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.

AB 2221 (2022) expanded rights for home-based food businesses under the Homemade Food Operations Act. Some cities, including Los Angeles, have updated their home occupation rules to allow more types of businesses post-pandemic.

How California Compares to Neighboring States

California is a higher-cost state for starting a Mental Health Practice, with a cost-of-living index of 142.2 (national average is 100). Compared to neighboring Oregon ($56,000 median startup cost), California has higher costs for a Mental Health Practice.

State	Est. Cost	LLC Fee

Oregon	$56,000	$100
Nevada	$51,000	$425
Arizona	$51,500	$50

Common Mistakes to Avoid

1
Starting insurance credentialing without allowing 60-120 days per payer — you cannot bill until credentialing is complete
2
Joining too many insurance panels at discounted rates — insurance rates of $80-$130/session make it hard to sustain a practice vs. private pay at $150-$250/session
3
Not implementing a cancellation policy — a 48-hour notice policy with fees recovers thousands of dollars per year
4
Underestimating the time to build a full caseload — allow 6-12 months to reach 25-30 clients per week
5
Skipping HIPAA compliance infrastructure — $50K+ in fines for HIPAA violations are common
6
Not having a clear specialty — therapists who specialize (trauma, couples, eating disorders) fill caseloads faster and command higher rates

Next Steps to Launch Your Mental Health Practice

1
Obtain your California counseling or psychology license from the California Board of Behavioral Sciences before seeing clients
2
Register your Mental Health Practice as a professional LLC or PLLC with the California Secretary of State ($70 filing fee)
3
Apply for your NPI (National Provider Identifier) number through NPPES for insurance billing
4
Credentialing with Blue Cross, Aetna, Cigna, and your state Medicaid behavioral health network
5
Get professional liability (malpractice) insurance for mental health practitioners ($1,500–$4,000/year)
6
Implement a HIPAA-compliant practice management and telehealth platform (SimplePractice, TherapyNotes, or similar)
7
Establish your sliding-scale fee policy and intake forms — document informed consent for all treatment approaches
8
Set up your telehealth capabilities for California-licensed virtual sessions to expand your client base

Frequently Asked Questions

Starting a solo therapy practice costs $15,000 to $150,000. A solo therapist starting in a therapy suite or shared office can launch for $15,000-$30,000. A group practice with multiple therapists, a dedicated office, and full billing infrastructure typically requires $50,000-$150,000.

No — therapists can start 100% virtually with telehealth platforms like SimplePractice or TherapyNotes that include HIPAA-compliant video. Many states allow telehealth across state lines with appropriate licensure. A virtual-only practice has startup costs as low as $2,000-$5,000.

Insurance panels pay $80-$130 per session (vs. $150-$250 private pay) but provide a steady stream of referrals. Most therapists use a mixed model: a few insurance panels for volume plus private pay clients for higher per-session income. Consider joining 2-3 major panels and keeping 30%-50% of caseload private pay.

A solo therapist with $3,000-$5,000/month in overhead needs 15-25 insurance clients per week at $100/session to break even. With private pay at $150-$200/session, 10-15 clients per week covers basic overhead. A full caseload of 25-30 weekly sessions generates $130,000-$200,000 in annual revenue.

Insurance credentialing for therapists takes 60-120 days per panel. CAQH profile setup is the first step and takes 1-2 weeks. Start credentialing with BCBS, Aetna, United, and Cigna simultaneously to maximize coverage. While credentialing processes, accept private pay clients to generate income.
