SB 655 adds Section 17914 to the Health and Safety Code and declares as state policy that dwelling units must be capable of attaining and maintaining a safe maximum indoor temperature. The text directs relevant state agencies to take that policy into account when they revise, adopt, or establish policies, programs, and criteria, including grant criteria.
The bill stops short of prescribing a numeric temperature or enforcement mechanism; instead it creates a cross-agency requirement to integrate thermal-safety objectives into future regulatory and program decisions. For compliance officers, developers, and housing program managers, the bill signals that building standards, grant scoring, and program design will need to align with indoor-heat safety goals going forward — and that agencies will have a specific deadline to begin folding the policy into formal regulations.
At a Glance
What It Does
SB 655 declares a statewide policy that dwelling units be able to attain and maintain a safe maximum indoor temperature and requires relevant state agencies to consider that policy when updating policies, programs, and criteria (including grant criteria). Beginning January 1, 2027, agencies must also consider the policy when revising or adopting regulations that are relevant to achieving it.
Who It Affects
The measure directs state agencies that touch housing and building standards—such as the Department of Housing and Community Development and bodies that influence the California Building Standards Code—as well as agencies that administer housing, health, energy, or disaster-preparedness grants. Landlords, affordable housing developers, and tenants will feel the downstream effects as programs and regulations evolve.
Why It Matters
Although declaratory rather than prescriptive, the law changes the rulemaking lens for multiple agencies: grant criteria, program eligibility, building-code proposals, and regulatory reviews must now account for indoor-heat safety. That reorientation can drive retrofit funding, influence building-code amendments, and alter compliance obligations without a single numeric standard being added to the code today.

What This Bill Actually Does
SB 655 does one focused thing: it writes into the Health and Safety Code a state policy that dwelling units must be capable of reaching and holding a ‘safe maximum indoor temperature.’ The phrase is a policy trigger rather than a technical specification—the bill does not define a temperature threshold or prescribe how to achieve it. Instead the law pushes that policy into the rulemaking and program-management workstreams of state agencies.
Concretely, the bill requires state actors to factor this policy into the design and revision of policies, programs, and criteria, explicitly calling out grant criteria as an example. That wording means agencies that fund housing, energy efficiency, or public-health interventions will need to ask whether their programs help dwellings reach the bill’s thermal-safety objective.
The measure then imposes a regulatory clock: starting January 1, 2027, agencies must also consider the policy when they adopt or amend regulations relevant to achieving it.Because SB 655 is a declaratory policy, its immediate legal effect is to change administrative decisionmaking rather than create a private right or direct enforcement mechanism. The practical pathway from policy to on-the-ground change runs through agencies’ program rules, grant scoring, building-standard proposals, and any guidance they issue.
That means the bill’s impact will depend on subsequent regulatory action, funding choices, and whether the California Building Standards Commission and Department of Housing and Community Development translate the policy into code amendments or program requirements.The absence of a numeric cap or specified compliance test is both deliberate and consequential. Agencies will face choices about defining what constitutes a ‘‘safe maximum’’ and how to measure ‘‘able to attain and maintain’’ that temperature in different building stock.
Those technical decisions will shape whether the policy produces modest changes in grant prioritization and guidance or substantial new retrofit, ventilation, and cooling requirements for existing housing.
The Five Things You Need to Know
SB 655 adds Section 17914 to the Health and Safety Code, declaring as state policy that dwelling units must be able to attain and maintain a safe maximum indoor temperature.
The bill directs all relevant state agencies to consider that policy when revising or establishing policies, programs, and criteria, and it explicitly names grant criteria as a covered element.
Beginning January 1, 2027, agencies must also consider the policy when revising, adopting, or establishing regulations relevant to achieving the safe-temperature objective.
SB 655 does not set a numerical maximum temperature, specify compliance tests, create new enforcement tools, or appropriate funding—its effect is to reframe agency decisionmaking.
The provision is positioned to influence the California Building Standards Code and housing-related grant programs through downstream rulemaking by HCD, the Building Standards Commission, and other agencies.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
State policy: dwelling units must attain and maintain a safe maximum indoor temperature
This is the substantive insertion into the Health and Safety Code. The text establishes the policy objective—thermal safety in dwellings—without specifying technical criteria. That form of legislative language functions as a directive to agencies: it signals a legislative priority that administrative actors must weigh when carrying out their statutory duties.
Requires agencies to integrate thermal-safety into program and policy design
The bill requires 'relevant state agencies' to consider the policy when they revise, adopt, or establish policies, programs, and criteria. Highlighting grant criteria means agencies that fund housing, energy, or health interventions will likely need to adjust eligibility tests, scoring metrics, and program priorities to favor projects that help housing meet thermal-safety objectives.
Regulatory consideration requirement begins January 1, 2027
The statute draws a line between administrative actions and formal rulemaking: while agencies must consider the policy immediately when shaping programs, they have an explicit start date—January 1, 2027—for folding the policy into regulation-making processes. That gives agencies a planning window but also creates a hard point after which regulations should reflect the policy.
Signals future building-code and housing-rule changes without immediate code amendments
SB 655 interacts with existing law that governs the California Building Standards Commission and the Department of Housing and Community Development. The statute does not itself alter the code but makes indoor-heat safety a stated priority that HCD, CBSC, and other agencies must consider as they propose amendments, supplements, or new standards in their regular cycles.
Declaratory policy without funding or direct enforcement provisions
The bill contains no appropriation and does not create a private cause of action or administrative penalty structure. Its leverage comes from administrative incorporation—grant criteria, regulatory standards, and program rules—so the degree of change will turn on agency rulemaking, budget allocations made elsewhere, and how aggressively agencies prioritize the policy.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Vulnerable tenants (elderly, infants, medically fragile) — clearer state policy raises the chance that housing programs and building standards will prioritize their protection from extreme indoor heat.
- Public-health agencies and emergency responders — a coordinated policy makes it easier to align prevention funding (e.g., cooling interventions) with heat-health goals.
- Housing advocates and tenant-rights organizations — the policy gives advocates a statutory lever to press agencies and funders to prioritize cooling and retrofits in low-income housing.
- Residents of code-upgraded housing — when agencies translate the policy into programs and grants, occupied units that receive retrofits or new construction could see measurable indoor-temperature improvements.
Who Bears the Cost
- Landlords and private property owners — if agencies adopt standards or condition grants on cooling-capable housing, owners may need to invest in HVAC, insulation, or ventilation upgrades.
- Affordable-housing developers and rehab projects — meeting new program or regulatory expectations could raise development costs and complicate financing for low-income projects.
- State agencies (HCD, CBSC, energy and health agencies) — departments must dedicate staff time and potentially rulemaking resources to integrate the policy into programs and regulations.
- Utility programs and ratepayers — expanded cooling or retrofit incentives will draw on energy-efficiency and rebate funds, with implications for program budgets and utility planning.
- Tenants indirectly — some costs of required upgrades could be passed through to tenants over time via rent adjustments or higher operating costs unless offset by subsidies.
Key Issues
The Core Tension
The central dilemma is balancing urgent health protection against indoor heat with the financial, technical, and climate costs of delivering cooling across an older and diverse housing stock—SB 655 pushes the policy choice to agencies but does not resolve whether the state will pay for the fixes, set uniform technical standards, or accept uneven implementation.
SB 655 is deliberately light on technical detail: it creates a policy obligation but leaves definition, measurement, and enforcement to agencies. That design eases legislative passage but shifts hard choices—what temperature counts as ‘safe,’ how to measure ‘able to attain and maintain,’ and which buildings must comply—to the administrative process.
Those technical determinations will determine whether the policy produces surface-level shifts in grant priorities or substantial regulatory obligations that require retrofits.
The bill also sets up a policy trade-off between public-health protection and energy/climate objectives. Expanding cooling capability across the housing stock can reduce heat-related illness but increase electricity demand and greenhouse-gas emissions if not paired with efficiency measures and decarbonized power.
Finally, because SB 655 includes no funding, agencies or the Legislature must choose whether to attach money to new requirements; absent funding, implementation could be uneven and could disproportionately burden older buildings and resource-constrained landlords, which risks leaving the most vulnerable populations behind.
