SB 340 amends California’s housing element law (Gov. Code §65583) and the Emergency Housing and Assistance Program definition (Health & Safety Code §50801) to tighten how jurisdictions plan for emergency shelters.
The bill requires housing elements to identify one or more zoning designations where emergency shelters are allowed as a permitted use (no discretionary permit), to adopt a short list of written, objective standards that apply to shelters, and to include all onsite services (including additions or expansions consistent with those standards) in the housing element’s inventory and analysis.
The law also revises the statutory definition of “emergency shelter” to require supportive services and preserves several compliance and enforcement tools: minimum site‑capacity calculations for planning (200 sq. ft. per person), multijurisdictional agreements for shared shelters, rezoning deadlines and developer protections if rezoning is not completed, CEQA non‑discretionary status for permit processing standards, and a state‑mandated local program reimbursement trigger if costs are determined eligible. The changes reallocate practical and fiscal responsibilities between local governments, service providers, and the state, and they introduce new implementation questions (funding, service scope, and HCD review standards).
At a Glance
What It Does
Mandates that housing elements identify zones permitting emergency shelters by right and adopt a short set of written, objective standards that govern shelters. Requires housing elements to inventory and describe all onsite services (including planned additions/expansions consistent with those standards) and updates the statutory definition of emergency shelter to require supportive services.
Who It Affects
City and county planning departments, local elected bodies responsible for housing elements, emergency shelter operators and nonprofit service providers, developers of shelters/supportive housing, and the Department of Housing and Community Development (HCD) which reviews compliance.
Why It Matters
It converts policy direction into land‑use mandates that reduce local discretion over where shelters can locate and what rules apply. That increases the likelihood of new shelter capacity but also shifts operational and fiscal burdens—particularly the need to provide or fund onsite supportive services—onto local governments and providers.

What This Bill Actually Does
SB 340 rewrites parts of the housing‑element statute to force clearer, more prescriptive local planning for emergency shelters. Each jurisdiction must identify at least one zoning designation where emergency shelters are allowed as a permitted use (no conditional‑use or other discretionary permit).
The law requires that identified zones have sufficient sites (or a program to rezone within a year) to meet the jurisdiction’s assessed shelter need. If jurisdictions rely on multijurisdictional agreements, they must secure and describe shared shelter capacity and show how capacity is allocated among participating jurisdictions.
The bill narrows the range of permissible local rules for shelters by listing only a short set of written, objective standards that may apply (for example: maximum beds, staff parking, waiting/intake area size and location, onsite management, proximity to other shelters up to a 300‑foot spacing, length of stay, lighting, and security). Importantly, housing elements must describe all services provided onsite for those shelters and must state whether additions or expansions of services are consistent with the local objective standards.For planning capacity, SB 340 adopts a 200 square‑foot per person metric for calculating how many unhoused people a site can accommodate, while allowing jurisdictions to present evidence if prior shelters used a smaller footprint.
The statute also creates a presumption that nonvacant sites impede shelter development unless substantial evidence shows the existing use is likely to end during the planning period. Permit processing and the management standards under the shelter provisions are not discretionary acts for CEQA purposes, limiting CEQA as a grounds to block objective permitting standards.The bill preserves enforcement and compliance mechanics: rezoning deadlines tied to the housing element cycle, an explicit prohibition on disapproving otherwise‑compliant housing projects located on sites required to be rezoned (with narrow exceptions for specific, quantifiable public health or safety impacts), and judicial remedies that allow courts to compel compliance within short timelines.
Finally, SB 340 amends the Emergency Housing and Assistance Program definition to require that emergency shelters include supportive services and notes that if the Commission on State Mandates finds the law creates reimbursable costs, reimbursement shall follow established statutory procedures. The bill also contains conditional operative language coordinating its provisions with AB 610 and AB 650 if those bills also amend the same section.
The Five Things You Need to Know
The bill redefines “emergency shelter” in Health & Safety Code §50801 to mean housing limited to six months’ occupancy that includes supportive services; no one may be denied shelter for inability to pay.
Housing elements must identify zoning designation(s) where emergency shelters are allowed as a permitted use (no discretionary permit) and include sufficient sites to meet the assessed need or a program to rezone within one year.
Jurisdictions may subject shelters only to a short, enumerated list of written, objective standards (e.g.
max beds, staff parking, intake/waiting area size/location, onsite management, proximity up to 300 feet, length of stay, lighting, security); those standards are not discretionary acts for CEQA.
The planning capacity formula uses a minimum of 200 square feet per person to convert site area into shelter capacity for housing‑element calculations, with a process for jurisdictions to justify deviations based on past development evidence.
If a jurisdiction fails to complete required rezonings by the statute’s deadlines, it generally may not disapprove a housing development on a rezoning site that complies with objective standards; courts may enforce compliance and can compel agencies to act within 60 days.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Requires zoning designations that allow emergency shelters by right and adequate site capacity
This provision requires each housing element to identify one or more zoning designations where emergency shelters are allowed as a permitted use without conditional‑use or other discretionary permits. Those zoning designations must include sites that meet defined standards (vacant residential, vacant nonresidential that permits residential, or nonvacant with demonstrated redevelopment potential) and in aggregate must have capacity to accommodate the jurisdiction’s assessed shelter need. If the jurisdiction lacks sufficient capacity, the housing element must include a program to amend the zoning ordinance within one year. The rule changes the starting point for local shelter siting from discretionary decisionmaking to an affirmative, by‑right planning requirement.
Limits local regulation to a short list of written, objective standards and removes CEQA discretion
SB 340 enumerates the only written, objective standards that jurisdictions may use to regulate emergency shelters (maximum beds/persons, staff parking parity, intake/waiting area sizing and location, onsite management, proximity spacing up to 300 feet, length of stay, lighting, and security). The statute further provides that applying those permit processing, development, and management standards is not a discretionary act under CEQA, insulating objective permit processing from CEQA‑based delay litigation and reinforcing a ministerial pathway for shelter approvals.
Requires housing elements to list onsite services and sets a 200 sq. ft. per person planning metric
The housing element must describe all services provided onsite at emergency shelters and may include planned additions or expansions so long as they align with the jurisdiction’s written, objective standards. For capacity calculations, the bill uses a 200 square‑foot per person divisor to convert site area into shelter capacity for meeting shelter need; jurisdictions can rebut or refine that metric with evidence from prior development. The statute also creates a presumption that existing occupied uses on nonvacant sites impede shelter development unless substantial evidence shows discontinuation is likely during the planning period.
Permits regional shelter agreements; protects developers when rezoning deadlines slip
Jurisdictions may satisfy shelter‑site requirements via multijurisdictional agreements (maximum of two adjacent communities) that commit to at least one year‑round shelter within two years and allocate capacity credits. Separately, if a jurisdiction fails to complete required rezonings by statutory deadlines, it generally cannot disapprove housing projects proposed on sites required to be rezoned provided the project complies with applicable objective standards. A narrow exception allows disapproval when a project would create a specific, adverse public health or safety impact that cannot be mitigated; such findings must be supported by substantial evidence.
Redefines emergency shelter to require supportive services and sets operability conditions with AB 610/650; state mandate language
SB 340 amends §50801 to define emergency shelter as housing with supportive services limited to six months’ occupancy and clarifies that no one may be denied shelter due to inability to pay. The bill includes detailed operative sequencing clauses: alternate versions of the §65583 amendments will take effect only if SB 340 and AB 610 and/or AB 650 are enacted and SB 340 is enacted last, and different text becomes operative depending on which partnering bills pass. Finally, it directs that if the Commission on State Mandates determines the measure imposes reimbursable local costs, reimbursement will be made under existing statutory procedures.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- People experiencing homelessness: The law pushes jurisdictions to plan for more year‑round shelter capacity and requires shelters to include supportive services, which can shorten time to services and housing exits.
- Shelter and supportive‑services providers: Clearer, by‑right siting rules reduce discretionary permitting delays and provide a transparent checklist of objective standards to design to.
- Regional coalitions of local governments: Multijurisdictional agreements are recognized and can be used to meet shelter obligations and share capacity and costs across adjacent jurisdictions.
- Developers of shelter or supportive housing: The restriction on disapproving projects on rezoning sites (when jurisdictions miss deadlines) creates a more predictable approval path for projects that meet objective standards.
Who Bears the Cost
- Cities and counties (planning and zoning departments): Must identify by‑right zones, perform new analyses and inventories, prepare rezoning programs when needed, and potentially change land‑use codes—work that consumes staff time and local budget.
- Shelter operators and nonprofit providers: Must provide supportive services onsite (or expand services) as part of shelters counted in housing elements, increasing operating costs unless offset by new funding.
- Local budgets/taxpayers: Operational expenses for added shelter capacity and onsite supportive services (case management, health/navigation) may fall to local general funds if state or philanthropic funding is insufficient.
- Property owners and nearby residents: Increased by‑right siting of shelters may raise local concerns about neighborhood impacts, and owners of nonvacant sites may see redevelopment pressure or incentives to change use.
Key Issues
The Core Tension
The bill forces a tradeoff between expanding shelter capacity quickly (by restricting local discretion and enabling by‑right siting) and the practical realities of delivering supportive services and paying for operations; increasing site certainty without matching operating funds or defining service standards risks creating more physical shelter beds than fully functional, service‑integrated programs.
SB 340 tightly links land‑use mandates to service obligations, but it leaves key implementation details unresolved. The statute requires jurisdictions to describe all onsite services and permits additions or expansions that are “consistent with” written, objective standards, yet it does not define the substantive scope, staffing levels, or funding expectations for those supportive services.
That ambiguity raises the risk that jurisdictions will identify sites but then struggle to operationalize shelters because providers cannot cover ongoing service or operating costs.
The law’s 200 sq. ft. per person planning metric is explicitly for housing‑element capacity calculations, not a development standard, but in practice that number may become a political or administrative cap used by opponents to limit actual shelter size or to argue against alternative designs. The presumption that occupied nonvacant sites impede shelter development shifts the evidentiary burden toward jurisdictions to show redevelopment potential, a test that will invite disputed factual fights with developers and property owners.
The CEQA non‑discretionary language accelerates approval pathways but shifts pressure to get objective standards right up front; unclear or poorly drafted standards will generate litigation under other legal theories (e.g., constitutional takings or state housing law claims).
Finally, the bill’s conditional operability with AB 610 and AB 650 creates complexity: different textual versions of the same statutory section may take effect depending on enactment order, which complicates compliance guidance from HCD and increases the risk of inconsistent local implementation. The Commission on State Mandates reimbursement trigger means localities should track incremental costs for potential claims, but reimbursement timelines and sufficiency are uncertain—leaving a funding gap between new obligations and available reimbursement or program funding.
