Healdsburg firefighters were battling a fire at a warehouse Tuesday night between Highway 101 and Healdsburg Avenue.

Initial reports of the fire, at Aaction Rents in the 1400 block of Grove Street, said flames were seen in the attic of the building, according to a fire dispatch supervisor.

Arriving firefighters quickly called for help from other agencies, including from Windsor, Geyserville and Santa Rosa. Details about the fire were sketchy late Tuesday.

Aaction Rents rents various kinds of tools and other equipment, including tractors. The adjacent Encore Events Rentals handles party rental equipment such as tables, linens and tents.

The area is an industrial zone northwest of downtown Healdsburg.
