My now ex sister in law did exactly this for a tornado shelter. It was an extra 'lobe' of the basement foundation rectangle with no windows or structure above it. I seem to recall there was some extra work to make it water tight. Cost was only $10K or so (in 2010-ish), as are most greenfield things.
Granted it was for a new build house in the Red Deer area (Pine Lake was traumatic for her) but the City and Builder had no problem doing this as it was basically an extension of the basement. To make it a sound a little less crazy, in front of the kids and on blueprints submitted to the County it was labelled as "cold storage room". I want to say it was like 8x12" as it wasn't meant for prolonged habitation.
If you want some actual modern bomb shelter design info - checkout Singapore of all places as since 1996 it's been mandatory to have a "Civil Defense" shelter in all new places, including apartment style buildings. Kind of wacky to me given they live in 10-30 story apartment towers but then again I'm not the one who was bombed and occupied by an enemy force. Here is their 176 page technical design code requirements document: (its slow to load)

I can't wait to know what a post apocalyptic Republic of Silver will enact for laws! I'm not a dog person so I like my chances.
