Welcome to this beautifully reimagined, updated and authentic 1928 Spanish duplex with a detached ADU/casita in highly sought-after Carthay Circle. Set back from a picturesque tree-lined street with a grassy front lawn, this Mills Act-designated historic property offers potential for significant annual property tax savings (buyer to verify). Enter to discover exceptional craftsmanship and timeless period details, including arched doorways, leaded and stained-glass windows, and gleaming hardwood floors. Both units, 6502 and the permitted 6500 ADU/casita, will be delivered vacant, offering an ideal opportunity for an owner-user or investor. Each residence features dramatic living rooms with vaulted ceilings, exposed wood beams, and gas-burning stucco fireplaces. The kitchens are bright, extensively remodeled, and equipped with Viking ranges, custom maple cabinetry, and French doors that open to private patios, one featuring a covered outdoor dining area for year-round entertaining. Updated bathrooms showcase separate showers and soaking tubs with charming honeycomb tile finishes. Design inspiration is taken from Maussane France and Biltmore Hotel in Montecito. The lush, private outdoor spaces are framed by mature hedges and fruit-bearing trees, including pineapple guava, fig, and Meyer lemon. Recent upgrades include a new silicone roof coating (2024), HVAC, electrical and power enhancements, firebox replacements, electrical trenching, and earthquake retrofitting. Newly designed hardscaping and landscaping were created by an award-winning Santa Barbara-based landscape architect. This prime central location is near parks, museums, and cafes, with convenient access to The Grove, Original Farmers Market, Beverly Center, and Rodeo Drive. The new Wilshire/La Cienega Metro D Line station, just blocks away, connects directly to DTLA, LAX, the Valley, and beyond. Fun fact: Commodore Sloat Drive was named after the U.S. Navy commodore who, in 1846, claimed California for the United States and served as the state's first military governor!
