Where ZIP code 91423 starts and ends

Most Sherman Oaks addresses fall in one of two ZIP codes. 91403 covers the western half and 91423 covers the eastern half. Based on the U.S. Census Bureau's ZIP Code Tabulation Area map and the Census geocoder, the boundaries of 91423 run roughly as follows:

• West: just east of Van Nuys Boulevard. Tyrone Avenue is in 91423, while addresses on Van Nuys Boulevard itself, such as the 4600 block, are in 91403. On Ventura Boulevard, the 13900 block is in 91423 and the 14500 block is in 91403.
• North: Magnolia Boulevard. The 13800 and 14300 blocks of Magnolia Boulevard and the 5100 block of Hazeltine Avenue are in 91423, while the 5200 block of Hazeltine Avenue and the 5300 block of Woodman Avenue carry ZIP code 91401, which they share with Van Nuys.
• East: north of Ventura Boulevard, just past Coldwater Canyon Avenue. The 4900 block of Coldwater Canyon Avenue, the 12900 block of Magnolia Boulevard and the 12950 block of Riverside Drive are in 91423, while the 12800 blocks of Magnolia Boulevard and Riverside Drive carry ZIP code 91607, and Whitsett Avenue is in Studio City, 91604. On Ventura Boulevard, the line falls between the 13300 block (91423) and the 13200 block (Studio City, 91604). South of the boulevard, the 4400 block of Fulton Avenue is in 91423 and the 4200 block is in Studio City.
• South: the hillside streets south of Ventura Boulevard, including the Beverly Glen Boulevard corridor, Coy Drive and the upper part of Woodman Avenue, run up toward Mulholland Drive. Farther west in the hills, Woodcliff Road is already in 91403.

The Ventura Freeway (US 101) crosses the northern part of the ZIP code. The Census tabulation area covers about 4.1 square miles of land. It is a close match to the postal ZIP code but not an exact one, so for any single address, confirm the ZIP code with the U.S. Postal Service.

How 91423 compares with 91403 and 91604

91423 has the most homes of the three ZIP codes compared here and the largest share of homes in multi-unit buildings. About six in ten homes are in buildings of five or more units, and close to two in three occupied homes are rented. It also has the oldest median year built of the three, 1966.

To the north, the 91401 ZIP code, which includes part of Van Nuys and some blocks north of Magnolia Boulevard with a Sherman Oaks mailing address, had a Redfin median sale price of $1,184,487 and a median of 48 days on market over the same three months.

Two well-known Sherman Oaks places are in 91423: Westfield Fashion Square (14006 Riverside Drive) and the Van Nuys Sherman Oaks Recreation Center (14201 Huston Street). The Sherman Oaks Galleria (15301 Ventura Boulevard) and Sherman Oaks Hospital (4929 Van Nuys Boulevard), by contrast, are in 91403.

The 91423 housing market right now

91423 has hillside houses south of Ventura Boulevard, flat single-family streets north of it, and thousands of condominiums and apartments, so the all-types median depends heavily on which kinds of homes sold in a given period. The market is best read by property type.

Source: Redfin, 91423 housing market, data through August 2026, viewed October 5, 2026. Median prices and days on market cover the three months ending August 2026; Redfin reports the homes-sold count for August 2026. Redfin figures are based on MLS and public records.

Redfin also reported these August 2026 figures for all home types in 91423: a sale-to-list price ratio of 98.4%, 28.6% of homes selling above list price (up 13.1 points from a year earlier), and 33.2% of homes with a price drop. The median sale price per square foot was $694, down 6.7% from a year earlier.

What the numbers say. On the surface, a 20.3% drop in the single-family median looks alarming. The other signals point the other way: houses sold in a median of 47 days, down from 74 a year earlier, and the share of homes selling above list price rose by 13.1 points. The price per square foot fell 6.7%, far less than the median. When the measures disagree like this, the mix of homes that sold usually explains most of it, for example fewer large hillside homes and more smaller houses on the flat streets. Condos tell a different story: fewer sold than a year earlier, they took a median of 84 days, and the median price slipped 6.0%. For a seller, that means pricing from recent sales of truly comparable homes, on the same side of Ventura Boulevard and of the same property type. For a condo buyer, it means more time to compare buildings and room to negotiate. For a house buyer, it means being ready to move on homes that are priced right.

Housing in 91423

According to the Census Bureau's 2020-2024 American Community Survey, 91423 has 16,782 housing units. About 33.7% are detached single-family houses and another 2.1% are attached single-family homes, such as townhomes. About 61.0% of all homes are in buildings of five or more units, and roughly 5,500 homes, or 32.8%, are in buildings of 20 or more units. About 37.2% of occupied homes are owned and 62.8% are rented. The ACS median year built is 1966, the median gross rent is $2,277 a month, and the median value of an owner-occupied home is $1,430,800.

In practical terms, the ZIP code has two sides. North of Ventura Boulevard, on the flat streets between Van Nuys Boulevard and Coldwater Canyon Avenue, single-family streets sit alongside blocks of condominium and apartment buildings, many of them along Moorpark Street, Riverside Drive, Magnolia Boulevard and the avenues that cross them. South of Ventura Boulevard, the streets climb into the hills toward Mulholland Drive, and the homes are almost all single-family houses, many on hillside lots. A condo on Moorpark Street and a view home off Beverly Glen Boulevard share a ZIP code but are entirely different markets.

My work in 91423

Most of my Sherman Oaks work has been here, in the eastern half. Since 2021 I have completed more than a dozen leases in 91423, on Coldwater Canyon Avenue, Landale Street, Ventura Canyon Avenue and Valleyheart Drive, most recently in 2026. Several of those were repeat leases in the same buildings, which has given me a close look at how rental demand moves here from one year to the next. I also sold a listing on Landale Street in 2015. I work with buyers, sellers, owners and tenants across all of Sherman Oaks, and I prepare every price opinion in 91423 from the recent sales and leases that match the home, not from the ZIP code median.
