California· Answer
Is a California landlord required to justify a rent increase?
Short answer
Within the cap, California does not require justification: any increase up to 10% (or the lower of 5% plus CPI) is permitted with the proper notice. Above the cap, the increase is void unless the unit is exempt. Local rent-control ordinances may impose pass-through or hardship justification.

Honest limits
This is an informational answer based on Cal. Civ. Code 827(b) as of early 2026. It is not legal advice. Housing law changes year to year and local ordinances (especially in rent-controlled or rent-stabilized cities) can override or add to state law. For contested cases, consult a California-licensed attorney.
