27 Acres Estate in Alpine is a Mediterranean-style event venue on Via Dieguenos with 17,000 square feet of combined indoor and outdoor event space. A 10,000-square-foot manicured lawn behind the 4,000-square-foot main mansion accommodates up to 250 standing guests under a canopy of permanent market lighting, a capacity matching the East County ranch-venue circuit anchored by Hazy Meadow Ranch on El Monte Road in Lakeside. The lower lawn, framed by an oak grove along a seasonal creek, serves as the primary ceremony site with a stepping-log aisle. A 1,000-square-foot covered patio outfitted with built-in speakers, a mounted television, and a full bar anchors the reception infrastructure, complementing the rehearsal-dinner circuit that includes Caffé Adesso on nearby Tavern Road. The venue operates on a bring-your-own-vendor model, requiring clients to source independent catering, floral, and rental providers rather than selecting from an in-house package.
