Codes and Standards Referenced by the Illinois Fire Sprinkler Contractor Licensing Act
Domain 4 - Codes and Standards Referenced by the Illinois Fire Sprinkler Contractor Licensing Act
This domain tests whether you know which standard governs which decision. The Act and OSFM rules point to National Fire Protection Association standards rather than a single generic “sprinkler code.”
Core rules
- NFPA 13: commercial, industrial, and most multi-family sprinkler design and installation.
- NFPA 13R: limited residential occupancies, generally up to four stories; do not use it for high-rise or mixed occupancies that exceed its scope.
- NFPA 13D: one- and two-family dwellings and manufactured homes.
- NFPA 14: standpipe and hose systems.
- NFPA 20: fire pumps.
- NFPA 24: private fire service mains and appurtenances.
- NFPA 25: inspection, testing, and maintenance of water-based systems.
- The edition adopted by OSFM controls; local amendments may be stricter. Verify the project’s adopted edition before citing a clause.
Worked example
A four-story residential building with an attached commercial tenant asks whether NFPA 13R applies. The residential portion may fit 13R only within its scope; the commercial tenant and any height or area exceedance push the design to NFPA 13. The standpipe, if required, follows NFPA 14, and the fire pump, if present, follows NFPA 20.
Traps
Citing NFPA 25 for design; using 13D for a multi-family building; assuming the newest edition is automatically adopted; and ignoring that NFPA 13R is not a substitute for NFPA 13 in mixed-use or high-rise conditions.
