Airbnb rules in San Francisco: A clear 2026 compliance guide for hosts
San Francisco has one of the most valuable short-term rental markets in the United States. High tourism demand, strong nightly rates, and year-round travel mean a well-managed listing can generate significant revenue. But the city also has some of the strictest short-term rental regulations in the country.
San Francisco only allows Airbnb hosting under a primary-residence model, meaning most investors cannot legally run multiple short-term rental properties. Hosts must meet residency requirements, register their business and listing with the city, track unhosted nights, and comply with tax and reporting obligations.
If you’re planning to list your home on Airbnb in San Francisco, understanding these rules is essential. This 2026 compliance guide explains how Airbnb rules in San Francisco work and what hosts must do to operate legally.
If you manage multiple listings or want to streamline compliance and guest operations, platforms like Hostaway can help automate reporting, communication, and workflow management across properties.

Business registration and short-term rental certification
Hosted vs. unhosted rental limits
Property eligibility and prohibited housing types
Insurance and tax obligations

Who this guide is for
This guide is designed for:
San Francisco homeowners considering listing on Airbnb
Tenants exploring legal hosting options
Hosts renting out spare rooms or their full home occasionally
Property managers advising clients on compliance
Real estate investors researching the San Francisco STR regulatory environment
Why this matters
San Francisco’s short-term rental laws are built around a single goal: protecting long-term housing supply.
Because of this policy objective, the city has adopted strict limits on who can host and how often entire homes can be rented. Unlike many tourist cities, San Francisco does not allow widespread investor-owned Airbnb portfolios.
The city actively enforces these rules through registration checks, reporting requirements, and coordination with booking platforms. Hosts who misunderstand the rules often discover too late that their property is ineligible.
Understanding the legal framework before listing a property can prevent costly compliance mistakes.

Understanding San Francisco’s short-term rental legal framework
San Francisco regulates Airbnb and similar platforms through the Short-Term Residential Rental Ordinance, administered by the city’s Office of Short-Term Rentals (OSTR).
A short-term rental is defined as the rental of all or part of a residential unit for fewer than 30 consecutive nights. These regulations apply to all booking platforms and direct bookings.
The system is designed around several key principles:
Short-term rentals must occur in a primary residence
Hosts must register with the city
Entire-home rentals are limited
Platforms must verify registration before accepting bookings
Hosts must report rental activity and pay local taxes
Who can legally operate an Airbnb in San Francisco
Before applying for registration, hosts must meet several eligibility requirements related to residency status, property type, and housing regulations. Understanding these conditions is the first step to determining whether your property qualifies for legal Airbnb hosting in San Francisco.
Permanent resident requirement
San Francisco only allows short-term rentals in the host’s primary residence. To qualify as a permanent resident, a host must:
Live in the unit at least 275 nights per year
Have lived in the property for at least 60 days before applying
Be either the owner or tenant of the dwelling
This requirement prevents hosts from purchasing multiple properties solely for short-term rental.
Owner and tenant eligibility
Both owners and tenants can legally host, but tenants must also follow any private agreements that apply to the property. City approval does not override private contractual restrictions like lease agreements, HOA, or condominium rules, and tenancy-in-common agreements.
One-unit rule
Even if someone owns or rents multiple units in a building, only the unit where they live can be registered for short-term rentals. This effectively prevents multi-unit Airbnb operations within the city.
Registration requirements and application process
Operating a short-term rental in San Francisco requires two separate registrations.
Step 1: Business registration
Hosts must first register their activity as a business with the San Francisco Treasurer & Tax Collector.
This process creates a Business Account Number (BAN), which identifies the host for tax purposes. Any income from short-term rentals is treated as business activity.
Step 2: Short-term rental certification
After registering the business, hosts must apply for certification with the Office of Short-Term Rentals. The application requires documentation confirming eligibility.
Typical documentation includes:
Business Registration Certificate
Proof of permanent residency
Property-liability insurance documentation (if required)
Application form and fee
Proof of residency:
Applicants must submit two documents proving their residency, such as:
Driver’s license
Vehicle registration
Voter registration
Property tax exemption documentation
Utility bill
Application fee
The city charges a $925 non-refundable application fee. If approved, the short-term rental certificate is valid for two years.
Listing registration numbers
Listings must display a valid registration number. Two formats exist:
Pending application number. Example: 2023-123456STR
Approved certificate number. Example: STR-0001234
Listings without valid numbers can be removed from hosting platforms.
Hosted vs. unhosted rentals
San Francisco distinguishes between two types of short-term rentals.
Hosted stays
A hosted stay occurs when the host remains in the home overnight during the guest’s stay. Important points:
Host must be physically present in the unit
Host and guest share the residence
No annual limit applies
Hosted stays typically involve renting out a spare bedroom.
Unhosted stays
An unhosted stay occurs when the host is not present overnight. Examples include renting out the entire apartment while traveling. These rentals are limited to 90 nights per calendar year.
Hosts who offer both types of rentals must create separate listings for each.
Property eligibility and ineligible units
Not every housing unit in San Francisco can legally operate as a short-term rental. The property must be:
Permitted for residential use
Free of unresolved housing or planning code violations
Located outside restricted housing programs
Ineligible property types
The following housing types generally cannot be used for Airbnb:
Below-Market-Rate housing
Public housing
Dormitories
Single-Room-Occupancy buildings
Accessory Dwelling Units (ADUs)
Junior ADUs
Properties affected by Ellis Act evictions after 2014
Units in Treasure Island, Fort Mason, or the Presidio
Short-term rentals are also prohibited in many non-traditional living spaces such as:
RVs or vans
Boats or watercraft
Treehouses or outdoor sleeping areas
Commercial or industrial buildings
These restrictions ensure that short-term rentals do not reduce affordable housing availability.
Rules for multi-unit buildings
San Francisco places additional restrictions on multi-unit properties.
Key rules include:
Only the unit where the host lives may be registered
Other units in the building cannot be used for short-term rentals
Private building agreements may impose additional restrictions
Hosts must also comply with:
HOA rules
Condominium bylaws
Lease agreements
CC&Rs (Covenants, Conditions, and Restrictions)
Failure to follow these private rules may lead to disputes even if the listing is legally registered with the city.
Insurance requirements
San Francisco requires hosts to maintain property liability insurance of at least $500,000. This coverage protects against injuries or damages involving guests.
Some hosting platforms provide liability coverage automatically. If a host uses only those platforms, separate insurance documentation may not always be required during registration.
However, many experienced hosts still purchase independent short-term rental insurance to cover:
Property damage
Liability outside platform bookings
Taxes and financial obligations
Short-term rental hosts in San Francisco must comply with two types of tax obligations.
Transient Occupancy Tax (TOT)
Guests staying fewer than 30 nights must pay the 14% Transient Occupancy Tax.
Hosts must:
Register for a Certificate of Authority
Collect the tax from guests
Remit the tax to the city
Business personal property tax
Hosts must also report furnishings and equipment used in the rental business. Items commonly included:
Appliances
Electronics
Decorative items used in the rental space
These items are reported annually through the Assessor-Recorder’s Office.
Operational rules and ongoing compliance
After receiving certification, hosts must maintain several ongoing compliance obligations.
Quarterly reporting
Certified hosts must submit quarterly rental activity reports to the Office of Short-Term Rentals.
Reports typically include:
Dates of short-term stays
Number of bookings
Confirmation of residency requirements
Recordkeeping
Hosts must maintain documentation showing:
Primary residence status
Days occupied by the host
Dates of short-term rentals
These records may be requested during compliance checks.
Safety and building requirements
Properties must remain compliant with:
Fire safety regulations
Building codes
Accessibility rules where applicable
Hosts may also be required to post emergency and safety information inside the unit.

Common challenges and solutions
San Francisco’s short-term rental framework is detailed, but many hosts run into compliance problems simply because they misunderstand how certain rules work in practice. Issues often arise around residency requirements, reporting deadlines, and property eligibility. The following challenges are some of the most common situations hosts encounter, along with practical ways to address them before they become compliance risks.
Challenge 1: Misunderstanding the 90-day rule
Solution: Track unhosted nights carefully throughout the year and keep clear records of each booking. If you plan to offer both hosted and unhosted stays, create separate listings and monitor your booking calendar to avoid exceeding the annual cap.
Challenge 2: Listing an ineligible unit
Solution: Before starting the application process, confirm that the property is eligible under the city’s short-term rental rules. Checking property records, planning classifications, or speaking with the Office of Short-Term Rentals can help avoid submitting an application for a unit that cannot legally be approved.
Challenge 3: Missing reporting deadlines
Solution: Set up a simple compliance calendar that includes quarterly reporting deadlines, business registration renewals, and tax filing dates. Many hosts also use property management or automation tools to track reporting requirements and avoid missed submissions.
Challenge 4: Ignoring private building rules
Solution: Review any private agreements tied to the property before applying for short-term rental registration. If you are a tenant, confirm whether your lease allows subletting or short-term rentals, and seek written permission from the property owner when necessary.
Penalties and enforcement actions
San Francisco actively enforces its short-term rental regulations through the Office of Short-Term Rentals. Hosts who fail to follow the rules can face penalties, listing removals, or suspension of their short-term rental certificate.
Penalties may include:
Daily fines starting around $484 per unit
Listing removal from booking platforms
Suspension or revocation of STR certificates
Referral to the City Attorney for civil or criminal action
Hosts must stop short-term rental activity immediately if their application is denied or their certificate is revoked.
Conclusion and next steps
San Francisco remains a valuable market for short-term rentals, but only under a tightly regulated system. The city’s framework favors primary-residence hosts renting spare rooms or occasionally renting their full home while away.
Before listing a property, hosts should:
Confirm the unit is eligible
Verify it is their primary residence
Register the hosting business
Apply for STR certification
Understand the 90-night limit
Set up tax and reporting systems
With proper compliance and careful recordkeeping, hosting in San Francisco can remain both legal and profitable.
FAQs
Could San Francisco ever remove the 90-night cap on unhosted rentals?
While possible, it would require significant policy changes because the cap exists to protect the long-term housing supply. Any expansion of STR rights would likely involve citywide debates over housing and new legislation.
Why do some San Francisco listings stay active even if the rules are strict?
Some listings operate under hosted-stay rules, while others may be long-term rentals or intermediate-length stays that fall outside STR regulations. In other cases, enforcement actions may take time to resolve.
How do short-term rental rules affect property values in San Francisco?
In markets where STR investment is restricted, property values tend to reflect traditional housing demand rather than tourism-driven income potential. This can reduce speculative investment pressure but also limit STR-focused real estate strategies.
Do strict Airbnb rules reduce tourism in San Francisco?
Tourism generally continues through hotels, licensed STRs, and traditional accommodations. Regulations mainly affect the number of entire homes available on short-term rental platforms rather than visitor demand overall.
Are San Francisco’s Airbnb rules considered strict compared to other cities?
Yes. Many US cities allow multiple STR units or investor-owned rentals. San Francisco’s primary-residence model and 90-night cap make it one of the most restrictive large markets in the country.
