Mountain View FAQ
Can the Heritage Commission stop my demolition entirely?
Not permanently. The commission can impose up to a 180-day stay to allow buyer search, relocation, or design alternatives. If those efforts fail, the Board of Supervisors can make findings of override and let demolition proceed.
Does CEQA apply if my house is on the Heritage Inventory but not formally designated?
Yes. Inventory listing creates a CEQA presumption that the property is a historical resource, requiring an initial study before any demolition or substantial-alteration permit is issued by the county.
San Jose FAQ
Can I demolish a deteriorated historic building if it is unsafe?
Imminent-hazard demolitions follow Building Division emergency procedures, but the city investigates whether owner neglect caused the deterioration. Demolition by neglect can still trigger penalties and a five-year permit hold.
Does CEQA apply if my property isn't formally landmarked?
Yes, sometimes. Properties identified in the Historic Resources Inventory or meeting California Register criteria are still historic resources under CEQA Section 15064.5, even without formal city landmark designation.
