90-Day Notice Required for Rent Increases Exceeding 10% Per Year

Effective January 1, 2020, California Civil Code Section 827 was amended to require the service of a written 90-day notice (instead of a 60-day notice) if the rent increase, either by itself or combined with any other rent increase in the 12 months prior to the effective date of the increase, is more than 10%. The required notice period for an increase of 10% or less (combining all prior increases within the 12 month period before the increase goes into effect) remains 30-days. If a rent increase notice is served by mail, the required notice period must be extended by an additional five days (i.e. If the increase exceeds 10% of the tenant’s rent and is served by mail, it cannot be effective less than 95 days after the date of mailing).
