Building permits by US city — monthly volumes, values and big projects
Every permit a city issues is a signal: a new building, a gut renovation, a facade job, a solar install. These pages summarise the official permit registers that US cities publish as open data — how many permits are issued each month, of which type, for how much, and where.
