Source: Boulder County Assessor, public data files: Permits.csv (permits issued by Longmont), read 19 Oct 2026. We count permits issued August 2024 through July 2026; denied and withdrawn permits are left out. The file carries no usable permit status, so it can't say which permits were finished, so no finished share is shown.
Building permits the City of Longmont issues inside city limits, as recorded by the Boulder County Assessor. The City of Boulder and unincorporated Boulder County have their own pages on this site; neither is counted here, and neither are the parts of the Longmont area outside city limits.
Counts are permits, not jobs: one job can need several permits. Nobody paid to be on this page and nobody can. Sources and definitions →
