San Francisco opened a 145-unit affordable housing development in 19 months at around $525,000 per unit -- well below the Bay Area norm for comparable projects. The project used prefabricated components built off-site, combined with a design-build structure that kept decisions fast and scope locked.
The lesson: moving work off-site and defining the handoffs before construction starts is what compresses schedule. California's affordable housing funding programs reward schedule certainty -- the developers who hit LIHTC and AHSC timing windows are the ones who close their scope early.
1633 Valencia Street in San Francisco is a proof point. It shows what happens when coordination is treated as a design decision, not an afterthought.
