Condos and Townhouses are treated as Commercial Properties for purposes of permitting any work inside a unit.
There are no dollar amounts that trigger the requirement for permitting. All Condos and Townhouse plans are to be prepared by an Architect and must show Architect review, signature, and stamp. The check list for condos and townhouses is more intense. Just doing any alteration, remodeling, plumbing, electrical, or other work within a condominium or townhouse requires the owner to secure an approved building permit BEFORE work is performed.
