Wind mit single strap

About what year did they start using single straps?
How long have they been around for?

I inspected a house built in 1988 that had single straps

I have seen single wraps back to the fifties. That was one issue before the wind mit form, nobody could tell which houses would have been hardened. It really depends on the builder.

I have seen houses from the fifties that had rebar as the strap.
