Congratulations — you passed your CSLB exams and your contractor license is active. Now what? The first 90 days after getting licensed are critical. The decisions you make and the systems you set up in this window will determine whether your business gets off to a strong start or stumbles out of the gate.
This guide gives you a practical, day-by-day roadmap for launching your California contracting business the right way — from bonds and insurance to landing your first clients.
Week 1: Handle the Legal and Financial Essentials
Day 1-2: Secure Your Contractor Bond and Insurance
If you have not already filed your $25,000 contractor bond as part of the licensing process, do this immediately. Your license is not fully active without it.
Beyond the required bond, you need insurance. While the CSLB does not require general liability insurance, operating without it is a recipe for financial disaster. Get these in place on day one:
- General liability insurance: $1 million to $2 million in coverage is standard. Expect to pay $500-$2,000+/year depending on your trade and revenue. Most clients and general contractors will require this before hiring you.
- Workers’ compensation insurance: Required if you have any employees. If you are a sole owner with no employees, you can file an exemption with the CSLB — but understand that this means you have no coverage if you are injured on the job.
- Commercial auto insurance: If you use a vehicle for business, your personal auto policy likely does not cover commercial use.
- Tools and equipment coverage: Protects your investment in tools, which can easily total $10,000-$50,000+.
Day 3-4: Set Up Your Business Entity
If you have not already established a formal business entity, now is the time. Your main options:
- Sole proprietorship: Simplest structure, no formation required, but no liability protection
- Corporation (S-Corp): Better tax treatment above $50-60K profit, no extra CSLB bond
- LLC: Liability protection, but requires an additional $100,000 CSLB bond in California
Whichever you choose, you will need:
- EIN (Employer Identification Number): Free from the IRS, takes 5 minutes online at irs.gov
- Business bank account: Never mix personal and business finances. Open a dedicated checking account using your EIN.
- Accounting system: Set up QuickBooks, FreshBooks, or even a simple spreadsheet to track income and expenses from day one. This will save you enormous headaches at tax time.

Day 5: City and County Business Registration
Most California cities and counties require a business license or business tax certificate to operate within their jurisdiction. Requirements and fees vary widely:
- Check with your city’s business license department (most have online applications)
- If you work in multiple cities, you may need licenses in each one — though some cities have reciprocal agreements
- Some cities require a home occupation permit if you run your business from home
- Fees typically range from $50-$500 per year depending on the city
Do not skip this step. Operating without a local business license can result in fines and creates a compliance issue if a client or competitor reports you.
Weeks 2-3: Build Your Business Foundation
Create Your Contract Template
California law has specific requirements for home improvement contracts. Every contract over $500 must include:
- Your contractor license number
- A detailed description of the work to be performed
- The total contract price and payment schedule
- Approximate start and completion dates
- A notice of the homeowner’s right to cancel within 3 business days (for contracts signed at the homeowner’s residence)
- Required CSLB disclosure statements
Have a lawyer review your contract template. A poorly written contract is worse than no contract — it gives you a false sense of security while leaving you legally exposed.
Set Up Your Estimating Process
Professional estimates win jobs. Create a standardized estimating process that covers:
- Site visit checklist: What to look for and measure at every job site
- Material pricing: Build relationships with suppliers and get contractor pricing accounts
- Labor costing: Know your hourly rate and how long tasks take — track this from your very first job
- Markup and margin: Most contractors use a 1.5x to 2x markup on costs. Understand the difference between markup and margin.
- Written estimate template: Professional-looking estimates with your company name, license number, and itemized pricing
Understand CSLB Advertising Rules
The CSLB has strict rules about how contractors advertise. Violations can result in fines and disciplinary action. Key rules include:
- License number required: Your CSLB license number must appear on all advertising — business cards, website, truck lettering, flyers, social media, online ads, everything
- Correct license classification: You can only advertise services within your license classification. A C-10 (Electrical) contractor cannot advertise plumbing services.
- Business name must match: The business name in your advertising must match the name on your CSLB license record
- “Licensed contractor” claims: If you use the term “licensed,” your license number must be displayed
- No misleading claims: You cannot imply qualifications or certifications you do not hold
Check the CSLB website for the full advertising guidelines. These rules apply to every platform — including Yelp, Google Business, Nextdoor, and social media.
Weeks 4-6: Start Getting Clients
Set Up Your Online Presence
For most contractors, your first clients come from a combination of referrals and online visibility. At minimum, set up:
- Google Business Profile: This is the single most important online listing for local contractors. It is free and shows up in Google Maps and local search results. Complete every field, add photos of your work, and ask satisfied customers to leave reviews.
- Simple website: Even a one-page website with your services, license number, contact information, and a few project photos establishes credibility. You can build one for under $200/year.
- Yelp Business listing: Many homeowners use Yelp to find contractors. Claim your free listing and fill it out completely.
Build Your Referral Network
The most profitable contracting businesses run on referrals. Start building your network from day one:
- Real estate agents: They constantly need reliable contractors for pre-sale repairs and buyer requests
- Property managers: Ongoing maintenance contracts provide steady income
- Other contractors: Specialty contractors refer work outside their classification. A plumber who does not do electrical work will refer a C-10 contractor they trust.
- Previous employers and coworkers: Let everyone in your professional network know you are licensed and taking work
Price Your First Jobs Carefully
New contractors commonly make one of two pricing mistakes:
- Pricing too low: Winning jobs by undercutting the market sounds smart, but you end up working harder for less money and attracting price-sensitive clients who are difficult to work with
- Pricing too high: Without a portfolio or reviews, premium pricing is hard to justify
For your first 5-10 jobs, price competitively (not cheaply) and focus on doing excellent work that generates reviews and referrals. These early jobs are an investment in your reputation.
Weeks 7-12: Systematize and Grow
Track Everything
From the beginning, track these numbers:
- Job costs vs. estimates: How accurate are your estimates? Adjust your estimating formulas based on real data.
- Time per job type: Build a database of how long different tasks take so your future estimates are based on facts, not guesses.
- Lead sources: Where are your clients finding you? Double down on what works.
- Cash flow: Know your income and expenses weekly. Cash flow problems kill more contracting businesses than bad workmanship.
Stay Compliant
Keep your license in good standing by staying on top of:
- Bond renewal: Your surety bond must remain active continuously
- Workers’ comp: If you hire any employees — even part-time — get workers’ comp coverage immediately
- License renewal: CSLB licenses renew every 2 years. Do not let yours lapse.
- Continuing education: While not currently required for license renewal, staying current on codes and best practices makes you more competitive
Plan for Taxes
As a self-employed contractor, taxes will not be withheld from your income. You are responsible for:
- Quarterly estimated tax payments: Due April 15, June 15, September 15, and January 15
- Self-employment tax: 15.3% on net earnings (in addition to income tax)
- California state income tax: Varies based on income
- Franchise tax: $800/year minimum for LLCs and corporations
Set aside 25-30% of every payment you receive for taxes. Better yet, open a separate savings account just for tax payments. Many new contractors get hit with a large, unexpected tax bill in April because they did not plan for quarterly payments.
Common First-Year Mistakes to Avoid
- No written contracts: Always use a written contract, even for small jobs. Verbal agreements lead to disputes.
- Mixing personal and business money: Use a separate business bank account from day one.
- Taking on too much: Overcommitting and missing deadlines damages your reputation faster than anything else.
- Skipping insurance: One accident or lawsuit without insurance can end your business before it starts.
- Ignoring the books: Track income and expenses from your first dollar. Catching up later is painful and expensive.
- Not marketing consistently: Even when you are busy, keep building your online presence and referral network. Feast-or-famine cycles are the result of marketing only when work is slow.
