Fire Insurance Plans and Atlases
Title
Fire Insurance Plans and Atlases
Description
Fire insurance atlases and plans were detailed urban maps produced from the 1870s to the 1970s to help insurance companies assess fire risk in rapidly growing North American cities. Atlases cover the city as a whole. Plans cover specific neighbourhoods and often have more detail than atlases. At a time when most buildings were wooden and firefighting techniques were limited, even small fires could devastate entire neighborhoods. Companies like the Charles E. Goad Company in Canada and the Sanborn Company in the United States mapped every building in city centers, using colors and symbols to indicate construction materials, building size, occupancy, and potential hazards.
These plans also recorded street widths, property lines, water mains, fire hydrants, and alarm boxes, allowing insurers to evaluate risks efficiently. Although no longer used for insurance, fire insurance plans are now invaluable historical records. Researchers, heritage planners, environmental scientists, and historians use them to study urban development, reconstruct original building forms, trace socio-economic and demographic changes, and identify potential historical land contamination. Large-scale and highly detailed, they bridge the gap between traditional city maps and architectural plans, serving as precursors to modern urban GIS mapping. In Toronto, Goad began producing comprehensive plans in 1880, with atlases for real estate purposes also published from 1884 onward.
