Do you need a building permit in Lancaster County, Pennsylvania?

Yes. Before covered construction or building work begins in Lancaster County, the owner or an authorized representative must obtain a permit under Pennsylvania's statewide Uniform Construction Code158. The parcel's municipality administers the permit process rather than Lancaster County4. West Hempfield Township is one example: it administers the UCC with third-party plan reviewers and inspectors and may require both zoning and building-code permits16. Required residential inspections include the foundation, building systems, framing and masonry, wallboard, and a final inspection9. A covered building cannot be occupied until the building code official issues a certificate of occupancy after compliant final inspection14. A qualifying agricultural building without habitable space is excluded from the Construction Code Act, although municipal zoning and other rules can still apply11. Emergency repairs or equipment replacements may start without a permit if the application reaches the building code official within three business days1.

Who issues building permits and zoning approval in Lancaster County, and how do you reach them?

Lancaster County does not run the building-permit counter; the township, borough, or City of Lancaster serving the parcel handles the UCC process415. Over 90% of Pennsylvania municipalities administer and enforce the code locally, either with their own staff or a certified third-party agency, and procedures differ from one municipality to the next10. The application (form UCC-3) must name the township or borough and the county so jurisdiction can be determined17. Identify the municipality before requesting its application, fee schedule, plan requirements, inspection sequence, and zoning approval. West Hempfield Township is only an example: its office is at 3476 Marietta Avenue in Lancaster, reachable at (717) 285-5554, Monday through Friday from 8 a.m. to 4:30 p.m.16. The Lancaster County Planning Commission is at 150 North Queen Street, Suite 320, Lancaster, and can be reached at 717-299-833318. The commission reviews subdivision and land-development plans for consistency with the county comprehensive plan and gives advisory comments, but municipal approval is required before e-recording19.

Does Lancaster County have zoning?

Zoning in Lancaster County is a municipal question: the county's 60 municipalities contain approximately 550 separate zoning districts with different regulations and permitted uses20. The county's simplified zoning material is a planning tool, not the source of a parcel's municipal zoning rules20. Ask the parcel's township, borough, or city about RV occupancy, tiny homes, accessory dwellings, setbacks, lot coverage, building height, and minimum lot or dwelling size because we could not confirm one countywide standard for those topics. The Borough of Adamstown has its own zoning chapter21. Subdivision and land-development plans require approval by the relevant municipality, while the Lancaster County Planning Department provides advisory review; applications must be received at least 30 days before the desired Planning Commission meeting22. Some qualifying plans get expedited review for a $100 base fee, with standard county review fees reduced by 50%23.

How do septic (onlot) permits work in Lancaster County?

Lancaster County has no single county septic counter; local agencies carry out on-lot sewage permitting and enforcement through Sewage Enforcement Officers624. The local agency issues permits for retaining tanks and individual or community on-lot systems, while large-volume systems are an exception25. An individual system serving only the owner or immediate family on at least 10 contiguous acres may qualify for a permit exemption, but only when the statutory conditions are met, and a municipality may still require a permit by ordinance26. The system generally must remain uncovered until the permit issuer approves covering it27. About 45.1% of county soils lack severe limitations for a conventional drain field, so parcel-level testing still matters28.

Can you live in an RV or tiny home on your land in Lancaster County?

We could not confirm a countywide rule allowing residential RV use, temporary camping, or tiny-home occupancy on private land in Lancaster County. The answer turns on the parcel's municipal zoning district, and Lancaster County's municipal districts have different permitted uses and regulations29. Ask the township, borough, or City of Lancaster whether the proposed unit is a permitted dwelling, where it may sit, whether temporary occupancy during construction is allowed, and what utility or sewage approvals apply. A new residence using a composting or similar water-conservation toilet still needs an approved method for washwater or excess liquid, generally under the same permit30. A tiny home subject to the UCC requires a building permit, applicable inspections, and a certificate of occupancy before use8931. A qualifying recreational cabin can be excluded from the Uniform Construction Code if the owner equips the kitchen and sleeping areas with a smoke detector, fire extinguisher and carbon monoxide detector, and files affidavit form UCC-13 or written proof of insurance with the municipality32.

How do you build a home in Lancaster County, step by step?

  1. Identify the parcel's township, borough, or city and confirm its zoning district, permitted use, setbacks, and lot standards29.
  2. If the project divides land or constitutes land development, obtain municipal approval and submit it for county advisory review19.
  3. For an on-lot system, contact the local Sewage Enforcement Officer and secure the required approval before installation2425.
  4. Obtain municipal zoning approval and the UCC building permit before starting covered work8.
  5. For UCC-covered construction in a floodplain, provide the required documentation sealed by a registered design professional and ask the municipality about any separate floodplain approval, since the state rule we reviewed does not lay out the local floodplain permit process33.
  6. For access to a Commonwealth highway, secure the PennDOT highway occupancy permit before driveway access is allowed34.
  7. Schedule the required construction inspections9.
  8. Obtain the certificate of occupancy before using the building31.
  9. Before a public electric or gas utility connects completed UCC-regulated construction, provide written proof that the required inspections passed35.

What should you check before buying land in Lancaster County?

Start with municipal zoning because permitted uses and dimensional rules vary among approximately 550 districts countywide20. Check whether public sewer is available or whether the lot can support an approved on-lot system; about 45.1% of county soils lack severe limitations for a conventional drain field28. We could not confirm a countywide water or sewer connection mandate, so ask the municipality and serving utility what connections the parcel requires. For a private well, Pennsylvania licenses and permits drilling companies but excludes homeowners and farmers drilling their own wells on owned or leased land from that licensing rule; the state does not set private-well construction standards36. Confirm floodplain status because UCC-covered floodplain construction requires sealed design documentation37. Verify whether access is to a state or municipal road because a Commonwealth-highway driveway requires a PennDOT permit34.

Watch-outs

  • Lancaster County has approximately 550 zoning districts across 60 municipalities, so a use allowed in one township or borough may not be allowed in another5.
  • Pennsylvania generally lets an owner perform uncompensated work on the owner's own primary residence without a statewide contractor license, but that does not remove Lancaster County's municipal UCC permit and inspection requirements789.
  • West Hempfield Township's contact information in this guide is one example municipality only, not Lancaster County's building department; do not call West Hempfield about a parcel located in a different township, borough, or the City of Lancaster16.
  • The Pennsylvania Uniform Construction Code was updated effective January 1, 2026, so ask the municipality which code edition it is applying to a permit filed now10.
