George Barr has been charged with murder in the shooting death of 20-year-old Salis Hanrahan, police announced on Friday.
The shooting happened in the 400 block of Ripka Street on Wednesday.
Police said the contractors told officers they were out back putting siding on the house at around 2:15 p.m. before at least one shot was fired inside the home.
That's when Hanrahan collapsed on the sidewalk after he walked outside, suffering from a gunshot wound to the chest. He was pronounced dead a short time later.
The homeowner, now identified as Barr, was taken into custody and police say a firearm was recovered from the scene.
Police has not released details about what led to the shooting.
Barr was arraigned Thursday night and was denied bail.
The investigation is ongoing.
