ᐅ Is it possible to leave a newly built apartment unoccupied without causing mold?

Hello, we are currently buying a new apartment in Berlin, which should be ready by early 2020. However, we won’t move in right away because I still work in another city. We will probably move in only in 2021. We thought that was actually a good thing. This way, we can take our time to choose a nice kitchen, maybe install built-in wardrobes, etc.

Now I am reading everywhere that new buildings tend to be damp and that you have to ventilate and heat quite carefully to avoid mold. The thing is: we don’t live in Berlin! Of course, we will visit every few months and can ventilate then. But for the rest of the time, the apartment will be empty and the windows will be closed. Is that a big problem?

Heating shouldn’t be a problem; you can adjust it accordingly.
Heated rooms without ventilation accelerate mold growth.

In a new building, even without residents, several liters of water per day should accumulate. This moisture needs to be removed through ventilation!

You could ask the building maintenance service, which the new property management will hire, to at least air the apartment briefly once a day.

Alternatively: Use a drying unit with a hygrometer or a timer control and have the tank emptied directly into the drain.

That’s how I would do it. Devices with a hose cost around 200€. Additionally, monitor temperature and humidity online and establish an emergency contact in case something goes wrong. It would still be a good idea to ventilate occasionally to deal with other emissions.

When quoting someone, it’s not good practice to only cite isolated fragments. In my post, I stated that both are important.

I didn’t quote you because I wanted to reply to you, but to address my comment to the OP.

Sorry if you misunderstood and took it personally.
