There are provisions in the Building Code for construction of simple one-story buildings without the assistance of plans designed by an architect or engineer.
Homeowners can obtain permits and undertake construction themselves once plans are approved by the City however it is advisable for homeowners to work with a licensed contractor during the construction phase of the project.
Any work exceeding $500 in labor and materials is required to be done by a licensed contractor unless solely done by the homeowner.
Always hire a licensed contractor and request his/her license number. You can contact various State agencies to obtain information:
