Full analysis: San Francisco vs San Mateo 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 San Mateo County. Revenue per available night — rate and occupancy combined, the figure that actually reaches an owner — is 52.6% higher in San Francisco: £75 against £49. San Francisco sells 11.5 more points of its calendar — 36.2% median occupancy against 24.7% in San Mateo County. That is not a rounding difference, and it compounds over a hold period.

On the mechanics of the yield the two are hard to separate. San Francisco runs 36.2% occupancy at £194 a night; San Mateo County runs 24.7% at £200. That leaves RevPAR almost level too — £75 against £49 — so operating quality, not market selection, is what will decide your return between these two.

That verdict needs a caveat, because San Mateo County is not simply the weaker market of the two. San Mateo County is the less crowded of the two — 2,237 active listings to 4,543 — so a well-run property has fewer near-identical rivals to out-rank. Its strongest submarket, Portola Valley, clears £125 RevPAR on its own — city medians hide that kind of spread. 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. San Mateo 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 September at 67.4% and bottoms in February at 39.8%; San Mateo County runs from 57.8% in October down to 29.4% in February. Both swing by a similar amount across the year, so neither offers meaningfully steadier cash flow than the other.

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. It is also the momentum side of this pair. San Mateo 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 2026-09, filtered to listings with at least one booking in the last twelve months. Occupancy medians are drawn from 4,543 active San Francisco listings and 2,237 in San Mateo County.

Frequently asked questions

Is San Francisco or San Mateo County better for Airbnb investment?

San Francisco, on the data we track. It leads on stronger RevPAR (£75 vs £49), higher occupancy (36.2% vs 24.7%), and higher median annual revenue (£27,276 vs £17,870). San Mateo County is not the weak side of this pair, though — it wins on a thinner competitive field (2,237 vs 4,543 active listings).

Which has higher occupancy, San Francisco or San Mateo County?

San Francisco, at 36.2% median occupancy against 24.7% in San Mateo County — a gap of 11.5 points. That is a wide spread by short-term rental standards and usually reflects a structural demand difference rather than better hosting. Over the last twelve months San Francisco gained 3 points and San Mateo County gained 1.7 points, so the gap is widening.

Which has higher nightly rates, San Francisco or San Mateo County?

San Mateo County, at £200 a night against £194 in San Francisco — roughly 2.8% more. The nightly rate is not the whole story, though. On revenue per available night — rate multiplied by how often the room actually sells — San Francisco comes out ahead at £75 against £49, so San Francisco's cheaper nights are more than repaid by how often they fill.

Is San Francisco or San Mateo County riskier for Airbnb regulation?

We hold a verified regulation record for San Francisco only, so we will not rank the two. San Francisco caps entire-home letting at 90 nights a year and requires a licence, and it is rated high risk. Treat San Mateo County as unverified rather than unregulated, and check the local authority directly before committing.

San Francisco, on occupancy: +3 points over the last twelve months against +1.7 points in San Mateo County. Nightly rates rose 60.8% in San Francisco and rose 59.1% in San Mateo County over the same window. One year of movement is a direction, not a trend — weigh it against the regulation picture before treating it as momentum.

Which is the bigger Airbnb market, San Francisco or San Mateo County?

San Francisco, with 4,543 active listings against 2,237 in San Mateo 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.
