§ 78. Repairs. 1. Every multiple dwelling, including its roof or

roofs, and every part thereof and the lot upon which it is situated,

shall be kept in good repair. The owner shall be responsible for

compliance with the provisions of this section; but the tenant also

shall be liable if a violation is caused by his own wilful act,

assistance or negligence or that of any member of his family or

household or his guest. Any such persons who shall wilfully violate or

assist in violating any provision of this section shall also jointly and

severally be subject to the civil penalties provided in section three

hundred four.

2. Whenever, the light, ventilation, or any matter or thing in or

about a multiple dwelling or part thereof, or in or about the lot on

which it is situated, is in the opinion of the department in a condition

or in its effect dangerous to life or health, the department may order

or cause any such light, ventilation, matter or thing to be repaired or

improved or, as provided in section three hundred nine, take such other

action as it may deem necessary to remove such danger to life or health.
