Why Two Staircases Killed the Family Apartment

Industry News: California SB 79 and the Case for a Living Project Record

California’s SB 79 requires qualifying cities to allow multifamily housing near major transit stops, and several lawsuits over how cities are applying it have already followed. With Trent’s take on why that uncertainty makes the project record as valuable as the code itself.

The life cycle of a single ordinance. Zoning law is a redline, not a snapshot, and a model trained on one snapshot cannot tell you which version governs today.

Because the records underneath were never built to be read by machines, and Brookings argues housing needs shared data infrastructure before AI can deliver on the promise.
