Carroll County, MD Building Safety: Door Locking Hardware (2026)

036, Exterior of Building, is the Livability Code's structural-maintenance subchapter, and its windows-doors-and-frames provisions in subsection (J) end with the door-hardware rule at (J)(5): every exterior door and its hardware must be kept in good condition, and every door lock on a door entering a dwelling unit, whether that door is interior or exterior, has to be in good repair and capable of tightly securing the door. The surrounding paragraphs of (J) set the rest of the door-and-window envelope: doors and windows must be maintained to exclude precipitation and rodents under (J)(1)(a), fit reasonably and be weather-tight under (J)(1)(b), and operable windows must have a locking device capable of preventing entry from outside when locked under (J)(3). 021(E), which requires the owner to keep owner-supplied fixtures and equipment in good working order.
