Putnam County, New York Building Permit Guide

Putnam County does not issue building permits. The towns of Carmel, Kent, Patterson, Philipstown, Putnam Valley and Southeast and the villages of Brewster, Cold Spring and Nelsonville each run their own building department. The county still shapes almost every project: its Department of Health must approve septic systems, wells and any change to a house’s bedroom count before a town can issue, its Office of Consumer Affairs licenses the electricians, plumbers and home-improvement contractors who do the work and takes electrical permits in six of the nine municipalities, and its Department of Public Works permits work along county roads.

What requires a building permit in Putnam County?

The municipal lists decide this, and they reach well past new houses. Putnam Valley keeps separate applications for fences and walls, generators, gas piping, HVAC, plumbing, outdoor wood boilers, minor grading, rock hammering or shattering, tents and short-term rentals. Cold Spring’s adopted fee schedule prices replacement windows, doors, roofs and siding, gas lines, wood or pellet stoves, fuel tanks and pools. In the Town of Southeast every pool and every fence or wall needs a permit, while Carmel does not require one for a fence. Patterson asks for one for every roof replacement and every pool at least 24 inches deep, inflatable ones included.

What the towns and villages decide and what the state holds

All nine municipalities enforce the same state construction rules, the 2025 Uniform Code and Energy Code, and Putnam Valley tells designers that plans have had to meet the 2025 codes since January 1, 2026. Local rules sit around that code: zoning, wetland and steep-slope laws, historic districts, fee schedules and exemption lists. Philipstown’s department reminds designers that the town is a stretch code community. Putnam County is not among the twelve counties the Department of State lists as having opted out of the enforcement of the Uniform and Energy codes.

Putnam County building department: who handles permitting

Every Census-listed municipality is below, with its building office and where electrical permits go. A town department works only outside the villages inside it: Brewster sits in the Town of Southeast, and Cold Spring and Nelsonville sit in Philipstown.

The most common wrong turn is a Brewster mailing address: it can belong to the village or to the Town of Southeast, which keep separate files and applications. Likewise a Cold Spring address may be inside the village or out in Philipstown, and the town’s building department sits in Town Hall on Cold Spring’s Main Street.

What Putnam County itself does

• Department of Health, Environmental Health (1 Geneva Road, Brewster; 845-808-1390): approves septic construction permits and realty subdivision plans, issues well-drilling permits, approves repairs to existing septic systems and reviews house renovations and additions for their bedroom count. In the New York City watershed it decides whether a septic application is delegated to the county or reviewed jointly with the city’s Department of Environmental Protection, and either way it issues one approval for both agencies.
• Office of Consumer Affairs (110 Old Route 6, Building 3, Carmel; 845-808-1617): runs the Electrical Board, the Home Improvement Board and the Plumbing/Mechanical Trades Board, and files electrical permits for Kent, Philipstown, Southeast and the three villages.
• Department of Public Works (842 Fair Street, Carmel; 845-878-6331): permits any work on or along a county road.
• Planning, Development & Public Transportation (845-878-3480): reviews the zoning, site plan and subdivision actions that towns and villages must refer to it under General Municipal Law section 239 before deciding; technical help is by appointment.

Putnam County permit types and applications

Residential permits

Each office has its own forms. Putnam Valley accepts applications only on weekdays from 10 a.m. to 3 p.m. and turns away incomplete ones. Cold Spring charges nothing to file: the clerk takes the application with sketches or plans at Village Hall or by post, and the Building Inspector then asks for the balance of the fee, proof of workers’ compensation, the contractors’ Putnam County license numbers and two sets of plans stamped by a New York architect or engineer, as the job requires. Nelsonville revised its building permit application in December 2024. Any job that touches the floor plan or adds living space on a septic lot needs the county Health stamp before the town or village can issue, and the Health application can be picked up at the town building departments.

Commercial permits

Commercial projects add site plan review by the local planning board, and in most cases a fire-code operating permit. For a new restaurant, deli or grocery store, county Health engineers must approve the septic or sewer arrangement and the water supply before it opens. The county’s design bulletins split the work by type: S-19 for single-family homes, RS-21 for realty subdivisions and CS-31 for commercial development.

For tenant improvements and new commercial builds, Alliance handles commercial permit applications through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Zoning boards: a denial by the building inspector is appealed to the local zoning board of appeals; in Cold Spring the appeal must be filed within sixty days, and a variance lapses if no building permit follows within a year.
• Historic review: exterior changes inside Cold Spring’s historic district need a certificate of appropriateness from the Historic District Review Board, which meets on the second Wednesday of the month.
• Wetlands and slopes: Carmel requires an Environmental Conservation Board permit within 100 feet of a wetland, and Kent’s controlled area also reaches 100 feet; Nelsonville charges $500 plus escrow for a wetlands or steep-slope permit.
• Septic and well: the Health Department construction permit, valid for two years.
• County road: the DPW permit, issued only after its engineers have inspected the site.
• Flood zones: all nine municipalities take part in the National Flood Insurance Program, so local floodplain rules apply on mapped flood land.

Building permit fees in Putnam County

There is no county building fee. Each town and village adopts its own schedule; for Philipstown and Putnam Valley, ask the building office for the current figure.

For a $40,000 residential renovation, Cold Spring’s rule gives 1% of cost, or $400, plus the $90 certificate fee, a total of $490. In Nelsonville the permit fee for the same job is 40 times $10, or $400.

County charges are separate from the building fee. Health review of a renovation or addition costs $100, a septic repair permit $150 by bank or certified check, and the county road permit carries a fee plus a refundable security whose amount DPW sets after reviewing the work; road permit fees and securities are paid by certified or bank check to the Commissioner of Finance.

Trade permits and who may pull them

Putnam is one of the counties that license trades themselves. The Electrical Board licenses master, special and reciprocal electricians, journeymen, helpers and limited data-communication technicians, and masters and journeymen must take a continuing-education class every year before renewing. The Plumbing/Mechanical Trades Board licenses plumbing, heating and HVAC work, well drillers, pump installers, water-treatment installers and LP-gas installers across the county; since December 9, 2022 it no longer grants new reciprocal licenses to Rockland County licensees. Contractors working on homes must hold a Home Improvement registration, which requires insurance, a bond and workers’ compensation coverage. Septic installers must be registered with both the Health Department and Consumer Affairs, though Health will issue a repair permit to an owner who can do the work.

Electrical permits follow a split the county spells out: in Carmel, Patterson and Putnam Valley they are filed with the town building department, and in Kent, Philipstown, Southeast, Brewster, Cold Spring and Nelsonville with Consumer Affairs. The county names two inspection agencies, State Wide Inspection Services in Fishkill and New York Electrical Inspection Services in Tarrytown.

How to get a building permit in Putnam County

Review, corrections and what causes delay

Local review times vary: Kent quotes 14 to 21 days and Patterson about 7 to 10 business days. Most delays start outside the building office: plans without the Health stamp, a bedroom count that no longer matches the original certificate of occupancy, a room the Health Department treats as a potential bedroom (an office or den upstairs, or a basement room next to a full bath), a contractor without a county license, or a missing referral to the county planners.

Inspections and certificates

The issuing town or village inspects the building work. The Health Department inspects a repaired septic system before it is backfilled, and the electrical agency inspects wiring and sends its certificate on. After the final inspection the local office issues a certificate of occupancy or compliance; Cold Spring charges $90 for it, and Nelsonville gives permits two years to finish the work. On a county road, DPW returns the security once the work is completed satisfactorily.

New York building code

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

Putnam County permit FAQ

Does Putnam County issue building permits?

No. The six towns and three villages issue them; the county approves septic systems, wells and bedroom counts, licenses the trades and permits work on county roads.

Where do I file an electrical permit in Putnam County?

With the town building department in Carmel, Patterson or Putnam Valley, and with the Office of Consumer Affairs for Kent, Philipstown, Southeast and the villages of Brewster, Cold Spring and Nelsonville.

Do I need Health Department approval to renovate?

Yes, if the work changes the floor plan or an addition increases living space. The review costs $100, checks the potential bedroom count against the original approval, and usually takes less than a week.

Who permits a house in the Village of Brewster?

The Village of Brewster, on its own building permit application at Village Hall, 50 Main Street. The Town of Southeast office on the same street covers only land outside the village.

Does a contractor need a county license?

Yes for home-improvement contractors, electricians and plumbing or mechanical trades; each has a county board, and Cold Spring asks for the license numbers with the application.

How does septic review work in the New York City watershed?

Septic applications from the watershed still go only to the county Health Department, which decides whether the city’s Department of Environmental Protection reviews jointly and issues one approval.

How do I get records for an old permit or well?

Ask the issuing town or village; Putnam Valley, for example, pulls building files between 10 a.m. and 2 p.m. and takes copy requests through a FOIL request to the Town Clerk. Well details can be found by tax map number in the County Clerk’s public access portal.
