Property History Reports
The Museum Coordinator researches the histories of historic buildings in Louisville and creates reports to assist the Planning Department and Historic Preservation Commission. Reports are available through the City of Louisville Digital Records Repository. Please contact the Louisville Historical Museum if you would like to find out historical information about a particular property in Louisville not listed in the Digital Records Repository.
Historic Building Surveys
In an effort to maintain a library of historical and architectural information on Louisville, the City Planning Department has commissioned historic building surveys for a portion of Old Town. Surveys are listed by street address and may also include copies of Boulder County Assessor cards originating from the 1940s.
Please keep in mind that the buildings and sites may have undergone significant changes since these surveys were completed and owner information may no longer be current. Changes to the site may not be noted on the survey.

In 2010-11, the Louisville Historical Museum acquired scanned images of many property appraisal records originally created by the Boulder County Assessor’s Office. These cards are currently located at the Carnegie Branch Library for Local History in Boulder. The Museum now holds digital images of 1,291 assessor cards that relate to the Louisville area. They cover the Main Street commercial area and subdivisions such as Jefferson Place, Caledonia Place, Capitol Hill, Pleasant Hill, and others.
Louisville's County Assessor cards for 1948-1983 are available through the Museum's online collection. Use a keyword search or search for address in quote marks (e.g. "740 Front").
How to Read an Assessor Card
Assessor cards include information about the acreage and the building. The valuation of each property was assessed using checklists and information about condition.
