What is the ROI on adding a second storey to an Ottawa bungalow in today's market?

Adding a second storey to a bungalow is one of the biggest renovations you can take on. Many people want to know what share of the cost they would get back at resale. There is no reliable published return figure for second-storey additions in Ottawa, and any single percentage you see depends heavily on the street, the house and the market at the time you sell. It is better to understand what pushes value up or down and to get local advice before you commit.

Start with real numbers for your house. As broad perspective, a full second storey over a bungalow can range from roughly $275,000 to $400,000 depending on size, structure and finishes. Treat that as perspective, not a quote. A local real estate appraiser or agent can tell you what comparable two-storey homes on your street have sold for, which is the only grounded way to estimate the value side.

Quality and fit drive value. An addition that blends with the original architecture, has a sensible floor plan and meets current energy rules tends to be valued well. One that looks tacked on, uses budget finishes or creates an awkward layout can hold value back. Under SB-12, an addition must meet a compliance package or the addition table, which includes an attic ceiling at R-60 and above-grade walls at R-19 plus R-5 continuous insulation.

Features buyers look for. An upper-floor primary suite with its own bathroom, good closet space, a second full bathroom for the other bedrooms and upper-floor laundry are common requests in larger homes. Ask your designer which of these fit your footprint.

Staying versus moving. Building up avoids the costs of selling and buying, such as land transfer tax, commissions, legal fees and moving, and you keep your lot, neighbourhood and school catchment. Those savings are real, but they depend on the prices involved, so ask your lawyer or agent to run them for your case.

Tax questions. If the home is your principal residence, or if you plan a secondary unit with rental income, ask an accountant how the addition affects your situation.

Don't forget the structure. The existing foundation must carry the new floor. A structural engineer will confirm whether reinforcement is needed, and that answer can change the cost a lot.
