I have a owner of a residential 2 story with a basement row home in Baltimore City Maryland that has contracted me to install a new 100 amp panel and meter because the tenate that lived there before had cut the service wires at the drip loop and then proceeded to steel the old existing meter, panel and cut out some of the wiring in the basement. I have pulled an electrical permit and filled a service application with the utility company to install a new panel and meter. The row home is not a new construction or re-hab. There was some damages to some walls and ceillings, but only patching and painting needed to be done. After walking through the home I noticed that they did not have any smoke detectors. By code, will I need to install them? Any feed back would be appreciated. Thank you.
