Off-Grid Living in Bucks County, Pennsylvania

I'll be upfront: Bucks County is a tricky place to research off-grid living because there's no single county rulebook for most of what matters. Bucks County has no countywide zoning or building code authority at all. Pennsylvania's Municipalities Planning Code hands that power to each of the county's 54 municipalities (48 townships and 6 boroughs), so your actual rights to build, park an RV, or live rustically depend entirely on which township or borough your land sits in. The Bucks County Planning Commission offers regional guidance, but it doesn't issue permits or write zoning rules.

Where the county does step in directly is sewage and wells, and it does so more aggressively than the state baseline. The Bucks County Department of Health (BCDH) is one of only four Pennsylvania counties where the county health department, not the state, runs on-lot sewage permitting. Any septic system, holding tank, spray irrigation setup, or alternate/experimental system needs a BCDH permit before you install it or occupy a structure served by it, under authority tied to the state's Clean Streams Law and Sewage Facilities Act. Some townships (Plumstead is one example in the notes) layer on their own pump-out schedules for existing systems, enforced locally.

Wells are the same story: Pennsylvania generally doesn't require a state permit for private wells, but Bucks County broke from that in 2007 and now requires its own well permit and inspection through BCDH, with a Residential Well Worksheet reviewed before you can legally use the water. Several townships (Upper Makefield is named in the notes) add a second, separate township well permit on top of the county one, so check both levels.

Greywater and rainwater harvesting have no dedicated Bucks County or BCDH rules that I could find. Greywater looks like it falls under the same broad sewage-facilities framework BCDH already administers, so treat it as restricted, not free-and-clear. Rainwater catchment appears to just inherit the Pennsylvania state baseline, fine for non-potable use, not a substitute for an approved water supply if you want a certificate of occupancy.

Dwellings, tiny homes, RVs as permanent residences, and full utility disconnection aren't addressed at the county level at all. That means it's 100% a township/borough call, tied to their zoning ordinance and their Uniform Construction Code enforcement, plus whatever their certificate-of-occupancy process demands. Newtown Township, for instance, requires a certificate of occupancy for new dwellings.

My honest bottom line: don't assume anything based on "Bucks County" rules alone. Call your specific township zoning office first, then loop in BCDH for septic and well permits. This isn't legal advice, just my read of the public research, and local officials are the final word.
