About this home

This unique property features two separate remodeled homes (one with high end finishes) situated on one expansive lot, offering excellent flexibility for multi-generational living, rental income, or future development potential. Both homes enjoy a prime location within walking distance to Castro Valley Boulevard’s shopping, dining, and everyday conveniences. Commuters will appreciate the easy access to major freeways, making travel throughout the Bay Area simple and efficient. The large lot provides abundant outdoor space for gardening, entertaining, or expansion, while also presenting exciting possibilities for investors or builders seeking to maximize value. Whether you’re looking for a live-in one, rent-the-other setup, extended family housing, or a property with long-term upside, this Castro Valley gem checks all the boxes. Don’t miss your chance to own two homes on one lot in a convenient and desirable location with tremendous further development potential! Check with Alameda County to confirm that the lot supports up to 8 condos or townhomes or if you could do a 5 way lot split and build 3 additional detached separate homes. New central heat and A/C in main house. Both houses have new water heaters.

This property features two homes on one lot, both of which have undergone significant renovations. The main house appears to be extensively renovated with high-end finishes, including a modern kitchen with premium appliances (Bertazzoni), recessed lighting, contemporary flooring, and new central heat and A/C. The second unit is also remodeled with a modern kitchen (stainless steel appliances, white shaker cabinets, subway tile backsplash) and updated flooring. However, the second unit's bathroom, while functional, features an older-style tub/shower combo and a pedestal sink, which are not as modern or high-end as the main house. Additionally, the second unit appears to have a wall heater rather than central HVAC. While the main house is excellent, the second unit's slightly less updated bathroom and heating system, despite being remodeled and move-in ready, pull the overall property score to 'Good' rather than 'Excellent'. Both homes have new water heaters, indicating recent updates to major systems.
Pros & Cons

Pros

Dual Income/Multi-Generational Living: The property features two separate remodeled homes on one expansive lot, providing excellent flexibility for multi-generational living arrangements or significant rental income potential.
Significant Development Potential: The large lot offers tremendous long-term upside, with explicit mention of potential for up to 8 condos/townhomes or a 5-way lot split for 3 additional detached homes, subject to county approval.
Prime Location & Accessibility: Situated within walking distance to Castro Valley Boulevard's shopping, dining, and conveniences, and offers easy access to major freeways for efficient Bay Area commuting.
Extensive Lot Size: The substantial 20,181 sqft lot provides abundant outdoor space for gardening, entertaining, or future expansion, enhancing its appeal and value.
Recent Major Upgrades: The main house benefits from new central heat and A/C, and both homes have new water heaters, reducing immediate capital expenditures for essential systems.

Cons

Unconfirmed Development Potential: The stated development potential for condos/townhomes or lot splits requires verification with Alameda County, indicating it's not pre-approved and necessitates significant due diligence, time, and investment for permits and studies.
Age of Original Structures: Built in 1925, despite remodels, the original structures may have underlying issues or require ongoing maintenance typical of older properties that could lead to unexpected costs.
Increased Maintenance Burden: Owning and maintaining two separate homes, even if remodeled, generally entails higher ongoing maintenance costs, utility expenses, and management effort compared to a single-family residence.
