Ultimate Checklist for Starting a Contractor Business: 10 Steps to Success
Starting a contractor business in California is one of the most rewarding paths for skilled tradespeople—but it’s also one of the most regulated. With over 240,000 licensed contractors overseen by the CSLB, competition is fierce and compliance is non-negotiable. To succeed, you need more than tools and experience—you need the right licenses, bonds, insurance, and strategy to grow your business and protect your clients.
This guide gives you the ultimate 10-step checklist for starting your contractor business in 2025, plus tailored tips for plumbers, roofers, electricians, landscapers, carpenters, HVAC contractors, and handymen.
1. Choose Your Business Structure
Your legal structure determines your liability protection and taxes:
Sole Proprietorship: Easy setup but no personal liability protection.
LLC: The most common choice for contractors—protects personal assets while remaining flexible.
Corporation: Best for large operations with multiple partners.
💡 Tip: Most new contractors prefer forming an LLC to protect personal assets in case of lawsuits or unpaid claims.
2. Register Your Business Name
Pick a professional name that clients will trust. If it differs from your legal name, file a Fictitious Business Name (FBN) in your county.
Make sure your business name matches CSLB records exactly to avoid licensing delays.
3. Apply for a Contractor’s License
In California, any project worth more than $500 requires a contractor’s license from the CSLB.
Steps include:
Submitting proof of 4 years’ journey-level experience.
Passing the Law & Trade exam.
Filing a $25,000 contractor license bond.
Paying state licensing fees.

4. Secure Your Contractor License Bond
A $25,000 California contractor bond is mandatory for all contractors. This protects consumers, employees, and suppliers if you fail to meet state regulations or pay wages.
Other bonds may include:
Bond of Qualifying Individual (BQI) – $25,000 if your license is qualified by an RME/RMO.
$100,000 LLC Employee/Worker Bond – for LLC contractors.

5. Obtain Contractor Insurance
Insurance isn’t just a safety net—it’s often a contract requirement.
Core coverages include:
General Liability Insurance – protects against property damage & injuries.
Workers’ Compensation – required if you hire employees.
Tools & Equipment Insurance – covers theft or damage to your gear.
Commercial Liability – crucial for small construction businesses.

6. Build a Financial System
Open a business bank account.
Set up accounting software to track expenses and payroll.
Budget for insurance premiums, bonds, and renewals.
7. Stay Compliant With Renewals
Your license, bond, and insurance must stay active.
CSLB licenses expire every 2 years.
Bonds must be renewed before expiration.
Insurance should always remain in force.
