Proposals like these, while admirable, usually miss the mark and have little to no impact on housing availability because they fail to accept that housing development isn't just about zoning.
Impact fees, planning regs (traffic, parking, etc), planning delays, NIMBY fights, labor costs...these are all inputs into the question of whether a multifamily development makes economic sense for a developer.
There is a formula under which you can build market-rate and/or affordable housing (sometimes the same) and when that formula checks out, you see lots of development.
All of that has to work out to a cost per door and that cost has to be recouped in rents that pay for opex and debt. The fourplex in the article would cost $562,500/door. A very basic calc of the necessary rents would be $4,950.
California, particularly San Francisco, has pressures at every step of that formula. So if the Bay Area wants more housing, it has to be willing to look at the problem holistically.
- What role do planning review delays play in increasing the costs and perceived risk of acquiring a parcel and going through the process?
- What % of potential building sites are classified as historical properties?
- What are the parking, traffic impact and roadway requirements that multifamily traffic counts will have to mitigate/build for?
- What power do unions have to dictate building programs?
- Who can object to proposals?
I'm not suggesting that everything has to be Texas-style free markets, but to solve the problem one has to be willing to admit that it may require something a bit more comprehensive that simply changing zoning.
