Thank you and if the owner has signed nothing? What is the consequence?
You can check the licening on the cslb website license search page. The City should have required something in writing from the owner before issuing a permit on the request of a contractor or subcontractor. The general may have authorized the sub to pull the permit, but there must have been something in writing first from the owner authorizing the contractor or sub to do so. You should check with the building department to determine what happend, and have the owner's name put on the permit.
