§ 59. Bakeries and fat boiling. 1. It shall be unlawful to construct
or maintain a bakery or a place of business where fat is boiled in any
non-fireproof multiple dwelling or upon the lot on which such dwelling
is situated, unless the ceiling, side walls and all exposed iron or
wooden beams, girders and columns within the said bakery or business
place where fat is boiled, are covered with fireproof materials.

2. There shall be no door, window, dumbwaiter shaft or other opening
between such a bakery or business place where fat is boiled and any
other part of the dwelling, except that:

a. There may be access to the public parts of the dwelling from any
bakery maintained therein if the product of such bakery is consumed
exclusively within such dwelling.

b. In a fireproof hotel where a retail bakery is maintained therein,
there may be access to the public parts of the hotel, provided the door
openings leading thereto from such bakery and the door assemblies are
fireproof with the doors self-closing, and provided the public parts of
such bakery premises are protected by one or more sprinkler heads.

c. In bakeries in which no fat is boiled and on the premises of which
there is no apparatus for fat boiling, a dumbwaiter communicating
between the place where the baking is done and a bakery store above may
be maintained if entirely enclosed in a brick shaft with walls eight
inches or more in thickness, without any openings whatever except one
door opening into the bakeshop and one into the bakery store. Every such
opening shall be provided with a fireproof door and assembly so arranged
that when one door is open, the other is entirely closed.

3. Every part of a bakery, its plumbing, and the yards and open spaces
adjoining shall be kept in good repair, in sanitary condition and free
from rodents and vermin.
