Partition question.

[Kelvin Ng]

Hi, I'm new to the real estate business and I have lots to learns. I just recently purchased a 2 family house and I'm thinking about partitioning one of the floors to make 2 two bedrooms apartments. I have done some research and I'm clear on the zoning for the area. My knowledge to this industry is limited but I need expert advise if there are any legal matters or other issue before I approach this project. Thank you in advance.
