What can I build on my lot is the question we hear more than any other since BC rewrote its zoning rules. The honest answer is: more than you could three years ago, and probably more than you think. Here is the menu, in plain language, and how to think about choosing from it.
A secondary suite is the entry point: a self-contained unit inside the existing house. Lowest cost, lowest disruption, and now permitted almost everywhere in BC.
A garden suite or laneway house is a detached small home in the yard. It keeps the main house intact, generates rent or houses family, and suits owners who want income without a full rebuild.
A duplex replaces or converts the house into two full-size homes. It is the simplest full redevelopment, and in many markets each half sells or rents strongly because family-sized attached homes are scarce.
A triplex or fourplex is where SSMUH changed the game: three to four homes on a standard lot, outright permitted in most Metro Vancouver municipalities. This is the classic missing-middle project and usually the strongest land-value play.
Six units near transit is the ceiling on qualifying lots close to frequent transit service, where provincial rules push density higher.
Start from your goal, not the building. Income while you stay put points at a suite or laneway. Maximizing what you walk away with points at building or selling to someone who will. Housing multiple generations points at a duplex or multiplex with the right unit mix. And your capital position matters: suites cost a renovation, multiplexes cost a construction project, and the financing structures are different animals.
First, what does your zoning and lot actually permit: size, frontage, transit proximity, and municipal specifics all move the number. Second, what does servicing look like: water, sewer, and access constraints can add real cost. Third, does the math work: land value plus construction cost against end value, with a margin that survives surprises. We run this feasibility for homeowners before anyone pays for drawings, because the cheapest mistake is the one you catch on paper. Our SSMUH guide covers the legislation behind all of this.
Detached accessory homes are permitted in most Metro Vancouver municipalities now, subject to lot size, access, and servicing specifics. A quick lot review confirms what applies to your address.
It depends on lot economics and your capital. Fourplexes usually create more total value on eligible lots, while duplexes cost less to build and sell into a deep family market. The feasibility math, not a rule of thumb, should decide.
Zoning and unit-count confirmation, a servicing check, and a financial model comparing build cost against end value under a few scenarios. It is the homework that should precede any architect or listing decision.
