Off-Grid Living in Dauphin County, Pennsylvania

Dauphin County, Pennsylvania is a tricky place to research off-grid living because, structurally, there's no countywide zoning ordinance and no county health department running septic permits. I want to be upfront about that: this county delegates land use, building enforcement, and sewage permitting down to its 40 individual municipalities (townships, boroughs, and the City of Harrisburg). So almost everything below comes with the same caveat, confirm with the specific township or borough where your land sits.

Zoning. The Dauphin County Planning Commission (DCPC) coordinates land-use planning across the county under Pennsylvania's Municipalities Planning Code, but it doesn't itself zone land. Each municipality writes its own zoning ordinance. Some, like East Hanover Township, have adopted their own maps and rules relatively recently. There's no way I can tell you "off-grid is fine" or "not fine" countywide, you have to check the municipality.

Dwellings, tiny homes, RVs. I found no Dauphin County-level rule specifically addressing tiny homes or RVs as permanent residences. This is set locally, so the state's Uniform Construction Code (UCC) is the default baseline unless a township layers on its own restrictions.

Building permits. Pennsylvania's UCC is the statewide building code baseline, and the state Department of Labor and Industry says the large majority of PA municipalities administer and enforce it themselves, either with their own staff or a contracted third-party agency. Where a municipality has opted out, L&I handles commercial enforcement while a certified third party (hired by you) handles residential. Dauphin County has no central building department; Susquehanna Township and the City of Harrisburg, for instance, each run their own permitting offices.

Septic and composting toilets. Pennsylvania's Sewage Facilities Act (Act 537) requires a local agency, usually the municipality, to run septic permitting through a certified Sewage Enforcement Officer (SEO). In Dauphin County that's handled township-by-township; Lower Paxton Township and Susquehanna Township are two examples with their own SEOs. Composting toilets aren't separately addressed here; the operative rule is the state's NSF Standard 41 baseline.

Greywater. I found no Dauphin County or municipal ordinance that loosens Pennsylvania's default position, which treats greywater as sewage subject to the same permitting framework. Assume the strict state baseline unless your township tells you otherwise.

Rainwater harvesting. No county-specific rule turned up. State DEP guidance, which allows rainwater collection for non-potable uses but not as a sole potable source, applies by default.

Wells. No separate county well-permitting authority exists. The Dauphin County Conservation District runs water-resource stewardship programs but doesn't issue well permits. The county falls under PA DEP's Southcentral Regional Office for state water-management matters, and the state's driller-licensing law (Act 610) is the baseline.

Utility disconnection. Not confirmed at the county level. If any occupancy-permit requirement for utility hookups exists, it would come from your specific township or borough code.

Bottom line: Dauphin County itself sets almost nothing directly. Your off-grid plans live or die by the specific township or borough's zoning, building, and SEO offices, so start there.
