San Diego's STRO License System Is More Competitive Than Ever — Here's How to Get In
San Diego is one of the most tightly regulated short-term rental markets in California — and the window to get licensed is narrowing. The city's Short-Term Residential Occupancy (STRO) Ordinance created a four-tier licensing system that limits who can operate, how often, and in which neighborhoods. Whole-home rentals face hard caps on total licenses citywide, and certain areas like Mission Beach operate under separate rules entirely. Hosts who try to list without a valid STRO license risk platform removal, fines, and losing any chance at a future license. If you're searching for what a San Diego STR permit costs and how the process works, this guide breaks down everything you need to know — and where to verify the current numbers directly with the city.
What San Diego's Four-Tier STRO System Actually Means for Hosts
A short-term rental (STR) in San Diego is defined as a residential property rented for fewer than one month — specifically, fewer than 30 consecutive days. Under the STRO Ordinance, which took effect in May 2023, every host must obtain a Short-Term Residential Occupancy (STRO) license before listing on any platform, including Airbnb or VRBO.
The license tier you qualify for depends on two factors: whether the property is your primary residence, and how many nights per year you intend to rent it out. The four tiers work roughly as follows:
- Tier 1 — Primary residence, rented up to a limited number of nights per year while you are present. No citywide cap on licenses in this tier.
- Tier 2 — Primary residence, rented for longer periods or while you are away. Also uncapped.
- Tier 3 — Non-primary residence or whole-home rental exceeding a defined annual night threshold. Subject to a citywide cap.
- Tier 4 — Mission Beach whole-home rentals. Subject to a separate neighborhood-level cap and a lottery system.
The citywide cap on Tier 3 licenses is set at approximately 1% of San Diego's total housing stock. That cap is not theoretical — it is actively limiting new applicants right now. Licenses are non-transferable, meaning you cannot buy a property and inherit the previous owner's STRO license. You must apply on your own, and you can only hold one license at a time.
Mission Beach operates under its own percentage-based cap separate from the citywide figure, and its waitlist has been closed. If you are targeting that neighborhood, contact the city directly to understand current availability before making any investment decisions.
How to Apply for a San Diego STRO License — And What It Will Cost You
Because our verified source data does not include the current fee schedule directly from San Diego's official records, you should verify all current license fees at sandiego.gov/treasurer/short-term-residential-occupancy. Competitor sources have cited fee ranges for different tiers, but fees can change, and only the city's official portal reflects what you will actually owe at the time of application.
Here is what the application process generally involves:
- Determine your tier. Before you start an application, identify whether your property qualifies as a primary residence and how many nights per year you plan to rent. Your tier determines your fee, your eligibility, and whether you face a cap.
- Create an account on the city's STRO portal. San Diego processes STRO applications through its online licensing system. Visit the city treasurer's office website to access the portal.
- Gather your documents. Typical requirements include proof of primary residency (if applying for Tier 1 or 2), a valid government-issued ID, property ownership or lease documentation, and your property's address. The city may also require proof of a Transient Occupancy Tax (TOT) account registration.
- Submit your application and pay the license fee. Fees vary by tier. Contact the permit office or check sandiego.gov for the current amount before submitting.
- Wait for approval. For capped tiers, approval is not guaranteed even if your application is complete. Tier 3 applicants may face a queue based on available licenses. Tier 4 applicants in Mission Beach must navigate the lottery process if and when it reopens.
Licenses run for two years. You will need to renew before expiration to keep operating legally. Missing your renewal window can mean starting the application process over — and, for capped tiers, losing your place entirely.
STR Comply monitors San Diego's STRO portal weekly and sends you an alert the moment fees, caps, or application requirements change — so you never miss a compliance deadline.
Ongoing Obligations Every Licensed San Diego STR Host Must Meet
Getting your STRO license is only the beginning. San Diego imposes ongoing operational requirements that hosts must meet throughout the life of the license.
Transient Occupancy Tax (TOT): All licensed STR hosts in San Diego are required to collect and remit Transient Occupancy Tax from guests. The rate varies depending on the zone your property is located in. Verify the current rate applicable to your property at sandiego.gov/treasurer/taxcollections/tot before listing. Platforms like Airbnb collect and remit TOT on behalf of hosts in some jurisdictions, but you are responsible for confirming whether that arrangement applies to your specific listing.
Rental Unit Business Tax (RUBT): In addition to TOT, San Diego requires STR operators to pay the Rental Unit Business Tax annually. Verify the current amount directly with the city treasurer's office.
Good Neighbor Standards: The STRO Ordinance requires hosts to maintain what the city calls Good Neighbor compliance. This includes providing guests with a written set of house rules, posting noise and occupancy guidelines inside the unit, and maintaining a 24/7 local contact — someone who can respond to a complaint or emergency at the property within a defined response window. That contact does not have to be you personally, but they must be reachable at all times during a guest stay.
Safety equipment: Licensed STRs must meet basic safety equipment requirements including functioning smoke detectors, carbon monoxide detectors, and fire extinguishers. These are not optional.
License display: Your STRO license number must appear in every listing on every platform. San Diego and the platforms themselves use this number to cross-reference compliance. Listings without a valid license number can be removed.
Hosts using STR Comply get a personalized compliance checklist for their property type and tier, so nothing falls through the cracks at renewal time.
What Happens If You Skip the License — San Diego's Enforcement Reality
San Diego does not treat unlicensed STR operation as a minor paperwork issue. The city has invested in enforcement infrastructure, and the consequences of non-compliance are real.
Fines: Unlicensed operators face fines for each violation. The city can issue fines per day of unlicensed operation. Check sandiego.gov for the current fine schedule, as amounts can be updated by the city.
Platform delisting: Airbnb and VRBO have agreements with San Diego to enforce the STRO licensing requirement. If the city flags your listing as unlicensed, the platform can remove it — sometimes before you even receive a formal notice from the city.
License ineligibility: Hosts who operate illegally may be barred from applying for a STRO license in the future. In a market where Tier 3 licenses are already severely limited, losing your eligibility is a significant long-term financial consequence.
Neighbor complaints: San Diego routes neighbor complaints through a dedicated system. A pattern of complaints — about noise, occupancy violations, or failure to respond to issues — can trigger a license review or revocation even for hosts who are licensed.
The most common mistakes that cause application rejections include: applying for the wrong tier, failing to register a TOT account before submitting, submitting inadequate proof of primary residency, and listing a property before the license is officially issued. Do not list until you have a license number in hand.
