Seattle and Vancouver aren't really comparable because even though they're both building dramatically more multi-unit buildings than in previous decades, what they're building isn't the same. For various reasons Seattle builds almost entirely purpose built rental apartments and nearly no condos. In Vancouver it's the reverse. Seattle now has a 5% vacancy rate whereas Vancouver has sub 1%, despite the fact that Vancouver has multi unit construction at all time highs (33k at the moment). It's a deeply complex problem and there's more to it than just building more. Clearly what Vancouver is building is not the right product to increase vacancy.
