Should architectural drawings be kept by industry committee or property management?

It is best to keep it by the property management Committee. These are the most important materials in architecture. If the property management is not good, you can ask to change the property management company. In order to reduce trouble and be held hostage by the property management company, you can leave all the important materials to the property management Committee for safekeeping. Property companies only take copies, and property management generally only uses outdoor comprehensive pipe network diagram or sub-project pipe network diagram, and others are of little use to them. If you really need it, borrow it from the industry Committee.
