Coverage

Countywide context only. Ontario County does not operate a single countywide private building-permit office for all unincorporated land. Outside New York City, the Uniform Code is generally enforced by the city, town, or village with jurisdiction unless that municipality opts out under Executive Law Section 381. For unincorporated land, the controlling permit authority is ordinarily the town where the parcel sits.
