Q3 2026 · County Overview
San Diego County multifamily is not one market in 2026 — it is two, moving in opposite directions. New Class A delivery downtown and inland pushed countywide vacancy to 5.0% and dragged the average sale price per unit down 18.9% year over year to roughly $271,747. Over the same period, Class B and C workforce housing held near 3.3% vacancy while Class A sat closer to 6.4%.
That gap is the single most useful fact in the county right now. The supply-constrained coastal and urban-core submarkets — where the inventory is vintage two-to-twelve-unit product that cannot be replicated — largely sat out the correction. The repricing happened where the cranes were.
For buyers, the practical consequence is that headline county averages are close to useless for underwriting a specific deal. A fourplex four blocks from the sand in 92109 and a 230-unit lease-up downtown are not in the same market, and should not be priced off the same comp set. The submarket pages below exist for exactly that reason.
Figures reflect the Q3 2026 reporting cycle and are compiled from third-party rental-market data aggregators, published San Diego County multifamily research, municipal and state regulatory records, federal loan-limit tables, and ARG proprietary transaction data. A full citation appendix is maintained for every page and is available on request.
Where We Work
Cap rates, rents and ADU capacity move block by block. Each page carries current numbers, recent trades and the regulatory detail that actually affects what a parcel is worth.
Pacific Beach
Avg rent $2,819 · 69% renters
Supply-locked coastal peninsula. Vintage 2–4 unit stock, deep owner-occupant exit demand.
Ocean Beach
Coastal · Low turnover
Community-embedded tenant base and lower per-door entry pricing than Pacific Beach.
La Jolla
Lowest caps in the county
Trophy coastal assets, thin inventory and buyers who compete on location, not yield.
North Park
Value-add · Growth submarket
Walkable urban core with the county's most active small-multifamily renovation pipeline.
Hillcrest
Density bonus upside
Transit-adjacent parcels where zoning, not rent growth, drives the value-add thesis.
Mission Hills
Historic stock · Tight supply
Period architecture and long-hold family ownership; most trades happen off-market.
Normal Heights
Workforce housing · ~3.3% vacancy
Class B/C income property with the steadiest occupancy profile in the county.
Chula Vista
South Bay · Higher yields
Bayfront redevelopment and the widest cap-rate spread to the coastal submarkets.
Reports & Briefings
Quarterly county reports plus short briefings whenever a rule change moves the numbers. Every figure is traceable to a dated source.
Vacancy tightens to 5.0% while price per unit falls 18.9% year over year. Why the two numbers are not contradictory, and what the Class A/B split means for underwriting.
Rents, cap rates, per-door pricing and the 2026 ADU unit caps, including why the Coastal Zone status leaves a live window for 92109 owners.
The bonus programme ended in June 2025 and was replaced with hard lot-size caps. A plain-language briefing on what can still be built, and where the Coastal Commission backlog creates opportunity.
The San Diego cap steps down to 8.2% on 1 August 2026. What that means for pro forma rent growth, and why the failed 2026 tightening bill matters for planning certainty.

Methodology
Market data is only useful if you know what it counts. These are the definitions used throughout this site, applied consistently so figures can be compared across quarters and submarkets.
Every published figure is traceable to a dated, named source held in an internal citation appendix, one per page, furnished on request to any client, lender or counsel who asks to verify a number. On the page itself, sources are attributed by category rather than by company name — partly so pages can be refreshed without rewriting the prose around a vendor's publishing schedule, and partly because ARG does not advertise competing brokerages inside its own research.
Government bodies, statutes and regulators are always named. Where a figure is ARG's own analysis rather than a published statistic, it is labelled as such.
