LAS VEGAS (KTNV) – The Clark County Fire Department is investigating a fire that saw three homes under construction on Friday night.

According to the agency, crews responded to 8754 Whistling Sands Avenue near Spring Mountain Road and Durango Drive just before 7:30 p.m. after several 9-1-1 callers set a new construction site on fire.

A high-level F3H fire response was triggered, including four engines, a ladder cart, a rescue operation, two battalion chiefs, and an air resources unit.

Arriving crews found a fully involved house under construction and the two neighboring houses under construction had started to burn.

Firefighters first aggressively attacked the two partially affected houses and then wiped out the completely affected house.

The fire was declared down shortly before 8 p.m.

The fire was contained in the affected houses and did not extend into the adjacent construction.

The cause of the fire is still being investigated.

No fire injuries are reported. The estimated damage is $ 400,000.
