Do you need a building permit in Greene County, Pennsylvania?
Yes for work covered by Pennsylvania's Uniform Construction Code: a UCC building permit must be obtained before covered work begins11. Builders throughout Greene County must follow Pennsylvania's statewide UCC, while municipalities may administer it themselves or use certified third-party agencies1. Washington Township, for example, publishes separate zoning and UCC building-code contacts12. A residential building subject to the UCC cannot be occupied until a building code official issues a certificate of occupancy13. A qualifying agricultural building used for covered farm purposes and containing no habitable space is excluded from the state Construction Code Act, although zoning, electrical, health, and other requirements may still apply9. Greene County's sources do not confirm a general owner-builder exemption, so an owner acting as contractor should ask the applicable UCC administrator before assuming the permit requirement changes8.
Who issues building permits in Greene County, and how do you reach them?
Start with the township or borough containing the parcel. Pennsylvania allows municipalities that administer the UCC to use their own staff or certified third-party agencies; where a municipality opts out, certified third-party agencies handle residential UCC enforcement and the Department of Labor and Industry handles specified commercial enforcement6. Washington Township illustrates the local setup: its official page lists a zoning and code-enforcement contact and a separate company for UCC and building-code inspection12. That office is an example for Washington Township only, not the contact for every Greene County parcel12. For a subdivision, lot split, or land-development question, the Greene County Planning Commission publishes county land-development resources and states that it reviews land developments and subdivisions14. Pennsylvania law also allows a municipal subdivision ordinance to control locally and allows a county ordinance to apply where a municipality has none, so confirm the review path for the parcel with both the municipality and county planning office15.
Does Greene County have zoning?
There is no single zoning answer for every parcel in Greene County. The county plan says only eight of Greene County's twenty-six municipalities had zoning regulations in place as of January 2025; some municipalities have subdivision or land-use ordinances, some have zoning, some have both, and some have neither3. Washington Township has A-1 Rural Agricultural, R-1 Suburban Residential, C-1 Commercial, and I-1 Industrial districts on its published zoning map16. A separate Jefferson-Morgan multi-municipal zoning ordinance was enacted by four municipalities, although the reviewed county document does not name those municipalities or list their districts17. Minimum lot area, setbacks, lot coverage, building height, and the siting of RVs, tiny homes, manufactured homes, or accessory dwellings therefore require a parcel-specific answer from the relevant township or borough7. The Greene County Planning Commission can help with subdivision and land-development review14.
How do septic permits work in Greene County?
The responsible local agency issues permits for individual and community on-lot sewage systems in Greene County, generally through the municipality's Sewage Enforcement Officer45. Washington Township publishes its own sewage officer, but land outside Washington Township needs the SEO for the correct township or borough18. Pennsylvania generally requires the local permit before installation, construction, occupancy, or use of a building served by an on-lot system19. A narrow exemption may apply to an owner or immediate-family residence on a contiguous tract of at least 10 acres, but owner-of-record, notice, local-ordinance, and siting conditions still control19. Do not assume acreage alone qualifies a parcel. Greene County soils make early testing especially valuable: only 0.2% of county soils are rated without severe limitations for a conventional drain field20. For a new home using a composting or incinerating toilet, Pennsylvania still requires an approved way to treat washwater or excess liquid21.
Can you live in an RV or tiny home on your land in Greene County?
Greene County has no confirmed uniform countywide rule that answers long-term RV living, temporary camping on private land, tiny-home occupancy, or minimum dwelling size. The practical answer depends first on whether the parcel's township or borough has zoning, because municipal zoning varies across Greene County7. Ask that municipality whether the proposed unit is treated as a dwelling, recreational vehicle, manufactured home, or accessory structure, and ask its UCC administrator what construction and occupancy approvals apply226. Pennsylvania's published stay limits for state park campgrounds do not establish permission to occupy an RV on private land23. A manufactured home follows separate state rules: site preparation, utility connections, additions, repairs, relocation, or a change of occupancy can bring UCC requirements into play, while local siting and zoning remain separate questions24. Before buying for either use, get the township or borough's answer in writing and confirm an approvable sewage plan with its SEO4.
Building a home in Greene County: the steps, in order
- Identify the parcel's township or borough, then ask that municipality who administers zoning and residential UCC permits226.
- Confirm the proposed use, setbacks, access, and any local dimensional rules before designing the home, because zoning differs among Greene County municipalities7.
- Contact the municipality's Sewage Enforcement Officer for site testing and the on-lot permit; difficult soils make this an early feasibility step420.
- If the project includes a lot split or land development, confirm the approval route with the municipality and Greene County Planning Commission1415.
- Obtain the UCC building permit before covered work starts11.
- Obtain a municipal floodplain development permit before work in a Special Flood Hazard Area25.
- Obtain a PennDOT Highway Occupancy Permit if a new or changed driveway touches state-highway land or connects to PennDOT drainage26.
- Complete required inspections and obtain the certificate of occupancy before using a residential building subject to the UCC13.
What should you check before buying land in Greene County?
Put septic feasibility near the top of the due-diligence list: only 0.2% of Greene County soils are rated without severe limitations for a conventional drain field20. Terrain can compound the site-work question, because 38.4% of county land has a slope of 15% or less and 73.5% is wooded2728. Confirm municipal zoning, subdivision history, mapped flood hazard, and legal road access before closing7152526. For water, Pennsylvania requires commercial water-well drillers to hold state licensing and permits, while the licensing requirement does not apply to a homeowner or farmer drilling a well on owned or leased land; Greene County-specific private-well permitting was not confirmed, so ask the municipality and proposed driller what approvals apply10. As price context rather than a parcel appraisal, the county's typical home value is about $157,805, USDA farmland value is about $5,257 per acre, the effective property-tax rate is about 1.3%, and the median annual property-tax bill is about $1,89329303132.
Watch-outs
- Do not treat Washington Township's four zoning districts or its contacts as countywide; Greene County municipalities differ in zoning and local administration1612.
- A large tract is not automatically exempt from a septic permit; Pennsylvania's exemption has ownership, family-use, notice, local-ordinance, and siting conditions19.
- A public electric or gas utility cannot connect completed construction subject to the UCC without written proof that required inspections passed33.
