Los Angeles Historic Preservation Overlay Zone

The Historic Preservation Overlay Zone of the City of Los Angeles in California has been hailed by historic preservation advocates for its pioneering program, which designates not just buildings but entire neighborhoods or districts as worthy of historic preservation.

Most of these districts are areas dominated by Victorian and Craftsman single-family houses, but some are predominantly Mission Revival or Spanish Colonial Revival, and one (the Gregory Ain Mar Vista Tract) is a mid-century modern area.
