California has one of the highest rates of contractor fraud in the country. Unlicensed contractors operating in Riverside, San Bernardino, and surrounding Inland Empire cities are a persistent problem — and homeowners who hire them often end up with unfinished projects, failed inspections, and expensive repairs. This guide tells you exactly how to protect yourself.
Why Licensing Matters More in California
California requires contractors who perform work over $500 (combined labor and materials) to hold a license issued by the Contractors State License Board (CSLB). This isn't bureaucratic red tape — it's a meaningful protection for homeowners.
A licensed contractor must:
- Pass a written exam in their trade specialty
- Have a minimum of 4 years of journey-level experience
- Carry a $25,000 contractor's bond
- Maintain current workers' compensation insurance
- Submit to disciplinary action from the CSLB for misconduct
An unlicensed contractor has none of these requirements. If they disappear with your deposit, damage your property, or get injured on your job site, you have very limited legal recourse — and your homeowner's insurance may not cover the damage.
How to Verify a Contractor's License (Takes 2 Minutes)
The CSLB maintains a public license lookup tool at cslb.ca.gov. Before you agree to anything, verify:
- The license number is active and in good standing
- The license holder's name matches the person or company you're dealing with
- The license classification covers the work you need (B-General Building, C-8 Concrete, C-20 Warm-Air Heating, etc.)
- The bond and workers' compensation are current
- There are no serious disciplinary actions or judgments on record
A legitimate contractor will give you their CSLB license number without hesitation. If they seem reluctant, change the subject, or give you a number that doesn't match on the CSLB site — walk away. This is the most common first step in contractor fraud.
Insurance: What to Require
Licensing is necessary but not sufficient. You also need to verify insurance independently. Ask for:
- General Liability Insurance (minimum $1,000,000 per occurrence) — Covers property damage and third-party bodily injury that occurs during the project.
- Workers' Compensation Insurance — Protects you from liability if a worker is injured on your property. If an uninsured worker falls and gets hurt at your home, you could be held personally liable.
Ask the contractor to provide a Certificate of Insurance with your name listed as an additional insured. Any reputable contractor will do this without complaint — it's standard business practice.
Questions to Ask Before Hiring
Once you've verified license and insurance, a good contractor interview covers:
- "Have you done similar projects in Riverside County recently?" Local experience matters for permit familiarity and supplier relationships.
- "Who will be doing the actual work — your crew or subcontractors?" Some contractors are essentially brokers. Know who is on your jobsite.
- "Can you provide 3 references from projects in the last 12 months?" Recent references from similar jobs are far more valuable than old ones.
- "What permits will you pull for this work?" Any contractor who suggests you don't need permits for electrical, plumbing, or structural work in Riverside County is either wrong or cutting corners.
- "What is your payment schedule?" A large upfront deposit is a red flag (see below).
Red Flags That Should Stop You Cold
- Demands a large cash deposit (over 10% or $1,000, whichever is less) — California law limits upfront deposits for most home improvement contracts. A contractor demanding 30–50% upfront is violating the law and/or setting up to disappear.
- No written contract or a very vague one — Every legitimate project should have a written contract specifying scope of work, materials, timeline, and payment schedule.
- Quote dramatically lower than everyone else — If three contractors quote $25,000 and one quotes $10,000, something is wrong. They're either planning to cut corners on materials, planning change-order fraud, or aren't licensed.
- High-pressure tactics ("This price is only good today") — A professional contractor is not running a timeshare sales operation. Any legitimate quote should be good for at least 30 days.
- No physical address — Be wary of contractors with only a cell number and a P.O. box. A legitimate business has a verifiable address.
- Wants to pull permits in your name ("owner-builder") — This transfers legal liability for the work to you. Never agree to this unless you understand exactly what it means.
Understanding Your Contract
California law requires home improvement contracts over $500 to be written and signed. Your contract should include:
- Contractor's name, address, phone, and license number
- A detailed description of the work to be performed (scope)
- Materials to be used (brand, model, color where applicable)
- Start date and estimated completion date
- Payment schedule tied to project milestones (not calendar dates)
- A change order process (written authorization required for any work beyond scope)
- A three-day right to cancel (required by CA law)
Document everything — take photos at each stage, save all text and email communications, and keep copies of all invoices and receipts. This protects you if a dispute arises and provides a record if you ever sell the home.
Why Local Reputation Matters
For contractors in a local market like Riverside County, online reputation is everything. A contractor with 50+ Google reviews and a consistent 5-star rating has something to protect — they won't risk their reputation by cutting corners on your project. Check Google, Yelp, and the CSLB disciplinary history. Also ask neighbors and friends for referrals — word-of-mouth in local communities is still the most reliable signal.
