California SB 681 strengthens Housing Accountability Act and expands builder’s remedy

Tightens local authority to block affordable housing, clarifies density rules for builder’s‑remedy projects, and creates stronger court enforcement and financial penalties.

The Brief

SB 681 amends California’s Housing Accountability Act to make it harder for local governments to disapprove or downzone housing projects that provide very low-, low-, or moderate‑income units or emergency shelters. The bill updates definitions, clarifies when local rules can be applied to an approved project, and reshapes the builder’s‑remedy pathway for projects sited where a jurisdiction lacks a compliant housing element.

The measure also strengthens enforcement: it expands who may sue, alters evidentiary burdens in litigation, and creates stronger judicial remedies to compel approvals and to impose financial sanctions on noncompliant localities. Planning departments, affordable‑housing developers, and municipal counsel should expect shifts in approval practice, litigation risk, and compliance requirements if the bill becomes law.

At a Glance

What It Does

Amends the standards local agencies must meet to disapprove or condition approvals of housing for lower‑income households and emergency shelters; defines a new, clearer builder’s‑remedy framework for density and allowable standards; and limits the ability of localities to apply new ordinances to projects after a preliminary application is filed.

Who It Affects

Local governments and planning departments that review housing projects, affordable and mixed‑income housing developers, housing advocacy organizations and their counsel, and legal practitioners who litigate land‑use disputes under the Housing Accountability Act.

Why It Matters

The bill shifts more of the evidentiary burden and legal risk onto local agencies, creates predictable density calculations for builder’s‑remedy projects, and raises the stakes of denial through court‑ordered approvals and monetary fines—changes that can accelerate or change how housing projects are proposed and reviewed.

What This Bill Actually Does

SB 681 revises the Housing Accountability Act to narrow the permissible grounds a local agency may rely on to deny or condition affordable housing and emergency shelter projects. A local agency will face tighter scrutiny when it rejects or adds conditions that materially reduce a project’s viability; the statute focuses decision‑making on objective, written criteria and on whether there is an identifiable, quantifiable public‑health or safety impact that cannot be mitigated without rendering the project unaffordable or infeasible.

The bill codifies and clarifies the “builder’s remedy” route for developments on sites in jurisdictions without a housing element in substantial compliance. It sets out how to calculate allowable density for those projects, ties eligibility to specific site and density tests, and preserves applicants’ access to density bonuses and other concessions.

Importantly, builder’s‑remedy projects cannot be forced through general plan or zoning amendments, and localities cannot impose new, project‑specific requirements simply because the project used the builder’s‑remedy pathway.SB 681 also sharpens procedural protections for applicants. It defines “deemed complete” and “objective” standards, requires prompt written explanation from local agencies when they consider a project inconsistent with applicable rules (with different timeframes depending on project size), and provides a process for applicants to notify a local agency that a pattern of conduct effectively disapproves a project.

Where local governments persist in obstruction, the statute expands judicial remedies: courts can compel local action, fashion approvals, and direct monetary consequences tied to the project’s unit count.The bill contains transitional and temporal rules as well. It gives certain developers of projects deemed complete before a January 1, 2025 cutoff choices about which rules to follow, contains time limits and exceptions for when post‑application ordinances may be applied to a project, and includes several CEQA‑related provisions that are expressly time‑limited.

Together these changes reshape both the substantive and procedural landscape for affordable housing approvals in California.

The Five Things You Need to Know

1

A court may impose a minimum fine of $10,000 per housing unit for a local agency that violates the statute; fines must be deposited into a local housing trust fund (or Building Homes and Jobs Trust Fund) and spent on newly constructed housing for extremely low, very low, or low‑income households.

2

Builder’s‑remedy allowable density is the greatest of: 50% above a jurisdiction’s minimum density, three times the density allowed by general plan/zoning/state law, or the density specified in the housing element; in specified high‑opportunity or transit locations the statute adds up to 35 additional units per acre to that calculation.

3

Affordable units required or dedicated under the statute must remain affordable for 55 years for rental units and 45 years for owner‑occupied units, with unit counts for deeply affordable categories counted toward density‑bonus eligibility.

4

When a local agency alleges a project is inconsistent with local rules, it must provide written documentation within 30 days for projects of 150 units or fewer, and within 60 days for larger projects; failure to do so causes the project to be deemed consistent.

5

Several CEQA‑related enforcement provisions and rules about CEQA determinations (including certain judicial burdens and inoperability dates) are expressly set to become inoperative on January 1, 2031.

Subdivision (d)

New limits on when a local agency may disapprove affordable housing or shelters

This provision constrains local disapprovals of projects for very low, low, or moderate‑income households and emergency shelters by requiring the agency to make written findings supported by a preponderance of the evidence showing a specific, adverse public‑health or safety impact that cannot be mitigated without making the project unaffordable or infeasible. It also lists narrow exceptions—e.g., land zoned for agriculture with inadequate utilities—and excludes certain items (zoning inconsistency; welfare tax exemption eligibility) from qualifying as a ‘specific, adverse impact.’ Practically, planning staff will need to build a documented evidentiary record whenever they deny or materially condition such projects.

Subdivision (f) and paragraph (6) of subdivision (h)

Objective standards, development standards, and builder’s‑remedy mechanics

The bill reiterates that local agencies may impose objective, quantifiable, written development standards so long as they facilitate the proposed density. For builder’s‑remedy projects it prescribes exactly which objective standards apply, prevents agencies from imposing ad hoc or additional requirements because a project used the builder’s remedy, and preserves density bonuses and extra incentives for qualifying projects. Those mechanics give developers clearer predictability about which local rules will apply and limit the agency’s ability to use design review or fee increases to defeat a builder’s‑remedy application.

Subdivision (h)(11)

Builder’s‑remedy eligibility and density calculations

This definition sets the conditions for a project to qualify as a builder’s remedy: the jurisdiction lacked a compliant housing element when the application was deemed complete, the project dedicates units to lower‑income households, and the project’s density falls within explicit numeric tests (50% above minimum density, three times allowed density, or housing‑element density), with an additional upward adjustment (up to +35 units/acre) for certain transit‑adjacent or opportunity areas. The provision also contains site suitability limits (e.g., proximity to heavy industrial uses) and minimum density rules for sites near commuter or heavy rail, which affect both eligibility and the unit count used in density‑bonus calculations.

Subdivision (k)–(m)

Enforcement, remedies, attorney’s fees, and fines

The statute expands who may sue (applicants, potential residents, and qualifying housing organizations) and directs courts to compel compliance where violations are proven, including orders to approve projects or to vacate local decisions. The court must award reasonable attorney’s fees to prevailing plaintiffs except in narrow, rare circumstances. If an agency fails to comply with a court order, fines equal to at least $10,000 per unit are imposed and must be funneled to housing trust funds; courts may multiply fines for bad‑faith conduct and for repeat violations. Municipal counsel should plan for heightened litigation exposure and potential fiscal consequences.

Subdivision (o)

Protections against new local ordinances after a preliminary application

SB 681 largely freezes the set of ordinances, policies, and standards that may be applied to a project to those in effect when a complete preliminary application was filed, with enumerated exceptions (automatic fee indexers, post‑application measures necessary to avoid specific adverse public‑health or safety impacts or CEQA impacts, lapse/commencement rules, and large project revisions). This provision narrows the grounds on which agencies can retroactively subject a project to new requirements, but it contains several technical exceptions that will require careful administrative tracking and project timing strategies.

Definitions (g) and (h) — objective, deemed complete, affordability

Tighter definitions to guide review and litigation

The bill clarifies key terms: ‘objective’ (no personal or subjective judgment), ‘deemed complete’ (ties to preliminary application or complete application rules), and the affordability timeframes for deed restrictions (55 years for rental, 45 years for ownership). Those definitions will be central in both administrative determinations and courtroom disputes because the statute repeatedly references them as the baseline for consistency, mitigation, and eligibility determinations.

Who Benefits and Who Bears the Cost

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.

Who Benefits

  • Affordable‑housing developers: Clearer builder’s‑remedy density tests, guaranteed access to density bonuses, and limits on post‑application imposition of new local rules reduce planning risk and can speed approvals for projects targeting lower‑income households.
  • Low‑ and moderate‑income households and emergency‑shelter seekers: By narrowing local grounds for denial and directing fines toward affordable housing, the bill aims to increase the pipeline of deeply and moderately affordable units and shelter capacity.
  • Housing advocacy organizations and pro‑housing attorneys: Expanded standing to sue and a stronger fee‑shifting framework increase their leverage to enforce state housing priorities in local jurisdictions.
  • Developers using density bonuses: The statute counts affordable units toward density‑bonus eligibility and promises additional incentives for qualifying builder’s‑remedy projects, improving project economics for mixed‑income developments.

Who Bears the Cost

  • Local governments and planning departments: Higher litigation exposure, the burden of proving denials with a preponderance of evidence, increased administrative workload to document decisions, and potential financial liability from per‑unit fines and multiplied penalties for bad faith.
  • Municipal budgets and taxpayers: Large fines deposited in housing trust funds or the state trust could strain local fiscal plans and redirect resources reserved for other local programs; repeated violations magnify the fiscal impact.
  • Opposition groups and neighborhood associations: Reduced local discretion over land use means community actors will have fewer regulatory levers to shape neighborhood outcomes, increasing reliance on litigation and political advocacy.
  • Courts and counsel: The statute’s streamlined judicial remedies, tighter filing windows, and potential for high‑stakes orders will increase demand on trial courts and on land‑use litigators, driving resource allocation for case management.

Key Issues

The Core Tension

The bill confronts a classic trade‑off: accelerate the production of affordable housing by narrowing local discretion and increasing judicial enforcement, or preserve local control to address site‑specific health, safety, environmental, and community concerns; SB 681 favors statewide housing outcomes at the expense of local regulatory flexibility, leaving courts and administrators to reconcile competing priorities in technical, evidence‑driven disputes.

SB 681 heightens state control over local land‑use decisions in the name of accelerating affordable housing, but that central objective creates predictable implementation challenges. First, courts will be asked to parse technical concepts—what precisely constitutes a “specific, adverse impact” tied to public health or safety, or when compliance would render a project “unaffordable.” Those determinations require standardized evidentiary practices; absent clear administrative guidance, litigation will increase as the mechanism for resolving inherently policy‑laden disputes.

Second, the builder’s‑remedy density formulas and the treatment of density bonuses reduce some unpredictability for developers but invite compliance and measurement disputes. Determining the applicable baseline densities, calculating the 35‑units‑per‑acre adjustment in opportunity/transit locations, and applying minimum density rules near commuter/heavy rail will require careful mapping, census‑tract analysis, and possibly new local procedures.

Third, the bill’s financial remedies—large per‑unit fines and multipliers for bad‑faith conduct—create a blunt fiscal pressure on localities that may generate unintended consequences, such as localities shifting costs elsewhere or increasing discretionary fees that are still permitted.

Finally, the statute contains a complex mix of temporally limited CEQA‑related provisions and transitional rules for pre‑2025 projects. That temporary architecture could produce a two‑tiered universe of project rights and obligations, complicating project risk assessments.

Implementation depends heavily on secondary actions—HCD forms and definitions, local checklist practices, and consistent administrative recordkeeping—areas where funding, training, and guidance will determine whether the statute speeds housing production or simply increases litigation and compliance costs.
