Read this before you act on anything below. This is my researched starting point for Cortland County, NY, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesCortland County, NY

Zoning & raw-land occupancy

Varies locallyCortland County has no countywide zoning ordinance; each town or city (Cortlandville, City of Cortland, Homer, Dryden, Virgil, etc.) enacts and enforces its own zoning chapter, so raw-land occupancy rules depend entirely on the specific municipality. source

Dwellings, tiny homes & RVs

Unclear - verifyNo county-level rule on tiny homes or RVs as dwellings was found; this is set by each town's zoning chapter and the state Uniform Code, so confirm with the specific town's code enforcement office. source

Building permits & codes

RestrictedThere is no county building department; each town or city runs code enforcement under the NYS Uniform Fire Prevention and Building Code, and towns like Cortlandville require permits before erecting or altering structures, with a narrow exemption for very small accessory buildings. source

Septic & composting toilets

RestrictedThe Cortland County Health Department's Environmental Health Division permits septic systems countywide, requiring an engineer's design for new or full-replacement systems, though a tank-only replacement can skip that step. source

Greywater reuse

Unclear - verifyNo Cortland County or town page addresses greywater reuse specifically, so this falls back to the state DOH baseline; not confirmed locally, so ask Environmental Health directly.

Rainwater harvesting

Unclear - verifyNo county-specific rainwater harvesting ordinance was found; it appears to be governed only by state guidance, and it does not appear restricted, but this is not confirmed in writing at the county level.

Private wells & water rights

RestrictedThe Environmental Health Division issues well construction permits and completion certificates countywide, handling around 125 permits a year, and applicants should use the county's Well Application Form. source

Living disconnected from utilities

Varies locallyThere's no countywide law requiring grid connection; whether a dwelling must connect to utilities is set by each town or city's own zoning and code, so this must be confirmed locally. source
