Demolition permits were issued this past week for three-story masonry residence and a detached frame garage, located at 2820 N Rockwell Street in the Avondale neighborhood. The owner is listed under 2820 N Rockwell LLC, whose plans have not been revealed. The property’s zoning designation of RT-4 permits two-flats, townhomes, low-density apartment buildings, and single-family homes. RT-4 also permits a floor area ratio of 1.2, in which any new construction may have up to 1.2 times the square footage of the containing lot. It is not clear whether the owner will seek a zoning change.
