In Calgary, Alberta, property owners and neighbours can report buildings or structures that appear unsafe, abandoned, or at risk of collapse to city enforcement and building inspection teams. This guide explains who enforces dangerous-structure rules, how to file a formal complaint, what enforcement powers exist, and practical next steps to protect public safety. Use official complaint channels so the city can inspect and, where necessary, issue orders or take remedial action. For immediate reporting of hazardous structures, use the City’s unsafe-or-damaged buildings information and reporting guidance City of Calgary - Unsafe or damaged buildings[2].
