No permanently installed carbon monoxide alarms were found. This is a potential safety hazard. Some states and/or municipalities require CO alarms to be installed for new construction and/or for homes being sold. Recommend installing approved CO alarms outside of each separate sleeping area in the immediate vicinity of the bedrooms on each level and in accordance with the manufacturer's recommendations.

Branch circuit wiring installed in buildings built prior to the mid 1980s is typically rated for a maximum temperature of only 60 degrees Celsius. This includes non-metallic sheathed (Romex) wiring, and both BX and AC metal-clad flexible wiring. Knob and tube wiring, typically installed in homes built prior to 1950, may be rated for even lower maximum temperatures. Newer electric fixtures including lighting and fans typically require wiring rated for 90 degrees Celsius. Connecting newer fixtures to older, 60-degree-rated wiring is a potential fire hazard. Repairs for such conditions may involve replacing the last few feet of wiring to newer fixtures with new 90-degree-rated wire, and installing a junction box to join the old and new wiring.
It is beyond the scope of this inspection to determine if such incompatible components are installed, or to determine the extent to which they're installed. Based on the age of this building, the client should be aware of this safety hazard, both for existing fixtures and when planning to upgrade with newer fixtures. Consult with a qualified electrician for repairs as necessary.
