Elevator Inspection Frequency Requirements

One of the most common questions building owners ask is how often their elevators need to be inspected. The answer depends on the type of inspection, who performs it, and what your state or city requires. ASME A17.1 establishes the national baseline, but local jurisdictions can -- and often do -- impose additional requirements.

Monthly Owner Walkthroughs

While not required by code, monthly walkthroughs by building staff are a best practice recommended by elevator safety organizations and insurance carriers. These are not technical inspections -- they are observational checks that catch obvious problems before they become safety hazards or code violations.

During a monthly walkthrough, building staff should check that the elevator cab is clean and well-lit, all buttons function, doors open and close smoothly without unusual noise, the car levels properly with each floor (no step up or down), the emergency phone connects to a live operator, and the current inspection certificate is displayed and not expired.

Document each walkthrough in a log. This log demonstrates due diligence if an incident occurs and can help your maintenance contractor identify developing issues during their next service visit.

Quarterly Maintenance Checks

Your elevator maintenance contractor should perform routine maintenance visits at least quarterly, though many contracts specify monthly visits. These are not formal inspections -- they are preventive maintenance activities that keep the elevator operating properly and help prevent violations during official inspections.

Quarterly maintenance typically includes lubricating door tracks, adjusting door timing, checking and adjusting leveling systems, cleaning machine room equipment, testing emergency lighting, checking oil levels (hydraulic units), examining ropes for wear (traction units), and running diagnostic checks on the controller.

Your maintenance contractor should provide a written report after each visit documenting what was checked, what was serviced, and any issues that need attention. If they are not providing reports, request them -- you need this documentation for due diligence.

Annual Category 1 Inspection

The annual Category 1 inspection is the formal, code-required inspection defined in ASME A17.1, Section 8.10. This is conducted by a licensed or QEI-certified inspector (not your maintenance contractor, unless they also hold inspection credentials and your jurisdiction allows it). Most states require this inspection every 12 months.

A Category 1 inspection includes a visual examination of all major components, functional testing of safety devices (door interlocks, fire service recall, emergency power), verification of proper operation at all floors, testing of the emergency communication system, and confirmation that the elevator meets current accessibility requirements.

Category 1 inspections do not include full-load testing or testing of the car safety devices under load. Those more intensive tests are reserved for the Category 5 inspection.

5-Year Category 5 Inspection

Every five years, ASME A17.1, Section 8.11 requires a comprehensive Category 5 inspection. This is the most thorough and expensive test your elevator will undergo. It includes everything in the Category 1 test plus full-load and overload testing, car safety device testing under load (for traction elevators), governor tripping speed verification, and buffer testing.

The Category 5 test requires shutting down the elevator for a full day (sometimes longer for older or larger installations) and having your maintenance contractor on site to assist the inspector. This test should be scheduled well in advance and coordinated with building operations to minimize disruption.

Inspection Frequency Summary

State Variations

While ASME A17.1 establishes the baseline, states and cities can impose stricter requirements. Some important variations:

Semi-annual inspections: A few jurisdictions (notably some boroughs in New York City and parts of Massachusetts) require inspections every six months rather than annually.

Witness testing requirements: Some states require that the AHJ witness certain tests rather than accepting third-party inspection reports. This can add scheduling delays.

Category 3 and Category 5 cycles: Some jurisdictions have adopted different cycle lengths for the comprehensive test -- typically three years instead of five. Check with your local AHJ for the exact cycle in your area.

No state program: A handful of states (including Alabama, Wyoming, and parts of others) do not have statewide elevator safety programs. In these states, inspection requirements may be set at the city or county level, or may not exist outside of major metro areas. Even in these locations, building owners should follow ASME standards voluntarily -- insurance carriers expect it, and liability exposure without inspections is significant.
