Every pre-approved garden suite plan for Toronto and Mississauga, in one place.
Mississauga and Toronto publish helpful pre-approved garden suite plan PDFs. Those drawings answer what might be allowed. They do not deliver a built suite. Modular X sells the turnkey modular path: engineered design, factory build, crane set, and coordination through the municipal permit process.

Why Pre-Approved
How pre-approved plans can simplify your project
◆
The drawings already exist
The City has the building drawings. You do not pay a designer to redraw the suite.
◆
Reviewers look at your lot
Site plan, grading, trees, fire access — not the kitchen layout again.
◆
Soft costs and review time drop
The build does not get cheaper just because the PDF was free.
Finishes — siding, windows, doors, flooring — can change. Walls, doors, windows and room locations cannot, or you leave the pre-approved path.
Official plan catalogues
Start with the City drawings.
Mississauga
The City publishes a 40 m² / 430 sq ft studio and a 55 m² / 600 sq ft one-bedroom garden suite. Site and grading plans are still required. Review the official Mississauga pre-approved garden suite plans.
Toronto
The City publishes studio and two-bedroom garden and laneway suite designs. Changes including HVAC or plumbing can leave the pre-approved process. Review the official Toronto pre-approved garden and laneway suite plans.
The diagrams shown below are illustrative; official City drawings govern. Any modular adaptation requires designer and municipal review before relying on pre-approved status.
Check lot feasibilityCity PDFs vs Modular X turnkey
Pre-approved garden suite plans vs turnkey modular delivery
The City of Mississauga and the City of Toronto publish the building drawings as free PDF catalogues. That is a real head start — the building design is pre-reviewed against the Ontario Building Code and zoning. It is not a finished home. A free PDF still needs a lot to sit on, a permit to close, and a build to stand up. Modular X carries the free plan the rest of the way: site plan, grading, permits, construction, and inspections through to keys.
City PDF
What the City hands you for free.
- ·Building drawings — floor plans, elevations, sections
- ·Pre-reviewed against the Ontario Building Code and zoning
- ·No site plan, no grading plan, no permit, no foundation
- ·Nothing built. No inspections. No keys.
Modular X turnkey
A coordinated path from eligible drawings to keys.
- ◆Site plan, grading plan, tree forms — the lot file the City actually reviews
- ◆Building permit through ePlans, tracked to issuance
- ◆Factory / crane-in or site-built construction, subject to required design and municipal review
- ◆Inspections through final occupancy and keys
Crane-in proof
Built inside. Installed outside.
On lots that take a crane, we run the factory floor while the slab and services go in on site. One crane day. Catalogue-based modular work still needs designer and municipal review before relying on pre-approved status. Factory and jobsite footage only — we do not pass stock photos off as Modular X installs.

Two garden suite plans
The City publishes 40 m² / 430 sq ft studio and 55 m² / 600 sq ft one-bedroom plans. Verify current site requirements, application steps, and fees through official Mississauga sources.
One-Bedroom
600 sq ft
55 m² · A real second home
- ◆Separate bedroom
- ◆Full kitchen and living area
- ◆3-piece bath
- ◆The illustrated GTA one-bed turnkey around $310,000 is this scale of home — illustrative, not a quote
You still need a site plan and a grading plan. In ePlans you reference the model; you do not re-upload the City drawings. Current review timing and fees should be confirmed with the City for the specific application.

Mississauga does not have a laneway product. If the lot is in Toronto on a public lane, use the Toronto laneway plans below.
Toronto
Made-in-Toronto garden and laneway plans (2025 catalogue)
Pre-reviewed by Toronto Building for the Ontario Building Code and zoning. Reference the plan number — no re-review of the building design. Zoning on your lot is still site-specific. Development charge deferral may apply — a deferral, not a grant.
Studio Garden Suite
Studio
2025 catalogue · Compact backyard home
- ◆Open layout, 3-piece bath
- ◆Heat pump or forced air
- ◆Three fire-access configurations
- ◆Rear setback typically 1.5 m; separation from the house typically 4 m
Two-Bedroom Garden Suite
2-Bedroom
2025 catalogue · Room for a family
- ◆Two bedrooms, full kitchen, living
- ◆Same HVAC options
- ◆Same three fire-access options
Studio Laneway Suite
Studio
2025 catalogue · Fronts a public laneway
- ◆Rear setback typically 1 m, side 0 m on a blank wall
- ◆Separation 4 m if height ≤ 4 m; 7.5 m if taller (By-law 847-2025)

- ◆Three fire-access configurations
Two-Bedroom Laneway Suite
2-Bedroom
2025 catalogue · Family-sized laneway home
- ◆Two bedrooms + full living and kitchen
- ◆45–90 m fire path needs the extra City-accepted package (sprinkler / strobe / interconnected alarms or upgraded construction)
- ◆Heat pump or forced air
Whether a lot follows the garden-suite or laneway-suite path depends on its relationship to a public lane and the applicable City rules. Confirm current zoning, emergency-access, application, and fee requirements through official Toronto sources.

Straight talk
What a pre-approved plan does not do.
- ◆It does not skip the building permit.
- ◆It does not resolve site constraints such as trees, emergency access, grading, or utility conflicts.
- ◆It does not replace checking each municipality’s current process, requirements, and fees through official sources.
- ◆It does not make $310,000 a quote.
Build Method
Two ways we build the same plan.
Full custom on a catalogue layout
Catalogue-based and site-built, subject to site-specific design and municipal review.
Modular crane-in
Factory floor plus slab in parallel when the lot and reviewed design allow it. Crane access and municipal acceptance must be confirmed for the project.
When a catalogue plan will not fit: custom garden suite designs
Not every lot takes a catalogue plan. A pie-shaped lot, a heritage street, a tight lane, a mature tree in the wrong place, a grade change across the backyard — any one of those can rule out every model in the book. Custom design is the normal answer here, not an upsell.
What changes: a designer draws to your survey rather than to a standard footprint, and the building design goes through full municipal review instead of referencing a pre-approved plan number, which takes longer. What does not change: the site plan, grading, servicing and permit work are the same either way, and the same team runs the file.
Start at the lot check either way — the lot decides which path you are on.
FAQ
Questions we get on plans.
Which plan do I pick?
Mississauga: 430 if the backyard is tight, 600 if you want a real bedroom. Toronto: garden vs laneway is the lot, not a preference. Then studio vs two-bed.
Can I change the floor plan?
City catalogue restrictions determine which changes can stay on the pre-approved path. Changes to layouts, structure, building systems, or a modular adaptation require designer and municipal review before you rely on pre-approved status.
Do I still need a designer?
Yes, for site-specific work such as the site plan, grading, foundation, servicing, and any permitted adaptation. The City catalogue can reduce building-design work only when its requirements are followed.
What if I am in Brampton or Oakville?
Each municipality has its own current approval process and available resources. Start with feasibility, then verify the local requirements and catalogue status with official municipal sources.
Is this cheaper than custom?
Soft costs and review time, usually yes. The build is still a house.
Are these free garden suite plans from the City?
Yes — Mississauga and Toronto publish the building drawings. You still need a building permit, site plan, and grading. A free plan on a lot that fails fire access is still a no. Start at the lot check.
What is included in a free City garden suite PDF?
The City PDF provides pre-approved building drawings. It does not include the site plan, grading, foundation, services, permit coordination, factory build, crane set, inspections, or occupancy.
What does Modular X turnkey delivery add to a City plan?
Modular X carries the plan from lot feasibility through engineered site work, permits, factory construction, crane installation when access allows, on-site connections, inspections, and occupancy.
Are city PDF garden suite plans enough in the GTA?
No. A city PDF is a set of pre-approved building drawings, not a finished home. Across the GTA you still need a site plan, grading plan, permit coordination, foundation and services, factory build or site construction, crane set when access allows, and inspections through occupancy. The free PDF is research; turnkey delivery is the build.
Do you offer pre-approved garden suite plans?
Modular X can use eligible Mississauga and Toronto catalogue plans as the starting point. Site-specific design and any modular adaptation require designer and municipal review before pre-approved status can be relied on. We coordinate permits, construction, installation, inspections, and occupancy — not just drawings.
Do the Toronto plans include laneway suites?
Yes. The Toronto 2025 catalogue on this page includes studio and two-bedroom laneway suite plans as well as garden suite plans. Garden versus laneway is decided by the lot — whether it abuts a public lane — not by preference. Details: laneway suites in Toronto.
A free plan on a lot that fails fire access is still a failed lot.
