Building Permit Drawings for Every Toronto Project
Every construction project is different-and so are its permit requirements.
The City of Toronto has specific building permit application requirements based on the type and scope of work being proposed. Whether you're building a backyard garage, renovating a century-old home, creating a legal secondary suite, or fitting out a new commercial space, submitting complete and accurate permit drawings is one of the most important steps toward obtaining approval.
At Ontario Design Studio, we prepare BCIN-certified architectural drawings for virtually every building permit category recognized by the City of Toronto. Our drawing packages are tailored to your project and prepared to comply with the Ontario Building Code, applicable zoning by-laws, and municipal submission requirements.
We proudly work with:
"Our services cover everything from small residential renovations to complex multi-unit residential and commercial developments."

Whether you're improving your existing home or building something entirely new, we prepare permit drawings for a wide range of residential projects throughout Toronto.

Residential Demolition & Replacement
If your project involves demolishing an existing house before constructing a new one, the City of Toronto requires separate documentation for both the demolition and replacement building. Our team prepares coordinated drawing packages that support the entire process.
Basement Underpinning
Many Toronto homes have basements with limited ceiling height. Underpinning allows homeowners to safely lower the basement floor, creating additional living space while strengthening the existing foundation.
