The report wouldn’t have existed unless the client contacted the inspector and contracted for inspection.
The client paid for the inspection.
Some inspectors claim that their reports are copyrighted. I know that I have verbiage baked in to my report stating that Good Home Inspection reserves the right use the report and images or videos associated with the report in part or whole for training purposes and/or advertising after any and all personal information and other property identifiers such as metadata or digital location markers have been removed.
The inspection report is the client’s intellectual property. The home inspector and/or inspection company is merely the Custodian of Record. The report is for the client to keep or share whichever way best suits their interest.
The inspector is not required to store reports, although most inspectors hang on to them for a couple of years. So if your report is important to you, then you had better keep your report on a couple of drives (in case one fails). I’m not a real estate agent or an attorney.
