Summary

Wilmington's building rehabilitation code requires day nurseries and residential child care facilities to enclose boiler and furnace rooms in one-hour fire-rated construction, and limits the automatic-sprinkler exemption to small day care centers keeping children under 2½ on the ground floor.

Boiler/furnace equipment rooms shall be enclosed by one-hour fire-rated wall and ceiling assemblies for day nurseries, children's shelter facilities, residential child care facilities and similar facilities with children below the age of 2½ years.

Full Breakdown

Under the city's Existing Building Rehabilitation Code (Wilmington City Code, Chapter 4, Subchapter 6), any boiler or furnace equipment room serving a day nursery, children's shelter, or residential child care facility with children under 2½ must be enclosed in one-hour fire-rated walls and ceiling assembly. The rule applies within the Institutional (I-2) use-group standards triggered whenever such a building is repaired, renovated, altered, or reconstructed. A related exception waives automatic fire suppression only for day care centers with 100 or fewer occupants where under-2½ children stay on the first floor with a direct exterior exit from every child care room. License and Inspections enforces compliance through plan review and inspection.

Violations & Fines

Violating the rehabilitation code's fire-rated construction rules risks a $250-$1,000 fine (up to $5,000 for a corporation) or six months' imprisonment, with escalating fines for repeat convictions.
