Orange County ZIP Codes: Home Values and What Each ZIP Covers

All 86 Orange County ZIP codes at a glance

Zillow tracks home values in 86 ZIP codes in Orange County. We matched each one to cities and census places with the Census Bureau's 2020 ZIP code tabulation area to place file, which measures how much of each ZIP's land falls in each place. The second column shows the places that hold at least 3% of a ZIP's land, plus the unincorporated share where it is 10% or more. Values are Zillow's typical home value for September 2026; sales are Redfin's figures for the three months to September 2026.

Zillow's typical value estimates every home in the ZIP, sold or not, while Redfin's median covers only the homes that sold, so the two can differ widely where a quarter's sales were mostly condos or mostly large houses. Use each source on its own; don't compare a Zillow figure in one ZIP with a Redfin figure in another. "n/a" means too few sales for Redfin to report. Countywide, Zillow's typical value was $1,174,873 in September 2026, up 3.2% in a year, and the median ZIP sat at about $1.2 million. 63 of the 86 ZIPs were at $1 million or more.

Orange County ZIP codes by city

Each group below covers one city or a few neighboring ones. Every line gives the ZIP's Zillow typical value and one-year change, Redfin's three-month median sale price, number of sales and median days to go under contract, and the Census Bureau's 2020-2024 population and owner-occupied share for the ZIP code tabulation area.

Irvine ZIP codes: 92602 to 92620

Newport Beach ZIP codes: 92625, 92657, 92660 to 92663

Newport Beach holds the five most expensive ZIPs in the county on Zillow's measure, and the fastest gains: 92661 rose 15.0% and 92662 14.1% in a year. Each had only about 15 sales in three months, so their Redfin medians swing from quarter to quarter. 92657 is the highest-valued ZIP in Orange County at $5,547,446. 92662 covers about 0.2 square miles. Our Newport Beach ZIP code guide has more.

Fullerton, Brea and La Habra ZIP codes

North county's three hill-and-flatland cities. 92823, Brea's second ZIP, is 57% unincorporated by land and had only 9 sales in three months, so lean on Zillow's figure there. 90631 straddles the county line: 54% is La Habra in Orange County and 44% is La Habra Heights in Los Angeles County, so the county on the deed sets your tax rate and services.

• 92831: Zillow $1,055,747 (+3.9% in a year); Redfin median $1,054,690 on 57 sales, 37 days to contract; 35,618 residents, 41% of homes owner-occupied, median rent $2,146.

Westminster, Midway City, Stanton and Fountain Valley ZIP codes

92655 is 67% Midway City, an unincorporated community, and 33% Westminster; with only 7 sales, its Redfin median says little. Stanton's 90680 is the county's third-lowest ZIP on Zillow's measure. Fountain Valley's 92708 sold in a median of 27 days, second-fastest among ZIPs with 20 or more sales.

Seal Beach, Los Alamitos and Rossmoor ZIP codes

90740's low Redfin median reflects its sales mix. It includes Leisure World Seal Beach, a gated 55-plus community of condos and co-ops on 531 acres, so many sales there are age-restricted units; compare single-family sales separately. 90720 is 66% Los Alamitos, 26% Rossmoor (unincorporated) and 8% Cypress.

Orange, Villa Park and North Tustin ZIP codes

92867 and 92869 are about a third and a half unincorporated land, so the same mailing city can mean county services and a different tax rate area. Villa Park's 92861, about 2 square miles, ranks just behind the Newport Beach and Laguna Beach ZIPs at $2,332,953. 92705 is 49% North Tustin, 39% Santa Ana and 5% Tustin.

Lake Forest, Laguna Hills, Laguna Woods and Aliso Viejo ZIP codes

92637 is the lowest-valued ZIP in the county by far. It includes Laguna Woods Village, a private 55-plus community, so its values describe age-restricted housing; they are not a cheap entry into south county for buyers who don't meet the age rule. Lake Forest's 92610 fell 2.3% on Zillow's measure, one of the few declines outside Irvine. 92656 is 14% unincorporated land.

Mission Viejo and Rancho Santa Margarita ZIP codes

92688 is 75% Rancho Santa Margarita, 19% Las Flores and 5% Rancho Mission Viejo, and its Redfin median sits well below Zillow's figure because of its sales mix. Mission Viejo's two ZIPs are within a few hundred dollars of each other on Zillow's measure.

Which Orange County ZIP codes cost the most and least?

On Zillow's typical value for September 2026, the five most expensive ZIPs are all in Newport Beach: 92657 at $5,547,446, 92661 at $4,704,738, 92662 at $4,647,099, 92625 at $4,342,564 and 92660 at $3,270,812. Laguna Beach's 92651 is next at $3,114,975. The least expensive is 92637 in Laguna Woods at $458,554, a figure shaped by its 55-plus community, followed by Santa Ana's 92701 at $691,334, Stanton's 90680 at $780,634, Seal Beach's 90740 at $785,134 and Irvine's 92617 at $807,527.

The year's changes split the county in two. Coastal ZIPs rose fastest: 92661 gained 15.0%, 92662 14.1%, 92663 11.1%, 92625 9.8% and 92660 9.6%. Nine ZIPs fell, led by Irvine's 92618 at 5.5%, 92620 at 2.6%, Lake Forest's 92610 at 2.3% and Irvine's 92612 at 1.4%. Most of north and central county gained between 2% and 6%.

Speed varies as much as price. Among ZIPs with at least 20 sales in the three months to September 2026, Redfin's median days to contract ranged from 26 in La Palma's 90623 and 27 in Fountain Valley's 92708 to 80 in Laguna Beach's 92651 and 81 in Irvine's 92603. Higher-priced ZIPs generally took longer.

Your mailing city may not be your city

A ZIP code is a postal route, not a boundary. In Orange County that matters more than in most places, because large areas are unincorporated: Rossmoor, North Tustin, Midway City, Ladera Ranch, Coto de Caza, Rancho Mission Viejo, Las Flores, Trabuco Canyon and the canyon communities all use mailing addresses tied to nearby cities. Whether a home is inside a city or in unincorporated county land decides who polices it, who collects the trash, which building department signs off on permits and which tax rate area it sits in.

The Orange County Auditor-Controller's 2026-27 tax rate book lists total rates from 1.0% to about 1.24% of assessed value across the county's tax rate areas, before any Mello-Roos special taxes, which are billed separately. 1.05993% is the rate shared by the largest number of tax rate areas. On a $1,174,873 assessed value, each 0.1 percentage point is about $1,175 a year. Our Orange County property tax guide shows how a bill is built, and the Mello-Roos guide covers the special taxes common in south county's newer communities.

School districts don't follow ZIPs either. The rate book index alone lists 19 school district groupings for areas outside city limits. Use the district's own address lookup for a specific home; we never say which school a home is zoned for.

How to use Orange County ZIP data

Start broad, then narrow. Use the table to set a budget and shortlist a few ZIPs, then read the city group for what each one includes. Before you make an offer, price the home from recent sales of the same type within a few blocks, because a ZIP median mixes condos, townhomes and houses.

• Look up the parcel's city and tax rate area on the county tax bill or the Treasurer-Tax Collector's site.
• Ask whether the home pays Mello-Roos or HOA dues; both vary within a ZIP.
• Check the fire hazard severity zone, flood zone and tsunami zone for the address on Cal OES MyHazards.
• Confirm the school district with the district's own lookup.
