Do you need a building permit in Beaver County, Utah?
Yes. Unincorporated Beaver County requires the owner or authorized agent to obtain a permit before covered construction, enlargement, alteration, repair, moving, demolition, occupancy changes, or regulated electrical, gas, mechanical, and plumbing work1. Exempt work includes a single-story detached storage shed or playhouse no larger than 200 square feet, a fence no higher than 7 feet, and a retaining wall no higher than 4 feet, subject to the claim's stated conditions1. Adding electrical to an otherwise exempt accessory structure still requires a permit1. Utah's agricultural construction-code exemption can cover a structure used solely for agriculture and not for human occupancy, but plumbing, electrical, or mechanical work may still need permits and the exemption narrows on certain smaller tracts8.
Who is the Beaver County building department, and how do you reach it?
The Beaver County Building Department handles permits and inspections for unincorporated Beaver County at 105 East Center Street in Beaver and can be reached at (435) 438-64849. For an unincorporated parcel beginning with 01- or 02-, the department handles zoning, the permit application, payment, and inspection scheduling29. Incorporated Beaver City handles its own zoning and permit applications, while Minersville and Milford handle parts of zoning or payment and contract other building functions through the county10. Published electrical, mechanical, plumbing, and roofing permits cost $75.75, while new-home and commercial fees depend on building area and project value11. Required inspections need at least 24 hours' notice129.
Does Beaver County have zoning?
Yes. Beaver County administers zoning for unincorporated parcels whose parcel numbers begin with 01- or 02-2. Incorporated Beaver City, Minersville, and Milford have separate zoning arrangements, so a municipal parcel should not be treated as though the unincorporated-county rules control it10. Standards depend on the zoning district: in the Forest/Recreation Residential districts, FR-1 requires at least 1 acre and 120 feet of width, while FR-.5 requires at least 0.5 acre and 80 feet of width13. Those districts also have specific front, side, and rear setbacks rather than one countywide setback14. The county's online zoning map is informational, may change, and should be verified with the appropriate authority before a purchase or building decision15.
How do septic permits work in Beaver County?
Southwest Utah Public Health Department is the septic authority for Beaver County, and its Environmental Health program reviews plans, issues permits, conducts inspections, and keeps system records316. Call the Beaver and Garfield County septic contact at (435) 865-515816. A permit and approved design are required before installing, replacing, or modifying a septic system, and soil and percolation testing must be completed by a Utah-certified onsite professional17. Every septic system needs a final inspection before backfilling18. Only 37.1% of Beaver County soils avoid severe USDA limitations for a conventional drain field, so make septic feasibility part of the land evaluation rather than assuming a standard system will work7. Off-grid wastewater may use an approved onsite system, but it remains subject to district permitting and inspection19.
Can you live in an RV or tiny home on your land in Beaver County?
Beaver County does not allow a travel trailer as permanent living quarters outside an approved and licensed travel-trailer park4. A property owner may seek a temporary-use permit in listed zoning districts for the period from May 1 through October 31, limited to 180 days in a calendar year, with a new permit required each year4. That temporary residence also needs approved septic, culinary water, fire protection, and power4. The reviewed research did not locate a Beaver County provision specifically defining tiny-home occupancy, so confirm how a proposed unit will be classified with the Building Department before buying or placing it. A detached accessory dwelling unit must be permanent; a trailer, mobile home, or other portable wheeled structure cannot qualify as one20.
Building a home in Beaver County: the steps, in order
- Identify whether the parcel is unincorporated from its parcel number, then confirm the zoning district and allowed dwelling type with the Beaver County Building Department29.
- Verify lot area, width, setbacks, and access rules for that district; Forest/Recreation Residential standards, for example, vary between FR-1 and FR-.51314.
- Secure a water source; a private well requires a valid water right and state permission to drill6.
- Obtain the septic permit and approved design before installation, then leave the system uncovered for its final inspection1718.
- Apply for the building permit before covered work starts21.
- Schedule each required county inspection with at least 24 hours' notice and do not cover work until approved12.
What should you check before buying land in Beaver County?
Start with jurisdiction and zoning because Beaver County handles unincorporated parcels differently from Beaver City, Minersville, and Milford10. Verify septic feasibility early because only 37.1% of county soils avoid severe limitations for a conventional drain field7. Confirm legal water before assuming a well is available, since groundwater use and drilling require a valid water right and state approval6. If access connects to a state highway, a UDOT conditional access permit is required for a new driveway connection or a change in access intensity22. Beaver County averages 2.8 people per square mile, and 76.7% of its land is federally owned, figures that help explain why parcel access and neighboring public land deserve close title and map review2324. The effective property-tax rate is about 0.4%, with a median annual bill of $1,1212526.
Watch-outs
- A small accessory building may be permit-exempt, but adding electrical work triggers a permit1.
- The Utah owner-builder exemption concerns contractor licensing only; Beaver County permits, inspections, zoning, and other requirements still apply5.
- County driveway rules and floodplain-development permitting remain unconfirmed; ask the Building Department about both before designing access or building in a mapped flood area9.
