California just turned the housing and zoning game upside down, with state-level rules now threading through some of its most local decisions. With the passage of SB 79, the state is mandating higher-density housing near transit hubs, and yes, local governments are bristling.

For years, housing advocates in California have argued that local zoning and resistance are major factors in the state’s affordability crisis. With SB 79, the state legislature said: enough. The bill enables 4- to 9-story multifamily buildings within a half-mile of major transit stations in designated “urban transit counties.” The idea: build where infrastructure already exists, reduce car dependence, open up housing supply.

But here’s where the tension kicks in. The law puts significant limits on local discretion. Some cities, especially in North County San Diego and coastal zones, warn that their planning, design standards and neighborhood contexts are being overridden. In areas where transit service is less robust, or local neighborhoods have strong preservation or open-space priorities, officials are asking: “Is density being required at any cost?”

From a planning perspective this is huge. It asks cities to shift from “how to slow development” to “where and how to allow faster development.” For practitioners, the stakes are: How will zoning codes, permit processes and utility/infrastructure capacity adapt? Will communities see affordable units or simply market-rate towers near transit? Will rail corridors see meaningful housing gains or token density?

And for neighborhoods: Yes, more housing near transit is often good. But if new buildings disproportionately favor high-end units, or if local build-out overwhelms infrastructure (parking, schools, open space), then the policy could deliver supply without equity. Some critics say the real victory will be producing housing that working-income families can afford, not just units stacked near trains.

What to watch next:

In short: SB 79 isn’t just another reform. It is a shift in power, from local vetoes to state-mandated access. The question now isn’t can we build near transit? but will we build well, and build for everyone?
