FAQ
Do you include stamp with the drawings?
Yes, the stamp is included in the Standard and Premium packages. I collaborate with certified Ontario engineers to ensure full OBC compliance and permit approval.

Yes. All drawings are prepared according to the Ontario Building Code (OBC) and formatted for submission in any Ontario municipality.
