BAYSIDE, Wis. (CBS 58) -- Dozens of people are out of their homes after a massive apartment building fire in Bayside. 

At least 15 people had to be rescued from the White Oaks apartment complex over the weekend. 

The Red Cross says it's been flooded with donations for those who lost everything in the fire. They set up a shelter for the victims at St. Eugene's Church. 

Over the weekend, several people stopped by to donate items like clothes and toiletries. Now, the Red Cross says it's in need of furniture and monetary donations. 

"The fire department kicked our door in and they were in full mask, yelling," said one woman who was inside the building when the flames broke out early Saturday morning. "The main area of our hall, it was just like filled with water and then when we were outside and looked up all you saw was just the entire roof just covered in flames."

The woman said she was in the process of moving so her clothes and kitchen items were already out of the building. She says she lost her furniture and school supplies and her cat is now missing. 

Authorities are still working to learn the exact cause of the fire but say it likely started on a first or second-floor balcony.

BAYSIDE, Wis. (CBS 58) -- Firefighters with the North Shore Fire Department held a press conference Saturday on a large fire at the White Oaks apartment complex in Bayside.

Officials said they received multiple 911 calls around 12:15 a.m. early Saturday morning. The apartment building has 62 units with three stories and is one of several buildings in the complex.

When firefighters arrived there were multiple people on balconies who had to be rescued. Some tenants were rescued by ladders off their balconies. Others were rescued by going through the actual apartments with firefighters. Officials say between 15-20 people were rescued.

Two tenants were taken to the hospital with minor injuries. A firefighter was also taken to the hospital with injuries and later released.

Some residents have been able to access their apartments to retrieve necessary items but officials say only half of the building is secure. Authorities say they don't have a full count of all the people in the building but say everyone is accounted for. 

The State Fire Marshal has made a preliminary determination that the fire is not suspicious. An exact cause has not been determined but it could be electrical in nature. Damage to the apartment building is significant and could be a total loss.

A shelter has been set up by the American Red Cross at St. Eugene's Church in Fox Point. According to officials with the Red Cross, local restaurants have been donating food and the community has been bringing in clothing and other essential items.
