Can the Co-op Board in Swedish Apartment Buildings Veto Sublets?

Unfortunately, the co-op board (bostadsrättsföreningen) still has the right to veto your sublet unless you can demonstrate valid reasons for your sublet, like working in another city. There was much hope, and certain misconception on the market, that the law that was passed 2014 would prevent the boards from not allowing sublets. 

The issue was tried in a highly publicized case in the rent tribune (hyresnämnden) after the new law of 2014. The case was an owner on Södermalm that continuously sublet their apartment on Airbnb. The rent tribune ruled that this would be considered a hotel type of operation and that the co-op board has a valid reason not approving such sublets. Unfortunately, this ruling gave a lot of other boards more confidence to veto sublets and we now see quite a bit of cases going up in the rent tribune and the owner losing their case.
