As part of the CLG Program, federal grants are awarded annually to local governments to assist with historic preservation programs. The most recent California CLG grant recipients are posted to our CLG Grant Awards page. 
To learn more about the grant program, please visit our CLG Grant Program webpage.

What are the requirements to be a CLG?

  • Enforce appropriate state and local laws and regulations for the designation and protection of historic properties;
  • Establish an historic preservation review commission by local ordinance;
  • Maintain a system for the survey and inventory of historic properties;
  • Provide for public participation in the local preservation program; and
  • Satisfactorily perform responsibilities delegated to it by the state.


How can a local government get certified?

Any general purpose political subdivision with land-use authority is eligible to become a CLG. A local government may apply to become a CLG by submitting an application, signed by the chief elected official of the applying local government, to OHP. If the applicant meets the criteria, OHP will forward the application and recommend certification to the NPS who makes the final cerification decision. When the NPS is in agreement with OHP's recommendation, a certification agreement is signed by OHP and the local government, completing the certification process. It is the local government that is certified, not simply the preservation commission.

Why become a CLG?

What’s in it for the local jurisdiction? Why would you want to associate your local preservation program with state and federal programs? Would you be giving up autonomy?



CALCLG-L is maintained by the California State Office of Historic Preservation and is one of the ways we disseminate CLG program information and provide technical assistance to CLGs. It also serves as an open forum for the posting of questions by list members and discussion of issues of interest to CLGs.

This list is open to Office of Historic Preservation staff, local government CLG coordinators, planners, members of local historical review commissions or boards, and other local government employees or volunteers who have professional responsibilities or interests related to their Certified Local Government Program. Guest memberships are available to staff members of cities who are considering or in the process of becoming CLGS.
