Building in sage-grouse habitat can mean an early talk with the county

In mapped Gunnison sage-grouse habitat, Gunnison County requires a pre-application conference for certain land-use projects and lets owners request one before building or septic permits.

Published June 10, 2026 - Last verified June 15, 2026

In much of Colorado, a building or septic plan starts with the county building or planning office. In parts of Gunnison County, there can be one more early step.

The Gunnison Basin holds important habitat for the Gunnison sage-grouse, and the county has built that into its development process. For certain land-use change projects — what the county classes as minor or major impact projects — in mapped sage-grouse habitat, a pre-application conference is required. For building permits and on-site wastewater (septic) systems in that habitat, the county lets owners request the same kind of early conference, though it is not required. Either way, review of a parcel wholly or partly within mapped habitat can bring in the county’s wildlife conservation coordinator and Colorado Parks and Wildlife, so habitat questions are raised early rather than after a design is set.

Why a buyer or builder should care: whether a parcel sits in mapped sage-grouse habitat is a basic thing to check before counting on a particular plan, since it can shape timing and design. It does not mean a project is blocked; it means the conversation starts sooner and may include wildlife staff.

This is durable structure, not the full procedure. Before assuming what applies to a specific parcel, confirm the current process with Gunnison County Community Development and Colorado Parks and Wildlife.
