The Covid-era additional requirement for an eviction notice in San Francisco was imposed by the Ordinance 18-22 in early 2022 and remained on the books since then, even though it was trimmed a bit later that year by the San Francisco Apartment Association winning against the application of the additional 10-days notice for an eviction for non-payment of rent. As of September 11, 2024, the entire ordinance now is seemingly on its way out, with SFAA winning its on its appeal.
Technically, the reversal is not "there" yet: the decision needs to take time to come back to the trial-level court for it to order the ordinance off the books, or it could be further appealed to the California Supreme Court. But the chances of its revival look deem and the it is therefore predictable that in, about the next 60 days or so, San Francisco landlord won't need to go through an additional route of 10-day notices anymore.
