Zone History Letter
A Zone History Letter confirms past and current zoning and land use regulations that govern a specific property within the City of San Diego’s jurisdiction and outlines redevelopment rights if zoning and land use regulations change.
Maintenance, repair, alteration, or reconstruction of a previously conforming structure, or a change in use, is subject to the requirements of San Diego Municipal Code (SDMC) §127.0101.
A Zone History will apply this code section when outlining redevelopment rights for previously conforming uses or structures.
Previous entitlements may be identified as part of the Zone History research (a complete listing of all entitlements and other restrictions can be obtained through a Title Company as part of a Title Report. Other local and state agencies may have jurisdiction over the property (e.g., Civic San Diego, Port of San Diego). Please refer to the Zoning and Parcel Information Portal (ZAPP) to confirm the jurisdiction.
