The first unit arrived at 3:20 a.m. and reported smoke and flames coming from the small, single-story home, HFD said in a summary of incident.

Firefighters searched the home and confirmed that no occupants were inside the structure.

The blaze was brought under control at 3:36 a.m. and extinguished at 4:05 a.m., HFD said.
