is there a lower limit on the size of a nuclear bomb?

Question

And if so, what factors determine it?

I know that the scale of the explosion is an insane amount larger than the teeny molecules causing it, but I’m wondering if there could ever be nuclear explosions small enough to take out a single house or block, rather than a whole city from high above.

Science wise, yea but tactical application wise, no because the US (of course the US) made the Davy Crockett, which was basically a nuke launcher slightly larger than a bazooka to be used at company level.
