A couple of hours earlier, at 11.25pm, crews from Dewsbury and Mirfield fire stations were called to an electric scooter on fire at Ledgard Wharf in Mirfield.
An ambulance was called to help a woman suffering from the effects of smoke.
At 5.33am today (Sunday), teams from Dewsbury, Mirfield and Ossett fire stations were deployed to a building on fire at Ravenshouse Road, Dewsbury Moor.
