Sioux City's Housing Maintenance Code requires a working smoke detector on every floor level of a dwelling unit, including basements, meeting NFPA 72 standards, with a hearing-impaired alarm if needed.

Each dwelling unit must have at least one battery-operated or hard-wired smoke detector in proper operating condition on each level of the dwelling unit, including basements, but excepting crawl spaces and unfinished attics. Smoke detectors must be installed in accordance with and meet the requirements of the National Fire Protection Association Standard (NFPA) 72 (or its successor standards). If the dwelling unit is occupied by any hearing-impaired person, smoke detectors must have an alarm system, designed for hearing-impaired persons as specified in NFPA 72 (or its successor standards).
