About liftdue
liftdue is a list of buildings for independent elevator companies. You pick a territory: a 25-mile radius in Texas or one New York City borough.
What the list shows
In Texas it shows the buildings in your territory where TDLR's public file has an elevator more than 60 days past its inspection due date, or due in the next 60 days. In New York City it shows buildings with no current-year test report on file, or an open DOB violation. NYC's test window runs to December 31, so many reports just aren't filed yet.
Texas rows show the owner and site contact as TDLR lists them. NYC rows show the owner from city property records where one is listed. In both, we try to leave out owner names that look like a private person's. Site contacts (in NYC, the managing agent HPD lists) are shown as the agency lists them, and they're often named people. Every row links to its record.
Why 60 days: the inspection report is due at TDLR 30 days after the inspection, but TDLR's late fee only starts 61 days after the inspection. So we wait 60 days before a Texas unit shows as past due. Tex. Health & Safety Code §754.019, TDLR Elevator Program at a Glance, 16 TAC §74.80
It all comes from public files. In Texas that's TDLR's public elevator file. In New York City it's DOB NOW elevator data, with owners from HPD and PLUTO records, all on NYC Open Data. Where the data comes from covers each source and what it does and doesn't prove.
Why not TDLR's free search?
You can use it. It's public, and it's the right tool for one building. It just has no radius or due-date filter. TDLR also posts its whole elevator file as a free download, one row per unit. liftdue places buildings on a map by street address, so your radius works. If TDLR's records show the same elevator inspected under a newer decal, or a building's TDLR archive we've read holds a newer inspection report, we don't list that unit as past due.

What it isn't
liftdue isn't part of any government agency, and it isn't service or dispatch software.
liftdue doesn't contact building owners. We don't tell anyone which companies use it or what they look at; the privacy policy lists the only exceptions.
It says nothing about who maintains an elevator today. TDLR's file and DOB's elevator compliance data have no field for that. So it works both ways: a building you maintain shows up on other companies' lists too, if its public record is past its date. Once the inspection report reaches TDLR and its file shows the new date, the building drops off.
A past date or a missing report in a public file can just be late paperwork, so check the linked record before you act on it. Before you contact an owner, read what the rules say.
How the list is checked
Numbers on liftdue are counts from these records, not estimates. Some addresses can't be placed on a map yet, so a radius count can run low.
Before an update reaches your list, we re-run it on a set of buildings where we already know the right answer and compare random rows with the government's own pages. If a check fails, or a source file is more than a week old, we hold the update. Your list stays on the last update that passed.
On Nov 6, 2026, a separate check, with code that shares nothing with our engine, re-derived 30 random records from the official files; all 30 matched, 1,699 of 1,699 fields. That was a one-time check of that week's data.
