Proposition 45 Splits Bay Area Pro-Housing Groups Over CEQA Timelines and Sprawl

For nearly a decade, California's pro-housing movement has rallied around streamlining the California Environmental Quality Act (CEQA) to prevent lawsuits from stalling new residential construction. Yet with Proposition 45 on the Nov. 3 statewide ballot, the state's pro-housing organizations are split over whether the measure's sweeping timelines go too far beyond urban infill.

Backed by the California Chamber of Commerce, the Housing Action Coalition, and affordable housing developers, Proposition 45 would establish binding deadlines for environmental reviews and court challenges on projects classified as "essential" — a category covering housing, clean energy, water systems, roads, hospitals, schools, and broadband infrastructure.

However, the measure has divided Bay Area and statewide housing advocates:

• Supporting Prop. 45: Assemblymember Buffy Wicks (D-Oakland), the Housing Action Coalition (HAC), and affordable housing developer Eden Housing.
• Opposing Prop. 45: Eastbay for Everyone and the Greenbelt Alliance, alongside labor, environmental justice, and health coalitions and 19 members of the state Legislature.
• Neutral ("No Recommendation"): Flagship advocacy groups California YIMBY, YIMBY Action, SPUR, and Abundant Housing Los Angeles.

Strict Shot Clocks on Reviews and Lawsuits

Rather than exempting projects from environmental review outright, Proposition 45 imposes statutory deadlines across the permitting and litigation process for essential projects:

• Environmental Impact Reports (EIRs) must be completed within 365 business days.
• Public comment periods are capped at 45 days.
• Lawsuits challenging an approval must be filed within 30 days and fully resolved — including appeals — within 270 business days.

The measure also restricts the arguments and evidence that challengers can introduce in court and limits full environmental reviews to projects exceeding measurable thresholds under existing environmental laws. It does not alter local zoning and explicitly excludes the Delta tunnel, nuclear power, jails, and high-speed rail from its definition of essential projects.

The Debate Over AB 130, Infill, and Sprawl

The rift inside the pro-housing coalition centers on whether CEQA streamlining should remain focused on existing urban neighborhoods or extend to greenfield subdivisions and highway infrastructure at the metropolitan fringe.

"The central question here is how you feel about sprawl," California YIMBY policy manager Max Dubler wrote in the organization's non-endorsement analysis, pointing to the tradeoff between faster clean-energy permitting and making it easier to build "car-dependent sprawl housing and the freeways and water infrastructure necessary to serve that sprawl."

Jordan Grimes, legislative director at the Greenbelt Alliance, opposes Prop. 45 and argues that Assembly Bill 130 — authored by Wicks and signed into law last year — already solved CEQA delays for most urban infill housing. Since taking effect in July 2025, AB 130 has been used by developers to entitle 17,913 housing units, according to the state Office of Land Use and Climate Innovation.

"When you look at what's left to do on urban housing, there are absolutely still barriers," Grimes said. "CEQA just isn't one of them."

Supporters of Prop. 45 counter that AB 130 is limited to urban infill sites smaller than 20 acres, leaving out large-scale redevelopments such as the Hillsdale Mall, the former Vallco Mall, and Stonestown Galleria.

"I'm an 'all of the above' person when it comes to housing," Wicks said in explaining her support for Prop. 45. "I think we need housing of all different types, shapes, and sizes."

Linda Mandolini, president of Hayward-based affordable housing developer Eden Housing, noted that even infill projects remain vulnerable to multi-year court delays without litigation shot clocks. Mandolini pointed to Eden Housing's planned 130-unit affordable housing development on a former grocery store parking lot in downtown Livermore, where a 2021 CEQA lawsuit delayed the project for two years even though lower and appellate courts ruled the challengers' arguments "almost utterly without merit."

"Every year you lose in litigation is real money for real projects and another year that 130 families don't get to live in that housing," Mandolini said.

Dispute Over Broadband Language and Data Centers

In recent weeks, the No on Prop. 45 campaign — whose top funders include Wendy Schmidt — has also argued in political ads and a press release that the measure's inclusion of "broadband internet infrastructure" among essential projects could fast-track data centers. Matthew McKerley, an attorney at Shute, Mihaly & Weinberger, argued that Prop. 45 could undermine legislative safeguards on data centers.

The Yes on 45 campaign rejected that claim, citing a review issued last week by California's nonpartisan Office of Legislative Counsel confirming that data centers are not included in the definition of "broadband internet access service" under the California Government Code.
