UPDATE: Firefighters were called to tackle a blaze in Perth's southern suburbs this evening.
The fire burnt through a building in Myaree.
A Department of Fire and Emergency Services spokesman told The West Australian that 10-12 fire trucks were at the scene.
The fire started about 6.15pm and was under control before 8pm.
The cause of the fire is not yet known.
DFES said it was a structure fire at a building on Malland Street in Myaree.
The premises' business is believed to be AAA Production Services, which offers event management services specialising in audio-visual hire and sales and event production.
Parts of Myaree, Alfred Cove and the eastern part of Melville - north-west of Malland Street - were impacted by smoke from the fire.
About 25 Fire and Rescue Service firefighters are at the scene mopping up after extinguishing the flames, although some "hotspots" remain, the DFES spokesman said.
"People in the area should remain inside, out of the smoke or fumes, with doors and windows closed as a precautionary measure," DFES warned at the height of the fire.
People were urged to stay away from the area and those with medical concerns should contact their GP or Health Direct on 1800 022 222.
