Co-development is the answer to a very specific problem: your lot is worth more as a multiplex site than as a house, but you have neither the capital nor the appetite to run a construction project. In a co-development, you contribute the land, a builder contributes money and execution, and the proceeds are split under a structure you agree to before anyone touches a shovel.
The common shape: the land owner contributes the property at an agreed value, the builder funds construction and manages the project, and each party's share of the completed homes or sale proceeds reflects their contribution. Sometimes the owner keeps one of the new units and takes less cash. Sometimes the owner stays in the existing house until permits are ready. The structure is negotiable; what is not negotiable is writing all of it down with lawyers before work begins.
Selling to a builder hands them the development margin along with the risk. Co-developing keeps part of that margin for you, in exchange for time and shared exposure. For long-tenured owners with big equity and no mortgage pressure, trading a year or two of patience for a meaningfully larger outcome, or a new unit on the lot where they raised their family, is often the right deal. The retiree who ends up living in one new unit while renting or selling the others is the textbook case.
Construction cost overruns, market movement between agreement and completion, financing conditions, and partner quality. The last one towers over the others. A co-development is a multi-year relationship, and the builder's track record, financial standing, and how they behave when something goes wrong matter more than a point or two on the split. We introduce clients only to builders we would partner with ourselves, and we say no to structures where the owner carries risk they cannot see.
The best co-development lots share traits: eligible for three or more units, serviced without heroic upgrades, in locations where the finished homes sell strongly, and owned with enough equity that the owner can be patient. If that sounds like your property, the next step is a feasibility conversation, not a commitment. Start with our Port Moody multiplex guide or bring us your address.
The property itself, at a value agreed upfront. The builder typically funds construction and manages the project, and proceeds are split to reflect both contributions.
Often, yes, until permits are in place and construction begins. Some structures also let the owner take one of the finished units instead of a larger cash share.
Independent legal advice, an agreed land value, a defined split, clarity on cost overruns, and a builder whose track record you have verified. If any of those is missing, do not proceed.
