Multiplex Development in Oshawa.
Turning one Oshawa 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.
Oshawa is built for this move.
Oshawa offers some of the strongest rent-to-cost math in the GTA — the same build simply pays back faster here.
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.

Asked in Oshawa.
Up to three units are as-of-right on most residential lots in Oshawa, 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.
