State building code
Compliance with the current state building codes as well as fire protection DIN 4102, which was already revised in 1993, were revised again in 2002. However, the aforementioned points are not always a requirement in practice. Especially when building in existing buildings, fire protection is sorted into two subitems: necessary measures to avert specific dangers and grandfathering. This means that if the existing building is "safe" in terms of fire protection and has been properly constructed, the old, approved regulations are sufficient and you are grandfathered.

Retrofitting
If this is not the case, the necessary fire protection must be retrofitted. Furthermore, the system of requirements has changed in recent years. Since the building regulations were changed in 1993, the rating is based on “metres above the ground of the highest lounge”. Previously, a distinction was made between four building types with counting of the floors. As a result, the public buildings and tall townhouses now often have higher requirements than before.

Free-standing buildings with up to two full storeys and up to two usable units used to have no requirements above the basement - like building class 1. Today, however, the basement must have fire resistance class F 30.

Building types

Lined up buildings of the same size were given fire resistance class F 30 throughout, similar to building class 2.

With three to five full storeys, walls with fire resistance class F 90 and ceilings with fire resistance class F 30 were sufficient. Most of the houses with wooden ceilings were built in this way, some of which were also built with considerable heights. From today's perspective, these buildings are rather problematic to look at.

As early as around 1900, fire resistance class F 90 was required over five full storeys. These buildings are less of a problem today, because the target direction has not changed, although the requirements may be different in terms of technical details.
