Boulder County can landmark a historic home, which adds review

Outside the cities, in unincorporated Boulder County, an old building can carry a special status that shapes what its owner may do to it.

Boulder County runs a historic preservation program through its land use department. A structure, site, or district can be designated as a county historic landmark by the County Commissioners because of its historic importance. A Historic Preservation Advisory Board supports the program, and there is a formal process to apply for designation. The landmarks range widely: old homesteads and cabins, schoolhouses and churches, barns, mining structures, and remnants of former mountain towns.

Why this matters to a buyer or owner: a landmark designation usually comes with review of changes, especially to the exterior or to the site, so the historic character is kept. That can be a benefit, since it protects the place and the surroundings, but it also means some projects need an extra step of county approval rather than just a routine permit.

If a property you are considering is old, or sits among other historic buildings, it is worth asking whether it is a designated county landmark or in a historic area. Boulder County’s historic preservation pages list designated sites and explain the designation process, and that is the right place to confirm a specific parcel’s status.
