What is the C-O land use district in Calgary?

C-O is a Calgary land use district code — commercial — that appears on the municipal development record. What may lawfully be built on land carrying this code is set by Calgary's Land Use Bylaw 1P2007, which this platform does not reproduce; the pages here describe only the filings that carry the code.

How many development applications carry the C-O district?

8 development filings recorded on DevelopmentApplications.ca between 1979 and 2026 carry the C-O district as published by the City of Calgary. This counts filings in this platform's in-scope corpus, which excludes single homes, secondary suites, signs and routine relaxations — so it is smaller than a raw count of the City's own dataset.

What height is applied for on C-O sites in Calgary?

Across 8 filings carrying a site-specific height modifier on C-O, the median value applied for is 20 metres. Calgary appends these modifiers to the district code parcel by parcel, so the figure describes what applicants asked for on those specific parcels. It is not a district-wide height limit, and this platform does not publish the rules that apply to the district.

Site-specific modifiers seen on these filings

Our analysisCalgary writes these per parcel, so these are medians of what has been applied for — not limits the district sets.

Median height modifier

20 m

across 8 filings publishing an h modifier

Median floor area ratio

1.50

across 8 filings publishing an f modifier

Calgary publishes these as concatenated tokens — f2.0h14 is a floor area ratio of 2.0 and a 14 m height limit — with no legend. Reading f, h and d as floor area ratio, height in metres and units per hectare follows Bylaw 1P2007 and is held at 0.85 confidence because no planner has confirmed it. A median needs at least three values; where fewer exist, nothing is shown.

Historical comparisonBounded by what this platform has acquired.

The C-O record measured across records acquired from 1979 to 2026. This is not a statement about all development in Calgary — only about what these sources publish and what this platform retained. Redesignation counts cover the whole acquired corpus; filing counts and modifier medians cover the browsable slice only. They measure different populations. Calgary land use redesignation applications from 1982 and development permits from 1979.
