ᐅ Garage – Building Permit – Confusion

Hello,

we have submitted our building application for our single-family house with a (separate) double garage (5.85m x 8.94m (19.2 ft x 29.3 ft)).

The double garage is made with steel panel construction, so it is a prefabricated steel garage.
State: Brandenburg.

The garage is planned to be built with one side (8.94m (29.3 ft)) directly on the property boundary.

The problem now is that, according to the Brandenburg garage regulations, this wall (boundary wall) must be a fire wall!!
This is not the case with our prefabricated steel garage.
At least, this is what our building regulations officer is currently pointing out...

The garage company has already installed several of these garages, also nearby, and they are hearing about this issue for the first time.

Other customers never included their garage in their building application process, so they never had problems here.

Now my question is, can this be true?
What should I do?
Upgrade the one wall into a fire wall – which apparently requires a 24cm (9.4 in) thick wall?
Remove the garage from the building application and then simply install it afterwards?
As far as I know, the garage is basically permit-exempt.

Has anyone experienced similar problems before?

Garage Regulations of the State of Brandenburg

[B]§ 10
Firewalls

(1) Instead of firewalls according to § 26 section 2 nos. 1 to 3 BbgBO, the following are sufficient:

  • for single-story above-ground medium and large garages, fire-resistant partition walls without openings, provided the building is used exclusively as a garage,

§ 10

  • for single-story above-ground medium and large garages, fire-resistant partition walls without openings, if the building is used exclusively as a garage,



Here it says for medium and large garages...
According to the definition, we have a small garage (< 100 m² (1,076 sq ft) usable area).

Therefore, paragraph (2) would apply:

  • for enclosed small garages, including storage rooms with no more than 20 m² (215 sq ft) floor area, at least fire-retardant or non-combustible partition walls without openings.
However, our floor area is 5.85 x 8.94 = 52 m² (561 sq ft).

And the letter from the building authority literally states:

According to § 10 of the Brandenburg Garage and Parking Space Regulation, for enclosed small garages including storage rooms with no more than 20 m² (215 sq ft) floor area, instead of firewalls according to § 26 (2) numbers 1-3 BbgBO at the property boundary, at least fire-retardant or non-combustible partition walls without openings are sufficient.
Therefore, the planned garage with a floor area of more than 20 m² (215 sq ft) built as a steel element structure is not permitted at the property boundary.

How do you fit a garage including a storage room into 20m² (215 sq ft)? A standard garage is already 3 x 6m (10 x 20 ft) = 18m² (194 sq ft).
Logically, the 20m² (215 sq ft) can only refer to the storage room, not the garage including the storage room. In my opinion, the official handling officer cannot read or interpret their own bureaucratic language.

The error might actually lie in the details! Especially since, by definition, a small garage has a usable area of less than 100 m² (1,076 sq ft), and then the regulation states:

  • enclosed small garages including storage rooms with no more than 20 m² (215 sq ft) of floor area

That would really not make any sense!

So, it seems that the 20 m² (215 sq ft) refers only to the storage rooms, and here we have 3 x 6 = 18 m² (194 sq ft) — so everything is fine. Accordingly, a fire-resistant or non-combustible partition wall without openings is sufficient, which our steel prefabricated garage meets.

Right?

In my opinion, yes. But I am just an amateur.

According to the editor’s interpretation, otherwise every standard concrete garage with an extension (3m x 9m (10ft x 30ft)) would also be prohibited as boundary construction.
