I need advise because I'm a first time home buyer and don't know to much about the laws of owing a multi family home.

You likely have a few issues here. First of all you cannot do construction without a permit. Further, in anything but a single-family home, you must use license contractor for certain upgrades like electrical and plumbing.

Finally, you have to make sure that your house is properly zoned as a three Family Residence. You may have to go before the local zoning board if this is not the case.

You should seek experienced land use and real estate attorney
