California Short-Term Rental Laws: 2026 Guide for Hosts and Investors

California's short-term rental landscape in 2026 remains fragmented and increasingly restrictive—but with notable exceptions for savvy investors. While no statewide licensing system exists, cities and counties have built their own frameworks, and a major shift occurred at the start of this year: SB 346 now compels platforms like Airbnb and VRBO to share detailed host data with local governments, fundamentally changing how cities enforce their STR ordinances.

Whether you're a host managing a single primary residence or an investor evaluating California markets, understanding your city's specific rules—and the new data-sharing landscape—is essential. This guide breaks down the laws in California's largest and most investor-friendly STR markets, so you can make informed decisions about where to operate and how to stay compliant.

California Has No Statewide STR License—Regulation Is Entirely Local

This is the first rule of California STRs: there is no state-level short-term rental license or registration. Instead, every city and county sets its own rules. That means a property legal in Palm Springs might be completely prohibited in San Francisco, and Los Angeles has its own separate system entirely.

California does collect Transient Occupancy Tax (TOT) at the local level, ranging from 8% to 14% across cities, and platforms have been required to collect and remit TOT on behalf of hosts since 2019. But TOT is a tax, not a licensing framework. Your obligations depend entirely on where your property sits on the map.

SB 346 (Effective January 1, 2026): The Platform Data-Sharing Mandate

In early 2026, California STR enforcement entered a new era. SB 346, signed by Governor Newsom, mandates that Airbnb, VRBO, and other booking platforms must share specific host data with cities and counties. This includes host name, address, number of nights booked per year, and registration status.

For compliant hosts, this changes little. But for hosts operating illegally—running unregistered investment properties in primary-residence-only markets, exceeding night caps, or operating in restricted zones—this shift is game-changing. Cities like Los Angeles and San Francisco have already begun using SB 346 data requests to identify and remove non-compliant listings at scale. If you're considering operating in California's major urban markets, compliance is no longer optional; it's enforced.

Los Angeles: Primary Residence, 120-Night Cap, and Active Enforcement

Los Angeles Home Sharing Ordinance is one of the strictest frameworks in the country. Key rules:

• Primary residence only: You must live in the property at least 90 days per year. Investment properties and secondary homes cannot be listed as unhosted STRs.
• 120-night annual cap (unhosted): If the host is absent, rentals are capped at 120 nights per year. Hosted rentals (host present during guest stay) have no cap.
• Registration required: $89 one-time fee with the Los Angeles Department of Building and Safety (LADBS); $20 annual renewal.
• Enforcement is active: The LA City Attorney's office has aggressively removed non-compliant listings using SB 346 data since 2025. Expect continued enforcement in 2026.

Currently, roughly 20,000+ properties are registered with the city—a heavily filtered pool from the much larger number that existed before the ordinance took effect. If you own property in LA and want to operate an STR legally, primary-residence status and the 120-night cap are non-negotiable.

San Francisco: Permanent Residency, 90-Night Cap, and Quarterly Reporting

San Francisco's Host Registration Program is designed for owner-occupants only. The framework:

• Permanent resident requirement: You must be a permanent resident of the property, not just present 90 days/year like LA.
• 90-night annual limit (unhosted): Rentals of your primary residence are capped at 90 nights per year if the host is not present.
• Registration fee: $250 one-time registration with the SF Office of Short-Term Rentals.
• Platform reporting (SB 346): As of 2026, platforms file quarterly reports with the city showing all SF listings, nights booked per year, and host registration status. This ensures platforms catch illegal listings quickly.

Approximately 1,800 to 2,200 STR hosts are registered in San Francisco as of 2026—an extremely tight market with strict enforcement. Investment properties are essentially shut out of the market unless you live in the unit full-time.

San Diego: Tiered Licensing with a Competitive Lottery for Tier 3 (Investment Properties)

San Diego offers a more flexible framework through its tiered STR licensing system, though Tier 3 availability remains extremely limited:

• Tier 1 (Home Share, Host Present): $75/year, no night limit. The host must be present during the guest stay. Easiest category to obtain.
• Tier 2 (Whole Home, Primary Residence, Host Absent): $100/year, no night limit. The property must be your primary residence, but you don't have to be present.
• Tier 3 (Whole Home, Non-Primary): $100/year, but limited by neighborhood lottery system. Capped at 2% of total housing units per neighborhood; most neighborhoods have years-long waitlists as of 2026.

San Diego's Tier 3 lottery system, launched January 1, 2023, remains extremely competitive. If your investment property is in a popular beach or downtown neighborhood, securing a Tier 3 license can take years. However, if you own a primary residence or are willing to be host-present for Tier 1, San Diego offers significantly more flexibility than LA or SF.

Palm Springs: The Most STR-Friendly Major California Market

If you're seeking a California market that welcomes investment-property STRs, Palm Springs is the exception to the rule. The city's framework:

• STR permit required: $100/year. No primary residency requirement, making investment properties fully legal.
• No 30-day minimum: Unlike many California cities, Palm Springs permits short stays. You can list for nightly bookings.
• Permit display: Your city STR permit number must be displayed in all listing advertisements. Platforms require this before activating a listing.

Palm Springs remains one of the most investor-friendly STR markets in California. Combined with strong seasonal demand (especially November through April), it attracts buy-to-rent investors who would be shut out of LA, SF, or coastal markets entirely.

Coastal Markets and Desert Markets: A Tale of Two Californias

California's STR landscape splits sharply along geography. Coastal markets—Santa Barbara, Carmel, Big Sur—are extremely restrictive, with most STRs prohibited entirely in Coastal Commission jurisdictions. Conversely, desert and resort markets (Palm Springs, Palm Desert, Indio, Big Bear) allow investment-property STRs with minimal barriers. If you're evaluating California markets, geography often determines regulatory friendliness more than anything else.

California-Wide Considerations: HOAs, TOT, and Compliance Trends

HOA Restrictions: Even if your city permits STRs, check your property's HOA bylaws. Many California HOAs have explicit prohibitions on short-term rentals. An HOA restriction is enforceable and will supersede city permission. Read your CC&Rs carefully.

Transient Occupancy Tax: Regardless of city, California collects TOT locally. Rates range from 8% to 14% depending on the city. Platforms collect and remit on your behalf for platform bookings, but if you accept direct bookings, you must remit TOT to the city yourself.

Compliance Is Accelerating: SB 346 has made compliance enforcement faster and more data-driven. The days of operating a non-registered property quietly are ending in major markets.

Frequently Asked Questions

Do I need a state license to operate an STR in California?

No. California has no statewide STR license. You only need to comply with your city or county's requirements. Research your specific location's rules before listing.

What happens if I exceed the 120-night cap in Los Angeles or 90-night cap in San Francisco?

Using SB 346 data, cities can identify excessive bookings and issue fines or compel platform removal of the listing. Repeated violations can result in loss of registration and legal penalties.

Can I operate an investment property STR in California?

It depends on the city. Most major urban markets (LA, SF) restrict STRs to primary residences only. San Diego allows investment STRs via Tier 3 lottery (extremely limited). Palm Springs allows investment properties freely. Desert and rural markets are generally more permissive than coastal or urban areas.

Do I have to collect and remit Transient Occupancy Tax myself?

If guests book through Airbnb, VRBO, or other platforms, the platform collects and remits TOT on your behalf. If you accept direct bookings, you must remit TOT to your city yourself. Failure to remit can result in substantial penalties and back taxes.

What does SB 346 mean for hosts in 2026?

SB 346 requires platforms to share host data with cities for enforcement. For compliant hosts, this changes nothing. For non-compliant hosts, it means listings are easier to identify and remove. Enforcement is faster and more data-driven than ever before.

Should I hire a property manager to ensure STR compliance?

If you own multiple properties or operate in restrictive markets like LA or SF, professional management is highly recommended. A property manager ensures registration compliance, night-cap tracking, TOT remittance, and ongoing adherence to city rules—and buffers you from liability if something goes wrong.
