Local knowledge

Heritage by the lake, clay to the north.

Oakville grew from about 6,900 people in 1951 to more than 61,000 by 1971, after the Ford plant arrived and the town merged with Trafalgar Township and Bronte in 1962. Old Oakville, by the harbour, has homes from the early 1800s to the early 1900s. College Park went up mostly from the mid-1950s to the late 1980s, and Glen Abbey, River Oaks and West Oak Trails followed from the 1980s into the 2000s.

The ground changes as you head north. Much of north Oakville sits on Halton Till, a silt to clayey-silt till over shale bedrock that water barely moves through. Clay that stays wet pushes harder on foundation walls, which is a big part of why block foundations here bow and crack.

The Town is clear about permits. It lists underpinning foundation walls, excavating to increase basement headroom, and adding a below-grade entrance or walkout as work that needs a building permit, and recommends an architect, engineer or qualified designer for the drawings. We coordinate the engineering and the permit as part of the job.

Questions

Oakville questions, answered

Do I need a permit to lower my basement in Oakville?
Yes. The Town of Oakville's Building Services lists underpinning foundation walls and excavating to increase basement headroom as permit work, and recommends an architect, engineer or qualified designer for the drawings. We coordinate the engineer, the drawings and the permit before anything is dug.
My house is in a heritage district. What changes?
Some of the details. Oakville has four Heritage Conservation Districts: Old Oakville, First and Second Street, Trafalgar Road and Downtown Oakville. The Town's plan for Old Oakville recommends keeping original above-grade foundation walls, replacing extensively deteriorated foundations in kind and not parging over original foundations. We plan the repair around that and check with the Town's heritage staff first.
Can you build a walkout on a ravine lot?
Often, yes, but ravine and creek-side lots take more planning. Land near Oakville's creeks can fall under Conservation Halton's regulations as well as the Town's, so we check what applies to your lot before we design the opening, the shoring and the drainage.
