The largest distortion to the housing market in California is Prop 13, and its effect is statewide not just confined to SF. This is a large reason why escaping SF's rules by going to bordering/nearby cities doesn't result in significantly lower housing costs. More new supply is great, but doubt it would be enough to significantly offset the much larger effect of Prop 13.
