By law, most elevators in the United States must be inspected at least once a year, and some jurisdictions require an inspection every six months. On top of that routine check, the model safety code layers in an annual functional test of the elevator’s safety devices and a full-load test of the emergency braking system every five years. How often elevators need to be inspected by law ultimately depends on the state or city where the building sits, because the binding schedule is set locally rather than federally.
Where the Frequency Actually Comes From
There is no single federal law that dictates inspection frequency for elevators in ordinary commercial buildings, apartments, or offices. The binding schedule comes from the Authority Having Jurisdiction, or AHJ. Depending on where you are, that can be a state department of labor, a city buildings department, or a county code enforcement office. The AHJ writes the rules the building owner has to follow and decides who is authorized to carry the inspections out.
Most jurisdictions build their rules on the same model: the ASME A17.1 Safety Code for Elevators and Escalators, jointly published by ASME and CSA, which serves as the foundation for the design, construction, installation, operation, testing, and inspection of elevators across North America.1ANSI Blog. ASME A17.1-2025 Safety Code for Elevators and Escalators A companion document, ASME A17.2, spells out the procedures inspectors actually follow. Local code adopts a specific edition of A17.1, sometimes with amendments, and which edition governs a particular elevator generally depends on when it was installed or last substantially altered.
Federal rules exist in narrow contexts that do not apply to typical buildings. OSHA requires elevators at marine cargo handling facilities to be thoroughly inspected at least once a year with additional monthly operational checks by designated personnel,2Occupational Safety and Health Administration. 29 CFR 1917.116 Elevators and Escalators and elevators aboard certain passenger vessels must meet ANSI A17.1 as a condition of Coast Guard certification.3eCFR. 46 CFR 120.540 Elevators For a standard office building or apartment complex, though, the schedule lives in state or city code.
The Three Recurring Intervals
In jurisdictions that follow ASME A17.1, an in-service elevator is subject to three layers of ongoing oversight, each on its own clock.
Annual Periodic Inspection
A qualified inspector performs a thorough visual and operational examination at least once per calendar year. Some jurisdictions require this every six months instead. The inspector walks through the physical condition of components, verifies that safety devices work, and confirms the elevator operates within its design parameters. This is the baseline check that most people mean when they say an elevator has been “inspected.”
Category 1 Test — Every Year
The annual Category 1 test goes a step beyond a visual inspection. The inspector triggers each safety device to confirm it activates properly, without subjecting the system to full emergency loads. The governor, for example, which monitors car speed and triggers the safety brake if the elevator overspeeds, is tripped to verify it engages. Category 1 testing runs on the same yearly clock as the periodic inspection.
Category 5 Test — Every Five Years
Every 60 months, traction elevators go through a full-load safety test. The car is loaded to its rated capacity and run at rated speed while the governor is manually tripped, forcing the car safeties to engage and stop the car on the guide rails. It is the most demanding test in the periodic schedule and the one that confirms the emergency braking system can actually stop a fully loaded car in a real overspeed event.
Category 5 testing is physically stressful on the equipment. After the test, inspectors check stopping distance, verify that guide rails and safety jaws are undamaged, and tag the controller and governor with the test date and agency name. Hydraulic elevators follow a different testing protocol, since they rely on pressure-relief valves and check valves rather than mechanical safeties on guide rails.
The One-Time Inspection That Isn’t on the Recurring Schedule
Before a newly installed elevator can carry its first passenger, it goes through an acceptance inspection. The same applies to any existing elevator that has been substantially altered, such as replacing the drive system or upgrading the controls. A qualified inspector witnesses a battery of tests to confirm the installation meets the current code edition, and passing is the prerequisite for the initial operating certificate. Acceptance inspection is a one-time event tied to installation or alteration, not part of the ongoing frequency an owner has to plan around.
Who the Law Allows to Do the Inspection
Elevator inspections are not something a building superintendent can handle. They require a Qualified Elevator Inspector, typically someone who holds a QEI certification issued through NAESA International or the Qualified Elevator Inspector Training Fund after demonstrating experience and passing an assessment on the ASME A17.1 and A17.2 codes.4Qualified Elevator Inspector Training Fund.

In most jurisdictions, the entity performing the periodic inspection has to be independent of the company under contract to maintain that same elevator. The reason is straightforward: the mechanic should not be grading their own homework. Some AHJs use government-employed inspectors, others authorize private third-party agencies, and many use a mix. Which model applies is a local choice.
What the Building Owner Has to Do
The building owner or property manager carries the legal responsibility for keeping the elevator safe and in compliance. That does not stop at hiring a maintenance company. It includes scheduling every required inspection, paying inspection and certificate fees, and making sure the elevator is available and operational on the appointed date.
ASME A17.1 also requires a written Maintenance Control Program for every elevator. The maintenance company usually drafts it, but the owner is responsible for making sure it exists, stays current, and is posted in the machine room where elevator personnel can reach it. The MCP lists every required maintenance task, the interval for each, and the procedures to follow. Intervals are not one-size-fits-all: the code requires them to reflect the equipment’s age, condition, usage, environment, and manufacturer recommendations. A hospital elevator running around the clock needs more frequent attention than a low-rise office car with modest traffic.
Maintenance records must be kept on-site for at least five years, or from the date the current code edition was adopted, whichever is shorter. Wiring diagrams, written test procedures, and evacuation instructions belong in the same file. Inspectors review this documentation during periodic inspections, and gaps raise immediate questions.
Costs recur with the schedule. Owners should budget both for the professional inspection and for the government filing or certificate fees, which vary by elevator type, building height, and jurisdiction.
What Happens If an Inspection Is Skipped or Failed
When an inspector finds code violations, the owner receives a report listing each deficiency and a deadline for correction. Timeframes depend on jurisdiction and severity. Minor violations might carry a 90-day window; conditions that pose an immediate danger to passengers can trigger an order to shut the elevator down on the spot until repairs are complete.
Operating an elevator with uncorrected violations or an expired inspection certificate exposes the owner to escalating consequences. Fines in many jurisdictions accrue on a per-violation, per-day basis, and the totals climb fast. The larger risk is liability. If someone is injured in an elevator that was overdue for inspection or had known uncorrected deficiencies, showing that the owner met their duty of care becomes very difficult. Liability isn’t limited to the owner either: the maintenance company can face claims if an accident traces back to poor maintenance, missed service visits, or a failure to report a known hazard.
How to Tell If an Elevator Is Current
The simplest way to check whether an elevator is on schedule is to look for the posted inspection certificate. Most jurisdictions require it to be displayed inside the cab, usually framed under a transparent cover. The certificate shows the inspection agency, the date of the most recent inspection, and when the certificate expires.
An expired certificate is a red flag. It can mean the inspection is simply overdue, or that the elevator failed its last inspection and repairs are still outstanding. Either way, it points to a compliance gap. Some jurisdictions allow the certificate to be kept in the building manager’s office instead of inside the cab, as long as a notice in the elevator tells riders where to find it. If there is neither a certificate nor a notice, the building likely has a compliance problem worth reporting to the local AHJ.
