Permit Drawings in Ontario
Simplified, Accurate, and Approved
Why Permit Drawings Are Important
In Ontario, most construction projects—whether it’s a basement apartment, house extension, or garden suite—require permit drawings before any work can begin. These drawings are more than just sketches; they are detailed plans that show how your project will meet the Ontario Building Code and local municipal requirements. Without them, your project cannot move forward legally.
