> There is a building going up in Oakland right now where Factory_OS put out a press release that they had built it in ten days. But they spent 7 years getting approvals, 18 months in site prep,

I'm currently gut remodeling a small house in Oakland. Permitting and regulations are a whopping 3% of the cost.

The land (the existing property) is 50%, and 40% is building costs.

Land costs (addressed via incremental upzoning) and build costs (addressed with more efficient building technology) are the 2 biggest things to address to make housing affordable, not the cost of permits.
