The point is, hot-dipped galvanized nails will do the job for 99% of the houses out there. I'd only specify stainless roofing nails if I lived at or close to the ocean. Hot-dipped galvanized nails can last well over 100 years in non-oceanic climates.he point is, hot-dipped galvanized nails will do the job for 99% of the houses out there.

Costs more to build out. As you said, there are all kinds of other factors, but the same square footage in two stories will cost less to build than in one. Most homes with traditional foundations can sustain a second floor addition without additional support.
However, if you are trying to build a 2-3,000 square foot restaurant with a brand new buildout/kitchen, then yes, the gap between the start up cost of a food truck vs. a restaurant is far wider. A new build out will likely cost $400-$500,000 all in. But there in lies the rub.
