The manual presents material designed to acquaint housing inspectors and their supervisors with the origin of public concern about housing problems; the past, present, and new approaches to housing code administration; the expanded role of the inspection function in the neighborhood improvement effort; and the general nature of their role and responsibilities. The first chapter, Trends in Housing, deals with all aspects except for role and responsibilities. That aspect is developed through the succeeding six chapters as individual elements of housing inspection are considered in detail: the housing code, health and sanitary elements, building aspects, plumbing elements, heating and environmental control, and electrical aspects. The manual contains numerous illustrations depicting materials, equipment, and assembly. Terms and procedures are defined and explained. (AG)
