Read this before you act on anything below. This is my researched starting point for Oswego 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.

Septic & composting toilets

Greywater reuse
Unclear - verifyNo Oswego County or town page on greywater reuse was found; this is not confirmed locally, so ask the county Health Department directly.
Rainwater harvesting

Private wells & water rights

Living disconnected from utilities
Varies locallyNo county law mandates grid connection, but county septic approval and local building permits are still required for habitable structures, which limits fully unpermitted off-grid living; town rules were not individually confirmed.
