In SF rent control only applies to buildings that are like 40-50+ years old. Yet people still complain as if it stops new housing. If you combine this with the idea that rent control raises prices for everyone else, you'd think people would be knocking down the doors to build: artificially high rents for decades.
Rent control absolutely causes a reduction in supply: there's a reason rent controlled buildings have apartments in poor condition that owners do not renovate (so a reduction in quality supplied) and many are held off market or converted to owner occupancy through condos and TICs (so a reduction in quantity supplied). Not to mention the units underused by long term tenants who maintain them as secondary residences.
