White Plains is the Westchester County seat, a city of about 63,000 residents with a dense downtown core. Its Building Department at 70 Church Street reviews plans and issues permits inside the city under the Uniform Code.
This guide covers the Building Department, the Westchester County licence, the downtown high-rise context, and the codes in force.
This guide covers the City of White Plains, the Westchester county seat. Neighbouring Westchester municipalities such as the Town of Greenburgh and Harrison run their own building departments and are separate authorities.
White Plains is a high-rise downtown under the Uniform Code, and Westchester County licenses home improvement contractors. Home improvement contractors working in the city need a Westchester County licence. The dense downtown core brings high-rise, mixed-use and transit-oriented development, so site-plan, fire and change-of-occupancy review figure heavily alongside the building permit.
What requires a building permit in White Plains?
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 the Building Department 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 White Plains enforces the Uniform Code through its Building Department at 70 Church Street, with amendments adopted by local law.
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

Residential permits
Residential work is permitted and inspected under the Uniform Code and the city’s local law, from downtown high-rise units to established neighbourhoods. Larger residential development carries site-plan and fire review. 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. Downtown high-rise and mixed-use work carries site-plan, fire and change-of-occupancy review alongside the building permit.
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 Building Department 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.

White Plains permit costs and fees
Budget the city building permit and plan-review fees, separate electrical, plumbing and mechanical permits, and any site-plan or board fees on downtown projects. The Westchester County licence and worker coverage sit alongside the permit.
| 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 the Building Department for the schedule in force on your filing date.

Neighbouring Westchester municipalities are separate authorities.
Home improvement contractors register with county Consumer Protection.
High-rise and mixed-use work carries site-plan and fire review.
Commercial and larger residential work needs an architect or engineer seal.
Drawings, trade permits and site submissions as they apply.
The department inspects and issues the certificate of occupancy.
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 Building Department before filing.
Every permit carries an expiration date set by City of White Plains, 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 White Plains
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 inspects to the approved plans, and a certificate of occupancy from the city 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 the Building Department needs and schedule around its inspection windows.

White Plains permit search and official resources
Permit records in New York sit with the local authority that issued them. Where the City of White Plains Building Department is the authority for the City of White Plains 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.
