The measure is derived from approved building permits reported by the Inspectional Services Department (ISD) of the City of Boston. The Boston Area Research Initiative (BARI) has developed and publishes multiple measures from these records to describe patterns of construction and their impacts on land use and value annually and over time in Boston.
