Do you need a building permit in Sublette County, Wyoming?

Yes—but understand what the county permit does. Unincorporated Sublette County requires a zoning and development permit before construction, including covered construction, additions, accessory structures and other regulated land development.1 The permit checks land use and development rather than building design or construction methods.1

Sublette County has not adopted or enforced the International Building Code and does not require particular structural design standards for snow or wind loads.2 That does not remove state electrical requirements, and a Wyoming electrical permit may still be necessary.2 The county also does not currently issue certificates of occupancy.11 Owners and builders therefore should treat the land-use permit and safe structural design as separate jobs: obtain county approval for the site and use, then make sure the plans satisfy every applicable state or federal requirement.1

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

The Sublette County Planning & Zoning Department is the first stop for residential and commercial building permits, zoning, subdivisions, septic permits and inspections, rural addresses and related land-use questions.7 Call the office at (307) 367-4375 or email [email protected] before finalizing a site plan.7 The office is in the Sublette County Court House at 21 S Tyler, Pinedale, WY 82941.7

For a reviewed application, the county may follow up with questions or requests for more information; after approval it issues the permit by email and posts it to the county GIS system.12 County-road maintenance belongs to Road & Bridge, while the county directs access-permit and utility-crossing questions to Planning & Zoning.13 The county has no confirmed general structural inspection requirement in the available rules, so ask Planning & Zoning which inspections apply to the specific project.7

Does Sublette County have zoning?

Yes. Sublette County zoning covers privately owned land in the unincorporated county; federal and state public lands are outside the county zoning regulations.4 Every private parcel is assigned a zoning district, and the district determines whether a proposed use is permitted, conditional or prohibited.9 Check the county GIS zoning map and confirm the use with Planning & Zoning before relying on a listing description.14

Setbacks vary by district, and accessory buildings must meet the applicable setback rules.15 Buildings in any zoning district must also stay at least 50 feet from a state or federal highway right-of-way line.15 The available material does not establish one countywide minimum home size, minimum lot size, height limit or agricultural exemption. Ask Planning & Zoning for the parcel's district standards and any conditional-use review before designing the project.7

How do septic permits work in Sublette County?

Sublette County Planning & Zoning administers small wastewater and septic permitting under a delegation agreement with Wyoming DEQ, while state sewage-disposal standards still govern the system.3 A county septic permit is required for a new system and for replacement or expansion of a septic tank or leach field.5 Systems above 2,000 gallons per day or wastewater that is not entirely domestic may need Wyoming DEQ underground-injection-control review.5

The county must inspect a permitted system, and the homeowner has 2 years after issuance to complete the project.6 Only 13.1% of mapped soils are rated without severe limitations for a conventional drain field, so make soil and wastewater feasibility an early contingency rather than assuming a standard leach field will work.16 Alternative off-grid sanitation was not confirmed; ask Planning & Zoning what design and engineering the site requires.7

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

A general rule allowing full-time RV occupancy on private land in unincorporated Sublette County could not be confirmed. Ask Planning & Zoning about the parcel's district, sanitation, temporary-use rules and any permit needed before treating an RV as housing.7 A county zoning district controls which uses are permitted, conditional or prohibited on private land.9

A tiny home is expressly covered when it is offered as a short-term rental: the structure must be lawfully permitted, must have applicable building and wastewater permits, must be in a district allowing residential use, and needs a short-term-rental permit.8 A manufactured home must meet applicable county design standards and either HUD Manufactured Home Construction and Safety Standards or the Uniform Building Code requirements specified by county regulations.17 The available rules do not establish a general minimum dwelling size, so confirm the proposed structure and occupancy directly with Planning & Zoning.7

Building a home in Sublette County: what are the steps?

  1. Identify the parcel's zoning district in the county GIS map and confirm that a dwelling is permitted or learn whether conditional approval is needed.14
  2. Ask Planning & Zoning about setbacks, floodplain constraints, addressing and the zoning and development permit package for the proposed site.7
  3. Secure legal access; a driveway connecting to a county road needs a separate access permit, while state-highway access goes through WYDOT.12
  4. Obtain an approved Wyoming groundwater permit before drilling a domestic well, and use Wyoming-licensed well and pump contractors.10
  5. Apply for the county septic permit and complete the required county inspection.56
  6. Obtain the county zoning and development permit before starting construction.1
  7. Design safely for site conditions even though the county has not adopted structural snow-load or wind-load standards.2

What should you check before buying land in Sublette County?

Start with jurisdiction and zoning: county rules cover private land in unincorporated Sublette County, while incorporated towns and public land have different authorities.4 Confirm legal access and recorded easements; Wyoming's large-parcel rule generally requires parcels of at least 35 acres to have binding, recordable ingress, egress and utility easements at least 40 feet wide to a public road unless properly waived.18

Check soils before waiving due diligence because only 13.1% of mapped soils lack severe limitations for a conventional septic drain field.16 Check the flood map as well; county rules impose a finished-floor condition on property in a floodplain.19 Water planning matters in this dry county, which averages about 18 inches of precipitation annually, and a groundwater permit must be approved before drilling.2010 Finally, verify whether a land division was lawfully approved because unincorporated-county subdivisions are regulated.21

Watch-outs

  • A county zoning and development permit is still required even though Sublette County has not adopted or enforced the International Building Code.12
  • Only 13.1% of mapped soils lack severe limitations for a conventional septic drain field, so investigate soils before committing to a house site.16
  • RV occupancy, minimum dwelling size and a general owner-builder exemption could not be confirmed; ask Planning & Zoning about the specific parcel and project.7
