A History of Preservation in Longmont


In 1971 the City of Longmont established a Landmark Designation Commission, now known as the Historic Preservation Commission, to designate structures of historical and architectural importance which provide significant physical linkages to our community's past.

Since 1971, over 120 structures have been designated as local landmarks. In addition, nine of Longmont's local landmarks and two residential areas have been recognized as National Register Historic Districts. The City's commitment to a program of historic preservation and recognition has provided Longmont citizens with a deeper understanding of their community's rich and significant architectural, historical and cultural heritage.

The city's Historic Preservation Planner is continually updating the inventory of Designated Landmarks in Longmont. If you do not see a property listed by Address or Architectural Style, it will be on the List of Historic Properties in Longmont.  As time permits, staff will then add that property to our historic pages with a description and photograph.   

How are Properties Selected for Designation?

Longmont Landmarks

ldcplaqueLocal landmark designation provides for the recognition of sites, structures, objects and areas important to the history and character of Longmont, and protects them from exterior changes which might destroy or jeopardize their authenticity or distinctive features. A structure may be designated for preservation if it has historical, architectural or geographical importance to the community.

Property owners may apply for historic designation by the City through the submission of an application. Applications for Historic Designation are reviewed by the Historic Preservation Commission and approved by the City Council. Once a structure is designated as historic, no exterior building alterations are permitted unless a Certificate of Appropriateness has been granted by the Historic Preservation Commission. There are many types of financial incentives available for designated structures, including tax credits for qualified rehabilitation and refunds for certain building permit fees. 

Colorado State Register

The Colorado State Register of Historic Properties is a listing of the state's significant cultural resources worthy of preservation for the future education and enjoyment of Colorado's residents and visitors. Properties listed in the Colorado State Register include individual buildings, structures, objects, districts and historic and archaeological sites. The Colorado State Register program is administered by the Office of Archaeology and Historic Preservation within the Colorado Historical Society. The Society maintains an official list of all properties included in the Colorado State Register. Properties listed in the National Register of Historic Places are automatically placed in the Colorado State Register. They may also be nominated separately to the Colorado State Register without inclusion in the National Register. 

National Register of Historic Places

The National Register of Historic Places is the nation's official list of cultural resources worthy of preservation. Authorized under the National Historic Preservation Act of 1966, the National Register is part of a national program to coordinate and support public and private efforts to identify, evaluate, and protect our historic and archeological resources. Properties listed in the register include districts, sites, buildings, structures, and objects that are significant in American history, architecture, archeology, engineering, and culture. The National Register is administered by the National Park Service, which is part of the U.S. Department of the Interior.

The City of Longmont has two National Historic Districts. The Eastside Historic District is generally located between 4th and 8th Avenues between Kimbark and Atwood Streets. The Westside Historic District is located between 3rd and 5th Avenues between Terry and Grant Streets. The purpose of these districts is to recognize areas of the City that have special character and interest and exemplify outstanding elements of the City's heritage. Within these districts, a Certificate of Appropriateness is not required for any non-designated building alterations.
