Welcome to 873 9th Street! This lovely home has been transformed from top to bottom, blending thoughtful design with modern constructions and systems. The basement was rebuilt from the ground up, converting an unfinished space into a fully equipped 2 bedroom, 1 bath apartment with its own entryway, laundry and storage - ideal for guests, rental income or multi generational living. The work included a new slab, drainage, and waterproofing system, egress windows, and major structural upgrades. The main level was also fully reimagined with an open, functional layout featuring an expanded kitchen and dedicated office. Nearly everything is new as of 2021, including the framing and insulation to the solid white oak floors, windows, and mechanical systems. The fireplace and stairs are original, preserving a touch of character to the home. The upper level has been refreshed with refinished floors, new windows, added HVAC, and improved layout for better flexibility and use of space. The entire house is electric. Carport with storage shed; Tesla charger plus a 240v plug so you can charge any electric vehicle. The views from the expanded back deck are incredible. Newer walkways and flower beds have been added as well. All renovations were fully permitted and city inspected, offering piece of mind and move in ready convenience.
