Laneway & Garden Suites in Toronto, Ontario
Toronto allows four units as-of-right — not six, despite what you've read. The 2025 rule change, real permit costs, and what a suite actually rents for.
Toronto permits four units as-of-right on residential lots city-wide, plus a laneway or garden suite in addition. Six units are permitted as-of-right in only nine of the city’s twenty-five wards — not across the city. There is no City cash grant for building one.
HouseLyft helps homeowners in Toronto, Ontario establish what their lot legally permits, what a suite will cost to build, what it should earn, and which programmes actually apply — then connects them with a vetted builder.
What Toronto permits on a residential lot
Four units as-of-right in Neighbourhoods-designated lands, covering RD, RS and RT zones. No rezoning, no Official Plan amendment, no public meeting. The provincial floor under Bill 23 is three units; Toronto exceeds it.
A garden or laneway suite in addition, permitted in R, RD, RS, RT and RM zones. A garden suite sits in the rear yard of a lot without laneway access; a laneway suite fronts onto a public lane.
No parking requirement for any of it, since February 2022.

The 2025 rule change most guides haven’t caught up with
By-law 849-2025 rewrote the garden suite rules, and the older summaries still circulating online are now wrong. What changed:
Angular planes were removed entirely.
The single most consequential change.
Read why →Angular planes were removed entirely.
The previous 45-degree limits from front, rear and side are gone. This is the single most consequential change — flat and shed roofs are now workable where they weren’t.
← BackThe 40% rear-yard footprint cap was removed
And the old total-floor-area rule with it.
Read why →The 40% rear-yard footprint cap was removed
, along with the old flat 60 m² total-floor-area rule.
← BackFloor area
Two storeys, one storey — and a ceiling tied to the house.
Read why →Floor area
is now 120 m² for a two-storey suite, 60 m² for one storey, and must be less than the main house’s floor area in every case.
← BackSeparation from the main house
Now set by how tall the suite is.
Read why →Separation from the main house
dropped to 4.0 m where the suite is 4.0 m tall or less, or 7.5 m where it’s taller.
← BackHeight
Buy height by standing further back.
Read why →Height
is 4.0 m if the suite sits less than 7.5 m from the house, rising to 6.3 m at 7.5 m or beyond.
← BackThe one that quietly disqualifies lots
It is Building Code, not zoning — so a variance cannot save it.
Read why →Firefighting access
— a maximum 45 m travel distance from the street to the suite entrance, at least 1.0 m wide with 2.1 m of clearance. That last one cannot be varied by a minor variance, and it quietly disqualifies some deep or tightly-built lots.
← BackRear yard setback is a minimum 1.5 m, more on deep lots. Soft landscaping must cover at least half the rear yard on lots wider than 6.0 m. Firefighting access is a Building Code requirement, not a zoning one — a maximum 45 m travel distance from the street to the suite entrance, at least 1.0 m wide with 2.1 m of clearance. That last one cannot be varied by a minor variance, and it quietly disqualifies some deep or tightly-built lots.
What the City actually charges
Toronto’s permit fees are assembled from rates rather than quoted as one number. From the City’s fee schedule effective January 1, 2026:
A 60 m² garden suite therefore starts around $1,814 in permit fees before any surcharges — that figure is arithmetic from the City’s published rates, not a City-published total.
The programme that isn’t a grant
This is where most advice goes wrong, so it’s worth being precise.
Toronto has no cash grant and no permit-fee reimbursement for building a secondary suite, laneway suite or garden suite. The City’s own Grants, Incentives & Rebates index lists no such construction grant.
What exists is development-charge relief, in three separate forms that are routinely conflated:
A City exemption
Development charges drop to $0 on the units that follow the first.
The detail →A City exemption
— development charges drop to $0 on the 2nd through 6th units of a project of up to six units on one parcel, effective July 24, 2025.
← BackA provincial statutory exemption
Not a City programme at all.
The detail →A provincial statutory exemption
— development charges do not apply to additional dwelling units created in existing or new residential buildings. This one is provincial legislation, not a City programme.
← BackA deferral
Twenty years — and then it is still there.
The detail →A deferral
for ancillary units not covered above — the charge is deferred for 20 years from permit issuance, calculated at the single-detached rate plus annual indexing.
← BackThat third one deserves care. A deferral is not forgiveness. The City’s programme page does not say the charge is ever waived. It becomes payable if a new lot is created by subdivision, condominium or severance within the 20 years, or if the property transfers without an assumption agreement in place. If you have read that the charge disappears provided the unit stays a rental, that condition does not exist in the programme.
What a Toronto suite earns
The number that matters for a new suite is turnover rent — what a new tenant pays — not what sitting tenants pay, since existing-tenant increases are capped by Ontario’s rent guideline.
CMHC, October 2025. A new suite lets at the turnover figure — the gap is what using the wrong one costs you.
Turnover rent, not the average
For the Toronto area in October 2025, CMHC recorded average turnover rents of $2,547 for a two-bedroom and $2,073 for a one-bedroom. Averages across all purpose-built rental apartments, including long-tenured units, were lower at $2,046 and $1,917 — which is why quoting the wrong one materially changes a payback calculation.
Those figures cover purpose-built rental apartments. Condominium rentals are surveyed separately and run higher.
What we do — and what we don’t
HouseLyft establishes whether a project stands up before anyone spends money on drawings: what your lot permits under the current by-law, what the build realistically costs, what it should rent for, and which programmes genuinely apply. Where it works, we hand you to a vetted builder and stay involved. Where it doesn’t, we say so.
We are not a lender and we do not sell mortgages.
One more correction worth carrying: the federal $80,000 Secondary Suite Loan is still advertised widely. It was cancelled in Budget 2025 and never launched. Our financing guide sets out what is actually live.
Serving Toronto and the surrounding region
We work across Toronto and the wider GTA, including Mississauga, Brampton, Markham and Vaughan — where the rules and the municipal programmes differ materially from Toronto’s. The full list is on our service areas page.

Common questions about Toronto suites
Only in nine of the city’s twenty-five wards — the eight Toronto & East York wards, plus Ward 23 (Scarborough North) as a pilot. Everywhere else the as-of-right maximum is four, plus a garden or laneway suite. Check your ward before you plan around six.
Not if the design sits within the by-law. The 2025 amendment removed the angular planes that used to force variances on otherwise reasonable designs, so more projects now comply outright. Firefighting access is the exception — it’s a Building Code requirement and cannot be varied.
No cash grant, no fee reimbursement. Development charges are already $0 on a secondary suite, and a deferral exists for some ancillary units — but a deferral is a timing benefit that eventually comes due, not money received.
They’re rate-based rather than flat. A 60 m² garden suite works out to roughly $1,814 from the City’s published rates. Interior basement work is charged differently, at $6.20 per m² for finishing.
Turnover rent, not average rent. A new suite is let at market to a new tenant — $2,547 for a two-bedroom in the Toronto area as of October 2025 — while the widely-quoted lower averages include long-tenured units whose rent is guideline-capped.
“Toronto allows sixplexes” — and why that costs money
Toronto allows sixplexes.
Four units city-wide. Six in nine wards of twenty-five.
Somewhere in the last year, “Toronto allows sixplexes” became something people repeat. It is not true for most of the city, and building a plan around it is an expensive way to find out.
Council did expand permissions — but geographically, and to nine wards out of twenty-five. Six units became as-of-right in the eight Toronto & East York wards plus Ward 23 (Scarborough North) as a pilot, adopted 25–26 June 2025 under Official Plan Amendment 818 and By-law 654-2025. Other wards can opt in; most have not.
Everywhere else, four units is the city-wide as-of-right maximum, set by the multiplex by-law Council adopted on 10 May 2023.
If your property sits outside those nine wards, a fifth or sixth unit means an application, a hearing, and a timeline measured in seasons rather than weeks. The four-unit permission plus a garden or laneway suite is where most Toronto projects actually live.
