Andalucia's New Space and Safety Laws: Is Your Malaga Rental Legal?

Let us be completely honest. The regional government in Andalucia loves a good paperwork shake-up. If you own a holiday home on the Costa del Sol, you are probably used to the goalposts moving just as you get comfortable.

But the latest update, Decree 31/2024, published in the Boletín Oficial de la Junta de Andalucía (BOJA) on 2 February 2024, is not just minor fine-tuning. It introduces some heavy structural demands. If you are trying to make sense of the holiday rental requirements Malaga 2026 demands, you need to look closely at your property layout right now.

Some of these rules are already active. Others have grace periods that are ticking away. If your property does not comply, you risk losing your tourist licence or facing eye-watering fines.

Here is a straight-talking guide to what has changed, what hurts, and what you need to do.

The 14 Square Metre Rule: Goodbye Sofa Beds

For years, owners of tiny studio apartments could register their properties for four guests by throwing a double sofa bed into the living room. Those days are over.

Under the new decree, any holiday rental must have a minimum of 14 square metres of useful floor space per guest. On top of that, the absolute minimum size for any holiday home is 25 square metres.

If you own a cosy 45-square-metre apartment in the centre of Malaga, your maximum legal capacity is now three people. No matter how comfortable your sofa bed is, you cannot legally advertise for four. Forcing extra guests in is a quick way to get flagged by the authorities.

The Bathroom Headache

This is the rule that is causing the most panic among owners of larger apartments and townhouses. The Junta has introduced strict ratios for bathrooms based on your guest capacity:

• Up to 5 guests: At least 1 bathroom.
• 6 to 8 guests: At least 2 bathrooms.
• 9 or more guests: At least 3 bathrooms.

Think about a classic Spanish three-bedroom apartment with one bathroom. Many owners used to sleep six people there by utilizing every corner. Now, if you only have one bathroom, your maximum capacity is capped at five. To host six, you must install a second bathroom. In a compact apartment, finding the space and getting the plumbing licences for a second bathroom is often physically or financially impossible.

No More Portable AC Units

We all know Malaga summers are brutal. Previously, some owners got away with putting a noisy, portable air conditioning unit in the hallway and calling it a day.

The new rules put an end to this. You must have fixed climate control systems (both cooling for May to September, and heating for October to April) installed in every single bedroom and living area.

These cannot be portable rollers with pipes hanging out of the window. They must be permanent, professional installations. If your community of owners bans external AC compressors on the facade, you have a major problem that you need to resolve with the community board immediately.

When Do These Rules Apply?

If you are registering a brand-new holiday rental, these rules apply to you immediately. Your licence will not be approved if you do not meet them.

For properties that were already registered before February 2024, the Junta granted transitional periods. The deadline to install the fixed heating and cooling systems was February 2025. The timeline for some structural changes, like the physical dimensions and bathroom ratios, remains a point of intense discussion among local real estate lawyers, with some aspects enjoying a longer grace period of up to five years, while others face immediate pressure from local town halls tightening their municipal planning laws.

If you are worried that reducing your guest capacity to meet these rules will ruin your profits, you should run the numbers. You can use the Casa del Sol rental yield calculator to see how adjusting your guest count or upgrading your property affects your actual take-home income.

What Happens If You Ignore the Rules?

Spanish authorities are actively auditing registry listings against land registry (Catastro) data. If your registered capacity does not match the square footage on record, or if a guest reports that your apartment lacks proper cooling, inspectors can and will fine you. Fines under Andalucia's tourism laws are notoriously high, often starting at several thousand euros for minor infractions and climbing rapidly for serious non-compliance.
