Common Questions

Ottawa Construction FAQ

Direct answers regarding costs, permits, and timelines for homeowners in the National Capital Region.

How much does a General Contractor cost in Ottawa?

Costs for a general contractor in Ottawa depend heavily on the scope of work. For 2024-2025, a standard bathroom renovation typically ranges from $22,000 to $35,000, while a full kitchen renovation usually lands between $45,000 and $80,000. For larger projects like home additions, costs generally start at $325 per square foot. GCO provides fixed-price quotes to ensure you never pay more than the agreed amount.

Do I need a building permit for my renovation?

In Ottawa, a building permit is required if you are altering the structure (removing load-bearing walls), changing the plumbing systems, or adding square footage (additions). Cosmetic changes like painting, flooring, or replacing cabinetry usually do not require a permit. As a full-service Ottawa General Contractor, we handle all permit applications, zoning reviews, and inspections with the City of Ottawa on your behalf.

Which areas of Ottawa do you serve?

We provide general contracting services across the entire National Capital Region. Our primary service areas include Westboro, The Glebe, Hintonburg, Rockcliffe Park, Kanata, Stittsville, Orleans, and Manotick. We are familiar with the specific zoning overlays and heritage constraints in these historic neighborhoods.

What is the difference between a General Contractor and a Renovation Company?

A General Contractor manages the entire project lifecycle, including hiring specialized trades (electricians, plumbers), managing schedules, obtaining permits, and ensuring WSIB/insurance compliance. A renovation company may only focus on specific tasks (like flooring or painting). GCO acts as your single point of contact, ensuring complex projects involving structural engineering and multiple trades run smoothly.
