OFFICIAL LOCAL GUIDANCE
Boulder requires certified-tester portal submission.
Boulder’s official program explains which customer types are tracked, requires certified testers, and sends annual reports through the City’s backflow portal. We match the current account and every listed assembly before filing so a partial submission does not leave the property unresolved.
