The answer
The City states a demolition permit is required when demolishing or moving a building, for partial building demolition, or for reducing a building to its foundation and rebuilding. The file can also involve service disconnections, tree disclosure, asbestos, heritage review, site fencing, public safety, accessory structures, occupancy, and sequencing with the new project.
Calgary-specific context
Do not remove a Calgary home because a redevelopment concept exists; financing, insurance, approvals, vacancy, taxes, and site carrying costs can change once the building is gone.
What to do next
Map permit prerequisites, hazardous-material work, utility disconnections, insurance, site protection, and the approved replacement path before demolition.
