A company appears here when its role on a current work permit contains plumbing wording. This uses the recorded role, rather than guessing a company's trade from the overall job description. Names are source identities; similar names may refer to the same business or to different businesses.
This is the retained Chicago feed window, not complete city or company history. Administrative records, unclear work scope, renewals and records absent from the current source are excluded. Each permit counts once; permits are not unique projects. Issue / ready dates do not establish construction starts. Check collection dates and coverage ↗

Does a listed plumbing role verify the company or its availability?
The role records how a name appears on a permit. It does not independently verify legal identity, licensing, insurance, work quality or availability. Company profiles show any available register evidence separately. Whole-job estimates are not plumbing contract values or company revenue.
