The minimum clear height of a parking tier in an open parking garage must be how many feet?

The minimum clear height of a parking tier in an open parking garage is generally set at 7 feet to accommodate standard vehicles and ensure safe access. This height is sufficient for most passenger cars and light trucks, allowing occupants to enter and exit the vehicle comfortably. Additionally, building codes often specify this minimum to maintain adequate space for vehicular movement, as well as for any potential clearance issues associated with the garage structure itself.

Higher clearances may be required in different contexts, such as for larger vehicles or in specialized parking situations, which is why options indicating higher clearances are available. However, for standard open parking garages catering mainly to regular passenger vehicles, 7 feet remains the baseline standard for clear height.
