How much does a building condition report cost?

The price depends on the property type and size. A condition report for a flat typically starts from NOK 8,000. Detached houses cost more. Contact us for an accurate estimate.

How long does a survey take?

A typical survey takes between two and four hours, depending on the property's size, age and condition. You receive the report within five working days.

Is drilling in wet rooms mandatory?

When wet rooms are inspected, inspection openings may be required from an adjacent room to carry out moisture measurement. The opening is made with a hole saw of minimum 73 mm and sealed with a white cover after the inspection.

What is the difference between TG2 and TG3?

TG2 indicates significant deviations that should be rectified. TG3 indicates serious deviations with risk of damage or loss of function. Both grades trigger further investigation and are described in detail in the report.

Is a condition report required when selling?

Yes. Following changes to the Norwegian Sale of Property Act (avhendingsloven) in 2022, a condition report is in practice necessary when selling residential property. Without one, the seller has weaker protection against claims from the buyer.

What is inspected in a building condition report?

The surveyor examines the property systematically. Every building element is assessed and documented with condition grades from TG0 to TG3 (tilstandsgrad 0 to 3).

Roof and facade — Roofing material, flashings, cladding and sealing around windows.
Wet rooms — Moisture measurement, inspection openings where relevant, and drain condition.
Basement and crawl space — Moisture, drainage conditions and potential radon.
Electrical installation — Visual assessment and inspection of the consumer unit.
Interior — Floors, walls, ceilings, windows and doors.
Exterior — Drainage, ground slope and external structures.

Condition grades: TG0 to TG3

Each building element receives a condition grade (tilstandsgrad) indicating the severity of any deviation from expected condition.

TG0 — No deviations. The element is in good condition.
TG1 — Minor deviations. Normal wear that does not require action.
TG2 — Significant deviations. Should be rectified to prevent consequential damage.
TG3 — Serious deviations. Requires immediate action or further investigation.

Grades TG2 and TG3 trigger a cost estimate in the report. This gives the buyer a realistic picture of what work is needed.

Mandatory drilling in wet rooms

Drilling in wet room wall to check waterproof membrane — Inspection openings from adjacent rooms can reveal signs of moisture in the construction.

The Norwegian regulations on safer property sales may require inspection openings for wet rooms where relevant. The opening is normally made from an adjacent room to carry out moisture measurement in the construction behind the wet room. A hole saw with a minimum diameter of 73 mm is used, and the opening is sealed after inspection.

Many moisture problems are only discovered through drilling. Without this check, hidden damage can remain undetected until it becomes far more expensive to repair.

The regulatory framework

The Norwegian regulations on safer property sales (forskrift til avhendingslova) define how building condition reports must be carried out, what must be documented, and how condition grades are assigned. NS 3600 serves as the underlying technical standard. Together they ensure consistency and quality across all reports, regardless of who carries out the survey.
