What the Miami-Dade data covers
The feed is Miami-Dade County's permit system. About four in five permits are for unincorporated Miami-Dade; the rest span more than 30 municipalities, including the City of Miami, Coral Gables, Hialeah and Doral. Cities with their own building departments, such as Miami Beach, route only some permits through the county, so their coverage is partial. Miami-Dade issues a separate permit for each trade on a job, so these are permits, and one project can account for several of them.
