    The area of the pit would not be considered for parking. The pit would be concrete. Zurn oil pit, in the pit for residual oil clean-up. Exhaust vents near the floor with an exhaust fan piped to the outside. I have this exact scenario, residential, not commercial. My second bay is used for parking.
