A 1905 greystone near the Southport Brown Line station is slated to make way for a new three-unit residential building after Chicago issued a construction permit.
The century-old two-unit building at 3423 N. Janssen Avenue is set to be replaced by a three-story, three-unit residence with a basement. City records show the new-construction permit was issued November 5, 2026, following an application filed May 13.
According to real estate records reported by Chicago YIMBY, 3423 N Janssen LLC, associated with Park Ridge-based Buckley Builders, purchased the property in February for $1.24 million. A demolition permit for the 1905 building and detached garage was issued October 28, listing DemoX as the contractor and a reported cost of $14,000. Whether demolition work has started has not been confirmed.
The replacement building, designed by Michael Cox & Associates, will include a private rooftop deck with pergola, front decks on the second and third floors, and a covered rear deck on the first floor. Plans also call for a detached three-car garage topped by another roof deck. Buckley Builders is listed as general contractor.
The property is less than a block from the Southport Brown Line station. The project continues a familiar pattern in the Southport Corridor, where older two-flats and greystones are being replaced with larger residential buildings. It has not been confirmed whether the three new homes will be sold as condominiums or rented, and a construction completion date has not been announced.
