Hard cost ranges in Ottawa per square foot: office tenant fit-out $80-$250, new office building $200-$400, retail fit-out $75-$200, restaurant $200-$400, industrial warehouse...

Frequently Asked Questions

How much does commercial construction cost in Ottawa?

Costs range by type: office fit-outs $80-$250/sq ft, new office buildings $200-$400/sq ft, retail $75-$200/sq ft, restaurants $200-$400/sq ft, and industrial $80-$150/sq ft. Soft costs add 15-25% on top.

How long does a commercial construction project take?

Timelines vary: a 5,000 sq ft office fit-out takes 2-4 months. A new 20,000 sq ft commercial building takes 12-18 months. Add 3-6 months for design and permitting before construction.

Do I need special permits for commercial construction in Ottawa?

Yes. Commercial projects require building permits, may need Site Plan Control approval, and must comply with commercial building code, fire code, and accessibility standards. The permit process is more extensive than residential.

What is a performance bond in commercial construction?

A performance bond guarantees the contractor will complete the project as specified. If the contractor defaults, the bonding company pays to complete the work. Bonds typically cost 1-3% of the contract value.

Should I use a general contractor or construction manager?

Use a GC for well-defined projects with complete drawings — you get a fixed price. Use a CM for complex or evolving projects — you get expert management with more flexibility but less cost certainty.
