The statute does not use one statewide inflation number. It uses the April 12-month change in the Consumer Price Index for the metro area containing the unit, and California has four metro CPI series plus a statewide figure for everywhere else. Two adjacent counties in different metro areas can legitimately have different caps in the same year.
All five figures reset every August 1st, when the previous April's CPI takes effect. An increase served in July and one served in August can be governed by different caps.
