I assume this is about eliminating car parking requirements.
What about changing the parking requirements to be vehicle agnostic? Require construction projects to have parking for X people, rather than X cars, and consider the requirement met if it's a mix of bicycle parking, cargo bicycle parking, and car parking.
Bicycle parking takes less space. So that'd be an incentive to deliver projets with more bicycle parking, and should help reduce housing cost.
California may not be bicycle-friendly, but it has to start somewhere to be. A colleague of mine used to commute to work in that area using an electric bicycle, it helps cover more distance than a classic bicycle.
