The Boston triple decker should be the standard home of North America and nobody can tell me otherwise.

The issue with regard to single stair buildings are for things taller than 3 stories. IIRC in America 3 stories is the most common limit by far, and in Canada it's even worse with most regulations having 2 stories as the limit for a single stair complex.

The diagram illustrates that the longest aerial ladder firetruck available in North America is 137' / 41m, which should be able to reach about fourteen storeys high. A 'typical' aerial ladder is about 75' / 22m, which is about seven storeys.
