AUSTIN (KXAN) — An electrical fire at a North Austin apartment complex forced a building evacuation for a short time early Tuesday morning. The fire broke out just after 4 a.m. at the Atrium Tech Ridge Apartments at 305 East Yager Lane. Firefighters found the origin in the walls of a third floor apartment. Investigators estimate the fire caused $1,500 in structural damage. One person must find another place to stay because of power being shut off to the affected apartment.
