Former firefighter here. The concern about balloon construction is real; it does allow for vertical spread of fire. With that method, the outside structural walls go up first, then the floor joists are added, then the interior walls are built - but since they don't go all the way to the exterior walls, there's a gap where fire can climb once it gets to the edge of the unit. If you've seen footage of the Grenfell Tower fire in the UK, it's very similar.

That said, the bigger concern I have in any building is whether it has 1) sprinklers and/or 2) multiple routes of egress. It's true that it's easier for firefighters to contain and extinguish a fire in a modern building with platform floors and drywall, but it's more important for people in residences / businesses to have the fire contained automatically or be able to get out before the firefighters arrive on scene.

I grew up in and love old houses but wholly agree with this argument.

A distinction that people fail to grasp is that in older housing there is much more variability in quality of construction. For example at one time in life I was part-owner and a resident of an 1890s three-flat in Chicago. It was lovely to look at....and built like crap. During that era thousands of those were thrown up across a city which was bursting at the seams with new immigrant population, and the builders had learned how to cheaply get the brick-and-stone look that felt to people like "solid housing". Underneath the exterior bricks though they cut every corner even by those pre-building-codes standards. Every time we had reason to open up a wall we'd be freshly amazed, in one way or another, that the place hadn't yet burned down or collapsed around us. And retrofitting what was needed always _cost_.

Old houses that were built for upper-class people often turn out to be built at least as well, overall, as most houses are today. Old houses that were built for middle-class or working-class people, do not. And naturally the latter vastly outnumbers the former. Then in either case there are certain modern safety features that were simply not invented yet let alone required.

I still love old houses, to be clear. It's just important to be realistic about the tradeoffs involved.
