Description
From January 1, 2027, every NYC building with gas piping has to have natural gas detectors in apartments with gas appliances, and a notice in the common area that tells tenants about them. This is that notice, made to HPD’s format rules so it passes the same way the smoke and carbon monoxide notices do.
What the notice says
That the owner has installed natural gas detectors, where they are placed (3 to 10 feet from each gas appliance and within 12 inches of the ceiling), that the tenant must keep them working and report a missing or failed unit, and the replacement charge the owner may pass on: up to $75 for a unit that detects smoke, carbon monoxide and natural gas. The text appears in English and Spanish on one sign.
Who needs it
Owners of buildings with 3 or more apartments that have gas service, from January 1, 2027. The city has already moved this date once (Local Law 102 of 2025), so check HPD’s detectors page before you print a date on anything. If you prefer one sign for everything, our combined smoke, CO and gas notice carries this text as one block.
Where to post it
In the common area near the mailboxes and the inspection frame, next to the smoke and CO notices, where tenants pass every day.
Read the rules: Natural Gas Detector Notice: The 2027 Rule, Combined Gas, Smoke and CO Notice.

Quick answers
Do I need this before 2027?
No. The requirement starts January 1, 2027 unless the city extends it again. Owners installing detectors early can post it now.
Can it be part of the combined notice?
Yes. HPD’s rule 28 RCNY 12-12.1 allows one combined notice for the gas leak, smoke, CO and natural gas detector notices.
