Property Description
Rare corner lot compound opportunity on over a third of an acre (14,690 sq. ft. parcel) in an ideal location for developers, investors, or owner-occupants. Sold strictly as-is near Hayward BART with newer roofs on both detached structures. This property consists of two detached single-family homes sitting on one single legal lot: the primary 3/1 residence at 21492 Montgomery Ave (1,215 sq. ft.) and the secondary 2/1 detached home at 938 Grove Way (770 sq. ft.). Unmatched opportunity in highly desirable unincorporated Alameda County in Cherryland. Local zoning and an expansive lot footprint provide a solid canvas for qualified buyers to explore potential development pathways, including a traditional minor subdivision / parcel map split to create two independent legal lots (subject to County approval). Alternatively, buyers can evaluate progressive California ADU legislation to explore building up to two additional detached ADUs for long-term density expansion. Transit-oriented location under half a mile to Hayward BART triggers state exemptions, eliminating standard off-street parking replacement mandates for future footprints. Regarding tenancy and possession status, both detached homes are occupied by cooperative tenants on month-to-month leases. Please note that move-out discussions apply strictly to the main house at 21492 Montgomery Ave; the small house at 938 Grove Way is sold as an active ongoing rental. Having previously held informal move-out discussions with the main house tenant, the seller is prepared to re-engage regarding potential move-out terms upon offer submission and will consider providing a 90-day post-closing rent-bank credit at closing. This potential path to vacant possession opens the door for both owner-occupants looking for a primary residence and savvy investors seeking flexible project timelines. Interested buyers are advised to include main house move-out terms as a condition of their offer to initiate these formal discussions. Both detached residences feature functional layouts with wood flooring, tile kitchen flooring, durable granite countertops, open-concept living and dining areas, indoor washer and dryer hookups, and separate gas and electric meters (only water shared). Offers reviewed as received.
