Building Department annual reports date from 1894 to 1977. The earliest reports, from 1894 to 1895, are from the Department of Buildings, Bridges, and Wharves. Reports by the steam boiler inspector are included in the annual reports starting in 1920 when that activity became part of the Building Department. Early reports discuss building construction and inspection; safety concerns are a frequent topic in these reports. The 1921 report from the Superintendent of Buildings lists all property under supervision of the Superintendent. Some reports reflect the economic condition of the City in the context of new construction. Other reports put the City within a national perspective. There is different statistical information for different years. Included is information on permits issued, lists of buildings erected, lists of revenue derived from city property, and maintenance cost of department automobiles. Some reports have organizational charts for the department. The 1934 report contains a useful history of legislation relating to building regulations. Reports in the 1950s discuss new legislation relating to construction. Changes in fire and building codes are also reflected in the reports. Reports in the 1960s and 1970s reflect major building projects, such as the Seattle Center and the Model City Program.
