- Jobs are distinct permitted sites; a site with several permits counts once.
Permit records show what was permitted, when, and by whom. They do not show workmanship, price fairness, or unpermitted work. Declared values are entered by applicants and are commonly understated. Completion figures reflect the county's closing process and are shown only relative to peers in the same window. Loudoun County and Arlington County disclaim the accuracy of their data; so does this site.
