This document discusses housing standards and their relationship to public health. It defines housing as including both physical structures and surrounding community services. Standards are proposed for housing sites, setbacks, floors, walls, roofs, rooms, floor area, cubic space, windows, lighting, kitchens, privies, bathing facilities, and water supply. Rural housing standards are also outlined. Poor housing can contribute to respiratory, skin and rat-borne infections as well as accidents and psychological impacts. Overcrowding in particular can promote the spread of infectious diseases. The document proposes indicators for evaluating housing quality related to physical characteristics, economics, and prevention of illness, comfort, and mental health.

the physical structure providing shelter, as well as
the immediate surroundings and the related community services
