Hello everyone,
I have been in the planning phase for some time now and have an issue regarding the slope of my driveway.
I want to position my house 10 meters (33 feet) away from the road on the property. A rough initial measurement showed that the height difference over these 10 meters (33 feet) is about 2.5 meters (8 feet). Therefore, we plan to integrate our garage directly into the basement.
I have calculated that my driveway, which leads to the side entrance of the house, has a slope of about 28%.
2.8m (9.2 feet) ÷ 10m (33 feet) × 100 = 28%
I found a regulation online for garages stating that the maximum slope should not exceed 15%.
So my questions are:
- Is this maximum slope of 15% correct?
- If not, what would you consider comfortable and realistic?
Any information about the slope of your own driveways would be very helpful as well. Pictures are welcome.
Thank you very much for your help.

This means there is no slope on the property, and the garage is likely located in the basement simply due to space constraints. Unfortunately, I can’t tell you how steep the incline is. He drives from the street into his house/garage/basement with a 90-degree turn.
If I manage, I’ll try to take a photo of it.

In Landsberg/Lech, the old mountain road has an 18% gradient and for this reason, during the era of horse-drawn carriages, it was the only road in Germany with left-hand traffic. This was done to give the drivers a slight chance of survival if the brakes on the carriage failed, as they could escape by making a dangerous jump to the roadside.
"Due to the steep 18% slope, accidents with horse-drawn carriages frequently occurred on the salt road in the past. To avoid injuries, drivers had to walk on the left side of the carriage. It was also forbidden under penalty to lock house doors so that pedestrians could seek refuge inside if out-of-control teams approached. Additionally, stone bollards were placed on the downhill left side, against which the drivers could steer their teams in case of emergency. These 'braking blocks' still exist today." (Wikipedia)
Just to get a sense of the steepness...
I consider a 28° slope a no-go!
