Leamington's fire chief suggests residents check their bathroom exhaust fans for signs of dust build-up after a house fire on Wednesday night.
Firefighters arrived at the house on Oak Street East between Plumbrook Drive and Bennie Avenue just before 7:30 p.m.
Fire Chief Don Williamson said flames erupted in the bathroom exhaust fan and moved into the attic.
A tenant in the rental unit saw it start.
Williamson said it may have been an electrical fire, but dust build-up may have contributed to it.
The house is older with multiple additions, so he wasn't sure how many people live there.
Damage is estimated at $250,000.
