Fire at Jamaica Plain Triple-Decker on Wyman Street Spreads Next Door Before Crews Stop It

Fire crews respond to Wyman Street blaze

Boston firefighters battled a morning fire Wednesday, February 18, 2026, at a triple-decker home on Wyman Street in Jamaica Plain, with flames and smoke visible as crews arrived. Fire officials said the fire extended to a neighboring building, adding complexity to operations as firefighters worked to limit damage and prevent further spread.

By late morning, fire officials reported the blaze had been knocked down and occupants were safely evacuated. No injuries were reported in initial updates.

What’s confirmed so far

• The fire occurred at a triple-decker residential building on Wyman Street in Jamaica Plain.
• Fire officials said flames spread to the building next door.
• Heavy smoke was reported at the scene during the response.
• The fire was knocked down and residents were evacuated safely.

Why triple-decker fires can escalate quickly

Triple-deckers are a common housing type across Boston neighborhoods, including Jamaica Plain. In many such structures, fire can move rapidly between units and into shared spaces—such as porches, stairwells, and wall cavities—particularly when flames reach exterior wood components or upper floors. In this case, the reported extension to a neighboring building underscores how closely spaced residential properties can turn a single-address fire into a multi-structure incident.

Fire officials said the blaze spread from the original building to the structure next door, with heavy smoke pouring out during the response.

Investigation and next steps

As with most structure fires, the cause and origin are typically determined after a scene examination by investigators once conditions are safe and overhaul operations are complete. Officials had not publicly identified the cause, the precise point of origin, or the extent of damage to either building in initial reports.

City responders routinely coordinate at fires involving multiple residences, including efforts to confirm all occupants are accounted for, assess immediate habitability, and address hazards such as compromised electrical service, structural damage, and smoke infiltration. Additional updates are expected as officials complete on-scene assessments and investigators evaluate how the fire started and how it spread.
