California Governor Signs Housing Reform Package with Factory-Built Housing Standards

Governor Newsom signed major housing legislation on September 29, 2026, that cuts down on the number of reviews projects must go through and establishes new standards for factory-built housing. The package is part of California's broader push to increase housing supply and address affordability.

Santa Monica Upzones 89 Single-Family Parcels Near Transit to Sidestep State Law

Santa Monica City Council voted 5-1 on September 29, 2026, to increase density on 89 single-family parcels near the Expo/Bundy light-rail station. The move aims to shield the transit zone from California's SB 79 state housing law by proactively allowing higher density, preventing automatic upzoning that would otherwise occur.

Context & numbers

U.S. Housing Supply Debate: The AEI Housing Center estimates a nationwide shortage of approximately 6 million homes, though recent analysis notes the U.S. faces a meaningful shortage primarily of affordable units rather than a universal supply crisis—especially in high-cost markets where development costs remain prohibitive.

French Construction Trajectory: At the current August pace (27,663 units started), France's annual construction start rate would reach approximately 331,956 units. Permit authorizations at 29,749 units monthly translate to roughly 356,988 annually, both figures reflective of ongoing constraints in the French building sector despite recent momentum gains.

California Legislative Output: Governor Newsom's September 29 housing package includes reforms expanding starter home rules (SB 1116) that limit setbacks and story caps for qualifying 10-home projects and establish factory-built housing standards within the broader housing reform framework signed into law.

On the radar

• Factory-Built Housing Scaling: Plant Prefab's expansion into multifamily and single-family developments, with new facilities capable of producing 800+ units annually, signals growing industry investment in modular construction to accelerate housing delivery timelines—a key mechanism cited in recent state legislation.

• State Voting on Zoning: Massachusetts voters are set to decide a ballot measure on single-family zoning reform, representing the first direct voter referendum on zoning policy—outcome could signal broader appetite for density-permitting changes across other states.

• Permit Recovery Timing: French construction data suggests permits may rebound in coming months given the 4.1% acceleration in starts; watch October-November permit releases to confirm whether the August 1.1% decline signals stabilization or renewed contraction.
