San Diego Short-Term Rental Regulations

San Diego Short-Term Rental Compliance Guide

San Diego operates a tiered licensing system for short-term rental operations through the City Treasurer's office. As of March 2026, the regulatory framework includes four distinct tiers with varying requirements, restrictions, and availability. This guide covers essential compliance information, registration procedures, tax obligations, and penalty structures to help you operate legally and avoid costly violations.

1. Registration & Licensing

San Diego requires all short-term rental operators to obtain a Short-Term Residential Occupancy (STRO) license before accepting guests. The registration process is multi-step and involves both transient occupancy tax certification and business tax registration.

Step-by-Step Registration Process

1. Obtain Transient Occupancy Tax (TOT) Certificate

   Before applying for an STRO license, you must obtain a TOT permit to collect and remit transient occupancy taxes. This is the mandatory first step and allows the city to track tax obligations for your property. Apply through the San Diego Transient Occupancy Registration System (TORS) at https://www.sandiego.gov/treasurer/short-term-residential-occupancy.

2. Set Up Rental Unit Business Tax (RUBT) Account

   Register for a business tax account if you are managing multiple units or if you are a professional manager (not the property owner). This account ensures proper tax reporting and compliance tracking across your portfolio.

3. Determine Your Tier Level

   San Diego uses four tier classifications:

   • Tier 1: Maximum 20 days/year rental; unlimited licenses available; no primary residence requirement. Lowest fee of $226.
   • Tier 2: Owner-occupied primary residence required with 275+ days/year occupancy; can rent 20–90 days annually; fee is $317.
   • Tier 3: Non-primary residence whole-home rentals; 90+ days/year minimum rental period; limited to 1% of city housing stock (896 licenses remaining as of November 2025); fee is $1,170.
   • Tier 4: Mission Beach whole-home only; waitlist closed as of October 2025; no new licenses being issued.

   Critical Gap Alert: San Diego does not permit STR operations for 21–89 days per year. You must fit into either Tier 1 (≤20 days) or Tier 2/3 (≥90 days).

4. Gather Required Documentation

   Prepare the following documents:

   • Proof of ownership or property control (deed, lease, management agreement)
   • Floor plans showing all rooms and emergency exits
   • Local emergency contact information (24/7 availability is mandatory)
   • For Tier 2 applicants: Driver's license, voter registration, utility bills, or tax returns proving primary residency
   • Business Tax Certificate (if applicable for managers)
5. Submit Application Online

   Complete your application through the City's STRO Licensing Portal. Standard processing time is 60–120 days. Monitor your application status regularly and respond promptly to any city inquiries.

6. Pay License Fee

   Pay the tiered fee corresponding to your tier level. Fees are non-refundable and do not cover your TOT collection and remittance obligations (those are separate).

7. Receive License & Display Prominently

   Once approved, you will receive your STRO license number. You must include this license number on all listings (Airbnb, VRBO, Booking.com, etc.) and display it prominently at the physical property (typically on the front door or entry area).

Tier	License Fee	Max Annual Days	Primary Residence Req.	Availability
Tier 1	$226	20 days	No	Unlimited
Tier 2	$317	20–90 days	Yes (275+ days/year)	Unlimited
Tier 3	$1,170	90+ days	No	Limited (896 licenses available)
Tier 4	N/A	N/A	N/A	Closed (Mission Beach only)

Renewal Notice: Licenses expire on a 2-year cycle. The city will notify you 60 days before expiration. Failure to renew within this window results in license forfeiture. If you hold a Tier 3 or Tier 4 license (limited availability), losing your license may prevent you from reapplying, effectively ending your ability to operate legally.

2. Tax Obligations

San Diego imposes two primary tax obligations on short-term rental hosts: Transient Occupancy Tax (TOT) and Tourism Marketing District (TMD) assessments. These must be collected from guests and remitted to the city on a regular schedule.

Transient Occupancy Tax (TOT) Rates

Effective May 1, 2025, San Diego moved from a flat 10.5% citywide rate to a zone-based tiered system. Your property's tax zone depends on its proximity to the Convention Center:

Zone	Location	TOT Rate
Zone 1	Most distant from Convention Center	11.75%
Zone 2	Mid-distance from Convention Center	12.75%
Zone 3	Closest to Convention Center	13.75%

Determine your property's zone using the City's interactive tax map at https://www.sandiego.gov/treasurer/taxesfees/tot. You must add the applicable zone percentage to each guest's nightly rate and remit it to the city.

Tourism Marketing District (TMD) Assessment

In addition to TOT, hosts must remit TMD assessments, similar to obligations imposed on traditional hotel operators. These assessments fund local tourism marketing initiatives and are calculated separately from TOT.

Tax Filing & Payment Platforms

Most short-term rental platforms (Airbnb, VRBO, Booking.com) now automatically collect and remit TOT on your behalf if your property is in an integrated jurisdiction like San Diego. However, you remain responsible for verifying accurate collection. Some hosts use third-party tax filing services or manually remit TOT directly to the San Diego Transient Occupancy Tax Collection office at https://www.sdttc.com.

Key Action: Clarify with your booking platform whether they remit TOT on your behalf or if you must handle remittance independently. Failure to remit TOT results in substantial penalties plus interest.

3. Operating Restrictions

San Diego's regulatory framework imposes strict limits on when, how long, and where you can operate a short-term rental. These restrictions are tier-dependent and rigorously enforced.

Annual Day Limits & Housing Stock Caps

• Tier 1: Maximum 20 days per year (no housing stock limit; unlimited licenses available)
• Tier 2: 20–90 days per year (must maintain 275+ days/year primary residence occupancy; no housing stock limit)
• Tier 3 & 4: Minimum 90 consecutive-day rental periods annually (limited to 1% of city housing stock; 896 Tier 3 licenses available as of late 2025; Tier 4 closed)

Critical Restriction: San Diego prohibits STR operations for 21–89 days per year. This gap exists to discourage mid-length rentals and protect long-term housing stock. You must operate as either a short-term operator (≤20 days, Tier 1) or a longer-term operator (≥90 days, Tiers 2/3).

License Limitations

• One Active License Per Host: You may hold only one active STRO license at a time. Operating multiple properties simultaneously is prohibited.
• Non-Transferable Licenses: Licenses are tied to a specific owner and property. You cannot transfer your license to another owner or use it for a different property.
• Housing Stock Cap: Tier 3 whole-home non-primary licenses are capped at 1% of city housing stock. Once this cap is reached, no new Tier 3 licenses can be issued until the housing stock grows or existing licenses are not renewed. As of November 2025, only 896 Tier 3 licenses remain available.

Good Neighbor Standards

All operators must comply with San Diego's Good Neighbor Standards:

• 24/7 Local Contact Availability: You must maintain a local emergency contact who is available 24 hours a day, 7 days a week. This person must be reachable by phone and able to address guest or neighborhood complaints immediately.
• Guest Guidelines: Provide guests with written Good Neighbor Guidelines covering noise restrictions, trash management, parking rules, and occupancy limits.
• Noise Control: Guests must maintain appropriate noise levels at all times. Noise violations incur automatic administrative fines up to $1,000 per incident.
• Trash Management: Trash containers must be stored out of public view except on collection days. Violations result in administrative citations.
• Parking Restrictions: Oversized vehicles (RVs, non-motorized vehicles, commercial trucks) are restricted or prohibited depending on neighborhood zoning. Ensure guests understand parking limitations.

4. Safety Requirements

San Diego enforces strict safety standards to protect guest welfare and property integrity. Properties must comply with all local health and safety codes.

Mandatory Safety Equipment

• Carbon Monoxide Detectors: Required if your property contains any fuel-burning appliances (gas stove, fireplace, heater, water heater). These must be functioning and tested regularly.
• Smoke Detectors: Installed in all sleeping areas and tested monthly. Replace batteries annually or when low-battery alarms sound.
• Emergency Contact Information: Display emergency contact information prominently (guest's safety officer contact, fire department, police, poison control). Include evacuation procedures and assembly points.
• First Aid Kit: Maintain a basic first aid kit accessible to guests.

Property inspections may occur, and failure to maintain safety equipment results in violations and fines. Document all maintenance and testing with photos and dated records.

5. Insurance Requirements

Standard homeowner's insurance policies do not cover short-term rental activity. You must obtain separate coverage to protect against liability and property damage.

Minimum Coverage Standards

• Liability Coverage: Minimum $1 million in liability coverage is recommended. This protects you if a guest is injured on the property and holds you responsible.
• Property Damage Coverage: Covers damage to your furnishings, appliances, and interior caused by guests.
• City Named as Additional Insured: Your insurance policy must explicitly name the City of San Diego as an additional insured. This requirement is strictly enforced.

Insurance Verification

The city may request proof of insurance upon application or during routine compliance checks. Keep current insurance documentation (declarations page and full policy) readily available and updated. If your insurance lapses, your STRO license can be suspended.

Many short-term rental platforms (Airbnb, VRBO) offer host protection insurance, but these policies typically do not meet San Diego's standalone insurance requirements. Obtain a dedicated STR liability policy from a specialty insurer.

6. Fines & Penalties

San Diego enforces compliance through substantial financial penalties. Below is a comprehensive table of common violations and associated fines.

Violation Type	Fine Range	Notes
Operating without STRO license	$1,000–$5,000 per violation	Escalates for repeat offenses; each booking may count as separate violation
Noise violation (guest or host)	Up to $1,000 administrative citation	Per incident; assessed immediately by city enforcement
Violation of Good Neighbor Standards	$300–$1,000 per day	Covers trash, parking, occupancy violations
Failure to remit TOT	Substantial penalties + interest	Amount varies; accrues daily until paid; can result in license revocation
Unauthorized occupancy or density violation	$300–$1,000 per day	Exceeding guest capacity or tier day limits
Operating without 24/7 local contact	$1,000 per violation	Non-availability or unresponsive contact results in violation
License display violation	$300–$500	Failing to display license number at property or on listings

Cumulative Impact: Violations can multiply quickly. A single property with multiple guest noise complaints could incur $3,000–$5,000 in fines within days. Repeat violations or patterns of non-compliance can trigger license revocation, effectively shutting down your operation permanently.

7. Platform vs. Host Responsibilities

Short-term rental platforms like Airbnb, VRBO, and Booking.com share compliance responsibilities with hosts, but the dividing line is not always clear.

Host Responsibilities

• Obtain and maintain valid STRO license
• Display license number on all listings and property
• Verify tier compliance (day limits, housing stock rules)
• Collect and remit TOT and TMD assessments (or verify platform is handling)
• Maintain 24/7 local emergency contact availability
• Enforce Good Neighbor Standards with guests (noise, trash, parking)
• Maintain current insurance with City named as additional insured
• Keep property compliant with safety codes (detectors, exits, etc.)

Platform Responsibilities

• Require and verify STRO license at listing activation
• Collect and remit TOT (in most cases, though this varies by platform and year)
• Provide guest education on local rules and quiet hours
• Enforce listing removals for unlicensed properties
• Assist with dispute resolution between hosts and guests

Key Takeaway: You remain ultimately responsible for compliance, regardless of platform assurances. Even if a platform claims to collect TOT, verify that remittances actually occur. Request tax documentation quarterly or annually to confirm compliance.

8. Key Deadlines & Official Resources

Critical Dates & Deadlines

• STRO Application Processing: 60–120 days from submission; monitor your application status during this period.
• License Renewal Window: 60 days before expiration; failure to renew within this window = license forfeiture and potential loss of reapplication rights (especially for Tier 3/4 holders).
• TOT Remittance Frequency: Typically monthly or quarterly, depending on your platform or direct remittance arrangement. Clarify the schedule with the tax collector or your platform.
• Insurance Proof of Current Coverage: Keep updated documents ready for verification at any time; many cities conduct random compliance audits.

Recent Changes & Future Outlook

As of March 2026, be aware of these recent regulatory changes:

• Tiered TOT Rates (May 2025): San Diego increased TOT from a flat 10.5% to a zone-based 11.75%–13.75% system. This directly impacts guest costs and your net revenue.
• Biennial License Terms (2025): License renewal cycles changed from annual to 2-year terms. Plan your renewal dates accordingly.
• Tier 3 Housing Stock Approaching Cap: With 896 licenses remaining, Tier 3 (non-primary residence whole-home) slots are limited. If you are considering expansion, apply soon before availability is exhausted.
• Tier 4 Waitlist Closure (October 2025): Mission Beach whole-home rentals are no longer accepting applications. This tier is effectively closed.

Bottom Line: San Diego's STR regulations are complex, tiered, and actively enforced. Operators must carefully track compliance across licensing, tax remittance, day limits, Good Neighbor Standards, and insurance. Violations incur substantial fines and risk license revocation. Consult the city's official resources above or engage a local STR compliance specialist if you have specific questions about your property or situation.
