It's important to pay attention to a few things when searching for a home to purchase.

There is a gross dependent area for each property. To better comprehend the division and arrangement of the property, it is crucial to be aware of this.


After all, what is a property's gross area dependant on it? What are the subjects covered by it? What role does the gross area play in a property purchase?


Discover how the dependent gross area may affect your purchase by reading the rest of this article.


What is gross dependent area?

The gross area dependent on a property is defined by the Municipal Property Tax Code (CIMI) as all areas used exclusively by the property owner, even if they are located outside the home. As a result, several zones might be taken into consideration.


What are the gross dependent areas of a property?

Dependent gross areas are parts of a property that have direct access to:

  • basement or attic;

  • garage;

  • balcony;

  • other storage areas.


Porches and shed areas are not classified because they are open spaces, hence they are not included.


PLEASE NOTE: Depending on their intrinsic qualities, the aforementioned places may also be regarded as gross private zones.


It is vital to distinguish between the concepts of gross area dependent and gross private area because there are various areas that could cause some confusion regarding its classification.


How do dependent, private, and usable gross areas differ from one another?

The exclusive areas that are used by the owner and are located outside the property make up the gross dependent area.


The boundaries of the property or fraction are defined by the gross private area, which is made up of the entire surface, taking into consideration the outside perimeter and the wall axes.


According to the previous criteria, it can still be challenging in actuality to categorize and separate these two categories. Due to this, we provide some examples:


First example: Balconies are regarded as gross dependent areas if they are covered but open. If they are closed then they are considered private gross areas.


Second example: The pantry, if this is situated on the balcony and is open and without a marquee it is considered an accessory and considered to be part of the gross dependent area. If the access to the pantry is within the property it is considered part of the gross private area.


The definition of the property's useable area must also be understood. This area is defined as "the sum of the areas of all housing compartments, including vestibules, interior circulations, sanitary facilities, storage, other compartments of similar function, and cabinets in the walls, and is moved by the interior perimeter of the walls that limit the fire, counting up to 30 cm, interior walls, partitions, and ducts".


Now that you have made a distinction between the various typologies, it is crucial to comprehend the legal implications of gross dependent area for a property and how they may affect your purchase.


What is the legal impact that the gross dependent area of a property constitutes on the purchase?

The gross area of a building's construction is made up of the total of its private and dependent gross areas.


In turn, Decree-Law No. 287/2003, Article 40, addresses the gross area dependent on a property. The Municipal Property Tax Code classifies this (CIMI).


Nevertheless, in order to complete computations for the Tax on Onerous Transfers (IMT), Municipal Property Tax (IMI), Additional Municipal Property Tax (AIMI), and Stamp Duty, it is crucial to determine the gross dependent area.


As a result, the calculations must take the gross dependent area into account.


What is the importance of knowing information about gross dependent area, when buying a property?

It is crucial to understand the gross area reliant on a property because it might directly affect, as in this instance, the amount due from IMI. This is so that the Property Asset Value (IPV), which is crucial for determining the annual amount payable of IMI, which will be the buyer to handle the payment, in the finances, can be calculated. The gross dependent area is inserted into the gross area of the construction, and the latter will use it.


It is also crucial to remember that the urban building book also contains all the information including the gross area of the property. You can get this information in your local finance office if you need it.
