San Diego Short-Term Rental Regulations: 2026 Guide for Airbnb Hosts

If you are hosting on Airbnb, VRBO, or another platform in San Diego, understanding the city's short-term rental regulations is non-negotiable. Non-compliance can result in fines, license revocation, and removal from platforms. This guide covers everything you need to know about San Diego short-term rental regulations as of 2026.

The Basic Framework

San Diego's short-term rental regulations divide properties into three tiers based on usage type:

• Tier 1 — Home Share: You live on the property and rent a room or your home while present. Annual permit required. No night cap.
• Tier 2 — Part-Time Whole Home: You rent your primary residence when you are away for up to 90 nights per year. Annual permit required.
• Tier 3 — Full-Time Whole Home: You rent a property that is not your primary residence for more than 90 nights per year. Most limited tier — citywide cap applies.

Permit Requirements

All short-term rental operators in San Diego must obtain a Short-Term Residential Occupancy (STRO) license through the city's Development Services Department. You will also need a Transient Occupancy Tax (TOT) certificate and must collect and remit TOT on all rental income.

Platforms like Airbnb automatically collect and remit TOT in San Diego, but hosts are still responsible for having their own certificate on file.

Primary Residence Rule

One of the most important San Diego short-term rental regulations is the primary residency requirement. Under Tier 2 and Tier 3 rules, you must demonstrate that the property is your primary residence (for Tier 2) or meet specific owner-operator criteria. Vacation investment properties face the most restrictions under the citywide cap.

Mission Beach Exception

Mission Beach has its own rules under San Diego short-term rental regulations, with a separate cap that allows a higher density of whole-home rentals given the area's long history as a vacation destination. Hosts in Mission Beach should verify their specific tier eligibility separately.

Enforcement and Penalties

San Diego actively enforces short-term rental regulations through complaint-driven investigations and platform data sharing agreements. First-time violations typically result in a warning and a cure period. Repeat violations can result in fines of $1,000 to $5,000 per violation day and revocation of the STRO license.

Staying Compliant

Post your STRO license number in your listing. Respond promptly to neighbor complaints. Keep accurate records of nights rented. Renew your permit annually. Work with a local property manager familiar with San Diego short-term rental regulations to avoid costly mistakes.

Understanding and complying with San Diego short-term rental regulations is the foundation of a sustainable hosting business. The rules exist to protect both guests and neighbors — and compliant hosts tend to have fewer disputes and better long-term outcomes.
