Questions

What a district does and does not tell you.

What does land use district CR20-C20/R20 mean in Calgary?

CR20-C20/R20 is Commercial - Residential Core in the Commercial - Core group under The City of Calgary Land Use Bylaw. The district sets what may be built and operated on a parcel. This page lists the 98 office building sites in the record whose parcel carries that district; it is not legal advice and the Bylaw itself governs.

Does the district describe the building or the land?

The land. A district is a legal rule attached to the parcel, so an older building may sit in a district that would now permit something quite different. That gap is exactly what makes the district worth reading beside the building record.

Boundary: Assessed values are the City’s assessment-roll figures for taxation and are not sale prices, asking rents, vacancy or availability; Alberta does not publish transaction prices. LiDAR heights are roof-surface elevations above the lowest ground point at the building perimeter and can differ from architectural heights. Storey equivalents are derived at 3.9 m per storey and are not floor counts. Distances are straight-line. Permit descriptions are the City’s records at retrieval and do not establish current use, tenancy or availability. Read the methodology.
