Northumberland County, PA Building Permits & Zoning

Northumberland County, Pennsylvania has no countywide zoning ordinance; zoning is set township by township and borough by borough among the county's 36 municipalities, and some have none at all¹. A building permit is still required everywhere in the county, issued through the Central Keystone Council of Governments (CKCOG) under Pennsylvania's Uniform Construction Code, but CKCOG will not issue it until your municipality's zoning requirements, if any, are satisfied². Septic permits come from your municipality's own Sewage Enforcement Officer under the state's Act 537 program, not from the county³.

Do you need a building permit in Northumberland County, Pennsylvania?

Yes, everywhere in the county. Pennsylvania's statewide Uniform Construction Code (UCC) applies, and in Northumberland County it is administered by the Central Keystone Council of Governments (CKCOG) on behalf of the county's member municipalities². CKCOG's own process states plainly that building permits will not be issued until all zoning requirements have been satisfied, so your first stop is your township or borough's zoning office, not CKCOG, if your municipality has one⁹. Depending on the project you may also need water/sewer connection approval from your municipality, a driveway permit from your municipality or PennDOT, subdivision or land development plan approval, a valid street address from the county's GIS office, and an elevation certificate if you're in a designated flood management area⁹. Buildings used primarily for agricultural purposes, such as a structure to store hay, feed or grain or house livestock, are excluded from the state Construction Code Act, though other municipal rules can still apply to them¹⁰.

Who issues building permits in Northumberland County, and how do you reach them?

Central Keystone Council of Governments (CKCOG) issues Uniform Construction Code permits for Northumberland County's member municipalities; reach them toll-free at (877) 457-9401 or by email at [email protected], at 1610 Industrial Boulevard Suite 400A, Lewisburg⁹. For zoning questions, and for the county's own Subdivision & Land Development Ordinance, contact the Northumberland County Department of Economic Development & Planning at 570.988.4220, 399 Stadium Drive, Sunbury¹¹. Because zoning and building-permit prerequisites are set locally, CKCOG directs applicants to click through to their specific municipality to find that municipality's own zoning contact and requirements before applying for the building permit itself⁹.

Does Northumberland County have zoning?

Not at the county level. Northumberland County has no countywide zoning ordinance; instead, each of the county's 36 townships and boroughs decides for itself, and the county's own Planning Department publishes a list showing exactly which ones have adopted local zoning and which have not¹⁴. Coal Township, Delaware Township, East Chillisquaque Township, Lewis Township, Lower Augusta Township and Milton Borough are examples of municipalities with their own local zoning ordinance, while East Cameron Township, Herndon Borough, Jackson Township, Jordan Township, Kulpmont Borough and Little Mahanoy Township are examples with no zoning ordinance at all⁴. Pennsylvania law does let a county zone land in a municipality that has no zoning ordinance of its own, but only until that municipality adopts one, so a county rule would only ever be a stand-in, not a substitute, for local zoning¹². The same pattern applies to subdivision and land development: a municipality without its own Subdivision & Land Development Ordinance falls back to the county's, per that same list⁴. This list can change, so confirm your specific township or borough's current status with the county Planning Department before you buy¹¹.

How do septic permits work in Northumberland County?

Septic permits in Northumberland County come from your municipality's own Sewage Enforcement Officer (SEO), a joint local agency function required statewide under Pennsylvania's Act 537, not from the county³. Pennsylvania requires a permit from that local agency before you install, build toward, occupy or use a building served by an individual or community onlot sewage system¹³. Only about 7% of Northumberland County's soils are rated free of severe limits for a conventional septic drain field, so plan on the SEO's site evaluation shaping what kind of system you can install¹⁴. There is a narrow statewide exemption from the permit for an individual system serving an owner or immediate family on a contiguous tract of at least 10 acres, but it comes with owner-of-record, siting and notification conditions, so confirm it applies to your specific situation before assuming you're exempt¹³. Once your system is built, it legally cannot be covered until the permit-issuing agency gives approval to cover it¹⁵.

Can you live in an RV or tiny home on your land in Northumberland County?

Whether you can depends entirely on your specific township or borough, because Northumberland County has no countywide zoning and several of its municipalities do have their own zoning ordinance¹⁴. Pennsylvania's state park rules cap RV camping at 14 consecutive nights from Memorial Day to Labor Day and 21 nights the rest of the year, but that only governs state park campgrounds, not private land, so it does not answer whether you can live in an RV on your own parcel¹⁶. A manufactured home is treated differently once it leaves the factory: if it's installed exactly to the manufacturer's approved design it's largely outside the Uniform Construction Code, but any later alteration, addition, resale-related change, or relocation brings it back under the UCC, on top of whatever your municipality's zoning says about where a manufactured home can sit¹⁷. Call your specific township or borough zoning office, or the county Planning Department if your municipality doesn't list one, before you buy or move a unit onto the land¹¹.

Building a home in Northumberland County: the steps, in order

Identify your township or borough and check the county's zoning and SALDO list to see whether it has a local zoning ordinance, a local Subdivision & Land Development Ordinance, or falls back to the county's⁴.
If your municipality has zoning, get your zoning permit and any required site plan from that municipality before applying for a building permit; CKCOG will not issue the building permit until zoning is satisfied⁹.
Line up septic: apply to your municipality's Sewage Enforcement Officer, since Northumberland County itself does not issue septic permits³.
Confirm your other prerequisites: water or sewer connection approval from your municipality, a driveway permit from your municipality or PennDOT, a valid street address from the county's GIS office, and an elevation certificate if you're in a mapped flood area⁹.
Apply for your Uniform Construction Code building permit through Central Keystone Council of Governments, (877) 457-9401 or [email protected]⁹.
If your driveway or access will connect to a state highway, apply separately for a PennDOT Highway Occupancy Permit; PennDOT usually issues it within 30 days of a complete application⁷.

What to check before you buy land in Northumberland County

Confirm your specific township or borough's zoning status first: Northumberland County's own list shows some municipalities with zoning and some with none, and that mix directly changes what you can build and where⁴¹. Budget for septic carefully: with only about 7% of the county's soils rated free of severe limits for a conventional drain field, get your municipality's Sewage Enforcement Officer or a private evaluation done before you're committed to the purchase¹⁴. About 62% of the county's land sits at 15% slope or less, so most parcels are buildable on grade, but confirm the specific site¹⁸. Typical property tax runs about 1.2% of value, with a median annual bill near $1,778, while a typical home insurance premium here runs about $871 a year¹⁹²⁰²¹. Farmland in the county has been valued around $8,292 an acre and the typical home value is about $176,960²²²³. The nearest city of 100,000 or more people is roughly 67 miles from Northumberland County's center⁸.

Watch-outs

Northumberland County's zoning and SALDO list itself warns that it can change, and recommends confirming with the county Planning Department and your specific municipality before relying on it⁴.
Because zoning here is set township by township and borough by borough, never assume 'Northumberland County has no zoning' means your specific parcel is unrestricted; several of the county's 36 municipalities have adopted their own zoning ordinance¹⁴.
A building permit will not be issued until local zoning requirements are satisfied, so start with your municipality, not directly with the building-permit agency⁹.
