120 Hillendale Avenue is a thoughtfully updated central Kingston home that stands out for its extensive upgrades and completely legal secondary suite. With the major systems already addressed and a modern income-ready apartment in place, this is a rare opportunity to own a move-in-ready property that offers both comfort and flexibility. The primary residence blends character with modern improvements. Bright living spaces showcase original oak strip flooring on the main and upper levels. The layout includes a main-floor bedroom and full bathroom, plus two spacious upstairs bedrooms and a second full bath - a practical design that works well for families, guests, or home offices. A true highlight is the City-registered legal secondary suite, completed in 2020. This bright one-bedroom basement apartment features a modern kitchen, updated finishes, recessed lighting, and large windows that bring in natural light. Currently rented month-to-month at $1,500 inclusive, it provides excellent income potential or an ideal option for multigenerational living. Major upgrades mean the heavy lifting has already been done. The home features a newer metal roof with a 50-year warranty, updated furnace and air conditioning, all new windows installed in 2021, and a modern 200 amp electrical panel. A detailed list of improvements is available for interested buyers. Set on a quiet street in a convenient central location, the property offers easy access to downtown Kingston and the west-end shopping district, both about 10 minutes away. The neighbourhood is also home to École Élémentaire Publique Madeleine-De-Roybon. The oversized yard, abundant parking, and detached garage add practical outdoor space and flexibility. With its legal income suite, extensive upgrades, and highly convenient location, 120 Hillendale Avenue is a versatile, turnkey property suited to a wide range of buyers.
