Off-Grid Living in Indiana County, Pennsylvania

Indiana County, Pennsylvania is one of those places where the county government itself has surprisingly little say over whether you can live off-grid. I want to be upfront about that because it changes how you should research your specific spot: there's no countywide zoning ordinance here. Zoning in Pennsylvania is a municipal power, so whether your land allows a tiny home, an RV as a dwelling, or minimum lot sizes depends entirely on which borough or township you're in. Some townships (Brush Valley, Cherryhill, Burrell) have adopted special zoning overlays, like a Special Recreation and Conservation district with a minimum lot size, but that's not countywide. Many other municipalities may have no zoning at all. You have to check with the specific borough or township office.

What the county does run is the Indiana County Subdivision & Land Development Ordinance (SALDO), administered by the Indiana County Office of Planning & Development (ICOPD). This applies to most municipalities in the county except six that run their own subdivision controls (White Township, East Wheatfield Township, Indiana Borough, Blairsville Borough, Burrell Township, and Homer City Borough). If your plan involves subdividing land or land development, expect to deal with ICOPD, and know that land development approval is generally required before a building permit gets issued. Pennsylvania's Uniform Construction Code (UCC) sets the building code baseline statewide, but actual permit issuance and inspection is usually a municipal function, not a county one.

Septic is where things tighten up regardless of township. Pennsylvania's Sewage Facilities Act (Act 537) requires a certified Sewage Enforcement Officer to approve any on-lot sewage system, and a home can't legally be occupied before that system is inspected and approved. Most Indiana County townships contract this out to the Sewage Enforcement Agency of Armstrong and Indiana Counties. A composting toilet doesn't get you out of this requirement for the rest of the house. Greywater falls under the same state sewage rules; I found no county-specific loosening of that.

Rainwater harvesting has no county or municipal rule I could confirm, so the state's general non-potable-use baseline applies. Private wells are permitted, and Pennsylvania DEP doesn't require well permits statewide; Indiana County is served by DEP's Northwest Regional Office for water testing resources, and Penn State Extension has run a voluntary, no-cost well/spring/cistern testing program locally. Finally, living disconnected from grid utilities: I found no countywide mandate to connect to electric or public water/sewer, but again, this is something your specific municipality's code office would confirm, since occupancy permits are issued locally.

Bottom line: treat "Indiana County rules" mostly as "Indiana County has no rule, ask your township." The exceptions are subdivision/land development (ICOPD) and septic (Act 537 SEO), which do apply more broadly.
