Incorrect. Seattle buildings are mostly far below 1.0, with condos are townhouses being the exceptions. DPD has tons of information available online. Pay attention even sporadically (or religiously as some of us do) and this will be obvious.
I don't get why you're debating something so provable. Do you think readers can't see DPD too? Of are you presumptions so ingrained that you don't even bother to look first?
As for those neighborhoods out of the core, I don't get your question. Developers are mostly trying to meet their residents' demand, because if they don't then rents might end up significantly lower.
Edit: Let me make this easy. Here's the main portal to the LUIB, a twice-weekly bulletin. Choose any date (Thursdays are larger than Mondays) and view the whole issue's list by hitting "print." Every single issue you'll find a lot of projects in various stages of land use permitting. As I said, the exceptions will be developers that focus on condos (Bosa, Onni, Clise, Continental mostly), with the large majority being rentals (not counting townhouses), nearly all with a lot fewer spaces than units, even if there's also retail etc.

A caveat is that the description is generally the original, often from pre-bust, and many jobs that are later revived (for example Potala Tower, 815 Pine, Insignia and so on) change the unit/space mix, always with more units per space because that whole market dynamic is very different in this boom vs. the last one. Potala Tower for example is doing 200 spaces for something like 347 units and 147 hotel rooms if I recall, making it way easier to fit into 1/3 acre.
