Source: Boulder County Community Planning & Permitting building permits on homes in unincorporated Boulder County (the County's Accela permit layer, which stopped taking new applications on May 4, 2026, so the data ends with April 2026; the City of Boulder and the other cities issue their own permits), with issue dates and declared job values from the Boulder County Assessor's permit file. The window is May 2023 through April 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.
