San Francisco has one of California’s highest concentrations of condo inventory — and some of its oldest. The city’s dense residential fabric includes thousands of condo conversions, loft buildings, stacked flats, and multi-unit developments dating from the early 1900s through the 1980s. Many of these buildings have balconies, elevated walkways, and exterior decks that are now subject to mandatory SB 326 structural inspection — and a significant number are coming back with findings that are disrupting conventional financing throughout the Bay Area.

DiVita Home Finance serves condo buyers across San Francisco, Marin County, and the East Bay. Here’s what you need to know.

San Francisco’s SB 326 Exposure: Why It’s Larger Than Most Cities

Several factors make San Francisco particularly vulnerable to SB 326 financing disruption:

Building age: A large percentage of SF’s condo inventory was built before 1990. Older structures have had more time for wood rot, moisture intrusion, and structural fatigue — precisely what SB 326 inspections are designed to find.
Marine environment: San Francisco’s foggy, salt-air climate accelerates corrosion and wood deterioration compared to drier inland markets. Balconies and elevated walkways take a harder beating here.
Condo conversion density: Much of SF’s condo stock began as apartment buildings converted to TIC (tenants-in-common) and eventually condominiums. These conversions often didn’t include comprehensive structural updates.
High prices raise the stakes: When a $1.2 million SF condo can’t be financed conventionally because of SB 326, the impact on buyers and sellers is enormous. The premium market makes non-warrantable situations especially costly.

Marin County: Waterfront Condo Risk

Sausalito, Mill Valley, and Tiburon have significant condo and townhome inventory — particularly waterfront and hillside buildings where moisture, salt air, and challenging terrain create elevated structural risk. Marin’s higher price points mean SB 326 issues carry even higher financial stakes than in more affordable markets. A non-warrantable $900,000 Sausalito waterfront condo affects a very different population of buyers than a $400,000 inland condo — and the financing solutions need to match.

East Bay: Older Stock and Dense Urban Inventory

Oakland and Berkeley have extensive condo, loft, and converted building inventory — much of it older — with a wide range of balcony and elevated element configurations. Berkeley’s older Craftsman-era converted buildings, Oakland’s loft districts, and the corridor along Lake Merritt all have meaningful SB 326 exposure. East Bay condos at more accessible price points also attract first-time buyers who need FHA financing — exactly the buyers most affected when buildings become non-warrantable.

Financing Solutions for Bay Area SB 326 Situations

Portfolio Loans — The Primary Solution

Portfolio lenders are the most practical tool for Bay Area buyers dealing with SB 326 non-warrantable status. These lenders use their own underwriting criteria and can approve financing in buildings Fannie Mae and Freddie Mac decline. For San Francisco’s higher price points, jumbo portfolio programs are available that extend well above conventional loan limits.

Rate premium is typically 0.50–1.25% above market. On a $1.2M SF condo financed at 80% LTV ($960,000 loan), that’s roughly $400–$1,000/month in additional payment — significant, but often far less than the price discount available on non-warrantable units where the buyer pool is limited.

Non-QM Condo Programs

Non-QM investors offer programs specifically for non-warrantable condos that don’t require HOA warrantability approval. For self-employed SF buyers — a significant portion of the tech-driven Bay Area buyer population — non-QM bank statement programs combine SB 326 non-warrantable flexibility with alternative income documentation.

FHA Spot Approval for East Bay First-Time Buyers

FHA Single Unit Approval (spot approval) can allow FHA financing — 3.5% down, lower credit score thresholds — in buildings without full FHA project approval. For East Bay and South Bay first-time buyers in buildings with SB 326 complications, spot approval is sometimes the only path to low-down-payment financing. Eligibility depends on specific building conditions — we evaluate case by case.

Jumbo Portfolio for High-Value SF Condos

San Francisco’s high price points often push purchases into jumbo territory — above the 2026 conforming limit of $806,500. Jumbo portfolio programs for non-warrantable condos require 20–25% down, 700+ credit scores, and strong income documentation, but they exist and we work with them regularly for SF buyers.

The Negotiation Opportunity in Non-Warrantable Bay Area Condos

Here’s the flip side of the SB 326 problem for smart Bay Area buyers: non-warrantable condos sell at a discount because most buyers can’t finance them. The buyer who can — through a portfolio or non-QM program — has far less competition. In a market like San Francisco where every percentage point of purchase price matters, buying a non-warrantable condo at a 10–15% discount and financing it at a rate premium can still come out ahead financially.

We help buyers run these numbers — the true all-in cost comparison between a conventional condo at full price versus a non-warrantable unit at a discount with a portfolio loan. Call us before you walk away from a building with SB 326 issues.
