Indiana County, PA
40.4815, -79.4231Read this before you act on anything below. This is my researched starting point for Indiana 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 rulesIndiana County, PA
Zoning & raw-land occupancy
Varies locallyIndiana County has no countywide zoning ordinance; zoning is set (or not set) by individual boroughs/townships. The county instead runs a Subdivision & Land Development Ordinance (SALDO) covering most, not all, municipalities. source
Dwellings, tiny homes & RVs
Unclear - verifyNo county-specific rule for tiny homes or RVs as dwellings was found; this depends on whichever municipality has zoning and Uniform Construction Code enforcement. Check with your specific borough or township. source
Building permits & codes
RestrictedBuilding permits tied to land development go through Indiana County's Office of Planning & Development (ICOPD) when SALDO applies, but actual UCC permit issuance is typically handled by the municipality itself. source
Septic & composting toilets
RestrictedPennsylvania's Sewage Facilities Act (Act 537) requires a certified Sewage Enforcement Officer to approve on-lot septic before occupancy; most Indiana County townships use the contracted Sewage Enforcement Agency of Armstrong and Indiana Counties. source
Greywater reuse
RestrictedNo Indiana County-specific greywater rule was found; state sewage regulations enforced through the same Act 537 SEO structure treat greywater as sewage requiring an approved system. source
Rainwater harvesting
Unclear - verifyNo Indiana County or municipal ordinance on rainwater harvesting was found; the state default (legal for non-potable use) would apply, but this is not confirmed locally.
Private wells & water rights
Generally allowedPennsylvania DEP does not require well permits statewide, and Indiana County is served by DEP's Northwest Regional Office along with a voluntary Penn State Extension well-testing program; no county well-permitting ordinance was found. source
Living disconnected from utilities
Varies locallyNo countywide ordinance requiring grid utility connection was found; this is governed, if at all, by the municipality issuing your occupancy permit, so confirm with your specific borough or township.
