The dripping of air conditioning onto the street: fines of up to one thousand euros

Published on 2026-07-02 | Translated from Spanish

The constant dripping of air conditioning onto the sidewalk is not just a nuisance for pedestrians. In many cities, this practice is prohibited by municipal ordinances and can result in fines of up to 1,000 euros. If the puddle causes a slip or accident, the equipment owner assumes civil liability and all resulting costs. The solution is simple and avoids legal problems.

Technical drain installation: connect it to the downpipe 💧

To avoid penalties, the correct approach is to channel the air conditioner's water into the sewage system. This is achieved by connecting the drain tube to a building downpipe or a drain. If this is not possible, a collection system with a sufficiently sized tank or bucket must be installed and emptied regularly. Failing to do so causes moisture on facades and slip risks on public roads. Maintenance is minimal but mandatory.

The bucket as a high-risk solution for your wallet ⚠️

The bucket option seems easy, but it has a catch. If you forget to empty it, the water ends up on the ground just as before, only delayed. It's like having a time bomb with a musty smell. And if the downstairs neighbor decides to file a lawsuit over the puddle that fell on their head when leaving, you'll have to pay. Better to connect the drain and forget about the problem, or become an amateur plumber with a risk of fines.
