Building permits, zoning and septic rules in Montgomery County, New York

#39 of 62 in New York

Building permits in Montgomery County, New York come from the town, village or city where the parcel sits, not from the county1,2. Zoning is also local, because Montgomery County does not impose county-level zoning3. Septic approval is a separate track: we could not confirm which health authority approves an ordinary residential septic system, so ask the municipal code office and the health department with jurisdiction4.

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

Yes.

Yes. Work that must comply with New York's Uniform Code or Energy Code requires a building permit from the local authority having jurisdiction2. In Montgomery County, the municipality where the parcel lies administers that requirement1. Installation, alteration or repair of a manufactured home specifically requires a permit from the applicable local municipality7. The 2025 New York Uniform Code became fully effective on December 31, 2025, although the provisions prohibiting fossil-fuel equipment and building systems in new buildings remain suspended by court order and cannot currently be enforced7. A local code program may exempt listed minor work, including a qualifying one-story detached shed or playhouse no larger than 144 square feet, but exempt work must still comply with the codes2. Permitted work is inspected during construction, and any permit-covered work requires a certificate of occupancy or compliance7,9.

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

There is no single county building department for Montgomery County parcels; each town, village or city administers building permits and code enforcement for its own land.

There is no single county building department for Montgomery County parcels; each town, village or city administers building permits and code enforcement for its own land1,3. First identify the municipality containing the parcel, then ask its code-enforcement office. The Montgomery County Real Property Tax Service Agency provides parcel data, tax maps, tax rolls and assessment records that can help identify the municipality10. As a concrete example, the Town of Mohawk Building and Code Enforcement office accepts applications to construct, alter, use or occupy a building or land and issues building permits to applicants who comply with the building codes11. The Mohawk contact applies only to land in that town; owners elsewhere should contact their own municipality3. Septic approval and driveway permits are separate from the building permit and are covered below.

Does Montgomery County have zoning?

Montgomery County does not have county-level zoning; zoning and code enforcement are handled by the town, village or city.

Montgomery County does not have county-level zoning; zoning and code enforcement are handled by the town, village or city3. A parcel's permitted uses, setbacks, minimum lot size and accessory-building rules therefore need a municipal answer rather than a countywide one3. The Town of Mohawk shows how detailed that can get: its zoning law divides the town into districts and sets lot area, yards, coverage and height by district in a schedule8. Mohawk's Zoning Enforcement office reviews residential zoning-use permit applications for compliance with town regulations, and applies only to Mohawk parcels12. We could not confirm district schedules for the county's other municipalities, so obtain the zoning map and dimensional table from the municipality before relying on a listing. Subdivision plats outside incorporated villages go through the town's local process where a town board has authorized planning-board review13.

How do septic permits work in Montgomery County?

We could not confirm which local or district health authority approves an ordinary residential septic system in Montgomery County, so ask the code-enforcement office for the parcel's municipality who must approve the design.

We could not confirm which local or district health authority approves an ordinary residential septic system in Montgomery County, so ask the code-enforcement office for the parcel's municipality who must approve the design. New residential systems must meet New York's statewide Appendix 75-A standards, and an alternative system needs plan approval from the State or county health department official with jurisdiction before construction5. New York does not require a state SPDES discharge permit when a system sends less than 1,000 gallons per day of sewage wastewater to groundwater and contains no industrial or other non-sewage waste, but that does not remove possible approval by a city health department, county health department or New York State Department of Health district office4. Only about 11% of Montgomery County soils are rated without severe limitations for a conventional drain field, so make a site evaluation an early contingency14.

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

We could not confirm a countywide rule allowing or prohibiting occupancy of an RV or tiny home in Montgomery County, because the county does not administer zoning.

We could not confirm a countywide rule allowing or prohibiting occupancy of an RV or tiny home in Montgomery County, because the county does not administer zoning3. Municipal rules can be strict: in the Town of Mohawk, travel trailers are not permanent dwelling units, residency in a trailer camp is limited to 180 days a year, and occupancy outside a court or camp beyond 30 days needs a temporary certificate of occupancy from the Zoning Board of Appeals after inspection and a public hearing8. Mohawk also bars mobile homes from its R-2 Residential District and requires evidence of approved water and sewage systems with a mobile-home permit application8. Ask your own municipality whether the use is allowed and whether an RV may be occupied during construction. A tiny home used as a dwelling must also follow the building-permit process for work subject to the Uniform Code or Energy Code2.

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

Use the Montgomery County Real Property Tax Service Agency's parcel resources to confirm the parcel and its municipality before closing.

  1. Use the Montgomery County Real Property Tax Service Agency's parcel resources to confirm the parcel and its municipality before closing10.
  2. Get the municipal zoning map and dimensional rules, because Montgomery County does not administer zoning3.
  3. Ask the municipality's code office which building permit, fees and construction documents apply; the application must at least describe the work, give the tax-map number and street address, and include construction documents11,15.
  4. Ask the code office who approves the septic design, then make septic approval and a satisfactory site evaluation purchase contingencies4.
  5. Ask the road owner whether a driveway permit is needed: a residence on a State highway needs a NYS Department of Transportation permit16, and Montgomery County Public Works is the contact for county highways17.
  6. Keep work accessible for required inspections and obtain a certificate of occupancy or compliance for any permit-covered work7,9.

What to check before you buy land in Montgomery County

Soils are the first practical constraint: only about 11% of Montgomery County land is rated without severe limitations for a conventional septic drain field.

Soils are the first practical constraint: only about 11% of Montgomery County land is rated without severe limitations for a conventional septic drain field14. About 87% of county land has a slope of 15% or less, but a parcel-specific site evaluation is still necessary14. If the parcel lies in a FEMA-mapped flood hazard area, private development needs a local floodplain development permit, usually handled by the building inspector or code enforcement official18. Confirm whether frontage is on a town, county or state road before asking the road owner about driveway approval17. Montgomery County's effective property-tax rate is about 2.6%, and the median annual property-tax bill is about $3,630, so verify the actual parcel record with Real Property Tax Service10,14. Farmland value averages about $3,700 per acre, which is no substitute for parcel-specific comparable sales14.

Watch-outs

  • Building permits and zoning approval come from the municipality containing the parcel, while septic approval follows a separate health-authority track, so identify the town, village or city before applying1,3,4.
  • We could not confirm whether Montgomery County has an owner-builder exemption from licensed-contractor requirements; ask your town's building and code office directly6.
  • Search results for "Montgomery County building department" can return other Montgomery Counties (Pennsylvania, Maryland, Ohio, Kansas, Texas and more); confirm you are on a montgomerycountyny.gov page or a Montgomery County, NY town's own site, such as the Town of Mohawk's, before calling a number11.

    Publication and adoption of zoning districts by New York municipalities statewide; zoning is locally adopted and administered rather than administered by New York State as a single statewide zoning map.

    • Zoning districts are shown on each municipality’s zoning map.
    • A New York municipality has the choice whether to adopt zoning and, if adopted, how the zoning regulations will work in the community.
    • The source states that all New York cities have adopted zoning, while towns and villages may adopt zoning under the applicable enabling laws and local procedures.
    • District-specific zoning regulations and maps must therefore be obtained from the relevant city, town, or village.

    • For matters the Uniform Code does not provide, Executive Law § 379 permits a municipality to adopt building regulations; local land-use approval therefore requires jurisdiction-specific research.
    “Homes installed after 1/1/06, either new or relocated (even within the same park or community), get a building permit and an installers warranty seal.”
    One more reviewed finding on this topic
    • Limited — Installation and occupancy of manufactured homes in New York

    • The exemption does not eliminate possible approval requirements from the appropriate city health department, county health department, or district office of the New York State Department of Health before construction.
    • Other DEC permits or approvals from other agencies may also be required.

    groundwater discharge design flow: < 1000 gallons per day (Sewage-wastewater containing no industrial or other non-sewage wastes)
