Fire swept through a Lincoln Park home late Saturday morning.
The house, in the 1800 block of North Fremont Street, was under construction. Firefighters say the fire broke out on the second or third floor. Water pressure problems prompted them to elevate the fire to a two-alarm, which brings in more crews.
Workers were inside the building when the blaze started, but everyone was able to get out safely and no one was injured. The buildings on either side of it were also undamaged.
Firefighters are still investigating the cause.
