Where Can You Build a Sixplex in Toronto? The Nine As-of-Right Wards (2026)
The short answer: as of 2026, up to six units are permitted as-of-right on eligible detached-house lots in only nine of Toronto's twenty-five wards. In the rest of the city, the as-of-right limit is four units, subject to zoning. And in all nine of those wards, being allowed to build a sixplex is not the same as being able to — the ward gets you to the starting line; the specific lot decides whether six units actually fit and whether the project pencils.

Here's the policy, the nine wards, and the part that's easy to miss: why the ward is a boundary, not a green light.
Two different rules, two different years
Toronto changed its housing rules in two steps, and they're easy to blur together:
- Four units, citywide (2023). The City's multiplex framework permits up to four units as-of-right on most low-rise residential lots across Toronto — detached, semi-detached or townhouse — subject to zoning and applicable law.
- Six units, nine wards (June 2025). A later council decision extended as-of-right permission to six units — but only on eligible detached-house lots within nine named wards, under Zoning By-law 654-2025 and Official Plan Amendment 818, adopted in June 2025. The sixplex permission does not apply elsewhere, and it does not extend to semis or townhouses; extending it would take further Council-approved planning changes.
So "Toronto allows sixplexes" is half-true. Up to four units broadly, on most low-rise forms; five or six only on detached lots in nine wards. That distinction matters, because many lenders and insurance programs treat properties with five or more units as multi-unit/commercial underwriting — a different world from a four-unit residential build, though treatment varies by lender and product.
The nine wards
Up to six units may be permitted as-of-right on eligible detached-house lots in these nine wards. (Always confirm the current by-law and the exact boundaries before you rely on it — policy of this kind gets amended, and ward lines run down the middle of specific streets. The City publishes the official ward boundaries on toronto.ca.)
- Ward 4 — Parkdale–High Park
- Ward 9 — Davenport
- Ward 10 — Spadina–Fort York
- Ward 11 — University–Rosedale
- Ward 12 — Toronto–St. Paul's
- Ward 13 — Toronto Centre
- Ward 14 — Toronto–Danforth
- Ward 19 — Beaches–East York
- Ward 23 — Scarborough North
Eight of the nine sit in the old Toronto and East York district; Ward 23 (Scarborough North) is the lone suburban pilot. The sixplex permission doesn't extend to the rest of the city — that would take further Council-approved planning changes. And here's a first taste of the theme of this whole piece: the policy contemplates buildings up to four storeys, but the zoning controls the envelope through height and upper-storey stepbacks — not a four-storey cap. On many typical lots, the City's own 10.5-metre prototypes resolve as three storeys plus a basement. Permitted and buildable are already two different numbers — before you've even looked at a specific lot.
Permission is not feasibility
Here's where the ward-level answer stops being useful — and where feasibility begins.
Being in one of the nine wards means the six-unit framework may apply to your lot. It does not mean six units fit, or that the building is otherwise compliant or pencils. Between "permitted" and "buildable" sits a stack of lot-specific questions that no ward map can answer:
- Lot geometry. Frontage and depth, minus side and rear setbacks, determine the buildable envelope. On a narrow lot a full sixplex may not fit; some sites instead support a smaller main-building multiplex plus a qualifying garden or laneway suite — a separate planning, building-code and financing analysis, not automatically the sixth unit of a sixplex. In our own screening, below roughly 35 feet of frontage the unit plan — not the zoning — usually becomes the binding question.
- Overlays and specific zoning. The ward is the boundary; the actual zoning, heritage designations, and overlays run lot by lot and can quietly cap what you build.
- Trees, easements, servicing. A protected tree in the wrong corner, a registered easement on a shared driveway, or a servicing constraint can constrain the design, add cost, or reduce the unit count you can actually build — long before price is the issue.
- What's in the ground. On any lot with an existing or former structure, environmental status is unknown until it's investigated. That's a real cost and a real gate, not a formality.
A qualified zoning review is step one on any specific lot; where the ward map and the by-law differ, rely on the current by-law, official City mapping and qualified planning/legal advice. The map only tells you the search is worth starting.
So how do you actually evaluate a lot?
The sequence is the opposite of "find a ward, buy a house." It runs: confirm the lot can carry six units on paper (geometry), estimate supportable rents from recent comparable lease evidence (not asking prices), and test whether the numbers pencil under stated assumptions at a price you can actually pay — all before you commit to an address. Actual rents, costs, approvals and financing remain uncertain.
Permission is public and free. Whether a specific piece of dirt is worth the money it takes to investigate it properly is the real work, and it runs lot by lot, not ward by ward. That discipline is the difference between a buildable sixplex and an expensive lesson.
