SB 79 Implementation: The Gap Between Intent and Reality

SB 79 was designed to do something simple but essential: make it easier to build homes near transit. As implementation unfolds across California, a clear pattern is emerging — many cities are quietly working to limit, delay, or work around its real-world impact.

HAC has been tracking this closely, and in recent weeks the stakes have gotten higher.

The Regional Picture

In the Bay Area, Oakland and Mountain View provided early warning signs. Oakland's Planning Commission pushed back on blanket exclusions in high-resource transit corridors, with advocates successfully preserving SB 79's application near Rockridge and Ashby BART. Mountain View proposed relying heavily on discretionary Bonus FAR processes that could undermine the law's objective framework. Both cases showed that strong public engagement shapes outcomes, and that cities will test the boundaries of the law if no one is watching.

Southern California: SCAG Gets It Wrong

The stakes jumped significantly this month when the Southern California Association of Governments released preliminary draft maps for SB 79 implementation in LA County, and the methodology is flawed in ways that could lock in harm for years.

SCAG's maps omit planned transit stops that both the statute and HCD say must be included. They also count commuter rail frequency in a way that conflicts with HCD's own guidance, effectively erasing some of the region's busiest rail hubs from eligibility. HAC joined local advocates at SCAG's June 4th committee meeting to oppose these interpretations. Despite that opposition, the committee approved the maps. They now head to the SCAG Regional Council for a final vote on July 2nd.

Getting the maps right isn't a technicality. Inaccurate maps mean fewer by-right sites, invite legal challenges, and increase costs for cities and developers alike. HAC has filed a formal complaint with HCD and will be meeting with state staff to push MPOs and local jurisdictions to stay on the right side of the law. We'll continue pressing SCAG to fix the methodology before the maps are finalized.

Palo Alto: Delay by Emergency Ordinance

The most direct challenge to SB 79's intent right now is in Palo Alto, where the City Council is moving to adopt ordinances delaying the law's implementation and has signaled it may use the emergency ordinance process to do it.

HAC sent a letter to the Council this week urging it not to proceed. We raised two concerns:

The public doesn't have enough information to evaluate what's being proposed. The staff report doesn't tell the public how many historic resources actually fall within SB 79's eligibility areas, or what current allowable densities look like across those sites. That second point matters a great deal: without it, residents can't assess what it would mean in practice for an ordinance to cap development at just 50% of SB 79's minimum densities.

Emergency ordinances are the wrong vehicle. Under California law, emergency land use ordinances exist to protect public safety, health, and welfare — extraordinary procedural tools that come at the cost of the public's standard review and comment opportunity. New housing near transit doesn't meet that bar. Palo Alto cannot credibly characterize new housing as a public safety emergency. If the Council wants to delay SB 79, it should do so through the normal legislative process.

Palo Alto is a major employment center well-served by Caltrain and key bus corridors. It has both the opportunity and the obligation to add housing near transit. SB 79 offers exactly the kind of objective, predictable framework that can make that happen, and the City's own Housing Element says as much.

Why This Matters

SB 79 is one of the most important housing tools California has enacted in years. But a law is only as good as its implementation. Across the state, cities are testing what they can get away with: overly broad exclusions, alternative plans that delay action by years, and theoretical capacity that can't actually be built.

HAC's role is to hold that line: supporting the law's intent, pushing back on workarounds, and making the case that real implementation is both legally required and urgently needed. We'll keep doing that as this unfolds, in Palo Alto, at SCAG, and in every other city.
