ROCHESTER, N.Y. (WROC) — The Rochester Fire Department (RFD) reported to a third alarm structure fire early Wednesday morning on East Avenue.

The RFD says they responded to a possible building fire at 5:40 a.m. Wednesday morning at 318 East Avenue — an over 16,000 square feet building in the back of Veneto Wood Fire Pizza.

According to the RFD, the first company arrived at the location within three minutes and reported heavy smoke coming from a one and a half story block building. They add that after crews were able to force themselves into the building, the building had multiple rooms on fire.

The fire was contained in a tool shed inside of the building, according to the RFD, which was knocked down quickly. They add that the fire became a third alarm due to the size of the building and all of the different business attached to it.

The RFD says the fire damage has been isolated to the one and a half story block building with heavy fire damage in the void space between the ceiling and roof deck with smoke damage to the other parts of the building.

No injuries were reported as a result of the fire. The RFD says one person was home at the time of the fire and was able to escape on their own. They add that a cat had to be rescued from the building.

The RPD says the cause of the fire remains under investigation.
