I own a two family home in MA. I currently have tenants on the first floor unit. Off of their bedroom is a ~7ft X 7ft utility room with two small gas boilers and two gas 40 gallon gas water heaters. Is this a safe situation? The utility room is separated from the bedroom by a wood panel door. There is also a duct in the utility room. The home was built in 1970.
I have fitted the bedroom with a Carbon Monoxide detector, but am curious as to whether anyone has or has seen a similar situation? Is this against code? Is it safe?
