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

Yes. A property owner or authorized representative must obtain a UCC building permit before beginning construction or building work in Lycoming County when the project is subject to Pennsylvania's Uniform Construction Code⁸. The municipality's enforcement arrangement determines whether the municipality, a certified third-party agency or the Pennsylvania Department of Labor and Industry administers the building permit². Required UCC inspections can include residential construction and electrical, gas, mechanical and plumbing work¹. A UCC certificate of occupancy must be issued before a covered building or facility is used¹. Qualifying agricultural buildings are excluded from the Construction Code Act, but zoning approval and septic permits can still apply^3,4,6. Pennsylvania's statewide UCC update took effect in January 2026².

The building-permit issuer in Lycoming County may be the municipality, a certified third-party agency or the Pennsylvania Department of Labor and Industry, depending on the municipality's UCC enforcement arrangement². Building-permit authority does not decide the other approvals: the Lycoming County Zoning Office handles zoning approval only in mapped county service areas, and the local sewage agency serving the parcel issues the septic permit^3,4. For county zoning, contact the office at 570-320-2130 or lycoplan@lyco.org, or visit 33 W. Third St, 3rd Floor (Third Street Plaza), Williamsport, PA 17701⁷. A county zoning application must be complete, signed and dated, include a plot plan, and arrive with payment⁹. The county publishes zoning and subdivision fee schedules dated 2021, but the sources do not establish that those schedules remain current; ask the reviewing authority for today's fee⁹.

Yes, but the correct zoning authority depends on the parcel: county zoning applies in municipalities served by Lycoming County's program, while other municipalities may administer their own zoning³. The county publishes its zoning ordinance, a jurisdictional map and zoning maps for partner municipalities, but the county's zoning districts do not necessarily apply in every municipality³. 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 municipality¹⁰. Use the jurisdictional map first, then request the applicable setbacks, minimum lot size, building height and dwelling-size rules from the county office or the township or borough serving the parcel³. We could not confirm one countywide set of dimensional standards. Septic permits remain a separate approval from the local sewage agency serving the parcel⁴.

Pennsylvania DEP supplies the Sewage Enforcement Officer certification and program framework, while local municipal administration also applies in Lycoming County¹¹. The applicable local agency issues permits for retaining tanks and individual or community on-lot systems; large-volume systems are an exception to ordinary local permitting responsibility⁴. Call the township or borough before design begins to identify the correct local agency and Sewage Enforcement Officer⁴. 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 conditions¹². Only about 6.5% of Lycoming County soils rate free of severe limits for a conventional drain field, so make septic feasibility an early purchase and design contingency⁵. We could not confirm one countywide inspection procedure; ask the local agency what inspections it requires.

We could not confirm a countywide rule for living in an RV or tiny home on a private rural parcel in Lycoming County. Zoning depends on whether the township or borough partners with the county or administers its own rules, so call the Lycoming County Zoning Office at 570-320-2130 about a parcel in its service area or contact the applicable municipality^3,7. Ask that zoning authority about occupancy, setbacks, minimum dwelling size and whether temporary RV use during construction is allowed. A manufactured home installed to the manufacturer's approved design is generally exempt from the Uniform Construction Code, but relocation, additions and certain later work bring UCC requirements back into play; zoning approval and septic permits remain separate^4,13.

1. Use the county's jurisdictional map, then call the identified township, borough or county office to confirm who handles zoning approval, subdivision review and UCC building permits for the parcel^2,3,9.
2. If the county serves the site, submit a complete, signed and dated zoning application with a plot plan and payment to the Lycoming County Zoning Office^7,9.
3. If the project divides land or qualifies as land development, follow the subdivision ordinance and review process of the authority shown on the jurisdictional map⁹.
4. Ask the municipality to identify its local sewage agency and Sewage Enforcement Officer, then obtain the required on-lot septic permit⁴.
5. Obtain the UCC building permit before work starts and any PennDOT driveway permit needed for access on state highway land^1,14.
6. Complete the required UCC building inspections and obtain a certificate of occupancy before using a covered building¹. Public electric or gas service for completed construction also requires written proof that the structure passed UCC inspections⁸.

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 everywhere^3,9. 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 access⁵. Only about 6.5% of county soils rate free of severe limits for a conventional drain field, so make septic feasibility a purchase contingency⁵. Floodplain construction subject to the UCC requires design documentation prepared and sealed by a registered design professional, and development in a Special Flood Hazard Area goes through municipal permit review^1,15. We could not confirm countywide water, sewer or private-well connection rules; ask the municipality serving the parcel.
