer and Worker Protection, and general contractors on larger jobs register separately with the Department of Buildings.
Electrical and plumbing work files under a licensed master electrician or master plumber, credentialed by the department itself. A licence from a neighbouring county carries no weight inside the city.
Permit types
Residential permits
Residential work is filed with the Department of Buildings under the New York City Construction Codes and the New York City Energy Conservation Code. Small cosmetic work such as painting and flooring is generally an ordinary repair, but the definition is narrow and alterations affecting egress, structure or systems need a permit. Local Law 154 applies to new buildings and qualifying gut renovations.
How New York contractor credentials work
New York does not license general contractors at state level. There is no state contractor licence, no state exam and no state board for general contracting. Licensing is a city and county matter, and the requirements change as you cross a municipal line. The state regulates home improvement contract terms through General Business Law Article 36-A rather than licensure, so a written contract obligation can apply even where no licence does.
In New York the licence lives with the locality, not the state. A registration issued by one county does not authorise work in the next, and a contractor working across the metropolitan region routinely holds several at once. Confirm which licence the permitting authority requires for the specific parcel before filing, along with workers’ compensation and disability benefits coverage.
Commercial permits
Commercial work is filed under the New York City Construction Codes with plans stamped by a New York-licensed architect or engineer, and routes through the department’s plan examination. Place-of-assembly, facade, sprinkler and elevator work carry their own filings, and Local Law 97 emissions limits apply to larger existing buildings.
Licenses, trade classifications and design professionals
Practically, three credential layers appear on New York projects: the local home improvement or contractor registration where the jurisdiction issues one; separately licensed electrical and plumbing trades, licensed locally rather than statewide; and, on commercial and larger residential work, drawings stamped by a New York-licensed architect or professional engineer. Confirm what the Department of Buildings requires for the specific building before filing.
New York City permit costs and fees
Budget the Department of Buildings filing fees, which are set by work type and valuation, plus separate electrical and plumbing permit fees, and the state and city surcharges collected with the permit. Fees are paid through the department’s electronic system as part of the filing sequence.
| Fee component | How it works |
|---|---|
| Building permit | Based on project valuation or square footage; set by the local schedule |
| Plan check | A percentage of the permit fee or a flat charge, at submittal |
| Trade permits | Separate electrical, plumbing and mechanical fees |
| State surcharges | Building Standards and seismic (SMIP) fees collected with the permit |
| Impact and school fees | Development impact and school-district fees in growth areas |
| Re-inspections and revisions | Additional fees for failed inspections, revisions and expired permits |
New York does not layer a uniform statewide permit surcharge on local charges the way some states do, so the fee is substantially local: each city, town and village sets its own schedule by local law, and neighbouring municipalities on the same road can price the same job differently. A figure from a neighbouring town is not reliable — ask the Department of Buildings for the schedule in force on your filing date.

Trade permits and who may pull them
In New York City the trades run on the city’s own construction codes and on Department of Buildings licences, not on the statewide books. Electrical and plumbing work is filed under a licensed professional who takes personal responsibility for it, and the trade permit generally cannot be issued until the associated work is properly filed.
New York City licenses the trades directly through the Department of Buildings. Plumbing and gas work files under a licensed master plumber, and electrical work under a licensed master electrician, each carrying the permit under their own licence. A credential from a neighbouring county carries no weight inside the city. Confirm both the permit and the licensed filer with the Department of Buildings.
- Electrical work follows the New York City Electrical Code, filed under a licensed master electrician.
- Plumbing and gas work follows the New York City Plumbing and Fuel Gas Codes, filed under a licensed master plumber.
- Mechanical work follows the New York City Mechanical and Energy codes.
Permit required
- Service installations, panel upgrades, new circuits, solar PV and EV chargers
- New plumbing, repipes, water heater change-outs, fixtures, backflow and gas piping
- HVAC installation and change-out, boilers, ductwork, venting and commercial kitchen exhaust
- Sprinkler, standpipe and fire alarm work on commercial and multi-family structures
Typically minor
- Replacing a fixture, switch, receptacle or light with no alteration to wiring or piping
- Clearing a stoppage without replacing or rearranging concealed piping
- Filter, thermostat and routine component service
- Like-for-like appliance repair that does not alter the connection
How to apply for a New York City building permit
New York City classifies work by type, which sets the filing path.
Most work is filed by a registered design professional or licensed contractor.
Home Improvement, general-contractor registration and master trade licences as they apply.
New buildings and qualifying gut renovations must be effectively all-electric.
Plans and fees go through the department system.
Inspections and the certificate of occupancy follow the work type.
Review, corrections and what actually causes delay
In New York, the first cause of delay is uncertainty over jurisdiction — filing with a town when an incorporated village inside it holds the authority, or assuming a county issues permits when it generally does not. After that come Energy Code documentation, a contractor registration that the jurisdiction does not recognise, and, in shoreline and flood-prone areas, floodplain requirements that were not addressed up front. Build the plan-review time into the schedule and confirm the checklist with the Department of Buildings before filing.
Approvals do not stay live indefinitely. A New York building permit carries a validity period and can expire if work does not start or stalls between inspections. On phased or financed work, keep the permit active with periodic progress inspections and confirm the expiry window before it passes.
Inspections in New York City
Where a permit is required, standard checkpoints include footing and foundation, framing, rough-in electrical, plumbing and mechanical, insulation and Energy Code compliance, fire systems on commercial work, and final, with a certificate of occupancy before use. The department schedules required inspections through its electronic system, and sign-off and the certificate of occupancy follow the code path for the work type.
New York inspections are keyed to the code edition in force when the permit issued, so the approved plans and the Energy Code documentation need to be on site for the inspector to check against. Local code enforcement officials are certified by the state, and the municipality reports its enforcement activity to the Department of State. Confirm the notice the Department of Buildings needs and schedule around its inspection windows.
Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, product listings, Energy Code documentation and your correction responses available on site.
New York City permit search and official resources
Permit records in New York sit with the local authority that issued them. Where the New York City Department of Buildings is the authority for the City of New York, it holds the building permit, the inspection history and the certificate of occupancy or compliance. If you are buying, refinancing or renovating, confirm that past work was permitted rather than assuming it was — open permits and missing certificates are a common closing problem in this state.
Confirm the authority having jurisdiction first. New York enforces one statewide Uniform Code outside New York City, but towns, villages and cities each administer it with their own local law, fee schedule and staffing, so the requirements that apply vary by parcel — and a village inside a town is its own authority. Confirm current requirements, fees and review turnaround for your filing date.
