Building permits in Rockland County, New York come from the town or village where the property sits, not from the county1. Zoning also varies by municipality, while County Planning reviews certain referred local actions2. County Health approval and inspection are established for individual sewage systems in approved subdivisions, but we could not confirm a separately named county permit for every septic system3.

Do you need a building permit in Rockland County, New York?
Yes. Building permits in Rockland County are issued by the town or village with jurisdiction over the parcel, not by one county building department1. The 2025 New York State Uniform Code has applied outside New York City since December 31, 20259. In Clarkstown, new construction, renovations, remodeling and other work subject to the Uniform Code or Energy Code require a building permit, with listed exceptions for some ordinary repairs and minor work4. Clarkstown requires a certificate of occupancy for a new building, an alteration, a change in use or occupancy, or work for which a building permit was issued10. Clarkstown issues that certificate only after an inspection finds no uncorrected deficiency or material code violation11.
Who issues building permits in Rockland County, and how do you reach them?
Start with the town or village shown for the parcel, because Rockland County has municipal rather than countywide building-permit administration1. For Clarkstown property, contact the Town of Clarkstown Building Department at 10 Maple Ave., Room 101, New City, NY 10956, or (845) 639-210012. An owner, agent or contractor may apply in Clarkstown, and the application may need a survey plus construction plans or drawings13. Clarkstown checks applications against its building, housing, plumbing, zoning, preservation and other applicable codes13. Clarkstown charges $150 for the first $1,000 of estimated cost, then $18 for each additional $1,000 or part7. Rockland County's online portal handles most county plan reviews and permits, but it does not replace the municipality's building-permit process14.
Does Rockland County have zoning?
Zoning in Rockland County varies by town and village rather than following one countywide district map2. County Planning reviews certain municipal zoning, planning and subdivision actions before the municipality acts, but the municipality remains the local decision-maker2. Clarkstown's Planning Department supports the Planning Board and Zoning Board of Appeals15. Standards vary even within Clarkstown: in the TOD 3 district, lots must be at least 10,000 square feet and 60 feet wide16. TOD 3 studios and one-bedroom units are listed at 500 to 850 square feet, while primary-building setbacks include a front yard of 5 to 15 feet and a rear yard of at least 25 feet1718. Those figures do not apply across Clarkstown or Rockland County; ask the parcel's municipal planning office for its zoning district and current standards.
How do septic permits work in Rockland County?
Rockland County Health approval and inspection are established for individual sewage-disposal facilities in approved realty subdivisions, but the cited rule does not identify a separately named general septic permit for every system3. In that subdivision context, the plan must describe potable water, sewage and drainage facilities, and County Health must inspect individual water-supply and sewage-disposal installations before completion3. The facilities cannot enter service until the Commissioner of Health issues the appropriate approval3. A residential subdivision of three or more qualifying parcels triggers County Health review, including an inspection fee3. Only 4.3% of Rockland County soils rate without severe limitations for conventional drain fields, so make septic feasibility an early contract contingency19. For a parcel outside an approved subdivision, ask Environmental Health at 845-364-2656 exactly which plan approval, inspection and fee requirements apply20.
Can you live in an RV or tiny home on your land in Rockland County?
We could not confirm a countywide rule allowing residential or long-term RV occupancy, temporary camping, or tiny-home occupancy. Zoning varies by town and village, so permission depends on the municipality's use and dimensional rules2. Ask the local planning office whether the proposed unit is treated as a dwelling, accessory structure, manufactured home or recreational vehicle, and whether temporary occupancy during construction is allowed. For Clarkstown land, start with the Town of Clarkstown Planning Department at (845) 639-207015. Clarkstown requires building permits for new construction, renovations, remodeling and other work subject to the Uniform Code or Energy Code, with listed exceptions for some ordinary repairs and minor work4.
Building a home in Rockland County, New York: the steps, in order
- Identify the parcel's town or village, because that municipality handles building permits and zoning12.
- Ask the municipal planning office to confirm the use, setbacks and site-plan or variance needs; Clarkstown's Planning Department supports its land-use boards15.
- Check the flood map and nearby streams; development in a FEMA Special Flood Hazard Area needs a local floodplain permit, while work near a county-regulated stream may also need Drainage Agency review2122.
- Ask County Health whether the parcel's sewage system needs plan approval and inspection; the established county rule covers individual systems in approved subdivisions3.
- Apply to the local building department with the required survey and plans; Clarkstown applications may require both13.
- Keep permitted work available for inspection and obtain the local certificate of occupancy before using the completed home2310.
What to check before you buy land in Rockland County, New York
Confirm the town or village, zoning district, legal access and utility status before making an offer, because building permits and land-use rules are municipal12. Make septic feasibility a contract contingency: only 4.3% of Rockland County soils rate without severe limitations for a conventional drain field19. If a parcel is in an approved subdivision, County Health must inspect individual water-supply and sewage-disposal installations before completion3. Development in a FEMA Special Flood Hazard Area requires a local floodplain permit21. A driveway onto a New York State highway needs a permit from the New York State Department of Transportation24. Work in or near a county-regulated stream needs a Stream Control Act permit from the Drainage Agency, with a $25 application fee and a $125 initial review fee25. We could not confirm countywide private-well or driveway-access rules for other roads, so ask the municipality and Environmental Health. The median property-tax bill is about $10,001 a year, with an effective rate near 1.8%2627.
Watch-outs
- Clarkstown lets an owner-occupant perform basic electrical or plumbing work in a single-family dwelling under stated conditions, but plumbing still needs a building permit when required and this is not a general permit exemption5.
- County septic approval is established for individual systems in approved subdivisions, but we could not confirm a separately named general septic permit for every system; ask Environmental Health before relying on a parcel's existing approval320.
- Living in an RV or tiny home on private land is not confirmed countywide; ask the parcel's town or village planning office before buying or moving a unit onto the site215.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
