If you are only replacing counter tops and/or cabinets and
not altering the physical space by opening or changing walls, a building permit
is not required. Increasing the size of the room, performing structural
modifications (including removing walls), adding or removing a soffit above the
cabinets or removing/replacing drywall will require a building permit. When
applicable, electrical and plumbing permits will be required for any work
performed, and licensed contractors must typically obtain these permits.
