Section 142-15 sits in Article II of Chapter 142, under the heading “Hot ashes and other dangerous materials,” and most people reading that heading would assume it is about fireplaces. Read the sentence: “Ashes, smoldering coals, or embers, greasy or oily substances and other matter liable to cause spontaneous ignition shall not be deposited or allowed to remain within 10 feet of any combustible materials, except in metal or other noncombustible receptacles. Such receptacles shall be placed on noncombustible stands, unless resting on a noncombustible floor or on the ground outside the building and shall be kept at least two feet away from any combustible wall or partition.”
Four words in the middle of it — “greasy or oily substances” — are what make this a cleaning contractor’s section rather than a landlord’s. Rags from polishing and waxing, cloths from degreasing a kitchen line, pads from a stripping job: that is the textbook description of matter liable to cause spontaneous ignition, and it is produced by the visit rather than found on arrival. The section answers it with distances and a container, not with a warning. Ten feet from combustible materials. A metal or other noncombustible receptacle. A noncombustible stand, unless the thing is already on a noncombustible floor or outside on the ground. Two feet from any combustible wall or partition.
The registration and the annual inspection under section 142-9 belong to the building and its owner. A cleaning contractor holds no registration, pays no fee and neither passes nor fails that inspection. What it controls is narrower: what it leaves behind, and where.
The rest of the chapter sets the rhythm. Section 142-9, amended on 14 October 2025, registers every non-life-hazard business use with the Bureau of Fire Prevention and has it inspected once per year, at $85 under 2,500 square feet of gross area, $160 from 2,501 to 12,000, and $235 above that; multifamily dwellings pay by unit count on a separate schedule, and uses that must register with the State as life-hazard uses register there instead. Section 142-9C sweeps anything unclassified into the business category, and section 142-9E leaves vacant buildings inspected on their previous use at the Fire Official’s discretion. Section 142-17A then removes the option of paying and forgetting: the violation is still to be remedied, and each 10 days it stands is a separate offense.
Nothing here describes what any inspector looks for, how often a violation is written or what is commonly found. The chapter is quoted; an inspector's practice is not, because none was read.
