Annexation Decisions in Laramie County

Annexation is the process by which a municipality extends its corporate boundaries to include previously unincorporated land. Once annexed, the land becomes subject to the municipality's zoning authority, building codes, tax jurisdiction, and public services (water, sewer, police, fire). ZoneWire tracks annexation activity across Laramie County, WY public meetings.

The Laramie County Planning and Development Department administers development and building permitting, inspections, and code enforcement within unincorporated Laramie County under the Laramie County Land Use Regulations (LCLUR). These regulations apply to all lands within the county except federal lands and any land within the incorporated limits of a city or town, so property inside Cheyenne and other municipalities is governed by that city's own zoning rather than the county's. The Planning and Development Department can be reached at (307) 633-4303 or planning@laramiecountywy.gov.

The Laramie County Planning Commission holds its public hearings at 3:30 p.m. on the second and fourth Thursday of each month, with the exception of the fourth Thursday in November. The Commission holds public hearings on applications for new subdivisions, zone changes, changes to the regulations, and special projects, and it makes recommendations based on the Laramie County Land Use Regulations and the community vision in the Laramie County Comprehensive Plan.

A zone change first goes to the Planning Commission for a public hearing and recommendation using the criteria in the Land Use Regulations, and then to the Board of County Commissioners for a public hearing where the commissioners may approve, deny, or table the request. Notice requirements include the applicant posting the property at least 30 days before the public hearing, the Planning office notifying adjacent property owners by certified mail at least 30 days prior, and publication of a public notice in the newspaper at least 30 days prior.

Laramie County operates under the Laramie County Land Use Regulations (LCLUR), which the Board of County Commissioners adopted on August 5, 2025, along with an amended unincorporated zone district map and an updated development fee schedule. This 2025 edition replaced the prior LCLUR (2022 edition, amended October 4, 2022). The regulations establish the county's zoning districts and the specific development standards that apply within each district.

In unincorporated Laramie County, an accessory structure larger than 200 square feet is required to obtain a building permit, while accessory structures less than 200 square feet that have neither electric nor plumbing service are exempt from building permits. Building permitting, inspections, and code enforcement are handled by the Laramie County Planning and Development Department; contact them at (307) 633-4303 to confirm whether a specific project requires a permit.
