Polybutylene pipe

I have read that polybutylene pipes were not manufactured after 1994 in the U.S. Is it a reasonable assumption that a home that was built in 2009 in Ohio would not have polybutylene pipe from the meter to the house?

It would be unlikely to have PB in a 2009 house but possible since you can still buy PB2110 pipe in the US.
