The measure reverses the city’s 68-year ban on tiny homes but creates a patchwork of regulations that could significantly differ from ward to ward in order to uphold the decades-old tradition known as aldermanic prerogative.

A compromise proposal to allow Chicagoans to build basement, attic and coach house dwellings across the city would still give alderpeople the final say over whether the tiny homes could be built in their wards, officials said.

The rare rejection by the Chicago City Council’s Finance Committee means the proposal will not advance to the full City Council for a final vote. Its sponsor said the measure would give 17 members of the City Council the power to stop Johnson from burdening future generations with massive debt obligations.

If approved by the full City Council, violations of the ordinance could trigger fines of at least $2,000 and no more than $5,000. A final vote on the measure could come at the City Council meeting scheduled for Jan. 15.

The Chicago City Council voted 13-30 Friday to reject a push to reverse Mayor Lori Lightfoot’s order that all city employees disclose whether they have been vaccinated against COVID-19 — and get fully vaccinated by Dec. 31.

David Krupa, a 19-year-old aldermanic candidate, alleges election fraud as he tries to take on Ald. Marty Quinn, a top ally of Illinois House Speaker Michael Madigan, in the 13th Ward.
