The Housing Accountability Act (HAA) — Government Code § 65589.5, part of California’s Planning and Zoning Law — is one of the most consequential and least-understood housing statutes in the state. Its central move is to narrow a local government’s discretion to reject housing.
What the HAA actually requires
The HAA prohibits a local agency from disapproving — or conditioning approval in a way that makes infeasible — a housing development for very-low, low-, or moderate-income households (or an emergency shelter) unless it makes specific written findings, supported by a preponderance of the evidence in the record, that the project would cause a defined health or safety harm and there’s no way to mitigate it.
In practice, that reverses the intuition many people have about local control. When a project complies with a jurisdiction’s objective standards, the burden sits with the city to justify a denial with evidence — not with the applicant to earn a discretionary yes. “We don’t think it fits the neighborhood” is not, by itself, a lawful basis to deny a compliant project under the HAA.
The 'builder's remedy'
The HAA also contains a provision (§ 65589.5(d)(5)) known as the builder’s remedy. When a jurisdiction’s housing element — the state-required part of its general plan that plans for its share of regional housing need — is out of compliance, the builder’s remedy sharply limits the city’s ability to reject a qualifying affordable or mixed-income project even if it doesn’t match current zoning or the general plan. It is a strong incentive for jurisdictions to keep their housing elements certified — and a live issue in California cities that have fallen behind.
SB 330: freezing the rules and speeding the clock
The HAA is reinforced by the Housing Crisis Act of 2019 (SB 330), which amended § 65589.5 and added tools of its own. Among the most important: a preliminary application that, once submitted, largely vests the fees and standards that apply to the project — so a city can’t move the goalposts mid-review — along with limits on how many hearings a compliant project can be subjected to and restrictions on down-zoning.
The HAA is complex, fact-specific, and heavily litigated — this is an orientation, not a roadmap for a particular project. But the through line is worth holding onto: whether a project complies with a jurisdiction’s objective standards is the pivotal question, and answering it accurately — against the actual code, for the actual parcel — is where good planning technology earns its keep.
