Swimming Pool Regulations in Spain 2026: Legal Requirements
Building or renovating a swimming pool in Spain requires compliance with a set of legal regulations that govern both the construction process and the conditions for the facility’s use and maintenance. Failure to comply with these regulations can result in consequences ranging from the suspension of construction work to the imposition of significant financial penalties. At ArgPiscinas, we offer you a comprehensive guide to the main legal requirements applicable in 2026.
Royal Decree 742/2013: The Basic Regulation for Public Swimming Pools
Royal Decree 742/2013, dated September 27, which establishes the technical and health criteria for swimming pools, is the national standard for public swimming pools. It regulates aspects such as water quality (free chlorine between 0.5 and 2 mg/L; pH between 7.2 and 7.8; turbidity less than 2 UNF; maximum temperature of 30 degrees C in recreational pools), the structural characteristics of the pools, and filtration systems with maximum water recirculation times based on the type and use of the pool. For private swimming pools intended for single-family use, Royal Decree 742/2013 does not apply directly, although many municipal governments use it as a reference when issuing building permits.
Technical Building Code (CTE)
The CTE applies to swimming pools with regard to their access points, stairs, and perimeter areas. The Basic Document on Safety of Use and Accessibility (DB-SUA) establishes requirements regarding the slip resistance of perimeter flooring, handrails, and protection of openings. For public swimming pools, the DB-SI on Fire Safety also applies with regard to machinery rooms.
Municipal Permits: What You Need
In almost all municipalities, the construction of a swimming pool—even in a single-family home—requires obtaining a building permit in advance. The documentation typically required includes: a technical project signed by an architect or technical architect, a site plan, a descriptive report of the work, and a budget for construction materials. The processing time for the permit typically ranges from 1 to 3 months. In many Andalusian municipalities, it is possible to file a sworn declaration for minor construction work, which significantly reduces the processing time.
Safety Requirements: What You Can’t Do Without
Perimeter fencing: In many municipalities, a perimeter fence is required to prevent unauthorized access to the pool, especially to protect children. The minimum height is usually 1.20 meters. Depth markings: It is mandatory to clearly mark the depth of the pool, especially at the points of maximum and minimum depth. Anti-entrapment system: Since Royal Decree 742/2013 went into effect, all bottom drains must be equipped with approved anti-entrapment grates that prevent people from being sucked in.
Specific Regulations for Andalusia
In the Autonomous Community of Andalusia, in addition to national regulations, Decree 23/1999 of the Regional Government of Andalusia applies, which regulates the health and hygiene conditions of public swimming pools. This decree establishes additional obligations regarding health records, periodic water testing, and reporting to the health authority.
Penalties for Noncompliance
Violations of swimming pool regulations may be classified as minor, serious, or very serious, with penalties ranging from 3,000 euros for minor violations to 600,000 euros for very serious violations in the health sector.
