Should your local government prioritize granting landmark status to historic buildings to prevent their demolition?
On September 21, 2026, preservation groups recommended that the city designate the O'Leary mansion at 726 W. Garfield Blvd. as an official landmark. The move follows reports that the 125-year-old estate is currently entering demolition court.
Why it matters
The mansion is valued for its Renaissance Revival architecture designed by Zachary Taylor Davis and its historical ties to the prominent O'Leary family. Securing landmark status could prevent the loss of this unique architectural site in Chicago.
The home features 33 rooms and is over 125 years old, having been built in 1901. It must meet the city's 7 specific criteria to receive formal landmark protection.
The players
Zachary Taylor Davis
The architect known for designing the O'Leary mansion in a Renaissance Revival style.
Commission of Chicago Landmarks
The municipal body responsible for evaluating and granting landmark status to historic city properties.
James O'Leary
A notable figure in local history who resided in the 726 W. Garfield Blvd. mansion until his death.
The details
The Commission of Chicago Landmarks reviews suggested properties to determine if they meet mandatory ordinance requirements for protection. Preservationists argue that the site qualifies due to the significance of the architect, the architectural style, and the history of the O'Leary family. The property has faced recent uncertainty after being listed for sale in May 2024 and subsequently removed from the market in August 2024.

The Home Front

Homeowners in historic districts should monitor official city notices regarding property zoning and demolition filings. If your property has historical significance, consult with the Commission of Chicago Landmarks to understand the eligibility criteria for protection status.
The takeaway
Preservationists are actively seeking to save the historic O'Leary mansion through formal landmark channels. Concerned residents can track the property's status through public meetings hosted by the Commission of Chicago Landmarks.
