Marin County, California
Marin County occupies the peninsula north of the Golden Gate, with San Rafael and Novato as its urban centers and Point Reyes, Mount Tamalpais and the Marin Agricultural Land Trust holding most of the rest in permanent open space. It is among the most supply-constrained markets in the country, where ridgeline protection, agricultural easements, and a decades-old anti-growth planning tradition keep new entitlement concentrated in Highway 101 corridor infill.
