Monroe County investigators said they narrowed the source of the pre-dawn fire down to a meeting room in the small upstate community's fire hall; however the cause was not determined.
The Rochester Democrat and Chronicle credited volunteer Rich McQuilkin with saving seven vehicles valued at $3 million from the burning station.
The building was declared a total loss and ordered torn down. The fire also claimed a rescue boat and all of the department's 40 sets of turnout gear, the newspaper said.
Village officials have positioned the surviving fire trucks at various locations to ensure Spencerport has adequate fire protection.
