Las Vegas firefighters responded to 3125 Sequoia Avenue, near Washington Avenue and Mojave Drive at 9:34 a.m. Wednesday.
Fire dispatchers received several 9-1-1 calls that smoke was coming from a vacant house on the street.
Smoke was showing when firefighters arrived at the two-story wood frame boarded up house.
Firefighters got inside the house and found a fire on the first floor. The fire was brought under control in a few minutes.
Fire investigators believe the fire started from a warming fire used by squatters that were inside the house.
Neighbors said the house has been vacant for the past several months.
Damage was confined to a small portion of the house. Damage was estimated at $20,000.
Firefighters from Clark County and North Las Vegas also assisted at the fire.
