As California gets new rent-hike controls, the cost of renting in Los Angeles and Orange counties is rising at a pace not seen in 12 years, according to a slice of the local Consumer Price Index.

Local rents rose at a 5.6% annual rate in September vs. 4.9% a year earlier, says the U.S. Bureau of Labor Statistics. So far this year, this L.A.-O.C. rent index rose on average 5.5% compared with 4.9% in 2018 and 4.6% in 2015-2017. It’s a sharp contrast to the 2009-14 period when local rents rose on average 1.7% a year.

In the Inland Empire, a new CPI showed rents in Riverside and San Bernardino counties were up 4.7% in the 12 months ended in September.
