How to calculate the living area of American houses?

There are many families who immigrate to the United States now, and most of them want to do so by immigrating to the United States. How big a house to buy? What about the living space of American houses? Let me introduce you.

The size of the house, whether it is an independent villa or a high-rise apartment, is the most concerned issue for every property buyer. Generally speaking, there are two types of house area:

One is the building area, which refers to the above-ground and underground parts (basements) of the whole building.

The second is living space, which refers to the area suitable for human life when the builder designs a new house with temperature regulation function (air conditioning or heating or both). Of course, the buyer later rebuilt it himself.

According to convention and agreement, the area of the house we are talking about refers to the living area, not the building area. For example:

When building a new house, the balcony is generally not equipped with air conditioning or heating, so the area of the balcony is not included in the living area, but belongs to the construction area.

The garage is the same, because cars are not afraid of freezing and heating, so there is no need to install air conditioning or heating in the garage, and the area of the garage can not be counted as living area.

Basements are common in America, especially in the northeast. The water heater, heating system, air conditioning system and water supply and drainage system of the house are all concentrated in the basement, and noise, waste gas and gases harmful to human body are not suitable for normal life of human beings. Most basements will not be heated and cooled according to the installation, and they should not be counted in the living area. However, we often hear that many China people lived in the basement when they first arrived in new york because they had no money. It's true, because the rent in new york is very expensive, and many people with low incomes live in basements, because the rent in basements is the cheapest. But homeowners who can afford a house or people with normal income rarely live in the basement, so even if the basement is equipped with heating, most people don't think the basement is a living area.

In addition, from the perspective of safety, many municipal governments stipulate that rooms where people live must have large enough windows, so that in case of fire, people inside can escape from the windows or firefighters can go in from the windows to save people. Therefore, attention should be paid to any additional construction, reconstruction and rental purposes, otherwise, in case of fire, the consequences will be unimaginable because there is no escape window in the tenant's bedroom.
