Can an owner or contractor prepare construction plans?

The Uniform Construction Code allows a homeowner to preapre his or her own plans for construction, addition, reconstruction, alteration, renovation, or repair on a single-family residence intended to be used exclusively as his/her primary residence.  For all other plans including other residential uses and all non-residential work, the seal and signature of the registered architect or licensed engineer who prepared the plans shall be affixed to each sheet of each copy of the plans submitted.

A contractor, property owner, or tenant cannot prepare plans for rental property, multiple-family dwelling unit, or any non-residential use, including commercial businesses.  Only a New Jerey licensed design professional (architect or engineer) may prepare plans for these uses. 

Exception: For single-family homes or other Class III structures, a New Jersey licensed Electrician or New Jersey Master Plumber may design and submit plans for electrical and plumbing installations.
