Zoning, building permits and septic rules in the Town of Bristol, New York

The Town of Bristol, in Ontario County, New York, requires a building permit for any work that must meet the state Uniform Code1, and the town sets its own zoning2. Both go through the town's Code Enforcement / Zoning Office3. Septic rules inside Bristol are not confirmed; the NYS Department of Health Geneva District Office is the environmental-health enforcer for Ontario County4.

Do you need a building permit in the Town of Bristol, NY?

Yes. The Town of Bristol requires a building permit for any work that must conform to the Uniform Code or Energy Code, including construction, additions, alterations, removal and demolition of a building or structure1. The town's code makes exceptions in its Subsection B, which we have not been able to read in full, so ask before assuming a small shed or repair is exempt1. New York lets each town exempt small categories of work, such as a one-story detached shed of 144 square feet or less, but an exemption never excuses code violations8.

When the work is finished, Bristol requires a certificate of occupancy or certificate of compliance6, and the Code Enforcement Officer inspects the work before issuing it9. Permit fees are set by Town Board resolution, so ask the Code Enforcement / Zoning Office for the current schedule10.

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

The Town of Bristol issues its own building permits through its Code Enforcement / Zoning Office, which also handles certificates of occupancy, special use permits, subdivision applications and floodplain development permits3. Ontario County does not issue them: in this county the enforcing authority is the city, town or village11. The office works by appointment only, so call (585) 229-2440 or email [email protected] before you visit3.

The office asks applicants who are unsure what they need to call or email a code or zoning officer before applying3. Applications are reviewed for compliance with the Uniform Code and Energy Code12.

Does Bristol, NY have zoning, and what does it mean for setbacks and lot size?

Yes. The Town of Bristol has its own zoning, and no structure may be built, altered or moved in town unless it conforms to the rules for its district2. Ontario County has no zoning of its own, so the town is the authority for land inside Bristol5.

Setbacks, minimum building size and lot size depend on the district, so check your parcel's district before you buy13. The town's code shows a 35 foot building height limit and 5% maximum lot coverage, both subject to district exceptions1415. Accessory dwelling units are allowed in residential districts with a special use permit from the Zoning Board of Appeals, one per parcel, and not on parcels with two-family or multifamily housing7. Dividing land in violation of the town's subdivision rules makes the division invalid16.

How do septic permits work in the Town of Bristol?

We could not confirm Bristol's own septic permit or inspection rule, so treat septic as a question to settle before closing4. Ontario County describes the NYS Department of Health Geneva District Office as the primary enforcement body for environmental health in the county, reachable at 315-789-30304. For alternative systems, state rules require the State or county health department official to approve plans before construction17.

Soil matters too: about 12.5% of soils in Ontario County rate as not limited for a conventional septic drain field, so most lots need a site evaluation and some need an engineered system18. Private wells inside Bristol are also unconfirmed; ask the same office.

Can you live in an RV or tiny home on your land in Bristol, NY?

We could not confirm any Bristol rule on RV occupancy, temporary camping or tiny homes, so do not assume any of them is allowed. Bristol's zoning governs structures by district19, and the Code Enforcement / Zoning Office also handles temporary use permits3. Call (585) 229-2440 before moving anything onto a parcel3.

State campground limits do not answer this question; they apply only to state-run campgrounds20.

Building a home in Bristol, NY: the steps, in order

  1. Call or email the Code Enforcement / Zoning Office to confirm your parcel's zoning district and what you need3.
  2. Ask the NYS Department of Health Geneva District Office about septic and well requirements for the lot4.
  3. Check driveway access: Bristol requires driveways to sit at least 10 feet from a property line, with approval from the highway department having jurisdiction21. A driveway onto a county road needs a county highway permit22, and a residence on a state highway needs a NYSDOT permit23.
  4. Apply for a building permit from the town1.
  5. Have work inspected, then obtain the certificate of occupancy6.

What stays with Ontario County, and what to check before you buy in Bristol?

Bristol decides zoning and building permits for land inside town; for land elsewhere in the county, see the Ontario County page. Ontario County's Planning Board reviews some subdivisions within 500 feet of listed boundaries, parks, highways and similar features, but its action is advisory and the local board decides24.

The next checks are zoning district, septic, driveway access and taxes. Ontario County's effective property tax rate is 2.2%25, with a median bill of $4,460 a year26. Floodplain development permits are handled by the town office, so ask about any parcel near water3.

Watch-outs

  • The Code Enforcement / Zoning Office works by appointment only, so call or email before visiting3.
  • The Town of Bristol is not the same as the Town of South Bristol, also in Ontario County; confirm which town's office you are dealing with3.
