Introducing the “Duneside Retreat”—a rare coastal opportunity offering exceptional development potential in a designated Opportunity Zone. Set on a versatile parcel, this property features a 2-bedroom, 1-bath main residence complemented by a 432 sq ft addition that functions like a Junior ADU. Complete with its own bathroom and a flexible layout, this is a fully permitted addition completed in 2001 that is ideal for multi-generational living, guest quarters, or potential income. With zoning that allows for a main residence plus up to three additional ADUs (each up to 1,200 sq ft, buyer to verify with SLO County), this property presents a compelling opportunity for developers, investors, or those seeking to create a multi-unit coastal compound. Located within an Opportunity Zone, buyers may benefit from significant tax advantages, including the potential to defer capital gains and eliminate taxes on future appreciation when held long term (buyer to consult tax professional). Beyond its development potential, Duneside Retreat offers immediate lifestyle appeal—ideal for owner-occupants, multi-generational living, or generating rental income through short- or long-term leasing. Its adaptable configuration makes it equally suited as a primary residence, vacation getaway, or income-producing asset. A truly unique offering combining location, flexibility, and long-term financial upside.
