Building permits, zoning and septic rules in Sullivan County, New York
64Index Score / 100 #19 of 62 in New York
In Sullivan County, New York, building permits are issued by the city, town or village where the parcel sits, under the statewide Uniform Code1. Zoning is also set town by town, not by the county23. Septic approval stays with the health department or NYSDOH, plus NYC DEP review in the New York City watershed, whichever municipality the parcel is in4.

Do you need a building permit in Sullivan County, New York?
Yes. In Sullivan County, work covered by the New York State Uniform Code requires a building permit, subject to limited exceptions, and the local city, town or village generally administers the requirement1. The 2025 Uniform Code has applied since December 31, 2025, and legally authorized local standards may be more restrictive14. A local authority may exempt listed minor work, including a qualifying one-story detached shed, playhouse or similar accessory structure no larger than 144 square feet, but exempt work must still comply with the codes15. Bethel illustrates the local detail: its Building Inspector issues permits for structural construction, including new homes, additions, garages and sheds over 144 square feet16. Specified construction elements must be inspected, and permitted work must remain accessible until accepted17. A certificate of occupancy or compliance is required for work that needed a permit and when the general occupancy classification changes18.
Who issues building permits and zoning approval in Sullivan County, and how do you reach them?
Building permits in Sullivan County are generally administered by the city, town or village with jurisdiction under the statewide Uniform Code1. Sullivan County contains 15 towns, 7 villages and more than 30 hamlets, so identify the parcel's municipality before looking for an application or fee schedule; septic approval does not move to the town, because it runs through the health department or NYSDOH196. The county Planning Division assists municipalities with land-use policy but does not identify itself as the building-permit office19. In Thompson, the Building, Planning & Zoning Department reviews plans, issues permits and certificates of occupancy, and can be reached at (845) 794-2500 ext. 32120. Thompson publishes a permit guide, application, owner-proxy form, electrical-inspector information and residential fee schedule21. Online credit-card payments in Thompson carry a 2.65% processor fee with a $1.50 minimum charge22. Its application also calls for a site plan, construction plans, insurance documentation, applicable board approvals and any required water or sewer district approval before work begins2324.
Does Sullivan County have zoning?
New York law gives general zoning power to cities, towns and villages, not counties, so Sullivan County does not supply one zoning code for every parcel2. The Town of Thompson, for example, administers its own building, zoning and land-use rules25. Thompson requires a building-permit site plan to show setbacks from every property line and existing structure, although the application does not give the actual distances26. Municipal planning approval may also matter when land is divided: the Mamakating Planning Board had subdivision jurisdiction over the portion of one reviewed project within Mamakating, but that project-specific finding does not establish the rule elsewhere27. Dimensional rules differ sharply by town. In the Town of Fallsburg's Residence District R, a one-family house without public sewer and water needs at least 3 acres and 1,200 square feet of floor area, with coverage capped at 10 percent, while a lot with public sewer and water needs half an acre2829. We could not confirm one rule across all municipalities for RV occupancy, tiny homes, minimum dwelling size, lot size, setbacks, lot coverage or building height. Ask the town or village zoning office for the parcel's district, use table and dimensional schedule before making an offer. The Sullivan County Planning Division can assist with land-use information and municipal contacts19.
How do septic permits work in Sullivan County?
For an individual septic system in Sullivan County, NYSDOH directs applicants to the local health department or NYSDOH, while NYC DEP review may also apply in the New York City watershed4. NYSDOH district offices or county health departments must approve wastewater-disposal plans before construction, and DEC may have concurrent jurisdiction6. A residential system receiving less than 1,000 gallons per day falls under Appendix 75-A, and a design that departs from those standards needs a Specific Waiver from the State Commissioner of Health or the designated full-time local health official30. A qualifying discharge of ordinary sewage below 1,000 gallons per day does not need a state SPDES permit, but health-department approval and other approvals may still apply31. Only 0.6% of Sullivan County land has soil without severe limitations for a conventional drain field, so establish septic feasibility before fixing a house location9. Sullivan County Public Health can connect callers to the right program32. We could not confirm which office processes every ordinary residential application outside the watershed.
Can you live in an RV or tiny home on your land in Sullivan County?
We could not confirm one countywide rule allowing or banning RV or tiny-home living in Sullivan County; zoning is administered town by town5. A certificate of occupancy or compliance is required for work that needed a building permit and when the general occupancy classification changes33. Manufactured-home installation, alteration and repair require a building permit, a certified installer and occupancy approval, while local zoning may impose stricter standards13. A tiny house built to the Residential Code of New York State and its Appendix BB is exempt from the Property Maintenance Code's occupancy limits, but building permits, local zoning and septic requirements still apply34. Those manufactured-home rules do not answer whether a municipality allows a tiny home or residential RV on a particular lot. Ask the parcel's town or village about the proposed structure and use before buying; in Thompson, contact the Building, Planning & Zoning Department at (845) 794-2500 ext. 32120.
How do you build a home in Sullivan County, step by step?
Identify the city, town or village with jurisdiction, because the local authority generally administers building permits and municipal zoning determines the application path12.
Confirm the zoning district and proposed use with that municipality before commissioning plans5.
Establish septic feasibility early: only 0.6% of county soils have no severe conventional-drain-field limitation, and the review path depends on location94. In Bethel, wells and septic systems appear among the work handled through the Building Inspector's permit process1016.
Submit the work location, tax map number, scope, occupancy classification and acceptable construction documents to the local permit authority35. Thompson publishes its own permit materials and requires the listed local documents and approvals before work begins2123.
Keep permitted work accessible and exposed until required construction inspections are accepted3637.
Obtain the certificate of occupancy or compliance before using work that required a permit38.
For a new or relocated driveway on a county road, contact Sullivan County Public Works at (845) 807-0283 for the Road Access Application39.
What should you check before you buy land in Sullivan County?
Confirm septic feasibility first: only 0.6% of Sullivan County soil has no severe limitations for a conventional drain field9. For a watershed parcel, ask NYC DEP whether septic review or a regulated sewer connection applies in addition to other agency permits740. We could not confirm one countywide floodplain-development process, so ask the municipal building office which floodplain review applies. Determine who maintains the frontage road: Sullivan County has county, state, town and private roads, and County Public Works supplies access applications for new or relocated driveways on county roads39. A reviewed large development needed county road-access permits and separate town access approvals, showing why the road authority and project scope both matter; that finding does not establish a permit requirement for every driveway41. If land is being divided, New York's realty-subdivision rule can cover the tract when a fifth residential lot is offered within three years of the first offering, including the previously sold lots42. Sullivan County's effective property-tax rate is about 2.2%, with a median annual bill near $5,0821112.
Watch-outs
New York does not require a state home-improvement-contractor license for an owner doing work at a primary residence, but this does not waive building permits, inspections or local trade-license rules43.
If your land is in the New York City water supply watershed, NYC DEP review is required for projects meeting its regulatory criteria and may be separate from other permits7.
Zoning, RV and tiny-home rules are set by your specific Sullivan County town, not the county government — confirm with that town before you buy or place a structure5.
Written October 9, 2026 from the rules quoted below, each taken from an official source and re-checked by an independent reviewer. This is research, not legal advice: rules change, so confirm with the office before you buy or build.

Who permits septicMixed (with conditions)
Individual onsite wastewater systems serving property in Sullivan County.
The New York State Department of Health provides statewide residential onsite-wastewater standards and guidance.
The official NYSDOH page directs applicants to contact the local health department or NYSDOH, so the precise local office and any additional local requirements must be confirmed for the parcel.
NYC DEP review or approval may additionally apply in the New York City watershed.
“Contact your local health department or the New York State Department of Health”
Septic permitLimited
Sewage-wastewater discharges to groundwater in Sullivan County with design flow below 1,000 gallons per day and no industrial or other non-sewage wastes.
No SPDES permit is required for the stated below-1,000-gpd category.
Health-department approval may still be required before a septic system or cesspool is built.
Other DEC permits or approvals may also be required.
design flow: < 1000 gallons per day (no industrial or other non-sewage wastes)
“No SPDES permit is required for a facility whose treatment system has a design flow [...] of less than 1,000 gallons per day”

Mandatory utility hookupConditional
Connection to an existing sewer system with a service lateral within the New York City watershed portion of Sullivan County.
The NYC DEP watershed rules list connection to an existing sewer system with a service lateral as a regulated activity.
DEP review and approval and any applicable local, City, State, or federal permit may be required.
“Connection to an existing sewer system with a service lateral;”
Driveway accessRequired
Road access for the identified large-scale development project in Sullivan County.
The finding is project-specific and does not establish a countywide driveway standard.
The source separately states that the Town of Fallsburg would also need to issue road access approvals for the project portion there.
“Sullivan County Department of Public Works will need to issue road access permits.”
County-wide zoningPresent
Zoning is adopted and administered at the town/village level, not countywide; for example the Town of Thompson has Chapter 250 Zoning.
Work that must conform to the New York State Uniform Code or Energy Code throughout New York State except New York City, where the city has its own construction code; local authorities having jurisdiction administer and enforce the state requirements within their boundaries.
A local authority having jurisdiction may expressly exempt one or more listed categories of work from the building-permit requirement.
Permitted exemption categories include one-story detached tool or storage sheds, playhouses, or similar structures associated with one- or two-family dwellings or townhouses not exceeding 144 square feet gross floor area; temporary sets and scenery; certain window awnings; partitions or movable cases less than 5 feet 9 inches high; painting, wallpapering, tiling, carpeting, or similar finish work; listed portable equipment or appliances; certain equipment replacements; and repairs that do not affect fire and life safety.
A permit exemption does not authorize work violating the Uniform Code or Energy Code.
Beginning December 31, 2025, regulated parties submitting building permit applications must comply with the 2025 NYS Uniform Code, subject to the stated transition option before that date.
maximum gross floor area for listed detached accessory structures: <= 144 square feet (Only for one-story detached structures associated with one- or two-family dwellings or townhouses and used for tool/storage sheds, playhouses, or similar uses.) · height threshold for listed partitions or movable cases: < 5 feet 9 inches
“Each authority having jurisdiction shall include in its code enforcement program provisions requiring building permits to be required for work that must conform to either or both of the Codes.”

Required — Work in Sullivan County required to conform to the New York State Uniform Code.
“Building permits must be required for any work which is required to conform to the Uniform Code. Certain exceptions are permitted.”
Required — Work in Sullivan County that is required to conform to the New York State Uniform Fire Prevention and Building Code.
“The Uniform Code, which took effect on January 1, 1984, prescribes the minimum standards for building construction in New York. It is applicable in every part of the State with the exception of New York City, which is currently permitted to retain its own code.”
Owner-builder exemptionConditional
Owner-performed home-improvement work at an owner’s primary residence in New York, as to a New York State home-improvement-contractor license.
New York State does not license home-improvement contractors.
A county or local municipality may license home-improvement contractors or particular home-improvement trades.
The Department of State identifies New York City; Suffolk, Nassau, Westchester, Putnam, and Rockland Counties; and the City of Buffalo as examples of local jurisdictions requiring a home-improvement-contractor license.
This finding concerns home-improvement-contractor licensing only; it does not establish an exemption from locally administered building permits, inspections, or licenses for particular trades.
“Check your local government licensing requirements: New York State does not license home improvement contractors. However, some counties and local municipalities do, including New York City, Suffolk, Nassau, Westchester, Putnam, and Rockland counties, and the City of Buffalo.”
Building code adoptedAdopted
The New York State Uniform Fire Prevention and Building Code for construction statewide outside New York City, including residential construction in towns and other local governments.
The Uniform Code took effect January 1, 1984.

Zoning districtsPartial
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.
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.”
One more reviewed finding on this topic
Partial — New York cities, towns, and villages that enact local zoning laws and zoning districts
“New York’s zoning enabling statutes (the state statutes which give cities, towns and villages the power to enact local zoning laws) require that zoning laws be adopted in accordance with a comprehensive plan.”
Tiny homesAllowed (with conditions)
Tiny houses in Sullivan County governed by the New York State Uniform Code.
The tiny house must be constructed in accordance with the Residential Code of New York State and Appendix BB.
The provision addresses exemption from the Property Maintenance Code Section 404 occupancy limitations; it does not eliminate applicable building permits, local zoning, septic, or other health requirements.
The 2025 NYS Uniform Code became effective December 31, 2025; during the transition period, compliance with either the 2025 or 2020 Uniform Code was permitted.
“The provisions of Section 404 shall not apply to tiny houses constructed in accordance with [...] Appendix BB of the Residential Code of New York State.”
Manufactured homesLimited
Installation, alteration, and repair of manufactured homes in Sullivan County.
A building permit is required for work subject to the Uniform Code, including specified manufactured-home installation, alteration, and repair.
A certificate of occupancy or compliance is required for work subject to a building permit.

Local zoning or other local laws may impose approved more restrictive standards.
“Are permits and certificates of occupancy/compliance required for the installation of a manufactured home? Yes.”
Septic inspectionLimited
Post-construction certification for residential alternative onsite wastewater treatment systems under Appendix 75-A.
A design professional must supervise construction.
The design professional must certify after construction that supervision occurred and that construction conforms to approved plans.
The cited passage establishes certification, not a general periodic inspection schedule for routine operation.
“a design professional shall provide [...] a certification”
Off-grid sanitationAllowed (with conditions)
Use of an individual onsite wastewater treatment system where a municipal or communal wastewater system is unavailable.
The system must comply with statewide Appendix 75-A minimum standards.
Alternative systems require prior review and approval by the State or county health department official having jurisdiction.
Design must be prepared by or under the supervision of a design professional.
“when a municipal or communal system is not available”
Agricultural exemptionConditional
Farm operations located within a New York agricultural district, including associated land, on-farm buildings, equipment, manure processing and handling facilities, and qualifying agricultural practices.
The protection applies only to farm operations in an agricultural district.
Local governments must exercise their planning and land-use authority consistently with Article 25-AA of the Agriculture and Markets Law.
Local governments may not unreasonably restrict or regulate the covered farm operation unless public health or safety is threatened.
Only farm operations are protected; the Department evaluates whether the regulated activity encompasses a farm operation.
The reasonableness analysis considers whether the restriction is unreasonable on its face and as applied to the particular situation, and depends on the totality of the circumstances.
A farmer, municipality, or other eligible requester may seek a Department opinion concerning the effect of a proposed or existing local law or ordinance.
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.”

Conditional — Farm operations within New York agricultural districts seeking protection from unreasonable local planning, zoning, land-use, or permitting restrictions.
“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.”
Available (with conditions) — Agricultural uses and agricultural-use structures within the Adirondack Park Agency jurisdiction, including relevant Freshwater Wetlands Act and Wild, Scenic and Recreational Rivers System Act permitting contexts.
““Agricultural uses” and “agricultural use structures” are generally exempted from permitting requirements under New York State’s Adirondack Park Agency Act”
Subdividing landLimited
Subdivision review by a town planning board for land outside the limits of an incorporated village in New York.
The town board may authorize and empower the planning board only by resolution.
Town Law § 276 applies to the part of a town outside the limits of an incorporated village.
Subdivision means division of a parcel into lots, blocks, or sites as specified in a local ordinance, law, rule, or regulation, with or without streets or highways, for sale, transfer of ownership, or development.
Local regulations may define subdivisions as major or minor and must set the review procedures and criteria for each.
Preliminary and final plats must comply with applicable State Environmental Quality Review Act requirements.
A final plat receiving conditional approval does not qualify for recording and does not authorize building permits until the required conditions are completed, the plat is signed by an authorized planning-board officer, and the plat is recorded.
An approved final plat must generally be filed with the county clerk or register within sixty-two days after final approval or the approval expires.
minimum unimproved-lot threshold for previously filed plat to be treated as undeveloped: >= 20 percent (unless existing conditions, such as poor drainage, have prevented development) · final plat filing deadline after final approval: 62 days (otherwise approval expires) · partial approved plat filing threshold: >= 10 percent of total lots (remaining sections are subject to the statutory expiration rule)
“the town board may, by resolution, authorize and empower the planning board to approve preliminary and final plats of subdivisions showing lots, blocks or sites, with or without streets or highways, within that part of the town outside the limits of any incorporated village.”

Building in a floodplainRequired
Development in FEMA-mapped Special Flood Hazard Areas in New York State, with local administration by the municipality having jurisdiction.
Local communities participating in the National Flood Insurance Program regulate development in Special Flood Hazard Areas.
Private development is subject to local floodplain development permits.
Development funded and undertaken by the State or Federal government is an exception to the local-permit rule and is regulated by the responsible agency, subject to technical assistance by NYSDEC and FEMA.
Each participating community has a designated floodplain administrator, usually the building inspector or code enforcement official.
The local laws apply to development undertaken by any county, city, town, village, school district, or public improvement district within the community.
The source states that any new structure or structure substantially improved or substantially damaged is subject to floodplain development regulations, with substantial improvement or damage exceeding 50% of the structure’s market value.
substantial improvement or damage threshold: > 50 percent of structure market value
“Private development is subject to local floodplain development permits.”
Permit feesVariable (with conditions)
New York State Department of State building-permit administration and enforcement fees.
The schedule is identified as having a publication date of August 2022.
Fees vary by project type, building type, area, dwelling unit, sleeping room, inspection, and permit category.
For one- and two-family homes including accessory structures constructed contemporaneously, the schedule lists $200 for the first 1,500 square feet and $100 for each additional 1,000 square feet or fraction thereof.
Permit renewals have no fee.
Building-permit fees include construction inspections required as a result of the permit; additional inspection fees may apply.
Local authorities may have separate fees or requirements.
publication date: August 2022 · one- and two-family homes fee for first 1,500 square feet: 200 USD (including accessory structures constructed contemporaneously) · one- and two-family homes fee for each additional 1,000 square feet or fraction: per 100 USD (after the first 1,500 square feet) · permit renewal fee: 0 USD

“A list of NYSDOT highway work permit fees can be found here: NYSDOT Permit Fee Matrix”
Permit processPublished (with conditions)
Building-permit applications for work subject to the New York State Uniform Code or Energy Code, administered through the authority having jurisdiction’s code-enforcement program.
A building permit is required for work that must conform to the Uniform Code or Energy Code.
The code-enforcement program may exclude listed categories, including qualifying detached structures not exceeding 144 square feet, temporary sets and scenery, certain awnings, partitions or movable cases under 5 feet 9 inches, finish work, listed portable equipment, qualifying equipment replacements, and repairs that do not affect fire and life safety.
Excluded work must still conform to applicable Uniform Code and Energy Code provisions.

county building authorityLimited
County administration and enforcement of the Uniform Code and Energy Code within a local government, including unincorporated town areas, when the local government has opted out or when the Secretary of State designates the county.
Every local government ordinarily administers and enforces the Uniform Code and Energy Code.
A local government may opt out by local law enacted before July 1; the opt-out becomes effective January 1 of the following year.
After a local-government opt-out, the county administers and enforces the codes within that local government.
The county may itself enact a local law opting out; if both local government and county opt out, the Secretary of State administers and enforces the codes.
Counties may charge fees to defray administration and enforcement costs.
A responsible county must establish a code-enforcement program by local law, ordinance, or other appropriate regulation.
local-government opt-out deadline: < July 1 · successor enforcement date: January 1 (the January 1 next succeeding the effective date of the local law)
“The secretary may designate the county in which such local government is located to administer and enforce the uniform code in such local government.”
