Short-Term Rentals in San Francisco, CA: What Residents Actually Need to Know

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 12 specific rules on the books covering different aspects of short-term rentals, and some of them might surprise you.

Insurance Requirements

San Francisco Admin Code Chapter 41A requires short-term rental hosts to carry at least $500,000 in liability insurance or to rent exclusively through a platform (Airbnb, VRBO) that provides equivalent host-protection coverage.

Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact [San Francisco code enforcement](https://codelibrary.amlegal.com/codes/san_francisco/latest/sf_administrative/0-0-0-11331) directly for current fines, enforcement procedures, and hearing options.

Compared to other cities, San Francisco takes a harder line on insurance requirements. The enforcement and penalty structure reflects that.

Primary-Residence-Only Rule

San Francisco bars short-term rentals unless the unit is the host's primary residence. Hosts must occupy the home at least 275 nights per year and register with the Office of Short-Term Rentals before listing on Airbnb, Vrbo, or any platform.

Key details: Code section: Police Code 41A.5. Occupancy minimum: 275 nights per year. Enacted: Ordinance 218-14 (2014). Enforcement agency: Office of Short-Term Rentals. Daily fine: $484 per violation day.

Listing a non-primary residence triggers $484 daily fines, removal from platforms, and Treasurer's Office tax assessments for unpaid Transient Occupancy Tax.

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

Host Presence Rule

San Francisco distinguishes hosted stays (host present overnight) from unhosted stays (host absent). Unhosted rentals are capped at 90 nights yearly while hosted stays have no annual cap, encouraging genuine home sharing over de facto hotels.

Key details: Unhosted cap: 90 nights per year. Hosted cap: No annual limit. Code section: Police Code 41A.5(g). Reporting frequency: Quarterly host reports.

Going over 90 unhosted nights triggers registration revocation, a one-year reapplication ban, $484 daily fines, and tax reassessment.

This is not one of those rules that cities tend to ignore. San Francisco actively enforces its host presence rule requirements.

Host Platform Liability

Airbnb, Vrbo, and any STR platform operating in San Francisco must verify each listing has a valid OSTR registration number before processing bookings. Platforms face direct fines for hosting unregistered listings, shifting enforcement burden from individual hosts.

Key details: Code section: Police Code 41A.5(g)(4). Per-booking platform fine: $1,000. Settlement year: 2016 federal Airbnb deal. Reporting cadence: Monthly platform reports.

Platforms face $1,000 per booking penalties, civil injunctions from the City Attorney, and potential operating bans for failing verification or reporting duties.

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.

Repeat Violator Strikes

Hosts cited three times within five years for Section 41A violations face permanent revocation of their STR registration and a lifetime ban from re-registering at any San Francisco address, alongside escalating fines on each strike.

Key details: Strike window: Five years rolling. Third-strike outcome: Permanent registration ban. Per-strike fine: $1,500. Appeal window: 30 days to Planning Commission.

Three confirmed violations in five years end STR rights permanently, add $1,500 per-strike fines, and may trigger City Attorney civil suits for unjust enrichment.

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

Night Caps

San Francisco Admin Code Chapter 41A caps un-hosted (whole-unit) short-term rentals at 90 nights per calendar year. Hosted rentals with the permanent resident present have no night cap. Registration with the Office of Short-Term Rentals is mandatory.

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.

Taxes & Fees

San Francisco imposes a 14% Transient Occupancy Tax (TOT) on rental of accommodations for stays of fewer than 30 nights, collected from guests by the host or platform. Tourism Improvement District (TID) assessments add 2.25% (Zone 1) or 2.00% (Zone 2) on gross room revenue. STR registration with the Office of Short-Term Rentals (OSTR) requires a $250 fee (valid two years), and hosts must also obtain a Business Registration Certificate from the Treasurer & Tax Collector. Hosts using Qualified Website Companies (Airbnb, misterb&b, Interval International) have TOT collected and remitted on their behalf.

Key details: undefined: undefined. undefined: undefined. undefined: undefined. undefined: undefined. undefined: undefined.

Failure to remit TOT can result in tax assessments, penalties, and interest by the Treasurer & Tax Collector. Operating without OSTR registration triggers a fine of up to $484 per day per listing under Chapter 41A. Failure to renew the OSTR certificate or file required quarterly reports can lead to certificate suspension or revocation.

Noise Rules

Short-term rental guests in San Francisco must comply with the citywide noise ordinance under Police Code Article 29. Residential noise from amplified sound, voices, or activity may not exceed 5 dBA above ambient at the nearest property line, with a 45 dBA interior limit during the 10 p.m.-7 a.m. quiet period. STR hosts are responsible under Administrative Code Chapter 41A for guest conduct and must respond to neighbor complaints. A persistent pattern of nuisance noise can lead to OSTR enforcement and certificate revocation.

Key details: undefined: undefined. undefined: undefined. undefined: undefined. undefined: undefined. undefined: undefined.

Police Code Article 29 violations are infractions or misdemeanors and may carry fines starting around $500 per occurrence under San Francisco's general nuisance penalty schedule. Repeat or persistent STR noise nuisance can trigger OSTR investigation, with administrative penalties up to $484 per day under Chapter 41A and possible suspension or revocation of the host's STR certificate. Civil nuisance claims by neighbors are also possible.

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: undefined: undefined. undefined: undefined. undefined: undefined. undefined: undefined. undefined: undefined.

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.

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.

Permit Requirements

San Francisco Administrative Code Chapter 41A requires all STR hosts to register with the Office of Short-Term Rentals (OSTR) and obtain a Business Registration Certificate from the Treasurer & Tax Collector. Primary residence only; host must occupy the unit at least 275 days per year. ADUs, BMR units, SROs, and dormitories are ineligible. Registration fee is $250 and certificates are valid for two years.

Key details: Registration: OSTR + Business Registration. Primary Residence: Min. 275 nights/year. Fee: $250; valid 2 years. Insurance: $500K liability required.

Operating without registration: $484/day per listing. Platform violations: $1,000/listing/day.
