Local Market Data
San Diego County Apartment Market
Figures gathered October 2026 from public market data.
If you plan to sell commercial property in San Diego County, CA, price it against a renter-heavy market: 45.4% of the county's 1,171,278 occupied homes are renter households, and median gross rent has climbed to $2,246, up 35.5% from the 2015-2019 period, per the Census Bureau's 2020-2024 American Community Survey. Only 3.9% of rental units sit vacant, and 57.8% of renters are cost-burdened, paying 30% or more of income toward rent.
Apartment buyers across San Diego County are underwriting tight vacancy against slower population growth (down 0.8% since 2015-2019) and rising incomes (up 34.6%, to a $106,268 median). For an owner weighing an exit, that combination of strong rent growth and thin vacancy is usually a selling point buyers will pay for, provided the numbers are documented clearly from the start.

Property taxes and assessment in San Diego County
San Diego County assesses apartment buildings under California's Proposition 13 framework: a property is valued at its purchase price when it last changed hands, then that assessed value can rise by no more than 2% a year (or the rate of inflation, whichever is lower) until the next sale triggers reassessment to current market value. The base levy is 1% of assessed value, plus voter-approved bond and district overrides that vary by Tax Rate Area, so combined rates commonly land between 1.0% and 1.3% in San Diego County.
A sale in San Diego County also triggers the county's documentary transfer tax of $0.55 per $500 of consideration, under Revenue and Taxation Code Section 11911 and County Ordinance 9889. Sellers should confirm their property's specific Tax Rate Area and current assessed value with the San Diego County Assessor's office before pricing an exit.
What this means if you sell in San Diego County
For an owner looking to sell commercial property in San Diego County, CA, the current market favors sellers of occupied, cash-flowing multifamily assets: vacancy near 3.9% and rent growth above 35% over five years give buyers confidence in near-term income. Selling an apartment building in San Diego County works best when rent rolls, the Prop 13 assessed-value history and any AB 1482 just-cause exposure are documented up front.
A multifamily buyer in San Diego County will weigh rent-burdened tenants (57.8% paying 30%+ of income) against the county's limited vacancy and income growth. Owners across San Diego County who want a direct, documented cash offer rather than a drawn-out marketing process can get a faster read on value by sharing current rent rolls and expenses.
