The answer
Possibly, but lot width alone does not decide it. Current zoning and transition status, intended uses, parcel geometry, title, access, servicing, policy, application requirements, municipal review, conditions, endorsement, legal plans, financing, demolition, and project economics all matter. A concept sketch or precedent is not an approval.
Calgary-specific context
Inner-city Calgary parcels can differ in lane access, utilities, covenants, corner context, trees, grade, and current district even on the same block.
What to do next
Run a survey, title, planning, servicing, and no-upside review before making subdivision value part of the purchase price.
