Project Consultation and Scoping
We begin by understanding exactly what your Mississauga project requires.

For finished interiors, we explicitly document our structural assumptions on the drawings for verification by your contractor on site.

All drawings are coordinated with your architectural and HVAC drawings to ensure seamless permit submission.

FAQs
Frequently Asked Questions
Do I need a structural engineer for a renovation in Mississauga?
Yes, in most cases. Any modification to load-bearing walls, foundations, or structural systems in a Mississauga home requires engineering drawings stamped by a licensed Professional Engineer (P.Eng). This is a requirement of both the Ontario Building Code and the City of Mississauga’s building permit process. Beyond compliance, a licensed structural engineer ensures the design is safe and protects your home insurance coverage.
How long does it take to get a building permit in Mississauga?
The City of Mississauga building department typically responds to permit applications within 10 to 14 business days for smaller residential projects. Larger projects, such as additions or custom home builds, may take 4 to 6 weeks for an initial review. StrongBuilds handles any necessary drawing revisions promptly and at no additional charge for minor changes.
Can StrongBuilds help with basement underpinning in a Mississauga semi-detached home?
Absolutely. Semi-detached homes present specific challenges for basement lowering, including the shared party wall with your neighbour. We provide the structural designs, agreement templates, and permit documentation required for both full underpinning and benching solutions in Mississauga, including custom hybrid approaches when a neighbour agreement cannot be obtained.
What does a structural engineering package include for a Mississauga permit application?
A typical StrongBuilds permit package for a Mississauga project includes P.Eng-stamped structural drawings, structural calculations, Schedule 1 and general review forms, and any site-specific documentation required by the City of Mississauga. For complete permit packages, we also provide architectural, structural, and HVAC drawings in a coordinated set.
What is the difference between a structural engineering firm and a drafting service?
The Professional Engineers of Ontario authorize a licensed structural engineer to take professional responsibility for a structural design. Our P.Eng-stamped drawings are legally accepted by the City of Mississauga for permit applications and carry accountability for safety and code compliance. A drafting service cannot stamp structural drawings, cannot take professional responsibility for the design, and in many cases cannot represent you through the technical review process with the city’s building division.
Do I need a permit to remove a load-bearing wall in Mississauga?
Yes. The City of Mississauga requires a building permit for any wall removal, regardless of whether the wall is load-bearing. For load-bearing wall removals, a licensed engineer must design the replacement beam, columns, and supporting structure. StrongBuilds provides both the engineering design and the complete permit package to ensure your project is approved and structurally safe.
