Rescue teams pulled out around 60 people from a collapsed five-story apartment building in the Mahad's town in Raigad district, 160 kilometers (99 miles) south of Mumbai, the district administration said on Tuesday.
The building, comprising 47 apartments, collapsed on Monday evening, Maharashtra state police said.
India's National Disaster Response Force (NDRF) sent rescue crews and canine teams to the site.
At least two one have been confirmed dead, and 25 are still trapped under the rubble, district officials said.
"Initially, the top three floors of the building collapsed when some people came out," said Nidhi Choudhari, the District Collector. There were fewer people in the building since Monday was a working day, she said.
