What commercial decking covers
Commercial deck work is a different trade discipline than residential. Where a residential deck is designed for 40 psf live load and 200 lb concentrated rail capacity, a commercial assembly occupancy carries 100 psf live load and significantly higher guard impact loads per Alberta Building Code Part 4. The surface needs to meet Class A flame spread (ASTM E84) when serving as a means of egress, the guards have to resist commercial impact loads, and public-use spaces have to meet ABC Part 3.8 barrier-free accessibility.
Our commercial service covers restaurant patios (the most common, especially along Canmore's Main Street and at Bow Valley resort properties), hotel terraces and pool decks, multi-residential common-area decks and balconies, and small commercial entry decks. We handle structural engineering coordination, drawing packages stamped for commercial review, Town of Canmore commercial permit submission, AGLC liaison for licensed patios where required, accessibility compliance, and final commercial inspection.
Who this is for
- Restaurant and bar owners rebuilding or expanding a patio
- Hotel and resort operators with terraces, pool decks, or guest-room balconies
- Multi-residential property managers with shared common-area decks
- Architects and general contractors needing a specialist commercial deck sub-trade
- Property owners receiving deficiency notices from a fire-code or accessibility inspection
- New commercial developments where the deck is part of the building permit
Our process
- Scope and feasibility review. Site visit with owner and (where applicable) architect or GC. We confirm occupancy classification, accessibility requirements, and structural scope.
- Drawing package and engineering. Stamped commercial drawings: plan, elevations, sections, framing, connection details, guard details, accessibility compliance. 2–3 weeks typical.
- Commercial permit submission. Town of Canmore commercial Building Permit + Development Permit if applicable. Parks Canada + Town of Banff for Banff projects. AGLC liaison for licensed patios.
- Construction phasing. Scheduled around operating hours - typically October–April for restaurants, in phases for hotels and multi-residential. Daily site cleanup, full safety compliance with WCB.
- Commercial inspection. Town inspector commercial sign-off, fire-code sign-off where required, AHJ accessibility verification.
- Warranty handoff. Lifetime workmanship guarantee on the substructure and connections; material warranties pass through (25–50 year composite, 20 year Duradek).
Material and substructure options
| Configuration | Best for | Substructure | Installed cost (per sq ft) |
|---|---|---|---|
| Composite over PT | Restaurant patios, hotel terraces | Engineered PT, 12" o.c., commercial fasteners | $185–235 |
| Duradek over plywood | Over-occupied-space decks, pool surrounds | Sloped plywood substrate, commercial membrane | $210–280 |
| Composite over steel | Long spans, second-storey terraces | W-section steel, engineered connections | $240–310 |
| Concrete with pavers on pedestals | Hotel rooftop terraces | Concrete slab, adjustable pedestal system | $220–300 |
| Full custom (kitchens, water features) | Premium restaurant patios | Engineered hybrid with mechanical and gas integration | $280–340+ |
What drives the cost
- Live load and engineering depth - 100 psf vs 40 psf residential roughly doubles framing material and connection cost.
- Accessibility scope - ramps, landings, handrails, and surface transitions for ABC 3.8 compliance add 8–15% to base price.
- Fire-code surface rating - Class A flame spread products carry a premium over standard residential composites.
- Off-hours scheduling - night and weekend work on operating restaurants/hotels adds 15–25% labour premium.
- Mechanical integration - gas lines, electrical for outdoor heaters, plumbing for water features all require sub-trade coordination.
Bow Valley local context - what's different here commercially
Bow Valley commercial decking carries the same alpine constraints as residential - 2.5 kPa snow load, 1.2 m frost depth, 1,400 m elevation with ~20% more UV than Calgary - layered onto commercial code requirements. Restaurant patios on Canmore's Main Street, in Spring Creek, and at Three Sisters resort properties experience high foot traffic year-round, which means we specify capped composite over standard composite (Trex Transcend Lineage and TimberTech AZEK Vintage are our defaults) and use stainless or hot-dip galvanized commercial fasteners that survive freeze-thaw cycling on a 365-day duty cycle. Hotel rooftop terraces require Duradek or another waterproof membrane system over a sloped substrate - we coordinate with the roofing trade so the warranty interface is clean.
For Banff commercial projects, Parks Canada and the Town of Banff Design Guidelines apply on top of the Alberta Building Code Part 4 commercial provisions - heritage-character properties along Banff Avenue have additional architectural review. AGLC licensing changes for patio expansions require coordination on enclosure and seating modifications, which we've handled for several Bow Valley restaurants. Our standing commercial general liability and WCB coverage support multi-trade commercial sites.
Why choose Canmore Deck Builders for commercial work
Same crew, same standard - scaled to commercial code
Our commercial decks are built by the same lead carpenters who run our high-end residential work, with engineering and material specs scaled up to commercial requirements. No "B-team" for commercial jobs, no offshored project management.
8+ years of Bow Valley commercial deck projects · zero failed commercial inspectionsPermit-clean commercial coordination
We handle the commercial Building Permit, the engineering stamp, accessibility review, fire-code surface ratings, and AGLC liaison where required. Single point of contact for the entire approvals process - saves your facilities manager a month of meetings.
Built around your operating schedule
Restaurant patio rebuilds in the off-season. Hotel terrace work in phases. Multi-residential common-area decks scheduled around tenant access. We've never shut down a Bow Valley operator's revenue for a deck rebuild and don't intend to start.
