Elevator Inspection, Maintenance and Regulation Explained

Anyone who rides an elevator regularly eventually wonders who decides that it is fit to run. The honest answer is a layered one: a published code sets technical requirements, a government body adopts and enforces some version of it, a qualified inspector checks the machine, and a separate mechanic keeps it working between those checks. This page walks through that chain, shows how a few public regulators describe their own programs, and explains why two buildings a few hundred miles apart can follow quite different rules.

It is a general guide, written from public pages. It does not interpret any code for a particular building. For anything specific, the local authority and qualified professionals have the final word.

Who regulates elevators

In the United States there is no single federal elevator inspector. Programs are run by states, and in some places by cities, which adopt a safety code and then decide how to enforce it. New York City's Department of Buildings, the Texas Department of Licensing and Regulation, and the New Jersey Department of Community Affairs are three examples, and each runs its program differently. The United Kingdom takes another route entirely, which we come to below.

What these bodies have in common is a division of labor. The regulator adopts a code and issues or records the paperwork that lets a unit operate. A registered or certified inspector examines the equipment. A licensed or registered mechanic maintains it. The owner of the building sits in the middle and carries the responsibility to see that all three things happen. Texas puts this plainly in its owner guidance: an owner "may not lawfully delegate the responsibility for safely maintaining the building and equipment," according to the Texas Department of Licensing and Regulation FAQ.

How codes and standards are structured

A safety code is a written set of technical requirements, maintained by a standards committee. Governments then adopt it, sometimes with amendments, which is why the code is not itself law until a jurisdiction says so.

The main North American document is ASME A17.1, published jointly in Canada as CSA B44. ASME describes it as "the accepted guide throughout North America" for the design, construction, installation, operation, inspection, testing, maintenance, alteration and repair of elevators, escalators and related conveyances. Notice how wide that list is. The same code that tells a designer how a machine should be built also governs how it is tested and maintained over its life. (For the machine itself, see how elevators and lifts work.)

A companion document speaks to the person doing the checking. ASME A17.2 is a guide for inspection, and ASME's page says it offers "recommended inspection and testing procedures for electric and hydraulic elevators, escalators, and moving walks." The same page notes that the guide also addresses equipment built to A17.1 editions as early as 1955, and cautions that it "may not reflect the latest requirements in the current A17.1" code. That caution tells you something useful: elevators last for decades, so inspectors routinely meet machines built to older editions than the one currently in print.

A third document covers a different family of machines. ASME A18.1 provides guidance for "inclined stairway chairlifts, and inclined and vertical platform lifts," devices meant for the transportation of a mobility-impaired person only. Those machines have their own page on this site, wheelchair and platform lifts.

International contexts: EN 81 and ISO

Outside North America, many countries lean on the European EN 81 family. EN 81-20, issued by the European standards body CEN through its technical committee on lifts, escalators and moving walks (CEN/TC 10), states in its scope that it specifies "the safety rules for permanently installed new passenger or goods passenger lifts," according to a standards catalogue listing. It is aimed at new installations.

That points to the key to the whole subject. Standards are technical. Whether and how they bind anyone is decided by national or local law. ISO publishes lift standards as well, but we did not open an ISO page, so we leave their contents out.

What a periodic inspection and a category test are

An inspection is a visual and functional check of a machine as it currently stands, carried out by someone independent of the maintenance work. A test goes further and operates safety devices on purpose to see whether they perform. Regulators often require both, on different cycles.

New York City shows this clearly. Its Department of Buildings elevator compliance page describes a periodic inspection as an annual visual inspection, and a Category 1 (CAT1) test as an annual no-load safety test. A Category 5 (CAT5) test comes around every five years and checks the elevator at rated load and speed. Category tests are performed and witnessed by approved independent third-party agencies licensed by the department. The page also says the agency doing the periodic inspection cannot be affiliated with the agency that maintains the device.

Texas uses a simpler rhythm. The state's FAQ says "the owner of the elevator or related equipment must obtain an inspection every 12 months," and that the owner is responsible for obtaining a Certificate of Compliance good for one year. Inspectors there register with the department but are not its employees, and the building owner or agent selects one.

The UK calls the equivalent step a thorough examination. The Health and Safety Executive (HSE) describes it as "a systematic and detailed examination of the equipment and safety-critical parts," carried out by a competent person under the Lifting Operations and Lifting Equipment Regulations (LOLER). For lifting equipment used to carry people, the default interval is every 6 months unless a written examination scheme sets something different. HSE adds that the examiner should be sufficiently independent and impartial, and should not be the person who does routine maintenance.

A theme repeats: the person who maintains the machine does not also give it its official check. New York City and the UK's HSE both state that separation. What the check finds is a matter for the people involved, and general pages cannot say what any given inspection will cover. For rider-facing safety features, see elevator, lift and escalator safety.

Inspection, testing, maintenance and repair are different jobs

People use these four words loosely, and regulators do not.

Maintenance is the routine work. The New Jersey Department of Community Affairs, in a bulletin on required maintenance checklists, quotes the A17.1 definition: "a process of routine examination, lubrication, cleaning, and adjustment of parts, components, and/or subsystems for the purpose of ensuring performance in accordance with the applicable Code requirements." Repair and replacement are treated as separate activities in that definition, the bulletin notes. Inspection is the independent look. Testing exercises the safety systems. Repair fixes what has failed or worn out.

The distinction matters because it decides who is allowed to do what. The same bulletin explains that New Jersey stopped having state staff perform routine six-month inspections in 2017, but that "this did not, however, relieve the owners" of the duty to maintain devices under the code. Owners instead keep a checklist of maintenance performed by their maintenance company and produce it for inspectors. That is one jurisdiction's choice, and others differ. The owner-focused side of this is covered in elevator maintenance basics for building owners.

Licensing of mechanics and inspectors

Many jurisdictions license the people, not only the machines. Texas requires anyone who performs installation, alteration, testing, repair or maintenance of an elevator to be registered with the department, and requires inspectors to hold certification under the commission's rules. New Jersey's bulletin says its regulations require that elevator maintenance be carried out by a licensed elevator mechanic, and describes narrow categories of work that a mechanic who is not licensed may do only under a licensed mechanic's supervision.

Licensing details are one of the places where rules diverge most. Some places license by trade, some by company, some both. This guide does not claim or imply any such credential for its publisher; it only reports how public regulators describe their systems. If you need to know who may legally work on a particular machine, the issuing authority is the one to ask.

Why rules differ by place

Several things pull in different directions. Governments adopt different editions of the code, sometimes years apart, and amend them. Inspection cycles are set locally: annual in New York and Texas as described above, six months in the UK for lifts carrying people. Who performs the inspection varies too, from state employees to third-party agencies that the department certifies or approves. Even the paperwork is not uniform, and a posted certificate in one state may look nothing like one in another. We cover that in reading an inspection certificate.

Older installations add another layer. Because machines outlive code editions, a regulator may apply the rules in force at installation, the current rules, or some mix. That is exactly the kind of question a general page cannot settle.

What this means for a curious reader

If you are simply a rider, you do not need to do anything with this. Regulation exists so that you do not have to evaluate the machine yourself. If you are a student, the pattern worth keeping is the chain: code, adopting authority, independent inspector, licensed maintenance, accountable owner. If you own or manage a building, the local issuing authority is the source for what applies to you, and a qualified provider can explain the details. For emergencies, including someone trapped or hurt, call emergency services and use the building's emergency phone; nothing on a general page substitutes for that.

The short version

Codes set the technical rules, governments decide which rules apply, independent inspectors check, licensed mechanics maintain, and owners answer for all of it. Because each place makes its own choices about editions, intervals and paperwork, the local authority and qualified professionals always have the final word.
