Several jurisdictions have amendments that I think are very good at addressing this. Here is one example:
Definition: Car Stacker – A manual, or automatic, rack storage system designed to park cars vertically and/or horizontally such that the vehicles are in close proximity to one another and pose an additional hazard due to fire spread. Design Density : Parking areas inside buildings or under attached canopies equipped with car stackers shall be protected by an automatic fire sprinkler system designed to a density of Extra Hazard Group 2. Standard coverage sidewall sprinklers, listed for Ordinary Hazard shall be provided under each parking level, including the bottom level if the car stacker uses a basement or pit area. The maximum coverage of a sidewall sprinkler is 80 sq. ft. and the use of extended coverage sidewall heads for protection is prohibited. Design Area:The area of application shall be 2,500 sq. ft.. Exception: The area of application may be reduced, but never less than 1,500 sq. ft. if: a. One-hour rated walls are provided between the stacker parking area and other standards parking stalls or storage areas; b. The car stacker system is divided into maximum 1,500 sq. ft. floor areas by one-hour fire barriers NOTE: For hydraulic calculations, flow from all fire sprinklers, upright, pendant and sidewall sprinkler heads, at all levels, located in the area of application, shall be included in the hydraulic calculations.
