Usable area and area shortfall in Norway: BRA-i, BRA-e, BRA-b and TBA (2026)

From 1 January 2024, a home in Norway states its usable area with three new measures: BRA-i (internal), BRA-e (external) and BRA-b (glazed). P-rom and S-rom are phased out. If the home is smaller than the seller stated, it is a defect when the deviation is over two percent and at least one square metre. Then you can complain.

Usable area (bruksareal) is the area you can use in the home, measured under the NS 3940 standard. The new breakdown from 2024 makes it clearer what kind of area you are actually paying for, so a storeroom or an enclosed balcony is not mixed in with the living space itself.

What BRA-i, BRA-e, BRA-b and TBA mean

Measure	Meaning	Example
BRA-i	Internal usable area, within the home’s walls	Living room, bedrooms, bathroom, kitchen
BRA-e	External usable area with its own entrance	Outdoor storeroom, cellar storeroom
BRA-b	Glazed usable area	Enclosed balcony or veranda
TBA	Terrace and balcony area, open	Open terrace, open balcony

BRA-i is closest to the old P-rom concept and tells you how much actual living space you get. BRA-e and BRA-b are areas that belong to the home but are not full living rooms. TBA is open outdoor area and does not count in BRA at all.

When you compare two homes, look at BRA-i first. Two flats can both be advertised with the same total area, but one has much of it as a storeroom and enclosed balcony while the other has it as internal living space.

P-rom is phased out

Until 2024 a home was split into primary rooms (P-rom) such as the living room, bedrooms and bathroom, and secondary rooms (S-rom) such as storerooms and technical rooms. From 1 January 2024, both terms were replaced by the BRA breakdown. Older listings, surveys and condition reports may still show P-rom, so it helps to know that BRA-i covers much of the same ground in practice.

Area shortfall: when too little area is a defect

If you find the home is smaller than stated, it can be an area shortfall (arealsvik). Under avhendingslova section 3-3, it is a defect when both of these conditions are met:

• The deviation is greater than two percent of the stated area.
• The deviation is at least one square metre.

An example: a home stated at 70 square metres must be short by more than 1.4 square metres (two percent) and at least one square metre before it counts as a defect. Small measurement inaccuracies fall within the margin, while a genuine deviation gives you grounds to complain.

How to proceed with an area deviation

If both conditions are met, you may be entitled to a price reduction reflecting the value of the missing area. Here is how to secure the case:

1. Have the area re-measured by a professional so you have a documented figure.
2. Complain in writing to the seller within reasonable time after you discover the deviation.
3. Keep the sales prospectus and the condition report, which show the area you were told.

The size of any price reduction is assessed case by case from how much smaller the home is and what that means for its value.

Heimer reads the sales prospectus and pulls out BRA-i, the total price and the monthly cost, so you see what you actually pay per square metre of living space. Paste the listing.
