Many people are surprised to find out I live in Larkspur when they thought I lived in Greenbrae but I have a Kentfield zip code. Did I confuse you?
Our little cities in Marin County are so close together, I think it is confusing to everyone. So how does this whole city/town/county thing work in Marin?
Part of Greenbrae is unincorporated, meaning it is not part of a city or town with its own government. Another part of Greenbrae is incorporated into Larkspur. Need a building permit and you live in that half of Greenbrae? You go to the City of Larkspur. Live in the unincorporated are of Greenbrae? Permits and other services fall under the domain of Marin County.
The zip code for Greenbrae is 94904. 94904 is also the Kentfield zip code. Like Greenbrae, Kentfield is also unincorporated.
The school district for Greenbrae is not the Corte Madera -Larkspur School District, it is in the Kentfield School District. Go figure.
Got it?
