A tourist-use property in Spain must meet technical requirements that go beyond having a bed and a bathroom. Each autonomous community demands specific conditions for habitability, equipment, climate control, safety, and documentation. Failing to meet them can prevent you from obtaining a license or result in penalties during an inspection.

Many owners focus on getting the license and publishing their listing, but overlook the technical requirements their autonomous community demands. And they're not optional: an inspection can verify that your property meets minimum conditions, and if it doesn't, the consequence can range from a fine to license revocation.

This guide covers the technical requirements common to most autonomous communities and highlights the most relevant particularities of each territory.

Requirements common to all communities

Although each autonomous community has its own regulations, there's a set of requirements that appear in virtually all of them:

Habitability certificate or first occupancy license

This is the prerequisite for everything else. The property must have a valid habitability certificate (or first occupancy license, depending on your community's terminology). This document certifies that the property meets minimum conditions for habitation: surface area, ventilation, lighting, basic installations.

Without this document, you cannot obtain a tourist license in most communities.

How to get it: apply at your town hall or your autonomous community's housing department. If the property is new construction, it usually comes with the first occupancy license. If it's older, you may need a technical inspection.

Minimum surface area

Most communities require a minimum surface area per property and per room:

Space	Typical minimum area
Complete property	25-40 m² (varies by region)
Double bedroom	10-12 m²
Single bedroom	6-8 m²
Living-dining room	14-18 m²
Kitchen	5-7 m² (or integrated into living room)
Bathroom	3-4 m²

These figures are indicative. Check your community's specific regulations.

Natural ventilation and lighting

All main rooms (bedrooms and living room) must have natural ventilation and direct natural light from the exterior. Interior rooms without windows are not accepted as guest bedrooms.

Bathrooms may have forced ventilation (extractor fan) if they don't have an exterior window, but this varies by community.

Hot water

The property must have hot water in the kitchen and bathroom. It seems obvious, but it's an explicit requirement in the regulations and is verified during inspections.

Mandatory equipment

Bedrooms

Minimum equipment requirements for each bedroom typically include:

Bed with mattress in good condition (minimum dimensions by type: single 90×190 cm, double 135×190 cm)
Complete bed linen: sheets, pillows, pillowcases, blanket or duvet
Wardrobe or storage space with hangers
Bedside table or equivalent surface
Individual lighting (bedside lamp or wall sconce)
Blinds, curtains, or blackout system

Some communities specify the minimum number of hangers (usually 3-5 per person) or require a mirror in the bedroom.

Bathroom

The bathroom must have:

Sink with mirror
Toilet
Shower or bathtub with screen or curtain
Towels (minimum 2 per guest: body and hand)
Soap or shower gel
Toilet paper
Waste bin
Power outlet near the mirror (for hairdryer, shaver, etc.)

Several communities require at least one full bathroom per 4 guest places. If your property has capacity for 6 people, you'll need 2 bathrooms.

Kitchen

The kitchen must be equipped with:

Refrigerator with freezer
Stovetop or cooktop (minimum 2 burners)
Oven or microwave (some communities accept microwave only)
Sink with hot and cold water
Basic kitchenware: plates, glasses, cutlery, frying pan, pot, coffee maker (in sufficient quantity for authorized places)
Basic cleaning products
Trash bin

Some communities also require a toaster, kettle, or coffee maker as minimum equipment.

Living-dining room

Table and chairs for the number of authorized places
Sofa or sufficient seating
Television (not mandatory in all communities, but in most)

Climate control: heating and air conditioning

This is one of the areas where requirements vary most by autonomous community and climate zone.

Heating

Virtually all communities require heating. The type may vary:

Central or individual heating (radiators, underfloor heating)
Heat pumps (air conditioning with heating function)
Electric or gas heaters (accepted in some communities as a minimum solution)

In coastal areas with mild winters, some communities are more flexible. In interior or mountain areas, the requirement is strict.

Air conditioning

Not all communities explicitly require it, but in practice:

Andalusia, Murcia, Valencia, and the Balearic Islands require it or consider it essential due to summer temperatures
In Madrid, Catalonia, and other interior communities, it's highly recommended though not always mandatory
In the Canary Islands, natural ventilation is usually sufficient in many areas

Practical tip: even if your community doesn't require it, not having air conditioning in an area with hot summers will destroy your reviews and occupancy. It's an investment that pays for itself.

Internet connection (wifi)

Wifi has become an almost universal requirement:

Most communities explicitly require it in their regulations
Those that don't legally require it consider it an essential market standard
It must be broadband with sufficient speed for streaming and video calls

Recommended speed: minimum 50 Mbps download. If your property has capacity for 6+ people, consider 100 Mbps or more. Guests work remotely, make video calls, and stream simultaneously.

Tip: include connection instructions (network name and password) in a visible place in the property and in the welcome message.

Safety

Mandatory requirements in most communities

Security lock on the main door
First aid kit with basic supplies (bandages, antiseptic, gauze, scissors)
Fire extinguisher (mandatory in some communities; recommended in all)
Smoke detector (mandatory in several communities; highly recommended)
Emergency information visible: emergency phone numbers (112), nearest hospital, police station

Electrical and gas safety

Electrical installation with grounding and circuit breaker
Gas installation inspection (if applicable) with valid certificate
Gas water heater with adequate ventilation (never in enclosed spaces without ventilation)

Swimming pool (if applicable)

If the property has a private pool:

Perimeter fencing with safety lock (mandatory in many communities)
Depth signage
Basic rescue equipment (life ring or pole)
Visible usage rules

Mandatory documentation in the property

You must have available in the property (physically or digitally):

Complaint forms

Mandatory in all autonomous communities. They must be available to the guest upon request. You can have them in physical format or indicate how to access them electronically.

Tourist information

Many communities require you to provide information about:

Local tourist resources
Public transportation
Emergency services (hospital, pharmacy, police)
Useful phone numbers

Property instructions

Not always an explicit legal requirement, but a good practice that prevents problems:

Appliance operation
Air conditioning/heating instructions
Homeowners' association rules (noise hours, pool use, etc.)
Waste management (recycling)
Wifi password

Tourist registration number

Your registration number must be visible on:

Your listing on platforms
The property entrance (some communities require it on an exterior plaque)
Documentation you provide to guests

Accessibility

Accessibility regulations vary significantly:

Tourist properties on the ground floor or with elevator don't usually have additional accessibility requirements
Some communities require a percentage of tourist properties from the same owner to be accessible
If your property is accessible, highlight it in your listing — it's a competitive differentiator

Quick verification checklist

Before applying for your license, verify that your property meets these minimums:

Requirement	✓
Valid habitability certificate	☐
Minimum surface area per room	☐
Natural ventilation and lighting in bedrooms	☐
Hot water in kitchen and bathroom	☐
Heating	☐
Air conditioning (if your region requires it)	☐
Broadband wifi	☐
Complete kitchen equipment	☐
Bed linen and towels	☐
Security lock	☐
First aid kit	☐

What happens if you don't meet the requirements?

The consequences depend on severity and your autonomous community:

Inspection with minor deficiencies: deadline to fix them (usually 1-3 months)
Serious deficiencies: temporary license suspension until corrected
Repeated non-compliance: license revocation and fine
Operating without meeting minimum requirements: fines from €3,000 to €30,000 depending on community and severity

How Autoregistro fits in

Autoregistro focuses on guest registration and communication with authorities, not on verifying technical requirements. But by correctly managing the documentary and registration side — which is another mandatory requirement — it lets you focus on keeping the property in shape. An owner who has automated guest registration has more time and less stress to ensure that equipment, cleaning, and maintenance meet the standards the regulations demand.
