T
he New York Apartment Association (NYAA) has been fielding numerous calls about Local Law 157, which requires gas detectors in apartments with gas appliances by May 1, 2025. The law's landlord members are concerned that the deadline is too soon, as they need to order UL-certified detectors, and only one model, DeNova Detect, meets this criterion and is also battery-powered. A NYAA spokesperson suggests that if orders are placed early, compliance with the deadline will be manageable, but waiting until April may lead to supply chain issues.

    Local Law 157 applies to multiple dwellings, one- and two-family homes occupied by non-owners, and Class B dwellings like hotels. With over 2.3 million rental units in New York City, nearly 90% of residents use natural gas at home. Landlords and property owners may face significant costs as they try to order millions of DeNova devices, priced at $91.79 each.

    DeNova's 10-year detectors were sold out on Tuesday but appeared to be back in stock the following day. Another company, Pepco, offers a similar product with monitoring, warning owners to "avoid price hikes and detector shortages." The NYAA advises against using plug-in models due to installation requirements and potential tampering by tenants.

    NYAA head Kenny Burgos expressed concerns that the law will lead to increased rents and expenses for older, rent-stabilized buildings in outer boroughs. He hopes the City Council understands the potential impact on these properties.
