The San Francisco Board of Supervisors approved an ordinance amending the Planning and Building Codes. Key changes include requiring development applicants to disclose the presence of any Unauthorized Dwelling Units and mandating Planning Department investigation of such units upon application submittal. The ordinance also expands the Department of Building Inspection's compliance control program to address fraud and misrepresentation regarding Unauthorized Dwelling Units in permit applications, with potential penalties up to $250,000 for misrepresentation of material information. Furthermore, it requires the Planning Department to document properties subject to rent control ordinances and inspect properties prior to recommending approval of any loss of residential or unauthorized dwelling units. The ordinance also details regulatory agreement requirements for projects utilizing density bonuses or exceptions to density limits, subjecting new units to the San Francisco Residential Rent Stabilization and Arbitration Ordinance.
