California Drug & Alcohol Rehab Facility Negligence Lawyer

When someone enters a drug or alcohol rehabilitation facility, their family expects staff to watch over, care for, and protect them while they receive treatment. Unfortunately, that does not always happen.

A patient can be seriously injured or die because facility staff failed to recognize a medical emergency, failed to monitor someone during detox, gave the wrong medication, allowed dangerous conditions to exist, or failed to provide the level of supervision the patient’s situation required.

At Bisnar Chase, we represent people who have suffered serious physical injuries and families who have lost loved ones because of alleged negligence at drug and alcohol rehabilitation and treatment facilities.

What Is Rehab Facility Negligence?

Rehab facility negligence occurs when a facility or its employees fail to take reasonable steps to protect a patient or resident from a foreseeable risk of harm, and that failure causes an injury or death. Injuries or deaths at a rehabilitation facility do not, by themselves, establish negligence.

The important questions are:

• What did the facility know about the patient’s condition?
• What should its staff have recognized?
• What monitoring or supervision was appropriate?
• What policies and procedures applied?
• Were those policies followed?
• Was the patient properly evaluated before and during treatment?
• Did staff recognize signs of overdose, withdrawal, or medical deterioration?
• Was emergency medical care requested quickly enough?
• Were medications properly administered and monitored?
• Was the facility properly staffed?
• Did the facility comply with applicable California laws and regulations?
• Did something the facility did—or failed to do—cause the injury or death?

Those are the questions we investigate when evaluating a potential case of rehab negligence.

How We Investigate a Rehab Facility Negligence Case

A facility’s explanation of what happened is only one piece of the investigation. We look at the evidence.

That can include admission records, medical records, medication records, detoxification observation logs, incident reports, staff schedules, policies and procedures, communications, surveillance video, photographs, emergency medical records, autopsy or coroner records, and other documents showing what happened before, during, and after the incident.

We also look at what the facility was required to do. California regulates residential substance-use-disorder treatment facilities through the Department of Health Care Services (DHCS). California regulations address residential treatment services, facility operations, treatment planning, resident care, staffing, and other requirements.

The goal is not simply to prove that something went wrong. The goal is to establish what should have happened, what actually happened, and how the difference caused the injury or death. Call one of our California alcohol rehab negligence lawyers for a free case review.

California Laws and Regulations We Examine

There is no single “rehab negligence law” that determines every case.

Depending on the circumstances, we may examine California’s general negligence laws, wrongful-death and survival laws, health and safety statutes, California Code of Regulations provisions governing treatment facilities, and requirements imposed by DHCS.

California Health and Safety Code provisions governing substance-use-disorder facilities are particularly important because they establish a regulatory framework for licensed facilities. DHCS states that it has the authority to license adult residential alcoholism or drug-abuse recovery and treatment facilities and to certify and monitor certain outpatient alcohol and drug programs.

California’s regulations define residential alcoholism or drug-abuse recovery or treatment facilities as facilities providing 24-hour residential, nonmedical recovery or treatment services. The regulations also address services such as detoxification, counseling, education, and treatment planning.

Depending on the facts, we may also examine California’s general negligence principles and statutes governing wrongful death and related claims.

A violation of a regulation does not automatically mean a facility is legally liable for an injury or death. Our attorneys still have to establish the elements of the particular claim, including causation and damages. But regulatory violations can be important evidence when determining whether a facility failed to provide the required level of care or protection.

Drug Rehab Facility Negligence

Drug rehabilitation patients can face significant risks during detoxification, withdrawal, medication changes, treatment, and recovery. A facility may be responsible for investigating and responding to those risks appropriately.

Potential problems can include:

• Failure to recognize signs of overdose
• Failure to monitor a patient during detoxification
• Failure to conduct required checks
• Failure to respond to changes in a patient’s condition
• Medication errors
• Failure to provide appropriate emergency intervention
• Inadequate staffing
• Inadequate employee training
• Failure to properly evaluate a patient before admission or treatment
• Unsafe physical conditions
• Failure to follow facility policies
• Failure to obtain appropriate medical assistance

The important issue is not simply that a patient suffered a complication. We want to know whether the complication should have been recognized, prevented, or treated differently.

Alcohol Rehab Facility Negligence

Alcohol withdrawal can present serious medical risks, particularly when a person has a history of heavy alcohol use or other medical conditions. A rehabilitation facility should have procedures for identifying patients who may require closer observation or medical attention.

A potential case may involve allegations that staff:

• Failed to recognize dangerous withdrawal symptoms
• Failed to properly monitor a patient
• Failed to respond to seizures or other medical emergencies
• Failed to obtain emergency medical care
• Failed to follow detoxification procedures
• Failed to properly document changes in the patient’s condition
• Failed to administer or monitor medications appropriately
• Failed to provide adequate staffing or supervision

Again, the evidence determines whether a facility’s conduct amounted to negligence. Your rehab facility negligence lawyer will investigate every aspect of your recovery and stay, including how the accident or injury occurred.

Detox Facility Negligence

Detoxification can be one of the most medically sensitive periods of a person’s treatment. That is why we pay close attention to what happened during the hours and days surrounding an injury or death.

DHCS maintains specific forms and records relating to detoxification observation, including vital-sign and physical-check logs.

In an appropriate case, our legal team may examine whether required observations were performed, whether those observations were accurately documented, whether staff recognized warning signs, and whether the patient’s condition required a response that was not provided.

When an Overdose Happens at a Rehab Facility

An overdose does not automatically mean a rehabilitation facility was negligent. But an overdose can raise important questions.

For example:

• Did the facility know the patient had a history of drug use?
• Did staff know what substances the patient had access to?
• Was the patient properly monitored?
• Were medications controlled and documented?
• Did staff recognize signs of intoxication or overdose?
• How long had passed before someone discovered the patient?
• Was naloxone or other emergency intervention available when appropriate?
• Was 911 called promptly?
• Did the facility follow its own emergency procedures?

Those questions can sometimes be answered from records created before anyone anticipated litigation.

Fentanyl and Other Drug-Related Deaths

Fentanyl and other potent drugs create additional questions when a patient dies inside a treatment facility. The issue is not simply whether the patient had a history of substance use.

We want to understand how the substance became involved in the incident, whether facility staff knew or should have known about the risk, whether the patient was appropriately monitored, and how quickly the facility responded once something went wrong.

California requires covered alcohol and other drug programs to report deaths occurring at the program and client injuries requiring emergency medical treatment to DHCS within one working day, followed by a written report within seven calendar days.

Those reports and related investigative records can become important evidence in a wrongful-death investigation.

Failure to Monitor or Supervise a Rehab Patient

Not every patient requires the same level of observation. A patient experiencing withdrawal, showing signs of intoxication, taking certain medications, expressing suicidal thoughts, or experiencing a significant change in condition may present risks that require appropriate attention.

A case may involve allegations that staff failed to:

• Perform required checks
• Recognize warning signs
• Follow an individualized treatment or monitoring plan
• Respond to a patient’s changing condition
• Communicate important information between shifts
• Maintain appropriate staffing
• Escalate a medical concern
• Obtain emergency assistance

Our California detox negligence lawyer examines the patient’s condition and the facility’s records to determine what staff knew and when they knew it.

Failure to Respond to a Medical Emergency

Time can matter enormously when a patient experiences an overdose, seizure, respiratory problem, severe withdrawal, fall, cardiac event, or other medical emergency.

A central question in many cases is:

• When should the facility have realized that this was an emergency?
• We examine the timeline carefully.
• Who last saw the patient?
• When was the patient checked?
• What was observed?
• When did the staff discover that something was wrong?
• What did they do next?
• When was 911 called?
• When did emergency personnel arrive?
• And what happened in between?

A difference of minutes can sometimes become an important issue in determining causation.

Medication Errors at Rehab Facilities

Medication-related problems can occur in different ways.

Potential issues include:

• Giving the wrong medication
• Giving the wrong dose
• Failing to administer a prescribed medication
• Failing to document medication administration
• Improper medication storage
• Failing to recognize a medication-related reaction
• Failing to communicate medication information between staff members

An experienced medication negligence lawyer examines medication records and related documentation rather than assuming that an adverse event was caused by a medication error.

Inadequate Staffing or Training

A rehabilitation facility has responsibilities that cannot simply be delegated to whoever happens to be available.

We may examine:

• Who was working at the time of the incident
• What their responsibilities were
• Whether they were qualified for those responsibilities
• What training did they receive
• Whether the required staffing levels were maintained
• Whether employees were properly supervised
• Whether the facility had policies addressing the situation
• Whether employees followed those policies

California’s regulatory framework includes requirements concerning the operation and management of residential treatment facilities.

Unsafe Conditions at a Rehab Facility

Negligence is not limited to medical or treatment decisions. A patient can also be injured because of unsafe physical conditions.

Depending on the circumstances, we may investigate:

• Falls
• Broken or defective equipment
• Unsafe stairs or walkways
• Inadequate lighting
• Dangerous swimming pools or other recreational areas
• Fire or other safety hazards
• Inadequate security
• Dangerous objects or substances accessible to residents

The legal analysis depends on what caused the injury and who was responsible for the condition.

Rehab Facility Suicide and Failure to Protect a Patient

A suicide or suicide attempt at a rehabilitation facility requires a careful investigation. It is not appropriate to assume that a facility is automatically responsible because a patient died by suicide.

But if the facility knew—or should have known—about a substantial risk and failed to take reasonable steps required under the circumstances, that conduct may warrant investigation.

We examine the patient’s records, communications, assessments, treatment plans, observations, staffing, facility policies, and the timeline leading up to the incident.

The central question is whether the facility’s conduct contributed to a preventable death.

Wrongful Death at a Rehab Facility

Losing a family member during rehabilitation can be devastating, particularly when the family trusted the facility to keep that person safe.

A wrongful-death investigation may involve many of the same questions as an injury case, but the evidence can be even more extensive.

We may investigate:

• The patient’s condition before the incident
• Admission and screening records
• Detoxification records
• Medication records
• Staff observations
• Facility policies
• Staffing records
• Emergency response
• 911 records
• Hospital records
• Autopsy and coroner findings
• Toxicology
• Communications between facility employees
• Prior complaints or regulatory findings involving the facility

California also has specific statutory procedures governing wrongful-death claims. Which claims are available depends on the relationship of the surviving family member to the person who died and the facts of the case.

California’s 2026 Rehab Death-Reporting Law

There is an important new development for families investigating deaths at California substance-use-disorder facilities.

Beginning January 1, 2026, California expanded the information that licensed SUD recovery or treatment facilities must provide to DHCS after a resident dies.

Under AB 1356, facilities must submit relevant information they did not know at the time of the initial report within 30 days of the resident’s death. If DHCS identifies licensing violations during its investigation, the department must issue a written notice of deficiency, and the facility may be required to submit a corrective action plan or verification of correction.

That matters because a death at a rehab facility can now generate a more detailed regulatory record.

When we investigate a death case, we want to know what the facility reported, what DHCS found, and whether the facility complied with applicable requirements.

What California’s State Auditor Found About Rehab Facility Oversight

There is also important recent government evidence showing why regulatory records can matter.

In a 2024 audit of California’s residential drug and alcohol treatment facilities, the California State Auditor reported that DHCS had received nearly 1,800 complaints during fiscal years 2020–21 through 2022–23. More than half involved program complaints, including allegations involving facility conditions and unqualified staff. The audit also found that more than one-third of the 60 complaints it reviewed were substantiated.

The State Auditor identified resident deaths and insufficient detoxification checks among the types of allegations DHCS treats as high priority. The audit also reported that DHCS had suspended or revoked the licenses of seven small treatment facilities during the audit period after identifying serious patterns of violations.

These statistics do not mean that every complaint represents negligence or that every rehab facility is unsafe. They do show why we believe it is important to look beyond the facility’s explanation and examine the regulatory record.

Current Rehab Statistics & Regulatory Facts

A California State Auditor report published in October 2024 found that DHCS recorded nearly 1,800 complaints about drug and alcohol treatment facilities from fiscal years 2020–21 through 2022–23. More than half were program complaints, including allegations involving facility conditions and unqualified staff.

The auditor found that DHCS investigates resident deaths as well as complaints and that death investigations receive priority. During the audit period, the department suspended or revoked the licenses of seven small facilities.

California’s statewide overdose surveillance system reported 11,727 unintentional or undetermined drug-related overdose deaths in California in 2023. That figure is not rehab-facility-specific, so I would use it only as background—not as evidence that those deaths occurred in treatment centers.

Existing California requirements require covered SUD facilities to report a resident death to DHCS by telephone within 1 working day and to submit a written report within 7 calendar days.

DHCS says that all licensed adult alcoholism or drug recovery/treatment facilities must obtain at least one DHCS Level of Care Designation and an ASAM residential Level of Care Certification consistent with the services they provide. This is a condition of licensure.

What Evidence Can Prove Rehab Facility Negligence?

Most cases require multiple documents for proof. Instead, we build the timeline from multiple sources.

Evidence may include:

Facility records

• Admission records
• Screening and assessment records
• Treatment plans
• Progress notes
• Detoxification observation logs
• Medication records
• Incident reports
• Internal communications
• Staffing schedules
• Employee training records
• Facility policies and procedures

Outside records

• 911 recordings
• Police reports
• Fire department records
• Emergency medical records
• Hospital records
• Coroner or medical examiner records
• Autopsy and toxicology results

Regulatory evidence

• DHCS licensing records
• DHCS complaint records
• DHCS investigation reports
• Notices of deficiency
• Corrective action plans
• Prior regulatory findings

DHCS itself states that it investigates complaints against California alcohol and other drug recovery and treatment programs and investigates reported deaths.

How We Build the Case

At Bisnar Chase, we do not want to simply tell a jury that a tragedy occurred. We want to explain why it happened.

That means establishing a clear sequence:

1. What was the patient’s condition?

We determine what the facility knew when the patient arrived and how that condition changed.

2. What risks should the facility have recognized?

We examine the patient’s history, symptoms, medications, treatment status, and other circumstances.

3. What was the facility required to do?

We examine applicable California laws, regulations, licensing requirements, facility policies, and other standards relevant to the case.

4. What did the facility actually do?

We reconstruct the timeline from contemporaneous records and witness testimony.

5. Where did the conduct fail to meet the standard?

We identify the specific act or omission that may constitute negligence.

6. Did that conduct cause the injury or death?

This is critical. A regulatory violation or mistake does not automatically establish that the conduct caused the patient’s injury or death. We have to connect the conduct to the harm.

7. What are the damages?

For an injury case, that can include medical treatment, rehabilitation, lost income, pain and suffering, and other losses, depending on the circumstances. For a wrongful-death case, California law provides specific rules governing recoverable damages and who may bring the claim.

That is how we approach these cases: evidence first, law second, and a clear connection between the facility’s conduct and the harm suffered by the patient or family.

Can You Sue a Drug or Alcohol Rehab Facility for Negligence?

Potentially, yes. But the answer depends on what happened.

A serious injury or death inside a rehabilitation facility does not automatically establish legal liability. We need to determine whether the facility or an individual responsible for the patient’s care owed a duty, failed to act reasonably under the circumstances, and caused legally compensable harm.

The identity of the defendant also matters. The responsible party could potentially include a facility, operator, employee, contractor, healthcare provider, or another entity, depending on the facts.

That is why an investigation should begin with the evidence rather than assumptions about who is responsible.

What If the Facility Says It Was Not Responsible?

That is not unusual. A facility may claim the patient acted independently, the incident was unforeseeable, the patient breached facility rules, or the injury stemmed from a pre-existing medical or substance-use issue.

Those arguments have to be tested against the evidence.

• What did staff know?
• What did the records show?
• What warnings existed?
• What procedures were in place?
• Were those procedures followed?
• Could the emergency have been recognized earlier?
• Could a different response have changed the outcome?

Those are trial questions.

What If the Rehab Facility Were Unlicensed?

This can create a different set of issues. DHCS states that facilities providing 24-hour nonmedical residential alcoholism or drug-abuse recovery or treatment services to adults generally must obtain a valid license, while some sober-living or transitional-housing arrangements are outside DHCS licensing requirements.

The State Auditor has also reported concerns regarding DHCS’s follow-up with certain unlicensed facilities that allegedly provided or advertised services requiring a license.

If an injury occurred at a facility that may have been operating without the required license, we would investigate that circumstance as part of the case.

What Should You Do After an Injury or Death at a Rehab Facility?

If you believe a loved one was seriously injured because of negligence at a rehabilitation facility, preserving evidence can become important.

Consider taking these steps:

1. Obtain available hospital and emergency medical records.
2. Keep all communications with the facility.
3. Preserve photographs, videos, text messages, and other documentation.
4. Write down what the facility told you and when.
5. Obtain the name and contact information of witnesses when possible.
6. Do not assume the facility’s explanation is the complete story.
7. Consider having the matter investigated before important evidence disappears.

If someone died, preserve the death certificate, coroner or medical examiner records, autopsy and toxicology reports, and communications from the facility.

How Long Do You Have to File a Rehab Facility Negligence Lawsuit in California?

The deadline depends on the type of claim and the circumstances.

California generally provides a two-year limitations period for many personal-injury and wrongful-death claims, but there are exceptions and special rules that can change the applicable deadline.

The California Courts specifically caution that statutes of limitations are fact-specific. That is why families should not assume they have two years simply because an injury or death occurred at a private rehabilitation facility.

If you are considering a claim, have an alcohol and drug rehab attorney determine the applicable deadline as soon as possible, based on the specific facts.

Has the Rehab Facility Been Investigated or Disciplined Before?

When we investigate a serious injury or death, we don’t necessarily stop with the incident itself. We may also look at the facility’s regulatory history.

California’s Department of Health Care Services maintains public records concerning certain complaints, compliance actions, suspensions, probationary status, and license revocations. A facility’s regulatory history does not, by itself, prove negligence in a particular case, but it can provide important information about the facility and may identify records that warrant closer examination or indicate a history of negligence. A facility’s history may include records beyond those sitting in its office.

Who Is Responsible When Something Goes Wrong at a Rehab Facility?

Depending on what happened, there may be questions involving:

• The facility
• The facility’s owner/operator
• Employees
• Medical providers
• Contractors
• Treatment providers
• Other entities involved in the patient’s care

California Rehab Facilities with Recent Revocations or Suspensions

You can read the complete list of facilities targeted for suspension and revocation on the DHCS official website.

A regulatory action does not automatically establish negligence in a particular patient’s injury or death. But when investigating a serious injury or wrongful death, a facility’s regulatory history can be an important part of the investigation.

We want to know whether there were previous complaints, inspections, violations, or regulatory actions that could help explain what happened.

Bisnar Chase’s $11 Million Rehab Facility Verdict

Bisnar Chase has experience litigating serious cases involving rehabilitation facilities. In one case, our attorneys obtained an $11 million verdict involving the death of a rehabilitation patient.

The case involved a patient who entered a rehabilitation program and later died after events involving detoxification, supervision, medication, and the facility’s response to the patient’s condition.

The case illustrates why looking only at the final event does not always help us understand these cases.

The investigation has to go back through the patient’s treatment, the facility’s conduct, the applicable standards, and the decisions made by staff along the way.

Why Choose Bisnar Chase?

Frequently Asked Questions About Rehab Facility Negligence

What is a rehab facility negligence case?

It is a claim alleging that a drug or alcohol rehabilitation or treatment facility failed to act reasonably under the circumstances and that its conduct caused a patient’s injury or death.

Can I sue a rehab facility if my family member overdosed there?

Possibly. An overdose alone does not establish negligence. The investigation must determine what the facility knew, what monitoring and emergency procedures applied, what staff did, and whether a failure by the facility caused or contributed to the death.

Can I sue for a death during detox?

Potentially. Detoxification can involve serious medical risks. The case requires an examination of the patient’s condition, the facility’s responsibilities, staff conduct, emergency response, and causation.

Is a rehab facility responsible if a patient dies by suicide?

Not automatically. A case may exist if the facility knew or should have known about a serious risk and failed to take reasonable steps required under the circumstances. The facts and evidence are critical.

Does a DHCS violation prove negligence?

Not necessarily. A regulatory violation may be important evidence, but it does not automatically establish every element of a civil negligence claim. We still have to establish the applicable duty, breach, causation, and damages.

What if the facility were not licensed?

That can raise additional legal and regulatory issues. DHCS requires licensing for certain residential treatment facilities, while some sober-living arrangements fall outside its licensing authority. The specific services the facility was providing matter.

What records should I request?

Medical records, facility records, medication records, detoxification logs, incident reports, communications, emergency records, coroner records, and other documents relating to the patient’s treatment and the incident can all be important.

How much is a rehab negligence case worth?

There is no standard value. The potential value depends on the severity of the injury or death, medical expenses, lost income, the nature of damages permitted under the applicable claim, evidence of negligence, and other case-specific factors.
