Opening home details…
Taking reference from the seaside communities of the East Coast, 227 Onyx Ave is unique for Balboa Island. Developed by Dahn Custom Homes and designed by celebrated architect, Richard Krantz, the home combines the elements of classical-style architecture with the inviting vernacular of a quaint clapboard beach house. This three bedroom and three and half bath plus den home is true indoor/outdoor living. The public rooms, including a large open kitchen with private patio and an exposed beamed living room, occupy the ground level. The second floor, accessed by the sunlight infused staircase or passenger elevator, contains the private bedrooms, master deck and den. The massive 950 SF third floor roof deck contains a covered outdoor dining and kitchen area and a partially covered sunbathing and entertaining space with views of the rooftops and ship masts beyond. Located on the corner of Balboa Ave. and Onyx Ave., this interior corner lot allows for quick access on and off the island and is steps away from the quaint shops and restaurants of Balboa Island’s Marine Ave and the beautiful bayside boardwalk.

ZIP averages use publicly displayable closed sales from our licensed MLS feed, matched to the same ZIP and exact property type. Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months. These averages are not adjusted for size, condition, or location within the ZIP, and are not an appraisal. Feed coverage may not include every sale. All available shows the available home and ZIP history, with mortgage rates over the same dates.
Mortgage benchmark: Freddie Mac Primary Mortgage Market Survey®. © Freddie Mac. Weekly national 30-year fixed rates, not APRs or a loan quote. Actual terms vary. Methodology changed in November 2022. The chart does not establish that interest-rate changes caused a home’s price changes.
Lines connect recorded asking and sale prices. They are visual guides, not estimates of the home’s value between those dates.
No earlier records were returned by our current sources. This does not mean the home has never sold.
