What are the minimum safety requirements for house construction?

(Electric, bear, acid, pick-your-poison-)trap behind it.

Is that allowed in Germany?

Otherwise, I can only repeat my post from another thread: Get yourself a dog! Best alarm system and, in the appropriate size, also protection personnel in one!

I (again) only say: Geese!

Is that allowed in Germany?

Is it forbidden? Where in my house I store my bear trap and whether it is set or not is my business, right?

I only say (again): Geese!

Geese are too disloyal, I would be afraid of them myself. But very good as an alarm, that's true.

For the windows in all accessible areas, i.e. the ground floor and on balconies and garages / carports, I would consider the security class. Resistance Class RC 2N would be the minimum for me, maybe even RC3, although then I would need it everywhere and that can quickly become expensive.

Smoke detectors in every room

Moisture detectors in the bathrooms

Leak detectors at tapping points

Window contacts also for shading/heating/ventilation/alarms/presence/absence detection etc.

You can, but you absolutely don't have to. These statements are not part of the minimum requirements!!!!

What fire protection alarm devices/smoke detectors do you have?

The prescribed ones!

So far we had houses without technical safeguards. Now we are considering installing a possible minimum standard. However, we have no experience with the minimum standard. What do you consider absolutely essential for building a house?

The question is what you are aiming for: protection? technology? comfort?

City neurotic. Bungalow, two or three smoke detectors from Lidl are enough. Otherwise, a system according to regulations, nothing burns there. With the new cooktops, you can no longer forget the stove, they turn off by themselves. Fence with a constantly locked gate and exactly one like this in the whole settlement, who moved here from Hamburg. Just a city neurotic.

Breaking in is not allowed either. With a hit, at least it’s a draw 1:1!

The problem is that usually the operator themselves, family members, or visitors become victims of some measures. The bullet from the revolver under the pillow rarely hits the intruder in the backside; mostly it ends up, due to mishandling or stupidity, hitting those one actually wanted to protect.
