Lincoln County, Wyoming requires a building permit for a new home, and the county Planning & Development Office provides the residential application1. The same office administers zoning, small-wastewater (septic) permits and inspections, and floodplain matters1,2. Septic digging is barred from November 15 through April 1, so winter planning matters3.
Do you need a building permit in Lincoln County, Wyoming?
Yes.
Yes. Lincoln County requires a building permit for a new home, and its document center provides a residential building-permit application for new homes and additions1. The county's published material does not fully establish which other projects require permits, which building-code edition applies, or whether building inspections and a certificate of occupancy are required. Ask Lincoln County Planning & Development about the exact project before ordering materials; the office handles building and permitting questions1. No owner-builder exemption was confirmed, so building your own house should not be treated as an exemption from the county permit process4. Occupancy is a state matter: newly built or remodeled buildings subject to the state fire-safety statute cannot be used or occupied until the state fire marshal issues a certificate of occupancy or letter of compliance, subject to statutory exceptions4. Wyoming law allows county building-code enforcement only after the state fire marshal delegates authority to a county that maintains qualifying standards and inspectors6.
Who is the Lincoln County building department, and how do you reach it?
Lincoln County's Office of Planning & Development is the first stop for building, land-use, zoning, subdivision, septic and floodplain questions.
Lincoln County's Office of Planning & Development is the first stop for building, land-use, zoning, subdivision, septic and floodplain questions1. The Kemmerer office is at 925 Sage Avenue, Suite 201, Kemmerer, WY 83101; call (307) 877-9056 or email planning@lincolncountywy.gov1. The county accepts permit applications through its online portal1. The portal and document center are useful starting points, but the reviewed county pages do not establish complete submittal requirements or review times1. Send the parcel number, proposed use and a short project description when asking which forms are needed, because one office coordinates several different approvals1.
Does Lincoln County have zoning?
Yes.
Yes. Lincoln County administers zoning and its Land Use Regulations through county planning processes1. Wyoming law authorizes county commissioners to regulate building locations, land uses and occupancy in unincorporated areas, without overriding an incorporated city or town's zoning authority7. That distinction matters: a parcel inside Kemmerer, Afton or another municipality may follow municipal rules rather than the county rules described here7. The available facts do not confirm a parcel's minimum lot size, setbacks, lot coverage, building height or minimum dwelling size. Lincoln County Planning & Development should identify the zone and applicable dimensional standards before a buyer relies on a listing's claim that land is buildable1. County subdivision applications also vary by category, including major, minor, simple, amended-plat and phased processes1.
How do septic permits work in Lincoln County?
Lincoln County requires a septic permit for the installation, repair or replacement of a small wastewater system (septic tank and leach field), and construction may not start until authorization is issued.
Lincoln County requires a septic permit for the installation, repair or replacement of a small wastewater system (septic tank and leach field), and construction may not start until authorization is issued3. Lincoln County Planning & Development administers that permitting and inspection1. Digging for septic systems is barred in the county from November 15 through April 1, so a fall start needs a finished permit and a plan for the spring3. Wyoming DEQ directly permits small wastewater facilities in only specified jurisdictions and warns that other permitting authorities may use different forms or request more information8. Site conditions deserve early attention: only about 9.7% of Lincoln County soils are rated without severe limitations for a conventional septic drain field9. That soil rating does not decide whether a particular lot will pass, but it makes a parcel-specific site evaluation a prudent early step. County Planning & Development handles the local septic and inspection questions at the same contact used for building permits1.
Can you live in an RV or tiny home on your land in Lincoln County?
We could not confirm a county rule that generally allows or prohibits living in an RV on private land in Lincoln County, and the available material does not establish a rule for temporary camping.
We could not confirm a county rule that generally allows or prohibits living in an RV on private land in Lincoln County, and the available material does not establish a rule for temporary camping. We also could not confirm county occupancy standards for a tiny home, manufactured home or accessory dwelling. Lincoln County does have zoning, so the answer may depend on the parcel's zone and the way the proposed unit is classified1. Before buying, ask Lincoln County Planning & Development in writing whether the proposed use is allowed, whether a temporary-use approval is needed, and which building and sanitation approvals apply1. A tiny home intended as a dwelling should not be assumed exempt from the residential building-permit process merely because it is small1.
Building a home in Lincoln County: the steps, in order
Ask Lincoln County Planning & Development to confirm the parcel's jurisdiction, zone, allowed residential use and dimensional standards.
- Ask Lincoln County Planning & Development to confirm the parcel's jurisdiction, zone, allowed residential use and dimensional standards1.
- Resolve access and subdivision issues early; regulated subdivisions need county approval, while qualifying parcels of 35 acres or more generally require recorded access and utility easements at least 40 feet wide to a public road unless properly waived1,10.
- Apply to Wyoming for well approval before drilling; domestic and stock applications carry a $50 filing fee5.
- Have the site evaluated, get the county septic permit, and schedule inspections with county Planning & Development; no septic digging is allowed November 15 through April 11,3.
- Ask whether the site needs a floodplain development permit before moving dirt or placing a structure2.
- Submit the residential building-permit application through the county's online portal and confirm any required inspections directly with the office1.
- Before moving in, ask the state fire marshal about the certificate of occupancy or letter of compliance4.
What to check before you buy land in Lincoln County
Start with jurisdiction and zoning: county rules govern unincorporated land, while incorporated places can use their own zoning.
Start with jurisdiction and zoning: county rules govern unincorporated land, while incorporated places can use their own zoning7. Check water before closing because Wyoming requires an approved groundwater permit before drilling a well or developing a qualifying spring5. Check soils early because only about 9.7% of county soils are rated without severe limitations for a conventional drain field9. Check terrain and winter access on the actual parcel; about 55% of county land has a slope of 15% or less, but a countywide figure cannot describe one lot9. Confirm floodplain status and any development permit with Planning & Development1,2. Verify legal access, especially on large tracts subject to Wyoming's recorded-easement rule10. For carrying costs, the effective property-tax rate is about 0.4%, and the median annual property-tax bill is about $1,4589.
Watch-outs
- Only about 9.7% of Lincoln County soils are rated without severe limitations for a conventional septic drain field, so investigate the specific homesite before assuming a standard system will work9.
- Lincoln County's reviewed material does not confirm the rules for RV living, tiny-home occupancy, minimum dwelling size or setbacks; ask Planning & Development about the parcel and proposed use1.
- A parcel inside an incorporated city or town may be subject to municipal zoning rather than Lincoln County's unincorporated-area rules7.
- The county no-dig period, November 15 through April 1, applies to septic systems and digging in the county right-of-way1.
