What is the minimum, legal size for a dwelling in Spain?   (Part 1)

There has been a norm in Spain since 1944 called “Order of the Ministry of the Interior of 29 February 1944”. That law laid down the minimum conditions to be met by all kinds of homes, regardless of ownership throughout Spain. Believe it or not this legislation is still in force in several autonomous regions (including the Murcia region) where they do not have a particular law which lay out the minimum conditions to be met in the design of any type of home. 

Now that we have 17 regional governments we have 17 different regulations governing the design of a new dwelling. In this article we will analyse the closest to us geographically speaking i.e. the Valencia Regional regulations:

 

The Valencia region

In the Valencia region there is the Order of December the 7th of 2009 from the Ministry of Environment, Water, Urbanism and Housing which approves the conditions of quality design and development.

In the Murcia region there is the law 5/1995 of 7 April, on living conditions in residential buildings which also recommends general guideline for accessibility for the disable. These regulations it promotes the field of accessibility for the disable rather than dealing with the ground of habitability, so in Murcia we still use the Order of the Ministry of the Interior of 29th  of February of 1944.

 

In the Catalan community

 

The Catalan Government approved the October 31, 2012 a decree regulating the living conditions to be met by households and reduced from 40m2 to 36 m2 the minimum area that a dwelling must have for any new construction. This regulation intended to relax the requirements for housing design and adapt to the new economic reality of the country, modifying the decree passed in 2009, which stated that the new homes should have a minimum area of 40 square meters.

 

As a working example let's take the Valencia regulations.

While there may be some slight variations between the laws of other communities and the national dated from 1944, in most cases the limitations in terms of sizes and minimum numbers of rooms are very similar. I must say however that apart from the regulations of the autonomous communities, the national regulations we also have to take into account the municipal and local planning regulations.

Another very important to keep in mind is that when we compare different legislations we have to apply that legislation that is most restrictive.

First we must distinguish whether the building is new construction or rehabilitation. Secondly we will consider if the housing will be adapted to be used by disabled persons. Thirdly, if the use of the building is for business letting, i.e hotel, bed and breakfast etc.

b) Every space or area with a bath or shower is considered a “wet area” for the purposes of applying the Spanish regulations of “Indoor Air Quality” from the Technical Building Code, and the internal finishes must comply with that established in Article. 5 d), of the aforementioned regulations. (This regulation specifies the rules that we have to take into account when ventilation wet rooms)

c) When dwellings have more than one bedroom, one may access to a space for personal hygiene from the circulation spaces of the house.

d) The bathroom and toilet will not be a through access to another room or enclosure.

 

Ceiling heights and spaces between furniture.

1. In houses the minimum headroom is 2.50 m, allowing up to 10% of the total net area with a height of 2.20m. In circulation spaces, bathrooms, toilets and kitchens, the minimum headroom shall be 2.20 m.

2. Every rooms or enclosures should be able to register two types of minimum circles:

a) The circles must be free of obstacles, allowing free movement for the user within the house. These figures can overlap each other, if the functions are grouped in the same enclosure.

b) The figures to typify furniture must allow the proper placement of furniture in the house. These figures cannot overlap with any other figure, being designed each in its specific type of furniture. The doors opening can invade the figure free of obstacles and figures for furniture.
