After extensive renovations, Gov. Jerry Brown and his wife, Anne Gust Brown moved into the mansion in late 2015, becoming the first chief executive to live in the home since Ronald Reagan in 1967. The California Energy Commission will take up a proposal, Wednesday, May 9, 2018 , to require solar panels on new residential homes and low-rise apartment buildings up to three starting in 2020.
