Building permits, zoning and land rules in Albany County, Wyoming

Albany County, Wyoming has no county building code; the applicable county construction approval on unincorporated land is a zoning certificate, rather than a separate building-code permit^1,2. A certificate generally must be obtained before construction, placement, enlargement or a change of use². Exceptions include accessory buildings of 144 square feet or less, structures onsite no longer than six months, and internal reconstruction that does not change the use². We could not confirm general structural-inspection or certificate-of-occupancy requirements; ask Albany County Planning what review applies⁷. The county application allows self-built homes, but owners still submit the zoning application, fee, ownership proof and site plan⁸.

Albany County Planning handles zoning certificates for unincorporated projects at 1002 S 3rd Street in Laramie; call 307-721-2568 before beginning work⁷. Albany County does not issue a separate building-code permit^1,2. The zoning-certificate application requires the form, fee, ownership evidence, site plan, and applicable easements or approach licenses⁹. Planning reviews zoning applications and wastewater applications, with wastewater construction permission followed by approval before backfill¹. Published fees include $750 for a conditional use, $500 for a variance and $400 for floodplain development¹⁰. Fees may be revised, and zoning applications can incur a $200 late fee for construction before approval; confirm the current charge for the specific application with Planning¹⁰.

Albany County zoning covers unincorporated land, with state and federal lands exempt; Laramie sets its own zoning inside city limits^2,4. Small-wastewater permitting inside Laramie remains with Albany County under Wyoming DEQ delegation, with city-sanitarian inspection; larger systems or systems connected to more than one structure go through DEQ⁶. Use the county zoning map to identify the parcel’s district before choosing a house site². Minimum lots are 35 acres in Agricultural, 10 acres in Agricultural Residential, 5 acres in Rural Residential, and 2 acres in Ranchette and Small Lot Residential¹¹. Minimum lot size is not dwelling density: Agricultural Residential allows one principal dwelling per 20 acres, Rural Residential per 10 acres, and Ranchette per 5 acres¹¹. Setbacks vary by district and use, with wastewater setbacks governed separately². Neighborhood Business lots must fit water and wastewater systems within setbacks; Industrial lots have a 1-acre minimum¹¹.

Albany County Planning’s Assistant Planner - Environmental administers small-wastewater permits; installing, repairing or modifying a system requires an application, fees payable by cash/check, and plans, specifications or design data³. Obtain the Authorization to Construct letter before construction, and arrange inspection before backfilling⁵. The completed system cannot be covered or used until inspection and approval⁶. A licensed installer normally performs the work, although owners may install their own system under county guidance³. Confirm the current septic fee with Planning because published fee entries differ^10,12. Only 28.9% of Albany County soils are rated without severe limitations for conventional drain fields, so establish site feasibility before buying¹³. Inside the Aquifer Protection Overlay Zone, installation or replacement requires Wyoming-licensed professional engineering, and new systems on lots under 35 acres require qualifying advanced treatment units⁶.

We could not confirm a private-parcel RV or tiny-home occupancy rule for unincorporated Albany County; ask Planning about the proposed use and district before moving onsite⁷. County campground standards require a campground conditional-use permit and at least 2 acres, but do not resolve occupancy of an RV on an ordinary private parcel^11,14. An accessory dwelling is allowed only in districts specified by the land-use table, limited to one per property, and prohibited in the Aquifer Protection Overlay Zone². Detached accessory dwellings are limited to 1,200 square feet or 75% of the principal dwelling, whichever is less; attached units are limited to 40% of the principal dwelling’s area². Applicable wastewater approval must precede the accessory-dwelling zoning certificate². Mobile-home parks require at least 2 acres and a special conditional-use permit; manufactured homes in a park need approved spaces with water and sewer connections^2,11.

1. Submit the zoning-certificate form, correct fee, ownership evidence, site plan, and applicable easements or approach licenses; wait for approval before construction⁹.

1. Submit the wastewater application, fee and design materials, obtain permission to construct, and leave the completed system uncovered and unused until inspection and approval³.

1. Apply through the Wyoming State Engineer's Office before drilling a water well⁵.

In unincorporated Albany County’s Urban Residential district, minimum lots depend on utilities: 1 acre with centralized water and onsite sewage, 15,000 square feet with onsite wells and centralized sewer, or 10,000 square feet with both centralized water and sewer¹¹. Urban Residential subdivisions require centralized water or sewer¹¹. Elsewhere, district-specific lot minimums still apply; there is no single residential acreage threshold to use countywide¹¹. Albany County precipitation averages about 15 inches annually, and severe drought occurs in about 13.9% of years; apply to the Wyoming State Engineer’s Office before drilling a well^5,13. The zoning application requires access information, but we could not confirm a standalone driveway-permit rule; ask Planning about the proposed approach^7,9.
