Applying Toronto By-laws

Interpreting Toronto By-Laws for property line setbacks, principal residence separation, building height, shape, allowance for a second story, bike parking along with landscaping must be taken into consideration when creating design options for your build-able footprint.

Custom Design & Floor Plans

The goal is to create a Laneway House or Garden Suite Plan that will fulfill your objectives within existing By-laws. Major consideration is given to the intended use; Rental Unit, Family Dwelling or Office space. The plan or Accessory Dwelling Unit (ADU) must gain municipal approval.

Project Management

Once your plan has been approved, then the real work begins. Before the work starts a project timeline coordinating all the trades and inspections is required to make your build a success. Without proper Project Management it will be difficult to achieve a successful result.

Superior Construction

The required utilities and structural elements come first, followed by the exterior. Interior work; flooring, tiles, cabinetry, & doors, begins after all the wiring and plumping is installed. High-quality materials ensure your Laneway House or Garden Suite is built to last.

Our Process

We follow a structured process for every aspect of your Laneway House or Garden Suite project. Once the initial evaluation is completed, which focuses on intended use and site review, you are ready to move forward.

Site Review

Request a site review and one of our consultants will be in touch to set up an appointment. Our team will view your property and discuss your specific objectives, along with the City of Toronto’s requirements and incentive programs. Ballpark figures are available at this stage.


The next step is providing you with a comprehensive consultation that will lead to developing an architectural design with floor plans. If a site survey has been completed the consultation will be more effective. All documentation required for your permit application will be outlined at this time.


Combining the property site survey with your building requirements results in a quotation. It will include the design fee, permit application, and construction costs based on your requirements, with options if needed. The quotation comes with a budget bracket used for planning purposes.

Final Design

Completing the site survey and discussing all aspects of the Laneway House or Garden Suite leads to your build-able footprint on which the final architectural design and floor plan is created. This design is the culmination of all work done thus far and serves as the blueprint going forward.


Once you approve the final design and floor plans, they must be presented as a complete application to the City for permit approvals. Your application includes a group of documents that must be submitted as outlined during the consultation process.


After your application is approved and permits issued the construction work can begin. Project management determines the timeline or schedule for your project build. The goal is to complete construction within a 4-to-5-month window with minimal disruption to the neighborhood.
