Summary
Placer County lets property owners nominate buildings, sites or districts to its Official Register of Cultural and Historic Resources. Once listed, no demolition permit can issue without 90 days' notice to the planning director, and the historical advisory board and board of supervisors review every application.
The alteration, reconstruction, demolition, or destruction in whole or part, of a designated cultural resource or a site in a designated historic district is prohibited unless written permission is granted by the planning director or designee pursuant to this section. The property owner of such structure, or an authorized agent, must give the planning director 90 days prior written notice that such act is planned for such structure.
