Legal Question in Real Estate Law in New Jersey

Re: Legal Bedroom

There is no universal State law, except for building code requirements, as whether or not you are permitted to have another bedroom depends upon each municipality's local Ordinances on what may be permitted; e.g., does adding a bedroom convert a legal one-family residence into an illegal multi-family residence. If all you are doing is adding a new bedroom (for instance, you have another child), this may be permitted, but you need to know many zoning requirements on how to go about it. I suggest talking to your local zoning officer and building department official to see what if what you intend to do is permitted, and what is required.
