Heated hearing: proposed ADU rules and minimum dwelling-size changes draw large public turnout

Commissioners spent the bulk of their July 21 meeting on two linked text amendments: one to allow secondary dwelling units (accessory dwelling units or ADUs) more broadly and another to replace fixed minimum dwelling sizes with standards from the International Property Maintenance Code.

Planning staff said the ADU proposal would permit two types of secondary dwelling units — detached backyard cottages and attached secondary suites — with a proposed maximum of 1,000 square feet (except in AR platted subdivisions) and rules to keep units subordinate in scale to the primary house. The staff presentation emphasized design guidance, a potential design competition, and a parking approach that could allow one additional off-street space but also rely on on-street permitting in some locations.

Public comment stretched over two hours and featured contrasting views. Opponents warned the change would undermine single-family neighborhoods, invite conversion by student housing investors, increase traffic and strain infrastructure, and raise enforcement challenges. "This is a muzzle loading firearm that's taking place tonight," one longtime resident said, urging delay. Supporters, including renters and nonprofit advocates, said smaller homes and ADUs would expand housing choices, enable aging-in-place, and increase housing supply. "Every garden cottage that a private property owner chooses to build on their own right ... gives another Athenian a safe place to live," one renter said.

Commissioners' positions varied: several asked for stronger guardrails — owner-occupancy limits, one-bedroom caps, parking and stormwater requirements, and homestead-exemption limits — or recommended remanding the ADU text back to the planning commission for more detailed criteria. By contrast, the companion amendment to remove rigid minimum dwelling sizes in favor of IPMC health-and-safety standards drew broader support from commissioners as a way to enable tiny homes while avoiding arbitrary square-foot rules that courts have struck down.

Why it matters: The ADU proposal and the minimum-size change each touch on housing affordability, neighborhood character, and zoning enforcement. The ADU proposal would be a significant change to how single-family lots can be used; the minimum-size amendment aims to enable smaller new units while preserving health and safety standards.

Next steps: Commissioners signaled varying approaches: remand ADU language for more detailed criteria, delay action until the incoming commission takes office, or deny and rewrite the proposal. The minimum-size amendment is more likely to advance rapidly because staff tied it to an adopted building code standard.
