The written estimate: moving rules Oregon makes different

Oregon regulates in-state household goods moves harder than most states, and the written estimate is where that shows up first. Knowing the rules turns the estimate conversation from a sales pitch into a document you can hold the company to.
What the state requires
Any company carrying household goods between two points in Oregon must hold an ODOT certificate of authority, and certified movers must give you a written, signed estimate. The estimate can only be made after a visual inspection of the goods, in person or by a real-time video walkthrough. An oral quote or a firm price offered over the phone without anyone seeing your load is not a legal estimate here, it is a company cutting a corner that exists to protect you.
What it doesn't do
The Oregon estimate is not binding. The final bill follows the actual work performed: worker-hours on an hourly move, or weight and distance on a rated one. What the estimate gives you is the itemized picture of what the job was expected to take, which is what makes a padded bill arguable later. If the mover can't tell you what would change the number, ask before signing.
The paper you should also get
Certified movers must hand every customer the state's General Information Bulletin for moving household goods before the job. It lays out your rights, the estimate rules, and where complaints go. If the mover doesn't produce it, that is worth a question.
Your part of the inspection
The estimate is only as good as what the inspector sees. Show the attic, the garage, the storage unit, the piano in the back room. Underestimating the load is how honest estimates turn into surprising bills, and the fix is visibility, not optimism.
