Huntington is a Suffolk County town of about 206,000 residents on the north shore of Long Island. Its Building & Housing Division, part of the Engineering Services Department in Town Hall, Room 115, 100 Main Street, issues permits for the unincorporated town, alongside the incorporated villages inside it.
This guide covers the Building Division, the Suffolk County licence, the village trap, and the codes in force.
This guide covers the Town of Huntington. The incorporated villages inside the town, such as Northport and Lloyd Harbor, are separate authorities with their own building departments.
Incorporated villages such as Northport and Lloyd Harbor file separately, and Suffolk County licenses home improvement contractors. A parcel inside a village files with the village, not the town. Home improvement contractors need a Suffolk County licence, and north-shore harbour and bluff parcels carry slope, drainage and coastal conditions under local law.
What requires a building permit in Huntington?
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 Division 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 Town of Huntington enforces the Uniform Code through the Building Division within Engineering Services on Main 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 in the unincorporated town is permitted and inspected under the Uniform Code and the town’s local law. Bluff and harbour parcels can carry slope, drainage and coastal conditions. Minor in-kind repairs and finish work are generally exempt from a building permit but not from zoning.
Commercial permits
Commercial work goes through division plan review against the Uniform Code, the Energy Code and the fire code, with stamped drawings. Harbour-front commercial work carries coastal and, where applicable, waterfront review.
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 Division 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.

Huntington permit costs and fees
Budget the town building permit and plan-review fees, separate trade permits, and any drainage or coastal submission fees on north-shore parcels. The Suffolk 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 Division for the schedule in force on your filing date.

A parcel inside an incorporated village files with the village.
Home improvement contractors register with the county Department of Labor, Licensing and Consumer Affairs.
Bluff and harbour parcels carry drainage and coastal review.
Commercial and larger residential work needs an architect or engineer seal.
Drawings, trade permits and coastal submissions as they apply.
The division inspects to plan and reviews drainage and coastal work.
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 Division before filing.
Every permit carries an expiration date set by Town of Huntington, 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 Huntington
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 division inspects to the approved plans and reviews drainage and coastal conditions where they apply.
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 Division 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 Town of Huntington Building & Housing Division is the authority for the Town of Huntington outside its incorporated villages, 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.
