Beyond policy: How AI and tech are removing barriers to Ontario multiplex and ADU development

In LandLogic’s article in the RESCON newsletter, we discuss how Ontario’s push to enable multiplexes and ADUs has unlocked new possibilities on paper, but real-world delivery has lagged behind policy ambition. Despite zoning reforms, builders and homeowners still face a maze of eligibility checks, fragmented bylaws, heritage overlays, and slow, unpredictable permitting processes. Determining whether a single property qualifies can take weeks, and even eligible projects are often derailed by paperwork, reviews, and compliance hurdles. The result is a growing gap between the promise of gentle density and the pace of actual construction, signaling that policy change alone is not enough.
AI and modern digital infrastructure are emerging as the missing link. By structuring scattered zoning, planning, and regulatory data, AI-powered tools can quickly screen properties, flag constraints, guide users through requirements, and catch issues early, dramatically reducing guesswork and delays. As permitting systems move online and data becomes standardized, builders gain clarity faster, municipalities receive cleaner submissions, and reviews become more efficient. For Ontario’s missing middle, this shift is transformative: projects that once stalled for months can begin moving in days. As adoption accelerates, AI is becoming a scalable path to turning multiplex and ADU policy into real homes on the ground.
