Off-Grid Living in Lancaster County, Pennsylvania

I'll be upfront about the first thing I found researching Lancaster County, PA: there's no countywide zoning ordinance, no countywide building department, and no county health department. Pennsylvania is fully municipalized, meaning every one of Lancaster County's roughly 60 townships, boroughs, and the City of Lancaster writes and enforces its own rules within a state framework. The Lancaster County Planning Department only does advisory review of subdivision and land development plans for consistency with the state Municipalities Planning Code, it doesn't issue permits or set zoning itself. So almost everything I can tell you here has to be confirmed at the township or borough level for your specific parcel.

Zoning: Each municipality adopts its own zoning ordinance. Many rural townships use agricultural zoning meant to preserve farmland, which can restrict non-farm residential uses, including some off-grid setups, on ag-zoned parcels. Check your township's ordinance directly, often on eCode360 or via the township office.

Dwellings, tiny homes, RVs: I found nothing at the county level addressing these as dwellings. This is a township-by-township call layered on the state Uniform Construction Code (UCC) baseline.

Building permits: No separate county building code exists. Some municipalities, like the City of Lancaster, administer the UCC themselves. Others, like West Hempfield Township, use third-party plan reviewers and inspectors. If a municipality opts out entirely, the PA Department of Labor & Industry or a certified third-party agency steps in. Either way, the state UCC is the underlying code everywhere.

Septic and composting toilets: No county health department runs sewage permitting here. Instead, each township appoints its own certified Sewage Enforcement Officer (SEO) who issues permits and does soil/perc testing under the state's Act 537 program and 25 Pa. Code Chapter 73, which sets standards like separation from the seasonal high water table. Composting toilets fall under the general state baseline (NSF Standard 41); I didn't find a Lancaster-specific composting toilet rule.

Greywater: No county or municipal-specific ordinance turned up. It's treated as sewage under the same statewide Act 537/Chapter 73 framework your local SEO enforces.

Rainwater harvesting: For non-potable use, I found no Lancaster County restriction beyond the general state baseline, so this looks permitted, but I'd confirm nothing local has changed that.

Wells: PA DEP doesn't regulate private wells directly; drillers must be licensed under the state's Act 610, which also requires giving owners a completion report. I found no Lancaster County-added well permit requirement, unlike some PA counties that do impose one. The Lancaster County Conservation District handles erosion, sediment, and stormwater, not well permitting.

Utility disconnection: Whether an occupancy permit requires hookups to water, sewer, or electric is a township-level call, not a county one. You'll need to ask your specific municipal office.

Bottom line: in Lancaster County, "off-grid legal" almost entirely depends on which township or borough your land sits in. Start there before assuming anything from a neighboring parcel applies to you.
