What is building permit data?

Building permit data lets you know what work has been done on a building, by who, and when. Derived from building permits from building permit departments, this kind of data provides information on classification of permit types (e.g. roofing), the status of a permit, the cost of the work being done, information on the contractor who undertook the job, and more detailed information on the work undertaken.
