Read this before you act on anything below. This is my researched starting point for Adams County, PA, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesAdams County, PA

Zoning & raw-land occupancy

Varies locallyAdams County has no countywide zoning ordinance except in Germany Township, Menallen Township, and East Berlin Borough (by contract). Everywhere else, the township or borough writes and enforces its own zoning. source

Dwellings, tiny homes & RVs

Unclear - verifyNo countywide rule on tiny homes or RV occupancy was found; most municipalities participate in the NFIP so floodplain permits can apply. Confirm with your specific township or borough. source

Building permits & codes

RestrictedThe county Tax Services/Assessment office issues a Property Improvement Permit for tax purposes, but the enforceable Uniform Construction Code permit comes from your municipality or its code agency. Check both. source

Septic & composting toilets

RestrictedThe Adams County Health Department's Environmental Health Division licenses and inspects household sewage systems countywide, though some townships (like Hamilton) run their own Sewage Enforcement Officer programs under the same state law. Confirm which office has jurisdiction over your parcel. source

Greywater reuse

RestrictedNo county or municipal greywater-specific rule was found; greywater appears to be treated as sewage requiring permitted disposal under the state's Chapter 73 rules as enforced by the county Health Department. source

Rainwater harvesting

Unclear - verifyNo Adams County or municipal rainwater harvesting ordinance was found; this likely defaults to the state baseline allowing non-potable use only. Not confirmed as a distinct local rule.

Private wells & water rights

Generally allowedNo county-level well-drilling permit requirement was found. The county Health Department licenses private water systems and the Conservation District helps arrange water testing through a partner lab. source

Living disconnected from utilities

Varies locallyNo countywide requirement to connect to electric, water, or sewer utilities was found. Any such rule would come from your specific township or borough's occupancy requirements. source
