At PROPlans, we prepare complete structural and architectural permit drawing packages for legal basement suites and secondary dwellings. Engineered to meet Ottawa's building department requirements and approved on the first submission.
Permit-ready drawings including floor plans, sections, details, and structural notes — one complete submission, no missing pieces.
We design your layout to meet Ontario Building Code requirements from the start — reducing the risk of rejection or redesign.
Detailed fire-rated assemblies, smoke/CO alarm layouts, and proper unit separation — everything required for legal occupancy.
We review your property against Ottawa zoning and flag issues early — so you avoid surprises after submission.
We know Ottawa Building Services requirements and flag zoning issues before they delay your permit.
Complete packages in 7–12 business days. Clear milestones so you always know where your drawings are.
Talk directly to the designer: fast answers, full accountability, no intermediaries.
One quote covers the full drawing package and submission, including municipality revision responses. No hourly billing.
