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

Yes, for construction or building work covered by Pennsylvania's statewide Uniform Construction Code11. 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 systems6. A certificate of occupancy is required before a covered building or facility can be used10. 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 rules12.

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. 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 differ13. 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 exemption8. 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) 524-384014.

Does Union County have zoning?

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 others3. CKCOG's Union County directory lists different zoning contacts and says to call the Union County Planning Commission when no zoning officer is listed214. 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 effect15.

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 enforcement4. Local agencies issue permits for most retaining tanks and individual or community on-lot systems; large-volume systems are an exception5. Contact the parcel's township or borough for its current Sewage Enforcement Officer, or use DEP's active-officer directory by county16. Obtain approval before installing the system or occupying the building it serves17. 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 conditions17. Only 18.5% of Union County soils lack severe limitations for a conventional drain field, so make sewage feasibility a purchase contingency18.

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. Ask the parcel's township or borough zoning contact about the proposed dwelling, duration, utilities, and use during construction because zoning varies by municipality3. 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 land19. 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 reapplying20. 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 Code21.

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

  1. Identify the parcel's township or borough and ask for its zoning contact, current ordinance, and parcel-specific dimensional rules3.
  1. Obtain any required zoning approval first; CKCOG says it will not issue the building permit until zoning requirements are satisfied2.
  1. Contact the local Sewage Enforcement Officer and secure the required on-lot sewage approval before relying on the site as buildable5.
  1. Ask CKCOG for the applicable forms and local fees, then obtain the Uniform Construction Code building permit before covered work begins21.
  1. Schedule each required inspection during construction6. If access involves state-highway land or a PennDOT drainage facility, obtain the separate highway occupancy permit22.
  1. Obtain the Uniform Construction Code certificate of occupancy before using the completed building or facility10.

What should you check before buying land in Union County?

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 permit22. Development inside a Special Flood Hazard Area requires a municipal floodplain-development permit before work begins23. 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 rule9. 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 limitations2418. Typical farmland value is about $12,462 per acre, but parcel price and suitability can differ sharply25.

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 answer3.
  • 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 work18.

Union County rules

  • Local zoningVaries (with conditions)

    Aggregate zoning status across Union County townships and boroughs; the actual rule-maker is the applicable municipality.

    • Requirements depend on the municipality and its adopted ordinance.
    • The official county directory lists zoning ordinances for some municipalities and expressly lists zoning as none for others.
    • The county-level conclusion does not mean Union County administers each municipal zoning ordinance.
    “Township Subdivision/Township Zoning/Comprehensive Plan [...] MUNICIPAL ORDINANCES Township Subdivision Zoning - None”
  • County-wide zoningAbsent

    Zoning in Pennsylvania is administered at the municipal level; several Union County municipalities (e.g. Union Township, East Buffalo Township) have adopted zoning ordinances, and zoning approval is a pre-construction requirement, coordinated via the Union County Planning Department.

  • 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. [...] In some cases, Joint Local Agencies may obtain additional authority and responsibility from DEP by requesting Act 537 planning approval delegation.”
