Westboro sits within the City of Ottawa’s Kitchissippi ward, along the Ottawa River between the Byron Avenue linear park and Richmond Road, and has become one of the city’s most sought-after inner neighbourhoods – a status that changes the ADU math here more than almost anywhere else on this list.

Westboro's housing ranges from early-20th-century character homes near Richmond Road to mid-century construction further from the river, on a mix of standard rectangular lots and, on some blocks, lots with rear lane access – a legacy of how parts of the neighbourhood were originally platted. That variation means the right ADU type genuinely differs street to street here, unlike more uniform suburban subdivisions.
On the blocks that do have registered rear lane access, a laneway suite is often the strongest option: it keeps a tenant or family member's comings and goings off the main house's front yard entirely, which matters in a dense, walkable neighbourhood where street parking and foot traffic are already at a premium.
Westboro's rear lane access and lot layout vary block to block – the first step on any property is a site visit to measure your actual lot and confirm what your specific zoning allows.
Parts of Westboro carry heritage character overlays or are within a designated conservation district, which can add a design review step for a detached unit's exterior massing and materials, even where the underlying zoning permits it. We flag this during the feasibility review so it's built into the design timeline rather than discovered after drawings are already underway.
It depends on the block – some Westboro streets were laid out with rear service lanes and some were not. We check the City's lane registry for your specific address before designing toward a laneway suite.
Westboro's property values are among the highest of any neighbourhood in this list, which affects an ADU project's economics in two directions: construction costs don't come down because of it, but rental rates for a well-located, legal secondary suite here tend to run well above the citywide average, and a documented, permitted unit adds real, disclosed value on resale in a neighbourhood where buyers already expect a premium.
Westboro is the neighbourhood on this list where guessing from a Google Street View image is least reliable – lane access, lot layout, and heritage status can all change from one block to the next. A short site visit up front saves far more time than it costs.
