Off-Grid Living in Westmoreland County, Pennsylvania

Researching off-grid rules in Westmoreland County, Pennsylvania comes with one big caveat right up front: the county itself has no countywide zoning ordinance, and no countywide building or septic department either. Westmoreland County's own planning office says plainly that zoning is "fully within the purview of local municipalities," and a number of the roughly 65 townships and boroughs haven't adopted zoning at all. So almost everything I can tell you here depends on which specific township or borough your land sits in, and you really do need to call that municipality before you buy or build.

Zoning: With no county ordinance, whether you can occupy raw land, live in an RV, or park a tiny home depends entirely on the local municipality. Some townships have zoning ordinances (often hosted on eCode360), some don't. The county's planning department can point you to the right municipal contact, but they don't set the rule themselves.

Building permits: Pennsylvania's Uniform Construction Code (UCC) governs construction statewide, but the county confirms that permit review is handled municipality by municipality, in-house, through a contracted inspection company, or by the state Department of Labor and Industry if a township opts out. There's no single county building department.

Septic: This is regulated under Pennsylvania's Sewage Facilities Act (Act 537), which requires a local agency, usually the municipality itself, to run the permitting program. Westmoreland has no county health department doing this, so each township has its own certified Sewage Enforcement Officer (SEO) issuing on-lot septic permits. The county's FAQ also points septic questions to the DEP Bureau of Water Quality Management. Composting toilets aren't separately addressed locally, so state DEP standards (NSF Standard 41) apply by default.

Greywater: No county-specific ordinance exists, so greywater is treated as sewage under the same Act 537 framework, administered by your township's SEO. Treat it as restricted until your township tells you otherwise.

Rainwater: No local rule was found; the state baseline applies, meaning rainwater harvesting is fine for non-potable uses but can't be your sole approved water supply.

Wells: Pennsylvania doesn't require a well permit statewide, and Westmoreland County doesn't add one either. The DEP's New Stanton District Office and Penn State Extension offer voluntary water testing help.

Utilities: No county-wide mandate to hook up to electric, water, or sewer was found. Any such requirement would come from your specific municipality's code or a local authority like the Municipal Authority of Westmoreland County (MAWC) in areas it serves.

Bottom line: treat Westmoreland County as a "call your township first" situation for nearly every off-grid question.
