Records added, edited or removed in Denton County between consecutive exports, August 9, 2026 to August 19, 2026. A column of zero means the roster did not move here that day. The first archive has no column: there is nothing before it to compare against.
Counts are licences whose roster address names that city. About half the
roster leaves the city blank, so these add up to less than the county
total above.
How to read these numbers
A licence is counted here when its roster address is in Denton County.
That is a mailing address, not a service area: plumbing companies work a metro
rather than a county line, so a company one county over may well cover you.
The county is simply the unit the roster records reliably.
Licensees whose address is outside Texas are not counted in any county
on this site. The roster records their home county too, which would otherwise
put places like Los Angeles and Du Page in a list of Texas counties.
