Dwelling Unit Removal - Merger, Conversion or Demolition Supplemental

The Housing Crisis Act of 2019 (HCA), adopted in Senate Bill 330 (SB 330), establishes a statewide “housing emergency” until January 1, 2030. During the housing emergency:

  • the Housing Crisis Act suspends certain restrictions on the development of new housing and expedites the permitting of housing;
  • the Housing Crisis Act  prohibits the demolition of housing. Dwelling unit merger and conversion procedures will not be impacted and continue to require the Planning Commission to grant a Conditional Use Authorization;
  • cities and localities in urban areas, such as San Francisco, are generally prohibited from rezoning or imposing new development standards that would reduce the capacity for housing or adopting new design standards that are not objective;
  • the loss of existing housing units (through demolition) is only permitted if the same number of units are created as part of the same development project.

Effective February 9, 2026, the Tenant Protections Ordinance codifies HCA housing replacement and tenant protection requirements through the addition of Section 317.2 to the Planning Code.

A Project Application must be completed and/or attached prior to submitting this Supplemental Application. See the Project Application for instructions.

Pursuant to Planning Code Section 317, the Planning Commission shall hear and make determinations regarding the loss of dwelling units including the loss of unauthorized dwelling units, with some codified exceptions.
