From day one: Ald. Lawson on Chicago's ADU ordinance, the pilot's lessons, and what comes next
Published on May. 9, 2026 by Steven Vance
When Bennett Lawson was sworn in as 44th Ward alderman, he introduced three ordinances on his first day. One was a speed limit reduction. One was a small business initiative. The third was a citywide ADU ordinance — no restrictions.
"I did it more as a value statement," he told Mark Ainley and Tom Shallcross on a recent episode of the Straight Up Chicago Investor podcast. But it turned out to be a preview.
Lawson had been chief of staff to the zoning committee under Chairman Tom Tunney when the city launched its ADU pilot program — the 2021 experiment that limited accessory dwelling units to select wards and residential zoning only. He watched it produce 418 permitted units over roughly five years, mostly interior conversions. Not a transformational number, but enough to prove demand.
The permanent, citywide ADU ordinance took effect April 1, 2026. Within two days, 188 applications had been submitted.

The biggest structural difference is the addition of B and C commercial zoning. The pilot was residential-only. Under the permanent ordinance, mixed-use properties on commercial corridors can now add ADUs — including conversions of underused commercial space on upper floors. Lawson described a chiropractor in his ward with a first-floor practice, a second-floor office, and apartments above — who plans to convert that second-floor office to residential now that he no longer needs it. That conversion wasn't possible under the pilot.
The parking requirement that once blocked many would-be ADU owners — particularly in dense, transit-served neighborhoods where providing a dedicated space is impractical — has also been resolved.
One remaining constraint: the city's affordability requirements applies to a second ADU that gets built (for situations where more than one ADU is allowed). The first is market rate; the second must be rented affordably. Lawson acknowledged this limits bulk conversions on larger courtyard buildings but said he'd like to revisit it in a future term.
What ADUs can and can't do
Lawson was direct about scope. "I'm not naive to think this is going to be transformational," he said. He frames ADUs as part of a broader shift in how Chicago aldermen are thinking about density — away from single-family and high-rise towers and toward what he calls the "missing middle."
"The three-flat is the workhorse of urban density," he said, pointing to his own ward as evidence that density and livability aren't in conflict.
