Sorry if this is too location-specific, but I have a question I'd like to get other designer/engineer input on. The Chicago Building Code (Section 15-16-600) specifically has their own density/area requirements, with a minimum of 0.10 gpm over 1,500 sqft for NFPA 13 applications.
Does this mean that they do not accept residential sprinklers (most demanding 4 adjacent residential sprinklers)? Do they also not accept the area reductions for quick-response sprinklers?
Based on the requirement in the code they certainly have the ability/right to override NFPA 13, I just haven't seen any other jurisdiction overrule the allowances in NFPA 13 and was curious if this holds up for other installers in the area.
