Full analysis: San Diego vs Santa Clara County

On the money side of this comparison — what a listing actually earns against the nights it has available — San Diego finishes decisively ahead of Santa Clara County. Revenue per available night — rate and occupancy combined, the figure that actually reaches an owner — is 168.2% higher in San Diego: £45 against £17. San Diego sells 12 more points of its calendar — 48% median occupancy against 36% in Santa Clara County. That is not a rounding difference, and it compounds over a hold period.

San Diego takes both halves of the yield equation, which is less common than it sounds. It charges more per night — £137 against £90 — and still fills more of the year, 48% against 36%. A market that leads on price and utilisation at once is normally one where demand has outrun supply, rather than one where hosts are discounting to keep the calendar busy. RevPAR reflects the double advantage at £45 against £17.

That verdict needs a caveat, because Santa Clara County is not simply the weaker market of the two. Santa Clara County is the less crowded of the two — 4,277 active listings to 9,541 — so a well-run property has fewer near-identical rivals to out-rank. Santa Clara County sits at the cheaper end at £90 a night against £137, which lowers the bar for filling shoulder-season dates and usually tracks a lower purchase price too. If your model leans on that dimension, the ordering above can reasonably flip.

Neither San Diego nor Santa Clara County currently has a verified short-term rental regulation record in our register, so the comparison above is a yield comparison only. Regulation is the single largest source of downside in this asset class — an unverified market is an unpriced risk, not an absent one.

The two calendars also behave differently. San Diego peaks in September at 52.6% and bottoms in December at 31%; Santa Clara County runs from 53.5% in November down to 35% in April. Santa Clara County is the steadier of the two at 18.5 points peak-to-trough against 21.6 — easier to underwrite against a mortgage — while San Diego concentrates its return into a shorter window and rewards operators who price the peak aggressively instead of holding a flat rate all year.

Who each suits, then. San Diego suits buyers who want a conventional, lightly regulated entry. Santa Clara County answers to the same regulatory profile, so the split between them is operational rather than legal. Every figure above comes from the same Inside Airbnb snapshot pipeline on both sides, filtered to listings with at least one booking in the last twelve months. Occupancy medians are drawn from 4,203 active San Diego listings and 2,801 in Santa Clara County.

Frequently asked questions

Is San Diego or Santa Clara County better for Airbnb investment?
San Diego, on the data we track. It leads on stronger RevPAR (£45 vs £17), higher occupancy (48% vs 36%), and a higher nightly rate (£137 vs £90). Santa Clara County is not the weak side of this pair, though — it wins on a thinner competitive field (4,277 vs 9,541 active listings).
Which has higher occupancy, San Diego or Santa Clara County?
San Diego, at 48% median occupancy against 36% in Santa Clara County — a gap of 12 points. That is a wide spread by short-term rental standards and usually reflects a structural demand difference rather than better hosting.
Which has higher nightly rates, San Diego or Santa Clara County?
San Diego, at £137 a night against £90 in Santa Clara County — roughly 52.6% more. Revenue per available night agrees rather than contradicts: £45 in San Diego against £17, so the rate premium survives contact with the occupancy figures.
Which has stronger year-over-year growth, San Diego or Santa Clara County?
We can only measure one side, so this comparison stays open. Santa Clara County moved +17.9 points on occupancy year over year. San Diego lacks a comparable snapshot from roughly twelve months earlier, and we would rather leave the cell empty than compare against a mismatched date.
Which is the bigger Airbnb market, San Diego or Santa Clara County?
San Diego, with 9,541 active listings against 4,277 in Santa Clara County. Size cuts both ways: a deep market gives you comparables, contractors and an exit, while a thinner one means fewer near-identical rivals competing for the same search results.
How much can you earn from an Airbnb in San Diego vs Santa Clara County?
San Diego earns more: roughly £16,539 a year for a median listing against £6,179 in Santa Clara County. Those are gross booking revenues before cleaning, management, platform fees, furnishing amortisation and tax — budget for a meaningful share of them, and note that a median listing is a median operator, not a good one.
