How to read your results
One checked item isn't necessarily disqualifying — ask about it directly and see how the contractor responds. Two or more checked items is a reasonable signal to slow down and get a second opinion, or compare against another contractor before committing. See our guide to comparing contractor bids for how to evaluate multiple proposals side by side once you've ruled out the clear warning signs.
Where to verify a license directly
You can look up any California contractor's license status, classification, and any disciplinary history directly through the Contractors State License Board (cslb.ca.gov) — this takes a few minutes and doesn't rely on taking the contractor's word for it.
How United Build Partners fits into this
Contractors in our network are expected to meet a standard we describe on our Contractor Standards page — an active license, appropriate insurance, relevant ADU experience, and clear estimating practices. That said, this checklist is still worth using on any contractor you're evaluating, including ones we introduce you to — it's your project, and your own diligence matters.
Frequently asked questions
Not necessarily — ask about it directly first. Some issues have a reasonable explanation. It's a pattern of multiple red flags, or an unsatisfying answer to a direct question, that's worth taking more seriously.
Not always, but it's worth understanding why before assuming it's simply better value — see our guide to comparing contractor bids for how to check whether bids are actually pricing the same scope.
No — nothing you check is saved, stored, or sent anywhere. It resets when you leave or refresh the page.
