Nurse-to-Patient Ratios by State: The 2026 Map

Key Takeaways

• Only three states put a nurse-to-patient ratio in law. California and Oregon set ratios across many unit types, and Massachusetts sets one for the intensive care unit only, per the American Nurses Association staffing-law tracker and 22 CCR 70217.
• There is no federal nurse-to-patient ratio. CMS requires “adequate numbers” of nurses matched to patient acuity under 42 CFR 482.23, and a critical access hospital must keep a registered nurse, clinical nurse specialist, or licensed practical nurse on duty whenever it has one or more inpatients under 42 CFR 485.631.
• About a dozen more states require a nurse-led staffing committee or public disclosure of staffing plans, not a fixed ratio. The American Nurses Association counted 16 states with any staffing law as of March 2022, and the majority of states have none.
• Texas is a committee state. Texas Health and Safety Code 257.004 requires a committee that is at least 60 percent direct-care registered nurses and a written, adopted staffing plan, with no statewide ratio.
• For a small Texas hospital, the working standard is the committee’s own plan and whether the schedule and records show that plan was met on every shift, not a number the state never set.
• Ratio laws move. Oregon’s ratios phase in through mid-2026, so an older map that named a single ratio state is already out of date. Treat any state-law claim as a dated snapshot.

Ask what the required nurse-to-patient ratio is, and the honest answer is that it depends on which state you are in. Nurse-to-patient ratios are not the same from one state to the next. A nurse working a 1-to-5 medical-surgical assignment in California crosses into Texas and finds no legal ratio at all, only a staffing plan her hospital’s committee wrote.

This is the 2026 map. It sorts states into three groups, a fixed ratio in law, a staffing committee or disclosure rule, or no staffing law at all, then explains what Texas’s group means for a small hospital that must build a defensible schedule without a state-issued number.

Which States Mandate a Nurse-to-Patient Ratio in Law?

Three states set an actual nurse-to-patient ratio in law. California and Oregon set ratios across many hospital unit types, and Massachusetts sets one for the intensive care unit only. Every other state either requires a staffing committee and plan, requires public disclosure of staffing, or requires nothing at all. Most of the country falls in that last group.

California has the longest-standing comprehensive ratios. Under 22 CCR 70217, the floor is 1 nurse to 5 patients on medical-surgical units, 1 to 2 in the ICU and other critical care, and 1 to 4 in the emergency department, among roughly a dozen unit types, and the numbers apply at all times including breaks. Oregon joined with a 2023 law that phases minimum ratios across hospital unit types through mid-2026, with its medical-surgical floor tightening to 1 to 4 in June 2026, per the Oregon Health Authority. Massachusetts is different: its ratio covers the ICU only, not the whole hospital. The table below sorts the states you can source into three tiers.

The practical read for a rural administrator is that “nurse-to-patient ratio by state” is a real question because the answer genuinely differs by state. If you operate outside California, Oregon, and Massachusetts, you almost certainly have no legal ratio, and building a schedule as if a 1-to-5 rule applied to you is a misread of the law. For how ratios function inside a single 25-bed facility rather than across the map, our companion guide to nurse staffing ratios at a critical access hospital goes deeper on acuity and coverage.

Ratio Law, Committee Law, or Nothing: What Is the Difference?

A ratio law sets a hard number of patients per nurse that a hospital may not exceed. A committee law hands that judgment to a nurse-led committee that writes a plan for the specific hospital. A disclosure law only requires the hospital to publish what it staffs. Below all three sits the federal floor, which is qualitative and applies everywhere.

The federal baseline is where every hospital starts. There is no federal nurse-to-patient ratio. Under 42 CFR 482.23, a general hospital must have “adequate numbers” of registered nurses, licensed practical nurses, and other staff to meet patient needs, judged by acuity rather than a count. A critical access hospital works under a coverage rule instead: 42 CFR 485.631 requires a registered nurse, clinical nurse specialist, or licensed practical nurse on duty whenever the facility has one or more inpatients. It governs who is present rather than how many patients each nurse carries.

On top of that federal floor, some states add their own staffing rule and most add nothing. The American Nurses Association staffing-law tracker counted 16 states with some form of hospital staffing law as of March 2022, grouped into committee states, disclosure states, and the two ratio states it named at the time. The states in each group appear in the table above. The ANA supports both enforceable ratios and nurse-led committees, treating them as complementary tools rather than rivals. What matters for planning is knowing which of the three your state actually imposes, because each one measures compliance differently.

Does Texas Mandate Nurse-to-Patient Ratios?

No. Texas mandates a nurse staffing committee and a written staffing plan, not a ratio. Under Texas Health and Safety Code 257.004, a hospital must establish a committee where at least 60 percent of the members are registered nurses who provide direct patient care, and that committee develops and recommends a written staffing plan the hospital’s governing body adopts.

The plan is where acuity lives. Rather than a statewide number, the committee sets staffing by unit type, patient acuity, skill mix, the experience of the nursing staff, and the layout of the unit. The hospital then follows the plan and keeps records showing it did. In practice a Texas hospital is accountable to its own adopted plan, which a surveyor can ask to see alongside the schedules and staffing records that show the plan was met on a given shift. Overtime is part of that same picture, since a plan met only by pushing the same nurses into repeated extra shifts is not sustainable coverage, a point our guide to Texas nursing overtime compliance covers in detail.

What Does the State Map Mean for a Small Texas Hospital?

For a small Texas hospital, the map means the standard you are held to is the plan your own committee wrote, translated into a schedule that covers every shift at the acuity the plan calls for, backed by records that prove it happened. With no ratio to copy, the plan itself is the yardstick, and the schedule is how you meet it. If the model is new to you, start with what a critical access hospital is and how its rules differ from a larger hospital.

At this size, the hard part is not the math. It is the thin bench. A 25-bed facility may run with 15 to 25 nurses in total, so a plan that looks fine on paper can fall apart the moment two nurses are out and the patients get sicker. The schedule has to build in enough qualified coverage on every shift, including nights and weekends, and it has to flag when a callout would drop a unit below what the plan requires.

Three things make a plan defensible at a small hospital. First, the schedule matches the plan’s skill mix, so the right licenses and competencies are on the floor, not just enough people. Second, callout replacement keeps you at plan instead of pulling whoever is reachable regardless of qualification. Third, every assignment and change is logged, producing the staffing records a surveyor expects when they ask how you met your plan. For choosing a tool that supports all three at this scale, see scheduling software for a 25-bed hospital.

How Does SimpleScheduleAI Help a Small Hospital Staff to Its Plan?

SimpleScheduleAI is an AI-native nurse scheduling service: the AI builds the schedule, our scheduling team checks it, you approve. We build each facility’s committee-approved staffing plan into the scheduling logic, so a draft reflects the skill mix and coverage the committee set, not just a headcount. When the system generates a draft, it checks each shift against those coverage parameters and surfaces where a unit would fall below plan before anyone signs off. You can watch it build a compliant week in the interactive simulator.

When a nurse calls out, the replacement shortlist is drawn from qualified, available staff who keep the unit at plan. For Texas Critical Access Hospitals, the same draft tracks each nurse’s running hours against the applicable FLSA overtime thresholds, so meeting the plan does not quietly push someone into unplanned overtime. Every assignment, callout, and change is logged, which produces the staffing records a survey asks for. The full process lives on our nurse scheduling software page, our critical access hospital scheduling hub, and the walkthrough of how it works. For how an AI-built schedule handles acuity and coverage, see AI nurse scheduling.

One honest limitation: SimpleScheduleAI does not set your staffing plan or interpret your state’s law for you. Your nurse staffing committee decides what adequate staffing is, and we build the schedule that meets it. If a hospital has not adopted a plan yet, that committee work comes first, and no scheduling tool substitutes for it.

What to Do This Week

1. Find your state on the map. If you operate outside California, Oregon, and Massachusetts, you almost certainly have no legal nurse-to-patient ratio, and staffing to a borrowed 1-to-5 rule misreads the law that actually applies to you.
2. If you are in Texas, confirm your hospital has a current nurse staffing committee that is at least 60 percent direct-care registered nurses, and pull the written staffing plan it adopted. Read what it requires by unit and skill mix, not just headcount.
3. Compare last month’s actual schedules against that plan shift by shift. Mark every shift that ran below plan and note why, since those are the shifts a survey would probe.
4. Check that your callout process keeps a unit at plan rather than filling a warm body, and that every change is recorded somewhere retrievable.
5. See how an automated draft would flag below-plan shifts across your specific roster before you publish. Book a call with our team to walk through it.

Frequently Asked Questions

The law by state

Q: Which states have mandated nurse-to-patient ratios in 2026?

Three states set a ratio in law. California and Oregon set minimum nurse-to-patient ratios across many hospital unit types, and Massachusetts sets one for the intensive care unit only. Every other state requires a staffing committee, a disclosure rule, or nothing. There is no federal nurse-to-patient ratio anywhere in the country.

Q: Is there a federal nurse-to-patient ratio?

No. Federal law and the CMS Conditions of Participation require “adequate numbers” of nurses matched to patient acuity, not a fixed count, under 42 CFR 482.23. A critical access hospital must keep a registered nurse, clinical nurse specialist, or licensed practical nurse on duty whenever it has inpatients under 485.631, which is a coverage rule rather than a ratio.

Q: Do nurse-to-patient ratio laws change?

Yes, which is why any map is a dated snapshot. Oregon’s ratios phase in through mid-2026, so an older claim that a single state had ratios was true a few years ago and is now out of date. Before relying on any state-law statement, check its date against the current statute or the ANA tracker.

Texas and small hospitals

Q: Does Texas require a nurse-to-patient ratio?

No. Texas requires a nurse staffing committee with at least 60 percent direct-care registered nurses and a written, adopted staffing plan under Health and Safety Code 257.004. The plan sets staffing by acuity and unit rather than a statewide ratio, and the hospital must keep records showing the plan was followed on each shift.

Q: How does a hospital without a legal ratio prove it staffs safely?

By documenting to its plan. Where no ratio applies, the staffing committee’s written plan is the standard, so the hospital keeps schedules and staffing records that show each shift met the plan’s coverage and skill mix. A surveyor asks how you met your plan, not whether you hit a number the state never set.
