Is a property really a triplex?

[Damola Adedeji]

I am a new real estate investor interested in my 1st property and ready to buy.

Identified a potential fixer upper that needs a lot of work. It is advertised as 3family(Unit 1 is 3bdr 1bath, Unit 2 is 1bdr 1bath and unit 3 is 1bdr 1bath). Numbers look good.

Visited the property and it is connected to another property(seperated by walls)

How do I verify if it is zoned as multifamily unit? Property is located in NJ

If it is NOT multifamily, what is the process to make it a 3family since I will be doing full scale renovation?

Is it worth going through that exercise for a 1st investment?

Thanks in advance
