Your building's elevator was installed in 2010 under the code in effect at that time. It passed every inspection for 15 years. The equipment is well-maintained. Nothing has failed.
Now you need a controller replacement. Simple upgrade, right? Your elevator company quoted $45,000 for a new controller with modern diagnostics.
What they did not mention: your state adopted ASME A17.1-2019 in 2024. Replacing that controller is classified as a major alteration. Major alterations trigger current code compliance. Current code requires 3D door protection. Your elevator has photocell-only door protection.
Add $25,000 to your quote. Per elevator.
This is not an edge case. This is the reality facing property managers across the 41 jurisdictions that have adopted ASME A17.1-2019. The modernization contract you signed last month may not include compliance costs that will show up as change orders after the state inspector reviews your permit.
This guide explains what changed, which states are affected, what triggers compliance, and what you need to budget before signing anything.
What Is ASME A17.1 and Why Does It Matter?
ASME A17.1/CSA B44 is the Safety Code for Elevators and Escalators. Published by the American Society of Mechanical Engineers, it establishes the baseline safety requirements for elevator construction, maintenance, and inspection across North America. The code is updated on a three-year cycle, with the current edition being A17.1-2019 and A17.1-2022 now available for adoption.
States adopt specific editions of ASME A17.1 into their building codes. When a state "adopts" a code edition, that version becomes the legal standard for all elevator work within that jurisdiction. Some states adopt verbatim. Others add amendments for local conditions such as seismic zones, fire integration requirements, or historical preservation rules.
Here is where the compliance trap opens: states adopt at different times, and the gap between editions can span decades.
California still references ASME A17.1-2004 for elevators contracted after 2008 (and A17.1-1996 for those before). Connecticut adopted A17.1-2019 in 2024. That is a 22-year code gap between two major markets.
The equipment in your California building is legal under a code written when flip phones were standard. The same equipment in Connecticut must meet requirements developed after the smartphone era. Identical equipment, different rules.
When your elevator was installed, it complied with the code in effect at that time. That is "grandfathered" compliance. It means your equipment can continue operating under its original code requirements as long as you maintain it and do not trigger an alteration threshold.
The moment you trigger an alteration threshold, you owe current code compliance. Not the code from 2010. The code your state uses today. If your state adopted ASME 2019, that means 3D door protection, video communication (if applicable), and DLM requirements all become your responsibility.
For more details on how code varies by state, see our elevator state code compliance guide.
Major Changes in ASME A17.1-2019
The 2019 edition introduced several significant requirements that affect existing equipment during alterations. These are the changes driving compliance costs in 2024-2026.
3D Door Protection (Section 2.13.4.2)
Traditional elevator door protection uses a photocell beam across the door opening. If an object breaks the beam, the door reopens. Simple. Effective for objects in the beam path.
The problem: objects not in the beam path. A child's arm at a different height. A briefcase at floor level. Anything outside the single plane of the photocell.
ASME A17.1-2019 requires 3D door detection for new installations and major alterations. 3D systems use multiple sensors to detect objects in three dimensions, creating a detection zone rather than a detection line.
Retrofit costs: $15,000-$30,000 per elevator
This cost includes new sensor hardware, controller programming updates, potential door operator modifications, and state inspector verification. The variation depends on elevator type, door width, and existing infrastructure.
When required: New installations in ASME 2019 states, plus any major alteration (modernization, controller replacement, door operator replacement) to existing equipment in those states.
Video Communication (Section 2.27.3.4)
Elevators with a travel distance of 60 feet or greater must provide both voice AND video communication capability. This is not just intercom functionality. The building's emergency communication system must allow viewing of passengers anywhere in the cab, and emergency responders must have access to the video feed.
Retrofit costs: $5,000-$15,000 per elevator
Cost variation depends on existing telephone/intercom infrastructure, cable runs required, and monitoring system integration.
When required: New installations with 60+ foot rise in ASME 2019 states, plus major alterations to existing equipment meeting the rise threshold.
Door Locking Monitor (DLM)
The Door Locking Monitor electronically verifies that hoistway door locks are engaged before allowing elevator movement. This is a redundant safety system that catches mechanical lock failures before they become passenger hazards.
Critical difference from other requirements: DLM is NOT grandfathered for existing equipment. States adopting ASME A17.1-2019 are setting compliance deadlines that apply to existing elevators regardless of installation date.
Upgrade costs: $10,000-$30,000 per elevator
When required: By deadline set by your state (varies by jurisdiction). Some states are phasing this in through 2027. Check with your state elevator board for specific deadlines.
Car Door Locking Requirements
Enhanced monitoring requirements for car door interlocks affect both hydraulic and traction elevators. This may require controller upgrades to provide the monitoring logic required by the 2019 code.
Upgrade costs: $3,000-$8,000 per elevator
When required: Major alterations in ASME 2019 states.
State Adoption Status (2026)
Not all states move at the same pace. This table shows representative adoption status as of early 2026.
| State | ASME Version | 3D Door Required? | Video Comm (60ft+)? | DLM Deadline? |
|---|---|---|---|---|
| Connecticut | 2019 | Yes | Yes | Active |
| Florida | 2019 | Yes | Yes | Active |
| New Jersey | 2019 | Yes | Yes | Active |
| North Carolina | 2019 | Yes | Yes | Active |
| Alabama | 2019 | Yes | Yes | Active |
| New York City | 2019 + Local | Yes | Yes | Active (with NYC amendments) |
| Texas | 2016 | No | No | TBD |
| California | 2004 | No | No | No |
| Georgia | 2016 | No | No | TBD |
| Illinois | 2016 | No | No | TBD |
| Pennsylvania | 2016 (as of July 2025) | Partial | TBD | TBD |
Important: This table is representative, not exhaustive. Code adoption changes regularly. Always verify current adoption status with your state elevator board before making budget decisions. Our data reflects publicly available information as of March 2026 and may not capture recent amendments or pending legislation.
For states on 2016 or earlier codes, 2019 adoption is coming. When it does, these requirements will apply to any major alteration you perform. If you are planning modernization in Georgia, Illinois, or Texas in the next two to three years, budget for 2019 compliance even if it is not currently required.
What Triggers Code Compliance?
Understanding what triggers compliance is critical for budgeting. Not every repair triggers current code. Not every upgrade is a major alteration.
New Installation
Any new elevator installation complies with the code in effect at the time of permit issuance. No grandfathering. Full 2019 compliance if your state has adopted it.
Modernization
Modernization is a major alteration by definition. When you modernize an elevator (controller, machine, door operators, fixtures), you trigger current code compliance for the entire system.
This is the compliance trap most property managers miss. The modernization quote shows $150,000 for a controller, machine, and door operators. It does not show the $25,000-$50,000 in compliance upgrades required to obtain your permit.

Controller Replacement
Here is where industry practice diverges from code text. ASME A17.1 does not explicitly state that controller replacement triggers full code compliance. However, most state Authorities Having Jurisdiction (AHJs) interpret controller replacement as a major alteration.
The controller is the brain of the elevator. It controls door timing, leveling, safety circuits, and dispatching. When you replace it, you are fundamentally changing how the elevator operates. State inspectors view this as an alteration significant enough to require current code compliance.
Practical impact: If you quote a controller replacement at $45,000, budget an additional $25,000-$50,000 for 3D door protection, video communication (if applicable), and any other 2019 requirements your state enforces.
This is insider knowledge that elevator companies may not volunteer. The salesperson wants to close the controller deal. Compliance costs come later, often as change orders after the permit review.
Door Operator Replacement
Replacing door operators may trigger 3D door protection requirements depending on state interpretation. Some AHJs consider this a major alteration; others classify it as maintenance. Ask your inspector before committing to scope.
Major vs. Minor Repair
Minor repairs, such as replacing a contactor or fixing a relay, do not trigger compliance. You are maintaining existing equipment, not altering it.
Major repairs fall into a gray zone. Replacing the machine, significant hydraulic work, or hoistway modifications may trigger partial or full compliance depending on scope and AHJ interpretation.
When in doubt, ask your state elevator inspector before signing a contract. Getting clarity upfront costs nothing. Discovering compliance requirements after contract signing costs everything.

Cost Impact for Building Owners
Here is the math property managers need to internalize.
Per-Elevator Compliance Costs (ASME 2019 States)
| Upgrade | Cost per Elevator | When Required |
|---|---|---|
| 3D door protection retrofit | $15,000-$30,000 | Modernization, controller replacement |
| Video communication system | $5,000-$15,000 | Rise 60ft+ in ASME 2019 state |
| DLM upgrade | $10,000-$30,000 | By state deadline (varies) |
| Car door interlock upgrade | $3,000-$8,000 | Controller replacement |
Multi-Elevator Building Math
A 4-elevator high-rise in Connecticut needing modernization:
- Base modernization quote: $600,000 ($150K per elevator)
- 3D door protection (4 units x $22,000): $88,000
- Video communication (4 units x $10,000): $40,000
- Total compliance add-on: $128,000
- Actual project cost: $728,000
That is a 21% budget increase the original quote did not mention. This is not hypothetical. This is what happens when property managers sign modernization contracts without understanding compliance triggers.
Some elevator companies include compliance costs in their base quotes. Many do not. The only way to know is to ask specifically: "Does this quote include all ASME A17.1-2019 compliance requirements, including 3D door protection, video communication, and DLM upgrades?"
Get it in writing. If the answer is vague, your change orders are coming.

How to Prepare
Before signing any modernization or major repair contract, work through this checklist.
1. Identify your state's current ASME adoption
Contact your state elevator board or check their website. Confirm whether ASME A17.1-2019 is in effect. If your state is on 2016 or earlier, ask about pending adoption timelines.
2. Document your equipment's installation code
Every elevator has a data plate showing installation date. The code in effect at installation is your "grandfathered" code. Know this number before talking to contractors.
3. Understand what triggers compliance
Ask your state inspector directly: "If I replace the controller, does that trigger full 2019 compliance?" Get the answer in writing if possible. Different inspectors may have different interpretations; knowing yours upfront prevents surprises.
4. Require itemized compliance costs in every quote
Do not accept modernization quotes that say "subject to code requirements." Require line items for 3D door protection, video communication, DLM, and any other applicable requirements. If the vendor cannot itemize, they have not actually scoped the project.
5. Budget 20-40% above base quotes for compliance
Even with itemized quotes, assume additional requirements may surface during permit review or inspection. Building a 20-40% contingency into your capital plan protects against change order shock.
6. Ask the right question before signing
"Does this quote include ALL costs required to obtain a state operating permit after completion, including all ASME A17.1-2019 compliance requirements?"
If the answer is not an unqualified yes, you are signing an incomplete contract.

Red Flags in Modernization Quotes
These warning signs indicate a quote may not include compliance costs.
The quote does not mention code compliance at all
If a modernization quote in an ASME 2019 state does not reference code compliance, 3D door protection, or video communication, the vendor either does not know the requirements or is not including them. Either way, your budget is wrong.
"Subject to code requirements" appears anywhere
This phrase shifts compliance cost risk to you. It means the vendor has not priced compliance into the quote. When the permit reviewer identifies requirements, you pay the change order.
"Excludes building system integration"
Video communication requires connection to building emergency systems. If this is excluded, you are missing $5,000-$15,000 per elevator plus potential building-side infrastructure costs.
"Excludes door protection upgrades"
This is the compliance cost grenade. 3D door protection at $15,000-$30,000 per elevator is the largest single compliance expense in most modernization projects. If it is excluded, your quote is incomplete.
The salesperson does not know your state's ASME version
If the person writing your proposal cannot tell you whether your state runs 2016, 2019, or something else, they have not scoped the compliance requirements. The quote is not real.
Review how these costs affect your bottom line: what elevator repairs cost.
Before You Sign: Use the Contract Scanner
Compliance costs hiding in vague contract language cost property managers millions annually. The proposals that look competitive often exclude the most expensive requirements.
Our Contract Scanner analyzes elevator maintenance and modernization contracts for missing clauses, liability exposures, and compliance gaps. Upload your proposal before signing. Know what is included, what is excluded, and what you will owe in change orders before you commit.
The difference between a $600,000 project and a $728,000 project is one vague clause about "code requirements." Do not sign until you know which number you are actually committing to.

The states that have not yet adopted ASME A17.1-2019 will adopt it eventually. If you are planning any major elevator work in the next three years, budget for 2019 compliance regardless of current state code. The requirement is coming. The only question is whether you budget for it now or pay emergency premiums later.
