About This Home

Twin Peaks modern vision parcel that will be subdivided into two separate lots, offering approximately 43 feet of combined frontage and sweeping city views. 421-423 Burnett Avenue is offered with plans for two dramatic side-by-side, separate and individual contemporary residences, each with its own legal ADU, thoughtfully designed to maximize scale, natural light, privacy, and indoor-outdoor living. The proposed designs feature two striking multi-level modern homes with expansive entertaining spaces, view terraces, luxurious primary suites, multiple bedrooms, and seamless connections to outdoor living areas. Plans also include separate legal ADUs, ideal for guest quarters, multigenerational living, a home office, or potential rental income. The two newly created lots measure approximately 2,989 and 2,896 square feet, both exceeding the City's 2,500-square-foot minimum lot size requirement. A unique setting for a significant architectural statement in one of San Francisco's most desirable hillside neighborhoods. Plans envision garage parking, landscaped terraces, roof deck elements, and sophisticated contemporary architectural detailing throughout. Ideally located moments from Noe Valley, the Castro, and the recreational trails of Twin Peaks, this is an exceptional opportunity for developers, investors, or end users to create two showcase residences with flexibility, scale, and panoramic outlooks. Buyer to investigate and verify the status of plans, permits, approvals, subdivision, and development potential to their satisfaction. Seller makes no representation regarding permit issuance or approval status. Buyer shall be responsible for all costs associated with obtaining building permits and completing construction.(these are renderings not photos)
