“In the mid-’90s, California was going through an affordable housing crisis. To encourage more housing development, two politicians, Democratic Sen. Jim Costa of Fresno and Republican Assemblyman Phil Hawkins of Bellflower, wanted to curb rent control.
They drafted the Costa-Hawkins Rental Housing Act, and in 1995 it passed by one vote.
Costa-Hawkins shaped rent control across the state in two big ways.
First, it allowed landlords to raise the rent to whatever they want after a tenant moves out of a rent-controlled apartment. This is called vacancy decontrol.”
