Is ASME A17.1 the law in Texas?

It is enforceable in Texas because the commission adopts it by rule under Health and Safety Code §754.014. The legal duty an owner carries comes from the statute; A17.1 supplies the technical requirements the statute points at.

Does my old elevator have to be brought up to the current code?

Not wholesale. Equipment complies with the A17.1 edition in effect when it was installed, plus the A17.3 minimums that apply to existing installations. Alterations, however, are judged against the code in force at the time of the work.

What counts as an alteration rather than maintenance?

Replacement in kind and ordinary maintenance are not alterations; changes to the equipment's design or function generally are. Controller replacement, door operator changes, and drive changes are typically alteration work with code review attached.

Where can I read A17.1?

ASME publishes and sells the code. Owners rarely need the full text — what matters operationally is which edition applies to your equipment and what your inspector cites, both of which your contractor can walk you through.

Why do door items appear on every inspection report?

Because doors are the most heavily used mechanical subsystem in the building and the code covers them in detail — interlocks, restrictors, and reopening devices all carry requirements. Door equipment also generates the largest share of service callbacks on any platform.

ASME A17.1, Explained for Texas Building Owners

The short answer

ASME A17.1 is the Safety Code for Elevators and Escalators — the North American standard governing how elevators are designed, installed, altered, tested, and maintained. Texas adopts it by rule: Health and Safety Code §754.014 directs the commission to adopt standards, and the adopted framework is built on A17.1 together with A17.3 for existing installations. In practice, your elevator complies with the A17.1 edition in effect when it was installed, and any alteration is judged against the standard in force at the time of the work.

A17.1 is the document behind most of what appears on an elevator inspection report. Owners rarely read it, but every deficiency line traces back to a requirement in it or in the companion code for existing equipment.

This page explains what A17.1 covers, how Texas adopts it, what the edition rule means for equipment of different ages, and why it drives modernization scope.

What is ASME A17.1?

ASME A17.1 is the Safety Code for Elevators and Escalators, published by the American Society of Mechanical Engineers and harmonized with CSA B44 in Canada. It sets the technical requirements for new installations and for alterations to existing equipment, and it prescribes the periodic tests that verify safety devices still work.

It is a consensus safety code, not a law in itself. It becomes enforceable in Texas because the state adopts it by rule — which is why the operative citation for an owner is the Texas statute, with A17.1 named inside the adopted standards.

ASME A17.1: Safety Code for Elevators and Escalators — the design, installation, alteration, and testing standard for new work and alterations.
ASME A17.3: Safety Code for Existing Elevators and Escalators — minimum safety requirements applied to equipment already in service.
Alteration: A change to existing equipment beyond ordinary maintenance or replacement in kind. Alterations are evaluated against the code in force when the work is done.

How does Texas adopt ASME A17.1?

Texas adopts it through commission rulemaking under Health and Safety Code §754.014, which is the statute's standards section. The adopted framework covers ASME A17.1 and A17.3 for elevators and escalators, ASME A18.1 for platform lifts and stairway chairlifts, and ASCE 21 for automated people movers.

The statute also constrains alterations: work on existing equipment may not leave the unit less safe than the chapter requires at the time of the work. That single sentence is why a controller replacement often pulls other code items into scope.

The standards Texas adopts, and what each covers
Standard	Applies to	Owner-facing effect
ASME A17.1	New installations and alterations to elevators and escalators	Sets what new and altered equipment must meet
ASME A17.3	Existing installations, regardless of age	Existing equipment is not frozen at its installation-era requirements
ASME A18.1	Platform lifts and stairway chairlifts	The code path for accessibility equipment short of a full elevator
ASCE 21	Automated people mover standards	Applies to transit-type conveyances rather than building elevators

Which edition of A17.1 applies to my elevator?

Equipment complies with the A17.1 edition in effect on the date it was installed, and alterations are judged against the edition in force when the alteration is performed. A17.3 then applies to the unit as an existing installation on top of that, regardless of how old it is.

The practical reading for an owner: a 1985 elevator is not required to be a 2026 elevator, but it is also not exempt from everything written after 1985. And the moment you alter it, the altered work meets today's requirements.

New installation: A17.1 edition in effect at installationAs adopted by commission rule — §754.014.
Existing installation: A17.3 minimums applyRegardless of installation date.
Alteration: Code in force at the time of the workThe work may not leave the unit less safe than the chapter requires.

Where does A17.1 show up on an inspection report?

Nearly everywhere, but most visibly in door equipment, safety devices, and required periodic testing. Interlocks, restrictors, and reopening devices sit squarely inside the code, which is why door items appear on reports for equipment of every age and every manufacturer.

Landing door interlocks and car door restrictors — locking and closing requirements
Door reopening devices — the detector systems that keep doors off passengers
Car safeties and governor — the devices that stop an overspeeding car, verified by periodic test
Brake and machine requirements — condition, adjustment, and test intervals
Firefighters' emergency operation — recall and in-car modes
Machine room and hoistway conditions — access, lighting, clearances, and guarding
Markings — capacity and loading class posted in the car

Periodic testing is the part owners feel most, because tests are scheduled by category and witnessed. Missing a test cycle turns a maintenance question into an inspection finding.

How does A17.1 affect modernization scope and cost?

It sets a floor that scope has to clear. Because an alteration is judged against the current code and may not leave the equipment less safe than the chapter requires, code-driven items enter the project whether or not they were on the owner's wish list.

The right way to handle that is a code review during scoping, so required items appear in the proposal rather than as change orders after demolition. A proposal that is silent on code-driven scope is not cheaper; it is less complete.

Prime Elevator Corp runs that code review during scoping and performs alterations under TDLR Elevator Contractor License #20478, with the required safety tests completed before equipment returns to service.
