California Housing Update: SB 79 and New Condo Rules

California Housing Update: SB 79 and 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 set of Fannie Mae policy updates that remove 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 Loosened Condo Financing Rules

The same period brought a set of Fannie Mae condo guideline changes that matter a lot in California. The headline for California owners and buyers: the investor-concentration cap that used to block conventional financing in heavily-rented buildings has been removed for established projects, and master-insurance documentation rules got more flexible — both meaningful in dense metros like Los Angeles, San Francisco, and San Diego where many condo buildings exceed 50% investor ownership.

Some of these changes also tighten the other direction later in 2026 and 2027, so timing matters.

We cover the full set — what loosened, what's tightening, and the exact dates — in our condo guideline breakdown. Rather than restate the figures here (and risk two pages drifting out of sync), that article is the single source of truth on the condo rules.

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 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, a building that was non-warrantable last year may produce a conventional loan now — potentially saving you from a higher-rate non-warrantable condo loan.

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 the recent or upcoming changes may resolve the problem. We can check your building's eligibility and tell you where things stand.

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 are newly financeable are the most immediate opportunity.
