"Habitability" or “The habitable” must provide shelter and care to the human being, since habitation, according to M. Heidegger (1889 – 1976), is the fundamental feature of man's being.[7]​.

In the conference “Build, inhabit, think” (1951),[7] Heidegger places us in a truth that would seem unquestionable: “In inhabiting we arrive, so it seems, only by means of building” (Heidegger, 1951), building has as its goal inhabiting. However, Heidegger warns us that not all constructions fulfill the function of being “dwelling.” We have the case of constructions that are not housing, such as the highway for the truck driver, the yarn factory for a worker or the power plant run by an engineer, in which they are “at home”, but they do not live there. Living goes beyond buildings. A construction can house man. Man lives in a construction, but dwelling is not living in a place, understanding living as having accommodation.

On the other hand, the constructions that are spoken of that are not homes, are in some way made from inhabiting, since they serve for the habitation of man, with which we cannot affirm that building is what generates inhabiting, but vice versa: "Inhabiting would be in each case the end that all construction pursues" (Heidegger, 1951).

The meaning of “build”, which in Old High German is buan, means to inhabit, which in turn means: to remain, to reside. Now, the word buan does not say that building is only living, but rather it refers to how we should think about the living that it mentions. If we talk about dwelling we are talking about a form of behavior that man carries out. Thus, Heidegger affirms that working itself is already a way of living, since living is not inactivity, we live from our profession, we live when we do business or travel, even when walking we live, thus building or bauen is originally living.

The existential implication of this statement is reflected by stating that originally building and inhabiting were understood in the same way: Bauen, buan, bhu, beo come from the word bin (I am), ich bin, du bist (I am, you are) bis sei (I know). So ich bin or du bist is: I dwell, you dwell. That is, the way men are on earth.

Hence Heidegger affirms the indissoluble identity between being a man and living: “Being a man means: being on earth as a mortal, means: living” (Heidegger, 1951). The ancient word “bauen” means that man is to the extent that he dwells, bauen means at the same time to shelter and care.

Building as shelter and care is not just about producing. In the case of ships and temples that are a product of construction, then we would not be talking about caring, but about erecting. To build as to care in Latin is collere, culture and to build, in the sense of raising buildings, is aedificare in Latin, for Heidegger they are included in the very construction, to inhabit. Thus, building, like living, is being on earth, it is living the “usual”. Living like this is behind the activities of caring and building, they are activities that claim the name of building.

Heidegger says that, in terms of building, although the essential meaning of language has been forgotten, “dwelling testifies to the origin of these meanings” (Heidegger, 1951).

But when understanding what the language says about building we have to:.

1. Building is properly inhabiting.

2. Dwelling is the way mortals are on earth.

3. Building as living unfolds in building that cares – that is, that cares for growth – and in building that erects buildings.

Inquiring again into the essence of Dwelling, the ancient Saxon wuon, and the Gothic wunian, mean the same as the bauen, to remain and reside. But the Wunian Gothic says more clearly the experience of this abiding. Wunian means to be at peace or satisfied, brought to peace and abiding in it. Friede which means peace is the free, das Frye, fry means: “preserved from harm”. Freien (liberating) is properly caring.

Caring is something positive, it is leaving something in its essence. Hence: “The fundamental feature of living is this caring (guarding, watching over), (Heidegger, 1951).

Acoustics

In order to protect people from noise, buildings must guarantee adequate acoustic insulation both between different rooms and with other buildings or with the outside. Sound insulation is measured in decibels (dB) or decibels A (dBA). The insulation requirement varies depending on the use of the building, being higher in homes and hospitals, and lower in offices and shopping centers. It is also common for more insulation to be required in particularly noisy areas: a typical case is specific acoustic regulations in municipalities near an airport.

Thermal insulation

This section is responsible for ensuring that the building is capable of maintaining a comfortable temperature. However, with the rise of the energy crisis "Energy crisis (economy)") and global warming, the priority has shifted towards energy saving, so that buildings can maintain this temperature with minimal energy expenditure.

Healthiness

Health includes the lighting and ventilation of the premises. Depending on the use and dimensions of each room, different levels of sunlight or natural lighting are required, always exceeding the minimum of 10% of the minimum lighting surface, as well as a minimum ventilation capacity.[3]​ As a general rule, in rooms intended for the permanence of people, natural lighting and ventilation are required, and only in places such as toilets, garages or storage rooms is the exclusive use of artificial lighting and ventilation through *shunts "Shunt (architecture)") or methods allowed. mechanics.

Ventilation is also related to protection against humidity, both to prevent the appearance of diseases and to protect the building itself from deterioration. For this reason, the regulations require adequate sealing in windows and walls.

Health also includes the adequate supply of drinking water and domestic hot water,[1]​ as well as the correct channeling and evacuation of wastewater.

Usually, minimum heights are also required in all habitable rooms of the property. In this way, in living rooms the minimum height is 2.20 m, to convert it into a habitable room.

Minimum dimensions

Another section that is included within the habitability conditions is that of the minimum dimensions of the rooms. The regulations require a minimum size for both homes and their different parts (bedrooms, toilets, living room, etc.). Sometimes it is required that the dimensions of common circulations be compatible with accessibility regulations for the disabled, although strictly speaking these are independent regulations.

The minimum dimensions range from the size of the property in general to the different rooms. As a general rule, the home must have a minimum surface area of ​​36 square meters. The minimum size of a single room is 6 square meters, a double room 8 square meters or a double room 10 m².

A minimum number of rooms is also usually required, such as a living room-dining room, a bedroom and a full bathroom. The kitchen must not be independent for the home to be considered habitable, but the installation must be complete.[4]​.

Security

Finally, issues related to safety of use are discussed,[5]​ such as the existence of parapets and railings to prevent falls, electrical current switches, or fire-fighting systems.

We cannot ignore, of course, what is related to the general stability of the construction, the general state of its components such as the general structural system, walls, roof, windows, electrical and gas installations, etc. and in general all parts of the work that ensure its use without risk to its users.

Others

It is common that within the minimum habitability conditions, certain telecommunications services are also required, such as television antenna or telephone pre-installation.[5]​.

The good state of maintenance of the electrical installation and its updating to current regulatory standards is also required to ensure the habitability of a home.[6]​.
