Foundation Type

If the site requires excavation or a new foundation, costs increase. Uneven or sloped lots may require additional work, adding to overall expenses.

Choice of Materials

Opting for high-end materials, such as custom cabinetry and hardwood flooring, raises costs. However, using reclaimed or eco-friendly materials can be a cost-effective alternative.

Permitting fees in Toronto range from $15,000 to $40,000. The complexity of the approval process can impact the total cost of the project.

Adhering to local zoning laws and building codes requires careful planning and can add costs. An expert contractor can help navigate these requirements efficiently.

Outdoor Enhancements

Landscaping elements, such as patios and gardens, enhance the livability of the unit but also add to the budget.

Smart Home Technology

Integrating automation systems like security cameras, lighting controls, and energy monitors increases
