Tear down
TeardownExcellent
Property is land value only, full reconstruction required.
Built in 1918 and marketed explicitly as a 'development opportunity' and 'fixer upper' for a 'fresh start,' this property is over 100 years old with no evidence of significant renovation. The listing focuses on the 7,000 sq ft lot's potential for new custom housing or multifamily units rather than the existing 770 sq ft structure, which features dated wall heating and basic, aged finishes.
PROSSTRENGTHS & OPPORTUNITIES
- Exceptional Development Potential
The oversized 7,000 sq. ft. lot features rare dual frontage on both Commercial Avenue and 2nd Lane, providing superior flexibility for building layouts, ADUs, or a small multi-family development.
- Prime Transit-Oriented Location
Ideally situated within walking distance of the Grand Avenue commercial corridor and close to major biotech hubs, BART, and Caltrain, making it highly attractive for future residents and commuters.
- Versatile Investment Opportunity
The property offers multiple high-value exit strategies, including subdivision or separate-ownership options under local housing provisions, catering to a wide range of developer goals.
CONSRISKS & DEFICIENCIES
- Poor Structural Condition
The existing 1918 structure is a significant fixer-upper that likely requires a complete teardown or extensive capital expenditure to become habitable or marketable.
- Minimal Existing Utility
With only 770 sq. ft. of living space, the current residence offers very limited utility or rental income potential relative to the million-dollar-plus entry price.
