California Housing Update: SB 79 Transit Housing + New Condo Rules
Two changes are converging that affect California homebuyers and condo owners. One is a state law — SB 79 — that streamlines housing development near transit stations. The other is a Fannie Mae policy update that removes longstanding barriers to condo financing. Together, they should expand inventory and improve access to conventional mortgage financing in the state's most supply-constrained markets.
SB 79: Transit-Oriented Development
California Senate Bill 79 takes effect on July 1, 2026. The law creates a streamlined approval process for housing projects built within a half-mile of major transit stations in eight counties: Los Angeles, Orange, San Diego, San Bernardino, Riverside, San Francisco, Alameda, and Santa Clara.
What SB 79 Does
- Allows increased density for residential projects near qualifying transit stops
- Reduces or eliminates minimum parking requirements for transit-adjacent developments
- Streamlines the local approval process — qualifying projects get ministerial (by-right) approval
- Applies to both rental and for-sale housing, including condominiums
- Requires an affordability component for projects above a certain size
For buyers, SB 79 means more condos and townhomes coming to market in transit-rich areas over the next few years. For existing condo owners near transit, it could mean increased competition but also improved neighborhood amenities and property values as areas densify.
Fannie Mae Condo Rule Changes (LL-2026-03)
Fannie Mae Lender Letter 2026-03 overhauls several condo project eligibility rules that have blocked financing in California buildings for years. Here's what's changing.
| Change | Old Rule | New Rule | Effective |
|---|---|---|---|
| Investor concentration | Blocked if >50% investor-owned | Limit retired entirely | Aug 1, 2026 |
| Insurance relief | Full replacement cost required | Allows gap coverage and alternative structures | Aug 1, 2026 |
| Deductible cap | $10,000 or 1% of coverage | Raised to $25,000 or 5% of coverage | Aug 1, 2026 |
| Project review waiver | Limited to established projects | Expanded to more project types and LTV tiers | Jan 1, 2027 |
The investor concentration change alone is significant. In cities like Los Angeles, San Francisco, and San Diego, many condo buildings exceed 50% investor ownership — especially smaller buildings with 10–20 units. Under the old rule, buyers in those buildings couldn't get conventional financing. That restriction goes away on August 1.

The Combined Effect
These two changes work in tandem. SB 79 will produce more condo and townhome inventory near California transit stations over the coming years. The Fannie Mae condo rule changes make it easier to finance those units — and the existing units in buildings that were previously blocked.
For buyers, this means more options and fewer financing dead ends. For existing condo owners who've been stuck with unfavorable loan terms because their building failed Fannie Mae's project review, refinancing may finally become an option.
The impact will be felt most in California's dense metro cores — downtown LA, San Francisco, Oakland, San Jose, and San Diego — where both transit access and condo concentration are highest.
What's Coming — Timeline
| Date | What Happens |
|---|---|
| July 1, 2026 | SB 79 takes effect — transit-oriented development streamlining begins in 8 counties |
| August 1, 2026 | Fannie Mae retires investor concentration limit, implements insurance relief and deductible cap changes |
| January 1, 2027 | Expanded project review waivers take effect — more condos eligible for streamlined financing |
What This Means for You
If you're buying a condo in California: Check whether your target building was previously blocked by investor concentration rules. If so, you may want to time your purchase for after August 1 when conventional financing becomes available, potentially saving you from higher-rate non-warrantable condo loans.
If you own a California condo and want to refinance: If your building failed Fannie Mae project review due to investor concentration, insurance issues, or deductible caps, one of these upcoming changes may resolve the problem. We can check your building's eligibility and tell you which date to target.
If you're looking at new construction near transit: SB 79 will bring more options to market, but the first projects under the new streamlined process won't deliver units for 18–24 months. In the meantime, existing transit-adjacent condos that become newly financeable on August 1 are the most immediate opportunity.
