Full Breakdown

1, adopted January 26, 2010, requires a carbon monoxide alarm adjacent to any bedroom in every rental dwelling containing a fuel-burning appliance, with additional alarms wherever the Code Enforcement Official deems necessary. Each alarm must carry a nationally recognized testing-laboratory label and meet UL 2034 or an equivalent standard. As part of the rental permit application or renewal, the owner must file a Town of Islip carbon monoxide detector certificate of installation, or, if not submitting to a physical inspection, a signed affidavit attesting to installation, and give the tenant a copy of that certificate or affidavit.

It is unlawful to render an installed alarm inoperable by breaking it, painting over it, taping over it, disabling it, or pulling the battery: ordinary battery replacement is exempted. Owners must replace any alarm reported stolen, missing, or disabled within five days of notice from the occupant, and occupants must test, maintain, and replace batteries at least every six months and must notify the owner in writing if an alarm is compromised. Compliance is checked at permit issuance and renewal under § 68-653, and the Code Enforcement Official may request an inspection at his discretion.

Violations & Fines

Failure to install or maintain the required carbon monoxide alarms, or refusal to procure/renew a rental occupancy permit, is a violation of Article XLIX under § 68-666: a first offense carries a fine of $750 to $2,500 and/or up to 15 days imprisonment; a second conviction within five years brings a fine of $2,500 to $5,000; a third or later offense within five years is prosecuted as an unclassified misdemeanor with a fine of $5,000 to $10,000 and/or up to one year of incarceration.

Frequently Asked Questions

Do all Islip rentals need carbon monoxide alarms?
Only rental dwellings with a fuel-burning appliance or equipment, per Town Code § 68-653.1B(1). The alarm must be installed adjacent to any bedroom in the unit and kept in good working condition, with battery backup if electrically powered.
Can a smoke detector double as the CO alarm in Islip?
Yes. Section 68-653.1B(1) allows a carbon monoxide alarm to be combined with a smoke-detecting device that complies with the New York State Uniform Fire Prevention and Building Code, rather than requiring two separate devices.
What happens if a tenant disables the CO alarm?
Rendering an installed alarm inoperable, by breaking it, painting over it, taping it, removing the battery, or any similar method, is prohibited under § 68-653.1B(4), and the owner must replace it within five days of learning it's compromised.
Who enforces Islip's CO alarm requirement?
The Town of Islip Code Enforcement Official, who reviews the installation certificate or affidavit at rental permit application and renewal under § 68-653.1C, and may inspect the dwelling at his discretion.
