Your Kids Can't Afford to Buy. Your Parents Shouldn't Live Alone. There's a Better Way.

Ottawa's housing market has left families stretched thin. Adult children in Barrhaven and Orleans are paying $2,400/month in rent while their parents in Kanata and Nepean sit on significant home equity — and growing lonelier. Long commutes to check on aging parents. Grandkids growing up an hour away from grandma. Missing the moments that matter.

What if you could solve both problems with one project?

Coach Homes, In-Law Suites & Additions — Built for Your Family by Ottawa's Most Trusted Contractor

Thanks to Ontario's Bill 23, most residential lots now allow up to three units — your existing home, a secondary suite, and a coach home. OGC handles everything.

Bill 23 Eligible

Detached Coach Home / Garden Suite

From $250,000

A fully independent dwelling on your existing lot — separate entrance, full kitchen, private bathroom. Ideal for families with a large suburban or rural lot. Tarion warranty protected.

Best for: Large lots with space to build a separate structure

Most Popular

Home Addition with In-Law Suite

From $150,000

A self-contained wing added to your existing home with its own entrance and full amenities. Can be ground-level or a second storey addition. More affordable than a detached build.

Best for: Mid-size lots, tighter budgets, or families who want a shared wall

Most Affordable

Basement In-Law Suite Conversion

From $75,000

The most affordable multigenerational option — converting your existing basement footprint into a legal, comfortable in-law suite with separate entrance.

Best for: Families who want to get started quickly within a tighter budget

Price ranges are directional estimates based on Ottawa market norms. OGC will confirm your specific project pricing during your free consultation. All prices subject to final design and scope.

OGC has been building for Ottawa families for over 30 years. Here's what our clients say.

OGC made the whole process so easy. From the first consultation to move-in, they handled everything. My mother-in-law loves her new in-law suite — she has her independence and we have peace of mind.

Sarah T.

Kanata, ON

We weren't sure if our lot was big enough for a coach home. OGC came out, assessed everything, and presented us with three options. The design process was incredible — seeing the 3D walkthrough before construction started made all the difference.

Michael & Linda R.

Barrhaven, ON

We leveraged our home equity to build a basement suite for our son's family. OGC walked us through the financing options and delivered on time and on budget. Best investment we've ever made.
