Union County, PA: No Zoning, Owner-Builder Allowed

Union County, Pennsylvania property owners need a building permit before starting work covered by the statewide Uniform Construction Code¹.

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

Yes, for construction or building work covered by Pennsylvania's statewide Uniform Construction Code.

Yes, for construction or building work covered by Pennsylvania's statewide Uniform Construction Code⁸. Property owners must obtain the permit before starting covered work, although emergency repairs or equipment replacement may proceed if the application reaches the building-code official within three business days¹. CKCOG states that all Union County municipalities have adopted the state building code and will not issue a building permit until applicable zoning requirements are satisfied². Inspections are required for covered residential construction and for changes involving electrical, gas, mechanical, or plumbing systems¹. A certificate of occupancy is required before a covered building or facility can be used¹. A qualifying agricultural building is excluded from the state Construction Code Act, but that exclusion does not erase municipal zoning, health, environmental, or other applicable rules⁹.

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

Start with Central Keystone Council of Governments, the building-code contact shown for Union County municipalities.

Start with Central Keystone Council of Governments, the building-code contact shown for Union County municipalities. CKCOG's Union County page gives 1610 Industrial Boulevard, Suite 400A, Lewisburg, PA 17837; phone 570-522-1326, option 2; and permits@ckcog.com². The same page places zoning approval before the building permit and requires inspections for permitted construction². Ask CKCOG which forms, exemptions, and local fees apply. Pennsylvania publishes a Department of Labor and Industry fee schedule for permits the Department issues, but municipal or third-party charges may differ¹⁰. No general owner-builder waiver from permits or inspections was confirmed. A narrow exemption from conflicting electrical, qualifying lumber or wood, or plumbing provisions is available to qualifying members of recognized religious sects who submit the required affidavit; it is not a blanket permit exemption⁶. For municipal zoning questions where no officer is listed, CKCOG directs readers to the Union County Planning Commission at the UC Government Center in Lewisburg, phone (570) 524-3840².

Does Union County have zoning?

Treat zoning as a township-or-borough question, not a single countywide answer.

Treat zoning as a township-or-borough question, not a single countywide answer. Union County municipalities differ: the official directory identifies zoning ordinances for some and expressly lists no zoning for others². CKCOG's Union County directory lists different zoning contacts and says to call the Union County Planning Commission when no zoning officer is listed². We could not confirm one operative countywide rule that answers every parcel's use, setback, minimum-lot-size, building-height, or minimum-home-size question. Before designing a house or making an offer, identify the parcel's municipality and request its current ordinance, zoning map, dimensional table, and written interpretation for the intended use. Pennsylvania law allows county zoning only in municipalities lacking their own zoning ordinance and only until a municipal ordinance takes effect¹¹.

How do septic permits work in Union County?

On-lot sewage regulation is shared: Pennsylvania DEP oversees the program, while local agencies employ Sewage Enforcement Officers and handle permitting and enforcement.

On-lot sewage regulation is shared: Pennsylvania DEP oversees the program, while local agencies employ Sewage Enforcement Officers and handle permitting and enforcement³. Local agencies issue permits for most retaining tanks and individual or community on-lot systems; large-volume systems are an exception⁴. Contact the parcel's township or borough for its current Sewage Enforcement Officer, or use DEP's active-officer directory by county¹². Obtain approval before installing the system or occupying the building it serves¹³. The state rule includes a conditional exemption for an owner or immediate-family residence on a contiguous tract of at least 10 acres, subject to notice, siting, ownership-date, and local-ordinance conditions¹³. Only 18.5% of Union County soils lack severe limitations for a conventional drain field, so make sewage feasibility a purchase contingency¹⁴.

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

We could not confirm a countywide rule allowing long-term RV occupancy or tiny-home occupancy on private land in Union County.

We could not confirm a countywide rule allowing long-term RV occupancy or tiny-home occupancy on private land in Union County. Ask the parcel's township or borough zoning contact about the proposed dwelling, duration, utilities, and use during construction because zoning varies by municipality². East Buffalo Township's rule for recreational-vehicle parks allows only intermittent recreational use and prohibits full-time residential occupancy within those parks; it does not answer whether an RV may be occupied elsewhere on private land¹⁵. Pennsylvania state-forest roadside camping is also temporary: it requires a designated site and permit, with stays capped at seven consecutive nights and a 48-hour vacancy before reapplying¹⁶. That camping rule does not authorize residential RV use on private land. A manufactured home is not a shortcut around site rules; utility connections, additions, relocation, resale, and some occupancy changes can trigger the Uniform Construction Code¹⁷.

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

Identify the parcel's township or borough and ask for its zoning contact, current ordinance, and parcel-specific dimensional rules.

Identify the parcel's township or borough and ask for its zoning contact, current ordinance, and parcel-specific dimensional rules².

Obtain any required zoning approval first; CKCOG says it will not issue the building permit until zoning requirements are satisfied².

Contact the local Sewage Enforcement Officer and secure the required on-lot sewage approval before relying on the site as buildable⁴.

Ask CKCOG for the applicable forms and local fees, then obtain the Uniform Construction Code building permit before covered work begins^1,2.

Schedule each required inspection during construction¹. If access involves state-highway land or a PennDOT drainage facility, obtain the separate highway occupancy permit¹⁸.

Obtain the Uniform Construction Code certificate of occupancy before using the completed building or facility¹.

What should you check before buying land in Union County?

Confirm zoning, legal access, sewage feasibility, water, and floodplain status before closing.

Confirm zoning, legal access, sewage feasibility, water, and floodplain status before closing. A state-highway driveway or work connecting to PennDOT drainage requires a highway occupancy permit¹⁸. Development inside a Special Flood Hazard Area requires a municipal floodplain-development permit before work begins¹⁹. For water, Pennsylvania licenses and permits commercial well drillers but exempts a farmer or homeowner drilling a well on owned or leased land from that licensing requirement; we could not confirm a separate Union County well-permit rule⁷. The land itself is mixed: 62.3% has a slope of 15% or less, while only 18.5% of soils lack severe conventional-drain-field limitations¹⁴. Typical farmland value is about $12,462 per acre, but parcel price and suitability can differ sharply¹⁴.

Watch-outs

Do not start covered work before the building permit is issued; the emergency-repair exception still requires an application within three business days¹.
Private-land RV living, tiny-home occupancy, setbacks, and minimum dwelling size were not confirmed countywide; zoning varies by municipality, so ask the parcel's township or borough for a written answer².
Most Union County soils have severe limitations for a conventional septic drain field, so do not treat acreage alone as proof that an on-lot system will work¹⁴.

Who permits septicMixed (with conditions)
Statewide regulation and administration of on-lot sewage facilities and septic systems in Pennsylvania.
- On-lot sewage permitting and enforcement are largely administered by local agencies, including individual municipalities, groups of municipalities, county departments of health, and joint county departments of health.
- Local agencies issue permits for retaining tanks and individual or community on-lot sewage systems that renovate sewage effluent in a soil absorption area or spray field.
- Large volume on-lot systems are an exception to the local-agency permitting responsibility identified on the DEP page.
- DEP provides technical oversight and financial assistance to local agencies.
- Delegated joint local agencies may receive additional DEP authority to review and approve or disapprove new land-development sewage-planning proposals, and depending on the delegation may process both on-lot and public sewerage proposals.
“Local Agencies are responsible for carrying out on-lot or onsite ("septic system") sewage treatment system permitting and enforcement activities. With certain exceptions (i.e. large volume on-lot systems), local agencies are responsible for issuing permits for retaining tanks or for individual and community on-lot sewage systems which renovate sewage effluent in a soil absorption area or spray field.
