An inspection result is a record of one visit, not a verdict on the building. In the City's process a Not Acceptable result is an ordinary step: the inspector lists what must change and the work is re-inspected, which is why the most common outcome across the record is Acceptable Add Inspection. Most results relate to a single tenant improvement rather than the whole building. Inspector notes are The City of Calgary's own text at retrieval, with contact details removed; applicant and contractor names are never read.
