118 Emerald Situated on the highly sought-after “Quiet End” of Balboa Island, 118 Emerald Avenue represents a truly rare opportunity to own in one of the island’s most desirable and tightly held locations—less than one block from the harbor and south bayfront. This is one the last remaining original beach cottage on the 100 Block of Emerald, offering a unique blend of classic coastal charm, immediate usability, and long-term upside potential. Properties of this caliber and positioning seldom come to market. Currently configured as a duplex with two active short-term rental permits, the property provides exceptional flexibility for both personal enjoyment and income generation. The front unit is a charming single-story 2-bedroom, 1-bath coastal cottage, featuring a spacious front patio framed by a white picket fence—ideal for relaxing, entertaining, and enjoying the quintessential Balboa Island lifestyle. The rear unit offers a 3-bedroom, 2-bath split-level layout, complemented by a private 2-car garage, vaulted spatial flow, and functional separation for guests, tenants, or extended family. Both units are move-in ready, allowing for immediate occupancy or rental income. Alternatively, this property presents a compelling opportunity to design and build a custom luxury residence in an A+ location with enduring value.
