Concord sneaky duiplex

[Braeden Warg]

I've come across a property with a basement which i can turn into a separate unit. There's  plenty of parking however when my relator reached out to concord zoning they said it isn't able to be turned into a duplex " which to me means one address instead of two and I cant have separate water and electricity to the units". My relator said we shouldn't go forward because if the city find out we turned it into a duplex the county can take some type of action on us "not sure what that means" "Also i feel like my relator has a legal obligation to tell me not to go through with this because if he said do it anyway i could possible seek legal action on him (ps I wouldn't)".. However through my research i keep coming across this term sneaky duplex where people turn there basements into a unit or block off part of there house to turn into a separate unit. my plan is to use the basement for traveling nurses because you would already have the water and power turned on for them "house is 5 minutes away from the hospital", live in the upstairs for a year and possible house hack one of the rooms. If I can't do this the house loses money big time like 800-1200 a month. Let me know your thoughts and opinions if you have a better route for a first time home buyer let me know.
