505 S Main Street presents a rare opportunity to acquire a high-visibility commercial asset positioned on a commanding hard corner in central Santa Ana. Boasting outstanding frontage on three separate streets including a major signalized intersection along South Main Street this premium corner lot spans approximately 0.90 acres (39,640 SF) and handles a heavy daily traffic volume exceeding 28,000 vehicles per day. The existing structure features a substantial ±18,650 square foot commercial footprint (comprising massive ground-floor showroom/warehouse space plus a functional second-story open workspace and private office layout). Supported by 44 gated, on-site parking spaces, the property provides immediate utility for an owner-user or retail repositioning. Beyond its current footprint, the property holds massive value-add potential. Designated under the city's favorable UN-20 (Urban Neighborhood) zoning framework, the site supports up to 20 dwelling units per acre and a 1.0 Floor Area Ratio (FAR). This highly versatile zoning enables a wide array of adaptive reuse strategies, including vertical mixed-use, live/work spaces, or an intensive residential infill redevelopment. Located just blocks from the booming Downtown core, the Civic Center, and direct transit lines, this asset is perfectly positioned to capture the immense public and private capital transforming the urban core of Santa Ana.
