How to Handle a Rent Increase: Your Rights and Options

Rent increases are not automatically valid just because the landlord sends a notice. California law imposes specific requirements on the timing, amount, and content of rent increase notices — and tenants in covered units have additional protections.

Notice Requirements

For a rent increase of 10% or less, California law requires at least 30 days advance written notice. For increases over 10%, 90 days notice is required. Under AB 1482, the total increase in any 12-month period cannot exceed 5% + local CPI (capped at 10%). Rent increases that exceed these limits, don’t comply with notice requirements, or are served in a retaliatory context are challengeable.

The 90-day clock matters. A tenant who receives a large rent increase notice and responds to it within the 90-day retaliation window with documented prior protected activity (like a repair complaint) has a retaliation argument. Tenants who calendar the dates of their complaints and compare them to the date of any adverse landlord action are building the timeline they need.
