How many meters does it take for the property to draw a parking line at the door?

This question is very simple, and it is very simple for ordinary community businesses to ask this question. Under normal circumstances, parking spaces can only be marked at least 10 to 8 meters in front of the shops in the community. If there is no width in front of the residential shops, parking spaces cannot be issued. No matter in front of the shops in each urban planning community, there are enough parking spaces. Plan the width and length of parking spaces.
