Vacancy Taxes: A Possible Taking?

Vacancy taxes are an increasingly popular solution to the paradoxical problem of high housing demand coupled with high vacancy. Cities across the country facing housing shortages have either implemented or are considering adopting vacancy taxes to encourage property owners to rent or sell their property. Soon after San Francisco adopted a vacancy tax with one of the broadest definitions of vacancy, property owners lobbed a constitutional challenge under the Takings Clause, taking advantage of a moment of doctrinal instability. This Comment seeks to make sense of how this and similar potential challenges would fare, given an expanding, property-protective takings doctrine, but a high constitutional tolerance for taxes. Using the San Francisco vacancy tax as a concrete example, this Comment evaluates possible arguments that the tax effects a regulatory or physical taking. It contends that even this stringent vacancy tax would not be a taking under either framework, and highlights elements of a different vacancy tax or regulation that may tip the scales of this analysis. It explores original understandings of land use (and nonuse) regulations to argue that fines levied on the nonproductive use of property are a background principle of property law that generally precludes the conclusion that vacancy taxes are takings.
