Permits and licensing overview

Certain trades additionally require state licensure or city registration (for example, home-improvement contractors register with the Department of Consumer and Worker Protection). Permit applications are submitted through DOB NOW or other official DOB systems.[1]

- Owners or agents who must file plans or hire licensed professionals to obtain DOB approval for permitted work.
