New Jersey state laws require any contractors or subcontractors who sell or make home improvements to be registered with compliance to "Contractors' Registration Act".
However, construction permits are issued, as before, by the municipalities in which contractors are working.
A Contractor must be sure to use a written contract if a project costs more than $500.
Any person who makes improvement project of a home he(she) or his(her) family member owns is not required to registered as contractor.
Before hiring a contractor, make sure that they have a valid license and that their skills are appropriate for the job you are planning.
