AI is finally attacking the slowest line item in development: permits
Across Canadian cities, a mid-size project can sit in approvals for two to three years-longer than it takes to build. Vancouver modernist architect Arno Matis has lived that delay, and he's blunt: the approval timeline has ballooned as regulations got more complex and departments multiplied.
Blaming "gatekeepers" misses the point. The backlog comes from the stack of zoning bylaws, building and energy codes, and the manual work required to check every drawing against them. That's fertile ground for automation-if the tools can read plans and bylaws like a planner would.
Why the queue keeps growing
Checking compliance is tedious, rule-by-rule work: setbacks, height planes, site coverage, fire separations, energy details, and more. Plans are still 2D drawings. Regulations live as paragraphs, not machine-readable code. You can't just upload a PDF to a general-purpose AI and ask, "Are we compliant?"
To speed anything up, software must interpret drawings, parse bylaws, and map the two together at parcel level. That's the hard part-and it's exactly where new tools are focused.
Where AI fits right now
Matis's firm launched a partnership with Archistar to digitize these checks before submission, so teams can fix issues early and avoid endless resubmits. Archistar's platform reads zoning, building code and planning policies, and flags conflicts in context.
They're not alone. Symbium (San Francisco), GovStream.AI (Spokane) and CivCheck (Chicago) are building AI-based compliance engines and permit portals. The promise: fewer back-and-forths, tighter submissions, and planners spending their time on judgment calls instead of repetitive checks.
California sets the pace
State laws in California force faster approvals for standardized projects like rooftop solar and accessory dwelling units (ADUs). Cities have responded with online portals and automated checks that can issue a permit in minutes for simple, rule-based cases.
For reference, see the state's ADU guidance from California HCD and the California Energy Commission's Solar Permitting Guidebook, which both push cities toward streamlined, time-bound approvals.
Canadian pilots: progress with a human in the loop
Kelowna lets homeowners, contractors and builders apply through online portals where AI prompts for missing data and verifies details like setbacks. It still keeps a reviewer in the loop before issuing the permit.
Toronto is piloting a voluntary prescreen for any development type. Expect zoning-compliance feedback within hours instead of 10-30 days, with planners and code examiners completing the rest. The point isn't to replace people-it's to clear the bottlenecks.
The technical gap these tools must bridge
Software has to "read" bylaws and "see" drawings. That means converting written rules into structured logic, geolocating parcels, and extracting geometry from 2D PDFs. Then it must run checks like: Is the garage inside the side-yard setback? Does the garden suite meet lot coverage and height?
Do it well, and you front-load corrections before submission. Do it poorly, and you add noise and new cycles. Quality of data and standards matter.
What this means for developers, architects and builders
- Prescreen early: Run AI compliance checks before design milestones and before municipal submission. Catch zoning, setbacks, height, coverage and egress issues upfront.
- Standardize where you can: Use repeatable assemblies (e.g., rooftop solar kits, ADUs) that match pre-approved patterns. Standard projects see the biggest time savings.
- Submit data-rich drawings: Provide clean layers, consistent naming, and parcel-accurate surveys. Garbage in, garbage out applies here.
- Expect a human in the loop: Many cities will use AI to triage and verify, then a reviewer signs off. Plan your timelines accordingly.
- Design to local logic: Each municipality encodes rules a bit differently. Tune your templates and checklists per city to avoid auto-flags.
- Track deltas: When you revise drawings, keep a change log that maps to prior comments. It speeds rechecks-manual and automated.
- Train your team: A few hours on how portals interpret zoning and drawings can save weeks later. Make it part of onboarding.
Vendors and use cases to watch
- Archistar: Pre-submission zoning/building-code conformance and municipal deployments in B.C., Edmonton, and U.S. states.
- Symbium, GovStream.AI, CivCheck: Compliance engines and portals focused on rule-based permits and faster feedback loops.
- Municipal portals: Automated issuance for narrow, standardized scopes (rooftop solar, ADUs). Faster, cheaper, and predictable.
The bottom line
AI won't erase planning judgment-and it shouldn't. But it can compress the slow, repetitive checks that stall projects and tie up staff. As one planning scholar put it, reduce the box-checking so professionals can work at "the speed of common sense," without stripping the process of its human side.
Next step: If your pipeline includes housing, ADUs or standard solar, run a pilot on one project and measure time saved, resubmittals avoided, and error rates. Then roll the workflow to the rest of your portfolio.
