Thinking about renting your San Diego home by the night? In 2026, one thing matters more than your nightly rate, your photos, or your reviews: your STRO license. San Diego’s Short-Term Residential Occupancy (STRO) ordinance decides which properties can legally host short-term guests, how many nights a year they can rent, and how much income you can realistically expect. Get the licensing wrong and you’re looking at fines of $1,000 a day. Get it right and your property becomes one of a limited, capped supply of legal vacation rentals in one of the strongest vacation markets in the country.
This guide covers the 2026 rules as they stand today — the four license tiers, what they cost, what’s still available, and the mistakes we see owners make most often.
Why San Diego’s STRO Rules Matter to Your Income
Since the ordinance took effect, San Diego has been deliberately limiting the supply of whole-home vacation rentals. Tier 3 licenses (whole-home rentals outside Mission Beach) are capped at 1% of the city’s housing stock, and Tier 4 (Mission Beach) is fully maxed out. That scarcity is a double-edged sword: it means your licensed property faces less competition and can command stronger rates —Navigating STRO compliance is easier with experienced Airbnb property management in San Diego.

but it also means an unlicensed property, or one that loses its license, can be shut down fast.
Enforcement has teeth in 2026. The city’s Building and Land Use Enforcement (BLUE) team cross-references Airbnb and Vrbo listings against the license database, and under California’s SB 346 — effective January 2026 — platforms are required to share host and listing data with the city and take down unlicensed listings. Fines start at $1,000 per day for operating without a license, and violations can lead to permanent disqualification from ever holding a license.
The takeaway for owners: licensing isn’t paperwork, it’s your revenue pipeline. No license, no income.
The Four STRO License Tiers, Explained
Everything starts with picking the right tier. Renting fewer than 31 consecutive nights inside City of San Diego limits requires a license, and your tier depends on how you use the property, whether you live there, and where it sits.
Tier 1: Part-Time (Up to 20 Days a Year)
The lightest-touch option. If you only want to rent your place a few weeks a year — say, while you’re traveling or during peak season — Tier 1 lets you host whole-home or home-share stays for 20 days or less per year, with a two-night minimum stay. You don’t need to live onsite.
Cost: $33 application fee + $193 license fee = $226, good for 2 years.
Tier 1 is not an investment strategy — 20 days of bookings won’t move the needle on a mortgage. But it’s a useful way to test the short-term rental waters or offset costs on a second home before committing.
Tier 2: Home Sharing (Host Lives Onsite)
Tier 2 is for owners who live in their primary residence at least 275 days per year and want meaningful rental income. It covers renting out a room for more than 20 days a year, or renting the whole home for up to 90 days a year while it’s still your primary residence. Proof of primary residency is required.
Cost: $33 application fee + $284 license fee = $317, good for 2 years.
There’s no cap on Tier 2 licenses, which makes it the most accessible path. The catch: you genuinely have to live there. This tier doesn’t work for investment properties where you don’t actually reside.
Tier 3: Whole-Home Rentals Outside Mission Beach
This is where serious vacation-rental investors live. Tier 3 allows whole-home rentals for more than 20 days per year anywhere in the city outside the Mission Beach planning area. You don’t need to live in the property, so it works for pure investment purchases.
Cost: $41 application fee + $1,129 license fee = $1,170, good for 2 years.
The critical constraint: the cap. Tier 3 licenses are limited to 1% of San Diego’s housing stock. As of late September 2026, roughly 800 Tier 3 licenses remained available — real, but shrinking. When the cap is hit, no new licenses are issued until someone surrenders or loses one.
Tier 4: Whole-Home Rentals in Mission Beach
Same whole-home rules as Tier 3, but for properties inside the Mission Beach planning area, with a two-night minimum stay. Mission Beach licenses are capped at 30% of that neighborhood’s housing stock — and as of 2026, zero are available. The waitlist is effectively closed.
If you already hold a licensed Mission Beach property, you’re sitting on a genuinely scarce asset: no new competition can enter the market. If you’re buying in Mission Beach without a license already attached, plan on a different strategy (see the mid-term rental note below).
Tier Comparison at a Glance
| Tier | Use | Residency Required | Cap | Fee (2 years) |
|---|---|---|---|---|
| Tier 1 | Up to 20 days/yr, whole home or home share | No | None | $226 |
| Tier 2 | Room or whole home (up to 90 days), >20 days/yr | Yes, 275+ days/yr | None | $317 |
| Tier 3 | Whole home >20 days/yr, outside Mission Beach | No | 1% of housing stock (~800 left, Sep 2026) | $1,170 |
| Tier 4 | Whole home >20 days/yr, Mission Beach | No | 30% of Mission Beach (0 left) | $1,170 |
Fees per the City Council fee schedule effective March 1, 2025, still current in 2026. Availability changes — always confirm with the city before applying or buying.
What You Need Before You Apply
The city won’t even process a short-term rental application until you have the prerequisites lined up. Each property needs its own license — you can’t share one across multiple homes. In practice, applications require:
- Proof of ownership of the property
- A floor plan of the rental
- Local emergency contact information for guests and neighbors
- Your transient occupancy tax (TOT) and Tourism Marketing District (TMD) accounts open and current — the city requires these before it will process the STRO application, and you’ll need to collect and remit TOT on every stay going forward
- Your license number displayed in every listing, on every platform
Processing takes several weeks, longer during peak renewal periods. Don’t take bookings on the strength of a submitted application — wait for the license to be issued.
One more structural point that trips people up: STRO licenses are not transferable. If you sell a licensed property, the license doesn’t go with it — the buyer must apply for their own. With Tier 3 licenses capped and dwindling, this makes license status a genuine factor in a property’s value and a key piece of due diligence before you buy.
City of San Diego vs. San Diego County: They’re Different Systems
A frequent source of confusion: the City of San Diego’s STRO program only applies inside city limits. Properties in unincorporated San Diego County — and in separate cities like Carlsbad, Encinitas, and Oceanside — follow entirely different rules.
In unincorporated county areas, there’s no license at all — just a free registration with the Treasurer-Tax Collector’s online portal (you’ll need your deed, and the county asks you to allow up to 30 days for review and to re-register every July). Don’t assume city rules apply just because the address says “San Diego” — check the jurisdiction first. We’ve seen investors model city-tier revenue on county properties and vice versa, and the math doesn’t transfer.
Three Owner Mistakes We See Most Often
1. Buying a property before checking license availability. This is the expensive one. An investor falls in love with a coastal condo, closes escrow, then learns no Tier 3 licenses are available — or that the Tier 4 license on a Mission Beach property died with the sale. Always verify availability and tier fit before you buy, not after.
2. Assuming a license transfers with the sale. It doesn’t. The seller’s Tier 3 or Tier 4 license evaporates at closing. Factor a fresh application — and the risk of the cap being full — into your purchase timeline.
3. Running a 30-day rental strategy without understanding the line. Rentals of 31 or more consecutive nights are mid-term rentals: no STRO license required, standard landlord-tenant law applies. Many owners who can’t get a Tier 3 license (or are sitting in Mission Beach’s zero-availability zone) run profitable 31-night-minimum furnished rentals to traveling nurses and corporate tenants instead. But the dividing line is exact — advertise 30-night minimums and you’re in STRO territory. And ADUs come with their own restrictions, so verify before listing one.
What About 2027? Expect the Rules to Keep Tightening
The direction of travel is clear: enforcement is automated, platforms are cooperating with the city, caps aren’t expanding, and penalties are serious. Owners who are licensed, compliant, and paying TOT are in a strong position — scarcity is on their side. Owners operating on hope are running out of runway.
If you’re weighing a purchase, renewing a license, or deciding between short-term, mid-term, and long-term strategy for a property, the single highest-value step you can take is a real numbers review: what tier fits, what’s available, what TOT and TMD will cost you, and what net income each strategy produces for your specific address.
Frequently Asked Questions
San Diego’s four tiers are: Tier 1 (part-time, up to 20 rental days a year, no residency required), Tier 2 (home sharing for owners who live in the home at least 275 days a year), Tier 3 (whole-home rentals outside Mission Beach for more than 20 days a year), and Tier 4 (whole-home rentals inside the Mission Beach planning area). Your tier depends on how many nights you rent, whether you live in the property, and where the property is located.
All licenses are valid for two years: Tier 1 costs $226 ($33 application + $193 license fee), Tier 2 costs $317 ($33 + $284), and Tier 3 and Tier 4 each cost $1,170 ($41 + $1,129). Fees follow the City Council fee schedule effective March 1, 2025, still current in 2026.
Tier 3 licenses are capped at 1% of the city’s housing stock, with roughly 800 remaining as of late September 2026 — but that number is shrinking, so always confirm availability with the city before applying or buying. Tier 4 (Mission Beach) licenses are capped at 30% of that neighborhood’s housing stock, and zero were available in 2026 with the waitlist effectively closed.
Each property needs its own license — one can’t be shared across homes. You’ll need proof of ownership, a floor plan of the rental, local emergency contact information, and your transient occupancy tax (TOT) and Tourism Marketing District (TMD) accounts open and current, since the city requires these before it will process your application. Processing takes several weeks, so don’t take bookings until the license is actually issued.
No. STRO licenses are not transferable — the seller’s license ends at closing and the buyer must apply for their own. Because Tier 3 licenses are capped and dwindling, license status is a genuine factor in a property’s value and should be part of your due diligence before buying.
No. The STRO program only applies inside City of San Diego limits. Properties in unincorporated San Diego County need no license at all — just a free registration with the Treasurer-Tax Collector’s online portal, renewed every July — while separate cities like Carlsbad, Encinitas, and Oceanside each run their own rules. Check your jurisdiction first, because city-tier revenue math doesn’t transfer to county properties or vice versa.
