Dual demolition permits have been issued for two adjacent multi-unit buildings located at 2454-56 W Ainslie Street in Lincoln Square. Both permits list Eamon Gibbons as the owner, whose plans for the properties have not yet been published. However, both parcels are zoned for RS-3 Residential Single-Unit District, which allows for detached single family homes and two-flats. This designation also allows for a floor area ratio of 0.9, by which any new building’s square footage may not exceed 90 percent that of the lot itself.
