charging a 3/4" to a 1" water meter

I'm putting An addition on my house which has a bathroom and a laundry room. I currently have two bathrooms with showers and one tub. The inspector says that I have too many fixtures now for my supply line. I have 3/4 coming in from the street to the water meter and 3/4 branch lines there on. He wants me to put in a 1" meter. And increase the supply line. Can I increase the 3/4" coming from the street just before the meter and then continue on with the 1". Or do I have to dig up my whole front yard and run 1" all the way to the street turn off. He says I have 26 WFSU's. The cost of going to the street would be high so I hope I don't have to do that.
Thanks
Ron
