Last updated: October 12, 2026. Statutes and regulations checked for the state provisions below. This guide covers hospital staffing, not a separate review of nursing-home staffing laws.
Quick answers about mandated nurse ratios
- California is not the only state with enforceable staffing ratios. Its hospital unit requirements differ from Oregon's ratios and the ICU-specific rules in Massachusetts and New York.
- New York's staffing legislation dates to 2021. The explicit ICU/critical-care 1:2 RN requirement is in the regulation adopted in July 2023.
- Oregon's medical-surgical 1:4 requirement is already operative. The current statute gives July 1, 2026 as the operative date of that version.
- A ratio is a staffing minimum or patient-assignment ceiling, not permission to ignore a patient's need for closer observation.
Hospital staffing laws by state
Table checked October 12, 2026. Each row links the governing provision. These are the states discussed in this guide, not a finding that every unlisted state has no staffing requirements. Hospital licensure rules, specialty-unit standards, contracts and subsequent amendments can add obligations.
| State | Type of rule | What it requires | Statute or regulation |
|---|---|---|---|
| California | Unit-specific hospital ratios | General acute care hospitals use unit-specific minimum licensed-nurse ratios. Patient acuity can require more staff. | HSC § 1276.4; 22 CCR § 70217 |
| Oregon | Unit-specific RN ratios | ICU: no more than two patients per direct care RN. Medical-surgical: no more than four under the version operative July 1, 2026. Statutory exceptions and approved variances matter. | ORS §§ 441.763, 441.765, 441.766 |
| Massachusetts | ICU assignment limit | ICU assignments are 1:1 or 1:2, based on patient stability, the acuity tool and assessment by unit nurses. | M.G.L. c. 111, § 231 |
| New York | ICU/critical-care RN minimum and staffing plans | At least one RN for every two patients determined to need intensive or critical care. General hospitals also develop clinical staffing plans. | PHL § 2805-t; 10 NYCRR § 405.22(b)(5) |
| Connecticut | Staffing committees and plans | Hospitals develop and post staffing plans with direct care RN participation; statutory compliance reporting and enforcement apply. | Conn. Gen. Stat. § 19a-89e |

California: unit-specific requirements
California's Health and Safety Code § 1276.4 directs the adoption of hospital nurse-to-patient ratios. The operational requirements are in Title 22, § 70217. They specify different minimums for different units and require staffing to reflect individual patient care needs.
Keep the facility type in view. A claim about general acute care hospital units should not be stretched into a claim that every hospital, specialty facility or care setting follows one identical rule. For a clinical assignment, check the unit classification and applicable regulation alongside the hospital's staffing and escalation procedures.
Oregon: the summer 2026 change is in force
Under ORS § 441.765, an ICU direct care RN may be assigned no more than two patients. The medical-surgical maximum changed from five patients to four in the statutory version operative July 1, 2026. It is no longer a future change.
The same statute addresses other units, patient classification and staffing-plan deviations. ORS §§ 441.763 and 441.766 describe variances and exceptions. Read those provisions before treating a headline ratio as an absolute rule for every assignment.
The Oregon Health Authority staffing site provides current plans and complaint guidance. A proposed bill is not a replacement for enacted law. For example, 2026 SB 1558 proposed staffing changes, but its listed status is in committee, not an enacted chapter.
New York: the 2021 law and the ICU 1:2 regulation
New York's Public Health Law § 2805-t, added in 2021, requires clinical staffing committees and unit- and shift-specific staffing plans. It also directs regulations for intensive and critical care staffing.
The explicit numerical requirement appears in 10 NYCRR § 405.22(b)(5): at least one registered professional nurse for every two patients an attending practitioner determines need intensive or critical care. The July 19, 2023 adoption notice identifies the implementing amendments.
That distinction matters. The staffing law is from 2021; the explicit 1:2 regulatory requirement was adopted in 2023. New York should not be listed only as a state that discloses staffing information.
Massachusetts: ICU assignments depend on acuity
Massachusetts General Laws c. 111, § 231 sets ICU RN assignments at 1:1 or 1:2 according to patient stability, the hospital's acuity tool and assessment by unit nurses. 958 CMR 8.00 explains implementation.
Do not reduce this to either “every ICU nurse always has one patient” or “two patients are always permitted.” The acuity assessment determines the assignment under the rule.
Staffing committees, plans and reporting are different tools
A staffing committee gives frontline staff a role in developing the hospital's plan. A plan sets staffing for that hospital's units and shifts. Public reporting lets patients and staff see staffing information. None automatically means the legislature has prescribed the same numerical ratio for every hospital unit statewide.
Committee membership also varies by statute. The old shortcut that every committee must be at least half direct care RNs is too broad. New York includes other frontline team members; Nevada's statute includes licensed nursing staff and certified nursing assistants. Use the linked statute for the state you are researching.
For Washington, Department of Health guidance explains the staged dates: staffing-plan implementation and unit posting began in July 2025, and specified hospitals began semiannual compliance reporting in January 2026. That is a plan-compliance system, not California's unit-ratio model.
How to use this information on a shift
Before accepting or escalating an assignment, identify the facility type, unit, patient acuity and applicable staffing plan. Document the specific concern through your hospital's process, including the care demand that cannot be met. Follow the relevant state agency's complaint guidance and your employer's escalation policy.
If you are comparing jobs, ask to see the unit's staffing plan and how the hospital covers breaks, admissions and changes in patient condition. Our guide to the benefits of staffing ratio laws covers the broader context. For state practice requirements, start with the Oregon licensure guide and the state's own licensing authority.
Frequently asked questions
Is California the only state with mandated nurse-to-patient ratios?
No. Oregon also has statutory unit-specific ratios. Massachusetts and New York have ICU or critical-care requirements. Their scope and exceptions differ, so read the provision for the unit rather than treating all four systems as identical.
What changed in Oregon in 2026?
The medical-surgical ceiling became four patients per direct care RN in the ORS § 441.765 version operative July 1, 2026. The prior version permitted five. The statute also contains exceptions and staffing-plan rules.
Does New York require one ICU nurse for every two patients?
Its regulation requires at least one RN for every two patients determined to need intensive or critical care. The enabling staffing law was enacted in 2021; the explicit 1:2 regulation was adopted in July 2023.
Is there one federal hospital nurse-to-patient ratio?
42 CFR § 482.23 requires adequate nursing personnel and RN availability under the hospital conditions of participation. It does not create one universal numerical ratio for all hospital units. Nursing-home requirements are a separate subject.
