The ASME A17.1 elevator safety code is the North American standard that governs how elevators, escalators, moving walks, dumbwaiters, and material lifts are designed, built, installed, maintained, and inspected. First published in 1921 and jointly developed with the CSA B44 Technical Committee in Canada, it now runs through the 2025 edition.1The American Society of Mechanical Engineers. A17.1 – Safety Code for Elevators and Escalators On its own the code is voluntary. It becomes enforceable only when a state, province, or municipality adopts a specific edition into law, which is why two buildings a few miles apart can be held to different requirements.
What Equipment the Code Covers
The code applies to any hoisting or lowering mechanism with a car that travels between two or more landings, along with the hoistway, machine room, and control spaces that support it. That pulls in traction and hydraulic passenger elevators, freight elevators, escalators, moving walks, dumbwaiters, and material lifts, whether automatic or manually operated.2ANSI Webstore. ASME A17.1-2019/CSA B44:19 – Safety Code for Elevators and Escalators Freight elevators face specific rules on load capacity and gate construction; passenger cars have tighter limits on door closing force and leveling accuracy. Special-application equipment such as inclined elevators and limited-use/limited-application (LULA) elevators has its own dedicated section.
Home elevators sit inside the code but under stricter physical limits: a car platform no larger than 15 square feet, rated speed capped at 40 feet per minute, and total travel no greater than 50 feet. Safety features still bite. Cars must be fully enclosed except at the entrance, gates need an electric contact that blocks movement unless the gate is within two inches of closed, at least two steel suspension ropes are required, and a telephone or equivalent communication device must sit inside the car.
What the Code Does Not Cover
The exclusion list matters because owners often assume anything that lifts falls under A17.1. It doesn’t. Construction personnel hoists follow ANSI/ASSP A10.4. Platform lifts and stairway chairlifts fall under ASME A18.1. Also outside the code:3ANSI Webstore. ASME A17.1-2019/CSA B44:19 – Safety Code for Elevators and Escalators
- Material hoists on construction sites (ANSI A10.5)
- Manlifts within the scope of ASME A90.1
- Cranes, derricks, and industrial hoists under ASME B30
- Conveyors and related equipment under ASME B20.1
- Amusement devices, stage lifts, and mechanized parking equipment
- Wharf ramps and dock levelers with a rise of 20 inches or less
- Mine elevators in jurisdictions enforcing the National Building Code of Canada
Each excluded category has its own safety code better suited to the equipment’s environment. Hiring an A17.1 inspection firm for equipment that falls under a different standard wastes money and leaves the real compliance question unanswered.
How the Code Becomes Enforceable Law
ASME A17.1 is a published standard, not a self-executing statute. It gains legal force only when a government body adopts it. The most common pathway runs through the International Building Code, which references ASME A17.1/CSA B44 as the governing standard for elevators, escalators, dumbwaiters, and moving walks in Chapter 30.4International Code Council. Chapter 30 Elevators and Conveying Systems When a jurisdiction adopts a particular IBC edition, it simultaneously adopts the referenced edition of A17.1. Some states adopt A17.1 directly through standalone elevator safety legislation.
The enforcement body is called the Authority Having Jurisdiction (AHJ). Depending on the location, that could be a state labor department, a fire marshal’s office, a building department, or a dedicated elevator safety board. The AHJ decides which edition is in effect, issues permits, and dispatches inspectors. A contractor working across multiple jurisdictions has to verify the specific code year enforced in each one, because adoption timelines vary. Penalties for noncompliance come from local law rather than from ASME, and can include fines, permit suspensions, or shutdown orders until violations are corrected.
New Installations Versus Existing Elevators
New installations must comply with whatever edition the AHJ has adopted when the building permit is issued. Existing elevators generally continue to operate under the edition in effect when they were originally installed. This grandfathering keeps owners from facing a mandatory overhaul every time a new edition comes out, which happens roughly every three years.
Alterations are the exception, and the definition of an alteration is where the real money lives. Section 8.7 of the code separates alterations from routine repairs. Replacing a controller, changing the rated speed, or modifying the door operator can trigger a requirement to bring the affected systems up to the currently adopted code. A controller and drive replacement alone typically runs $75,000 to $150,000 on a commercial elevator, and the number climbs when other components have to be upgraded to satisfy modern requirements.
Some retroactive requirements apply to existing equipment even without an alteration. The most common involve firefighters’ emergency service and emergency communications. Owners who budget only for routine maintenance and ignore Part 8’s alteration and retrofit triggers often meet those costs as a surprise during annual inspection.
Firefighters’ Emergency Service
Firefighters’ emergency operation is one of the code’s core life-safety features and a frequent source of retroactive upgrades. It works in two phases.
Phase I, Emergency Recall, sends all elevators to a designated landing when a fire alarm activates or a firefighter turns the recall key switch at the designated floor. Cars traveling toward the recall floor continue nonstop; cars heading the other way reverse at the next available landing. Once parked, doors open and stay open, and hall calls, in-car stops, and smoke-sensitive door reopening devices go inactive.
Phase II, Emergency In-Car Operation, gives a firefighter direct control from inside the car after Phase I has recalled it. The firefighter turns a key switch inside the cab, and the elevator responds only to continuous-pressure buttons. Holding “Open” opens the doors; releasing lets them close. A “Call Cancel” button stops the car at the next landing if conditions change. The design principle is that no automated feature should override the person inside the car during an active fire.
Emergency Communications
Every elevator needs a way for trapped passengers to reach help, but the requirements have expanded well beyond the traditional emergency phone. The 2019 edition added functionality aimed at passengers who are deaf, hard of hearing, or speech-impaired.
One-way video lets authorized personnel see inside the cab during an entrapment. The camera’s field of view must cover the floor to within six inches of any wall or door so that small children are visible. Text-based messaging allows responders to send queries like “Do you need help?” and receive simple replies from passengers who cannot speak. Visual notification indicators display messages such as “Help is on the way” inside the cab. Operable parts of the system must meet accessibility standards, including a reach range of 15 to 48 inches above the floor and minimum legibility dimensions for message characters.
Older buildings may need to retrofit these features depending on which edition the AHJ has adopted, and the AHJ sets the compliance timeline.
Cybersecurity for Connected Elevators
The 2022 edition added Section 8.14, the first time A17.1 addressed cybersecurity. The section applies to any elevator controller or connected device with an enabled internet connection, whether direct or indirect through another networked device.
The requirements focus on three areas. Internet-connected controllers must meet referenced IEC cybersecurity standards, typically shown through process certification documentation. The system must include a way to disable both Remote Interaction Operation (RIO) and internet connectivity entirely, at the individual elevator or group level, with on-site documentation explaining how. If the internet is used to download executable software to controllers, the download process must satisfy the code’s software integrity requirements. In short, the code allows cloud-connected diagnostics, remote monitoring, and over-the-air updates, but requires the ability to cut the connection.
Maintenance, Testing, and Inspection
Every covered piece of equipment must have a written Maintenance Control Program (MCP). This is not a best-practice suggestion. It is a mandatory document that has to be accessible to elevator personnel and available to inspectors. The MCP must set scheduled maintenance intervals, list cleaning and lubrication procedures, and record every maintenance task, examination, adjustment, repair, replacement, and callback with its corrective action. Intervals cannot be uniform across a fleet: the code requires scheduling to account for equipment age, wear, usage, environment, manufacturer’s recommendations, and component quality. Instructions for locating the MCP must appear in or on the controller.
The code adds two levels of periodic testing on top of routine maintenance. Category 1 tests cover basic operational checks, generally performed annually. Category 5 tests are more comprehensive, involving full-load safety tests and buffer tests, and are typically required every five years. Results go into the equipment log and to the AHJ. These tests are independent verification that safety devices still function as designed, separate from preventive maintenance work.
Who Can Inspect
Most jurisdictions require inspectors to hold a Qualified Elevator Inspector (QEI) certification under the ASME QEI-1 standard.5NAESA International. QEI Certification For exams taken after March 1, 2026, the required codebook is ASME QEI-1-2024. Certification requires a high school diploma or GED, five years of supervised elevator trade experience (which can include an 8,000-hour national apprenticeship plus one year of post-apprenticeship work), and a passing score on the National Elevator Industry Education Program mechanics exam or an equivalent.6Qualified Elevator Inspector Training Fund. Become an Inspector Owners hiring third-party inspection firms should confirm QEI certification from an ANAB-accredited organization. An inspection by an unqualified person may not satisfy the AHJ, and the building may not receive its operating certificate even if the equipment itself is fully compliant.
What Compliance Actually Costs
The code itself is a purchased document, and the meaningful expenses come from compliance rather than from the book. Plan review fees for new installations and annual operating certificate fees vary by jurisdiction. Roughly 36 states impose some form of state-level licensing on elevator mechanics or contractors, and those fees vary as well.
The largest costs typically come from alterations that trigger code upgrades. A commercial controller and drive replacement runs roughly $75,000 to $150,000 before any additional required upgrades. Retrofitting emergency communications with video and text capability, adding cybersecurity controls to internet-connected equipment, and upgrading firefighters’ service each carry their own costs that depend on existing infrastructure and the AHJ’s adopted edition. For owners of older buildings, these are foreseeable expenses rather than remote possibilities, and the practical way to avoid surprise orders is to track which edition the AHJ enforces and understand where the line between repair and alteration sits.
