Renovation Drawings & Home Addition Plans
Permit-Ready Renovation Drawings & Addition Plans
CanaCore coordinates verified drafting specialists to produce renovation drawings and home addition plans — code-compliant floor plans, sections, and details prepared for municipal permit review, from kitchen remodels and basement finishes to second-storey additions.
What Are Renovation Permit Drawings?
Renovation permit drawings are technical documents showing proposed changes to existing structures. Unlike new construction plans, renovation drawings must clearly indicate what's existing versus what's new, demonstrate code compliance for modified areas, and show how changes integrate with the original building. Most municipalities require permits for kitchen and bathroom remodels, structural changes, basement finishing, and any work affecting plumbing, electrical, or HVAC systems. Our drawings ensure your renovation meets all code requirements for safe, legal construction.

Common questions
How do you keep a renovation project on schedule?
By sequencing the work around the inspection hold points and the long-lead items, and by coordinating the verified, field-supervised trades so one stage is ready when the last finishes. Most delays come from supply and from surprises found on opening up, not from labour.
What is included when CanaCore manages a renovation?
CanaCore coordinates the verified contractors, sequences the trades and supervises the work in the field, and organizes the drawings for permit review where the scope needs them. The company organizes and oversees the project rather than performing the trades itself.
What happens if the scope changes partway through?
Opening up walls or floors can reveal conditions the plan did not show, and additions to scope happen. Each change is priced and, where structural, engineered before it proceeds, so the budget and schedule stay tied to what is actually being built.
