City Council voted 7-0 to tear the house down, seeing no viable use for it in the future.
The house, which was purchased by the city during an acquisition of land for the downtown project, is located in a spot where power lines need to be installed.
Mike Hall, of Jones Lang LaSalle, a consultant company working on the project, said a decision needed to be made quickly to avoid paying additional costs to Georgia Power.
Council members were in agreement that they did not want to see the house torn down, but said it couldn’t be used for anything productive and would cost too much to keep.
“If it’s the best thing for the property and the city to get it out of the way long term, it hurts to do, but that’s the right thing,” said Councilman Chris Owens.
A report by Jones Lang LaSalle, with input from city staff, found that the house could only serve the purpose of being a house without “significant alterations.”
Bringing the building up to current commercial-use codes, such as making it accessible to those with disabilities, could cost upwards of $100,000, according to Hall.
Rerouting power lines underground could cost about $250,000.
During public comments, Alpharetta Design Review Board member Richard Debban asked if the house could be sold and moved to another lot.
But Mayor David Belle Isle said time would not allow for that kind of undertaking.
The cost to demolish the house will be about $25,000 and the site can be used to build a new commercial building in the future.
