Do you need a building permit in Monroe County, New York?
Building work in Monroe County that must comply with the New York State Uniform Code or Energy Code generally requires a permit administered through the local code-enforcement program12. A city, town or village may exclude listed work, including certain one-story detached sheds, playhouses and similar structures of 144 square feet or less, but excluded work still must meet the codes1. Ask the municipality before treating a small project as exempt because the local authority may require permits for all code-regulated work1. Applications submitted from December 31, 2025 onward must comply with the 2025 NYS Uniform Code9. Permitted construction must remain accessible until inspected and accepted, and permitted work requires a certificate of occupancy or compliance before use108.
Who issues building permits in Monroe County, and how do you reach them?
The city, town or village containing the parcel runs the code-enforcement program and is the first stop for a Monroe County building permit29. The Town of Brighton Building and Planning Department is a useful example, but it serves Brighton only; its office is at 680 Westfall Road, Rochester, and its phone number is 585-784-525011. Brighton directs applicants to its building-permit applications and also publishes separate routes for planning, zoning appeals, architectural review, historic preservation, sign review and certificates of compliance12. Brighton publishes building/occupancy and zoning/planning fee schedules, but those town-specific fees should not be used to price a project elsewhere in Monroe County13. Identify the parcel's municipality, then request that municipality's application, fee schedule, inspection sequence and required zoning approvals.
Does Monroe County have zoning?
Zoning in Monroe County is municipal, so the parcel's city, town or village determines allowed uses, setbacks, lot coverage, building height and whether a proposed dwelling fits the district3. We could not confirm one countywide schedule for those standards, a countywide minimum home size or a countywide minimum lot size; ask the local planning or building office before relying on a listing description. Monroe County has an advisory role for some referred land-use and subdivision actions, but the municipality retains the underlying decision5. County advisory review applies within one-quarter mile of Lake Ontario or Irondequoit Bay and in the named 100-year floodplains, so a parcel in one of those areas may add county review without shifting final local authority14. Subdivision lots using private sewage disposal also face county sanitary-code review5.
How do septic permits work in Monroe County?
The Monroe County Department of Public Health administers onsite wastewater systems and private sewage disposal under the county Sanitary Code4. Contact the Bureau of Public Health Engineering at 111 Westfall Road, Room 844, Rochester, or 585-753-506015. A county representative must inspect a new or repaired system before any part is backfilled, and the county says the inspection will be completed within 48 hours of the request; satisfactory work receives a certificate of approval6. A private system cannot be constructed, repaired or altered where a public sanitary sewer is available and accessible, apart from a temporary construction privy16. Only 11.4% of county soils lack severe limits for a conventional drain field, so make system feasibility part of the purchase investigation17. A qualifying discharge below 1,000 gallons per day may avoid a state SPDES permit, but that does not replace county approval184.
Can you live in an RV or tiny home on your land in Monroe County?
We could not confirm a countywide rule allowing residential or long-term RV use, temporary camping or tiny-home occupancy in Monroe County. Because zoning is municipal, ask the parcel's city, town or village whether its zoning district allows the proposed unit, where it may sit, and whether temporary occupancy during construction is permitted3. A tiny house used as a dwelling may also trigger the local building-permit process when its work must conform to the state building or energy code1. Permission to occupy work covered by a building permit, or a structure converted to another occupancy classification, requires a certificate of occupancy or compliance8. Do not assume that wheels, a small footprint or owner occupancy creates an exemption; we could not confirm a countywide owner-builder exemption or minimum dwelling-size rule.
Building a home in Monroe County: the steps, in order
- Identify the parcel's city, town or village; that municipality administers building permits and zoning23.
- Ask the local office to confirm allowed use, setbacks, site-plan or subdivision review, application documents and the local fee schedule123.
- Check whether shoreline or floodplain location triggers Monroe County's advisory review and whether a subdivision using private sewage disposal needs county sanitary review145.
- Submit the building application to the municipality under the 2025 NYS Uniform Code9.
- For onsite wastewater, work with the county Health Department and first determine whether an available public sewer prevents use of a private system416.
- Leave permitted work exposed for municipal inspections and leave septic work uncovered for the county inspection106.
- Obtain the required certificate of occupancy or compliance before using permitted work8.
What to check before you buy land in Monroe County
Before buying, confirm the municipality and zoning district, because land-use standards and permit administration are local32. Determine whether public sanitary sewer is available and accessible; if it is, Monroe County does not allow a new, repaired or altered private sewage system except for a temporary construction privy16. If septic is necessary, investigate the lot rather than relying on county averages because only 11.4% of county soils lack severe limits for a conventional drain field17. Check county advisory-review maps if the land is near Lake Ontario, Irondequoit Bay or a named floodplain14. Also confirm legal road access and any driveway approval with the road owner because we could not confirm one countywide driveway rule. For carrying costs, the effective property-tax rate is about 2.8% and the median annual bill is about $5,4951920.
Watch-outs
- Brighton's application process and fee schedules apply only in Brighton; obtain the process and current fees from the municipality containing your parcel1213.
- Do not backfill a new or repaired septic installation before the Monroe County health inspection authorizes it6.
- County planning review near specified shorelines and floodplains is advisory and does not replace the municipality's own approval145.
