Southern California Housing Is Moving Differently by County

What is the direct answer about Southern California housing in July 2026?

Southern California did not move as one housing market in July 2026. The California Association of REALTORS July 2026 Home Sales and Price Report reported a regional median sales price of $899,000, up 2.7 percent from one year earlier, while regional sales were up 0.1 percent.

The county comparison was much wider. Price, sales, inventory and market time did not move in one uniform direction, so the regional average should be treated as context rather than as the final answer for a county specific housing decision.

Median sales price is the midpoint of the homes that sold during the reporting period. It is sensitive to the mix of transactions and is not a same home appreciation measure. Sales activity here is completed existing single family detached transaction volume compared with the same month one year earlier.

How different were county price and sales changes?

The seven counties produced an 8.3 percentage point spread in median price changes and a 26.9 percentage point spread in sales changes in July 2026. That range is why a regional headline can miss the direction of the county relevant to the reader.

Los Angeles County recorded an $888,120 median sales price, down 2.6 percent, while sales were down 0.9 percent. Orange County recorded a $1,475,000 median sales price, up 5.4 percent, while sales were up 0.6 percent. Riverside County recorded a $649,000 median sales price, up 3.0 percent, while sales were down 2.6 percent.

San Bernardino County recorded a $488,280 median sales price, up 0.4 percent, while sales were up 4.5 percent. San Diego County recorded a $1,099,500 median sales price, up 5.7 percent, while sales were up 4.5 percent. Ventura County recorded a $950,000 median sales price, up 0.1 percent, while sales were down 0.3 percent.

Imperial County recorded a $412,250 median sales price, down 0.7 percent, while sales were down 22.4 percent. C.A.R. cautions that outsized percentage changes in smaller counties can reflect lower transaction volume and changes in sales mix, so Imperial County should be interpreted with particular care.

Southern California was not moving in one direction at the county level. The regional aggregate described the region, but it did not describe every county.

What was happening in Riverside County?

Riverside County showed a split signal in July 2026. Its median sales price reached $649,000, up 3.0 percent from one year earlier, while sales declined 2.6 percent.

Compared with Southern California, Riverside County's median price change was 0.3 percentage points higher, while its sales change was 2.7 percentage points lower. Compared with the Inland Empire aggregate, Riverside County's price change was 1.1 percentage points higher and its sales change was 1.1 percentage points lower.

Riverside County was slightly stronger than the Southern California aggregate on median price change and weaker on transaction activity. Those are separate measures and neither establishes the cause of the other.

Was housing inventory increasing across Southern California?

No, not when July inventory is measured with C.A.R.'s Unsold Inventory Index. The index was lower than one year earlier in six of the seven counties, while Imperial County was the exception.

Riverside County moved from 4.2 months in July 2025 to 3.8 months in July 2026. Los Angeles moved from 3.7 to 3.5 months, Orange from 3.3 to 3.1, San Bernardino from 5.2 to 4.5, San Diego from 3.5 to 2.9 and Ventura from 3.5 to 3.2. Imperial County increased from 2.3 to 3.4 months.

The Southern California aggregate moved from 3.8 months to 3.4 months. The Inland Empire moved from 4.5 months to 4.1 months. The latest July reading also fits inside a longer July history from 2017 through 2026 for the six counties carried in the current historical comparison.

The defined months of supply measure tightened in most counties even though sales and price changes were mixed. That does not mean every city, neighborhood or price range became more competitive.

What does the Unsold Inventory Index actually measure?

The Unsold Inventory Index estimates how many months it would take to sell available housing supply at the current sales pace. It is a months of supply metric, not a direct count of active listings.

The index can change because available supply changes, because the sales pace changes, or because both change. A lower reading therefore should not be translated automatically into a claim that the raw number of listings fell.

The Unsold Inventory Index is best used as a pace adjusted supply measure. It should be interpreted with sales activity and other local evidence rather than as a raw inventory count.

What did market time show in July 2026?

Median market time was shorter than one year earlier in all seven counties. Riverside County moved from 40 days to 39 days.

Los Angeles moved from 27 days to 26, Orange from 28 to 26, San Bernardino from 35 to 34, San Diego from 24 to 19, Ventura from 41 to 36 and Imperial from 25 to 16.

Median market time is the midpoint of the reported market times in the transaction set. It is a pace measure and does not guarantee how long an individual property will take to sell. Market time moved in the same general direction across all seven counties even though price and sales outcomes remained mixed.

Why can a county median price rise while sales fall?

Median sales price and sales volume measure different things. The median price describes the midpoint of completed transactions, while sales volume describes how many transactions closed.

Riverside County is a clear example. Its July 2026 median sales price was up 3.0 percent from one year earlier while sales were down 2.6 percent.

A change in the mix of homes that sold can move the median. A change in completed transaction count can move sales volume. The two observations can be true at the same time without establishing that one caused the other.

A higher median price does not by itself prove stronger demand, and lower sales do not by themselves prove weaker prices. The measures should be read together without causal overstatement.

What does the longer FHFA price history tell us?

The longer history shows substantial house price index growth across all seven counties from 2015 through 2025. The Federal Housing Finance Agency House Price Index is an index based on sales price and appraisal information associated with mortgages purchased or guaranteed by Fannie Mae and Freddie Mac. It is not a dollar price series.

Publication 004 rebases each county's Annual County All Transactions HPI to 2015 equal to 100. Riverside County finished 2025 at 205.4, above the seven county median of 199.1 and below the range high of 209.0.

Riverside County tracked near or above the seven county median across the verified historical comparison, but FHFA HPI should not be substituted for the current C.A.R. median sales price.

How far had county positions separated from the seven county median by 2025?

County positions had separated materially from the seven county rebased HPI median by 2025. Imperial County was 9.9 index points above the median, Riverside County was 6.3 above and San Bernardino County was 3.7 above.

San Diego County was at the median. Orange County was 10.1 points below, Los Angeles County was 12.2 below and Ventura County was 21.2 below.

The county positions diverged meaningfully from the common median after 2020, but the chart describes relative index positions rather than future performance or individual property appreciation.

What does the full seven county FHFA history show?

All seven counties recorded substantial increases in the rebased FHFA index from 2015 through 2025. The 2025 endpoints ranged from 177.9 in Ventura County to 209.0 in Imperial County.

Imperial finished at 209.0, Riverside at 205.4, San Bernardino at 202.8, San Diego at 199.1, Orange at 189.0, Los Angeles at 186.9 and Ventura at 177.9.

Those endpoints represent cumulative rebased gains of about 109.0 percent for Imperial, 105.4 percent for Riverside, 102.8 percent for San Bernardino, 99.1 percent for San Diego, 89.0 percent for Orange, 86.9 percent for Los Angeles and 77.9 percent for Ventura.

Every county experienced substantial index growth in the verified historical window, but the size of the increase differed. The historical ranking does not forecast which county will outperform next.

Do Riverside County numbers describe Menifee, Murrieta or Temecula?

No. Riverside County data provides county level context and cannot be assigned directly to Menifee, Murrieta, Temecula, Perris, Wildomar, San Jacinto or another individual city without comparable city level evidence.

A Southwest Riverside buyer still needs evidence for the actual property, city, community, price range, financing structure and local competition. A homeowner still needs current comparable transactions, property condition and local supply before drawing a value conclusion.

Riverside County is the correct local anchor for this regional comparison, but city and property decisions require separately verified local evidence.

What could change the current interpretation?

A newer monthly county release could change the relationship among price, sales, inventory and market time. A future FHFA revision could change exact historical index values or relative positions.

Separately verified city evidence could also support a more specific Southwest Riverside conclusion than the current county evidence allows. Local transaction mix, financing conditions and property specific competition could change the practical interpretation for an individual decision without changing the county statistics themselves.

The current interpretation should change when the underlying county evidence changes or when better matched local evidence becomes available.

What should readers watch next?

Watch the next official county release to see whether the July divergence persists, narrows or changes direction. Track median price, sales, the Unsold Inventory Index and median market time as separate measures.

For Riverside County and Southwest Riverside, pair county evidence with current local and property specific information before acting. Continue through the CMN Research Library, compare current options through Property Search, or request a more focused CMN housing intelligence brief.

The next useful question is not whether Southern California is up or down. It is whether the county and local evidence relevant to the decision are moving in the same direction.
