Direct answer
The short answer for Boston, MA
Boston's core population of about 654,000 lives in Beacon Hill brick, South End bowfronts, triple-deckers in Dorchester and Jamaica Plain, and Seaport towers. Steam heat and air rising up stairwells, called stack effect, trap the smell of a late discovery. Near the universities, units that sit empty between terms can mean a longer gap. This guide covers release by the Massachusetts Office of the Chief Medical Examiner, stoop versus freight paths, closing off returns, landlord files, and keeping things discreet on the sidewalk. No Boston office, named crew, or arrival window is claimed here.

Local planning context
Each neighborhood's buildings fail in their own way. Bowfronts on Beacon Hill and in the South End share party walls and load out over the stoop. Triple-deckers in Dorchester and Jamaica Plain force sealed bags down narrow stairs past other households. Towers in the Seaport and downtown need freight bookings and lobby protection. Units near the universities may sit empty between terms until a landlord walks through. Old pine floors in triple-deckers soak up fluid, and in winter the storm windows stay shut. Name the type, bowfront, triple-decker, or tower, before anyone plans a wipe-down.
In the cold months, stack effect pulls air up the stairwells. A parlor door propped open can fill the landings with odor chemicals from wet mattresses. In July, a window unit just blows the smell around the room. Soft goods left in basement storage cages become a second source after first responders leave. Flies at the windows of a unit left empty between student terms often mean a longer gap. Floating vinyl put in during remodels hides a soak that spread sideways. Check the garden-level unit below too.
The Massachusetts Office of the Chief Medical Examiner looks into qualifying deaths across the state. That is unlike New York City's city-run office or the county offices in New York's suburbs. Local police holds may still control entry. Landlords, condo associations, and executors should agree in writing on what to save. Sidewalk stoops call for opaque carts. Keep photo lists for insurers and probate. Treat store-bought fresheners as extras, only after the soaked materials are gone.
