How to check this licence yourself

Don't take our word for it — California publishes this for free, and it takes about a minute:

1. Search for PermitStack's own public contractor licence lookup — every state runs one.
2. Search licence number 1112994, or the business name DTP Builders.
3. Check the status reads active and the expiry is in the future.
4. 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.
