The zoning categories the permits on Cosburn Ave fall in, under Zoning By-law 569-2013. These are the City's own category names. This counts permits, not land: it says where the building work happened under which rules, not how the area is carved up. What each zone allows, and what gets built in it.

Some projects on Cosburn Ave need the Committee of Adjustment to approve a minor variance from the zoning by-law before a building permit can be applied for at all. Where that applies, the committee’s clock runs first and the permit wait above starts only once it has stopped. Back to back, that is about 185 days, not the 25 days the permit figure alone suggests. How variances work, and the approval rates.
