Within about 15 minutes the fire had grown to a three-alarm fire, the release states.
Mutual aid from Chatham, Dennis, Brewster, Yarmouth and Orleans responded to the scene, while other units from across the mid- and outer-Cape covered the stations of responding companies.
Early into the fire the roof began to collapse, but no injuries were reported in the blaze at the vacant motel.
The building was a total loss, the release states.
Anyone with information on the fire should contact the Harwich Fire Department at 508-430-7541 or the State Fire Marshal's Arson Hotline at 1-800-682-9229.
