Carbon Monoxide Detectors Now Required
Carbon monoxide detectors are now mandatory in most homes in New York State. A new law went into effect on February 22, 2010 requiring the devices in any residential building which has a carbon monoxide producing appliance such as a gas or oil operated furnace, stove or hot water heater and any home with an attached garage. Homes with only electric furnaces and stoves do not need the monitors. The Town of Brookhaven does enforce the requirement. The new law has been dubbed Amanda's law, in memory of a Western New York girl who died from carbon monoxide poisoning. For more information contact the Town of Brookhaven Building Division or go to the following NYS web site.

The property owner is ultimately responsible for complying with the building code and codes of The Town of Brookhaven.

Penalties for not obtaining a Building Permit are triple the Permit Fees for each permit required. In some cases, other penalties may result.
