This metric counts the total number of commercial vacancy tax filings and specifically tracks properties reported as vacant. The Commercial Vacancy Tax requires owners of ground-floor commercial spaces in certain commercial districts to register and pay a tax if the space has been vacant for more than 182 days in a calendar year.
This data comes from Taxable Commercial Spaces, a public dataset maintained by San Francisco on the city's open data portal.
