Firefighters extinguished a fire at the Mercy North Auburn at Rock Creek complex on Sunday night.

CAL FIRE/Placer County firefighters responded to the multifamily structure on First Street before 9 p.m. According to CAL FIRE, first arriving personnel reported smoke showing from the third floor of the three-story complex.

Placer County Sheriff’s deputies evacuated 10 adjacent apartments on both sides of the fire. CAL FIRE reported the affected unit was fully charged with smoke, with a fire in the back corner and an active fire sprinkler.

“The modern building construction and sprinkler systems held the fire in check for the short time prior to firefighters extinguishing the fire,” CAL FIRE reported on its Facebook on Monday afternoon.

CAL FIRE confirmed the fire was extinguished 10 minutes after dispatch and three apartments sustained major fire and water damage. CAL FIRE also replaced the sprinkler and recharged the system.

There were no injuries due to the fire. The cause remains under investigation.

Mercy North Auburn at Rock Creek is a community of 79 homes for low-income and special-needs families. Located on 3 acres of county-owned property on First Street at the Placer County Government Center, Mercy North Auburn at Rock Creek includes 32 two-bedroom apartments, 25 three-bedroom apartments and 22 one-bedroom apartments.

Residents began moving in Jan. 24, 2022, and a ceremony was held in mid May 2022, which included a ribbon cutting and speeches with several area officials attending.

Doug Shoemaker, president of Mercy Housing California, said that day all 79 homes were occupied by working people and about 20 others who were homeless at one time. They were to pay 30 percent of their income toward rent. A few residents stood outside their new homes watching the ceremony.
