Custom Coach House Construction in Ottawa
In Ottawa, homeowners often build coach houses to add rental income, housing for family, or a home office separate from the main dwelling.1 This page covers coach house construction from permits through framing, utilities, and finishes. KV Construction provides free quotes and works year-round across Ottawa, Stanley Corners, and Franktown. As a Red Seal carpenter and general contractor, we handle permits, foundation, and finishes.
Before you break ground on a coach house in Westboro, the Glebe, or Ficko, you need to know if your lot qualifies. Ottawa's Zoning By-law 2008-250 limits coach house size to 40% of your main house footprint and 40% of the yard. Many older neighborhoods require Committee of Adjustment approval for setback relief. We measure your site, review zoning rules, and file minor variance applications. This prevents costly design changes or denied permits. Learn more about our construction services.
Zoning and Permit Requirements Shape Every Coach House Project in Ottawa
Separate Utilities and Services Make Coach Houses Fully Self-Contained
If you're building a rental coach house in Stanley Corners or Barrhaven, you can install independent electrical and gas meters to simplify tenant billing. However, coach houses must connect to your main dwelling's water and sewer services in urban Ottawa. Enbridge Gas and Hydro Ottawa require new service applications. We file utility applications during permitting. Rough-in inspections happen before insulation. Final connections are made after drywall and trim are installed.
Families in Kanata or Franktown often build coach houses for aging parents or adult children. Investors focus on maximizing rental yield. Most Ottawa coach houses range from 600 to 900 square feet. Right-sizing balances construction cost with rental rates and long-term property value. Ottawa's freeze-thaw cycles require durable exterior materials and quality insulation. We design custom layouts with open-concept living, stackable laundry, and 9-foot ceilings. Material selections meet R-value targets for Ottawa's climate.
Size, Layout, and Material Choices Determine Coach House Livability and ROI
Phased inspections keep the project in compliance with code and on schedule. Ottawa soil conditions include clay and seasonal water tables. Engineered footings and weeping tile are often required. Winter concrete pours need heated enclosures. Excavation and frost-wall foundation take 2 to 3 weeks. Framing and roof deck take 2 weeks. Windows, siding, and roofing take another 2 weeks. Interior trades follow after weatherproofing.

Final Inspections and Occupancy Permits Ensure the Coach House Meets Code
Property owners in Stittsville or Manotick nearing completion of their coach house project need to prepare for tenant move-in or family occupancy. Passing all Building Code inspections unlocks the occupancy permit required before anyone lives in the new coach house. City of Ottawa inspectors verify fire-rated drywall between units, egress windows in bedrooms, and smoke and CO detectors on every floor. HVAC, plumbing, electrical, and fire separation all get reviewed. We walk through everything with you, handle punch-list corrections, and coordinate final sign-off.
Investors in Orleans, Barrhaven, or Ficko often monetize coach houses through rentals. Meeting Residential Tenancies Act standards protects you from fines. Ottawa's Rental Housing Property Management By-law requires tenant information packages and timely service responses. Short-term rentals like Airbnb require city permits. You must maintain smoke alarms, handrails, and exits to property standards. We build coach houses that meet all Building Code requirements.
