Check the address first. The city in a mailing address isn't always the city that governs the property, and boundaries change through annexation. Unincorporated areas follow County rules, where older buildings with 2+ units have a 1.919% cap.
How much notice to give
Under Civil Code 827, give at least 30 days' notice if the increase, together with any others in the past 12 months, is 10% or less. Above 10%, give 90 days.
