The cause of a house fire in Montrose early Wednesday morning remains under investigation by Kootenay Boundary Regional Fire Rescue (KBRFR).
Sixteen firefighters from Trail, Montrose and Fruitvale arrived at the scene, located on 9th Ave., just before 4:30 a.m.
Flames were contained to the basement with smoke damage to the upper floor, said KBRFR Captain Greg Ferraby.
He noted that the incident was under control within 30 minutes.
The home's two occupants were inside when the fire started, and as a precautionary measure, transported by BC Ambulance to the regional hospital to be assessed for smoke inhalation.
No injuries were reported by the rescue crew.
Investigators from the fire department and insurers were still at the site in the late afternoon, though no cause had been determined by press time.
This is the first call out for a structure fire in KBRFR this year.
