The responsibility for Scott Towers’ upkeep rests with the Greenville HA, who also owns the land, rather than with HUD. The director essentially admitted not properly maintaining the building, which would have made renovation more practical. The interior on the news looked nicer than expected, certainly not demolition-worthy. Whatever problems there are were preventable and/or repairable, with routine maintenance and planned phased-in renovations.
It’s difficult to imagine the complete cost for total demolition, removal, disposal, tenant relocation, new design and construction would be less than upgrading an existing building; especially if it had been done over the last several years.
Here is a Greensboro HA high rise for the elderly, built around the same period as Scott Towers, that has been renovated. Its facade is in better shape than Scott’s, but facades can be improved.
