Larimer County building permits mainly mean unincorporated property

Before any permit question, there is a quieter question hiding underneath it: who actually has authority over this address? Get that wrong and you can pull the right permit from the wrong office, and discover it only after the work fails inspection.

The county Building Division covers permits, plan review, inspections, and code enforcement for the unincorporated parts of Larimer County. For rural land, foothills parcels, and homes tucked into the canyons west of the cities, the county is almost always where the process begins.

Step inside the limits of Fort Collins, Loveland, or Estes Park, though, and the town or city runs its own building program with its own rules and reviewers. A mailing address does not settle which one applies; plenty of homes carry a city name in their address while sitting on county land.

So the first move with a remodel, garage, addition, deck, or repair is to pin down whether the parcel is unincorporated, not where the mail goes. Once you know it sits with the county, the Building Division page is the door to permits, inspections, codes, and the online portal.
