Chicago FAQ
Do older Chicago high-rise condos need to retrofit sprinklers?
Pre-1975 commercial high-rises must install full sprinkler systems. Residential high-rises may choose alternative life-safety packages including compartmentation, alarms, and elevator recall under the High-Rise Sprinkler Ordinance.
Are sprinklers required in new single-family homes?
Detached single-family homes are generally exempt, but new townhouses statewide require NFPA 13D sprinklers under Illinois IRC R313. Chicago multi-unit residential almost always requires sprinklers.
Tinley Park FAQ
Are sprinklers required in my new house?
It depends on the municipality. Cook County does not mandate residential sprinklers countywide, but several north and northwest suburbs require NFPA 13D systems in new single-family homes. Check with your local fire protection district.
Do I need sprinklers when remodeling?
Major renovations exceeding 50 percent of the structure value, or changes of occupancy, can trigger full sprinkler retrofit under Chapter 32 and the IFC. Smaller projects usually do not require new systems.
