Trusted Ottawa Coach House Experts

Also known as carriage houses, laneway houses, even called Fonzie suites in some places – are small, detached units located on existing lots. They may be converted sheds or garages, or they may be purpose-built. Essentially, they are external apartments with a permanent foundation Coach houses are an innovative housing option aiming to diversify the makeup of neighborhoods, broadening the population base in terms of income levels and age demographics. For example, you could continue to live in the main house while staying close to your elderly parents who occupy a brand new, fully outfitted coach house. You could rent out the coach house in Ottawa to a young professional or student attending Carleton University, Algonquin College, or the University of Ottawa. If you are looking to downsize, you can rent out the main house to cover the mortgage and live a cozy life in the coach house designed to your exact specifications. This option is especially appealing for homeowners who want to maximize their rental income for purposes like paying off the mortgage, investing in retirement savings, building an education fund, or want extra “fun money” for vacations.

Coach houses in Ottawa are now approved under proposed new zoning bylaws – are you ready to make your dream of backyard living a reality?

Stylish coach house in Ottawa with a modern exterior and inviting front door.

New to Ottawa, coach houses come with many restrictions. This is why it is important to work with an experienced, licensed, insured contractor, not the lowest bidder. The last thing you want to do is investing a coach house only to discover that it doesn’t conform to the legal requirements regarding footprint, setbacks, access, and even design. And of course, once approval is finalized, any coach house must conform to Ontario Building Code provisions.

Even though a coach house covers a small footprint, it still has advanced utility needs. This is certainly not a DIY project or a job that should be handed to an unqualified jack-of-all-trades contractor. Whether building a structure from scratch or retrofitting a garage or shed, the coach house will require electricity, gas, water, and sewer/septic services installed with attention to detail and safety by qualified professionals. Furthermore to maximize the rental income and/or desirability of the space, all aspects of the design and construction must be handled with care.

Making us even more tempting is our online product showroom. Though we don’t sell any products these pages can help with your product selections while your in your own home. We have access to interior designers to help you match colours and fixtures bringing out the warmth and comfort you want your home to exude. Design work does come with extra fees, but well worth it when it comes to the final look of the finished product.

You deserve a state-of-the-art coach house built by the professionals.

Frequently Asked Questions



HOW MUCH DOES IT COST TO BUILD A COACH HOUSE?

The cost of a coach house depends on the extent of the coach house and the materials you choose. If you’re looking to build a 500 SF coach house, you should estimate on a cost of $200,000 (400 psf)



HOW LONG DOES IT TAKE TO BUILD A COACH HOUSE?

A 500 SF coach house typically takes 3-4 months to build.



CAN I BUILD MY COACH HOUSE MYSELF?

You always have the option of building your coach house yourself, however, we advise against it. If you are lacking prior experience and are simply looking for something cost-effective, there are better alternatives, such as renovating during the low season. By hiring a professional, you avoid having to pay for any repairs or replacements in the future.



DO I NEED A PERMIT TO BUILD A COACH HOUSE?

Permits are required to build a coach house. A building permit will be needed from the City of Ottawa and an electrical permit from the Electrical Safety Authority (ESA). Architectural/Design plans will also be needed.



WHEN IS THE BEST TIME TO BUILD A COACH HOUSE?

Like most renovations, the best time to build a coach house is at the start of the summer months. With that said, a coach house can be started later in the summer or even the fall as long as it gets closed in before it gets too cold or snowed in.



WHAT IS THE MOST EXPENSIVE PART OF BUILDING A COACH HOUSE?

If you are building a coach house, the foundation/concrete slab and architectural/design fees are usually the largest expense. Discussing your budget with a renovation expert will give you a better idea of what you can afford and the steps you can take to minimize the cost.



DO I NEED A PLAN FOR MY COACH HOUSE?

Yes, Architectural/Design plans are needed for any coach house. If you don’t have an exact plan in mind of what you are looking for, we’re happy to help! Our team is more than willing to provide direction and ideas on what will suit your space best.

Wheelchair accessible bathroom. I had a big renovation job of my bathroom and Keith and Clavil were great! We have a beautiful accessible bathroom now. Keith was great with ideas and suggestions when I was unsure of what to do. The work is high quality and I felt at ease with them in my home for the length of the project. Even Keith’s wife helped with the painting which was perfect! They cleaned up and took away the garbage so I want left with it. Thank you for this amazing space. You have given us something we never thought was possible!
Highly recommend this company!

With my new ensuite bathroom, I couldn’t be happier. I adore my new shower and my standalone soaking tub, which is a dream come true for bathing. Clavil and Mike did an outstanding job, and Keith made sure everything went without a hitch. I heartily urge anyone wishing to renovate to check out Renosgroup.
