Construction at KC Jazz restaurant could take anywhere from six to nine months and should start soon, according to developer Casey Granieri, who’s waiting for construction bids.

The former Kelly’s Pub building at Seminary Avenue and Irving Street received Planning Board approval (.pdf) last July. The renovated structure will have a capacity of about 100 people and feature a 1,400-square-foot patio and distinctive 37-foot tower. The second floor will include two two-bedroom apartments.
