Whether the lift has a catch pan below the car or not makes no difference. In these installations you can assume the lift is elevated since some people with one car don’t like to drive up and down the ramps. Or the lift is elevated because there is a car parked below. In the case of the lift being in the upper position regardless of whether or not there is a car on it, it becomes an obstruction to overhead sprinklers. A fire originating in the car below can grow without intervention from sprinklers until it involves the upper car.
There are videos on-line of cars in this scenario where when the fire starts in the lower car, it automatically spreads to the upper car. Overhead sprinklers at that point can be easily overwhelmed. Do a Google search for: BRE Fire and Security Client Report number 256618 It’s some interesting reading regarding car stacker fire protection testing.

If the lift plate on which the car rests has lots of openings ( ~ 50% is the line in the sand for racking), then overhead-only should be good. If the car rests on a solid plate to keep oil off what is underneath... I would find a way and a place to put a sidewall under the plate, if it were my condo/garage/car lift.

The owners have individual garages with an option to have a lift installed so that they can get an additional car in. I am sure you know where this is going … sprinklers under the lift or no? I don’t know of any code references that directly address this situation. What say you?
