Project questions
Frequently asked questions for Northumberland County
Who handles permitting for this jurisdiction?
This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.
How should I begin an application?
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact Northumberland County Planning Commission: 570-988-4220; county administration: 570-988-4100; local building-code agency varies.
How long might review take?
N/A countywide for building permits; Pennsylvania UCC generally requires a code official to grant or deny a complete application within 30 business days, while municipal or third-party review timing varies.
How are inspections scheduled?
Contact the municipality where construction will occur to identify its Building Code Official or certified third-party agency, submit the UCC application and plans, and schedule required inspections. The county Planning Commission handles county planning, subdivision/land-development, and municipal support questions at 570-988-4220; it does not schedule countywide building inspections.
Which codes and exemptions should I review?
Pennsylvania Uniform Construction Code (UCC), 34 Pa. Code Chapters 401-405 and referenced current ICC codes as adopted by Pennsylvania, including applicable 2021 ICC editions for 2026 permits. The county's hazard mitigation plan states that most municipalities adopted the UCC; opted-in municipalities use local or third-party code officials, while Pennsylvania Labor and Industry retains responsibility in opted-out municipalities and for state-owned buildings. No countywide building-permit exemption list was identified because Northumberland County does not issue countywide building permits. UCC exemptions and permit thresholds are administered by each municipality or designated code agency; emergency repairs or equipment replacements may proceed without advance permitting only when the UCC application is submitted to the building code official within three business days. Other minor-work exemptions vary locally and do not remove zoning, floodplain, sewage, stormwater, driveway, or other approvals.
