Are single storey buildings (i.e. bungalows) cheaper to fix than multistorey buildings if they have major defects? For example structural problems.

Background. We're looking at buying our first house. We live in Melbourne, Australia. Laws regarding building construction standards are poorly enforced here and as a result there are many issues with new and recent build homes. Single storey buildings are still common here - of the market sector we're looking in, roughly 50% are single storey. If I brought a home and it later turned out to have a major defect / structural problem, would it probably be cheaper to fix for a single storey home compared to a multistorey? Do I therefore minimise my risk by buying a single storey?
