How to Vet a Ventura County Contractor

The Contractors State License Board issues about 3,400 new C or B licenses in Ventura County each year. Most are good people. Some are not. This guide walks through what to verify, what to demand in writing, and the 8 questions that expose whether someone is actually going to build your project.

Do these 5 things before you sign anything

CSLB license lookup at cslb.ca.gov — active, correct classification, no disciplinary actions.
Request a current Certificate of Insurance, listing you as additional insured.
Verify bond is posted and current.
Walk a live jobsite they're currently running.
Get 3 references from projects completed 12–24 months ago (not last week).

Step 1: License lookup (do this first, always)

Every California contractor must be licensed by the Contractors State License Board for projects over $500. Look them up at cslb.ca.gov by the license number on their business card, contract, or vehicle.

Verify:

Status: Active. "Inactive," "Expired," or "Revoked" means walk away immediately.
Classification matches the scope. For a full remodel, you want a B (general building) license. Kitchen or bath only with no structural work can sometimes be done under a C specialty — but a B gives the most coverage.
Bond posted. $25K minimum for all licensees. Many reputable firms post larger bonds ($100K+). Low bond isn't disqualifying, but paired with other red flags it's a signal.
Workers' comp active. If they have employees, this must be current. If they claim to have no employees, verify on site — if 8 guys show up, somebody's wrong.
No disciplinary actions. A single old complaint with a small civil penalty isn't disqualifying. Multiple actions, citations, or license suspensions in the last 5 years are disqualifying.

Step 2: Insurance proof (before you sign)

Ask for a Certificate of Insurance (COI) issued directly from their carrier or broker, dated within the last 30 days. Do not accept a screenshot or photocopy. Good COIs show:

General liability at least $1M per occurrence / $2M aggregate.
Workers' comp (required by CA for all W-2 employees).
You listed as "additional insured" for the project address.
Umbrella policy if project is over $100K.

Step 3: The 8 questions that expose a hat contractor

"Hat contractor" is the industry term for a salesperson who holds the license but subcontracts 100% of the work to whoever's cheap this week. They deliver inconsistent quality because there's no continuity of crew. These 8 questions tend to expose them:

1. Who will be my day-to-day foreman, and is he on your payroll?

Why it matters: Real generals have a foreman on W-2. A hat contractor will dodge or say "we'll assign one."

2. Can I walk a jobsite you're running right now?

Why it matters: Real generals say yes and name two or three addresses.

3. What percent of the work do you subcontract vs. self-perform?

Why it matters: 100% subcontracted = hat contractor. 60–85% self-performed + known trade subs is normal.

4. What's your typical crew size on a kitchen remodel?

Why it matters: Real answer: "3–5 on build days, plus subs for tile and counters." Vague = problem.

5. When's your soonest permit pull date if we signed today?

Why it matters: If they say "next week" with no discussion of plan review, they're not actually permitting.

6. What's your last change-order ratio on comparable projects?

Why it matters: Under 5% = well-estimated. Over 15% = they underbid intentionally, then eat you on changes.

7. Can I see 3 references from projects completed 12–24 months ago?

Why it matters: Projects from last month haven't had time to develop warranty issues. Older references are more honest.

8. Who pulls the permit — you or me?

Why it matters: A contractor who wants YOU to pull the permit is trying to shift liability for code violations to you. Walk.

Step 4: Protect yourself on payment

California limits the down payment to 10% of the contract price or $1,000, whichever is less. That's a hard statutory cap (BPC §7159.5) — not negotiable. Any contractor who pushes for 20%+ up front is either ignorant of the law or running your money as operating capital.

Pay progress payments tied to milestones:

10% at contract signing
15–20% when permit is pulled and materials ordered
20% at rough-in inspection pass
20% at drywall complete
20% at substantial completion (last day of regular work)
5–10% retention, released after final inspection + all punch-list items fixed

Require conditional lien releases with each progress payment (from the general and every sub and supplier whose work is covered by that payment). Unconditional releases at final payment. This is standard under California Civil Code §8132-8138. If a contractor doesn't know what lien releases are, that alone tells you something.

Step 5: Read the contract before you sign

Your contract should specify:

Exact scope of work (cabinet model numbers, specific materials, spec sheets attached)
Fixed price (not time & materials, unless you know what you're signing up for)
Start date and substantial completion date
Payment schedule tied to milestones, not dates
Change order process in writing with mark-up cap
Who pulls permits (should be the general)
Warranty period (1 year minimum; quality firms offer 5–10 years on workmanship)
Clean-up and final-walkthrough clause
Signed contract + CSLB-required "Notice to Owner" language

Frequently asked questions

How do I check if a California contractor is really licensed?▾

Go to cslb.ca.gov and search the license number they put on their business card or ad. Verify: current status is "Active," classification matches the work (B for general building), bond is posted ($25K minimum, many reputable firms post $100K+), workers' comp is active if they have employees, and there are no recent disciplinary actions. Do not take a contractor's word — always check the database yourself.

What's a "hat contractor" and how do I spot one?▾

A "hat contractor" is someone who subcontracts 100% of the work but marks themselves as the licensee. Signs: no jobsite foreman from their own company, every worker is from a different subcontractor LLC, the sales rep never visits the site after signing, quotes are aggressive but scope is vague. Real general contractors have a crew they employ or long-term sub relationships — and will answer this question directly.

Should I ask to see proof of insurance?▾

Always, and before you sign. Ask for a current Certificate of Insurance (COI) listing you as additional insured. Verify: general liability ($1M+ per occurrence), workers' comp (required by CA law if they have any employees), and auto if they use trucks on the job. If a contractor balks at this, walk.

What are mechanic's liens and how do I protect myself?▾

A subcontractor or supplier who isn't paid by your general contractor can file a mechanic's lien against your property — even if you paid the general in full. Protection: require conditional lien releases (from each sub and supplier) when you pay each progress payment, and unconditional releases when final payment clears. This is California Civil Code §8132-8138 — standard forms your contractor must provide.

What payment schedule should I expect?▾

California law limits the down payment to 10% of the contract price or $1,000, whichever is less (BPC §7159.5). Anything more is illegal. Progress payments tied to verifiable milestones (permit pulled, rough-in inspected, drywall complete) are standard. Never pay for material before it's on site. Hold 5–10% retention until all punch-list items and inspections are complete.
