Flames were shooting through the roof of the Parsonage Road building when firefighters arrived around 4:30 p.m. Monday.
Some tenants were able to return to their homes to collect some belongings -- others lost everything, Deputy Fire Chief Andrew Toth Jr. said.
One township firefighter suffered a hand injury and was expected to be treated and released, Toth said.
The Red Cross and township Health Department assisted in relocating everyone evacuated from their apartments, fire officials said.
