Dozens of firefighters and police cordoned off the area as a precaution.
The Red Cross says it has opened a reception center to care for the displaced, who are residents of buildings near the one that collapsed.
Red Cross spokeswoman Michelle Lemieux says it is uncertain when they will be able to return. She says it depends on what happens after the damaged building is demolished.
A shelter has been opened at 60 Temple Street. Volunteers and staff will be providing families and individuals with their immediate needs, including food and a place to sleep.
