Sec. 3.3  Sheltered housing facilities.

    (a) Heating, cooling, and temperature. The sheltered part of 
sheltered housing facilities for dogs and cats must be sufficiently 
heated and cooled when necessary to protect the dogs and cats from 
temperature or humidity extremes and to provide for their health and 
well-being. The ambient temperature in the sheltered part of the 
facility must not fall below 50 [deg]F (10 [deg]C) for dogs and cats not 
acclimated to lower temperatures, for those breeds that cannot tolerate 
lower temperatures without stress and discomfort (such as short-haired 
breeds), and for sick, aged, young, or infirm dogs or cats, except as 
approved by the attending veterinarian. Dry bedding, solid resting 
boards, or other methods of conserving body heat must be provided when 
temperatures are below 50 [deg]F (10 [deg]C). The ambient temperature 
must not fall below 45 [deg]F (7.2 [deg]C) for more than 4 consecutive 
hours when dogs or cats are present, and must not rise above 85 [deg]F 
(29.5 [deg]C) for more than 4 consecutive hours when dogs or cats are 
present. The preceding requirements are in addition to, not in place of, 
all other requirements pertaining to climatic conditions in parts 2 and 
3 of this chapter.
    (b) Ventilation. The enclosed or sheltered part of sheltered housing 
facilities for dogs and cats must be sufficiently ventilated when dogs 
or cats are present to provide for their health and well-being, and to 
minimize odors, drafts, ammonia levels, and moisture condensation. 
Ventilation must be provided by windows, doors, vents, fans, or air 
conditioning. Auxiliary ventilation, such as fans, blowers, or air-
conditioning, must be provided when the ambient temperature is 85 [deg]F 
(29.5 [deg]C) or higher.

    (c) Lighting. Sheltered housing facilities for dogs and cats must be 
lighted well enough to permit routine inspection and cleaning of the 
facility, and observation of the dogs and cats. Animal areas must be 
provided a regular diurnal lighting cycle of either natural or 
artificial light. Lighting must be uniformly diffused throughout animal 
facilities and provide sufficient illumination to aid in maintaining 
good housekeeping practices, adequate cleaning, adequate inspection of 
animals, and for the well-being of the animals. Primary enclosures must 
be placed so as to protect the dogs and cats from excessive light.
    (d) Shelter from the elements. Dogs and cats must be provided with 
adequate shelter from the elements at all times to protect their health 
and well-being. The shelter structures must be large enough to allow 
each animal to sit, stand, and lie in a normal manner and to turn about 
freely.
    (e) Surfaces. (1) The following areas in sheltered housing 
facilities must be impervious to moisture:
    (i) Indoor floor areas in contact with the animals;
    (ii) Outdoor floor areas in contact with the animals, when the floor 
areas are not exposed to the direct sun, or are made of a hard material 
such as wire, wood, metal, or concrete; and
    (iii) All walls, boxes, houses, dens, and other surfaces in contact 
with the animals.
    (2) Outside floor areas in contact with the animals and exposed to 
the direct sun may consist of compacted earth, absorbent bedding, sand, 
gravel, or grass.
