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

Yes. A property owner or authorized representative must obtain a UCC building permit before beginning covered construction or building work in Erie County¹. Pennsylvania's statewide Uniform Construction Code applies to builders, and its latest triennial update took effect January 1, 2026⁶. The permit authority depends on the municipality: local government or an authorized third-party agency may administer residential requirements¹. Permitted residential work must remain accessible for inspections of foundations, building systems, framing, masonry and wallboard, followed by a final inspection⁹. A residential building cannot be used or occupied until the building code official issues a certificate of occupancy¹⁰. Emergency repair work may begin before a permit only when the application reaches the building code official within three business days¹.

Start with the township, borough or city containing the parcel because Erie County building permits and zoning approvals are not handled through one countywide counter^2,3. Ask the municipality to identify its zoning officer and the municipal or third-party UCC agency serving the address¹. A complete state-administered UCC application generally includes the application, fee, construction drawings or specifications, site plan and any required special-inspection statement or related approval, but a municipal or third-party agency may add local steps¹. State Department fees apply only when that department issues the permit; municipal and third-party fees can differ¹¹. For subdivision questions, contact the Erie County Department of Planning and Community Development at 814-451-6336³. The county office reviews subdivision and land-development plans where the Erie County SALDO applies³.

Zoning in Erie County varies by municipality: 35 of the county's 38 municipalities have enacted municipal zoning³. That means the parcel's township, borough or city is the place to confirm allowed uses, dimensional rules and zoning approval before designing a house¹². Erie County subdivision review is a separate layer: 26 municipalities administer their own subdivision and land-development regulations, while the Erie County SALDO applies in the remaining 12³. Do not treat the county SALDO's special standards as universal residential zoning. Its minimum-lot-size and setback provisions cited here concern multifamily developments of 10 or more dwelling units, and its 35% lot-coverage limit applies to that same development category¹³. We could not confirm one countywide minimum dwelling size, ordinary residential setback or lot-coverage rule (Lawrence Park Township, for example, defines a single-family dwelling as at least 900 square feet on a permanent foundation)¹⁴; ask the municipality for the zoning district map and dimensional table for the parcel³.

Local agencies issue permits for covered retaining tanks and individual or community on-lot sewage systems in Erie County, except for limited categories such as large-volume systems⁴. The responsible local agency can be a municipality, a joint municipal body, a county or a county health department, so the issuer can differ by service area⁴. Septic permits stay a separate approval from the municipal building permit and zoning approval. The Erie County Department of Health states that it regulates on-lot septic and sewer systems and issues permits, but the published sources do not say which municipalities it serves and which have their own agency⁵. Call the department at 814-451-6700 to identify the agency serving the parcel before ordering tests or choosing a house site¹⁵. Pennsylvania requires a sewage permit before installing an on-lot system or occupying a building served by one, subject to a narrow exemption for a qualifying residence on a contiguous tract of at least 10 acres that meets the law's ownership, notice and siting conditions¹⁶. Virtually none of Erie County's mapped soil area rates better than very limited for a conventional drain field, so make septic feasibility an early purchase contingency⁸.

We could not confirm a countywide rule allowing long-term RV living, private-land camping or tiny-home occupancy in Erie County. Because zoning varies among Erie County municipalities, ask the township, borough or city whether the parcel's district permits the proposed dwelling and whether temporary occupancy during construction is allowed³. A tiny house used as a residence does not avoid the statewide permit rule merely because it is small; covered construction requires a UCC building permit before work begins¹. An owner who works without compensation on the owner's primary residence may fall outside Pennsylvania's general contractor-registration requirement, but that does not waive building permits, inspections or zoning approval^1,7,9. Erie County does require a Department of Health permit for any organized camp or campground, which covers commercial campgrounds, not a single RV on your own parcel¹⁷. State-park camping limits do not answer what is allowed on private land, so get the municipality's answer in writing before buying a parcel for RV or tiny-home use¹⁸.

1. Identify the parcel's township, borough or city and obtain its zoning district and dimensional standards³.
2. Ask that municipality which municipal or third-party UCC agency serves the address and what its application package and fee are^1,11.
3. If land will be divided or developed, determine whether the municipal ordinance or Erie County SALDO controls; county review may start with an optional sketch consultation³.
4. Confirm the on-lot sewage permitting agency and septic feasibility before fixing the house location^4,8.
5. Obtain the UCC building permit before regulated work starts¹.
6. If the driveway enters state-highway land or connects to PennDOT drainage, obtain a Highway Occupancy Permit¹⁹.
7. Keep work open for required inspections, pass the final inspection and obtain the certificate of occupancy before moving in^9,10.

Confirm zoning, subdivision jurisdiction and the permit agency with the parcel's municipality before relying on a listing description³. Make an approved sewage path a purchase condition because virtually none of Erie County's mapped soils rate better than very limited for a conventional drain field⁸. Check flood maps early: development in a Special Flood Hazard Area requires a municipal floodplain development permit or equivalent before work begins²⁰. Within Erie County SALDO jurisdiction, flood-prone projects face added design and mapping rules, and a site beside a watercourse without a delineated floodplain must keep structures at least 50 feet from the stream bank²¹. Determine who owns the road; work on state-highway land, including a new or changed driveway, requires a PennDOT permit, while ordinary local-road access requirements were not confirmed countywide¹⁹. Finally, budget using parcel-specific taxes rather than the county median; the median property-tax bill is about $2,754 a year⁸.
