*The Fire Marshal will need to determine if adequate fire-fighting equipment is available when determining number of stories allowed. Fire Code regulations may require greater setback distances or fewer allowable stories than those given in this chart.
**Setbacks for development in R-MF-16 may vary when adjacent to "Triggering Property" based on § 153.214. "Triggering Properties" include: properties zoned A, RE, R1, R2, R3L, R3, and R4, as well as property occupied by a single-family dwelling unit that is a use permitted by right in the zoning district in which it is located.
