Why the Newsom Duplex Ban in Wildfire Zones is Heading to Court

Why the Newsom Duplex Ban in Wildfire Zones is Heading to Court

California’s housing wars just took a sharp, litigious turn into the ash-strewn hills of Los Angeles. While Governor Gavin Newsom usually brands himself as the state’s "Housing Governor," a pro-housing advocacy group is now suing him for allegedly caving to wealthy homeowners and "influencers." The lawsuit, filed by YIMBY Law, targets an executive order that effectively hit the kill switch on Senate Bill 9 (SB 9) in neighborhoods recently scorched by the Palisades and Eaton fires.

The core of the fight is simple: Can the state’s duplex law—meant to solve a generational housing shortage—be tossed aside during a post-disaster recovery? Newsom says it's about fire safety and keeping evacuation routes clear. The plaintiffs say it's an illegal power grab fueled by NIMBY pressure.

The Executive Order That Sparked the Fire

In July 2025, Newsom signed Executive Order N-32-25. It gave local governments the green light to suspend SB 9 in "Very High Fire Hazard Severity Zones" within the burn areas of the Palisades and Eaton fires. For the uninitiated, SB 9 is the landmark 2021 law that lets homeowners split their lots or build duplexes on land previously restricted to single-family homes.

Almost immediately after the governor’s order, Los Angeles Mayor Karen Bass and officials in cities like Pasadena and Malibu jumped at the chance. They froze SB 9 applications, arguing that adding more "density" would turn narrow canyon roads into death traps during the next evacuation.

But here’s where the "why" gets messy. The lawsuit alleges that this wasn't some data-driven safety pivot. Instead, it claims the administration buckled under a loud campaign from affluent residents—including, notably, former reality TV star Spencer Pratt—who argued that duplexes would ruin the "character" of the Palisades.

Why Housing Advocates are Suing

YIMBY Law isn't just annoyed; they’re claiming the governor broke the law. The lawsuit, Yes In My Backyard et al. v. Newsom et al., argues that the California Emergency Services Act doesn't give the governor a blank check to rewrite housing policy.

  • The Emergency is Over: The fires were out by early 2025. The lawsuit argues that emergency powers are for active disasters, not for preemptively banning housing based on "speculative future crises."
  • Separation of Powers: The state legislature already debated fire risks when they passed SB 9. They included specific safety carve-outs. By issuing a new ban, the governor is essentially overstepping the legislative branch to appease a specific zip code.
  • Financial Ruin for Survivors: This is the most "human" part of the case. Many fire victims were underinsured. They can't afford to rebuild a $2 million mansion. Their only path to staying in their community is splitting their lot or building a rental unit to offset the massive construction costs. By banning SB 9, the state is effectively pricing them out of their own land.

Safety vs. Scapegoating

The safety argument sounds logical on the surface: more homes equals more cars, which equals slower evacuations. But the plaintiffs point out a glaring inconsistency. While the state is banning SB 9 duplexes, it’s not banning Accessory Dwelling Units (ADUs) or massive single-family mansions.

A 6,000-square-foot home with a guest house and a pool is perfectly fine, but a modest duplex is a "hazard"? That’s the logic the court is being asked to pick apart.

State law already allows a local building official to deny an SB 9 project if they can prove—with actual evidence—that it poses a specific, unmitigable risk to public safety. The lawsuit argues that this existing "safety valve" makes the governor’s blanket suspension totally unnecessary. If a specific canyon road is truly too narrow, the city can already block the project. They don't need an executive order to do it.

The Wealth Gap in Housing Policy

There’s no avoiding the optics here. The Pacific Palisades and Malibu are some of the wealthiest enclaves in the country. Critics of the ban argue that if this were a working-class neighborhood in the Inland Empire, the state wouldn't be suspending housing laws to "protect" the residents' views or "character."

By siding with the Palisades residents, Newsom has created a bizarre situation where he’s fighting his own pro-housing allies. It’s a classic California paradox: everyone wants more housing until it’s happening next door to a TikToker with a million followers.

What Happens Next

The legal team behind the suit, led by attorneys Ryan J. Patterson and Brian J. O’Neill, is seeking a court order to force Los Angeles and other cities to start processing SB 9 applications again. They want a judge to declare Newsom’s order "unlawful, unconstitutional, and void."

If the court sides with the housing groups, it’ll be a massive blow to "local flexibility" in fire zones. It would reinforce the idea that state housing laws aren't suggestions that can be turned off when things get politically heated.

If you’re a homeowner in a fire zone looking to rebuild, your next move is to watch the L.A. Superior Court docket for case number 25STCP04761. In the meantime, you should still look into ADU permits, which are generally not affected by this specific SB 9 suspension. If you were planning an SB 9 lot split, you might want to hold off on expensive architectural plans until the court weighs in on whether Newsom’s "firm lines" are actually legal.
