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

The address on a property in Eagle County 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.
