No federal law requires gyms to have an AED, but more than a dozen states do, and in every state a gym without one can face a negligence claim if a member suffers cardiac arrest on the premises. So the honest answer to whether AEDs are required in gyms is: sometimes by statute, almost always by the standard of care, and increasingly by both.
The Federal Position and the State Patchwork
Federal agencies have declined to mandate AEDs in fitness facilities. OSHA encourages voluntary installation through guidance but has no standard specifically requiring the devices.1Occupational Safety and Health Administration. Automated External Defibrillators (AEDs) The CDC identifies fitness centers as one of the public locations where AED access measurably improves survival from out-of-hospital cardiac arrest, but that recognition stops at recommendation.2Centers for Disease Control and Prevention. Public Access Defibrillation State Law Fact Sheet
What exists instead is a growing patchwork of state statutes. More than a dozen states now require health clubs or fitness centers to keep at least one AED on site, and the list has been expanding steadily over the past two decades, with new states added as recently as 2024.
Whether a particular facility falls under its state’s law often turns on definitions. Some statutes apply only to facilities above a certain membership threshold. Others cover any commercially operated fitness space regardless of size. A small yoga studio and a large chain gym in the same state can wind up with entirely different obligations depending on how the statute draws the line, so the first step for any owner or member trying to figure out the rules is to read the specific definition of “health club” or “fitness facility” in that state’s code.
What Compliance Looks Like in Mandating States
In the states that require an AED, buying the device is only the beginning. Compliance usually involves a cluster of ongoing obligations designed to make sure the AED actually works when someone needs it.
- At least one employee certified in both CPR and AED use must typically be on duty during staffed operating hours. Some states tie the number of trained employees to the number of AED units at the facility.
- The device must be stored somewhere visible and unlocked, within quick reach of staff and members. Locking it in a manager’s office defeats the point and violates most of these laws.
- The facility must maintain the device on the manufacturer’s schedule. Batteries last roughly two to five years, and electrode pads expire every two to four years even if never used. Most modern units run automatic self-checks, but documented manual inspections are usually required as well.
- Several states require a licensed physician to oversee the AED program by authorizing the purchase, reviewing the emergency response protocol, advising on placement, and approving the staff training plan.
- A number of states require the facility to register the AED with local emergency medical services so dispatchers know a device is on site when a 911 call comes in from that address.
Signage obligations show up in many of these statutes too. At minimum, the universal AED sign, a red heart with a white lightning bolt, should be posted at the device. Some states require additional directional signs throughout the facility and basic usage instructions mounted next to the unit.
Unstaffed and 24-Hour Gyms
Key-fob-access gyms with no employee on site create an obvious tension with laws that assume staff will respond. States have taken different approaches, and this is where owners of 24-hour or hybrid facilities need to look closely at their own jurisdiction.
Some states still require the AED in unstaffed facilities but adjust the surrounding rules: prominent signage showing the device’s location, step-by-step instructions posted next to it, and a phone with 911 access available. A few states exempt unstaffed facilities from the employee training requirement entirely, since no employee will be present. Others go the opposite direction and target their AED mandate specifically at gyms that offer non-staffed hours, on the theory that the absence of trained personnel makes a defibrillator more critical, not less.
The American College of Sports Medicine takes the broadest industry position, recommending a public access defibrillation program at every fitness facility, staffed or not, with placement that allows a response time of three to five minutes from collapse to defibrillation. That recommendation carries weight in negligence cases even where no statute applies.
Liability for a Gym With No AED
The absence of a state mandate is not the same as the absence of liability. A gym can face a negligence claim after a cardiac event even in a state with no AED statute, and the claim is built on duty of care: businesses owe their customers a reasonably safe environment, and the question in court becomes whether a reasonable fitness operator should have anticipated the risk of cardiac arrest during strenuous exercise.
Courts answering that question look at industry standards, and the standards are not ambiguous. Both the American Heart Association and the American College of Sports Medicine recommend an AED program at every fitness facility. Research on out-of-hospital cardiac arrests has found survival to hospital discharge of 24% when a bystander applied an AED before paramedics arrived, compared with 9% for CPR alone, and 38% in cases where the AED actually delivered a shock.3National Library of Medicine. Survival After Application of Automatic External Defibrillators Before Arrival of the Emergency Medical System Numbers like those make it hard for a gym to argue that stocking an AED was an unreasonable precaution.
A plaintiff’s attorney in this kind of case will point to the industry consensus, the modest cost of the device, the known cardiac risks of vigorous exercise, and the fact that competing gyms in the same market almost certainly have AEDs. Each of those points makes the missing device look more like a departure from the standard of care.
Liability Waivers Will Not Cover This
Most gyms require members to sign broad liability waivers at sign-up. Those waivers can defeat ordinary negligence claims but generally do not reach gross negligence. A court could reasonably find that skipping a widely recommended, relatively inexpensive life-saving device, in a business whose core activity elevates cardiac risk, crosses from ordinary negligence into something worse. If that happens, the waiver signed at the front desk offers the gym nothing.
Protection for the People Who Use an AED
One reason gym staff and bystanders hesitate to grab an AED is fear of being sued if the outcome is bad. Federal law speaks directly to that fear. Under 42 U.S.C. ยง 238q, any person who uses or attempts to use an AED on someone experiencing a perceived medical emergency is immune from civil liability for resulting harm. The same immunity extends to the business that acquired the device, provided it notified local emergency responders of the AED’s location, maintained and tested the unit properly, and trained the employees reasonably expected to use it.4Office of the Law Revision Counsel. 42 U.S. Code 238q – Liability Regarding Emergency Use of Automated External Defibrillators
Every state also has a Good Samaritan law adding civil immunity for people who render emergency aid in good faith. These protections generally reach gym owners, employees, and fellow members who step in during a cardiac emergency.
The protections have limits. Neither the federal statute nor state Good Samaritan laws shield conduct that amounts to gross negligence, willful misconduct, or reckless indifference. The federal statute also carves out licensed health professionals acting within the scope of their duties and healthcare facilities where medical care is routinely provided. For a gym, the practical rule is simple: keep the AED maintained, train staff, register the device with local EMS, and the law is firmly on your side when someone actually uses it.
The Cost Objection
Cost is the usual reason owners give for not having an AED, and the numbers do not support it. A mid-range unit suitable for a fitness facility runs between $1,500 and $2,000, with entry-level models starting around $1,200. A wall cabinet runs anywhere from $27 to $350. CPR and AED certification for staff typically costs $50 to $150 per person, renewed every two years. Replacement batteries and pads follow the schedules noted above. Set against the cost of defending a wrongful death suit, win or lose, the annual cost of a working AED program is a rounding error.
Modern AEDs are built for untrained bystanders. They give voice-guided instructions, analyze the victim’s heart rhythm automatically, and will not deliver a shock unless one is medically indicated. The worry that an employee might “use it wrong” and injure someone misunderstands how the device works. The real risk, by every measure available, is not having one on the wall when the three-to-five-minute window starts closing.
