Custom Pergolas in Cochrane, Alberta
Arch & Bow designs and builds custom pergolas for homeowners in Cochrane, freestanding or attached to a deck. The Town's own permit-overview document, not Calgary's rules, is what tells us whether your specific design needs one.

Only if it's built to carry snow load. Cochrane's own permit overview exempts a pergola with no solid roof, no enclosed sides, and no snow-load-bearing design — meet all three and no permit applies, regardless of size.
Verified against the Town of Cochrane's Safety Codes Permit Information sheet, checked September 2026.
That last condition is the one worth reading closely: a pergola engineered to actually shed and carry Calgary-region snow loads — which is how we build every pergola we put up, chinook wind included — may fall outside that exemption on structural grounds alone, even with an open lattice roof. Cochrane's own document calls itself an overview, not an exhaustive rule set, so we confirm the specific classification with the Town's Safety Codes office before any Cochrane project starts, rather than assuming the exemption applies just because the roof looks open.
Why build for snow load if it might cost you the exemption?
Because the alternative is a pergola that looks fine until the first heavy, wet snowfall — Cochrane sees the same accumulation and sudden chinook wind uplift as Calgary, and a structure that can't handle either is a safety problem a permit exemption doesn't solve. See our cedar vs. aluminum comparison for how the two most common materials hold up, and our pergola permit guide for how Calgary's own thresholds compare.
