14X-6-602.3 Common corridors and stairways.
Every common corridor and stairway in residential occupancies, other than within a dwelling unit, must be adequately lighted at all times when the building is occupied, either by natural or artificial illumination. Exception: In a Group R-5 occupancy, an adequate lighting system which may be turned on when needed by conveniently located light switches may be provided instead of a full-time lighting system. (Amend Coun. J. 2-19-20, p. 14473, Art. V, § 36)
