Choosing the wrong contractor is the most expensive mistake an East Bay homeowner can make. A bad hire doesn't just cost money — it can mean months of delays, code violations that come back at resale, or work that needs to be torn out and redone. The good news is that most of the risk can be eliminated before you sign anything.
Here's exactly what to verify, what to ask, and what to walk away from.
Step 1: Verify the CSLB License
In California, any contractor doing work valued over $500 must be licensed by the Contractors State License Board (CSLB). This is not optional — it's the law. And verifying a license takes about 60 seconds.
Go to cslb.ca.gov and search by the contractor's name or license number. You'll see whether the license is active, what classifications it covers (B = General Building, C-8 = Concrete, etc.), whether there are any disciplinary actions on record, and whether the bond and workers' comp are current.
Important: A CSLB license is separate from a business license. Many unlicensed contractors have a city business license and present it as proof of legitimacy. Always verify directly at cslb.ca.gov.
Step 2: Confirm Insurance
A licensed contractor should carry two types of insurance:
- General liability insurance — covers damage to your property during the project. Ask for a certificate of insurance and verify the coverage amount (minimum $1M per occurrence for most home projects).
- Workers' compensation insurance — covers injuries to workers on your property. If a worker is injured on your job and the contractor has no workers' comp, you can be held liable.
Ask the contractor to have their insurer send you a certificate of insurance directly — not just a copy the contractor provides — so you know it's current.
Step 3: Check References — the Right Way
Every contractor will give you a reference list of happy customers. What matters is how you use it. When you call references, ask specific questions:
- Did the project finish on or near the original timeline?
- Were there cost overruns? If so, why, and were you notified before they happened?
- How was communication during the project — did you always know what was happening?
- Were there any issues after completion, and how were they handled?
- Would you hire them again without hesitation?
Also look for reviews on Google, Yelp, and Houzz — not just the star rating but the pattern of responses to negative reviews. A contractor who handles criticism professionally is usually one who handles project problems the same way.
Step 4: Understand the Bid
Get at least three bids for any project over $10,000. When comparing them, focus less on the total number and more on what each bid actually includes. A bid that's $8,000 lower might be excluding permits, or using lower-grade materials, or leaving out work that will need to be done eventually.
A complete bid should specify:
- Scope of work in detail (not just "kitchen remodel" but every element)
- Materials with brand and grade specified
- Whether permits are included
- Payment schedule tied to project milestones
- Timeline with start date and estimated completion
- What's explicitly excluded
On payment schedules: California law limits a contractor's initial deposit to 10% of the project cost or $1,000, whichever is less. A contractor asking for 30–50% upfront is a warning sign — and potentially illegal.
Red Flags to Walk Away From
🚩 Large cash-only upfront payment. Legitimate contractors use written contracts and accept checks or transfers. Cash-only deals offer you no protection and no paper trail.
🚩 No permit pulled. If a contractor offers to "save you money" by skipping permits, they're exposing you to serious risk — unpermitted work can be a dealbreaker at resale and can make you liable for bringing it up to code at your own expense later.
🚩 Pressure to decide immediately. Good contractors are busy but not so busy that they can't give you 48–72 hours to review a bid. High-pressure sales tactics are a sign of someone who doesn't want you to compare or think carefully.
🚩 No written contract. Every project should have a written contract. California law requires it for jobs over $500. A contractor who resists putting things in writing has something to hide.
