How to check this licence yourself
Don't take our word for it — Minnesota publishes this for free, and it takes about a minute:
- Search for PermitStack's own public contractor licence lookup — every state runs one.
- Search licence number BC793840, or the business name MD Structures LLC.
- Check the status reads active and the expiry is in the future.
- Ask to see proof of liability insurance too. State licensing does not cover that, and we cannot verify it.
A licence means the state has certified the holder to do this work. It is not a guarantee of workmanship, price or availability — see ourcontractor hiring checklistfor what else to ask.
