Licenses & Permits in California

General Business License

California does not have a statewide general business license, but most cities and counties require a local business license or business tax certificate. Businesses must register with the California Secretary of State for entity formation, obtain a seller's permit from the California Department of Tax and Fee Administration if selling taxable goods, and register with the EDD for payroll taxes if employing workers. San Francisco, Los Angeles, and other major cities have their own business registration and tax requirements.

Common Mistakes to Avoid

1
Underestimating material costs and change order frequency
2
No lien waiver process protecting cash flow
3
Subcontractors without proof of insurance
4
Poor project scheduling causing costly delays
5
No written contracts with payment schedules

Next Steps to Launch Your General Contracting Business

1
Form your LLC or corporation in California — general contractors carry significant liability for subcontractor work and project defects (filing fee: $70)
2
Obtain your California general contractor license — requires experience documentation, exam, and financial statements in most states
3
Obtain a contractor surety bond and general liability insurance — bond requirements vary by state and the GL premium is typically a meaningful four-figure annual cost; both are required for most permits and contracts
4
Complete OSHA 30-Hour Construction Safety training — required by most commercial project owners and insurance carriers
5
Register with California Contractor State License Board or equivalent regulatory agency and maintain license with required continuing education
6
Build a subcontractor network: licensed plumbers, electricians, HVAC techs, and framers — GCs depend on reliable subs for project quality
7
Create a construction contract template using AIA or AGC contract forms covering scope, payment schedule, change orders, and warranty
8
Get workers' compensation insurance before hiring any employees or subcontractors — California requires WC for all construction workers

Frequently Asked Questions

Starting a general contracting business typically requires a low-to-mid five-figure investment, covering contractor licensing, surety bond, liability insurance, workers comp, a reliable work vehicle, tools, and working capital. Materials for active projects can require significant additional capital.

Most states require general contractors to be licensed. Requirements vary — some require passing a trade exam, others require proof of experience and financial responsibility. California, Florida, and Texas have strict requirements. Check your state contractor licensing board for specific requirements.

GCs earn a meaningful markup on subcontractor labor and materials — typically a low-to-mid double-digit percentage. On a substantial six-figure remodel, that markup translates into a healthy five-figure gross. After overhead, net margins are modest. Larger commercial projects have lower margins but higher volume; custom residential work commands meaningfully higher margins.

If subcontractors are true independent contractors with their own workers comp, the GC may be exempt. But if a subcontractor lacks coverage, the GC's policy may pay their claims. Always verify subcontractor insurance certificates — liability flows to the GC in most states.
