Legal Basement Apartments in Oakville

Serving Oakville and surrounding neighborhoods including Bronte, Glen Abbey, West Oak Trails, Joshua Creek, Iroquois Ridge, Old Oakville, River Oaks.

Typical Project Range

$75,000–$150,000+

ScaleBig Construction builds legal basement apartments across Oakville — from Bronte and Old Oakville through Glen Abbey, West Oak Trails, Joshua Creek, Iroquois Ridge, and River Oaks. Oakville's Additional Residential Unit framework allows accessory suites on most single-family lots, and we handle the engineering, building permit, ESA, and inspections in-house so the project stays predictable.

Oakville homes typically have higher ceiling heights and larger footprints than the GTA average, which means more rentable square footage and stronger long-term yield. A finished two-bedroom legal suite in Oakville often rents for $2,200+ — turning underused space into a real income property without changing how you live upstairs.
