Richmond is undergoing rapid densification. Take a drive along the 3 Road corridor (Canada Line) and you will see a wall of cranes for construction of condos to the maximum height allowance (airport). The upzoning along/near  Canada Line in Richmond began far before the CoVs did along Cambie.

SF zoning along all major arterials in Richmond allows for condos/townhouses.

Richmond's very generous set-backs and massing, allows for huge 4-5000 sq foot homes to be built (and larger on agricultural land), and this has caused the ever escalating tear down of older sf housing stock.  Sadly though, these houses  often remain sold and empty, or under occupied. I suspect that in a few years (after developers work out a profit plan) Richmond will follow the lead of the CoV and allow more multi family options on all sf zoned lots.
