This is California Boom Loop Top Five Today, for Monday, April 20, 2026. Bringing you the most important stories about Pro-growth policy, housing, transit, and economic development in California.
First up, from The Emeryville Tattler, Brian Donahue: The Emeryville Tattler: Onni Project
This is a messy one. Emeryville’s planning director says Onni has withdrawn its application for a 54-story, 650-foot residential tower on Christie Avenue after refusing to pay project fees. The Tattler reports the 638-unit rental tower was already running into a wall of neighborhood opposition and new family-housing rules, but an anonymous City Hall employee says the real death blow was labor: Onni had poor relationships with Bay Area unions and wouldn’t work with them on the project.
the death knell for the controversial project ultimately came as a result of Onni’s poor relations among local Bay Area labor unions and their unwillingness to work with them on this project
My take: when a 638-unit apartment tower dies in a housing-starved region, everybody loses — but if developers want political cover for scale, they cannot treat labor like an afterthought and expect cities to save them.
And that gets us to a very different kind of growth story: smaller, steadier, and probably more durable.
From Bay Area Telegraph, Thomas Smith: Lafayette Just Landed $3.7 Million for a Major Downtown Trail
Lafayette has secured $3.737 million through the state’s 2026 State Transportation Improvement Program for the Downtown Lafayette Aqueduct Pathway. This segment will connect Dolores Drive to the Lafayette BART station, filling a key gap in a long-planned separated walking and biking route through downtown. The path runs in an existing utility corridor, roughly parallel to Mt. Diablo Boulevard, BART, and Highway 24, and the idea is simple: let people get to downtown and regional transit without getting shoved onto dangerous roads.
a fully separated walking and biking trail designed to give residents a safer, car-free way to get through downtown and reach BART
My take: this is exactly the kind of boring, high-value project California underbuilds — not flashy, not ideological, just a direct connection to transit that makes one-car or no-car life actually possible.
Now from one missing link in a trail network to the legal maze behind what gets built at all.
From Only Plans, Clifton Harness: Santa Clarita, CA Zoning
This is less a news article than a field guide to why housing reform in California keeps colliding with local code. Harness lays out Santa Clarita’s zoning as a classic Euclidean system with layer upon layer of overlays and specific plans. Residential zones are tiered from UR1 through UR5, but the naming doesn’t translate cleanly to actual development potential. There are more than 15 overlay types, and large swaths of the city sit in very high fire hazard severity zones, which matters because those areas trigger stricter building rules and can exclude parcels from SB 9 lot-split eligibility.
Overlay-heavy zoning: 15+ overlay types identified
The big point here is that the codebook itself is a barrier. Even where California says “yes” in theory, local zoning, overlays, specific plans, and hazard maps can turn that yes into a procedural swamp.
My take: if housing law requires a decoder ring, a wildfire atlas, and a land-use lawyer before anyone can add homes, the state does not have a housing market — it has a compliance obstacle course.
And while Santa Clarita shows the complexity problem, West Hollywood is showing what a workable deal can look like on an actual corner lot.
From The Pride LA: West Hollywood Project Trades Density for Low-Income Units at Key Corner
Construction has topped out at 8500 Santa Monica Boulevard, at Santa Monica and La Cienega, right on the West Hollywood-Los Angeles border. The six-story mixed-use project will deliver 30 apartments above 3,800 square feet of retail, with 33 subterranean parking spaces. The project uses density bonus incentives to go beyond standard zoning, and in return five units are set aside as affordable for low- and very low-income households.
As part of this agreement with the City of West Hollywood, five of the units are designated as affordable housing for low- and very low-income households.
This is not a giant building. But it’s a real infill project on a major corridor, next to jobs, transit, and existing urban fabric. California needs a lot more of these.
My take: density bonus is one of the state’s few housing tools that consistently turns policy into lumber, drywall, and keys — and cities that still fight it are choosing scarcity over inclusion.
And finally, the market backdrop hanging over all of this.
From GlobeSt., author not listed: Apartment Market Stalls as Supply Drops to 2016 Levels and Vacancy Holds Steady
The headline tells the story: apartment supply has dropped back to 2016 levels while vacancy is holding steady. That combination suggests a market that isn’t crashing, but isn’t really loosening either. Fewer new units are arriving, but there also isn’t enough excess vacancy to produce broad relief. In California terms, that means a lot of local officials may falsely read “stable vacancy” as permission to slow-walk new housing, when in reality a weak pipeline now is tomorrow’s rent pressure.
Apartment Market Stalls as Supply Drops to 2016 Levels and Vacancy Holds Steady
My take: steady vacancy with falling supply is not good news — it’s the calm before the next affordability squeeze, and every city using today’s softness to justify less building is setting renters up for the next spike.
A couple of reactions worth noting today. On Reddit, one Bay Area discussion about the AI boom and inequality struck a nerve, with users warning that the region could become even harsher if tech wealth accelerates faster than housing and transit capacity. One poster put it bluntly:
The Bay Area is going to get brutal if the AI boom is even half real.
That’s interesting because it links macroeconomic upside to the same local bottlenecks we talked about today: if you don’t build homes and mobility ahead of demand, growth turns into exclusion.
And there was also a smaller but very relatable Bay Area thread on ADU construction, with a homeowner saying,
the deeper we get into it, the more overwhelming it feels.
That matters because California loves to point to ADUs as an answer, but if ordinary households experience the process as confusing, expensive, and risky, then the policy success is still leaving a lot of production on the table.
