In Lancaster County — a fast-growing south-central county — building permits are issued at the municipal level by each city, borough, and township (or its certified third-party agency), not by the county. All enforce the statewide UCC.
This guide covers what requires a permit, each municipality's permitting process, fees, trade permits, and inspections — so your Lancaster County project stays on track.
Lancaster County blends the City of Lancaster, growing boroughs, and rural townships with significant agricultural and Plain-community construction. Building permits come from your specific municipality — there is no unincorporated land and the county does not issue building permits. Many rural townships rely on certified third-party agencies. Note that some agricultural buildings have limited UCC exemptions. Confirm your municipality and its enforcement model first.
Pennsylvania enforces a statewide Uniform Construction Code (UCC), established by the Pennsylvania Construction Code Act and administered by the Department of Labor & Industry (L&I) through its Bureau of Occupational & Industrial Safety, with updates reviewed by the UCC Review & Advisory Council (RAC). As of July 13, 2025, the UCC adopts the 2021 ICC code series (IBC, IRC, IMC, IPC, IFGC, IECC) with Pennsylvania amendments (2018 accessibility provisions remain in effect). Crucially, Pennsylvania is fully municipalized — there is no unincorporated land, and building permits are issued at the municipal level (city, borough, or township) or its certified third-party agency. Over 90% of Pennsylvania's 2,562 municipalities have opted in to local enforcement; in opt-out municipalities, L&I handles commercial enforcement and a property owner hires a certified third-party agency for residential. Municipalities may adopt local amendments only to make the code more restrictive, never less.
What requires a building permit in Lancaster County?
Under locally adopted codes, a permit is required for most construction activities:
Permit required
- New residential and commercial construction, additions, conversions
- Structural and load-bearing alterations
- Reroofing, windows, siding, and exterior modifications
- Electrical service changes and most wiring work
- HVAC installations, changeouts, and ductwork

Get the permit issued before starting work. Building without a permit anywhere in Lancaster County can result in fines, stop-work orders, and mandatory removal of unpermitted work — enforced by the municipality or its third-party agency.

Lancaster County trade permits
Electrical, plumbing, and mechanical work each needs its own permit and appropriately licensed tradespeople.
Electrical permits
Required for service installations, panel upgrades, solar PV, EV chargers, and most wiring alterations. Pennsylvania has no statewide electrician license — electrical licensing is handled by the municipality (e.g., Philadelphia and Pittsburgh license electrical contractors). Work is inspected against the National Electrical Code as adopted by the UCC, typically by the municipality or a certified third-party agency.
Plumbing & gas permits
Required for new plumbing, repipes, water-heater changeouts, fixtures, backflow, and sewer/gas connections. Plumber licensing in Pennsylvania is local — issued by the municipality or, in some areas, a county/city health department (e.g., Philadelphia and Allegheny County license plumbers). Work is inspected against the plumbing provisions of the UCC.
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, ductwork, and venting. Pennsylvania has no statewide HVAC license; mechanical licensing is handled locally where required (e.g., Philadelphia). Work is inspected against the mechanical and fuel-gas provisions of the UCC.
Miscellaneous & specialty
Fencing, pools, decks, sheds, and patio covers may require special permits depending on size and utility hookups. Demolition, sign, and right-of-way permits follow separate tracks.
Verify contractor registration & local licensing. Pennsylvania has no statewide general contractor or trade license. Instead, under the Home Improvement Consumer Protection Act, any contractor performing more than $5,000 of home-improvement work per year must hold a Home Improvement Contractor (HIC) registration with the Pennsylvania Office of Attorney General (renewed every two years; this is a registration, not a license — no exam). Trade licensing (electrical, plumbing, HVAC) and general-contractor licensing are handled locally: Philadelphia (Dept. of Licenses & Inspections) and Pittsburgh (Dept. of Permits, Licenses & Inspections) run their own contractor and trade licenses, and cities like Allentown, Erie, Reading, and Scranton also license locally. Verify HIC registration at the PA Attorney General HIC search.
How to get a building permit in Lancaster County
Identify the municipality & its UCC enforcement
Determine which city, borough, or township your property is in (Lancaster County has no unincorporated land). Confirm whether that municipality has opted in (local or third-party enforcement) or opted out (L&I commercial; third-party residential).
Confirm permit requirement & zoning
Contact that municipality's code office (or its third-party agency). Confirm zoning, the correct permit type, and whether your project requires a permit. Verify any floodplain requirements before applying.
Prepare your application package
Assemble the permit application, site plan, construction drawings (sealed by a Pennsylvania-licensed design professional where required), scope and valuation, HIC registration number, and proof of insurance.
Submit to the enforcing agency
Submit to the municipality, its certified third-party agency, or — in opt-out municipalities for commercial work — Pennsylvania L&I. Upload required documents and pay fees.
Plan review & corrections
The enforcing agency reviews against the UCC (2021 ICC series). Address any correction notices promptly.
Inspections & Certificate of Occupancy
Schedule UCC inspections (footing/foundation, framing, rough-in MEP, final) with the enforcing agency. A Certificate of Occupancy is required before legal occupancy.
