Short-Term Rentals in San Francisco, CA

If you live in San Francisco or are thinking about moving there, short-term rentals are one of those things you probably won't think about until they affect you directly. San Francisco has 10 specific rules on the books covering different aspects of short-term rentals, and some of them might surprise you.

Taxes & Fees

San Francisco Short-Term Rental Hosts must file Transient Occupancy Tax and Tourism Improvement District Assessment returns annually, or have a Qualified Website Company like Airbnb remit the tax monthly on their behalf.

Key details: Filer: Short-Term Rental Host. Deadline: On or before January 31. Platform duty: Qualified Website Company remits monthly. Certificate of authority: Not required for hosts.

Failure to file or remit exposes the host to the penalties and interest set out for third-party taxes generally, collected by the Tax Collector; a host doing business outside a Qualified Website Company's platform must still file annually for that unreported portion.

Insurance Requirements

San Francisco hosts must carry at least $500,000 in liability insurance for their short-term rental, or book only through a platform that provides equal or greater coverage, to stay on the Registry.

Key details: Minimum coverage: $500,000 aggregate liability. Alternative: Equal or greater platform coverage. Must protect: Owner and building tenants. Governing section: Admin. Code § 41A.5(g)(1)(D).

Operating a Short-Term Residential Rental without the required $500,000 liability coverage, or an equivalent hosting-platform policy, breaks a condition of the Sec. 41A.5(g) exception, exposing the host to unlawful-conversion enforcement under Chapter 41A.

Primary-Residence-Only Rule

San Francisco law only lets a Permanent Resident short-term rent the home that is their actual Primary Residence -- investment properties and second homes can never be registered as short-term rentals.

Key details: Eligible unit: Only the host's Primary Residence. Investment properties: Never eligible for STR use. Proof required: 2+ documents tying address to resident. Listings per unit: Only one Permanent Resident allowed.

Offering a non-primary-residence unit -- a second home, investment condo, or a unit where the applicant isn't the true Permanent Resident -- as a Short-Term Residential Rental is an unlawful conversion subject to Chapter 41A's civil and criminal penalties.

This is not one of those rules that cities tend to ignore. San Francisco actively enforces its primary-residence-only rule requirements.

Host Platform Liability

San Francisco holds Hosting Platforms like Airbnb legally responsible for confirming a listing's Registry status, and a platform that books an unregistered unit faces civil penalties and misdemeanor criminal liability under Chapter 41A.

Key details: Platform duty: Confirm Registry status before booking. Compliance proof: Monthly signed affidavit required. Record retention: 3 years per transaction. Criminal exposure: Misdemeanor, up to 6 months jail. Civil penalty: Up to $1,000 per day.

Booking an unregistered unit without exercising reasonable care risks civil penalties up to $1,000 per day under Sec. 41A.5(d)(3), plus misdemeanor prosecution -- up to a $1,000 fine or six months in jail -- under Sec. 41A.5(e).

This is one of the stricter rules in San Francisco's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

San Francisco's Short-Term Rental law only covers stays booked for under 30 days; a 30-day-or-longer booking is an ordinary tenancy that skips Chapter 41A's registry, permit, and night-cap rules entirely.

Key details: Threshold: Stays under 30 days are regulated. 30+ day stays: Ordinary tenancy, not short-term. Governing law: Admin. Code § 41A.4. Enforcing agency: Planning Department.

No Chapter 41A violation applies to a genuine 30-day-plus rental. Splitting one long stay into shorter bookings to evade registration, or misrepresenting the term length, can still trigger the Chapter's unlawful-conversion penalties.

San Francisco is more permissive than most cities when it comes to extended home share. That said, there are still limits.

Repeat Violator Strikes

A second short-term rental violation by the same owner triggers double the fine of a first offense, plus a one-year registry ban.

Key details: First violation cap: 4x $121/hour, per unit/day. Repeat violation cap: 8x $121/hour, per unit/day. Registry removal: One year, multiple violations. Continued listing penalty: Up to $1,000/day.

Up to 8x the $121 hourly rate per day for repeat violations, plus mandatory one-year registry removal and up to $1,000/day in additional civil penalties for continued unlawful listing.

This is not one of those rules that cities tend to ignore. San Francisco actively enforces its repeat violator strikes requirements.

Short-Term Rental Parking Rules

San Francisco Administrative Code Chapter 41A does not impose dedicated parking requirements on short-term rentals, and the Planning Code does not require off-street parking specifically for STR use beyond what already applies to the underlying residential unit. STR guests parking on the street are subject to all standard SFMTA rules: posted Residential Permit Parking (RPP) time limits, street-cleaning restrictions, the 72-hour vehicle storage limit, and metered zones. RPP areas allow guests to park beyond posted limits only with a valid one-day visitor permit purchased by the host or guest.

Key details: Measurement: Chapter 41A imposes no STR-specific off-street parking requirement. Measurement: Street parking limited to 72 consecutive hours (CVC 22651(k)). Permit/License: RPP zones require permit beyond posted time limits. Permit/License: One-day visitor permits: up to 20 per address per year. Permit/License: Two-week visitor permits: up to 32 weeks per address per year.

SFMTA parking citations vary by violation type: street-cleaning violations typically run around $80-$110, expired meter or time-limit violations $90-$100, and 72-hour overtime parking results in a citation and tow. Blocking a driveway or curb cut is subject to citation and tow under the Transportation Code. Although Chapter 41A imposes no STR-specific parking penalty, repeated guest parking complaints can be considered by OSTR as part of a broader nuisance review of an STR certificate.

If you are coming from a city with tighter rules, you will find San Francisco gives residents more flexibility on short-term rental parking rules.

Occupancy Limits

San Francisco STR occupancy is governed by Housing Code maximum-occupancy rules plus Admin Code Chapter 41A. Generally 2 persons per bedroom plus 2 additional, capped by square footage, and STRs cannot exceed the dwelling unit's legal occupancy.

Key details: Measurement: Formula: 2 per bedroom + 2, capped at 1 per 200 sq. Measurement: Typical 2BR unit maxes at 6 overnight guests. Permit/License: Occupancy must be listed on OSTR registration and platform. Fees: Exceeding is $1,000/day violation under Chapter 41A. Authority: Events/parties prohibited without separate permit.

Night Caps

San Francisco caps unhosted short-term rental days indirectly: a Permanent Resident must occupy the unit at least 275 days a year, leaving at most about 90 days available for short-term rental.

Key details: Minimum occupancy: 275 days per calendar year. Partial-year alternative: 75% of days owned or rented. Effective rental cap: About 90 days per year. Compliance proof: 2 years of occupancy records kept.

Renting the unit as a Short-Term Residential Rental beyond the days left after meeting the 275-day/75% occupancy floor is an unlawful conversion, subject to Chapter 41A's civil penalties of up to $1,000 per day and possible misdemeanor prosecution.

Short-Term Rental Permits

San Francisco requires the Permanent Resident of a unit to register it on the Short-Term Residential Rental Registry for a two-year term, pay a $50 fee, and receive an individual registration number from the Planning Department before hosting short-term guests.

Key details: Registration term: 2 years, renewable. Application fee: $50 per application/renewal. Registrant: The unit's Permanent Resident. Ongoing duty: Quarterly rental-day reports. Issued by: Planning Department.

Listing a unit before the Registry assigns it an individual registration number, letting the two-year registration lapse without a completed renewal application, or failing to file the quarterly rental-day reports that keep a host in good standing is treated as an unlawful conversion enforceable under Chapter 41A.

Compared to other cities, San Francisco takes a harder line on short-term rental permits. The enforcement and penalty structure reflects that.

If you are a homeowner, renter, or business owner in San Francisco, take the time to understand these requirements before they become a problem.
