30 Miller Avenue presents a rare opportunity to acquire an immaculate retail and office property in the heart of downtown Mill Valley. The 3,431-square-foot building features a prominent retail storefront along Miller Avenue with four private office suites in the rear, providing a diversified, stable income stream. The retail space is leased to an established tenant in good standing, with approximately three years remaining on the current term plus a five-year renewal option. The property has been exceptionally well maintained and benefits from rooftop solar, seven newer mini-split HVAC systems, a new roof section and replaced awnings. Its prime location, strong tenancy, and pride-of-ownership condition make 30 Miller Avenue an attractive investment in one of Marin County's most desirable commercial districts.
