Seattle firefighters battled a large fire on Monday afternoon along a popular strip of businesses in the Ballard neighborhood.

The fire damaged at least five businesses on Market Street and 24th Avenue Northwest, according to the Seattle Fire Department.

It was major in terms of fire size, according to Seattle Fire spokesperson Kristin Tinsley. Two-thirds of on-duty Seattle firefighters were on site battling the blaze.

"Three alarm fires are not very common, they happen every couple of years according to Seattle's history," she said.

This was the largest since the Queen Anne warehouse fire in November of 2018, which destroyed the building.

An employee of Supercuts called to report smoke around noon, said Tinsley.

She said everyone evacuated safely from the buildings that were impacted.

"There are some apartment buildings that are close by to the strip mall, so we're asking members of the public to close their windows and doors to avoid exposure to smoke," Tinsley said.

One firefighter was hurt and sent to Harborview for treatment on minor injuries. Tinsley said the firefighter was transported there as a precaution.

Tinsley said the cause wasn't yet known and that officials were interviewing those who first reported seeing smoke.

The fire started on a block that includes Supercuts, Kitchen and Things, La Isla, and other restaurants.
