How much does it cost to apply stucco to a commercial building facade in Ottawa?

Commercial stucco projects in Ottawa are a different beast from residential work — larger scale, stricter code requirements, and more complex logistics. For a typical commercial facade, budget between $14 and $28 per square foot installed, with most Ottawa commercial projects landing in the $18–$24 range for a complete EIFS or traditional stucco system.

Cost ranges by system type

Traditional three-coat stucco (over metal lath): $14–$22/sq ft

This includes metal lath, scratch coat, brown coat, and finish coat. Traditional stucco is extremely durable and preferred for ground-level commercial facades in Ottawa where impact resistance matters — think retail storefronts and restaurant exteriors.

EIFS (Exterior Insulation and Finish System): $18–$28/sq ft

EIFS is the dominant choice for Ottawa commercial buildings because it combines insulation and finish in one system. Under the Ontario Building Code, commercial EIFS installations must meet SB-10 energy efficiency requirements, and the insulation value of EIFS often helps meet those targets cost-effectively. A drainable EIFS system (now standard in Ottawa) includes a drainage plane behind the insulation board.

Typical commercial project totals:

• Small retail storefront (500–1,000 sq ft): $10,000–$25,000- Mid-size commercial building (2,000–5,000 sq ft): $40,000–$120,000- Large multi-storey facade (5,000–15,000 sq ft): $100,000–$350,000+

What drives commercial costs higher than residential:

• Scaffolding and access: Multi-storey commercial buildings require engineered scaffolding systems, often $5,000–$20,000+ depending on height and building footprint. Swing stages for tall buildings add further cost.- Engineering and permits: Commercial stucco in Ottawa requires building permits and often stamped engineering drawings for the cladding attachment system. Budget $3,000–$8,000 for engineering, permits, and inspections.- Fire ratings: The Ontario Building Code requires specific fire resistance ratings for commercial cladding systems depending on building size and proximity to property lines. Non-combustible stucco systems may be required, which limits material choices.- WSIB and insurance: All commercial stucco contractors must carry WSIB coverage and commercial liability insurance (minimum $2M for most general contractors). These costs are built into their pricing.

Timing is critical for commercial stucco in Ottawa. The application window is May through October, and large commercial projects often need to be phased across the facade to maintain building access for tenants. Winter enclosures and heating are possible but add 30–50% to labour costs.

Get at least three bids from contractors experienced in commercial-scale stucco. Ask for references on Ottawa commercial projects specifically — commercial stucco requires different skills and equipment than residential work, and not all residential stucco contractors can scale up effectively.
