STRO permits, TOT, and staying compliant in San Diego

To run a short-term rental in the City of San Diego legally, you generally need three things working together: a Short-Term Residential Occupancy (STRO) license for the property, a way to collect and file Transient Occupancy Tax (TOT) on your guests' stays, and the Tourism Marketing District (TMD) assessment that rides alongside it. Miss any one of them and the fines, back taxes, and license risk usually cost far more than doing it right the first time. Rules, rates, and deadlines change, so treat everything below as a map — and verify the specifics on the City of San Diego's official STRO page before you act.

What is an STRO license and why do the tiers matter?

The STRO license is the city's permission slip to rent a home for short stays. The important thing most owners miss is that it is not one-size-fits-all: San Diego structures licenses into tiers that depend on how the home is used — for example, whether you are renting part of the home you live in, renting a whole home for a limited number of days per year, or operating a whole-home rental as a dedicated business.

The higher tiers, which allow the most whole-home short-term nights, are the most sought-after and have historically been the most limited in number. That scarcity is exactly why the tier you qualify for shapes your entire strategy. We deliberately won't quote tier numbers or caps here because the city adjusts them — confirm which tier your property fits and how many are available on the official STRO page.

What is Transient Occupancy Tax and who actually pays it?

Transient Occupancy Tax is a tax on the guest's stay — the guest pays it, but you are responsible for collecting it and filing it with the city. That distinction trips up new owners constantly. If a booking platform collects and remits TOT on your behalf for some stays, you still typically need to be registered and to account for any stays the platform doesn't cover.

The mechanics that matter:

• You register the property with the city's tax program and receive a certificate.
• TOT is charged on top of the nightly rate and applicable fees on qualifying stays.
• You file returns on a set schedule — often monthly — even in months with no bookings.

We are intentionally not printing a percentage here because the rate is set by the city and can change. Pull the current TOT rate and filing frequency directly from the City of San Diego before your first return is due.

What is the Tourism Marketing District assessment?

Alongside TOT, San Diego lodging stays generally carry a Tourism Marketing District (TMD) assessment — a separate charge that funds regional tourism promotion. For owners, the practical takeaway is simple: it is an additional line that gets collected and remitted much like TOT, on a similar cadence, and it is easy to forget precisely because it is separate. Budget for it, collect it correctly, and file it on time. As with everything else here, confirm the current assessment rate and rules on the city's official resources rather than relying on a number from a blog.

When are renewals and filings due, and what happens if you miss them?

Compliance is not a one-time event — it is a calendar. STRO licenses come up for renewal, TOT and TMD returns are filed on a recurring schedule, and each has its own deadline. Missing them tends to cascade:

• Late TOT or TMD filings typically accrue penalties and interest on the amount owed.
• A lapsed STRO license can mean you are operating unlicensed — which can carry its own enforcement action and jeopardize your ability to re-license.
• Repeated or serious violations can put your license itself at risk, which for a whole-home operator is the entire business.

The dollar figures and grace periods change, so we won't hard-code them. The durable advice: know your renewal date and your filing cadence, and never let a zero-booking month convince you a return isn't due.

What does Cardo handle for owners?

This is precisely the kind of work we take off an owner's plate. For the homes we manage, we keep the compliance calendar, make sure stays are charged correctly for TOT and TMD, handle the recurring filings, and track renewal dates so nothing lapses. You still own the license and the obligation — but you are not the one remembering that a return is due on a slow month. If you want to understand how that fits alongside pricing and guest management, start with how we work with owners, and if you're weighing whether a property pencils out, our earnings estimate is the right first step.

Quick answers

Do I need an STRO license for every short-term rental in San Diego?

Generally yes — the City of San Diego requires an STRO license to legally offer a residence for short stays, with the specific tier depending on how the home is used. Confirm your tier on the city's official STRO page.

Who pays the Transient Occupancy Tax?

The guest pays it, but the owner is responsible for collecting it and filing returns with the city — typically on a recurring schedule, even in months with no bookings.

What is the Tourism Marketing District assessment?

It's a separate charge on lodging stays that funds regional tourism promotion, collected and remitted alongside TOT. Verify the current rate with the city.

What happens if I miss a filing or renewal?

Late filings usually accrue penalties and interest, and a lapsed license can mean operating unlicensed — which risks enforcement and your ability to re-license. Know your deadlines and treat them as fixed.
