You walk into a converted warehouse loft on Rausch Street. Fourteen-foot ceilings, exposed brick, steel-frame windows the size of garage doors. The listing agent mentions the price per square foot is lower than almost anywhere else in the city. It feels like a find.
Then your loan officer calls back with questions about the building's unit count, its owner-occupancy percentage, and whether it has gone through a Fannie Mae Condo Project Manager review. The charm that sold you on the space has nothing to do with what determines whether you can finance it. In SoMa right now, that gap between the romance of the building and the mechanics of the loan has widened, and it widened specifically this August.
The Ordinance That Built SoMa's Loft Inventory
SoMa's loft stock exists because of a policy that failed at its stated goal and succeeded at an unintended one. In 1988, San Francisco passed an ordinance easing loft conversion and live/work construction in the Mission, Potrero Hill, and South of Market, aiming to give artists affordable studio-residences. In 1993, only 38 live/work units were built under it. By 1998, the Planning Department had nearly 2,800 more pending or approved, according to SF Heritage's history of the neighborhood. The pace outran the purpose. A city analysis in the early 2000s found the program had largely failed to put artists in those units at all, and by 2002 the ordinance was repealed.
By then the building stock existed and wasn't going anywhere. A San Francisco Board of Supervisors accounting from that era found the large majority of the roughly 1,700 units built under the ordinance landed in SoMa, with the next largest share in the Mission at a fraction of that. That is why SoMa, more than any other San Francisco neighborhood, is a live/work and loft-conversion market first and a traditional condo market second.
Some of the resulting buildings have real architectural pedigree. The Mullen Buildings at 52 and 60 Rausch Street and 73 Sumner Street were built in the 1920s and converted to housing in 2002. One Ecker Place began as an early-1900s warehouse before a 2008 conversion into 51 residences near Yerba Buena. H2O Lofts at 1247 Harrison Street dates to 2004. Stanley Saitowitz designed 855 Folsom's steel-and-glass loft interiors. These are not generic condo comps. Each one carries a different unit count, a different age of systems, and, as of this year, a different financing path.
What "Live/Work" Still Means on Paper
Most SoMa lofts function exactly like ordinary condos day to day. But a technical requirement from the original zoning, that at least one occupant hold a business license tied to the unit's live/work designation, still sits on the books for buildings that trace back to that era, even though enforcement is effectively nonexistent. Many of these lots were later rezoned to Urban Mixed Use in the 2000s, which cleared the way for any residential use, not just artists. But title history and 3R reports on older conversions can still carry the original live/work classification, which matters when a lender or an appraiser is trying to confirm what, legally, they are financing.
This is not a reason to avoid a loft. It is a reason to pull the building's permit history and zoning classification before you write an offer, not after your lender flags it during underwriting.
A Discount That Shows Up in the Comps
SoMa's pricing already reflects its loft-heavy, condo-second character, and the neighborhood is not one price point. A January 2026 snapshot put the broader SoMa condo and loft market at a median sale price around $910,000 with roughly 60 days on market, while the Central South of Market subarea specifically showed a median closer to $669,000 with faster turnover near 42 days. That spread inside one neighborhood name is the first sign that unit type and building vintage matter more here than almost anywhere else in the city.
Tenancy in common ownership, common in some of SoMa's smaller converted buildings, trades at its own separate discount. Across San Francisco in 2026, TICs have typically priced 10 to 20 percent below comparable condos. Citywide MLS data covering closings from mid-July 2025 through mid-July 2026 recorded 312 TIC closings with a median premium of roughly $101,000 over list, a discount of about $95,000 against the citywide condo median for often-larger space. Recent SoMa-specific loft sales bear this out at the address level: 60 Rausch Street closed around $1.02 million in August 2025, and 355 Bryant Street closed near $1.30 million the same month, both consistent with the mid-market range typical of SoMa's converted-warehouse inventory rather than its glass-tower comps.
| SoMa Metric | Value | Window |
|---|---|---|
| SoMa median sale price (all condo/loft types) | ~$910,000 | January 2026 |
| Central SoMa subarea median | ~$669,000 | January 2026 |
| Typical TIC discount vs. comparable condo | 10% to 20% | 2026 |
| Citywide TIC median premium over list | ~$101,000 | closings, July 2025 to July 2026 |
None of these numbers tell you whether a specific loft is a good deal. They tell you that in SoMa, the price gap between one building and the next is doing real work, and increasingly that work is about financing eligibility, not finish quality.
The Rule That Changed This August
Here is the development that makes this worth writing down now instead of filing under general SoMa trivia. As of August 3, 2026, Fannie Mae eliminated its Limited Review and Freddie Mac eliminated its Streamlined Review for new condo loan applications. Those two pathways had let many established, smaller condominium projects skip a full underwriting review of the building itself. Now, most projects need to qualify through a Full Review or a Waiver and Exempt From Review pathway instead.
The same change includes a counterweight that matters specifically for SoMa's older, smaller loft conversions. Fannie Mae and Freddie Mac expanded the size threshold for streamlined waiver treatment from buildings of two to four units up to buildings of ten units. That is a meaningful shift for a neighborhood built on small-format conversions. A three-address grouping like the Mullen Buildings falls comfortably inside that expanded window. A 28-unit building like H2O Lofts or a 51-unit conversion like One Ecker Place does not. Those larger loft buildings lose the shortcut entirely and now need a full project review, covering owner-occupancy percentage, reserve funding, and any pending litigation, before a conventional loan can close.
The practical result is that two lofts with nearly identical finishes and nearly identical prices per square foot can sit on opposite sides of a financing line drawn by unit count alone. A prior owner in the same building having closed with a conventional loan last year no longer tells you anything, since the review pathway that let that happen may not exist anymore.
What This Means If You're Buying or Selling a SoMa Loft Now
If you're the buyer, ask these questions before you write an offer, not during your loan contingency period:
- How many units does the building have, and does it fall inside or outside the new ten-unit waiver threshold
- Has the HOA completed a Fannie Mae Condo Project Manager or Freddie Mac Condo Project Advisor review, and when
- Does the unit's title or 3R report still reference a live/work or artist-occupancy designation from its original zoning
- What is current owner-occupancy percentage, and has any special assessment been proposed or funded
If you're selling a loft in one of SoMa's larger converted buildings, this is worth raising with your HOA board proactively. A building that clears a Full Review calmly, with clean reserves and documented owner-occupancy, keeps its full pool of conventional buyers. One that stalls in review sees that pool shrink to portfolio and non-warrantable lenders, which tends to show up in both price and days on market.
Frequently Asked Questions
Does the August 2026 financing change apply to TICs too? No. TICs already use fractional financing through a smaller pool of specialized lenders rather than standard Fannie Mae or Freddie Mac condo review, so the Limited and Streamlined Review elimination does not change TIC underwriting directly. It affects buildings that are titled as condominiums.
Is a live/work loft automatically harder to finance than a regular SoMa condo? Not automatically. The building's unit count, age, HOA financial health, and prior review status matter more than the live/work label itself. A smaller loft building that now qualifies for the expanded waiver threshold can actually be easier to finance than a larger, newer condo tower still working through a Full Review backlog.
Should I still buy a converted loft in a large building like H2O Lofts or One Ecker Place? These remain desirable, architecturally distinct properties, and plenty of buyers finance them successfully. The point is timing your due diligence. Confirm the building's current review status with your lender before you're deep into escrow, since the pathway that worked for a neighbor's purchase last year may no longer apply.
SoMa's loft inventory carries real character that a neighborhood of standardized condo towers cannot replicate. What has changed is how much that character costs to finance, and that cost now depends on a number, the unit count on the building's title, that most buyers never think to ask about at the open house.
