Why is it important to know the regulations for storage rooms?
Having additional space to store personal belongings, furniture or business equipment has become a common need. However, before renting or using one, it is essential to know the regulations on storage rooms in force in Spain.
This regulation regulates both the construction and use of storage rooms and the conditions of safety, ventilation, access and rental of these spaces. Complying with it not only avoids penalties, but also guarantees the protection of people and stored goods.
Storage room regulations: general requirements
Storage room regulations are mainly regulated by the Technical Building Code (CTE) and by various municipal ordinances, which may vary depending on the locality. Below, we summarize the most important aspects that these spaces must meet.
Ventilation and health conditions
Every storage room must have adequate ventilation, either natural or forced, to prevent the accumulation of moisture or gases. In the case of being in a basement, a mechanical ventilation system is required to ensure air renewal.
In addition, the regulations on storage rooms establish that they cannot be used for housing or resting, and must be kept clean and dry to prevent the proliferation of mould or pests.
Building materials and fire resistance
Storage room regulations require the use of fireproof or fire-resistant materials, especially on walls and doors.
According to the CTE, storage compartments must guarantee a minimum fire resistance of 90 minutes (EI-90), depending on the building and its use. Doors must be fireproof and, in many cases, have automatic locks to prevent the spread of fires.
Signage and accessibility
Each storage room must be numbered and signposted correctly. In residential or public buildings, it is mandatory to indicate the location of emergency exits and fire extinguishers.
In terms of accessibility, the regulations on storage rooms indicate that corridors and accesses must allow the passage of people with reduced mobility, in accordance with the Basic Document on Safety of Use and Accessibility (DB-SUA) of the CTE.
Storage room rental regulations: rights and obligations
In addition to the technical requirements, there are legal aspects related to the rental of storage rooms that should be known. The regulations for renting storage units are governed by the Civil Code and, in some cases, by the Urban Leases Law (LAU).
Rental Agreement
The contract for a storage room is not the same as that for a home.
The regulations on the rental of storage rooms establish that this type of contract is considered a lease for use other than housing. This means that the landlord and tenant can freely agree on the duration, rent and conditions of use, as long as they do not contradict the law.
It is essential that the contract specifies:
- Data of the parties.
- Exact description of the storage room (location, square meters, number, etc.).
- Rental price and payment method.
- Duration of the contract and possibility of renewal.
- Conditions of use and access.
- Liability for damage or loss.
Liability and insurance
The regulations on storage rooms do not require insurance, but it is highly recommended.
The tenant is usually responsible for the stored goods, while the owner must ensure that the storage unit meets the appropriate safety and maintenance conditions.
In professional centres such as Metrecubic, storage rooms have surveillance, alarm and access control systems, as well as optional insurance for your belongings.
Permitted and prohibited use
Storage regulations prohibit the storage of flammable, explosive or dangerous products, such as fuels, paints or gases.
It is also not allowed to use the storage room as a workspace, bedroom or commercial premises. Its function is strictly the storage of personal or business property.
Regulations on storage rooms in neighbourhood communities
If the storage room is located in a residential building, the Horizontal Property Law (LPH) also comes into play.
In this case, the storage rooms are part of the private or common elements of the property, and their use is subject to the internal rules of the community.
Some key points:
- Works that alter the structure or façade of the building may not be carried out.
- The rules of safety and coexistence must be respected.
- In the case of communal storage rooms, the community can establish access or sharing rules.
Penalties for failing to comply with storage room regulations
Failure to comply with the regulations may lead to fines or administrative sanctions, especially in cases of:
- Storage of hazardous materials.
- Lack of ventilation or safety measures.
- Improper use (home, workshop or leisure venue).
Therefore, both owners and users must ensure that the space complies with the regulations on storage rooms before putting it into use.

Knowing the storage room regulations and rental conditions is not only a legal issue, but also a matter of security and peace of mind.
