Tiny Homes in Barrhaven
A permanent, permitted tiny home behind your Barrhaven house, whether it is a detached home, a semi, or a townhouse.
A Tiny Home Behind Your Barrhaven House
Barrhaven homeowners usually come to us with a family reason: a parent who wants to live close by, an adult child who wants independence without moving across the city, or a tenant to help with the mortgage.
If your Barrhaven home is a semi or a townhouse, that does not rule a tiny home out. The City allows a coach house on lots with a detached, linked-detached, semi-detached, townhouse, or duplex dwelling, so what decides it is the rear yard: setbacks, lot coverage, and a route for services and equipment. If you are planning a whole new house instead, see our custom home builders in Barrhaven page.
In Ottawa, a permanent tiny home on a lot that already has a house is a coach house: a detached dwelling on a foundation, built to the Ontario Building Code under a building permit. OGC designs and builds them on the lot you own. See our tiny homes in Ottawa overview, or the full coach house rules.
- Detached, semi, and townhouse lots assessed
- Rear yard access and setbacks checked first
- Services run from the main house
- Backed by a 7-year warranty
What a Tiny Home Takes in Barrhaven
Five steps from the lot check to the keys, whatever kind of house is in front.
We confirm what your property allows: unit count, rear yard setbacks, lot coverage, and the permitted size. On a semi or townhouse lot we look closely at how equipment and the service trench will reach the back yard.
- Unit count and size limits confirmed
- Setbacks, lot coverage, and amenity space
- Servicing route from the main house
- Site access, trees, and grading reviewed
Start from one of our ready-to-build floor plans or design from scratch to suit your rear yard. You see the result in 3D before anything is built.
- Floor plans within the permitted footprint
- Full 3D renderings inside and out
- Exterior matched to the main house or set apart from it
- Finish selection with your designer
A permanent tiny home is a new dwelling, so it needs a City of Ottawa building permit, engineered drawings, and a site plan. If the design cannot meet the by-law exactly, a minor variance at the Committee of Adjustment comes first and adds months, and we tell you that up front. Read our guide to tiny home permits in Ottawa.
- Permit drawings and structural engineering
- Site plan, servicing, and grading
- Minor variance handled if the lot needs one
- Fixed-price contract before anything is ordered
Water, sewer, and hydro are trenched from the main house to the back yard, sometimes with a service upgrade at the house. Then the footings and foundation go in.
- Service trench and connections
- Panel upgrade at the main house if needed
- Footings and foundation sized for the soil
- Yard protection and restoration planned in
Framing, close-in, mechanical, and interior finishes, then every municipal inspection through to occupancy. One project manager runs the whole build, and the finished tiny home carries OGC's 7-year warranty.
- Framing, roof, windows, and cladding
- Kitchen, bathroom, flooring, and trim
- All inspections managed through to occupancy
- Final walkthrough and 7-year warranty

Why Barrhaven Homeowners Choose OGC
200+ verified reviews across Google, Houzz, and HomeStars, and the team behind Ottawa's first coach house.
Ottawa's First Coach House Builder
OGC built the first coach house in Ottawa under the city's coach house rules, the Spadina in Hintonburg. We learned the process on our own project, not on yours, and we have been designing and permitting backyard homes here ever since.
Award-Nominated, Industry Members
The Spadina was nominated for a Greater Ottawa Home Builders' Association award. OGC is a member of the GOHBA, RenoMark, and the Canadian Home Builders' Association, and our work has been covered on CTV and CBC.
True Design-Build, One Roof
Design, engineering, permits, site plan, servicing, and construction all live in-house. No gap between the person who drew your tiny home and the person who has to build it in your back yard.
See It Before We Build It
Every tiny home is designed in 3D so you can walk through it before a footing is poured. In a small building that matters more, because there is no spare space to fix a layout you dislike later.
Fixed Pricing, No Surprises
What you are quoted is what you pay, including the servicing trench and the site work that cheaper quotes leave out. No hidden fees and no mid-project change orders.
7-Year Warranty
A tiny home is a whole building, and it is backed by OGC's 7-year warranty. A parent, an adult child, or a tenant will be living in it, so it is built to last.
What a Tiny Home Costs in Barrhaven
These are the ranges OGC publishes for a permanent tiny home. Where a Barrhaven build lands depends on size, finish, and the site.
Rear Yard Access
On a semi or townhouse lot, the route to the back yard can be narrow, which can mean smaller equipment and a longer servicing run. We confirm it on site and price it in from the start.
Size and Layout
A kitchen and a bathroom cost what they cost whether the building is 500 square feet or 5,000, so a tiny home carries a high cost per square foot by nature. Going from one bedroom to two, or adding a second bathroom, moves the number more than floor area alone.
Approvals and Timeline
A design that fits the by-law goes straight to a building permit. One that needs a minor variance goes to the Committee of Adjustment first, which adds months and cost. We design to avoid that wherever the lot allows, and tell you up front when it is unavoidable.

Barrhaven Tiny Home Questions
On most fully serviced lots, yes, built as a coach house. Current zoning reliably supports three dwelling units on a serviced lot, and the four-unit change is still under appeal. Setbacks, lot coverage, and access to the rear yard decide the rest, and we check them before design.
The Ottawa range applies: $250,000 to $350,000 or more for a permanent tiny home, depending on size, bedrooms, finish level, and servicing. Rear yard access is the main site variable. See our tiny home cost guide.
While both of Ottawa's zoning by-laws apply, design to the smaller cap, about 80 m² (861 sq ft). Lot coverage and rear yard amenity space then decide how that area is laid out.
Permanent tiny homes on the lot you own: designed for your property, permitted, built on a foundation, and finished to the Ontario Building Code. If you are comparing a factory-built or wheeled unit, budget for the site work it still needs, including grading, a foundation or pad, and water, sewer, and hydro, which our cost guide puts at about $50,000 to $150,000 or more.
Yes, where the lot allows it. The City permits a coach house on lots with a detached, linked-detached, semi-detached, townhouse, or duplex dwelling. Whether yours qualifies comes down to rear yard setbacks, lot coverage, and access for services and equipment, which we check before design.
