8 Avocet Cout is in Novato, so it goes to Novato Unified School District. Since it is a new construction, so it has not shown up on NUSD's list of addresses on which schools it belongs to.
However, with NUSD's neighborhood school concept, I checked on the neighborhood schools are for homes on two close-by streets (Maybeck and San Pablo). Homes on those two streets go to Hamilton for elementary school, Hamilton (an 1-8 school) and San Jose (7-9) for middle school and then onto Novato High as high school.
Hope this is helpful.
