How steep is the access to the carport?

Hello,

our plot has a slight slope (2m over 35m length... but not completely evenly sloping) and we are currently considering how exactly to arrange the different elements (house, storage/pantry room, carport) regarding the height relationships. I would need opinions/experiences about the gradient of the driveway under the carport. We want to place the carport 3m away from the boundary (more is theoretically possible but would interfere with other plans, so it should stay at 3m or less if possible). Now the question: what height difference can be bridged over these 3m without making the driveway too steep? (Carport would be higher than street level)

In the garage regulations (keyword ramps), there are basic rules about how 'angles and slopes in public parking garages' should be designed. Perhaps orient yourself accordingly.

Where can one find such garage regulations? In the state building code or where?

We were faced with the same question. In general, a 15% gradient is considered drivable. However, our architect strongly advised us not to exceed 12%, as 15% can already be quite tight for some cars.

Thank you very much! Then I will try to find a solution where Max would come out at 12%.

Does the development plan allow this?
Usually, at least 5 m distance to the street is required.
