The Environmental Law That Became a Housing Veto

In 1971, a developer proposed 184 condominiums, a restaurant, and shops on 5.5 acres near Mammoth Lakes. The neighbors sued over snow removal and parking. That single lawsuit is why, more than fifty years later, an apartment building anywhere in California can still be dragged into years of litigation by anyone who simply doesn’t want it built.

A Distortion of the Law

The Legislature enacted the California Environmental Quality Act in 1970 to force the state to disclose the environmental cost of its own public works. It targeted government: the freeways, the dams, the concrete the state was pouring across the landscape while nobody counted the cost.

Then a court changed everything. On September 21, 1972, in Friends of Mammoth v. Board of Supervisors, the California Supreme Court ruled that CEQA covered private housing too, not just the state’s own projects. The court took a law written to watch the government and pointed it straight at people trying to build homes. It even warned everyone off reading the statute narrowly, calling that a “grudging, miserly reading.”

That single ruling armed every NIMBY in California. For fifty-three years, if you did not want the apartment next door, you filed a CEQA challenge and ran out the clock. The neighbors did not have to win. They just had to make building slow enough and expensive enough that the homes never happened. They blocked market-rate housing. They blocked affordable housing. They blocked homeless housing. They used an environmental law to keep working families out of their neighborhoods, and they got away with it for half a century.

Legislative Progress

On June 30, 2025, California started taking the tool back. Governor Newsom signed AB 130 and SB 131 and forced the Legislature’s hand: he made the entire $321 billion budget “inoperative and repealed” unless CEQA reform passed by midnight. Both chambers passed it that night.

AB 130 exempts infill housing outright on sites of 20 acres or less that already meet local zoning and density rules and sit on safe, non-historic land. It puts a hard 30-day clock on cities. SB 131 goes further: if a project misses the exemption by one condition, it now studies only that one thing instead of everything. It also clears child care centers, health clinics, food banks, farmworker housing, parks, wildfire prevention, and water systems. For the first time since 1972: follow the rules, and you get to build.

This works. In La Cañada Flintridge, the 600 Foothill project claimed the exemption three days after Newsom signed, after years trapped in court. In Studio City, an 814-unit project cleared the Planning Commission unanimously in about nine months. The developer’s attorney put it plainly: “The Housing Accountability Act is a game changer for us,” said Sheri Bonstelle — and AB 130’s exemption, stacked on top of it, sealed the deal. Nine months at that scale used to be impossible. Nobody rents an apartment that spent a decade as a lawsuit.

Finishing the Job

The Western Center on Law and Poverty, defending CEQA, admits fewer than 2% of projects ever face litigation and only 6% require a full environmental report. This is illuminating. If almost nobody gets sued, CEQA was never really protecting the environment. It was holding a threat over every builder in the state: give the neighbors what they want or get buried in court. You do not have to sue every project when suing 2% teaches the rest to fold. That is not environmental review, but a disingenuous way of blocking housing for working families.

Everyone defending CEQA should be honest about what they are defending. A veto that blocks homeless housing as often as it blocks a refinery was never protecting a community. It was locking people out of one.

This November, voters have the opportunity to finish the job themselves. Proposition 45, the Building an Affordable California Act, would amend CEQA to expedite environmental review for housing, transportation, water, health, and clean energy projects. It sets enforceable deadlines: agencies get 365 days to approve or deny a project, and if they miss it, applicants can force a public hearing and a decision within 60 days. It makes agencies review projects against objective, written standards instead of shifting goalposts while retaining a 45-day public comment period.

Repeal and reform CEQA. Keep exempting the housing. Pass Prop 45 this November. Stop handing anyone with a grievance and a lawyer the power to decide whether the next family gets to live here. A court created this weapon in 1972. It’s time to take it away.
