Located just minutes from downtown Castle Rock, 416 Gilbert St presents a rare opportunity to own a move-in ready home with a partially finished ADU already set up for customization and future value. The main residence features a completed cosmetic remodel with updated kitchen and bathroom finishes, new flooring, paint, and modern fixtures throughout. Clean, functional, and ready for immediate occupancy. The detached ADU is where this property separates itself. Key infrastructure is already in place, including permitted water and sewer connections, plumbing rough-ins for a kitchen and 3/4 bathroom, and installed mini-split heating and cooling system. The seller intentionally left the interior unfinished, giving the next owner the ability to design and finish the space to their specific use case. Whether you're planning for rental income, multigenerational living, a private office/studio, house hack or future resale upside, the heavy lifting has already been completed. Additional features include a detached garage, 2 off-street parking spots behind the ADU, and a front driveway. The property is positioned close to shops, restaurants, and the Castle Rock riverwalk, offering both convenience and long-term desirability. Opportunities with ADU infrastructure already in place in this location are limited. This is a property with both immediate livability and built-in upside. Showings Start Saturday March 21st. Feel free to contact listing agent with any questions.
