PHOTO: It took firefighters 15 minutes to put out a house fire in Jacksonville’s Avondale neighborhood on Monday morning. Crews with the Jacksonville Fire and Rescue Department told Action News Jax they are investigating it as a result of arson. JFRD shared a picture on Twitter that shows what firefighters faced when they first arrived to the house in the 3800 block of Boone Park Avenue around 6:15 a.m. No one was in the house at the time of the fire and a state fire marshal is investigating. The fire appears to have started in the stairwell of the home, according to JFRD. The house is a new home that was under construction. JFRD reported the home is not a total loss. Police have the area roped off.
