Overall assessment

The apartment is from 2016 and has 2 critical and 2 serious findings. Expect to spend 29,000 to 77,000 DKK on repairs, and keep a buffer for what still needs checking.

  • The bathroom floor drain is not sealed to the membrane.
  • The apartment is 88 m² in BBR but 92 m² in the sales material.
  • Common parts such as the roof and facade are not part of the report.
  • Expect 25,000 to 72,000 DKK for the critical and serious findings.

Do this before you sign

  1. Ask the seller to fix the fuse board before handover.
  2. Have a plumber assess the floor drain, and ask the owners' association about past damp damage.
  3. Read the owners' association's maintenance plan and latest minutes.

What the report does not cover

The inspection is visual. These things were not examined in your apartment. Here is what you can do, and roughly what it costs:

  • Radon in indoor air

    Why Not measured in the inspection

    Check Radon measurement over 2 months, 500 to 1,000 DKK

  • Common building parts

    Why Roof, facade, stairwell and drains are not fully covered by the report for an apartment.

    Next step The owners' association's maintenance plan and budget

Public data for the address

Looked up for the plot. Every source shows its date.

  • Soil contaminationNo remarksNot mapped

    The plot is not mapped as V1 (possible contamination) or V2 (documented contamination).

    Source: Danmarks Miljøportal, 12 October 2026

  • Zone statusFor informationUrban zone

    The home is in an urban zone. That is normal in towns and gives the fewest restrictions.

    Source: Plandata.dk, 12 October 2026

  • Local plan and zoneFor informationLocal plan 310

    Teglværkshavnen (fictional). The plan sets limits on what you may build and change. Read it before planning an extension, carport or sunroom.

  • FloodingNo remarksNot in a mapped risk area

    The address is not in Kystdirektoratet's mapped areas for storm surge and river flooding. Cloudbursts are not mapped per address: see the municipality's climate adaptation map.

    Source: Kystdirektoratet, 12 October 2026

  • RadonFor informationLow risk above ground floor

    Radon comes from the ground, so apartments above ground floor rarely have problems. For a ground floor or basement apartment, a measurement (500 to 1,300 DKK) is worth considering.

  • Energy labelNo remarksEnergy label B

    Valid until 22 June 2033. Read the label's improvement proposals: they show where the heating bill can be cut.

Questions for the seller and agent

Based on your findings and the address data. Copy them into an email to the agent.

  1. Will you fix the faults in the fuse board before handover?
  2. Can the price be adjusted for the roof and drains if the inspections show damage?
  3. Does the owners' association have a maintenance plan, and what is planned for the next 5 years?
  4. Have special levies for the roof or facade been adopted or discussed?
  5. Does the owners' association know of damp damage from bathrooms in the stairwell?

Home buyer's insurance

Home buyer's insurance (ejerskifteforsikring) usually does not cover damage already listed in the condition report or the electrical report. The findings above are therefore usually your own cost, whatever insurance you take. Matters not examined may be covered depending on the policy. Read the policy terms and ask the insurer before you sign.

Method and limitations

Findings are read from your reports with AI and shown with the report's own text. Grades are read from the report and mapped to one scale by fixed rules. Verdict, counts and amounts are computed by code, not by AI. Cost estimates build on Tjekhuset's price table and are ranges, not quotes. Public data comes from Datafordeler (DAR, MAT, BBR), Danmarks Miljøportal, Plandata and Kystdirektoratet, dated at every item. Tjekhuset is not building or legal advice and not a recommendation to buy or not buy.
