California STR Laws 2026: Complete Guide for Hosts

Key takeaways: California short-term rental rules are not statewide. They are set by each city and county, which makes compliance highly location-specific.

• No statewide STR license: Every city sets its own permits, taxes, and rules
• Zoning comes first: In many areas, zoning determines legality before permits
• 30-day rule: Stays under 30 days are generally treated as STRs
• Most hosts need multiple approvals: STR permit, business registration, and TOT registration are common requirements
• City rules vary widely: Los Angeles, San Francisco, San Diego, Palm Springs, and others each have different caps and restrictions
• Primary residence rules are common: Many cities restrict or ban non-owner-occupied STRs
• Tax compliance is mandatory: Rental income must be reported, and TOT applies locally
• Enforcement is tightening: Laws like SB 346 give cities more tools to track and enforce compliance
• Location matters most: The same property can be legal or illegal depending on the exact address

Staying compliant is only part of running a successful STR. Hostex helps automate guest messaging, calendar syncing, and operational workflows, so you can focus on your guests instead of repetitive admin work. Plans start at $4.90 per month.

What Counts as a Short-Term Rental in California?

In most California cities and counties, a short-term rental (STR) is a stay of fewer than 30 consecutive days. This threshold is widely used in local lodging and transient occupancy tax regulations across the state.

Key details:

• The 30-day rule generally applies to homes, condos, apartments, ADUs, and private rooms
• Hotels, motels, bed-and-breakfasts, and timeshares are usually regulated under separate rules
• Stays of 30 days or longer typically fall under California landlord-tenant laws
• Some jurisdictions use “short-term rental” and “vacation rental” interchangeably, while others treat them differently

Before listing a property, check how your city or county defines an STR and which property types qualify.

Does California Have a Statewide STR License?

No. California does not issue a statewide short-term rental license or registration.

Instead, STRs are regulated at the city and county level.

In practice, this means:

• There is no single application that allows you to operate statewide
• Permit requirements, fees, and operating rules vary by jurisdiction
• A property that is legal in one city may be prohibited in the next

California sets broader rules for areas such as taxation, housing, and building standards. However, your local government determines whether and how you can operate a short-term rental.

The State Framework: Laws That Shape Local STR Rules

However, several state laws still influence how local governments regulate short-term rentals.

Understanding these rules helps explain why many cities have similar requirements around safety, taxation, and compliance.

California Building Standards Code

Local STR ordinances often incorporate building and safety standards from the California Building Standards Code, overseen by the Building Standards Commission.

Cities may require self-certification or inspection to confirm compliance with smoke detectors, carbon monoxide alarms, fire extinguishers, and emergency exit requirements.

SB 346: The Short-Term Rental Facilitator Act

SB 346 is one of the most important recent developments for California hosts. The law allows cities and counties to require platforms such as Airbnb and Vrbo to share listing information for tax and enforcement purposes.

For hosts, the practical impact is straightforward:

• Local governments may gain better visibility into active STR listings
• Platforms may be required to display local permit or registration numbers
• Cities can more easily identify listings that do not meet local requirements

SB 346 does not create new permit requirements for hosts. Instead, it gives local governments stronger tools to enforce existing rules.

Franchise Tax Board: Reporting Rental Income

Income earned from a short-term rental is generally taxable in California.

Hosts must report rental income on their state tax returns and maintain records of income and deductible expenses.

If you operate multiple properties, use an LLC structure, or generate significant rental income, consider working with a qualified tax professional.

Registration and Licensing Requirements for STR in California

Although requirements vary by jurisdiction, most California hosts complete a similar compliance process before accepting guests.

1. Business Registration

Many cities require you to register a business entity or obtain a general business license. Forming an LLC is optional but often recommended for liability protection.

2. Transient Occupancy Tax (TOT) Certificate

Most California jurisdictions impose a transient occupancy tax on stays of fewer than 30 days.

Rates often range from 10% to 15% or higher once local assessments are included.

Ter em mente:

• Airbnb and other platforms may collect and remit TOT in some jurisdictions
• You may still need your own TOT registration or certificate
• The host remains responsible for ensuring local tax obligations are met
• Unpaid taxes can result in penalties, interest, and back assessments

3. STR Permit or Registration

Most municipalities require a specific STR permit or registration for each rental unit, renewed annually. Expect to pay application and renewal fees, frequently in the hundreds of dollars.

4. Display Your License Number

An increasing number of California cities require hosts to display their registration or license number on every online listing. Platforms are increasingly verifying these numbers automatically.

---

Zoning: The Single Most Important Factor

Many new hosts focus on permits first. In reality, zoning is often the issue that determines whether an STR is legal at all.

A permit cannot authorize short-term rentals in a zone where they are not allowed.

Common zoning patterns in California:

1. STRs may be allowed in some residential zones, but only with specific conditions
2. Unhosted entire-home rentals are often capped or restricted, especially in dense coastal cities
3. Some neighborhoods or overlay zones prohibit STRs entirely
4. Coastal properties may require separate approvals under the California Coastal Act before local STR rules apply
5. ADUs (Accessory Dwelling Units), in-law units, and similar structures may be restricted or prohibited for STR use

When in doubt, verify the zone for your parcel and check the use tables in your local zoning code.

Primary Residence Rules and Annual Caps

Many California cities treat hosted and unhosted rentals differently.

Hosted home-sharing, where the host remains on-site, often faces fewer restrictions. Entire-home rentals typically receive closer scrutiny.

Common provisions include:

• The STR property must be your primary residence (you must live there for a minimum number of days per year)
• Annual caps limit the total number of days you can rent (often 120 to 180 days for unhosted rentals)
• Some cities allow unlimited hosted home-sharing but restrict unhosted rentals
• Guest occupancy limits: often 2 adults per bedroom, capped at around 10 adults per unit

Short-Term Rental Rules in California’s Major Cities

California does not have a one-size-fits-all approach to short-term rentals.

A property that qualifies in one city may be prohibited just a few miles away. Before investing in an STR, always review the rules that apply to your specific address.

Here are the requirements in several of California’s largest short-term rental markets.

City	Primary Residence Required	Annual Cap	Registration Required
Los Angeles	Sim	120 / 180	Sim
San Francisco	Sim	90	Sim
San Diego	Depends on Tier	Varies	Sim
San Jose	Geralmente	Varies	Sim
Palm Springs	No in some zones	Varies	Sim
Pasadena	Geralmente	Varies	Sim

1. Los Angeles

Los Angeles operates under its Home-Sharing Ordinance, which took effect in 2019. The city primarily allows home-sharing in a host’s primary residence.

Key requirements:

• Primary residence only
• 120-day annual limit for unhosted stays
• Extended Home-Sharing approval may increase the cap to 180 days
• City registration required
• Registration number must appear on listings
• 14% transient occupancy tax applies
• Most second homes and investment properties cannot operate as STRs
• Existing rent stabilization protections still apply

2. San Francisco

It was one of the first major U.S. cities to actively regulate short-term rentals. As a result, San Francisco registration and primary residence requirements are strictly enforced.

Key requirements:

• Registration is required before listing
• Property must be your primary residence
• 90-night annual cap for unhosted rentals
• No cap on hosted stays
• Platforms must verify registration status
• 14% TOT plus a $1.75 nightly Tourism Improvement District fee

3. San Diego

San Diego uses a tiered licensing system that treats hosted and whole-home rentals differently.

Key requirements:

• Tier 1 licenses apply to hosted rentals
• Tier 2 licenses cover many whole-home rentals
• Registration is required through the city’s licensing program
• Entire-home rentals are generally limited to eight guests
• 10.5% TOT plus a 2% Tourism Marketing District assessment
• Noise, parking, and trash regulations are actively enforced

4. San Jose

San Jose permits both hosted and certain unhosted short-term rentals, although requirements vary by property type and location.

Key requirements:

• Hosted rentals generally require the property to be a primary residence
• Some non-primary residence rentals may qualify with additional approvals
• Registration required
• 10% transient occupancy tax
• Noise, parking, and neighborhood standards apply

5. Palm Springs

Palm Springs is one of California’s most regulated vacation rental markets. Enforcement is active, and compliance requirements are detailed.

Key requirements:

• STRs allowed only in approved zoning areas
• Neighborhood concentration limits apply
• Annual registration required
• Periodic inspections may be required
• A local contact must be available 24/7
• 11.5% TOT plus a $2.25 nightly assessment

6. Pasadena

Pasadena allows short-term rentals but requires hosts to meet licensing, safety, and insurance requirements.

Key requirements:

• Primary residence required for most STR operations
• Annual registration required
• Proof of insurance may be required
• Occupancy limits vary by property size
• Smoke detectors, CO alarms, and emergency information must be provided
• 11.11% transient occupancy tax

7. Cities Where STRs Face Tight Restrictions

Not every California city welcomes short-term rentals. In some locations, restrictions are so extensive that operating legally can be difficult.

Examples include:

• Santa Monica: Non-hosted STRs are effectively prohibited. Hosted home-sharing remains legal with registration.
• Berkeley: Hosted rentals are allowed, but unhosted rentals face significant restrictions.
• Irvine: Zoning and land-use rules make STR operations difficult in many residential neighborhoods.
• Unincorporated areas: County regulations often apply and may differ substantially from those of nearby cities.

Always verify local rules before purchasing or listing a property.

Additional Compliance Requirements in California

Regardless of your city, most California jurisdictions require some combination of the following:

1. Local Contact Requirements

Many California cities require a local contact person for short-term rentals. This person must be available to respond to complaints, emergencies, or other issues that arise during a guest’s stay.

The requirement is especially common in vacation rental markets and for unhosted properties where the owner is not present.

Depending on the jurisdiction, the contact person may need to:

• Be available 24 hours a day
• Respond within a specified timeframe
• Handle noise, parking, trash, or occupancy complaints
• Coordinate with local authorities when necessary

Before operating an STR, check whether your city requires a designated local contact and whether specific response standards apply.

2. Insurance Considerations

California does not require statewide short-term rental insurance. However, relying solely on a standard homeowner policy can create significant gaps in coverage.

Many homeowner policies exclude or limit coverage for commercial rental activity. As a result, hosts should review their insurance carefully before accepting guests.

At a minimum, confirm that your coverage addresses:

• Guest injuries and liability claims
• Accidental property damage
• Danos causados por hóspedes
• Loss of rental income following a covered event

Many professional hosts choose dedicated vacation rental insurance for broader protection and fewer coverage exclusions.

3. Penalties for Non-Compliance

Failing to follow local STR regulations can lead to serious consequences.

While penalties vary by city and county, enforcement actions may include:

• Administrative fines
• Suspension or revocation of permits
• Orders to stop operating
• Back taxes, interest, and penalties related to unpaid TOT
• Legal or administrative enforcement proceedings

In jurisdictions that adopt enforcement measures under SB 346, platforms may also be required to assist with local compliance efforts. As a result, non-compliant listings may face additional scrutiny or removal under local enforcement programs.

The exact penalties depend on where your property is located. Always review the rules enforced by your city or county.
