Guide 5 of 13 to opening a gym · Decide
Legal checklist before you open a gym
Before a gym or studio opens, the legal work falls into eight areas. The premises and their permitted use, business registration, staff qualifications and insurance come first. Then member contracts and waivers, data protection, music licensing, and the notices and records you must keep. The details change from country to country, and often from city to city. This checklist gives you the questions to ask in each area, so a local lawyer, accountant and insurer can answer them quickly. It is not legal advice. Confirm every point with someone who knows the rules where you are.

Who to talk to
| Person | What they answer |
|---|---|
| Local planning or licensing authority | Whether the building can be a gym, and what permits you need |
| Accountant | Business structure, registration, sales tax, payroll |
| Lawyer | Lease, membership terms, waivers, consumer and privacy rules |
| Insurance broker | Liability, property, member accident and employer cover |
| Fitness or sports body | Whether coaches or technical leads need a licence |
1. The premises
- Is gym or sports use permitted in this building? If not, how long does a change of use take?
- Is there a separate permit to open a sports facility to the public?
- Which fire safety, occupancy and accessibility rules apply?
- Do signs on the building need their own permit?
- Are there noise limits or opening-hour limits for this area?
What to measure and ask about a space before signing has its own guide. Choosing a space for your gym or studio
2. The business
- Which legal structure fits: sole trader, partnership or company?
- Where do you register, and which tax numbers do you need?
- Which sales tax rate applies to memberships, classes and personal training?
- Which invoicing rules apply? Some countries require certified invoicing software.
- Do you need to register as an employer before hiring?
3. The people who coach
Some countries regulate who can run a fitness facility or coach in one. Portugal, for example, requires every fitness facility to have a technical lead with a professional licence, and coaches with their own licence. Other countries leave it to the market and to insurers.
- Does the law require a licensed technical lead or head coach?
- Do coaches need a national licence, beyond brand certificates?
- Does your insurer require specific qualifications or first aid training?
- Are your coaches employees or contractors, and what does that change?
4. Insurance
- Public liability: injury to members and visitors.
- Professional liability: claims about coaching advice.
- Property and contents: equipment, fit-out, theft, water damage.
- Member accident cover, where the law requires it. Portugal does, for example.
- Employer's liability or workers' compensation, if you employ staff.
- Exclusions: check each movement you teach, from Olympic lifting to outdoor runs.
5. Membership terms and waivers
Your membership terms are a consumer contract, and consumer law decides what they can say. Write them in plain language, and have a lawyer check them against local rules.
- Price, what it includes, how it renews and how to cancel.
- Notice periods, pauses, refunds, and what happens if the gym closes temporarily.
- Cooling-off rights for memberships bought online. In the EU, the general period for distance service contracts is 14 days, with exceptions.
- Any rules on automatic renewal or minimum terms in your country.
- Booking rules: cancellation window, no-shows, waitlist.
A waiver records what a member declared and that they were told what the training involves. In some countries it cannot exclude liability for injury caused by negligence. Treat it as a record, not a shield, and ask a lawyer what it can and cannot do where you are.
6. Data protection
A gym holds personal data, and often health data from waivers and intake forms. In the EU, the GDPR treats health data as a special category under Article 9. It also requires a written contract with any software provider that processes data for you, under Article 28.
- What do you collect, and why do you need each field?
- Who on the team can see health information?
- How long do you keep data after someone leaves?
- Do you have consent to send marketing messages?
- Do your software providers have a data processing agreement with you?
7. Music
Playing music in classes can count as a public performance. Check whether your streaming service's terms allow use in a business. Some countries license songwriters and performers separately: Portugal, for example, has one licence for authors and another for producers and artists. Ask which ones apply to a gym where you are.
8. Notices and records
- Prices displayed the way consumer law requires, including taxes where it says so.
- Opening hours, house rules and safety procedures on display.
- A complaints procedure, and any official complaints book your country requires.
- Emergency information: nearest phone, emergency number, first aid kit location.
- An equipment maintenance log and an incident log.
- Proof of insurance, where the law requires it to be displayed.
Safety on the training floor
Much of what keeps members safe is not a licence but a habit. Write these down before opening, so every coach does them the same way:
- A first aid kit in a known place, and coaches trained to use it.
- An emergency procedure: who calls for help, who stays with the injured person, who meets the ambulance.
- An incident log, filled in the same day, with what happened and what was done.
- Equipment checks before classes: collars, ropes, rig bolts, rower chains.
- A health question at intake, read by the coach before the first class.
Accessibility
Ask the authority which accessibility rules apply to a building open to the public: step-free entrance, an accessible toilet, door widths. It is cheaper to plan during the fit-out than to change afterwards.
When to start each item
| Weeks before opening | Legal work |
|---|---|
| 12 or more | Check permitted use with the authority, before signing the lease. |
| 10 | Register the business. Ask the accountant about tax and invoicing. |
| 8 | Check staff qualification rules. Start insurance quotes. |
| 6 | Lawyer reviews membership terms, waiver and privacy notice. |
| 4 | Music licences. Opening permit, if your area requires one. |
| 2 | Insurance in force. Notices printed and on the wall. |

Half this list is paper on a wall. It costs almost nothing, and it is the first thing an inspector sees.
If an inspector visits
Keep one folder, paper or digital, that anyone on the team can hand over in a minute:
- Permits for the building and the business.
- The insurance certificate, in force.
- Coaches' qualifications and any licences the law requires.
- House rules, safety procedures and the emergency plan.
- Equipment maintenance and incident logs.
- Music licences.
An example: what Portugal requires
To show how specific the rules can get, Portugal's Lei n.º 39/2012 requires every fitness facility to have at least one licensed technical lead and licensed coaches. It also requires accident insurance for people who train there, with a notice saying it exists. A set of house rules and an operations manual must be on display. Your country may require none of this, or more.
With Rummo
On paid plans, waivers are digital. Each person signs on their phone before their first class, and the signature is stored on their profile with the date. Roles and permissions decide who on your team sees what.
On paid plans, the waiver is digital and stays on each member’s profile. Member management
Frequently asked
- What licences do I need to open a gym?
- It depends on your country and city. Expect questions about the building's permitted use and business registration, plus insurance and consumer rules. Some add fitness-specific rules, such as licensed technical leads or coaches.
- Do gym coaches need a licence?
- In some countries, yes. Portugal, for example, requires a national licence to coach in a fitness facility. Elsewhere, brand certificates and insurer requirements are what count. Check locally.
- Is a waiver enough to protect my gym?
- Not on its own. In some countries a waiver cannot exclude liability for injury caused by negligence. It records what the member declared, and insurance and safe practice do the protecting.
- Do I need a music licence for a gym?
- Often, if music plays in classes or common areas. Check your streaming service's terms for business use, and ask the collecting societies in your country.
- Can members cancel a membership bought online?
- In the EU, consumers generally have 14 days to withdraw from a service contract made at a distance, with exceptions. Other countries have their own rules. Have a lawyer check your terms.
- What data protection rules apply to a gym?
- In the EU, the GDPR. Health data from waivers is a special category, access must be restricted, and software providers need a written processing agreement. Other regions have their own privacy laws.
- Do I need a lawyer to open a gym?
- For the lease, the membership terms and the waiver, a lawyer pays for themselves. One review before opening costs less than one dispute after it.
