An inspection result is a record of one visit, not a verdict on the building. 37 of these 585 results are recorded as Not Acceptable. 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.

Not a tenant roster. The City licenses specific business types (retail, food service, personal services, contractors, wholesalers, schools and similar). Most office occupiers such as professional firms need no municipal licence and do not appear here. Matched by civic address and by licence location inside the parcel; home-based licences are excluded.

No individuals are named. The City issues many personal-service licences to people trading under their own name. Suite numbers are never published, and where a licence reads as an individual rather than an organisation the name is withheld and only the licence category is shown; 1 of the 13 licences on this parcel is withheld on that basis. Names of sources this site does not use are omitted.
