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

Yes. Pennsylvania's Uniform Construction Code applies in Centre County, and owners must obtain a building permit before starting covered work^2,5. Most municipalities administer the UCC themselves or use a certified third-party agency; enforcement arrangements differ in municipalities that opted out². Inspections are required for regulated residential construction and changes to electrical, gas, mechanical or plumbing systems⁵. Qualifying agricultural buildings without habitable space are excluded from the state Construction Code Act, although zoning, fire, electrical, health and environmental requirements may still apply⁸. Pennsylvania generally does not license most construction contractors, and an owner working without compensation on the owner's own primary residence may act as the builder, but municipal licensing rules can still apply⁷.

The permit issuer varies by municipality. Centre County property owners may deal with their township or borough, a certified third-party code agency, or the Pennsylvania Department of Labor and Industry, depending on local UCC administration². Call the township or borough first and ask who accepts residential UCC applications, sets local fees and schedules inspections for that parcel; the published state fee schedule applies only when the Department is the issuing authority¹¹. Centre County Planning & Community Development assists the county's 35 municipalities and can be reached at (814) 355-6791³. State-handled applications require the political subdivision and county plus the applicable form, fee, plans, site plan and checklist; local procedures may differ⁵. A UCC certificate of occupancy must be issued before a covered building or facility can be used⁵.

Centre County has no countywide zoning ordinance: zoning is set by each township or borough, and the county's own housing document says 22 of 36 municipalities have adopted zoning ordinances¹. Not every municipality has adopted one, so ask the township or borough whether the parcel is zoned¹. Centre County Planning & Community Development assists the county's 35 municipalities with zoning and subdivision ordinances, GIS mapping and other planning work³. Pennsylvania law allows county zoning only as a backstop in a municipality with no zoning ordinance, and that county authority ends when the municipality's own ordinance takes effect¹². Setbacks, minimum dwelling size, lot coverage and building height are set locally; as one example, Haines Township requires 1 acre, 100 feet of width and no more than 35% impervious coverage for a single-family detached dwelling in its Forested Conservation and Agriculture districts¹³. The county subdivision ordinance does set mobile-home standards where a municipality lacks its own subdivision ordinance, including a minimum 5,000-square-foot lot and 50-foot width, but municipal rules still apply¹⁴.

On-lot sewage permitting and enforcement in Centre County are handled by local agencies, generally a municipality or joint local agency, under Pennsylvania's Act 537 framework⁴. A local permit is required for individual and community on-lot systems and retaining tanks, with a separate exception for large-volume systems⁴. A narrow exemption can apply on a contiguous tract of at least 10 acres serving the owner or immediate family, but ownership, local-ordinance and siting conditions must all be met¹⁵. A completed system cannot be covered until the permit issuer approves it, subject to the state's limited 72-hour provision after notice of completion¹⁶. Only about 16.1% of Centre County soil is rated as not severely limited for a conventional drain field, so obtain a site evaluation before treating a listing as septic-ready¹⁷.

We could not confirm a countywide rule allowing long-term RV living, temporary camping or tiny-home occupancy on private land in Centre County. Ask the township or borough whether the parcel's zoning district allows the proposed use, what setbacks apply, and whether occupancy during construction is permitted⁶. Pennsylvania's state-park campground limits do not answer whether an RV may be occupied on private land¹⁸. A manufactured home installed to the manufacturer's approved design is largely outside the UCC, but utility connections, grading, additions, alterations, resale or relocation can bring work under the UCC; local siting and land-use approval remain separate questions⁹. A tiny home used as a dwelling should therefore be cleared with both the municipal zoning contact and the responsible UCC code agency before purchase or placement.

1. Identify the township or borough and ask for the parcel's zoning district, dimensional standards and responsible UCC code agency^2,6.
2. If the proposal divides land or qualifies as land development, determine whether the municipal ordinance or Centre County's subdivision ordinance governs the review³.
3. If the site will use on-lot sewage, identify the responsible municipality or joint local agency and obtain its permit⁴.
4. Apply for the UCC building permit before covered work begins; a state-handled application requires the applicable forms, fee, plans, site plan and checklist⁵.
5. Arrange required inspections with the responsible code agency⁵.
6. Obtain a PennDOT Highway Occupancy Permit for access to a state highway; driveway culverts affecting a regulated stream or floodway can also require stream authorization^19,20.
7. Obtain the UCC certificate of occupancy before using the building⁵.

Confirm the municipality, zoning district, code agency and applicable subdivision ordinance before relying on a listing's description of buildability^6,21,22. Only about 16.1% of Centre County soil is rated as not severely limited for a conventional septic drain field, so seek a site evaluation before committing to an on-lot sewage plan¹⁷. Centre County is 81.2% wooded, while 56.6% of its land has a slope of 15% or less; clearing, access and grading can materially shape the usable building envelope¹⁷. A driveway connecting to state highway land or a PennDOT drainage facility needs a Highway Occupancy Permit, while a driveway culvert affecting a regulated stream or floodway may need separate stream authorization^10,20. Farmland value is about $8,311 per acre, the typical home value is about $356,480, the effective property-tax rate is about 1.1%, and the median annual property-tax bill is about $3,282¹⁷.
