About This Home

As of May 2022

Rare opportunity to own a piece of iconic Mill Valley! Turn of the century brown shingle in a sunny, peaceful setting. Set in a clearing amidst the redwoods on a level and gently downsloping lot, the property enjoys bucolic views of Blithedale Ridge. Per the seller, whose family has owned the property since the 1960's, the house was built in 1909 on one of the first lots on Middle Ridge to be developed. Potential, potential, potential! Enjoy/improve the existing three bedroom, two bath home plus detached office (with ADU possibilities) or build your dream estate or getaway. Close to Old Railroad Grade and many of the most striking trails on Mount Tam. 1.7 miles to downtown Mill Valley and its many amenities.
