Off-Grid Living in Cumberland County, Pennsylvania

If you're looking at raw land in Cumberland County, Pennsylvania and dreaming of going off-grid, here's the first thing I want you to understand: Cumberland County itself doesn't run zoning or building code enforcement. There's no countywide zoning ordinance. That authority sits with the individual townships and boroughs, 30 of the county's 33 municipalities have their own zoning ordinances, and three don't. The county Planning Department (per its own site) plays a coordinating and mapping role, and directs zoning questions right back to the municipality. So step one for any parcel is always: call that specific township or borough.

Zoning and dwellings. Whether you can put a tiny home, RV, or unconventional dwelling on a piece of land depends entirely on that municipality's ordinance. I haven't found a county-level standard for tiny homes or RV occupancy. Pennsylvania's Uniform Construction Code (UCC), based on the 2018 IRC, sets the statewide baseline for stick-built dwellings, but accessory dwellings and RV siting rules are set locally.

Building permits. Pennsylvania's Department of Labor & Industry notes that over 90% of the state's municipalities administer and enforce the UCC themselves, using their own staff or a third-party agency. Cumberland County has no county building department, so who issues your permit and how they enforce it is a township-by-township question.

Septic and composting toilets. This one's state law with local administration. Under PA's Sewage Facilities Act, certified Sewage Enforcement Officers (SEOs), employed by the municipality (or a group of municipalities), issue on-lot sewage permits and inspect systems. Composting toilets get evaluated case by case by your local SEO under DEP's alternate-system framework, not blanket-approved countywide.

Greywater and rainwater. I found no Cumberland County-specific ordinances for either. Greywater looks to be swept into the same state Sewage Facilities Act framework as septic, meaning your SEO likely has a say. Rainwater harvesting for non-potable use appears to follow the general state baseline, just don't plan on it as your sole potable source for a permanent residence.

Wells. Pennsylvania DEP is explicit: it does not regulate private wells. That leaves a patchwork where some Cumberland County townships impose their own permit and inspection requirements (a neighboring Adams County township ordinance is a good example of the type of local rule that exists), while others may have none. Confirm directly with your township.

Utility disconnection. No countywide rule bars you from living off-grid, but some municipalities have mandatory sewer-connection ordinances if you're within a set distance of a public line. That's a local ordinance question, not a county one.

Bottom line: Cumberland County hands almost everything that matters, zoning, building, septic, wells, to the municipal level. Don't assume what worked in the next township over applies to you.
