Building permits in Northumberland County, Pennsylvania are required for work covered by the state Uniform Construction Code, and the issuing agency depends on the township or borough1. Zoning approval comes from the municipality, since zoning varies by township and borough rather than following one countywide ordinance2. Septic permits come from the local sewage agency serving the site, and subdivision plans go to the County Planning Commission for approval or advisory review345.

Do you need a building permit in Northumberland County, Pennsylvania?
Yes, for construction covered by Pennsylvania's Uniform Construction Code. The property owner or an authorized representative must obtain a UCC building permit before beginning covered construction or building work1. Pennsylvania's UCC applies statewide, and the owner or authorized agent must apply to the building code official and obtain the permit first; owner-builders get no general exemption from that requirement11. Municipalities generally administer it locally while opt-out municipalities use the state or certified third-party structure, so the code official and application route depend on the parcel's township or borough6. CKCOG handles UCC permits, plan review and inspections for its Northumberland County member municipalities, and it will not issue a building permit until local zoning requirements are satisfied12. UCC-regulated work requires inspections for covered construction and specified changes to residential buildings and their systems13. A residential building subject to the UCC cannot be occupied until a building code official issues the required certificate of occupancy after a compliant final inspection14.
Who issues building permits in Northumberland County, Pennsylvania, and how do you reach them?
The permit office depends on the municipality. For a CKCOG member municipality, contact Central Keystone Council of Governments at (877) 457-9401 or permits@ckcog.com, or visit 1610 Industrial Boulevard Suite 400A, Lewisburg, Pennsylvania12. In a municipality using another local or third-party code official, ask the township or borough which agency administers its UCC permits6. What stays with the county: Northumberland County's Department of Economic Development & Planning handles subdivision and land-development review and can help with planning, zoning and subdivision questions, but it does not issue building permits, zoning approval or septic permits, at 570.988.4220 or 399 Stadium Drive, Sunbury, Pennsylvania15. Published state permit fees do not establish the charge for a locally administered application; municipal and third-party enforcement agencies may use separate fee schedules16. Ask the actual code official for the current fee and required forms before submitting.
Does Northumberland County have zoning?
Zoning varies across Northumberland County: the official list separates municipalities with local zoning ordinances from municipalities without them, and the county advises checking for updates with Planning or the municipality2. Local zoning controls minimum lot area and setbacks where it exists78. Where zoning does not exist and the county SALDO applies to a subdivision or land development, minimum lot sizes depend on utilities: 6,000 square feet with central water and sewer, 15,000 with central sewer only, 30,000 with central water only, and 43,560 with on-lot water and sewer7. In that same no-zoning context, the county SALDO specifies residential setbacks of 25 feet in front, 10 feet at the side and 25 feet at the rear8. These SALDO dimensions are not a blanket rule for every existing parcel or municipality, so confirm the applicable ordinance before using them for a site plan.
How do septic permits work in Northumberland County?
On-lot sewage permitting and enforcement belong to the local agency serving the parcel, which may be a municipality, a group of municipalities or a county health agency3. That local agency issues permits for individual and community on-lot systems and retaining tanks, while large-volume systems are an exception4. Only about 7% of county soils are rated without severe limitations for a conventional drain field, so make the local sewage official's site evaluation an early purchase contingency17. We could not confirm one countywide inspection schedule; ask the township or borough which local sewage agency and Sewage Enforcement Officer serve the parcel before planning a system.
Can you live in an RV or tiny home in Northumberland County?
We could not confirm a countywide rule allowing long-term RV occupancy or tiny-home living on a single private lot in Northumberland County. The one confirmed county rule covers campgrounds and RV parks in municipalities without their own subdivision ordinance: full-time residential occupancy is not permitted, and a park needs at least 10 contiguous acres1819. The practical answer depends first on the township or borough because local zoning varies across the county2. Ask the municipality whether the parcel's district allows an RV, a tiny house on a foundation, a tiny house on wheels or temporary camping, and ask what setbacks, duration limits and utility approvals apply. A tiny home used as a residence may also require a UCC permit, inspections and a certificate of occupancy before use11314. We could not confirm a countywide rule for off-grid sanitation; ask the local sewage agency how wastewater must be handled.
What are the steps to build a home in Northumberland County, Pennsylvania?
- Identify the township or borough, then confirm its current zoning and subdivision authority with that municipality or County Planning2.
- Get zoning or land-development approval first where required; CKCOG member municipalities will not receive a building permit until zoning requirements are satisfied12.
- Contact the local sewage agency serving the parcel and complete the on-lot system review before relying on a homesite34.
- If the project creates a subdivision or land development, submit it for County Planning Commission approval or advisory review as applicable5.
- If an existing water or sewer provider will serve the development, obtain its letter of intent or executed service agreement20.
- Apply to the municipality's UCC administrator before starting covered work1.
- Arrange required inspections and obtain the certificate of occupancy before moving into the completed home1314.
What should you check before buying land in Northumberland County?
Confirm zoning, SALDO jurisdiction, lot dimensions and setbacks with the township or borough and County Planning before treating a parcel as buildable278. If a land split or development is planned, county approval or advisory review remains part of the process5. Test the proposed septic area early because only about 7% of county soils are rated without severe limitations for a conventional drain field17. For access onto a state route or highway, provide proof of a PennDOT Highway Occupancy Permit application; a municipal driveway-permit application may also be required for a borough or township street10. If any part of the project lies in a flood hazard area, the submission must document compliance with applicable municipal and state floodplain rules21. Also confirm private-well rules with the municipality; we could not confirm a countywide private-well permit rule.
Watch-outs
- Do not read 'no local zoning ordinance' as 'no land rules': county SALDO lot and setback standards can govern subdivisions and land developments where zoning does not exist78.
- The county's municipal zoning and SALDO list is subject to change, so confirm the current status with County Planning and the parcel's township or borough2.
- The owner-builder provision is not a general permit exemption; it narrowly covers specified code provisions for qualifying religious-sect applicants who apply to the code administrator9.
- A residential building subject to the UCC cannot be occupied until a building code official issues the required certificate of occupancy14.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
