National & State Registers

The Office of Archaeology & Historic Preservation (OAHP) assists property owners in listing Colorado’s most historically and architecturally significant buildings, structures, and sites in the National Register of Historic Places and the Colorado State Register of Historic Properties.


The National Park Service has proposed changes to the National Register of Historic Places regulations. The public commenting period closed on April 30, 2019. You can view History Colorado's official comments below, as well as a public information sheet that outlines where you can view the proposed changes, the public comments given, and examples of how the proposed changes would affect listing properties in the National Register. If and when the rule changes will be implemented are not yet known; current information will be posted when available.

Properties listed in the National or State Register may be eligible for investment tax credits for approved rehabilitation projects.  Listed properties are also eligible to compete for grants from Colorado's State Historical Fund.  These grants may be used for acquisition and development, education, and survey and planning projects.

Although OAHP strongly encourages the preservation of National and State Register properties, listing offers no automatic protection.  Private owners of National and State Register properties using private funds may alter or demolish these properties within existing local building regulations.  Projects involving federal or state agency actions or funding are reviewed by OAHP with the goal of preserving historic resources whenever possible.

OAHP staff is available to assist with the initial assessments of eligibility and to provide guidance in the completion of register nomination.
