Why Invest in a Duplex?

  • Built-in Utility & Income
    Live in one unit and lease the other—optimizing housing costs through rental income, especially useful in SF’s high-priced environment.

  • Appreciation Stability
    Two-unit buildings tend to maintain their value even when markets soften. From mid-2022 data, median duplex sales hovered at $1.9M with strong buyer interest across neighborhoods like Noe Valley, the Mission, and the Sunset. Nearly 40% sold above asking, some by over 20%, and 16% sold all-cash.

  • Multi-Generational Living Made Practical
    Highly suited for extended families—parents upstairs, children downstairs—this model supports shared resources and built-in assistance. One Business Insider story highlights two sisters buying a duplex near Golden Gate Park; they split mortgage costs, utilities, and enjoy built-in childcare and mutual support.

Duplex Realities in San Francisco

  • Stringent Rent Control Laws
    Duplexes fall under SF rent control if built before 1980. This means long-term tenants may stay indefinitely, limiting rental strategies and flexibility.

  • Disproportionate Valuation
    Converting a single-family home into two units can reduce market value; one homeowner reported losing about $1M in perceived value after splitting their house.

  • Regulatory and Financing Barriers
    Permitting is slow—though improving, SF’s average approval timeline once stretched past 1,000 days for certain housing types. Financing duplexes can be more complex than for single-family homes, especially where TIC (Tenancy In Common) or condo-conversion statuses apply.

  • High Demand, Strong Buyer Profiles
    Buyers—TIC partners, owner-occupiers seeking rental income, pure investors—seek large, vacant duplex units with near-equal sizes. The duplex segment remains resilient in SF’s competitive landscape.
