Lycoming County, Pennsylvania requires a building permit for most new construction under the statewide Uniform Construction Code (UCC), but the county itself does not issue that permit — it comes from your municipality or a UCC-certified third-party agency, after you clear zoning where it applies1. Lycoming County accepts zoning applications only for the areas it serves; other municipalities may administer their own zoning2. Septic systems follow Pennsylvania's Act 537 framework with local municipal administration3.

Do you need a building permit in Lycoming County, Pennsylvania?
Yes, for most new construction: Pennsylvania's statewide Uniform Construction Code requires a building permit, and builders throughout the state must follow it14. Lycoming County does not issue this permit itself; in municipalities that opted in to the UCC, either the municipality's own staff or a certified third-party agency the property owner or contractor hires enforces the code, while the state Department of Labor and Industry handles commercial code enforcement in municipalities that opted out14. A UCC permit must be obtained before work starts, and a certificate of occupancy is required before the building can be used11. Qualifying agricultural buildings — barns, hay or feed storage, livestock or poultry housing, and milk houses — are excluded from the Construction Code Act entirely, though local zoning and other rules can still apply8. Pennsylvania's triennial UCC update took effect in January 2026, so confirm which edition applies to your project4.
Who issues building permits in Lycoming County, and how do you reach the county's zoning office?
Lycoming County has no countywide building or UCC permitting office; call your township or borough office first to learn whether it enforces the Uniform Construction Code itself or through a certified third-party agency1. Before applying for a UCC permit in a county-served area, contact the Lycoming County Zoning Office at 570-320-2130 or [email protected], or visit 33 W. Third St, 3rd Floor (Third Street Plaza), Williamsport, PA 1770110. The office does not accept applications for every municipality, so use its jurisdictional map to identify the authority for the site210. Lycoming County publishes zoning and subdivision fee schedules, but the listed schedules are dated 2021 and are not confirmed current for 2026; ask the applicable reviewing office for today's charge before filing12.
Does Lycoming County have zoning?
Yes, but the correct zoning authority depends on the parcel: Lycoming County accepts applications only in the areas it serves, while other municipalities may administer their own zoning2. The county publishes its zoning ordinance, a zoning-and-subdivision jurisdictional map, and zoning maps for partner municipalities, but those county districts do not necessarily apply in every municipality13. Pennsylvania law lets a county zone only where a municipality has no zoning ordinance in effect, and a later municipal ordinance replaces county zoning within that municipality14. Use the jurisdictional map first, then get the applicable district rules for setbacks, minimum lot size, building height and dwelling size from the county office or the township or borough that serves the parcel13.
How do septic permits work in Lycoming County?
Pennsylvania DEP supplies the Act 537 framework for onlot sewage, while local municipalities exercise the relevant local powers; the available county-specific material does not establish one Lycoming County permitting or inspection process3. State law generally requires a permit from the local agency before an onlot system is installed or a building it serves is occupied or used, so call the township or borough to identify its Sewage Enforcement Officer before design begins5. A qualifying owner or immediate-family residence on a contiguous tract of at least 10 acres may receive an exemption, subject to ownership, notice, local-ordinance and siting conditions5. A completed system cannot be covered until the permit issuer approves it, subject to the state's 72-hour provision15. Only about 6.5% of Lycoming County soils rate free of severe limits for a conventional drain field, so make the site evaluation an early contingency7.
Can you live in an RV or tiny home on your land in Lycoming County?
Lycoming County's own facts do not confirm a countywide rule for living in an RV or tiny home on your own rural parcel; zoning depends on whether your township or borough partners with the county or runs its own zoning, so call the Lycoming County Zoning Office at 570-320-2130 to ask about your specific parcel109. Pennsylvania's state park campgrounds cap RV stays at 14 consecutive nights in summer and 21 the rest of the year, but those limits govern state park campsites, not what you may do on your own land16. A manufactured home installed to the manufacturer's approved design is generally exempt from the Uniform Construction Code, but relocating it, adding to it, or reselling it later brings it back under the UCC, on top of whatever local zoning and septic approval it needs17.
Building a home in Lycoming County: the steps, in order
- Use the county's jurisdictional map, then call the identified township, borough or county office to confirm who handles zoning, subdivision review and UCC administration for the parcel2181.
- If the county serves the site, apply through the Lycoming County Zoning Office at 570-320-2130 or [email protected] and confirm the current fee before filing1012.
- If the project divides land or is land development, follow the ordinance, submission requirements and review process of the authority shown on the jurisdictional map18.
- Ask the municipality to identify its Sewage Enforcement Officer, then complete the Act 537 septic process and site evaluation357.
- Obtain the UCC building permit before work starts and any PennDOT permit needed for access on state highway land1119.
- Complete required inspections and obtain the UCC certificate of occupancy before using the building11.
What to check before you buy land in Lycoming County
Start with jurisdiction: the county's maps determine whether Lycoming County or a municipality reviews zoning and subdivision plans, and county zoning districts do not necessarily apply everywhere21813. Lycoming County is heavily wooded and hilly: about 81.2% is forested, and about 46.5% of the land has a slope of 15% or less, so inspect grade, clearing needs and access2021. Only about 6.5% of county soils rate free of severe limits for a conventional drain field, so make septic feasibility a purchase contingency7. Development in a Special Flood Hazard Area requires a municipal floodplain permit or equivalent before work begins22. For a private well, Pennsylvania licenses commercial drilling companies but exempts owners drilling on their own or leased land; the available material does not confirm a separate Lycoming County well permit23.
Watch-outs
- Lycoming County does not accept zoning applications for every municipality; check the county's zoning coverage map before assuming the county's zoning office serves your parcel10.
- Pennsylvania's triennial Uniform Construction Code update took effect in January 2026, so confirm with your municipality or its UCC agency which edition applies to your project4.
- No Lycoming County source confirms an owner-builder exemption from using a licensed contractor or certified third-party UCC agency; ask your municipality directly before planning to build it yourself6.
- A driveway or road connecting to a state highway needs a separate PennDOT highway occupancy permit before you build it19.
