Abundant housing, abundant transit, & abundant bike lanes in our cities occupies a lot of my thinking. I'm sure other pieces of my personality will peek through over time.

What would you estimate the size of this 3 bedroom unit is?

The U.S. is functionally now a pariah state and must be treated as such until the cancer rotting out the heart of the White House is cut out.

Where'd you find these?

Yeah there doesn't seem to be a hard cap. So the bigger lots have some advantages to get more units

I believe it is 10' front, 10' rear, and 5' side. No rear setback if an alley exists

Yes, generally 50x100. In parts of the city where there are larger single family lots they can range from 60' to 70' wide & about 130' deep.

Yes, per square foot of lot area. The typical generalization is Seattle single family lots are 5000 sf. Hence the 8 and 10 in the OP

To be a little more specific the number of units is tied to a unit/sf. But yes, no catch.

Also, you mentioned "enclosed" station means both underground & covered. So would the Canada Line example you cited, if built in Seattle, would also have to be mostly sprinklered (even though the tracks & platform are mostly open to the air)?

Under Seattle Fire Code (and NFPA 130 to some extent), above ground stations of the Canada line would be illegal: just one mean of egress (a fixed stair beside an escalator), 100% of egress capacity provided via public stairs with no emergency exits.

I've reread this thread for something I'm writing & I'm trying to understand the impact of this one. This seems to specifically impact construction efficiency. Is the hold up here instead of having bores race to the middle & go 2500 ft at a time. They are forced to twin bore & stop every 800 ft?

You don't use elevators during a fire & they've trained to move a stretcher up & down stairs. A larger elevator makes their job easier in the rare occasions it is needed (carrying stretcher down stairs is more arduous but it is doable) but it comes at a high cost to the general public

Many single family homes are 2 or 3 stories, with stairs that are generally narrower in width and steeper in rise than stairs in apartment buildings. So again, they've trained for this and climbing apartment building stairs is likely slightly easier in terms of width & steepness.

If a medical situation that requires a flat stretcher (extremely rare) happens in an existing multistory building with no elevator, then emergency responders use the stairs to carry the stretcher. They are trained to do this. Two responders at each end, carry it down.
