Carbon monoxide (CO) inspections are required in Massachusetts for properties that use fossil fuels for heating or other purposes (e.g., natural gas, oil). This is a part of the state’s regulations to protect tenants and homeowners from dangerous levels of carbon monoxide exposure.

The inspection is typically done at the same time as the smoke detector inspection, and there is no additional fee if both inspections are conducted at once. However, the inspection must be completed by the local fire department, not a building inspector. This is because the fire department is authorized to ensure that carbon monoxide detectors are in place and functioning properly.

The carbon monoxide inspection is indeed a prerequisite for selling residential property that burns fossil fuel, but it does not need to be conducted by a building inspector.

Thus, the incorrect statement is that the inspection must be done by a building inspector.
