San Francisco County, California Short-Term Rental Regulations: A 2026 Guide For Airbnb Hosts

Do you own a place in San Francisco County, California and you're weighing whether to put it on Airbnb or Vrbo? Well, the good news is that short-term renting is legal here, and the city runs a real registration program you can get into. The harder news, and I'll be straight with you, is that San Francisco only lets you rent out the home you actually live in. So if you were picturing a whole condo bought only to run on nightly rates, that's not a plan this city allows, no matter how the numbers pencil out.

One thing to get clear up front, since it trips people up: San Francisco is a consolidated city and county, so "San Francisco County" and "the City and County of San Francisco" are the same jurisdiction, under one set of rules. Those rules run on your residency. You have to live in the unit at least 275 nights a year, you can host guests while you're home as often as you like, and you can rent the place un-hosted, while you're away, for no more than 90 nights a year. Everything else in this guide hangs off that one idea.

So let's walk through what it actually takes to do this properly: which units even qualify in 2026, what the certificate costs, the taxes a stay collects, how hard the city pushes when someone breaks the rules, and who to call when you get stuck. Every figure below comes from San Francisco's own pages or California state law, checked in July 2026, and where something is still shifting I've flagged it. If you're comparing a San Francisco home against markets where a whole unit can legally go on Airbnb, do run both through BNBCalc before you commit to anything.

What are Short-Term Rental (Airbnb, VRBO) Regulations in San Francisco County, California?

That residency rule I mentioned a moment ago isn't a guideline, it's the whole foundation, and it lives in Chapter 41A of the city's Administrative Code. A short-term rental in San Francisco means renting a residential unit for fewer than 30 nights, and the law only permits it when a permanent resident does it in their own home. You have to be the owner or the tenant, you have to have lived there for at least 60 days before you apply, and you have to keep living there at least 275 nights every calendar year. Rent out a second property you don't sleep in, and you're outside the law from the first booking.

The distinction that decides how much you can actually earn is hosted versus un-hosted, so it's worth getting straight before anything else. A hosted stay is one where you're in the unit overnight with your guest, and there's no annual cap on those. An un-hosted stay is one where you're away while the guest has the place, and San Francisco lets you do that for only 90 nights per calendar year. That 90-night limit is cumulative across Airbnb, Vrbo and every other channel combined, so you can't reset it by splitting bookings between platforms.

Put those pieces together and the shape of a legal San Francisco listing becomes clear. It's your primary home, registered to you personally, hosted whenever you're around and empty-rented for a capped 90 nights when you travel. Keep in mind that the city treats this as a way for residents to share the home they live in, not as a channel for turning housing into hotel stock, and every rule downstream reflects that intent.

Starting a Short-Term Rental Business in San Francisco County

So what does that leave you as an actual business? Honestly, less than most people arrive hoping for. Unfortunately for anyone reading this with an investment plan, there's no whole-home rental business to build in San Francisco, because you can only ever list the place you live in. No permit unlocks a second unit, no LLC gets you around the residency test, and the city won't register a property where you don't sleep 275 nights a year.

What you can build is real, though, so don't write it off entirely. A San Francisco host is renting their own home: a spare room while they're there, or the whole place for up to 90 nights a year while they're away. In a city with nightly rates as high as this one, even a capped un-hosted allowance plus unlimited hosted nights can add up to meaningful income, so the model to run in your head is your own residence, not a portfolio. Make sure you're modeling the right thing, because a spreadsheet built on 365 whole-home nights will be wrong here by design.

Before you spend a dollar, check that your specific unit even qualifies, since San Francisco carves out whole categories of housing:

• Below-market-rate and income-restricted units can't be short-term rented at all.
• Single-room-occupancy units, dormitories and student housing are excluded, with a narrow summer exception for some student housing.
• Accessory dwelling units and junior ADUs are out, which matters because state law also requires ADU tenancies to run longer than 30 days.
• Units subject to an Ellis Act eviction after November 1, 2014 are permanently barred.
• The Presidio, Fort Mason and Treasure Island are outside the program entirely, as are boats, RVs and other non-permanent structures.

If your home clears that list and you genuinely live there, you've got a path. Assuming the numbers still work once you've priced in the 90-night un-hosted ceiling, the next question is the paperwork, and there's a fair bit of it.

Short-Term Rental Licensing Requirements in San Francisco County

That paperwork starts with two separate certificates, and you need both before a single guest checks in. First, you register as a business with the Office of the Treasurer and Tax Collector and get a Business Registration Certificate. Then you apply to the Office of Short-Term Rentals for a Short-Term Residential Rental Certificate, which is the one that authorizes the listing. Neither alone is enough, so be aware that a business registration on its own does not let you take a booking.

The short-term rental certificate carries a non-refundable application fee of $925, and it's good for two years from the approval date. Since that fee doesn't come back if you're denied, it really pays to confirm your eligibility before you file rather than after. You'll also need to carry liability insurance of at least $500,000 covering short-term rental use, though if you host exclusively through a platform that already provides equal or greater coverage, that can satisfy the requirement.

Once you're approved, a handful of ongoing duties come with the certificate, and the city checks them:

Requirement	What it means
Registration number on every listing	Your certificate number has to appear on each Airbnb, Vrbo or other listing
275 nights of residency	You must keep living in the unit at least 275 nights per calendar year
90 un-hosted nights, cumulative	The whole-home cap runs across all platforms combined, not per platform
$500,000 liability insurance	Maintained for as long as you host
Business registration kept current	Renewed annually with the Treasurer and Tax Collector

Remember that the certificate lasts two years, not forever, so you'll renew it on that clock while your business registration renews on its own annual cycle. The two calendars don't line up, which catches people out, so it's worth diarizing both dates the day you're approved.

Required Documents for San Francisco County Short-Term Rentals

Getting that certificate approved comes down to proving you live where you say you do, so the documents all point at one thing: permanent residency. The Office of Short-Term Rentals asks you to supply at least two proofs from its approved list, and they have to show the unit you're registering.

• Motor vehicle registration at the address.
• A California driver's license or state ID showing the unit.
• Voter registration at the address.
• Your current San Francisco property tax bill, for the fiscal year in progress.
• A utility bill, though you can use only one utility bill toward the two-document minimum.

Because two of those have to come from different categories, don't plan on stacking two utility bills or a license plus an ID that shows the same thing. Pull documents that independently place you in the unit. You'll also list every platform listing tied to the rental, complete with the listing URL or ID, and you'll add your record number to those listings during the review so the city can match them to your application. Watch out here: while your application is pending, listings without that number on them can be removed and pending reservations cancelled, so get the number posted as soon as the office gives it to you.

San Francisco County Short-Term Rental Taxes

Assuming you clear the paperwork and are able to start hosting, there's still tax to deal with, and San Francisco's is thankfully simpler than the registration. The city charges a 14% Transient Occupancy Tax on the rent for any stay under 30 nights, and it's collected on top of what you charge the guest, then remitted to the Treasurer and Tax Collector.

Here's the part that saves most hosts real hassle. Airbnb is what San Francisco calls a Qualified Website Company, which means Airbnb collects and remits the full 14% TOT for you. If you host exclusively through a qualified platform, you don't file your own TOT returns and you don't need a separate Certificate of Authority. A qualified platform also collects the city's Tourism Improvement District assessment from hosts, which runs roughly 2.00% to 2.25% of gross revenue depending on the zone as of July 2026. Do check that whatever platform you use is a qualified company, because if you book guests any other way, collecting and remitting that 14% falls back on you.

Charge	Rate	Collected by
Transient Occupancy Tax	14%	Treasurer and Tax Collector (or the platform, if qualified)
Tourism Improvement District	~2.00% to 2.25%	Qualified platform, from the host
Business registration fee	$0 for a qualifying host	Treasurer and Tax Collector
California state income tax	Varies with income	Franchise Tax Board

That business registration line deserves a note, because it surprises people in a good way. If your only business is hosting, you have no payroll, and you rent a single residential structure of fewer than four units, you're a "host exempt" filer and the fee is $0. You still have to file, mind you, and the registration renews each year on a spring deadline that shifts, so don't skip it just because nothing's owed. Your rental profit is also ordinary income to the state, taxable by the Franchise Tax Board, and San Francisco has no separate host income tax beyond the TOT.

California Wide Short-Term Rental Rules

Those local taxes sit under a state framework that, for once, stays mostly out of the way. California has no statewide short-term rental permit, no state registry, and no state occupancy tax. Instead, Revenue and Taxation Code Section 7280 lets cities and counties levy their own TOT on stays of 30 days or less, which is what San Francisco's 14% is. Almost everything a host cares about is decided locally, and our California statewide guide maps how that plays out across the state.

Still, one piece is new for 2026 and worth knowing: California's Short-Term Rental Facilitator Act, SB 346, took effect January 1, 2026. Where a local government has adopted an ordinance, and San Francisco has, platforms must report each rental's physical address to the city and carry local license numbers and tax certification in their listings. In practice that formalizes at the state level what San Francisco already does through Airbnb's registration-number rules, so it tightens data-sharing rather than changing what you're allowed to do.

A few other state guardrails shape the edges. City fine caps under Government Code Section 36900 limit STR-ordinance penalties, hosting platforms must warn you that listing may violate your lease or insurance, and parts of San Francisco's western shoreline fall inside the state coastal zone, where the Coastal Commission has a say over how STR rules get adopted. None of that loosens the residency test, but it's the backdrop the city rules operate against.

Does San Francisco County Strictly Enforce STR Rules? Is San Francisco Airbnb Friendly?

Given how much state and city machinery now points at these listings, you can probably guess the answer: yes, San Francisco enforces, and it does so with more teeth than most cities. The Office of Short-Term Rentals can issue a notice of violation carrying a penalty of $484 per day, per unit, and because that's a daily figure, an un-permitted listing left up for a few weeks stops being a slap on the wrist and turns into real money fast.

The enforcement doesn't just wait for a fine, either. Platforms verify your registration number before your listing can operate, so a home that isn't registered mostly can't take bookings in the first place, which is a far harder wall than an after-the-fact inspection. On top of that, when you apply, the office notifies the property owner of record, so a renter can't quietly register a landlord's unit without the landlord finding out. If your certificate is rejected, suspended or revoked, you do get an appeal, but you have to file it in writing within 30 calendar days of the notice, so don't sit on it.

Is the city Airbnb friendly? It's friendly to residents sharing their own homes and openly hostile to everyone else, which is a fair summary of the whole regime. If you fit the resident model, the process is navigable and the tax collection is mostly automated. If you were hoping to run whole units at nightly rates, San Francisco is one of the least accommodating markets in the country, and the enforcement record backs that up.

How to Start a Short-Term Rental Business in San Francisco County

Knowing the city pushes hard, the order you do things in matters, because the early steps tell you whether the later ones are even worth your time. Here's the sequence I'd follow.

1. Confirm your unit qualifies before spending anything. Rule out BMR units, ADUs, SROs, post-2014 Ellis Act units and the excluded areas. If your home is one of those, stop here, since no fee fixes it.
2. Check you meet the residency test. You need at least 60 days of living there before you apply and a genuine plan to stay 275 nights a year. This is the requirement the city checks hardest.
3. Register as a business with the Treasurer and Tax Collector. Get your Business Registration Certificate, and if you qualify as a host-exempt filer, expect a $0 fee that you still have to file for.
4. Line up your insurance. Confirm you carry, or your platform provides, at least $500,000 in liability coverage for short-term rental use.
5. Gather two proofs of residency and apply to the Office of Short-Term Rentals. Pay the non-refundable $925, and remember it covers a two-year certificate.
6. Post your registration number on every listing as soon as the office issues it, and keep listing details matching what you told the city.
7. Track your two clocks. The STR certificate renews every two years and the business registration renews annually, so diarize both.

Work through it in that order and you rarely waste money. Jump ahead to paying the $925 before you've checked eligibility, and you can lose it on a unit that was never going to qualify.

Who to Contact in San Francisco County about Short-Term Rental Regulations and Zoning?

When a step in that sequence stalls, two offices handle almost everything between them, and knowing which one owns your question saves a lot of time. The Office of Short-Term Rentals, part of the Planning Department, handles the certificate, eligibility, listing questions and enforcement.

• Address: 49 South Van Ness Avenue, Suite 1400, San Francisco, CA 94103
• Phone: 628.652.7599
• Email: [email protected]
• Hours: Monday through Friday, roughly 8:00 a.m. to 4:00 p.m.

For anything involving money owed to the city, though, it's the Office of the Treasurer and Tax Collector that runs business registration and the Transient Occupancy Tax. Their Transient Occupancy Tax page carries the current rules on who collects, who files, and the qualified-platform relief, while their lessors of residential real estate page walks through the business registration side. When your question is about zoning or which building categories qualify, that's Planning too, since the Office of Short-Term Rentals sits inside it.

What Do Airbnb Hosts in San Francisco County on Reddit and Bigger Pockets Think about Local Regulations?

Talk to enough hosts and the contact experience above tends to split them cleanly, which mirrors what you see in public host discussion. What follows is my read of the recurring themes rather than any kind of survey, so do weigh it as sentiment, not fact.

• Investors have mostly moved on. The common advice for anyone asking about buying property to run whole-home in San Francisco is to look at less restrictive counties, because the residency rule closes off the model outright. Threads that stay local pivot to 30-plus-day furnished rentals, which sit outside this regime under ordinary landlord-tenant rules.
• Resident hosts describe a workable, if bureaucratic, process. People who actually live in their units tend to report that registration is navigable and that Airbnb handling the 14% tax removes the biggest headache. Their complaints cluster around documentation and the two-clock renewal setup rather than the rules themselves.
• The 90-night un-hosted cap draws steady grumbling. Hosts who want to travel more than three months a year while renting the empty home find the ceiling tight, and it's the number people most often ask how to stretch. The honest answer is that it's cumulative and enforced, so there's no clever workaround.
• Nobody argues enforcement is toothless anymore. With platforms checking registration before a listing can operate, the old debate about whether the city bothers is over. What hosts argue about now is whether the residency model is fair, which is a different conversation.

Take the last point seriously if you're deciding between here and a neighboring county, because enforcement in San Francisco isn't a risk you can price into a spreadsheet. It arrives as a listing that can't take a booking. For a sense of how the rules compare a short drive away, the San Mateo County guide covers the Peninsula and the Sonoma County guide covers the wine-country markets, both of which treat whole-home rentals differently than the city does. Before you choose, it's worth pulling the actual performance numbers for the California short-term rental market so you're comparing revenue, not just rules.

Frequently Asked Questions

Can you run an Airbnb in San Francisco County, California in 2026?

Yes, but only in the home you live in. San Francisco allows short-term rentals for permanent residents who register their primary residence, hold a two-year certificate, and carry the required insurance. You can host guests while present for unlimited nights and rent the place un-hosted for up to 90 nights a year. Renting a separate investment property whole is not permitted.

How much does a San Francisco short-term rental certificate cost?

The Short-Term Residential Rental Certificate carries a non-refundable application fee of $925 and lasts two years from approval. On top of that, you register as a business with the Treasurer and Tax Collector, though a host whose only activity is short-term renting, with no payroll and one small residential structure, qualifies as host-exempt and owes a $0 business registration fee while still having to file.

What is the 90-night rule in San Francisco?

San Francisco caps un-hosted short-term rentals, where you're away and the guest has the whole place, at 90 nights per calendar year. That limit is cumulative across every platform combined, so splitting bookings between Airbnb and Vrbo doesn't reset it. Hosted stays, where you're present in the unit overnight with the guest, have no annual cap, so residents who host while home can rent far more than 90 nights.

Do you pay hotel tax on a San Francisco Airbnb?

Yes. San Francisco charges a 14% Transient Occupancy Tax on stays under 30 nights, plus a Tourism Improvement District assessment of roughly 2.00% to 2.25%. If you host exclusively through a qualified platform like Airbnb, the platform collects and remits both for you, so you don't file your own returns. Book guests any other way and collecting that 14% becomes your responsibility.

Can you rent an entire house short-term in San Francisco?

Only if it's the house you live in, and only for up to 90 un-hosted nights a year. You must be the permanent resident, occupy it at least 275 nights annually, and register the unit. A second home or a property bought purely to rent whole at nightly rates can't be short-term rented in San Francisco at all, though a stay of 30 nights or longer falls outside these rules as an ordinary rental.
