@Dave Katz and @Bill S.I have thoroughly researched zoning and codes, I and spoken with the city.

Electricians will not risk their reputation/license by leaving anything that’s dangerous behind on a job.For it to be up to code, its important that you have the ungrounded outlets on all circuits that have the knob and tube (the two prong type).  

Today I received a codes violation stating the lower units kitchen was not permitted. 

I was able to locate the code from 2015 that does talk about specs of a rain cap: http://www.seattle.gov/documen...

1% rule In CA works last time in 1994.1% rule is still working in 2022 in certain zip codes in Indiana, Ohio, and Alabama, but even there the median is 0.8 by now with sub 3% rate/25%down.

Do a search on zip code 20151 and contact one of the real estate agents with a listing there(search under 100K).

Although it is currently up to code, he said if the end buyer has an inspection done, the other inspector may recommend replacing it.

You are also obligated to follow the NAR code of ethics.Advertising is state-specific so you would have to check Maryland law.

The valuation approach of options is universal, (check with the ISAB), I bet Canada has a civil code as well.

Union City is also particularly sensitive about basement apartments: there was a program ~10+ years ago where many basement apartments were "legalized" to a third unit, but you'd likely not be able to get a certificate of occupancy today if you had to receive a new one because they don't comply with the current fire code (windows not large enough, no sprinkler system, etc.).
