"Revised Owner Move-In Requirements. On July 11, 2017, the San Francisco Board of Supervisors passed new legislation amending the requirements for Owner Move-In (OMI) Evictions effective January 1, 2018 (see within).

Third-Party Lawsuits. New rules allow non-profit organizations to sue landlords when the organization believes a tenant has been illegally evicted, and if they prevail, to collect attorney’s fees from the landlord (see within).

Educator Protections Reinstated. In 2016, San Francisco adopted an ordinance barring “no-fault” evictions of families with children and educators during the school year. A law suit was filed in protest, and the trial court concluded state law preempted this ordinance. However, in 2018, the California Court of Appeal ruled that the City does have the legal authority to enforce this rule."
