JACKSONVILLE, Fla. -- A San Jose area home worth more than $2.5 million went up in flames Thursday night, according to Tom Francis, spokesperson for JFRD.

The fire broke out in the laundry room/butler pantry and had already caused an estimated $200,000 worth of damage at the time of Francis's statement. But Francis said that figure only represents the structure; the value of items damaged remains unknown.

Due to the amount of damage done to the home near San Jose and Baymeadows Road, Francis said the state fire marshal's office will look into the actual cause of the fire.

When fire crews first arrived at the scene they encountered flames as soon as they got inside the entryway, and the fire was eventually elevated to a two-alarm fire. It's rare, Francis said, for a residential fire to become a two-alarm fire.

After the second alarm arrived, there were over 40 firefighters on the scene, according to Francis, and they had the fire in the more-than-10,000-square-foot home under control in about 45 minutes.

The home's residents were able to get out of the home safely.
