Summary
Under Berkeley's Rent Stabilization Ordinance, any rent increase tied to the annual general adjustment or an individual rent-ceiling petition takes effect only after the landlord gives the tenant at least 30 days' written notice and the notice period runs out.
An upward general adjustment in rent ceilings does not automatically provide for a rent increase. Allowable rent increases pursuant to a general upward adjustment shall become effective only after the landlord gives the tenant at least a 30 days written notice of such rent increase and the notice period expires.

Full Breakdown
76, the Rent Stabilization and Eviction for Just Cause Ordinance, ties permissible rent increases to a rent ceiling set by the Rent Stabilization Board. A allows an annual general adjustment each January 1 equal to 65% of the prior year's Bay Area CPI increase, floored at 0% and capped at 5%, published by the Board around October 31. G, where a landlord or tenant petitions the Board for an upward or downward adjustment based on factors like capital improvements, operating costs, or fair return on investment.
No general-adjustment increase takes effect at all if the landlord has failed to comply with a Board order, failed to bring the unit into compliance with the implied warranty of habitability, failed to make ordered repairs, or failed to register the unit by July 1; a landlord who registers late loses 10% of the eligible adjustment for every month of delay beyond October 1. The rent ceiling system traces back to a May 31, 1980 base rent, later modified for units that gained a Costa-Hawkins vacancy decontrol initial rent.
Violations & Fines
A rent increase imposed without the required 30-day written notice is not effective and the landlord cannot lawfully collect it; landlords who are out of compliance with a Board order, habitability requirements, or registration by the July 1 deadline forfeit that year's annual general adjustment entirely, with late registrants losing 10% of the adjustment per month of delay. Tenants and the Board can challenge noncompliant increases through the individual petition hearing process under Section 13.76.120, which can result in a downward adjustment of the rent ceiling.
