San Diego Short Term Rental Listing and Notice Requirements

San Diego wants two numbers from you, not one, and it wants them in two separate places. The Short-Term Residential Occupancy licence number is the one every host remembers. The Transient Occupancy Tax certificate number is the one that gets left off.

Both have to appear on the exterior notice at the property and on every advertisement for it, which includes the Airbnb listing, the Vrbo listing and anywhere else the place is marketed. There are also notices the city requires inside the unit. This is a short walk through all three places, and what actually has to be in each.

The Mistake Most Licensed Hosts Make: STRO Number Without the TOT Certificate Number

Most hosts assume that obtaining a Short-Term Residential Occupancy (STRO) license is the finish line. You receive your license approval email from the City of San Diego Office of the City Treasurer, copy your STRO number, paste it into your Airbnb or Vrbo listing details, and move on. That single action leaves your advertisement non-compliant.

The City of San Diego mandates that every short-term rental advertisement must display two distinct operational numbers: the STRO license number and the Transient Occupancy Tax (TOT) certificate number. The STRO license authorizes the property use under its specific tier. The TOT certificate proves the property is registered to collect and remit the city lodging taxes, which are structured across three distinct geographic zones under Measure C. You can review the exact rate tiers in this guide to San Diego transient occupancy tax.

The two registrations are easy to conflate because both run through the Office of the City Treasurer, but they do different jobs, and the city asks for both by number. If one is missing from an advertisement, the advertisement does not meet the requirement.

A third alleged violation of host operating requirements at the same unit or by the same host within 12 months can result in a referral to a city hearing officer with the authority to revoke your STRO license. Correcting your advertisements takes five minutes. Log into your hosting dashboards and format your description header immediately: 'STRO License: STR-XXXXX | TOT Certificate: XXXXXX'. Check your Vrbo listing, your direct booking site, and any social media pages marketing the property. The rule applies across every public channel.

Place 1, Your Listing: What Every Advertisement Must Show

The city's requirement is that both numbers appear on every advertisement for the property. Read as written, that reaches any medium used to solicit a booking: the major travel platforms, a direct booking site, and anywhere else the place is listed. Check the City Treasurer's Short-Term Residential Occupancy page for the current wording before you rely on any summary of it, including this one.

First, every advertisement must prominently display both your STRO license number and your TOT certificate number. On platforms like Airbnb, input your STRO number into the designated regulatory field in the platform settings, but also insert both numbers into the first two lines of your public property description. Certain listing aggregators fail to render third-party platform regulatory fields correctly across different mobile interfaces. Placing the plain text directly in the public summary guarantees that any compliance reviewer or guest immediately sees both registrations.

Second, do not advertise a stay your licence does not allow. Tier 3 and Tier 4 whole-home licences carry a two-consecutive-night minimum per guest, so a one-night weekend booking is not something a whole-home licence supports. Those same tiers also require at least 90 days of licensed use a year, which is a floor rather than a ceiling and catches owners who only meant to rent occasionally. Both of those, and where each tier's day limits sit, are worked through in how many days can you rent a San Diego Airbnb.

On guest counts, take your permitted occupancy from your own approved application rather than from a rule of thumb, and ask the City Treasurer if the application does not make it plain.

Place 2, The Exterior Notice: What Must Be Visible from the Sidewalk

The second mandatory disclosure location is the physical exterior of your rental property. The City of San Diego requires hosts to post an exterior notice designed to give immediate neighbors and city enforcement personnel a direct way to report neighborhood disturbances or verify operational legitimacy without trespassing on the property.

The requirement the city states is that the notice is visible from the sidewalk. That is the test to apply: stand on the public sidewalk and see whether you can read it without stepping onto the property.

Three things go on it:

1. The STRO license number.

2. The Transient Occupancy Tax certificate number.

3. The host or local contact details.

The city does not publish a specification for the sign itself, so use judgement on materials and size, and keep it legible. A faded or unreadable notice is not doing the job the requirement asks of it, and the contact details on it are the ones a neighbor will actually call.

Place 3, Inside the Unit: The Notices and Documents Guests Must Receive

The third place is inside the unit, and here the city names specific items rather than a general packet.

A human trafficking awareness notice must be posted inside the unit. Separately, the host must hold proof of having completed a trafficking awareness course; that is a record you keep, not something you post.

Every guest must be given the city's Good Neighbor Policy, which sets expectations on noise, trash and parking. Note the wording: it is given to guests, so a house manual or welcome guide that reproduces it is doing the work, and it also gives your local contact something concrete to point at when asking a guest to quiet down.

California Fire Code compliance applies to the unit as well.

What the city does NOT publish, and what you should therefore not invent for your own notice, is a set of quiet hours, a required parking format, or a mandated trash schedule. Put your own house rules in the welcome guide by all means, but do not present them to guests as city requirements, and take anything you are unsure about to the City Treasurer rather than copying another listing.

Keeping Your Contact Details Current: The 30-Day Update Rule

Holding a short-term rental license is an ongoing administrative commitment. Your operating credentials are bound directly to your designated local contact person. The City of San Diego requires this designated local contact to respond in person or by phone within one hour of receiving a complaint and take action to resolve the issue. You can read the specific response rules in this guide to San Diego STRO local contact requirements.

If your local contact changes their phone number, steps down, or you hire a new property management company, the municipal code requires you to submit an official update to the Office of the City Treasurer. Letting this update slip leaves your license vulnerable. If an enforcement officer or neighbor calls the number listed on your exterior sign and gets a disconnected tone, your property fails its operational standard.

When updating your contact details with the city, you must complete the cycle across all three physical disclosure zones:

First, update the details with the Office of the City Treasurer, which is where the change has to be filed.

Second, update your exterior signage immediately. If your sign lists your previous contact or an obsolete phone number, install a revised placard on your gate or window the day the change occurs.

Third, swap out the interior guest notice packet to reflect the current phone number and point of contact. If you change management providers, you must also reconcile existing city filings, as outlined in this walkthrough on changing Airbnb property managers San Diego.

Atlia's staffed San Diego base covers the local-contact role and responds inside the city's one-hour window, and that is included in the management rate rather than billed as an add-on.

A Quick Compliance Checklist Before Your Next Booking

Before your next guest checks in, run through this practical punch list to confirm your property satisfies every San Diego short term rental listing and notice requirement. A five-minute check eliminates avoidable city citations.

Step 1: The Online Advertisement Audit

• Verify that your active STRO license number appears in your listing text and platform settings.

• Confirm that your valid TOT certificate number is visible in the public listing description.

• Check that your listed occupancy does not exceed your licensed capacity.

• Verify that whole-home listings reflect the two-consecutive-night minimum per guest.

Step 2: The Exterior Walkway Inspection

• Stand on the public sidewalk directly in front of the home.

• Confirm that your exterior notice is legible from that vantage point without entering the property.

• Confirm that the placard displays your STRO number, TOT certificate number, and the correct name and working phone number of your local contact.

• Replace any sign that has suffered sun fading, peeling, or water damage.

Step 3: The Interior Unit Walkthrough

• Confirm every guest receives the city's Good Neighbor Policy.

• Confirm the human trafficking awareness notice is posted, and that you hold proof of the awareness course.

• Keep your own house rules on trash, parking and noise in the welcome guide, and do not present them as city requirements.

Step 4: Operational Records Check

• Confirm that your local contact is reachable at the posted phone number and prepared to respond within one hour if dispatched.

• Check that any recent contact or operational changes were submitted to the Office of the City Treasurer within the 30-day window.

Completing these checks protects your business against administrative complaints and preserves your standing with the City of San Diego.

Conclusion

Operating a short-term rental in San Diego requires absolute operational precision. A missing TOT certificate number on a listing, or an exterior notice nobody can read from the sidewalk, is a cheap thing to get wrong on a licence that took months to secure. Atlia manages San Diego short-term rentals for a flat 10 percent of booking revenue, with repairs and supplies passed through at cost, and its San Diego base covers the local-contact role inside the city's one-hour window. The City Treasurer's Short-Term Residential Occupancy page is the authority on your own obligations, and none of this is legal advice.
