New Florida Elevator Code: Is Your Building Compliant? DLM May Be the Quick Fix

Florida Elevator Code Updates: What Building Owners Need to Know

If you own or manage a building with elevators in Florida, recent code changes may affect you. One of the most impactful is the Door Lock Monitoring (DLM) requirement, which comes from ASME A17.3-2020 (Safety Code for Existing Elevators and Escalators), Section 3.10.12, adopted in Florida's elevator rules.

What is Door Lock Monitoring?

Door Lock Monitoring (DLM) is a safety system that continuously verifies elevator doors are properly closed and locked before the car moves. It prevents the elevator from operating if:

A door is not fully closed
The door lock mechanism has failed
There is any gap between the car and landing doors

This technology has prevented countless accidents nationwide and is now required under updated Florida elevator codes for many existing installations.

Why Florida Updated the Code

Elevator door-related incidents remain one of the leading causes of elevator injuries. The new requirements aim to:

Prevent accidents from doors opening unexpectedly
Detect lock failures before they cause incidents
Bring older elevators up to modern safety standards
Reduce liability exposure for building owners

Does Your Building Need DLM?

If your elevator was installed before the current code cycle, it likely needs a DLM retrofit to remain compliant. This is especially true for:

Hydraulic elevators installed before 2017
Older traction systems without modern safety circuits
Buildings that have received code violation notices
Properties undergoing major renovations or sales

The Good News: DLM is a Quick, Affordable Solution

Unlike full elevator modernization, DLM installation is:

Fast — Most installations complete in 1-2 days
Affordable — A fraction of the cost of major upgrades
Non-disruptive — Minimal downtime for your tenants
Effective — Immediately brings your elevator into compliance

For many buildings facing code deadlines, DLM is the smartest first step. It addresses the most critical safety requirement without the expense of a complete overhaul.

Compliance Deadlines Are Real

Florida's DLM requirement took effect August 1, 2025. The state has deferred enforcement of Section 3.10.12 until August 1, 2029 — but the requirement stands, and retrofitting now avoids the end-of-window rush and keeps your equipment ahead of code.

Do not wait for a failed inspection to act.
