Located in the heart of downtown Ukiah, the historic Marks Building at 102 S State Street stands as one of the city's most iconic commercial properties. Built in 1889, this beautifully preserved two-story brick structure offers more than 11,000 square feet of mixed-use space on a prominent corner lot with high visibility and steady foot traffic along one of Ukiah's busiest streets. The ground floor is home to an established business that brings vibrancy and consistent activity to the building. Upstairs, the second floor is thoughtfully configured with approximately sixteen professional office suites, offering flexibility for a variety of tenants or future reconfiguration to meet evolving needs. With its classic architectural details, strong street presence, and nearly 150 feet of frontage along State Street, the Marks Building blends timeless character with modern functionality. The property sits on a 0.13-acre lot zoned C2 - Mixed Use, allowing for retail, restaurant, or office uses, and presents a strong opportunity for both investors and owner-occupants seeking an income-producing downtown asset.
