This ordinance amends the San Francisco Planning Code and Building Code to enhance regulations related to Unauthorized Dwelling Units (UDUs) and rent-controlled properties. It mandates that applicants disclose the presence of any UDU in development applications and requires the Planning Department to investigate such units upon submission. The ordinance also obligates the Planning Department to document properties subject to regulatory agreements under the San Francisco Residential Rent Stabilization and Arbitration Ordinance and to inspect properties before recommending approval for the loss of any residential or unauthorized dwelling unit. Furthermore, it expands the Department of Building Inspection's (DBI) Expanded Compliance Control Program to address fraud, bribery, and misrepresentation concerning UDUs in permit applications, establishing penalties up to $250,000 for material misrepresentations regarding tenant history or UDUs. The definition of an Unauthorized Dwelling Unit is also amended to include a 10-year limit on its usage without a permit.
