This charming Spanish Colonial Revival home, located at 523 South Illinois Street, offers a rare blend of historic integrity and sophisticated modern luxury. Situated within the Anaheim Colony Historic District, this 1,196-square-foot residence features three spacious bedrooms and two elegantly remodeled bathrooms. One of the most significant financial advantages of this property is its active Mills Act contract, which allows the new owner to inherit an incredibly low annual property tax bill of approximately $2,959, with no supplemental tax reassessment upon sale. The home is nestled on a unique block of twenty cohesive, character-rich homes built between 1923 and 1928, providing a streetscape and neighborhood feel unlike any other in Downtown Anaheim. While the 1928 architecture remains preserved, the interior has been meticulously updated for contemporary living. The floorplan is open with formal living and dining rooms leading seamlessly into the recently remodeled kitchen. The layout boasts high ceilings with recessed lighting, designer wallpaper accent walls, and high-end light fixtures throughout. The true primary suite serves as a private sanctuary, featuring a walk-in closet and a spa-like bathroom complete with dual sinks, custom tile work, and three shower heads. Other value add improvements are updated plumbing and electrical, central air and heat and more! Beyond the stunning interior, the property offers exceptional outdoor and functional features, including an incredible viewing deck perfect for watching the nightly Disneyland fireworks. The three-car detached garage provides ample storage and presents a prime opportunity for conversion into an ADU (Accessory Dwelling Unit). Located just blocks from the vibrant Anaheim Packing District and downtown's diverse shopping and events, this home places you at the heart of the city's most energetic cultural hub.
