Setting up a gym is a great business opportunity in an ever-growing sector. However, before opening the doors, you will need to know the legal requirementsobtain the activity licence and make sure to comply with technical regulations.
In addition, there is a key factor that many overlook that can lead to major problems if not taken into account: the acoustics. The noise generated by activities inside the gym, such as music, weights and supervised classes can cause nuisance to neighbours if the right measures are not taken. We explain everything you need to know to open a gym without problems.
Choice of premises and first steps
The first step to opening a gym is to find a place to work out. suitable premises that complies with urban planning and technical regulations. It is important to verify that the location is compatible with this type of activity, as some municipalities have restrictions on where gyms can be installed due to the impact of noise and crowds.
In addition, the premises must meet basic requirements such as accessibility for people with reduced mobility, have a good distribution of space for the different training areas, changing rooms and storage areas, as well as an adequate ventilation system to ensure indoor air quality. It is also important to ensure that the structure of the building can support the weight of the equipment and that it is equipped with fire safety measures.
Installations and technical requirements
A gymnasium requires a number of specific facilities that must comply with technical regulations to ensure its operation.
- Electricity supply: make sure that it is sufficient to cover the consumption of training equipment, air conditioning and lighting. It is advisable to make a study previous to determine the power required.
- Air conditioning and ventilation: Gymnasiums generate heat and humidity due to intense physical activity, so it is essential to have a ventilation system that ensures adequate air circulation. This improves user comfort, prevents moisture build-up and the development of odours or condensation problems.
- Fire protectionFire extinguishers at strategic points, accessible and well-distributed evacuation exits. Depending on the size of the gymnasium and local regulations, smoke detection and fire alarm systems may also be necessary.
Procedures and licences for setting up a gymnasium
One of the most important aspects of opening a gymnasium is to obtain the right activity licence. This permit is mandatory in most cases, as it certifies that the premises comply with the technical, environmental and safety requirements demanded by the regulations. In order to obtain the activity licence, documents must be submitted, such as:
- Technical projectThe following is the result of a engineer or qualified technician, detailing the suitability of the premises.
- Environmental reportif the gymnasium generates noise or emission impacts.
- Security reportincluding fire and evacuation measures.

In some cases, if the premises already have a previous activity licence and do not require major modifications, it is possible to opt for a affidavit instead of a traditional licence. This is quicker, but still requires compliance with all regulations.
In addition to the business licence, the following may be required to operate legally other specific permissions depending on the services offered by the gym, the most common are:
- Health registration: mandatory if the gym offers physiotherapy or nutrition services.
- Liability insurance: protects against possible accidents of clients inside the gymnasium.
- Fire protection authorisations: certification that the premises comply with fire prevention regulations.
- Energy efficiency and electrical safety certificates: to ensure that installations comply with consumer and safety standards.
Acoustics and soundproofing in gymnasiums
One of the biggest challenges when setting up a gymnasium is the noise. The thumping of weights, loud music and the sound of supervised classes can create a nuisance both inside the establishment and in the surrounding area. Ignoring acoustics from the outset can lead to complaints, fines and even the inability to obtain a business licence.
To avoid problems, it is advisable to carry out a acoustic study to determine the level of noise generated and the measures needed to minimise it. Among the most effective solutions are the use of absorbent materials in walls and ceilingsthe installation of special floors to reduce vibration and the implementation of acoustic insulation systems to prevent the propagation of sound to the outside.
Good acoustics not only benefits the neighbours, but also the gym's own customers. A well soundproofed environment improves the user experience, avoids annoying echoes and allows the different areas of the gym to function without interfering with each other.
At PBM Engineering we are specialists in acoustic studies and we can help you comply with the regulations so that your gym can run smoothly from day one.
Considerations for setting up a gym
The process of setting up a gymnasium can take several months, depending on permit processing times, necessary renovations and the installation of essential systems such as air conditioning and soundproofing.
It is important to plan each stage in advance and have the professional support to avoid delays or legal problems. Factors such as the length of administrative procedures, renovation of the premises and installation of technical systems will influence the opening date.
Opening a gym is not just a matter of finding premises and buying exercise equipment. At PBM EngineeringWe accompany you through the entire process for the licensing and implementation of acoustic solutions. If you are thinking of opening a gym, make sure you do it with all the guarantees, both legal and technical.
