The main home features original Douglas Fir floors, 6 panel doors, Craftsman casework, 3 beds, 2 3/4 baths, a covered front porch on tapered brick piers, and a skylit finished attic with charming flex space. Tucked below is a fully finished walk-out garden level apartment, a true second unit with its own private, entrance on the east side and separately metered is ready for a tenant, guests, or a standalone private suite. Out back, a detached 3-car garage (rare on this end of Mapleton Hill) is topped by a 612 SF studio currently with a half bath, convertible to full, with light and bright, living space under current Boulder zoning for a third income stream. RMX-1 zoning supports single-family, duplex, or triplex use across the property's two structures.
