Its important to remember that there are no absolute certainties; not all old houses are well built; not all late 20th century houses are ####. But, generally speaking there is a definite trend that does hold true.
The main benefit of old homes is their breathability. They tend not to get moldy as moisture can escape easily. The houses that are sealed but not ventilated are the worst, especially when moisture finds its way into the wall cavities.
That said, renovation of pre 1990 homes is expensive and hazardous as there are a lot of building materials in those homes that are harmful to demolish, and special measures need to be taken when working around them.

I’m curious — what do you attribute that to, especially as it relates to Calgary? Different materials? Different building designs/codes/techniques? Better (or worse) workmanship? All of the above?
