Secondary Suites & ADUs in Whitby.
Basement, garden and laneway suites are the fastest way to turn a Whitby property into an income property — designed, permitted and built by one accountable team.
Whitby is built for this move.
Whitby’s family neighbourhoods and commuter demand make secondary units consistently easy to lease.
For suites, that means one thing: the permission question is mostly settled. What decides your project is design, servicing and execution — and that’s exactly what we own.

Asked in Whitby.
As honest ballparks: a basement conversion typically runs $90k–$145k all-in at standard size and finish, and a new garden suite roughly $215k–$280k. Your free report prices your actual project for your Whitby lot.
Under Ontario’s Bill 23, up to three units are permitted as-of-right on most residential lots in Whitby, and Durham’s growth corridors keep rental demand strong. Individual designs still need permits and can be shaped by lot specifics — which is what the free report checks.
Typically 2–4 months for design and permits, then 4–8 months of construction depending on the suite type. We set a realistic timeline for your project up front — and one team carries it to keys.
