What the Q2 2026 South Bay Apartment Market Numbers Show
This South Bay apartment market report for Q2 2026 covers sales volume, pricing, asking rents, vacancy, and the new construction pipeline across the South Bay multifamily market.
Apartment prices appear to be stabilizing
South Bay apartments sold for an average of $302,550 per unit in Q2 2026, virtually unchanged from $302,146 in the previous quarter. After values declined steadily from $314,786 per unit, two consecutive quarters of stable pricing suggest the market may be finding a floor.
Multifamily sales activity is beginning to recover
Year-over-year sales volume was down 21.6%, but that comparison is somewhat misleading. Q2 2025 was an unusually active period, with transaction volume running 30% ahead of the previous year.
The quarter-over-quarter trend is more encouraging. South Bay multifamily sales volume increased from $231.3 million to $245.6 million—the first quarterly gain in a year.
Apartment demand and rent growth are improving
Average asking rents reached $2,098 per month, up from $2,069 a year earlier. Rent growth has now strengthened for two consecutive quarters.
Net absorption—the number of apartment units newly occupied—rose to 88 units over the past year. That was the strongest result since Q2 2025 and a significant improvement from the low of 16 units recorded last winter. South Bay apartment vacancy also ticked down to 3.7% from 3.8% the prior quarter — still above the 3.2% of a year ago, but moving in the right direction.
The new-apartment supply pipeline is shrinking
New supply may be the most important trend to watch. Apartments under construction nearly doubled to 1,499 units last summer, but the pipeline has since declined to 1,139 units. That represents approximately 2.2% of the South Bay’s existing inventory of 51,701 apartments.
Once the current projects are completed, substantially fewer new units are expected to enter the market. That could reduce competition for existing apartment properties and support future rent growth.
What this means for South Bay apartment owners and investors
Buyers are accepting cap rates approximately 20 basis points higher than a year ago—5.2% compared with 5.0%. In return, they are entering a South Bay multifamily market where rents are rising, vacancy is stabilizing, and competing supply is declining.
The Q2 2026 picture is increasingly clear: apartment values are stable, transaction volume is turning upward, and market fundamentals are improving.
Where an individual building falls within these benchmarks will depend on its age, location, unit mix, condition, and how its current rents compare with the South Bay market average of $2,098 per month.
