Outside the towns, Eagle County's rules are the ones that apply

In Eagle County, the address on a property does not always tell you who makes the rules. The county has incorporated towns like Vail, Avon, Eagle, and Gypsum, each with its own town government. But a large share of the county is unincorporated, and some well-known communities, such as Edwards, are not towns at all. There, the county is the local government.

This trips up buyers who assume a town hall is in charge. Unincorporated does not mean unregulated. Eagle County runs its own land use regulations, planning review, and building permits, and septic systems on a property without sewer service fall under county and state health rules. If you want to add a structure, run a short-term rental, or build, the county is who you deal with, not a town.

It is worth checking early, because the rules and the permitting path can differ depending on whether your parcel is inside a town or in the unincorporated county. Two nearby lots can answer to different governments.

To find out which rules apply to a specific Eagle County parcel, start with the county’s Community Development department for planning and building, and confirm the jurisdiction before you plan a project.
