The store I rented is engaged in car service. Recently, the property project department informed us to enclose the open space in front of the door as a parking lot. Is it reasonable for them to do so?

Explain that the pavement in front of the store is a residential area, not a social area. If the community owners demand this property, they have the right. If they don't ask for property, they can also develop this charging resource. After all, it is a management unit. It depends on how you write your lease contract. I didn't say you were unlucky. Look at the contract and sign it later. In other words, I rent your house, and there is no open space around, so I have the right to dispose of it, understand?
