Initial consultation
1-2 hoursMeet with drafter or architect to discuss your goals, budget, and timeline. Bring photos, sketches, and measurements if you have them. Discuss scope: permit drawings only, or design services included. Clarify who handles structural engineering (some drafters coordinate, others leave it to you).
Site measurement
2-4 hours on siteDrafter visits your property to measure existing conditions. They record room dimensions, ceiling heights, window/door locations, electrical panel, plumbing stack, HVAC equipment. Older homes may not be square or plumb — accurate measurements prevent surprises during construction. Bring your survey if you have one (shows property boundaries and setbacks).
Concept design
1-3 weeksDrafter produces initial floor plans and elevations showing proposed changes. This stage is iterative — expect 2-3 rounds of revisions to refine layout, confirm dimensions, and adjust based on your feedback. Good time to check zoning compliance (setbacks, lot coverage, height). If project violates zoning, you need a variance before proceeding to permit drawings.
Structural coordination
1-2 weeksIf removing load-bearing walls or altering structure, drafter sends plans to structural engineer. Engineer calculates beam sizes, specifies footings, details connections. Engineer provides stamped drawings and calculations (you pay engineer separately). Drafter incorporates structural details into permit set.
Permit drawings
1-2 weeksDrafter finalizes construction drawings to municipal standards: floor plans, elevations, sections, site plan, details. Drawings include dimensions, materials, insulation values, code notes. Some municipalities require energy compliance forms (SB-10 in Toronto). Drafter packages drawings for permit submission.
Permit submission and revisions
1-2 weeks for revisions (permit review itself takes 4-8 weeks)You or your contractor submits drawings to building department. Plan examiners review for code compliance and often request revisions (clarify dimensions, add details, show fire separation). Drafter makes revisions and resubmits. Most projects need one revision round. Complex projects may need two.
Construction support
As needed during constructionDuring construction, contractors may request clarifications or field changes. Some drafters include one revision round in their fee. Major changes (relocating stairs, adding square footage) cost extra. Keep drafter's contact info for your contractor.

Money-Saving Tips
BCIN designer costs 30-50% less than a full architect for permit drawings — same legal authority for Part 9 buildings.
Get a site survey before starting design — assumptions about lot size create expensive redesigns.
Provide a clear wish list before the first meeting — design changes after drawings start cost $200-$500 per round.
Ask for digital files (DWG/PDF) — you'll need them for contractor bidding and permit applications.
Structural drawings are separate from architectural — budget for both on additions and underpinning.
