Klicker said the male homeowner used a fire extinguisher through a service door to try to control the fire and suffered a burn to the side of his head.

Klicker said it is believed that aerosol paint cans blew up, causing the loud noises.

The garage was a total loss and a damage estimate was not immediately available. No vehicles were inside but there were lawnmowers and other property that was destroyed.

The house, which remains habitable, sustained broken windows from the heat and a board-up company responded to shore up the structure.
