How Often Do Elevators Need to Be Inspected?

Inspection Frequency by Type

Annual Inspection: What Most States Require

The annual routine inspection is the cornerstone of elevator compliance in the United States. In most states, a QEI or state-licensed elevator inspector must examine every commercial elevator at least once per calendar year. The inspection covers the full system: machine room equipment, controller, wiring, hoistway, car top, pit, safety devices, door systems, and emergency communications.

The ASME A17.1 code also requires a Category 1 periodic test to be performed concurrently with the annual inspection. This is a no-load test of the elevator's safety devices -- the governor, safety gear, and overspeed system are tested without a full load in the car. The Category 1 test requires the maintenance contractor to be present alongside the inspector because the elevator's safety systems must be manually tripped and reset.

California's Biennial Cycle

California is the only state that operates on a 2-year inspection cycle rather than annual. The California Division of Occupational Safety and Health (DOSH) administers the program. Despite the longer interval, California's inspection is more comprehensive than many states' annual inspections, covering all ASME A17.1 and A17.2 requirements in a single visit.

In practice, California's biennial cycle has created a significant inspection backlog. Many elevators go well beyond the 2-year interval before receiving their scheduled inspection. Building owners in California should not assume that the absence of a recent inspection means they are in compliance -- the state may simply be behind schedule. If you have not been inspected in more than 30 months, contact DOSH to request scheduling.

5-Year Full-Load Safety Test

Every 5 years, ASME A17.1 requires a Category 5 periodic test -- a full-load test of the elevator's safety systems. This is the most rigorous test an elevator undergoes during its operating life. The elevator car is loaded to its full rated capacity (or uses calibrated test weights), and the safety gear, governor, and buffers are tested at full speed and full load to verify they can stop and hold the car in an emergency.

The Category 5 test is expensive ($1,500 to $4,000 per unit) because it requires significant preparation: test weights must be transported to the site, the elevator is out of service for a full day, and the maintenance contractor must be present throughout the test. The test also carries a small risk of damage to safety components, which may need replacement afterward. Despite the cost, this test is non-negotiable -- it verifies that your elevator can actually save lives in a worst-case scenario.

Recommended: Quarterly Maintenance Checks

While most states only mandate an annual inspection, industry best practice is to perform quarterly preventive maintenance on every elevator. These quarterly visits -- separate from the monthly routine maintenance visits in your contract -- involve a more thorough evaluation of wear items, door timing, leveling accuracy, ride quality, and electrical connections.

Many full-service maintenance contracts include quarterly deep checks as part of their standard service. If your contract does not include them, add a quarterly walk-through addendum. The cost is minimal compared to the expense of failed inspections and emergency repairs. Buildings that perform diligent quarterly maintenance have significantly fewer violations at annual inspection time.

Monthly Owner Checks

Building owners and property managers should perform a basic visual and operational check of each elevator monthly. This is not a technical inspection -- it is a common-sense walkthrough that catches obvious problems before they become violations or safety hazards. Here is what to check:

• Ride the elevator: Does it level properly at each floor? Any unusual vibration or noise?
• Check door operation: Do doors open and close smoothly? Do they reverse when obstructed?
• Test the emergency phone: Pick up the phone in the cab and confirm it connects to the monitoring service.
• Check cab lighting: All lights functioning, including emergency battery backup lighting.
• Verify the inspection certificate is current and posted in the cab.
• Check the machine room (if accessible): Look for oil leaks, unusual heat, water intrusion, or unauthorized storage.
• Note any tenant complaints about the elevator and report them to your maintenance contractor.

Document these monthly checks in a log. This record demonstrates due diligence to your inspector, your insurance carrier, and -- if it ever comes to it -- to a court.
