Changes to Rules for Housing Projects and Lot Splits Near Historic Sites

This law changes when cities must quickly approve housing projects or split city lots by narrowing the types of historic sites that stop fast approval.

What This Bill Does

  • Requires local agencies to use a quick review process for new housing if it is not in specific contributing structures within historic districts, individually listed historical resources, or designated landmarks.
  • Allows cities and counties to create clear rules to protect the historical value of districts on the California Register of Historical Resources.
  • Changes the rule for splitting city lots so that fast approval happens unless the land is a historic landmark property included in state lists or designated by local ordinance.
  • Requires that any split lot project must not tear down or change specified existing structures.

Who It Names or Affects

  • Cities and counties responsible for approving housing projects and map changes
  • Developers proposing new housing in urban areas
