Welcome to 4580 Clay Street, a beautifully remodeled brick bungalow in the heart of Sunnyside. This 4-bedroom, 2-bath single-family home sits on a quiet, tree-lined block and blends classic 1925 character with thoughtful modern upgrades. Inside, the main level welcomes you into a bright, open living area with large windows throughout that bring in abundant natural light. The recently updated kitchen opens directly to the living and dining rooms, creating an easy layout for entertaining, with granite counters, stainless steel appliances, and plenty of cabinet space. Two bedrooms and a full bathroom complete this floor, including a primary bedroom large enough to accommodate a king-size bed-a rare find in a bungalow of this era. The finished basement significantly expands the home's functional living space with an additional bedroom with a walk-in closet, a secondary living room, a flexible bonus room, a 3/4 bath, and a laundry room with utility sink. A newly converted detached ADU adds exceptional versatility, perfect as a private home office, creative studio, or additional guest bedroom. Adjacent to the ADU is a two-car garage with ample room for parking and storage. Outside, the fully fenced backyard is framed by mature trees and features a spacious flagstone patio ideal for outdoor dining and entertaining. The home is set back from the street, allowing you to enjoy the low-maintenance, xeriscaped front yard from the covered front porch. Notable improvements made during the seller's ownership include: ADU conversion (2023), addition of central A/C (2021), kitchen remodel (2019), and new furnace & hot water heater (2018). Located just blocks from all the restaurants and shops along 44th Avenue, this home offers excellent walkability and convenient access to parks, downtown Denver, and I-70 for quick trips to the airport or the mountains. Don't miss your chance to own a move-in-ready home in one of the most desirable locations in Sunnyside!
