ᐅ How steep is the access driveway to the carport?

Hello,

our plot has a slight slope (2m (6.6 ft) over 35m (115 ft) length, but not evenly sloping) and we are currently considering how to arrange the different elements (house, storage/pantry room, carport) in terms of height differences. I would appreciate opinions or experiences regarding the slope of the driveway under the carport. We plan to place the carport 3m (10 ft) from the boundary line (more distance is theoretically possible but would interfere with other plans, so it should stay around 3m or less). Now the question is: what height difference can be managed over these 3m (10 ft) without making the driveway too steep? (The carport would be higher than street level).

The garage regulations (keyword ramps) include basic rules on how angles and slopes in public parking garages should be designed. It might be useful to refer to these guidelines.

Where can you find such garage regulations? In the building code or somewhere else?

We faced the same question. Generally, a 15% slope is considered drivable. However, our architect strongly recommended not exceeding 12%, as 15% can already be challenging for some vehicles.

Thank you very much! I will try to find a solution that would result in a maximum of 12%.

Does the development plan allow this?
Usually, a minimum distance of 5m (16 feet) from the street is required.
