In Renton, and most of the Seattle area, we have either a 3/4" or 5/8" meter at the street.
Threads from that will be 3/4", which we connect with something like a brass 3/4" mip x 1" insert fitting if you are using poly pipe.
If I run copper, I increase it as much as I need.
Depending on how many bathrooms, and the distance, I may use a 1-1/4" water service.
If it's really long, I may go 1-1/2", but it would need to be a very large lot for that, more like acreage.
