California is the largest short term rental market in the United States — and one of the most heavily regulated. Between Los Angeles, San Diego, San Francisco, Palm Springs, and dozens of coastal and mountain communities, the state generates billions in vacation rental revenue each year. But California short term rental laws are anything but simple.
There is no single statewide short term rental law in California. Instead, each city and county creates its own short term rental regulations, permits, and tax requirements. That means the rules for operating a short term rental property in San Diego are completely different from those in Los Angeles, San Francisco, or Santa Monica. Property owners managing short term rentals across multiple California cities need to comply with each jurisdiction's separate ordinances.
This guide covers how California regulates short term rentals at the state and local level — including permits, transient occupancy tax, zoning, primary residence requirements, and what happens when you don't comply.
How California Defines Short Term Rentals
Most California cities define a short term rental as any residential dwelling unit (or portion of one) rented for fewer than 30 consecutive days. This includes whole-home vacation rentals, hosted stays where the owner remains on-site, and individual rooms listed on platforms like Airbnb and VRBO.
The key distinction in California law is between a residential dwelling unit used as a rental and traditional lodging like hotels. Rentals in residential areas are subject to both the city's municipal code and any applicable HOA rules. Some cities further distinguish between hosted and un-hosted properties — and the regulations differ significantly depending on which category yours falls into.
Los Angeles Short Term Rental Regulations
Los Angeles has one of the strictest short term rental programs in California. The city's Home Sharing Ordinance, enforced since 2019, sets clear boundaries on how short term rentals can operate.
Key requirements for LA short term rentals:
- Short term rentals must be at the host's primary residence — you must live in the property at least 6 months per year
- A registration is required through the city's Home Sharing program, including a business registration certificate
- Un-hosted short term rentals (where the host is not present) are limited to 120 days per year unless the host obtains an Extended Home Sharing permit
- Hosted short term rentals (host on-site) have no day cap
- The city's lodging tax must be collected and remitted
- Properties with outstanding building code violations cannot register
- Rent-stabilized units and affordable housing cannot be used as short term rental properties
LA actively enforces these rules. The city has partnered with platforms to remove listings that lack valid short term rental registration numbers, and fines for violations are substantial.
San Diego Short Term Rental Laws
San Diego overhauled its short term rental regulations in 2022, creating a tiered system that significantly changed the landscape for vacation rental operators.
San Diego's short term rental program has two tiers:
Tier 1 — Mission Beach: Whole-home short term rentals are allowed in Mission Beach with a short term rental permit and a cap on the total number of permits issued.
Tier 2 — Citywide: Outside Mission Beach, whole-home short term rentals are being phased down. The city is reducing the number of allowed vacation rental permits in residential areas over time. Hosted short term rentals (primary residence, host on-site) remain allowed citywide.
All San Diego operators must obtain a permit, collect transient occupancy tax, and comply with the city's municipal code for noise, parking, and occupancy. The primary residence requirement applies to most categories — you cannot simply buy an investment property and list it as a vacation rental in most San Diego neighborhoods.
San Francisco Short Term Rental Regulations
San Francisco's short term rental regulations are among the tightest in California. The city requires:
- Short term rental registration through the Office of Short-Term Rentals
- The property must be the host's primary residence (at least 275 nights per year)
- Un-hosted short term rentals are capped at 90 nights per year
- Hosted short term rentals have no night cap
- A business registration certificate is required
- Tax collection and remittance on all stays
- Quarterly reporting to the city on rental activity
- Liability insurance of at least $500,000
San Francisco actively monitors compliance and has issued significant fines to property owners operating unregistered short term rental properties. The city's primary residence requirement effectively prevents investors from operating non-owner-occupied vacation rentals.
Santa Monica Short Term Rental Laws
Santa Monica was one of the first California cities to crack down on short term rentals. The city essentially bans un-hosted vacation rentals — only hosted home sharing at the operator's primary residence is allowed.
Santa Monica requires a business license, registration, and tax collection on all stays. The city has pursued aggressive enforcement, including lawsuits against platforms and individual property owners operating illegal vacation rental properties. Fines can reach thousands of dollars per violation.
Palm Springs Short Term Rental Regulations
Palm Springs takes a different approach than LA and San Francisco. The city allows both hosted and un-hosted short term rentals but requires a vacation rental permit and strict compliance with its short term rental regulations.
Key Palm Springs rules:
- A short term rental permit is required — the application includes a property inspection
- A local contact person must be available 24/7 to respond to complaints within 30 minutes
- Maximum overnight occupancy limits are strictly enforced (2 per bedroom + 2)
- Daytime gathering limits restrict the total number of people on the short term rental property
- Lodging tax applies to all vacation rental stays
- Noise monitoring may be required
- Repeat violations can lead to permit revocation
Palm Springs is a strong market for vacation rentals, but the city doesn't hesitate to revoke permits from problem properties. The maximum overnight occupancy rules are especially important — exceeding them is one of the most common violations.

Short term rental regulations vary across every California city. Here are a few other notable markets:
Sacramento: Requires permits, with a primary residence requirement for most operators. Both hosted and un-hosted rentals are allowed at the host's primary residence. Transient occupancy tax applies.
Oakland: Requires registration and limits un-hosted vacation rentals. The property must be the operator's primary residence. A business license and tax collection are mandatory.
Big Bear / Lake Arrowhead: San Bernardino County regulates vacation rentals in mountain communities. Permits, lodging taxes, and compliance with fire safety standards (critical in wildfire-prone areas) are required.
Sonoma / Napa: Wine country communities have their own short term rental regulations. Many have caps on the number of vacation rental permits issued, especially in unincorporated county areas. The regulations aim to balance tourism revenue with housing availability.
If you're operating short term rentals in any California city, check the specific city's municipal code before listing. Assumptions based on another city's rules will get you in trouble.
Transient Occupancy Tax
Every California city that allows short term rentals imposes a transient occupancy tax — essentially the same tax hotels pay. Rates vary by city but typically range from 10% to 14% of the rental price.
Short term rental operators must:
- Register with the city for transient occupancy tax collection
- Collect the tax from guests on every booking
- Remit payments on the city's schedule (monthly or quarterly)
- File regular tax returns
Some platforms collect and remit the tax automatically in certain California jurisdictions, but verify what's covered. Property owners are ultimately responsible for ensuring all obligations are met. Late payments trigger penalties and interest.
Primary Residence Requirements
Many California cities now require that short term rental properties be the operator's primary residence. This is the single biggest regulatory trend in California short term rental law — it effectively prevents investors from buying homes purely for vacation rental use.
The primary residence requirement means:
- You must live in the property for a minimum number of days per year (varies by city — 275 nights in San Francisco, 6 months in LA)
- You can rent your primary residence as a short term rental when you're away, or rent a portion while you're home
- Investment properties that are not the owner's primary residence cannot be listed as short term rentals in most cities
- Documentation may be required (utility bills, voter registration, tax filings) to prove primary residence status
Cities with primary residence requirements are specifically targeting the conversion of long-term housing into vacation rental properties — a major concern in California's tight housing market.
Permits, Registration, and Business Licenses
The permitting process varies by city, but California short term rental operators typically need:
- Short term rental registration or permit — Apply through the city's planning department or online portal.
- Business registration certificate — Most California cities require one for any commercial activity, including rentals.
- Transient occupancy tax registration — Separate registration with the city's tax or finance department.
- Property inspection — Some cities inspect short term rental properties before issuing permits. Safety standards include smoke detectors, carbon monoxide detectors, fire extinguishers, and posted emergency information.
- Insurance — Many cities require proof of liability insurance. Standard homeowners insurance doesn't cover short term rental operations — you need specialized vacation rental coverage.
Keep your registration current. Expired permits are treated the same as no registration — you'll face fines and potential platform delisting.
Homeowners Associations and Short Term Rentals
Even if your California city allows short term rentals, your homeowners association may not. HOA rules can prohibit vacation rentals entirely, impose minimum stay requirements, limit rental frequency, or require board approval before listing.
An HOA restriction overrides city permissions. Before investing in a property in an HOA-governed community, review the CC&Rs carefully. Violating HOA rules can result in fines, legal action, and property liens.
Penalties and Enforcement
California cities are among the most aggressive in the country when it comes to short term rental enforcement. Common penalties include:
- Fines ranging from $500 to $5,000+ per violation, per day
- Platform delisting — cities share enforcement data with Airbnb, VRBO, and other platforms
- Permit revocation for repeated violations or excessive complaints
- Criminal charges in extreme cases (some cities classify repeat violations as misdemeanors)
- Back taxes, penalties, and interest for uncollected lodging taxes
- Legal action — cities like Santa Monica and San Francisco have sued individual property owners
The bottom line: operating an unregistered or non-compliant short term rental in California is increasingly risky. Enforcement technology, platform cooperation, and neighbor complaints make it harder to fly under the radar.
Managing compliance across California's patchwork of short term rental regulations is complex. Professional property management handles permitting, tax collection, and regulatory compliance so property owners can focus on returns rather than paperwork.
