Buffalo is the largest city in New York outside New York City, about 275,000 residents at the eastern end of Lake Erie. Its Department of Permit and Inspection Services, Room 301, City Hall, 65 Niagara Square, issues permits inside the city, working from the Uniform Code and the Buffalo Green Code.
This guide covers Permit and Inspection Services, the Green Code, the ePermits filing route, and the codes in force.
This guide covers the City of Buffalo. Surrounding Erie County towns such as Cheektowaga and Amherst run their own building departments and are separate authorities.
Buffalo runs a form-based zoning code and files permits electronically. The Buffalo Green Code is a Unified Development Ordinance that replaced the city’s old use-based zoning with form-based districts, and permits are filed through the city ePermits portal with electronic plan review. Plans requiring it carry a New York-licensed architect or engineer seal, and a city licence sits alongside the permit.
What requires a building permit in Buffalo?
Permit required
- New commercial, multi-family and residential construction, additions and change of occupancy
- Structural alterations, load-bearing changes, foundations, decks and retaining walls
- Electrical work — services, panels, circuits, solar and EV charging — under the Uniform Code and the referenced National Electrical Code
- Plumbing under the Plumbing Code of New York State, by a licensed plumber where the jurisdiction requires one
- Mechanical and HVAC change-outs, and work affecting the Energy Code envelope
- Re-roofing above the exempt scope, pools, signs, and demolition
Often exempt
- Minor repairs and maintenance replacing materials in kind
- One-storey detached sheds and playhouses of 144 square feet or less at a one- or two-family home, where the local law exempts them and zoning allows
- Painting, flooring, cabinetry and other finish work
- Like-for-like fixture or appliance swaps with no alteration to wiring or piping
Local amendments and thresholds differ from one jurisdiction to the next, so an exempt list from a neighbouring city is not reliable — a project waved through in one place needs a full permit set in the next. An exemption from a building permit is never an exemption from zoning, the statewide energy code, or any electrical or plumbing permit the municipality requires. Confirm scope with Permit and Inspection Services before work starts.

Several layers apply on top of the base building code and routinely catch projects owners assume are exempt: the 2025 Energy Conservation Construction Code of New York State, which took effect alongside the Uniform Code (its all-electric requirements for new buildings remain suspended by court order, according to the Department of State); the truss-construction identification requirements carried in Executive Law; and, in shoreline and flood-prone areas, floodplain administration under the local flood damage prevention law. Snow and ice loading is a live structural constraint across most of the state. Locally, the City of Buffalo enforces the Uniform Code alongside the Buffalo Green Code, its form-based Unified Development Ordinance adopted in 2017, through Permit and Inspection Services.
New York builds on one statewide code, the Uniform Code, outside New York City; the 2025 edition and 2025 Energy Code took effect on 31 December 2025 (the all-electric provisions remain suspended by court order). Cities, towns and villages administer it, and local standards stricter than the code need Code Council approval. The Uniform Code in New York

Filings go through the city ePermits portal with electronic plan review; in-person building permit applications are taken by appointment on Tuesdays and Thursdays. Buffalo licenses contractors at the city level through Permit and Inspection Services, and mechanical, plumbing and electrical permits are filed by city-licensed stationary engineers, plumbers and electricians; there is no statewide contractor licence.
Zoning is governed by the Green Code, the form-based Unified Development Ordinance, so the zone district and its form standards are confirmed alongside the building review.
Permit types
Not sure this scope needs a permit?
Get a free quote →Residential permits
Residential work is permitted and inspected under the Uniform Code and the Green Code. New construction and additions are reviewed against the form-based district standards, and the city permits accessory dwelling units under the ordinance. Minor in-kind repairs and finish work are generally exempt from a building permit but not from zoning.
Commercial permits
Commercial work goes through department plan review against the Uniform Code, the Energy Code and the fire code, with stamped drawings, and against the Green Code’s form-based district standards. Work not in compliance stays exposed until corrected, re-inspected and found satisfactory before final and the certificate of occupancy.
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 Permit and Inspection Services requires for the specific building before filing.
New York has no state general contractor, home-improvement, electrician or plumber licence; licensing is local (New York City and Nassau, Suffolk, Westchester, Putnam and Rockland counties license home-improvement contractors), and the state sets home-improvement contract rules.

Buffalo permit costs and fees
Budget the city building permit and plan-review fees, separate electrical, plumbing and mechanical permits, and any zoning or board fees tied to the Green Code. Fees are handled through the ePermits 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 | None: New York has no state permit surcharge, and fees are set locally |
| Impact and school fees | Money in lieu of parkland on some subdivisions and site plans, where the local planning board requires it |
| Re-inspections and revisions | Additional fees for failed inspections, revisions and expired permits |
Rather talk it over?
Call 1-855-478-4290 →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 Permit and Inspection Services for the schedule in force on your filing date.

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 Permit and Inspection Services before filing.
Every permit carries an expiration date set by City of Buffalo, which may void a permit if work does not start in time; confirm the expiry on phased or delayed work. Permit validity in New York
Inspections in Buffalo
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. Inspections are requested through the ePermits system, and the certificate of occupancy from Permit and Inspection Services is required before use.
New York inspections are made against the code edition that applied to the permit application, 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 Permit and Inspection Services 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.

Permit records in New York sit with the local authority that issued them. Where the City of Buffalo Department of Permit and Inspection Services is the authority for the City of Buffalo limits, 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.
