A 24-unit apartment building on South Federal Circle in Littleton was evacuated Monday after a fire was reported.
City spokeswoman Kelli Narde said the structure itself was not believed to be in danger but that flames had been detected in the walls and roof.
"It's a stubborn fire," she said. "It's under control. But it's in the walls and roof."
Littleton City Council member Randy Stein has resigned after less than a year and a half on the council.
In a weekend interview, Stein tied his resignation to results of the March 3 special election, when Littleton voters put restrictions on financing methods the city can use in urban renewal efforts.
Stein, a real estate developer and mediator whose district included downtown, said a threatened recall effort by the Historic Downtown Littleton Merchants was not a factor in his decision to step down.
