In San Francisco, a TIC isn't a compromise. It's often the smartest way into the neighborhood.
More TICs trade in San Francisco than anywhere else in California. In whole swaths of the city — Noe Valley, Cole Valley, the Richmond, the Sunset, the Mission — a TIC is simply how you buy in. The city's older flats and Victorian-era buildings were frequently never converted to condos, and strict conversion limits keep many of them as TICs indefinitely. A modern SF TIC isn't more complicated than a condo. It's just less familiar, with a distinct set of rules around financing and conversion that reward knowing what you're doing.
A Tenancy in Common is co-ownership where two or more people each hold a percentage interest in a single building. Everyone's on the deed. No one owns a legally subdivided unit — instead, a separate contract called the TIC Agreement gives each owner the exclusive right to occupy a specific unit and sets the rules for how everything works.
In practice, your unit functions much like a condo: your own flat, your own front door, your own private space, while hallways, roof, foundation, and other shared areas are maintained jointly under the agreement — the same common-area concept a condo handles through an HOA. TICs are most common in San Francisco's 2- to 6-unit buildings and are the dominant ownership form for flats in the city's classic pre-war housing stock.
San Francisco TICs typically sell at a discount of roughly 15–20% relative to an equivalent condo in the same building or neighborhood. In SF's price tier, that spread often represents $150,000 to $250,000 or more. The discount is structural, and here's the actual chain of cause and effect — none of it a defect in the home:
You're not paying less because you're getting less. You're paying less because fewer people are standing next to you at the auction.
This single distinction separates the old scary TICs from today's safe ones. A blanket loan is one mortgage covering the entire building with every co-owner jointly on the hook. If one owner stops paying, the whole mortgage defaults and everyone's ownership is at risk. This is the structure behind nearly every TIC horror story — and in San Francisco today it's a red flag, not the norm.
A fractional loan is a separate mortgage secured only by your individual TIC interest. If another co-owner defaults on their fractional loan, your mortgage is unaffected. Fractional loans carry a rate premium of roughly 0.25%–0.75% above conventional rates, but they eliminate the cross-default risk that made blanket loans dangerous. Nearly all current SF TIC purchases use fractional financing. If a building is still on a blanket loan, treat it as a serious flag and ask about refinancing before you go further. On the larger required down payment: it's a quiet benefit, since default risk climbs sharply as down payments shrink, so it pre-screens your co-owners for financial stability.
For most buildings today, the honest answer is not right now. San Francisco suspended its annual condo conversion lottery in 2013 to address tenant-displacement concerns. It has been “expected to return in 2024, 2025, or 2026” in legal guidance for years — but as of mid-2026 it has not resumed, and the Expedited Conversion Program that temporarily replaced it has closed to new applications. Whether the lottery comes back is a political decision for the Board of Supervisors, and it has been anticipated and deferred repeatedly. There is ongoing pressure to reinstate it — but don't buy on that hope, for two reasons: the timing is genuinely unknowable, and when the lottery does return, eligibility is expected to be tighter, not looser. The maximum building size for conversion is slated to drop from six units to four, with stricter owner-occupancy and eviction rules, which would shut out larger buildings that can only convert in theory today.
For buildings of three or more units, conversion is effectively on hold until the lottery returns. That makes the two-unit bypass the primary live conversion pathway — and a major reason two-unit TICs command a premium.
The two-unit bypass lets a two-unit building convert if both units have been owner-occupied for at least one year by separate owners who each hold at least a 25% interest, with a clean eviction history. A few things can slam that door shut: a no-fault eviction (Ellis Act or owner move-in) or certain tenant buyouts in the building's recent history; evidence in city records of an unpermitted third or in-law unit; and note that at conversion, every tenant in occupancy must be offered a lifetime, rent-controlled lease. Converting an eligible TIC to condo status typically adds value (commonly cited in the 5–15% range) and unlocks conventional financing for the next buyer.
San Francisco layers city-specific requirements on top of standard TIC diligence. Confirm the loan structure is fractional, not blanket — every time. Read the full TIC Agreement with a TIC-experienced attorney; the Bay Area has a small circle of specialists, and Andy Sirkin's firm drafted many of the agreements you'll encounter. Pull the building's eviction and tenant-buyout history, since a no-fault eviction can disqualify it from future condo conversion. Verify soft-story seismic retrofit compliance through the SF Department of Building Inspection — many pre-1978 wood-frame buildings with a ground-floor garage must complete retrofits, and an open notice can mean significant capital cost. And understand your co-owners' financial stability and their intentions around conversion; you're entering a long-term relationship.
San Francisco's Rent Ordinance continues to apply to tenants within a TIC — converting a building to TIC ownership is not, by itself, an allowable reason to evict. During a condo conversion, every tenant in occupancy must be offered a lifetime, rent-controlled lease. Because a building's eviction history determines its future conversion eligibility, rent-control and eviction considerations sit at the center of any SF TIC analysis rather than off to the side. A building with a clean history is worth more — not for sentimental reasons, but because it keeps the condo-conversion door open.

SF TIC deals reward specialized knowledge. The difference between an agent who understands fractional financing and conversion eligibility and one who doesn't can be a six-figure swing in what you pay and what you can do with the property later. Measure the building on its financing, its agreement, and its real conversion path — everything else is noise.
I help buyers evaluate SF TICs — the financing, the agreement, and whether a building can realistically convert. If you've got a specific building in mind, I'll tell you straight whether it's a smart buy.
