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 project has received its land-use entitlement and is approved by the San Francisco planning Department. The approved plans 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)
Property is land value only, full reconstruction required.
The listing is for a development parcel sold with architectural plans rather than a completed home. The images provided are artistic renderings, and the property is valued based on land and subdivision potential.
The property offers a rare opportunity to subdivide a large parcel into two separate lots, each featuring a primary residence and a legal ADU, maximizing density and potential rental income or resale value.
Situated in the desirable Twin Peaks neighborhood, the site provides sweeping, unobstructed views of the San Francisco skyline, a premium feature that significantly enhances the appeal of the proposed luxury residences.
Ideally located moments from Noe Valley and the Castro, the property combines a tranquil hillside setting with convenient access to world-class dining, shopping, and recreational trails.
The sale is based on proposed plans and renderings; the buyer assumes all responsibility and costs for securing permits and subdivision approvals, which can be a lengthy and uncertain process in San Francisco.
With a $5 million entry price for land and plans alone, the project requires substantial additional investment for construction and development, posing a high financial barrier to entry.
