SEC. 2950. SHORT TITLE. This Article 29A shall be known as the “Empty Homes Tax Ordinance,” and the tax it imposes shall be known as the “Empty Homes Tax.” (Added by Proposition M, 11/8/2022, Eff. 12/23/2022, Oper. 1/1/2024) SEC. 2951. FINDINGS AND PURPOSE. (a) Residential vacancies are an ongoing concern in San Francisco. According to census data, there were tens of thousands of vacant residential units in San Francisco as of 2019. A report published in January 2022 by the Budget and Legislative Analyst found that the total number of vacant units in San Francisco increased by about 20% between 2015 and 2019, to 40,500 units in 2019. (b) According to the Budget and Legislative Analyst report, vacant units in 2019 were concentrated in the South of Market area, downtown, and in the Mission District; generally the same areas where new, large-scale housing construction has been concentrated. Such units are disproportionately in multiunit buildings. (c) The Empty Homes Tax is limited to buildings with more than two residential units because such buildings are more likely to include one or more units held vacant by choice and are more likely to include multiple vacancies. (d) Prolonged vacancy restricts the supply of available housing units and runs counter to the City’s housing objectives. Prolonged vacancies can also decrease economic activity in neighborhoods and lead to blight. (e) The Empty Homes Tax is intended to disincentivize prolonged vacancies, thereby increasing the number of housing units available for occupancy, while also raising funds for rent subsidies and affordable housing. (Added by Proposition M, 11/8/2022, Eff. 12/23/2022, Oper. 1/1/2024) SEC. 2952. DEFINITIONS.

For purposes of this Article, the following definitions shall apply: “Affiliate” means a person under common majority ownership or common control, whether that ownership or control is direct or indirect, with any other person, including but not limited to a person that majority owns or controls, or is majority owned or controlled by, any other person. “Building Permit Application Period” means the period following the date that an application for a building permit for repair, rehabilitation, or construction with respect to a Residential Unit is filed with the City through the date the Department of Building Inspection or its successor agency grants or denies that application, not to exceed one year. Notwithstanding the preceding sentence, if more than one building permit application is filed by or on behalf of one or more persons in the Owner’s Group for the same Residential Unit, the Building Permit Application Period shall mean only the applicable period following the date the first application is filed with the City by or on behalf of anyone in the Owner’s Group. “Construction Period” means the one-year period following the date that the City issues a building permit for repair, rehabilitation, or construction with respect to a Residential Unit, provided that if the City issues multiple building permits to or for the benefit of one or more persons in the Owner’s Group for the same Residential Unit, the Construction Period shall mean only the one-year period
