How to read this
The Contractors State License Board lists complaints it has sent for legal action, citations it has issued, and warning letters. A complaint or accusation is an allegation, not a finding. A citation is the board's finding that a rule was broken; the contractor can appeal it. Complaints closed in the contractor's favor are never listed. Most contractors have no items.

Permit timeline

What to ask before you hire
About Safe Quake Construction
- The state lists a case on this license. A case is not a finding. Read it on the state's license page and ask the contractor about it.
- Ask who will do the work. Anyone they pay to work on your home must be covered by workers' comp.
- Ask what the warranty covers and for how long, in writing.
Worth asking any ADU builder
- Can you show me proof of liability insurance and your bond?
- Do you handle the plans, engineering and utility hookups, or do I?
- How long from permit to the final inspection on your last three ADUs?
- What is the payment schedule, and what is extra?
