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.

The local rulesRensselaer County, NY
Zoning & raw-land occupancy
Varies locallyRensselaer County has no countywide zoning code; every parcel sits inside a town, city, or village that sets its own zoning ordinance, per the county's own FAQ. source
Dwellings, tiny homes & RVs
Unclear - verifyNo county-level rule on tiny homes or RVs as permanent dwellings was found; this is set by each municipality's zoning and building code, so ask your specific town or city. source
Building permits & codes
RestrictedBuilding permits are required for new construction, additions, and work touching structural, electrical, mechanical, or fire-safety systems, including wood stoves, but enforcement is done by each local city, town, or village code office, not the county. source
Septic & composting toilets
RestrictedThe Rensselaer County Department of Health's Public Health Engineering division permits and inspects individual sewage treatment systems under state DEC-aligned standards; a final county inspection is required. source
Greywater reuse
Unclear - verifyNo Rensselaer County or sample municipal page on greywater reuse was found; not confirmed, so ask the county Health Department or your local building office directly.
Rainwater harvesting
Unclear - verifyNo county-specific rainwater harvesting guidance was found; likely follows the general New York baseline of permitting non-potable collection, but not confirmed locally.
Private wells & water rights
Generally allowedThe county's Individual Water Supplies program assists residents but defers to New York State Sanitary Code Appendix 5-B for well construction standards rather than imposing its own separate well code.
Living disconnected from utilities
Varies locallyNo countywide requirement to connect to utilities was found; whether a certificate of occupancy requires a grid hookup is set by your specific town, city, or village, not the county.
