AB 906 amends the statutory content of California housing elements to require localities to identify adequate sites and zoning that allow emergency shelters as a permitted use (without a conditional use or other discretionary permit), adopt written objective standards that apply only to shelters, and demonstrate sufficient site capacity to meet shelter needs. The bill also tightens rezoning schedules when inventories fall short, creates a limited multijurisdictional shelter-credit option, and links site selection to affirmative furthering of fair housing obligations.
This is a procedural and substantive shift: jurisdictions must proactively designate and, where necessary, rezone sites to accommodate emergency shelters and show how housing element programs affirmatively further fair housing. The bill adds concrete capacity calculations, a narrow list of permissible objective standards for shelters, enforcement tools that constrain local discretionary authority when rezoning is overdue, and specific preservation and planning requirements for assisted and supportive housing.
Local planning departments, shelter operators, affordable housing developers, and municipal counsel will need to change practices to comply.
At a Glance
What It Does
Requires housing elements to identify zoning where emergency shelters are permitted by‑right and to include written, objective standards that apply only to shelters; sets methods to calculate site capacity; establishes deadlines and processes for required rezoning; and requires programs that affirmatively further fair housing and preserve assisted housing.
Who It Affects
Cities and counties preparing housing elements, shelter operators and providers seeking by‑right siting, affordable housing and supportive housing developers, regional collaborators using multijurisdictional agreements, and legal counsel who will litigate or defend compliance disputes.
Why It Matters
The bill reduces discretionary barriers for siting emergency shelters, forces jurisdictions to reconcile shelter siting with fair housing obligations, creates enforceable rezoning timelines, and increases the risk that noncompliant localities will be required to approve qualifying developments despite local opposition.

What This Bill Actually Does
AB 906 keeps the housing element’s longstanding mandate to inventory housing needs and resources, but inserts detailed, operational requirements aimed at emergency shelter capacity and fair housing outcomes. Localities must identify one or more zoning designations in which emergency shelters are allowed as a permitted use without a conditional use or other discretionary permit; where sufficient capacity is not available they must include a program to amend zoning within one year of housing element adoption.
The statute explicitly allows jurisdictions to treat certain shelter‑adjacent interventions—navigation centers, bridge housing, respite/recuperative care—as emergency shelters for these requirements.
The bill limits what rules a locality may impose on emergency shelters to written, objective standards and it lists the permissible categories of standards (for example, maximum nightly beds, staff parking, intake area size/location, onsite management, proximity limits, length of stay, lighting, and security). Those standards are not to be treated as discretionary acts under CEQA.
Site eligibility rules require that sites either be vacant and zoned residential, vacant nonresidential parcels that allow residential uses and are near services (or paired with guaranteed transportation/services), or nonvacant sites that can be demonstrated—on substantial evidence—to be likely available or redevelopable during the planning period.To measure capacity, AB 906 adopts a default metric: divide site square footage by 200 square feet per person unless the locality can show prior experience or other evidence that a different ratio applies. The statute also allows local governments to claim local‑government‑owned sites if they can show the sites will be made available and are near services.
Where an inventory shortfall exists, the housing element program must specify rezoning actions, and the bill sets out concrete deadlines for those rezonings tied to the element cycle (including accelerated deadlines when jurisdictions miss adoption milestones).The bill preserves several existing, related duties and adds operational detail. Jurisdictions must analyze governmental and nongovernmental constraints, plan for preservation of assisted housing (including listing at‑risk developments and estimating replacement costs), promote accessory dwelling units that can be offered at affordable rents, and make supportive housing a use by right where multifamily and mixed uses are permitted.
If a jurisdiction fails to complete required rezonings by the statutory deadline (subject to limited extensions), it may not disapprove qualifying housing development projects on those sites nor impose discretionary conditions that render projects infeasible; a developer must, however, commit to keeping at least 49 percent of units affordable to very low, low, and moderate incomes under the applicable financing period to benefit from this protection. The statute provides for judicial enforcement and lets courts compel compliance within set timeframes.
The Five Things You Need to Know
The bill requires at least one zoning designation in each jurisdiction that permits emergency shelters as a permitted use without a conditional use or other discretionary permit and obligates a rezoning program if capacity is insufficient.
Localities must restrict shelter rules to written, objective standards and may only regulate items listed in the statute (e.g.
maximum beds, staff parking not exceeding comparable uses, intake areas, onsite management, proximity—no required separation greater than 300 feet—length of stay, lighting, and security).
Site capacity is calculated by dividing site square footage by 200 square feet per person unless the locality supplies evidence that a different ratio applied successfully in the prior planning period.
If a jurisdiction’s housing element lacks adequate sites, rezoning deadlines are tightened: accelerated schedules apply for sixth and subsequent revisions (including one‑year or three‑year targets depending on circumstances) and rezoning must occur within one year where a jurisdiction misses statutory adoption deadlines.
When required rezonings are incomplete, a local government may not disapprove or impose discretionary permits that render feasible, compliant housing projects infeasible; the statute creates a private enforcement path and directs courts to compel compliance, with a 60‑day deadline to carry out orders.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Mandatory identification of by‑right shelter zoning and objective standards
This section requires housing elements to identify one or more zoning designations that allow emergency shelters as a permitted use without discretionary permits and to demonstrate sufficient capacity to meet the shelter need. It also mandates written, objective permit, development, and management standards that specifically apply to shelters and lists permissible standard categories. Practically, planners must either point to existing objective ordinances or draft new objective standards; they must also show how permit processing is structured so shelters are facilitated rather than delayed.
Site eligibility rules and local‑government‑owned site option
The bill sets out three categories of acceptable sites: vacant residentially zoned parcels, vacant nonresidential parcels that allow residential development and are near services (or paired with transportation/services), and nonvacant parcels that can be redeveloped during the planning period. For local‑government‑owned land, jurisdictions may count those parcels if they can show they will make the sites available and they are near services. These mechanics force planners to be explicit about site selection and the nexus between shelter siting and access to services.
Capacity calculation for shelters
To quantify how many people a site can serve, the statute prescribes dividing site square footage by a minimum of 200 square feet per person as the default metric for planning capacity. Jurisdictions may deviate from the default only with evidence of prior successful shelters at higher densities or other convincing evidence to the department. The law clarifies that the calculation is only for planning capacity and is not a development standard for a particular project.
Constraint analyses and assisted‑housing preservation
AB 906 requires jurisdictions to analyze governmental and nongovernmental constraints (land use controls, fees, historic designations, financing availability, cost of construction, and timing lags between approvals and permit submittals). It also requires listing assisted housing at risk of conversion, estimating replacement and preservation costs (aggregated for five‑year periods), and identifying nonprofit or public entities with capacity to acquire and manage at‑risk properties. These items make preservation planning and financial analysis a formal part of the housing element.
Programs: rezoning, ADUs, supportive housing, and fair housing linkage
The program element must specify actions and timelines, including rezoning where inventories fall short, measures to assist housing at all income levels (and acutely low income in later revisions), plans to incentivize affordable ADUs, and confirm that supportive housing is a use by right where multifamily or mixed uses are permitted. Importantly, site designation and required rezoning must affirmatively further fair housing as determined under Section 65583.2 and related statutes, tying technical zoning choices to civil‑rights–oriented outcomes.
Multijurisdictional agreement option
Jurisdictions may form a multijurisdictional agreement with up to two adjacent communities to develop at least one year‑round shelter within two years of the planning period start and allocate shelter capacity credits to participating jurisdictions. Each housing element must describe how the joint facility meets local needs, each jurisdiction’s contributions to development and ongoing operations, and funding sources. The aggregate credit claimed by jurisdictions cannot exceed the facility’s actual capacity.
Rezoning deadlines, extensions, and enforcement
AB 906 sets specific rezoning deadlines for different element cycles and provides a one‑year extension if a jurisdiction rezones to accommodate at least 75 percent of lower‑income units and documents narrow circumstances (e.g., agency inaction, infrastructure deficits, or major general‑plan revisions). If required rezonings remain undone, the statute constrains local discretion: jurisdictions may not disapprove qualifying housing projects or require discretionary permits that render them infeasible, subject to a narrow public‑health/safety exception proven with substantial evidence. The law enables private enforcement actions and directs courts to compel compliance and retain jurisdiction until localities implement court orders.
Optional constraint analysis and tribal consultation timing
Starting in 2024 terms, the department may include in the constraint analysis consideration of constraints on housing for persons with characteristics listed in Civil Code Section 51, but only if the Legislature appropriates funds. The bill also contains a dated provision extending Native American tribal response time for certain projects between March 2020 and December 2021; that clause is limited to that historical window and is effectively a transitional/contingent provision.

Explore Housing in Codify Search →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
- People experiencing homelessness: The statute requires explicit planning for emergency shelter capacity, closer proximity to services, and objective standards that reduce discretionary delays.
- Shelter operators and service providers: By creating by‑right shelter zones and objective permit standards, AB 906 reduces permit uncertainty and shortens the path from project concept to operation.
- Affordable and supportive housing proponents: The bill makes supportive housing a use by right in multifamily/mixed zones, mandates preservation analyses for assisted housing, and encourages affordable ADU programs.
- Regional collaborators and nonprofit housing developers: The multijurisdictional agreement option and mandated listings of nonprofit partners create clearer avenues for joint facilities and acquisitions of at‑risk properties.
Who Bears the Cost
- Cities and counties: Local governments must prepare more detailed analyses, adopt or amend objective shelter standards, undertake rezoning within tight timelines, and may face litigation and court orders if they fail to comply.
- Local planning and housing departments: Expect increased workload to produce evidence for site suitability, capacity calculations, preservation cost estimates, and public participation documentation.
- Opponents and adjacent neighborhoods: Communities near identified sites may see increased shelter placement, changing service patterns, and potential concentrated impacts that localities will need to mitigate or justify.
- State Department of Housing and Community Development (and courts): The department will receive more complex submissions to review; courts will see enforcement actions and must monitor compliance if ordered, imposing administrative burdens.
Key Issues
The Core Tension
The central dilemma is between urgent, measurable state goals to produce shelter capacity and fair‑housing outcomes, and local land‑use discretion and political realities: the bill forces jurisdictions to act quickly and provides remedies when they do not, but doing so risks concentrated impacts, litigation, and implementation debates about how to measure capacity and what counts as objective evidence.
AB 906 tightens the procedural scaffolding around housing elements but leaves several implementation details unresolved. The statute repeatedly invokes standards of proof—“substantial evidence,” “suitable for residential use,” or proximity to services—that will require localities to assemble evidence packages and will invite scrutiny from the department and challengers.
The 200‑square‑foot per‑person planning metric is useful for consistency, but shelter models vary widely (dormitory‑style, individual rooms, navigation centers with program space), and the default could undercount capacity for some models or overcount in others; allowed deviations require prior evidence, which creates a catch‑22 for jurisdictions lacking historical shelter projects.
The enforcement regime tilts power to developers and advocates when rezonings lag: courts can compel compliance and bar local disapprovals of qualifying projects, which accelerates housing approvals but may also create political backlash and incentivize piecemeal litigation. The bill also contemplates CEQA non‑discretionary treatment for the listed shelter standards, but the extent to which CEQA challenges will be avoided remains uncertain because challenges could target other local approvals or the substance of standards themselves.
Finally, the multijurisdictional agreement is strictly limited (maximum two adjacent partners and required timeline), which constrains regional approaches for larger metro areas and could incentivize artificial boundary games to allocate shelter credits.
