The fire at an Ogdensburg auto garage has been ruled accidental.
Officials said the blaze at C&D Auto started as the owner was working on a gas tank on a vehicle.
C&D, also known to many as Peabody's Garage, caught fire Tuesday at around 10 a.m.
The building was destroyed and was not insured.
Owner David Peabody and a couple of workers were in the garage when the fire broke out. No one was injured.
