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 rulesStanislaus County, CA
Zoning & raw-land occupancy
RestrictedStanislaus County Planning Department administers its own countywide Zoning Ordinance (Title 21); minimum lot sizes depend on sewer/water access, and occupying raw land without an approved dwelling isn't a recognized use. source
Dwellings, tiny homes & RVs
RestrictedStanislaus County Code Enforcement explicitly prohibits living in an RV or travel trailer outside designated campgrounds; temporary mobile homes are allowed only in narrow cases like elder care or ag employee housing on qualifying zoned parcels.
Building permits & codes
RestrictedThe county requires permits reviewed through a centralized 'One Stop Shop' involving Planning, DER, Public Works, and the Fire Warden's Office; owner-builders need Assessor records and often septic documentation. source
Septic & composting toilets
RestrictedDER regulates septic/OWTS under its own Local Agency Management Program with specific setback and floodplain siting rules that go beyond generic state minimums. source
Greywater reuse
Generally allowedNo Stanislaus-specific greywater ordinance was found beyond the state Plumbing Code; treated as following the state baseline, but not confirmed as the full picture, so check with DER.
Rainwater harvesting
Generally allowedNo county-specific rainwater ordinance was found; appears to defer to the state Water Code/Rainwater Capture Act, but this isn't fully confirmed with the county.
Private wells & water rights
RestrictedDER is the Local Enforcement Agency for wells and has adopted its own Groundwater Well Siting and Construction Guidelines, including drawdown thresholds and registration/metering rules for larger or newer wells.
Living disconnected from utilities
Unclear - verifyNo standalone ordinance mandates utility hookups, but RV occupancy bans and septic/well permitting requirements make fully off-grid dwelling without approved water and wastewater systems difficult in practice; not confirmed as an explicit standalone rule.
