Measurement of the total area of ​​an apartment

The total area of ​​an apartment is one of the most important characteristics when buying a living space. By law, the contract must contain accurate and complete data about the apartment (including the total area), which becomes the property of the buyer.

There are several values ​​of the indication of the area in the contract: design area; the final total area obtained from the results of measurements by the BTI (or another cadastral service); and the area identified by the buyer himself. Using the square footage calculator, you can easily get the calculation of the measurement of the apartment. 

While measuring the apartment slope, by getting the help of a slope intercept form calculator, you can get the calculation of all your measurements.


Why do you need an area measurement?

Because the final area may differ from the projected area. Depending on the terms of the contract, there are different options for solving the problem.

measurement of an building

The draft agreement should contain specific provisions defining actions in case of disagreements in assessing the footage of an apartment. If the total area of ​​the apartment, based on the measurements of the BTI, really turns out to be less than the agreed one, then the developer in most cases is obliged to return part of the money paid for the apartment.

The same thing works in the opposite direction – the final area may be larger than the design area. In this case, the buyer will have to compensate for the difference. It is also possible to apply other conditions, such as the permissible difference from the design value, when within the established “corridor” no one owes anyone.

Or, for example, the design area is final and no recalculations are provided.


How to measure the area correctly?

In order to determine the actual area, it is not trivial, it is worth attracting professionals. Of course, you can do it yourself. But in this case, it will be more difficult for you to prove your case in case of possible disagreements.

While experienced specialists will draw up a measurement plan for your apartment and prepare the necessary documents.

If you are still going to measure yourself, we have prepared detailed instructions for you.


Fundamental rules

  • Measure with a laser rangefinder (laser tape measure)
  • Evaluate and calculate auxiliary premises (loggia, balcony, terrace) and apply the appropriate reduction factors to them.
  • Exclude from the results obtained in the areas of technical mines, plumbing boxes, utilities (ventilation, water supply, and sewerage pipes).

Before measuring, prepare a detailed plan of the apartment, print it out, take a tablet with you. It is more convenient to start from left to right at the front door. Keep the rangefinder strictly parallel to the floor or at right angles to the wall, about 1m from the floor.


Measurement of rooms of complex shape

Break down all complex shapes into simple ones. On the printed plan, mark the resulting squares and rectangles with a dotted line.

Divide the oval room into simple shapes in the form of triangles. The remaining uncounted parts outside the triangles will have a minimal effect on the final result, they can be attributed to the error.

Count the areas of all simple shapes in one room and add or subtract the resulting values. And so with every room.


How to measure auxiliary rooms?

By law, the total area of ​​the premises consists of the sum of the areas of residential and non-residential premises. 

For auxiliary premises, such as a balcony, loggia, veranda, terraces, etc., reduction factors should apply: for loggias – 0.5; next, for balconies and terraces – 0.3; more, for verandas – 1.0. Alas, some developers ignore these rules and may count auxiliary premises with a factor of 1.

Determine exactly whether you have a balcony or a loggia. A distinctive feature of the balcony is a protrusion outside the building facade; near the loggia – the presence of at least one side of the main wall.

Keep in mind that if you have an apartment, then documented – this is a non-residential premise, and the use of auxiliary coefficients will be irrelevant.


Important nuances

If the premises in the apartment are perfectly rectangular, then the measurement accuracy will be high. If the walls are not parallel to each other, then the values ​​will not be entirely correct. Take measurements on all sides of the room comparing the differences.

Window openings (if they are not from floor to ceiling), openings of balcony blocks, and openings of door frames cannot measure. Openings (arched or rectangular) between rooms less than 2m wide are also you can not include in the total area.

The measurement of the area of ​​the balconies is from the surface of the outer wall to the balcony railing. The area of ​​the loggia is measured in the same way – to the inner surface of the enclosing glass structure

In the course of finishing work, internal walls and partitions are plastered, and this affects the final values. It is necessary to figure out at what stage the BTI measurements were made. It is also necessary to find out how this is reflected, and whether it is reflected at all.

The  contract must stipulate the arrangement of internal partitions, their location on the floor plan, as well as the material from which they are made, and the thickness

Make sure that the location of the interior partitions in the apartment is in place and corresponds to how they really should arrange according to the plan of the premises.


What to do when you detect an area discrepancy?

Most likely, the deviations between the results obtained and the BTI data will be insignificant. But determining the importance of such deviations is a purely individual matter.

Formally, a deviation of 0.1 m2 is already a reason for filing a claim. It all depends on the perception and attitude of the shareholder himself. Some are ready to forgive and 0.5, just to call in as soon as possible, some will stand their ground even for 0.1.

First of all, you need to contact the developer with a claim. In the claim, indicate the requirement to re-measure the area with the involvement of a cadastral engineer (representative of the BTI). 

Further, with a positive reaction, you can offer the developer a solution to the problem – return to the buyer part of the price paid for the apartment. For the return amount, you need to determine yourself, in accordance with the terms of the contract and the cost of 1 m2 of housing. If the developer has ignored the primary claim of the shareholder, then it is already worth doing an examination and submitting a pre-trial claim.

Based on the results of the consideration, you will need to decide whether it is worth starting a trial with the developer or not. In the first case, the court will determine the need for an independent forensic examination and make a decision based on the results obtained.
