OAKLAND (KPIX) — Oakland’s mayor is calling out Cupertino for not pulling its weight to deal with the housing crisis.

Oakland mayor Libby Schaaf tweeted:

“Last year the new Apple headquarters opened in Cupertino with space for 12,000 employees. Meanwhile, the City of Cupertino issued permits to build just 27 homes in 2017.”

On Wednesday night, Cupertino’s city council approved a plan for a major development at the old Vallco Mall, with nearly 3,000 housing units — many of them affordable.

But it’s a project that has been plagued by delays and heavy opposition from critics who say it will lead to traffic and overcrowding.

KPIX reached out to the city of Cupertino for a response to Mayor Schaaf’s tweet but have not yet heard back.
