Multiplex Development in Whitby.

Turning one Whitby house into three or four self-contained homes is the strongest income move on the menu — and we carry it from feasibility to finished build.

Why Whitby

Whitby is built for this move.

Whitby’s family neighbourhoods and commuter demand make secondary units consistently easy to lease.

A conversion is won or lost on the unglamorous details — separations, exits, servicing, financing sequence. One team owning all of them is the difference between a stalled project and a rent roll.

The rules in Whitby: 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.

Whitby questions

Asked in Whitby.

Up to three units are as-of-right on most residential lots in Whitby, and a fourth is often achievable with additional approvals. Try the free "What can I build?" tool for an instant read.

A typical two-storey conversion runs roughly $680k–$980k all-in depending on scope — and units like these lease for about $2,100–$2,700/month each. Financed against the once-built value, the rents service the debt; your free report models it for your address.

Usually for the heavy phase, yes — but sequencing can sometimes keep part of the home livable. It’s one of the first practical questions we answer in your feasibility review.
