Second Storey Addition Permits in Ontario
A second storey addition is the most impactful way to add living space without reducing your yard. Sandhu Design Build handles the complete process — from structural feasibility assessment and permit drawings through to construction.
About Our Second Storey Addition Services
Adding a second storey is structurally complex and requires careful engineering. The existing foundation and first-floor framing must support the additional load, which typically requires a structural engineer's assessment. We coordinate this entire process, producing permit drawings that integrate the engineer's specifications with our architectural design. Our experience with GTA municipalities means we know exactly what each building department requires for a second storey addition application.

Our Process
Every second storey addition project begins with a free consultation. We visit your property, discuss your goals, review zoning and code requirements, and provide a detailed quote. Once you approve, our designer produces your permit drawings, we coordinate with any required engineers, and submit your complete permit application. After permit issuance, our construction team builds your project to the approved drawings, managing all trades and inspections through to completion and final occupancy.
