Permit-ready residential drawings for renovations, additions, custom homes, structural changes, and municipal building permit submissions. We prepare coordinated architectural + structural drawing packages for clear review and construction.
Residential Building Permits: Clear, Review-Ready Drawing Packages
A residential building permit is often required when you renovate, add space, change the structure, finish a basement, build a deck, or make major layout changes. The City needs drawings that clearly explain the existing condition, proposed work, structural details, and how the project meets applicable code requirements.
GranDesign Engineering prepares residential building permit drawings that are practical for contractors and organized for municipal review. Our team supports homeowners, property owners, builders, and renovation professionals with permit-ready plans, structural drawings, and coordinated engineering details.
We are not a general contractor. We prepare the submission documents, including architectural drawings, structural engineering, and supporting coordination when required for your permit package.

What We Provide for Residential Building Permits
Every residential project has a different permit scope. A simple interior renovation may need layout drawings and structural notes, while a major renovation or custom home can require a larger coordinated package. We keep the drawings organized so reviewers understand the work and contractors can build from the plans with fewer questions.
- Residential building permit drawings for renovations, additions, custom homes, and structural changes
- Existing and proposed floor plans showing the project scope clearly
- Structural drawings for beams, lintels, posts, floor framing, roof framing, foundations, and load paths
- Foundation, footing, framing, and connection details when structural work is involved
- Coordination notes for HVAC, electrical, plumbing, grading, or survey documents when required
- Revisions and clarification responses if the municipality requests changes during permit review
If you are not sure what drawings your project needs, we can start by reviewing your renovation scope, photos, sketches, or existing plans to identify the right permit path.
Common Residential Permit Projects We Support
Residential permits can apply to many types of home projects. Some are mostly layout and code documentation, while others need detailed structural engineering. We help define the scope early so your drawings match what the municipality expects.
Renovations, Additions, and Custom Homes
We prepare drawings for major renovations, home additions, second-storey additions, garage conversions, custom homes, and projects where the existing house needs to connect safely with new work.
- Architectural permit drawings
- Structural framing and foundation details
Interior Structural Changes
If your project includes removing a load-bearing wall, adding a large opening, changing stairs, enlarging windows, or modifying framing, we provide the structural drawings needed for safe construction and permit review.
