Frequently Asked Questions

Can I build a home addition without a permit?

No. Constructing a home addition without the required permit may result in stop-work orders, fines, costly corrections, or the removal of unapproved work. Obtaining the proper permit before construction protects both your investment and your property’s value.

Many home additions require structural engineering drawings, especially when foundations, load-bearing walls, beams, roof structures, or second-floor additions are involved. Structural drawings ensure the addition meets Ontario Building Code requirements and is safe for occupancy.

Building permits are typically required for rear additions, side additions, second-floor additions, home extensions, sunrooms, enclosed porches, attached garages, and other projects that increase the size or structural footprint of a home.

Yes. We provide complete home addition permit services, including zoning review, architectural design, structural engineering, permit drawings, application submission, and communication with municipal reviewers until the permit is approved.
