Ottawa's established neighbourhoods are undergoing a quiet but unmistakable transformation in 2026, as infill housing, particularly the slender, multi-storey homes known as "skinny homes", continue to reshape streetscapes from Hintonburg to Hunt Club.
What Is Infill Housing?
Infill development refers to new construction built on vacant or underutilized lots within already-developed areas, rather than on the urban fringe. In Ottawa, this most often takes the form of lot severances, splitting a single large residential lot into two or more parcels, followed by the construction of new homes on each newly created lot.
The result is the rise of the skinny home: a narrow, two- or three-storey structure, often under 20 feet wide, squeezed onto a severed lot between older, more traditional houses.
Where It's Happening
Infill activity is concentrated in Ottawa's inner-city and near-urban neighbourhoods, where mature lots are large enough to sever and land values justify the construction costs. Areas like Westboro, Hintonburg, Overbrook, Vanier, and parts of Gloucester have seen notable increases in severance applications and infill builds in recent years.
Even some traditionally quieter neighbourhoods, Carlington, Elmvale Acres, and sections of Barrhaven, are seeing their first skinny homes pop up as buyers and developers search for buildable land close to LRT stations and established amenities.
Why It's Accelerating
Several forces are driving Ottawa's infill boom. The city's Official Plan, updated in recent years, explicitly encourages gentle densification in established areas as a way to add housing supply without sprawl. Zoning reforms have made it easier to sever lots and build "missing middle" housing, a category that includes skinny homes, duplexes, and triplexes.
At the same time, the cost of detached homes in desirable Ottawa neighbourhoods has risen significantly, making it financially attractive for landowners to sever and sell, and for builders to construct new homes that can be priced competitively relative to older stock on the same street.
What It Means for Buyers
For buyers, infill homes offer a path into established neighbourhoods that might otherwise be out of reach. A new skinny home in Hintonburg or Westboro often comes in at a lower price point than a renovated older detached home on the same street, though buyers should factor in smaller lot sizes, limited yard space, and proximity to neighbours.
New builds also come with modern finishes, energy-efficient systems, and Tarion warranty coverage, which can offset some of the trade-offs.
What It Means for Sellers and Homeowners
For existing homeowners sitting on a wider-than-average lot, severance may be worth exploring. The process involves an application to the City of Ottawa's Committee of Adjustment, and approval is not guaranteed, setbacks, lot coverage rules, and neighbourhood character are all considered. Consulting a planner early in the process can save significant time and money.
Neighbours of proposed infill developments have the right to attend and comment at Committee of Adjustment hearings, and many do, particularly when proposed buildings feel out of scale with surrounding homes.
The Broader Picture
Love them or loathe them, skinny homes and lot severances are increasingly part of Ottawa's housing landscape. As the city works to add density and address affordability, infill development offers one practical answer: even if it changes the look and feel of the neighbourhoods it enters.
For anyone buying, selling, or simply living in Ottawa's established communities, understanding infill trends is becoming essential knowledge.
