Two: natural gas detectors in every dwelling unit — probably

Local Law 102 of 2025 requires an approved natural gas detector in every dwelling unit. The Council passed it June 30, 2025; it was returned unsigned by the Mayor on July 31, 2025; and it takes effect immediately. The operative date, from the amended Housing Maintenance Code § 27-2045(b)(1)(c):²

“On or before January 1, 2027, provide and install one or more approved and operational natural gas detecting devices in accordance with [section 908.10] section 908.13 of the New York city building code or section [28-315.2.3 of the code] 28-315.2.4, as applicable, or, in the alternative for class B multiple dwellings, provide and install a line-operated zoned natural gas detecting system with central annunciation and central office tie-in for all public corridors and public spaces…”

And the parallel amendment to Administrative Code § 28-315.2.4: “Natural gas alarms. [Natural] On or before January 1, 2027, natural gas alarms shall be provided and installed in accordance with section [908.10] 908.13 of the New York city building code…”

For a New York City condominium or cooperative that is a device in every unit — a procurement and access exercise across the whole building, not a common-area installation.

But the date may have moved, and we cannot tell you whether it did

The same local law added § 28-315.2.4.1, and it is the reason committing the money now is premature:

“Market availability. No later than July 1, 2026, the commissioner shall submit to the mayor and the speaker of the council a determination of the market availability of battery-powered natural gas alarms. Such determination shall indicate whether the department has identified 4 or more distinct manufacturers of battery-powered natural gas alarms that comply with the requirements of section 908.13. If such determination indicates less than 4 such manufacturers, the commissioner shall by rule extend the date by which such alarms must be installed…”

That determination was due July 1, 2026 — two and a half months ago. We could not find it, and we could not establish whether DOB extended January 1, 2027.

So this is a one-call question, and it is worth making the call before signing a purchase order for several hundred detectors: did the Commissioner find four manufacturers, and is January 1, 2027 still the date? We are not publishing January 1, 2027 as settled, and only that call would settle it.

Two elevator corrections worth carrying, because the vendor literature is wrong

Door lock monitoring is not a 2027 deadline and it is not Local Law 126 of 2021. DOB's own industry notice: “Effective January 1, 2020 all automatic passenger and freight elevators must be in compliance with the retroactive requirements found in Appendix K Chapter K3 Section 3.10.12 of the New York City Building Code.” That deadline passed six years ago, and enforcement continues: “The Department will issue OATH summonses to building owners for elevator devices that are not in compliance with DLM requirements after the January 1, 2020 deadline. These devices will be subject to follow-up inspections and additional violations if they remain non-compliant.”³

A board whose Category 1 filing has ever come back with a door-lock-monitoring defect is carrying an open 2020 obligation, not a future one.

And Local Law 126 of 2021 is not a single-subject law. It reaches parapets, parking structures and elevator periodic inspections, among other things, and DOB describes it as bringing the codes up to date with the 2015 editions of the international building, mechanical, fuel gas and plumbing codes, effective November 7, 2022. Treating “Local Law 126 of 2021” as one requirement — which the vendor literature routinely does — produces confident statements that are simply about the wrong provision.

The elevator periodic inspection rules and their calendar dates

From DOB's industry notice on periodic inspections, which is the Local Law 126 provision that does reach elevators: owners “are responsible for the required periodic elevator inspections listed in Table N1 of ASME A17.1, as modified by Chapter K1 of Appendix K” and the inspection “must be performed by an approved elevator agency on behalf of the owner.” The change that caught boards out: “Inspections will no longer be performed by Private Elevator Agency Directors/Inspectors on behalf of the Department of Buildings.”⁴

The timing rules: inspections “must be performed between January 1 and December 31 of each year, at least 90 days from the date of any Category 1 testing or previous periodic inspection”; and the inspecting agency “cannot be affiliated with the agency performing the maintenance.”

Then three deadlines that run in series and are easy to miss: the inspection report to DOB within 14 days of the inspection; correction of identified defects within 90 days of the inspection; and the Affirmation of Correction to DOB within 14 days of the corrections being made.

What a board faces in the next fortnight

Ask your elevator agency one question in writing: do we have traction elevators with single-plunger brakes, and if so what is the scope, the cost and the filing timeline? The answer is either “no, they are hydraulic” — in which case this is over — or it is a capital project that needs a permit before January 1.

Ask DOB or your consultant whether the gas-detector date moved before committing to a bulk purchase.

And check the sequencing against everything else. A board facing a facade cycle, an emissions filing, a gas-piping certification and now an elevator brake alteration is facing a capital calendar, not a series of unrelated tickets. There is one piece of genuinely good news in that: the parking-structure rule expressly permits synchronising a garage inspection with the building's facade cycle, which lets a board hire one engineering team for both.
