Do you need a building permit in Putnam County, New York?

Work in Putnam County, New York that must conform to the statewide Uniform Code requires a building permit, with permitted exceptions under the local enforcement program1. The 2025 Uniform Code is now effective in Putnam County11. A qualifying detached structure no larger than 144 square feet may be exempted by the local program, but exempt work must still comply with the Uniform Code and Energy Code12. Required inspections include foundations, slabs, framing, building systems and final inspection where applicable; keep work accessible and exposed until accepted6. Permit work and changes in general occupancy classification require a certificate of occupancy or compliance7. Carmel requires occupancy certificates for completed structures except detached tool sheds and structures built before 1955; wood stoves, fireplaces, generators, HVAC and oil tanks require compliance certificates instead13.

Who issues building permits in Putnam County, and how do you reach them?

The applicable local government generally administers and enforces the Uniform Code in Putnam County; county or state enforcement applies only in specified opt-out circumstances2. Start with the building department for the town or village where the parcel lies because local zoning rules and procedures vary across Putnam County9. A permit application must describe the location, scope and occupancy and include acceptable construction documents; site, structural, building-system, energy and flood information may also be required12. For a Carmel parcel, the Town of Carmel Building Department is at 60 McAlpin Avenue, Mahopac, NY 10541, and the phone number is 845-628-150014. Carmel conducts inspections Monday through Friday from 9:30 am to 1 pm and asks for 2 to 3 days of advance notice14. Whichever town or village issues the building permit, septic and well permits stay with Putnam County Health415.

Does Putnam County have zoning?

Putnam County does not administer a countywide zoning code; towns and villages regulate zoning within their jurisdictions3. Municipal zoning leaves septic and well review with Putnam County Health45. Municipalities take final action after any required County Planning referral and recommendation9. Carmel publishes a zoning map and district schedule that controls buildings, structures and lots, including district-specific yards1617. Carmel’s SMR multifamily dwellings need at least 650 square feet of habitable area18. In Carmel’s HMC district, multifamily dwellings need 650 square feet and single-family attached dwellings need 1,200 square feet; special-use approval and public water and sewer service are also required19. The Carmel Planning Board reviews subdivisions, while applicable county health subdivision review remains a separate requirement2021.

How do septic and well permits work in Putnam County?

Putnam County Health receives septic applications and determines whether watershed projects require joint NYC DEP review4. New systems and repairs require county approval; routine pumping, snaking, line cleaning and sewage-pump replacement do not require prior approval8. Soil test pits or percolation tests for repairs must be witnessed by county engineering staff, and approved repairs must be inspected before backfilling2223. New construction on vacant land requires professional design; county health construction permits last 2 years and may be renewed24. The septic repair permit costs $150, payable by bank or certified check, and Health Department review of house-addition floor plans costs $10025. For septic or sewer approval, call (845) 808-1390 and ask for a Putnam County Health engineer15. Only 8.7% of county soils are rated without severe limits for a conventional drain field, so test feasibility early26.

Can you live in an RV or tiny home on your land in Putnam County?

We could not confirm residential RV or tiny-home occupancy rules for every Putnam County municipality; ask the parcel’s municipal building or zoning office about the proposed use9. Carmel’s recreational-vehicle areas allow transient camping, prohibit permanent living units and bar use as a primary residence; these provisions do not establish permission to live in an RV on an ordinary private parcel27. Carmel accessory dwelling units require at least 400 square feet and may not exceed 35% of the principal dwelling’s habitable floor area; detached ADUs also have a 650-square-foot ceiling28. The owner must live in the principal dwelling or ADU, and building permits and an occupancy certificate are required28. County Health must approve water and sewage arrangements; Town Engineer approval is also required for town water or sewer connections29. Indoor-plumbing wastewater must discharge to an approved septic system30.

Building a home in Putnam County: the steps, in order

  1. Identify the parcel's town or village and obtain its zoning district, permitted-use list and district schedule because Putnam County has no countywide zoning code3.
  2. Ask Putnam County Health whether septic review is county-only or joint with NYC DEP and submit the required septic application48.
  3. Obtain a Putnam County Health permit before drilling a new-home well or re-drilling an existing-home well5.
  4. For a subdivision, obtain applicable municipal and County Health approvals; county health subdivision approvals last 5 years and may be renewed, and a Health-signed map is not valid until filed with the County Clerk21.
  5. Apply to the applicable local building authority for work governed by the Uniform Code1.
  6. Schedule each applicable building inspection and keep the work accessible and exposed until accepted31.
  7. Arrange septic inspections during construction and before backfilling an approved repair3233.
  8. Obtain the required certificate of occupancy or compliance before occupying or using completed permit work7.

What to check before you buy land in Putnam County

Confirm the municipality and zoning district before closing because Putnam County has no countywide zoning code and municipal permitted uses, setbacks and lot standards may apply3. Test septic feasibility early because only 8.7% of county soils are rated without severe limits for a conventional drain field26. Confirm the drinking-water plan because Putnam County Health requires a permit before a new-home well is drilled or an existing-home well is re-drilled5. Check clearing and grading needs because 90.4% of Putnam County is wooded and 67.7% of its land has a slope of 15% or less3435. A driveway built or modified on a state highway requires a New York State Department of Transportation permit36. Private development in a floodplain requires a local floodplain development permit37.

Watch-outs

  • Putnam County has no countywide zoning code; a Carmel rule is not a countywide permission or restriction3.
  • Carmel’s short-term rentals require a special-use permit and Planning Board site-plan approval; tents, campers, RVs, trailers and mobile homes cannot serve as short-term rentals38.
  • An owner-occupant may apply for manufactured-home installer certification, but a certified installer must be on site and supervise and certify homeowner installation work; the building-permit requirement remains10.
  • Carmel’s ADU and district-specific dwelling-size standards do not establish a general tiny-home occupancy permission2819.

    • District-specific zoning regulations and maps must therefore be obtained from the relevant city, town, or village.
    • The cited publication discusses local adoption procedures and does not publish a single statewide set of zoning districts.
    “Since New York is a home rule state, a municipality has the choice of whether or not to adopt zoning and if it does, how the zoning regulations will work in the community.”

    • If the Department determines that a local law or ordinance is unreasonably restrictive, it may seek remediation and the Commissioner may issue an order to comply or bring an enforcement action.
    “Local governments, when exercising their powers to enact and administer comprehensive plans and local laws, ordinances, rules or regulations, shall exercise these powers in such manner as may realize the policy and goals set forth in this article, and shall not unreasonably restrict or regulate farm operations within agricultural districts in contravention of the purposes of this article unless it can be shown that the public health or safety is threatened.”
