Overview

This two-story duplex features two identical, mirror-image layouts, creating separate living spaces with the privacy and feel of a single-family home. Each unit includes three bedrooms, 1.5 bathrooms, a living room, dining room, eat-in kitchen, and a back porch. The main level also offers laundry, and the design places living areas on the first floor and sleeping space on the upper level for clearer separation.

The property includes basement access with both interior and exterior entry, which can be helpful for storage or a workshop setup. The home is located on Ottawa’s historic east side, within walking distance of the downtown shopping and dining areas, as well as a public east side park and the Illinois and Fox Rivers.

For buyers, this configuration can support owner-occupancy with a second unit for rental income, or an investment approach for tenants seeking a multi-unit residence with single-family-style separation. The identical layouts also simplify planning for maintenance and leasing, while the basement access adds flexibility for day-to-day use.
