Certifying Your Local Government


The CLG Program provides a community a process to identify, preserve and promote the historic places that tell their story and celebrate their identity as a unique and exciting place to live and visit. The program allows each community to decide what’s important to you and how to maintain and share what you find special.

Specific economic benefits include access to the CLG Grant Program and eligibility for State Historic Preservation Tax Credits.

A full list of benefits is available through the CLG Program Flyer or the CLG Handbook.


The CLG Program is a Federal Partnership with the State and Local Government with base requirements:

  • Enforce legislation for the designation and protection of historic properties.
  • Establish and maintain a qualified historic preservation commission.

  • Provide for public participation in the local historic preservation program.

A full list of responsibilities is available through the CLG Program Flyer or the CLG Handbook.

Interested counties and municipalities should submit a certification packet to History Colorado. Drafts of any of the required items can be submitted to History Colorado for review. Submission of a draft ordinance before completing the entire packet is recommended. History Colorado has 30 days to review the application. Once approved by History Colorado, the certification packet is forwarded to the National Park Service (NPS) for final review and official certification. NPS has 45 days to review the certification packet.
