92620 at a glance
ZIP code 92620 is one of Irvine's newer residential footprints. Most of the housing stock was built between 2003 and 2018, with Portola Springs Village the dominant neighborhood. Detached single-family homes make up the majority of the inventory, with a smaller share of attached townhomes and condos clustered near the village center.
As of January 2026, the median sale price in 92620 is approximately $1.45 million, up roughly 4.2% year-over-year. Days on market average 24 — faster than the Orange County average of 37. The price-per-square-foot range for detached homes runs $560 to $720 depending on lot size and view.
What drives Portola Springs home values
Three factors do most of the heavy lifting on price in this ZIP:
- Irvine Unified School District boundaries. Homes assigned to Portola High School, Jeffrey Trail Middle, and Cadence Park Elementary consistently command a 6-9% premium over comparable homes in adjacent villages. See our Irvine school district homes guide for the boundary map.
- Lot size and usable yard. Portola Springs lots range from 3,500 to over 10,000 sq ft. Larger pie-shaped lots on cul-de-sacs trade at a meaningful premium — often $150K-$300K over standard interior lots.
- Newer construction premium. Because most of the inventory is under 25 years old, buyers expect modern floor plans, three-car garages, and attached casitas. Older 1990s homes on the western edge of the ZIP price slightly below the median.

What your Portola Springs home is worth — really
Online estimates (Zillow, Redfin, Realtor.com) are a starting point, not a valuation. They routinely miss:
- Lot premium for cul-de-sac or pie-shaped lots
- Pool and landscaping investments ($40K-$120K value add)
- Solar ownership vs. lease status (owned solar adds ~3% in 92620)
- ADU or casita additions (a permitted casita adds $80K-$150K)
- Interior condition and whether the home has been updated since 2015

Selling costs to plan for in 92620
If you're thinking about selling in 2026, expect total selling costs of roughly 7-9% of sale price. That breaks down to 5-6% agent commission (split between listing and buyer's agent), 1-1.5% escrow and title, and 0.5-1.5% for staging, repairs, and concessions. On a $1.5M sale, that's roughly $105K-$135K in total costs.
The full breakdown — including where you can save — is in our Selling Cost Guide. The biggest lever most sellers miss is staging: in 92620, staged homes sell 11 days faster and for 1.4% more on average.
2026 outlook for 92620
Inventory in 92620 is tight. As of January 2026, there are roughly 28 active listings in the ZIP — about 2.1 months of supply. A balanced market is 6 months. That inventory shortage, combined with continued demand from tech and biotech buyers relocating to Irvine, supports our forecast of 3-5% price appreciation through 2026.
The main downside risk is mortgage rates. If 30-year fixed rates climb back above 7.5%, affordability in 92620 tightens and price growth could flatten. Our base case is rates holding in the 6.25-6.75% range, which is consistent with continued modest appreciation.
