Airbnb Rules California: Laws, Regulations, and Compliance Guide

California Airbnb Compliance Checklist

• ☐ Verify Local STR Ordinance Applicability

  • Confirm whether the host's city or county has adopted a local short-term rental ordinance, since California does not operate a single statewide registration system.

  • Check with the local planning or community development department directly; ordinance databases are not always current online.

• ☐ Obtain a Local STR Permit or Registration

  • Submit a completed application to the relevant municipal agency; fee amounts vary by jurisdiction (e.g.

  • Display the permit number on every platform listing as required by local ordinance.

• ☐ Confirm Owner-Occupancy or Eligibility Status

  • Where a jurisdiction restricts STR permits to primary residences, verify the property qualifies before listing, operating without eligibility voids the permit and triggers fines.

• ☐ Register for a Transient Occupancy Tax Account

  • Register with the local finance or tax office to collect and remit Transient Occupancy Tax (TOT), which ranges from 10% to 15.5% depending on the city.

  • If Airbnb collects TOT automatically under a Voluntary Collection Agreement, confirm in writing which taxes are covered and which the host must remit independently.

• ☐ Obtain a California Seller's Permit if Required

  • Register with the California Department of Tax and Fee Administration (CDTFA) if the local jurisdiction requires hosts to collect district taxes not covered by platform agreements.

• ☐ Install Mandatory Safety Equipment

  • Install working smoke detectors in every sleeping room and hallway per California Health and Safety Code Section 13113.7.

  • Install a carbon monoxide detector on each floor per Health and Safety Code Section 17926.

  • Verify a fire extinguisher is accessible on each level of the property.

• ☐ Post Required Guest Disclosures

  • Post the local STR permit number, maximum occupancy, noise ordinance hours, and trash collection schedule in a visible location inside the unit.

• ☐ Comply with Occupancy Limits

  • Cap guest count per the local ordinance, most California cities set a limit of 2 guests per bedroom plus 2 additional guests, but verify the exact cap for the specific jurisdiction.

• ☐ Adhere to Minimum Stay Requirements Where Applicable

  • Check whether the city imposes a minimum stay (e.g., 30 nights in some coastal zones), and configure platform settings to block non-

1. Regulatory Overview

Short-term rental operators in California face compliance obligations at three distinct levels: state law, local municipal code, and, where applicable, county ordinance. No single statewide permit governs all STR activity.

Instead, California sets the outer boundaries through general statutes while cities and counties write the operational rules that hosts actually live by.

At the state level, the primary framework comes from California Civil Code Section 1940, which defines residential tenancy thresholds, and the California Transient Occupancy Tax statutes codified under Revenue and Taxation Code Sections 7280-7283.51.

These statutes do not cap night limits or restrict occupancy directly, but they establish the tax collection obligations that every local jurisdiction builds on. Assembly Bill 1731, effective January 1, 2023, further clarified platform reporting requirements for booking intermediaries operating in the state.

California law defines a short-term rental as any residential dwelling rented for a period of fewer than 30 consecutive days. Rentals of 30 days or more fall outside STR regulation and are treated as standard residential tenancies under Civil Code Section 1940.

Enforcement authority sits primarily with local agencies. Most California cities designate their Planning Department or a dedicated Short-Term Rental Office as the primary enforcing body, with code enforcement officers handling violations. The California Department of Tax and Fee Administration (CDTFA) handles state-level tax compliance separately from local permitting.

2. Airbnb License Requirements California Hosts May Need

California has no statewide short-term rental registration system. No state agency issues STR permits, and no single license number applies across jurisdictions. What governs registration is an entirely local framework; each city and county sets its own requirements, fees, and enforcement mechanisms.

Hosts operating under the assumption that one permit covers the state will face fines at the municipal level.

Local Registration Regimes

Thinking of listing your California property? Don't even think about accepting a booking without registration. The rules are a chaotic patchwork across the state's 80+ cities with STR ordinances, and what works in one town is illegal in the next.

It’s a bureaucratic maze, frankly. These three examples show just how wild the differences can be:

San Francisco Office of Short-Term Rentals: Hosts must hold a valid registration number, effective under the Residential Unit Conversion and Demolition Ordinance (Administrative Code Chapter 41A). Annual registration costs $450. Platforms are prohibited from processing transactions for unregistered listings.

Los Angeles Home-Sharing Program: In LA, you'll register through the Department of City Planning for the Los Angeles Home-Sharing Program. It’s a pretty reasonable $89 per year, but there’s a huge catch.

The program is only for a primary residence, meaning your listing must display your 8-digit registration number to prove it. Got an investment property you were hoping to rent out? Forget about it, the municipal code flat-out doesn't permit it.

Palm Springs STR Permit Program: The Palm Springs STR Permit Program really makes you work for it. You don't just need one permit; you need a Short-Term Rental Permit and a separate Business License before you can even think about listing. Get ready to open your wallet.

The combined first-year fees for a typical home can easily top $957. Palm Springs also strictly enforces a primary-residence requirement in many of its residential zones.

The primary-residence rule in Los Angeles is the most operationally significant restriction in California's municipal STR rules; it effectively prohibits whole-home investment rentals within city limits.

Hosts managing properties across multiple California cities must verify each municipality's active registration portal, as fee structures and application requirements changed in several jurisdictions between 2024 and 2026.

3. How to Check STR Rules in California Before Listing a Property

California does not maintain a statewide prohibited buildings list or formal property classification system for short-term rentals. There is no equivalent to New York's Class A/Class B multiple dwelling framework.

Eligibility is determined at the local level, governed by municipal zoning codes, HOA governing documents, and, for condominiums, individual CC&Rs (Covenants, Conditions, and Restrictions).

Local Zoning Ordinances

Your property's zoning is everything. It's the first thing you need to check. While many California cities allow STRs in typical residential zoning districts (like R-1 through R-3), some jurisdictions have put up a giant stop sign for investors.

In Santa Monica, for example, their stringent Home-Sharing Ordinance requires the host to be physically present throughout the guest’s entire stay, effectively banning all non-hosted STRs. The bottom line: check the local planning department’s map before you do anything else.

• Zoning Lookup: Contact the city or county planning department directly, or use the jurisdiction's online parcel viewer to confirm STR-permissible zoning.

• Use Classification: Some cities prohibit STRs in multi-family buildings even within permitted zones. The building type, single-family, duplex, or apartment, affects eligibility independently of the zoning district.

HOA and Cc&r Restrictions

California Civil Code does not preempt HOA rules on short-term rentals. (Assembly Bill 3182, effective January 1, 2021, restricts HOA rental prohibitions only for rentals of 31 days or longer; it does not protect STRs.)

An HOA board may lawfully ban rentals under 30 days through its CC&Rs or board resolutions, and those restrictions operate independently of any municipal permit a host might obtain.

• CC&R Review: Hosts must review the full CC&R document and any recorded amendments, not just the summary provided at purchase.

• Board Resolutions: Restrictions added by board resolution after the original CC&Rs were

4. Common Airbnb Restrictions in California That Lead to Fines

Most violations don't come from ignoring registration requirements; they come from day-to-day operations that conflict with local ordinances that hosts never read carefully. California sets no single statewide operating rulebook; each city writes its own.

• The restrictions below represent the categories most commonly cited in enforcement actions across Los Angeles, San Francisco, San Diego, and Palm Springs.

  Guest Count Limits

  Most California municipalities cap occupancy at two guests per bedroom plus two additional guests. Los Angeles Municipal Code Section 12.22 A.33 caps total occupancy at the lesser of that formula or the property's posted occupancy limit.

Exceeding the posted guest count is one of the most frequently cited violations and carries fines starting at $500 per occurrence in Los Angeles.

San Francisco's Administrative Code Chapter 41A applies a similar formula but adds a hard cap: no more than six guests regardless of bedroom count for most residential unit types.

Minimum-Stay Thresholds

30-night minimum stays apply to non-hosted listings in San Francisco under Administrative Code Chapter 41A, effective February 1, 2015. Palm Springs enforces a two-night minimum under Municipal Code Section 5.25. Santa Monica prohibits unhosted STRs entirely under Ordinance No. 2535 (effective June 20, 2015), making any unhosted listing under 30 nights an illegal rental.

Note: AB 1017 (2025 session) proposed a statewide 30-day minimum for non-owner-occupied STRs. The bill did not pass, but similar legislation is expected in the 2026 session.

Host Presence Requirements

San Francisco requires the host to occupy the unit as a primary residence for at least 275 nights per calendar year under Administrative Code Chapter 41A. Hosted-only classification means the host must be physically present during guest stays for listings under 30 nights. Violations carry fines up to $1,000 per day under San Francisco Police Code Section 790.

5. Tax Obligations

State Taxes

California imposes a statewide sales and use tax administered by the California Department of Tax and Fee Administration (CDTFA) under Revenue and Taxation Code Section 6012. Short-term rental income is subject to Transient Occupancy Tax (TOT) at the local level, not at the state level directly, but hosts must also account for state income tax on net rental income under Revenue and Taxation Code Section 17041.

Local Transient Occupancy Tax

TOT rates vary by municipality and are set by local ordinance. Los Angeles charges 14% TOT under Los Angeles Municipal Code Section 21.7.2. San Francisco charges 14% under San Francisco Business and Tax Regulations Code Article 7. San Diego charges 10.5% under San Diego Municipal Code Section 35.0102.

Hosts operating across multiple cities must track each jurisdiction's rate independently; there is no statewide TOT rate that overrides local ordinances.

Total Combined Tax Rate (Los Angeles example): 14% TOT + applicable state income tax bracket.

Platform Collection Requirements

Airbnb collects and remits TOT directly to participating California jurisdictions under voluntary collection agreements. As of January 1, 2023, Airbnb remits TOT on behalf of hosts in Los Angeles, San Francisco, San Diego, and over 150 additional California municipalities. Hosts must confirm their specific city is covered, Airbnb publishes a jurisdiction list, and gaps in coverage shift remittance responsibility to the host.

Tax Filing Requirements

Even where platforms remit TOT, hosts remain responsible for reporting STR income on the California Form

6. Safety Equipment and Building Compliance for California Strs

Mandatory Safety Equipment

• Smoke Detectors: Required in every sleeping room, outside each sleeping area, and on every level of the dwelling under California Health and Safety Code Section 13113.7, effective January 1, 2014.

• Carbon Monoxide Detectors: Required in all dwelling units with an attached garage or fossil-fuel-burning appliance under California Health and Safety Code Section 17926, effective July 1, 2011.

• Fire Extinguisher: Minimum 2A:10B:C rated extinguisher required in rental units per California Fire Code Section 906.

• Emergency Egress: Each sleeping room must have at least one openable window or door meeting California Building Code Section 1031 egress dimensions.

Building Compliance

• Electrical Systems: No exposed wiring, non-functional outlets, or overloaded panels; inspected under California Electrical Code Title 24, Part 3.

• Structural Habitability: The unit must meet California Civil Code Section 1941.1 habitability standards, including weatherproofing and functioning plumbing.

• Pool and Spa Barriers: Properties with pools must comply with California Health and Safety Code Section 115922, requiring compliant enclosures and self-latching gates.

7. Booking Platform Requirements

California has no statewide law requiring platforms to verify host registration numbers or submit transaction reports to a state agency. Platform obligations are set municipally.

Verification Requirements

• San Francisco: Under Administrative Code Chapter 41A, platforms must confirm a host holds a valid registration number issued by the Office of Short-Term Rentals (OSTR) before processing transactions.

• Los Angeles: Under the Home-Sharing Ordinance (LAMC Section 151.02 et seq.), platforms must remove listings lacking a valid registration number issued by the Los Angeles Department of City Planning (DCP).

Reporting Requirements

• San Francisco: Platforms must submit monthly transaction reports to the OSTR identifying host registration numbers, listing addresses, and nights booked.

• Los Angeles: Platforms must provide transaction data to the DCP upon request, with non-compliance resulting in fines up to $2,500 per violation per day.

Hosts in other California cities should verify whether their municipality has adopted comparable platform-facing mandates.

California doesn't have a statewide law that makes it illegal to advertise a short-term rental before a booking transaction occurs.

Advertising restrictions in California are applied at the municipal level; cities like San Francisco, Los Angeles, and Santa Monica enforce permit display requirements within listings, but those rules govern what a posted advertisement must contain, not whether advertising itself is prohibited.

No California statute creates a pre-transaction advertising ban that triggers penalties independently of the underlying permit violation.

Hosts operating under California's short-term rental regulation framework are subject to local ordinances on listing content, but those requirements are covered under the permit and platform compliance sections of this reference.

8. Enforcement and Penalties

Civil Penalties

California does not operate a statewide STR agency. Instead, cities and counties establish and enforce their own rules and penalties through local municipal codes.

Enforcement can be strict, with fines for unpermitted rentals varying significantly by jurisdiction. The figures below illustrate how local penalty structures differ across the state.

• Operating without registration: Up to $5,000 per violation per day in cities such as Los Angeles (Los Angeles Municipal Code Section 151.02) and San Francisco (Administrative Code Section 41A.5).

• Exceeding nightcaps or occupancy limits: $1,000–$2,500 per violation in most jurisdictions with active enforcement programs.

• Failure to collect or remit Transient Occupancy Tax: Back taxes plus penalties of up to 25% of unpaid amounts, plus interest, under California Revenue and Taxation Code Section 7280.

• Advertising an unlicensed unit: $250–$1,000 per listing per day in jurisdictions that have adopted platform-accountability ordinances.

Enforcement Mechanisms

• Platform data verification: Cities including San Francisco and Los Angeles require Airbnb and Vrbo to cross-check listing registration numbers and remove non-compliant listings within 10 business days of notice.

• Complaint-driven inspections: Neighbor complaints routed through 311 systems trigger code enforcement visits in most California cities.

• Proactive monitoring: Third-party scraping tools (used by the Los Angeles Housing Department and San Diego Development Services) flag active listings against the registered host database.

• Administrative citations: Issued without a court order under California Government Code Section 53069.4, allowing cities to fine hosts directly.

Registration Denial and Revocation

Local agencies may deny or revoke a registration on the following grounds:

• Prior violations: Documented code enforcement history at the subject property.

• Misrepresentation: False statements on the registration application.

• Unpaid fines or taxes: Outstanding balances owed to the city or county.

Zoning ineligibility: Property located in a district where STRs

9. Special Considerations

Rent-Controlled and Rent-Stabilized Units

California's Tenant Protection Act of 2019 (AB 1482), effective January 1, 2020, applies just cause eviction protections to most residential tenancies statewide.

Short-term rental activity in a rent-controlled unit creates significant legal exposure: a landlord who removes a tenant to operate an STR may face wrongful eviction liability under local ordinances, particularly in cities like San Francisco, Los Angeles, and Oakland, which maintain independent rent stabilization programs with stricter removal rules than AB 1482.

Converting a rent-stabilized unit to short-term rental use without complying with local Ellis Act or owner-move-in procedures is a violation that can result in penalties exceeding $10,000 per unit in San Francisco under Administrative Code Section 37.9.

• Lease Conflicts: Most residential leases in rent-controlled buildings prohibit subletting without written landlord consent; STR activity without that consent constitutes a material breach.

• Zoning Overlays: Some cities restrict STR permits to owner-occupied units, which automatically excludes tenant-operated listings in rent-controlled stock.

Accessory Dwelling Units (ADUs)

ADU construction in California expanded under AB 68 (2020) and AB 2221 (effective January 1, 2023), but several cities have moved to restrict STR permits in ADUs specifically.

Los Angeles prohibits short-term rentals in ADUs that are not the host's primary residence. Hosts operating ADU listings must verify local primary residence rules independently, since state ADU law does not preempt municipal STR licensing restrictions.

• Primary Residence Requirement: Many jurisdictions require the ADU or the primary structure on the parcel to serve as the host's principal residence.

• Permit Conflicts: ADUs permitted under a condition restricting occupancy to long-term tenants cannot legally convert to STR use without a zoning variance.

10. Exemptions

Not all short-term occupancies in California fall under local STR registration frameworks; several categories operate under separate regulatory regimes or are excluded by statute.

• Stays of 30 consecutive days or more: These are classified as standard residential tenancies under California Civil Code and are governed by landlord-tenant law, not STR ordinances.

• Licensed hotels and motels: Properties holding a valid Transient Occupancy Certificate under California Health and Safety Code Section 17000 et seq. operate under a distinct licensing structure and are not subject to Airbnb-specific local registration rules.

• Bed-and-breakfast establishments: B&Bs licensed under local conditional use permits typically fall outside short-term rental registration requirements, though transient occupancy tax obligations still apply.

• Student housing and dormitories: Facilities operated by accredited educational institutions are exempt from local STR restrictions under most municipal codes.

11. Legislative Developments

AB 1731 (2025): Statewide STR Registry Proposal

Introduced in the 2025 California legislative session, AB 1731 would have established a mandatory statewide short-term rental registry administered by the California Department of Consumer Affairs. Key provisions included:

• Uniform Registration Number: A single state-issued identifier required on all platform listings, supplementing (not replacing) local permits.

• Platform Reporting Mandate: Booking platforms are required to transmit quarterly occupancy and revenue data to the state.

• Non-Compliant Listing Removal: Platforms are required to delist properties lacking a valid state registry number within 30 days of notification.

AB 1731 failed to advance out of the Assembly Housing Committee and was not enacted as of June 2026.

Recent Enacted Activity

The most recent material change to California's short-term rental regulatory framework at the state level was AB 537, effective January 1, 2025, which clarified that local jurisdictions retain full authority to ban, cap, or condition STR permits without state preemption. No statewide STR licensing law is currently in force.
