San Francisco vs Santa Clara County: which is better for Airbnb investment?

Head-to-head metrics

Full analysis: San Francisco vs Santa Clara County

On the money side of this comparison — what a listing actually earns against the nights it has available — San Francisco finishes decisively ahead of Santa Clara County. Revenue per available night — rate and occupancy combined, the figure that actually reaches an owner — is 177.5% higher in San Francisco: £47 against £17. San Francisco sells 19 more points of its calendar — 55% median occupancy against 36% in Santa Clara County. That is not a rounding difference, and it compounds over a hold period.

San Francisco takes both halves of the yield equation, which is less common than it sounds. It charges more per night — £121 against £90 — and still fills more of the year, 55% 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 £47 against £17.

That verdict needs a caveat, because Santa Clara County is not simply the weaker market of the two. Santa Clara County's calendar is the flatter of the two — 18.5 points between its best and worst month against 26.7 in San Francisco — which makes debt service easier to underwrite. Santa Clara County sits at the cheaper end at £90 a night against £121, 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.

We hold a verified regulation record for only one side of this pairing. San Francisco caps entire-home letting at 90 nights a year and requires a licence, on a high risk rating. Santa Clara County should be read as unverified rather than unregulated: check the local authority's own register before you underwrite anything there.

The two calendars also behave differently. San Francisco peaks in November at 65.3% and bottoms in April at 38.6%; 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 26.7 — easier to underwrite against a mortgage — while San Francisco 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 Francisco suits an owner who expects to use the property personally for part of the year, or to run a hybrid calendar around the 90-night ceiling. Santa Clara County suits buyers who want a conventional, lightly regulated entry. Every figure above comes from the same Inside Airbnb snapshot pipeline on both sides, dated 2025-11, filtered to listings with at least one booking in the last twelve months. Occupancy medians are drawn from 1,763 active San Francisco listings and 2,801 in Santa Clara County.
