Hi,
In my building application, the garage is planned with a pitched roof. It is an 8x6m garage (finished foundation) plus a 6x6m carport in front. We have now realized that the 6m (20 feet) wide carport is a bit too narrow. So, we want to make the roof wider to 7m (23 feet). It would only look okay if we make a flat roof instead, where the garage part would have a 1m (3 feet) roof overhang on the side.
In the building application, the garage is naturally shown with the pitched roof. Otherwise, there is no specific information or anything. Is it possible to just switch to a flat roof, or will that definitely cause problems?
As far as I remember, I don’t need a building permit / planning permission for a garage up to 50m² (540 sq ft), right? 6x8 = 48m² (516 sq ft) - the rest is just a carport...
The problem is: there has been a change at the building authority. The new building inspector is convinced that the old one should never have approved our project. So if we come with changes now, he will definitely reject them. If we just start building, probably nobody will notice. It is approved anyway – just with a different roof...
What would you do?

You are allowed to build up to 50 sqm (538 sq ft) in SA including a garage or carport!
Do I understand correctly that in addition to the 48 sqm (516 sq ft) garage, there will be an overhang of X meters on both sides? What would that look like?
Where would you be then? Over 50 sqm (538 sq ft)...

What isn’t clear to me is: can you use the 50 sqm (538 sq ft) allowance once for the garage and again for the carport? I don’t think so... it probably applies to the total area, right? That’s why you submitted a building permit / planning permission application, I assume?!
But someone else here surely knows better.

Personally, I wouldn’t have any issues with the roof shape :cool to build it), as long as the flat roof does not violate any public law regulations.

Am I understanding correctly that on top of the 48 sqm (516 sq ft) garage, you get some additional overhang on both sides? How does that look?
Wouldn’t that put you over 50 sqm (538 sq ft) ...?

*Giggles*, uh no. The carport is attached to the front, extending forward. It’s basically a 14 m (46 ft) long roof and 7 m (23 ft) wide.

Well, I’m not sure either. I thought the building permit always covers the total built-up area, right? That would only be 48 sqm (516 sq ft). Since it’s such a long roof without any supporting walls underneath, I probably don’t need approval for it, or do I?

There are no specific regulations. Just the building permit. I think the garage was only included in the building permit application for the sake of completeness regarding the elevations. But once it’s approved, it’s approved.

Counterexample: If I had a garage where I wanted to add a new roof with a 3m (10 feet) roof overhang, I wouldn’t need a building permit / planning permission as long as I maintain all the required setbacks and do not construct anything that violates local building regulations, right?

So, roof overhangs are also included from a certain depth when calculating for a single-family house. This will also apply to carports and garages. It’s mainly about the sealed surface area. Haha, our carport is built on four 40cm x 40cm (16 inches x 16 inches) post foundations, so of course the roof, including the overhangs, counts! Not the four foundations themselves, nor the spacing between the posts, but the area covered by the roof.

With your 14 x 7 dimensions, it’s unclear whether this refers to the planning or your new project. For a 6 x 8 garage plus carport, I’m calculating about half a meter (20 inches) of overhang on the left and right sides of the garage?!

Try drawing it out: what is included in the permit and what you want to build now. I assume that anything larger than 50m² (540 sq ft) requires an application.

Dimensions like 14 x 7 (or even 6) are already significant. I can’t imagine that a garage and carport of this size (50m²) would be exempt from approval. Are they planned on the property boundary?

But this is all just an amateur opinion based on regulations from Lower Saxony compared to Saxony!

Regulations might include, for example, a maximum size of 50m², likely a maximum of 9 meters (30 feet) for boundary construction, and a height limit of 3 meters (10 feet). These are just examples of what regulations might be. You can usually find this information online. You will also have public law regulations in South Australia/Saxony.

Okay,
we asked our builder. The rule seems to be as follows:
For a building with a roof overhang greater than 1.50m (5 feet), the entire roof overhang is included in the enclosed space. So, we are clearly above 50m² (540 sq ft).
Therefore, a building permit / planning permission is required.
