Source: City of Saint Paul building and trade permits (the City's old approved-permits file up to June 2025, and the City's PAULIE permit system since September 2025), with the contractor named on each permit. The window is October 2023 through September 2026; a permit filed after that isn't here yet.
Usual is the middle permit: half were filed for less, half for more. Only permits with a filed value count; a value of $0 or none is left out.
The spread is approximate: we keep seven points of each firm's own range of filed values, not every permit, and pool them.
