- 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. Fairfax County disclaims the accuracy of its data; so does this site.
