Make Morning Sun Magical Again! A truly unique opportunity in one of Mill Valley's most desirable settings. 191 Morning Sun Avenue is a special property with an exceptionally large, street-to-street lot extending from Morning Sun Avenue to Lilac Lane, offering a rare combination of land, sunlight, privacy and upside. Currently configured as two units, the property presents an exciting opportunity to reimagine the site as a substantial primary residence with a separate ADU, guest space or income-producing unit with independent access from Lilac Lane. The existing home(s) provide a starting point, while the scale and configuration of the lot invite a much bigger vision. Imagine creating a generous view-oriented Mill Valley home with expansive indoor/outdoor living, a private yard and a separate space above or incorporated into the existing garage accessed from Lilac Lane. Whether the goal is a complete renovation, expansion or a thoughtful redevelopment of the property, there is significant potential for someone willing to bring the right imagination. Located in the Almonte neighborhood the property is close to Tamalpais High School, Mill Valley Middle School, local shopping and restaurants, with easy access to Highway 101 and all that Mill Valley and Southern Marin have to offer. This is an opportunity to acquire an unusually large parcel with multiple possibilities and create something truly special.
