SAN FRANCISCO — Authorities say two women were injured when the third-floor balcony of their San Francisco home collapsed.

The San Francisco Fire Department reports the collapse happened early Saturday at a single-family home in the city's Outer Sunset District.

The women were taken to San Francisco General Hospital. The San Francisco Chronicle reports they were seriously injured, but further details were not available.

Fire Department spokesman Jonathan Baxter says police are investigating, and the city's building inspectors will examine the property.

A 2015 balcony collapse in neighboring Berkeley killed six people and injured seven.

An investigation determined that collapse was caused by dry rot in the balcony's wooden beams.
