Building permits, zoning and septic rules in Indiana County, Pennsylvania

Yes: Pennsylvania's statewide Uniform Construction Code requires a building permit for new residential construction, and in Indiana County that permit is issued by the county's own Office of Planning & Development for most boroughs and townships¹. The county's UCC office administers permits for most of the county's boroughs and townships; Center Township now administers its own UCC building permits, effective April 13, 2026, and any municipality not on the county's list issues its own permits directly, so confirm which applies to your parcel before you apply¹. Homeowners and businesses doing their own construction work, and contractors without workers' compensation insurance, must file a notarized state-required form with the building permit application¹. Whether Indiana County recognizes a separate owner-builder exemption from the UCC permit itself is not established on the county's published pages, so ask the Office of Planning & Development directly¹.

Inspections are required during construction, and a residential building may not be occupied without a certificate of occupancy issued by a building code official after a compliant final inspection⁷. The building permit does not cover septic: on-lot sewage permits are issued separately by the local sewage agency⁸.

The Indiana County Office of Planning & Development, at 801 Water St. in Indiana, administers Uniform Construction Code building permits for most of the county's boroughs and townships¹. Reach the office at 724-465-3870, Monday through Friday, 8:30 a.m. to 4:30 p.m¹.. For municipalities served by the county, submit the application by mail or in person with the fee and drawings; applicants who are unsure which form applies should contact the office¹. Municipalities outside the county's service list use their own application process¹. Indiana County adopted a new Subdivision and Land Development Ordinance in August 2023; for a commercial or agricultural building project, ask the office's Planning Section whether a review under that ordinance is required before you submit your building permit application¹.

Zoning in Pennsylvania is primarily a municipal matter, and that is true in Indiana County too: your own borough or township, not the county, sets most zoning rules for your parcel⁹. Indiana County itself administers only a narrow Special Recreation and Conservation Zoning Ordinance, which creates buffer and conservation zoning districts around three county parks, Blue Spruce Park, Pine Ridge Park, and Hemlock Lake, plus Yellow Creek State Park, to protect them from encroaching land uses^3,10. Inside those buffer and conservation zones, new uses or changes to existing uses must be reviewed and approved by the Indiana County Zoning Officer or the Indiana County Zoning Hearing Board¹⁰. Outside those specific park-buffer zones, Pennsylvania law lets a county zone only where a municipality has no zoning ordinance of its own, and a municipality's own later ordinance takes over from the county's the moment it is adopted¹¹. Before you buy, confirm with your specific township or borough whether it has its own zoning ordinance, since Indiana County's own zoning reach is limited to those park buffers¹⁰.

On-lot sewage permitting in Indiana County is administered by local agencies, with Pennsylvania's Department of Environmental Protection providing oversight; the Indiana County Sewage Enforcement Agency is listed as a delegated joint local agency⁴. Because the responsible agency can vary, ask the borough, township, or joint agency which Sewage Enforcement Officer covers the parcel before ordering tests or filing an application⁴. A local-agency permit is generally required before installing or constructing an individual or community on-lot system, or occupying or using a building served by one⁶. An individual system serving an owner or immediate-family residence on a contiguous tract of at least 10 acres may qualify for an exemption, subject to ownership, siting, notification, and local-ordinance conditions⁶. Once built, the system cannot be covered until the original permit issuer or an authorized representative approves it; approval to cover is allowed after 72 hours without a refusal, excluding Sundays and holidays¹². Only about 0.6% of Indiana County's soils are rated free of severe limits for a conventional drain field, so arrange the site evaluation early and allow for a costlier system¹³.

Pennsylvania's clearest RV rules are written for state park campgrounds, not private rural land: a camper there can stay up to 14 consecutive nights from Memorial Day to Labor Day or 21 consecutive nights the rest of the year, must clear out for 48 hours between reservations, and is capped at 2 sleeping units per site with only one of them wheeled¹⁴. None of that establishes a right to live in an RV full-time on your own land in Indiana County; that question runs through whichever borough or township zoning ordinance covers your parcel, since Indiana County's own zoning reach does not extend past its park-buffer districts¹⁰. A manufactured home is treated differently: once it is installed to the manufacturer's approved design, Pennsylvania's Uniform Construction Code generally does not apply, but utility connections, grading not covered by that design, later additions, alterations, resale, or relocation all bring the UCC back into play, and the county's own permit process asks for a completed habitability guidelines checklist with a used-manufactured-home application^1,15. Confirm any tiny-home or manufactured-home siting plan with your specific municipality's zoning office before you buy.

1. Confirm which municipality zones your parcel and what its ordinance allows, since Indiana County's own zoning reach is limited to its park-buffer districts^9,10.
2. Ask the borough, township, or Indiana County Sewage Enforcement Agency which local agency and Sewage Enforcement Officer cover the parcel, then complete the septic review before finalizing the house plans^4,6.
3. Confirm whether the municipality is on Indiana County's list for Uniform Construction Code building permits or uses its own application process¹.
4. If a commercial or agricultural building is involved, ask the Office of Planning & Development's Planning Section whether Indiana County's 2023 Subdivision and Land Development Ordinance requires a review¹.
5. For a county-handled permit, submit the application by mail or in person with the fee and drawings, plus the notarized workers'-compensation form when required for self-performed work¹.
6. Do not cover the completed septic system until the original permit issuer or an authorized representative approves it¹².

Confirm which municipality actually zones the parcel and what its ordinance permits, since Indiana County itself zones only the buffer areas around Blue Spruce Park, Pine Ridge Park, Hemlock Lake, and Yellow Creek State Park^3,10. Identify the local agency responsible for septic before making an offer: only about 0.6% of Indiana County's soils are rated free of severe limits for a conventional drain field, so plan on an engineered or alternative system on much of the county's rural land^4,13. If the parcel is at least 10 acres, ask whether an individual system serving an owner or immediate-family residence could qualify for Pennsylvania's conditional permit exemption⁶. Development in a Special Flood Hazard Area needs a municipal floodplain development permit before work begins¹⁶. Construction in a flood plain that is subject to the Uniform Construction Code also requires the applicable flood-design documentation to be prepared and sealed by a registered design professional¹⁷. If the driveway will connect to a state highway, allow time for a PennDOT Highway Occupancy Permit, usually issued within about 30 days for a complete, compliant application¹⁸. Indiana County's median property tax bill is about $2,271 a year at an effective rate near 1.6%¹³.
