How to Start a Fitness Studio or Gym Business in California

How to Start a Gym in California: Costs, Licenses, and the Rules Nobody Warns You About

California has a specific law governing fitness businesses that sell memberships. Most states don’t. The California Health Studio Services Contract Law, enforced by the Department of Consumer Affairs (DCA), means your gym isn’t just a retail business — it’s a regulated service provider with mandatory contract terms, cancellation rights, and financial security requirements built into state law.

That’s before you hit the $800 annual franchise tax, mandatory workers’ comp for your first hire, AB5 trainer classification rules, and commercial lease rates that run 2-3x the national average.

This guide covers everything you need to open legally — and what the actual numbers look like.

Health Studio Registration

If your gym sells memberships, you’re subject to the California Health Studio Services Contract Law. That’s most gyms. If you’re taking money upfront for future services — monthly memberships, annual passes, class packages — this law applies to you.

Register with the DCA

Health studio registration costs approximately $100 per year and runs through the DCA. This isn’t optional. Operating without registration while selling membership contracts exposes you to enforcement action and, more practically, makes your membership agreements legally unenforceable.

Membership Contract Requirements

This is where the law gets detailed. Your membership agreements must include specific disclosures about:

  • Cancellation rights. Members have the right to cancel within five business days of signing for a full refund. This is a hard statutory right — you can’t contract around it.
  • Refund policies. If the facility closes or moves more than five miles and a member doesn’t want to follow, they’re entitled to a prorated refund.
  • Contract term limits. Month-to-month is safest. Contracts longer than one year face additional scrutiny and restrictions.
  • Fee transparency. All fees must be disclosed clearly in the contract — no burying initiation fees in fine print.

Financial Security Requirements

If you collect prepaid fees totaling more than a certain threshold, California may require you to post a bond or maintain a trust account to protect member funds. The purpose is simple: if your gym closes, members get their prepaid money back. The exact threshold and bond amount depend on your volume of prepaid contracts. Your attorney or the DCA can give you the current specifics for your situation.

City Business License

Separate from state registration, every California city requires a local business license. Cost varies wildly — Los Angeles charges based on gross receipts, San Francisco has its own fee schedule, and smaller cities often charge a flat $50-$200. Check with your city’s business licensing office before you open. Some cities also have zoning requirements that specifically affect fitness uses — especially if you’re planning on early morning or late-night hours.

California’s Cost Structure for Gym Owners

Here’s the honest version: California costs more. Not marginally. Structurally.

LLC Formation and the $800 Franchise Tax

Filing an LLC costs $70 (Form LLC-1) through the California Secretary of State. You also need to file a Statement of Information within 90 days for $20. Neither of those is the problem.

The problem is the $800 annual franchise tax due to the California Franchise Tax Board. Every LLC in California owes this — regardless of whether you made money, regardless of whether you opened your doors yet. It’s due in the first year and every year after. Budget it as a fixed cost.

Workers’ Comp: Mandatory for Every Employee

California has no minimum employee count before workers’ comp becomes mandatory. Hire one front desk person, you need workers’ comp. Hire one part-time cleaning staff, you need workers’ comp. This is not like some states where the requirement kicks in at five or ten employees.

For a gym, this matters because you’re adding workers’ comp costs at the same time you’re paying for equipment and build-out. Workers’ comp premiums for fitness industry employees typically run 2-4% of payroll, though your exact rate depends on classification codes and your claims history.

Minimum Wage: $16.90/Hour in 2026

California’s minimum wage is $16.90 per hour as of 2026. For a gym running on front desk staff, attendants, and part-time instructors, your labor costs per hour are significantly higher than most other states. A front desk employee working 30 hours a week costs you at minimum $507 in gross wages before payroll taxes, benefits, or workers’ comp.

If you’re planning to keep labor costs lean with independent contractors — specifically personal trainers — read the next section carefully.

AB5 and the Trainer Classification Problem

California’s AB5 law significantly restricts who qualifies as an independent contractor. The default assumption is employment. To treat someone as a contractor, you must pass the ABC test:

  • The worker is free from your control in how they perform the work
  • The work is outside your usual course of business
  • The worker is independently established in that trade

Personal training is almost always the “usual course of business” for a gym. That means point B fails automatically. Most gyms cannot legally classify their in-house trainers as independent contractors under AB5. They’re employees — which means payroll taxes, workers’ comp, and minimum wage guarantees apply.

Some gym owners get around this by renting space to trainers who operate their own independent businesses and bring their own clients. That model can work under AB5, but it needs to be structured carefully. The trainer can’t be your de facto employee with a 1099 stapled on top.

This is worth getting right. AB5 enforcement and wage claims are expensive.

Commercial Lease Rates

Expect $2-$5 per square foot per month in California metro areas — and that’s not the high end. In Los Angeles, San Francisco, San Jose, or San Diego, you can easily hit $5-$8/sq ft for desirable retail or mixed-use space with adequate parking and ceiling height for fitness use.

A 3,000 sq ft boutique studio at $3.50/sq ft costs $10,500/month in rent. A 10,000 sq ft full gym at $4/sq ft is $40,000/month. Those numbers shock people who’ve looked at gym costs in Texas or the Midwest.

You also need to factor triple net (NNN) leases, which pass property taxes, insurance, and maintenance back to the tenant. Budget another $0.50-$1.50/sq ft on top of base rent.

Build-out costs run 30-50% higher in California than the national average due to prevailing wage rules, construction material costs, and permit fees. A gym fit-out that costs $80,000 in another state might run $110,000-$120,000 here.

Startup Costs: What You’re Actually Looking At

There’s no single number for what a gym costs to open. But here’s a realistic breakdown based on California-specific pricing.

Formation and Registration

  • LLC filing: $70
  • Statement of Information: $20
  • Annual franchise tax: $800
  • Health Studio registration: ~$100

Total: roughly $1,000 in year one, not counting attorney fees if you use one.

Equipment

Equipment is your biggest variable. A boutique yoga or Pilates studio can open with $25,000-$40,000 in equipment. A functional fitness gym or CrossFit-style space might run $40,000-$80,000. A full commercial gym with cardio equipment, free weights, machines, and locker rooms can easily hit $100,000-$150,000+. Used equipment can cut costs significantly, but budget for maintenance and replacement.

Build-Out

This is where California gets expensive fast. Permitting alone takes longer and costs more here than most states. Budget:

  • Boutique studio (light build-out, 1,500-2,500 sq ft): $30,000-$75,000
  • Mid-size gym (2,500-6,000 sq ft): $75,000-$150,000
  • Full commercial gym (6,000+ sq ft): $150,000-$300,000+

Higher-end finishes, HVAC upgrades for ventilation, showers, and locker rooms add significant cost. And California’s seismic and ADA requirements add complexity to any renovation.

Insurance

General liability insurance for a gym runs $1,500-$3,000/year for a small studio. Add professional liability (especially if you’re offering personal training), commercial property coverage, and general business coverage, and total insurance costs typically land at $2,000-$5,000/year. Workers’ comp is separate.

Total Estimates

Putting it together:

  • Boutique fitness studio (yoga, Pilates, cycling, barre — 1,500-3,000 sq ft): $60,000-$120,000 in startup costs. Achievable with used equipment, a favorable lease, and minimal build-out.
  • Full gym or functional fitness facility (3,000-10,000+ sq ft): $150,000-$700,000+. The wide range reflects equipment choices, lease terms, build-out scope, and whether you’re taking over a space that’s already gym-ready.

These numbers assume you’re leasing, not buying real estate. They don’t include operating capital — you’ll want 3-6 months of fixed costs (rent, payroll, insurance, utilities) in reserve before you open.

Practical Steps to Open

You’ve seen the costs. Here’s the sequence.

1. Form your LLC

File Form LLC-1 at bizfileOnline.sos.ca.gov. $70. Then file your Statement of Information within 90 days for $20. Get your EIN from irs.gov/ein — it’s free and takes about five minutes online.

2. Register with the DCA

File your health studio registration with the Department of Consumer Affairs. Do this before you start selling memberships. ~$100/year.

3. Draft compliant membership agreements

Your membership contracts need to comply with the Health Studio Services Contract Law. This is worth paying an attorney for — one properly drafted template protects you for years. Get the cancellation rights language right. Get the refund policy right. Make the fees transparent.

4. Get your city business license

Check your city’s requirements. Some cities also require a Certificate of Occupancy before you can open a fitness facility, especially if you’re doing construction.

5. Set up payroll and workers’ comp

Before you hire anyone, you need workers’ comp coverage in place. California’s State Compensation Insurance Fund (SCIF) covers employers who can’t find private coverage, but shop private carriers first. Set up payroll through a service that handles California withholding — California payroll rules are genuinely complex.

6. Review your trainer classification

Before you open, decide how you’re structuring trainer relationships. If they’re employees, set up the payroll. If you’re running a space-rental model, document it properly. Don’t assume a 1099 is fine because it’s easier.

The Real Question

California gyms can be very profitable. The state has high incomes, strong fitness culture, and dense metro populations. You’re not going to run out of potential members in Los Angeles or the Bay Area.

But the cost structure is real. The $800 franchise tax hits before you make your first dollar. Workers’ comp kicks in at your first employee. AB5 means your trainers are likely employees. And your rent is probably your biggest monthly expense by a wide margin.

The gym owners who succeed here usually do one of two things: run a premium boutique model with high per-member revenue, or build toward multi-location scale where fixed overhead gets distributed. The middle ground — a mid-size gym competing on price with thin margins — is the hardest place to be in California.

Go in with accurate numbers. The DCA registration and contract compliance are manageable. The financial model is where you need to do the work.
