First Time on Market! Rare two-parcel, fully vacant development opportunity in San Roque! Offering a unique opportunity for an experienced developer or investor to optimize two contiguous parcels totaling approximately 0.48 acres in the San Roque area of Santa Barbara. The fully vacant offering includes 685 N La Cumbre Road, a 3,287 SF structure on a 13,504 SF lot, and 3915 Harrold Avenue, a 448 SF one-bedroom cottage on a 7,330 SF lot. Held under common ownership for decades, the two properties provide a rare combination of scale, existing improvements, and flexibility. Both properties will require significant renovation or redevelopment and are not move-in ready. 685 N La Cumbre features a large existing structure with a 434 SF garage, basement space, and pool. The scale of the lot and existing structure give a buyer meaningful flexibility in how the site is ultimately configured. 3915 Harrold offers a 1920-era house with a detached garage and additional potential for future improvements, including possible ADU conversion, subject to significant renovation. Both parcels are zoned 8-R-1, providing additional residential flexibility subject to applicable County requirements and buyer due diligence. Land use survey available upon request. Together, the properties create a rare, near-half-acre assemblage with the opportunity to transform the existing improvements or pursue future residential development.

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.
