San Diego STRO License: The Complete 2026 Guide

A San Diego STRO license is the official permit required to legally operate any short-term residential occupancy in the City of San Diego. Specifically, any rental of a dwelling unit or portion thereof for fewer than 31 consecutive nights requires a valid STRO license under San Diego Municipal Code Chapter 5, Article 10, Division 1. Operating without one has been unlawful since May 1, 2023, and fines reach $1,000 per day. At West Coast Homestays, we guide property owners across San Diego, Encinitas, Carlsbad, La Jolla, Oceanside, Mission Beach, and Pacific Beach through this exact process every season, and the questions we field most often come from hosts who did not realize how much the tier structure changes their earning strategy.

TL;DR: San Diego STRO License at a Glance

• San Diego's STRO ordinance covers all 9 City Council Districts; operating without a license since May 1, 2023 can trigger fines of up to $1,000 per day.

• Four tiers exist: Tier 1 (part-time, up to 20 nights/year), Tier 2 (home-sharing with host onsite), Tier 3 (whole-home, citywide cap of 1% of housing units), and Tier 4 (Mission Beach whole-home, capped at 30% of Mission Beach CPA units).

• As of May 2026, Tier 3 has 829 licenses remaining before the cap; Tier 4 is fully closed and requires a lottery for any new opening.

• License fees as of March 2026 range from $226 total for Tier 1 to $1,170 total for Tier 3 and Tier 4. All fees are non-refundable and renewal fees match initial fees.

• Before applying, you need an active Transient Occupancy Tax (TOT) Certificate and a paid Rental Unit Business Tax (RUBT) account. LLCs, corporations, and trusts cannot hold a license; the holder must be a natural person.

• According to Airbtics' 2026 data snapshot, San Diego short-term rentals generated a median of roughly $67,000 in annual revenue at about 71% occupancy, confirming that a licensed STR in the right tier is a materially valuable asset.

San Diego's short-term rental landscape shifted decisively when the STRO ordinance took full effect in 2023. The City capped Tier 3 permits at roughly 1% of the city's total housing stock and Tier 4 (Mission Beach) at 30% of that community planning area's units, creating real scarcity. According to the City of San Diego's Active STRO Licenses Open Data Portal, updated as recently as June 2026, a total of 8,384 licenses had been issued across all tiers. Tier 3, the most commercially significant category for whole-home operators, shows only 829 slots remaining before the cap is reached.

For property owners, the practical implication is this: a Tier 3 or Tier 4 license is a finite asset. Neighborhoods like Pacific Beach and Mission Beach draw guests who pay premium nightly rates, and licensing those properties correctly is the first step toward capturing that revenue. The four-tier system shapes everything from what you can charge, how often you can rent, and whether you need to be present. Getting the tier wrong is not just a compliance problem; it is a revenue strategy problem.

This guide covers every component of the STRO license process in 2026: the four tiers and their rules, the prerequisites you need before applying, the step-by-step application process, current fees, the cap and lottery mechanics, ongoing compliance obligations, and the practical questions we see property owners wrestle with that most official resources do not address.

What Is a San Diego STRO License and Who Needs One?

A San Diego STRO license is a permit issued by the City of San Diego's Office of the City Treasurer that authorizes a property owner or host to rent a dwelling unit for short-term residential occupancy, defined as any rental lasting fewer than 31 consecutive nights. The STRO ordinance applies citywide across all nine Council Districts and all zoning designations. If your property is within City of San Diego limits, the ordinance covers you. You can verify your district using the City of San Diego Council District Map.

The ordinance covers any rental of a dwelling unit or part of one. Renting a single spare bedroom to guests for three nights counts. Renting an entire beachfront property in Pacific Beach for two weeks counts. The only exclusion is stays of 31 nights or longer, which fall outside the ordinance entirely. That is why mid-term rentals (31 or more nights) have become a strategically important alternative for San Diego owners navigating the cap system, a point we return to later.

Specifically, platforms including Airbnb, VRBO, and Booking.com are legally required not to process transactions for unlicensed properties. The City also operates a 24-hour STR hotline at 619-236-5500 where neighbors can report suspected unlicensed operations. Three substantiated complaints within a 12-month period can trigger license suspension proceedings. The enforcement infrastructure is real and active.

One natural person must hold the license. LLCs, corporations, and trusts are expressly ineligible. A host may hold only one STRO license at a time and may not operate more than one dwelling unit for short-term rental simultaneously under that license. Licenses are also non-transferable: they do not follow a property to a new owner and cannot be moved to a different address.

What Are the Four STRO License Tiers in San Diego?

San Diego's STRO license system is organized into four distinct tiers, each with specific rules governing how many nights you can rent per year, whether the host must be present, and whether the property qualifies as a whole-home rental or a room-share. The tier you fall into determines your compliance obligations, your annual fee, and in the case of Tiers 3 and 4, whether a license slot is even available.

Tier	Type	Annual Rental Days	Host Onsite Required?	Cap	App + License Fee (2026)
Tier 1	Part-Time	20 days or fewer	No	None	$33 + $193 = $226
Tier 2	Home Sharing	More than 20 days	Yes (must reside onsite)	None	$33 + $284 = $317
Tier 3	Whole Home (non-Mission Beach)	More than 20 days	No (absent up to 90 days/year)	1% of citywide housing units (829 remaining as of May 2026)	$41 + $1,129 = $1,170
Tier 4	Whole Home (Mission Beach CPA only)	More than 20 days	No (absent up to 90 days/year)	30% of Mission Beach CPA housing units (0 remaining as of May 2026)	$41 + $1,129 = $1,170

Tier 1: Part-Time Hosting

Tier 1 is designed for owners who want to occasionally rent their home, up to 20 nights per year total. No onsite host presence is required, there is no cap on the number of Tier 1 licenses issued, and the annual cost is $226. This tier suits property owners who travel seasonally and want to offset costs during their absence, but it is not a viable model for anyone pursuing meaningful rental income.

Tier 2: Home Sharing

Tier 2 allows rentals beyond 20 nights per year, but the host must physically reside in the dwelling unit during guest stays. Renting a room while you sleep in the master bedroom qualifies. Tier 2 carries no citywide cap, costs $317 to initiate, and works well for owner-occupants in Pacific Beach, North Park, or any other San Diego neighborhood where the owner is present. It does not work for absentee investors.

Tier 3: Whole Home (Non-Mission Beach)

Tier 3 is the license most San Diego investment property owners are pursuing. It allows whole-home rentals for more than 20 nights per year anywhere in the city outside the Mission Beach Community Planning Area, with the host permitted to be absent for up to 90 days per calendar year. The minimum stay for Tier 3 guests is two nights. This tier is subject to the 1% citywide housing unit cap, calculated using SANDAG Demographic and Socioeconomic Housing estimates last updated March 2026. As of May 2026, 4,777 Tier 3 licenses have been issued and 829 slots remain.

Tier 4: Mission Beach Whole Home

Tier 4 mirrors Tier 3 rules but applies exclusively to properties within the Mission Beach Community Planning Area. The cap is set at 30% of Mission Beach CPA housing units. As of May 2026, the cap has been reached and no new Tier 4 licenses are available through standard application. Tier 4 applications reopened briefly from July 1 through August 15, 2026, after being closed since November 2022. Any new Tier 4 openings require a lottery, which the City administers under Municipal Code section 510.0106(c). Use the City of San Diego Community Planning Area (CPA) Map to confirm whether your property falls within the Mission Beach CPA boundary.

Does San Diego Allow STR Operations, and What Are the Rules?

San Diego does allow short-term rentals, but specifically within the licensed framework established by the STRO ordinance, which took full effect on May 1, 2023. San Diego is one of the few major California coastal cities that has created a functional licensing pathway rather than a near-total ban, though the permit caps for Tier 3 and Tier 4 are reducing the total number of operating STRs over time. The City estimated that the cap structure would cut the number of active STRs in San Diego nearly in half from pre-ordinance levels.

All licensed hosts must comply with the STRO Good Neighbor Policy, which covers noise limits, parking, trash, and general nuisance standards. Occupancy limits are standardized at two guests per bedroom plus two additional guests, and exceeding the posted occupancy is an enforceable violation. Your STRO license number must appear on every listing across Airbnb, VRBO, Booking.com, and any other platform where the property is advertised.

Tier 3 and Tier 4 license holders face additional requirements that Tier 1 and Tier 2 hosts do not. Specifically, whole-home operators must use the license for a minimum of 90 rental days per year under STRO Ordinance section 510.0107(c), and they must submit quarterly reports to the City. Report deadlines are April 30 (Q1), July 31 (Q2), October 31 (Q3), and January 31 (Q4). The official City video on submitting quarterly reports walks through the submission process in detail.

Hosts in all tiers are also required to display human trafficking awareness information on the property. This is a state and local compliance requirement, and the San Diego County District Attorney's office provides the reference materials the City directs hosts toward.

How Do You Apply for a San Diego STRO License?

Applying for a San Diego STRO license is a sequential process that starts with two mandatory prerequisites and ends with submitting an application through the City's online portal. The full process typically takes a few weeks from submission to license issuance if all documentation is in order, but incomplete applications or outstanding compliance issues can extend that timeline significantly.

Step 1: Obtain an Active TOT Certificate

Every STRO applicant must first hold an active Transient Occupancy Tax (TOT) Certificate issued by the City of San Diego. TOT is the hotel-style occupancy tax San Diego collects on short-term stays. Apply through the Transient Occupancy Tax Online Registration System. If you already have a TOT certificate from a previous rental but are unsure of your number, the OpenData TOT Certificate Number Lookup can retrieve it.

Step 2: Activate and Pay Your RUBT Account

An active and paid Rental Unit Business Tax (RUBT) account is the second prerequisite. RUBT is a separate business tax the City charges rental property operators. Verify your account status using the OpenData Rental Unit Business Tax Account Lookup. If the account shows unpaid, clear the balance before proceeding. An outstanding RUBT balance is one of the most common reasons STRO applications are delayed or denied.

Step 3: Check for Code Enforcement Complaints

Before submitting, check whether any code enforcement complaints are on file against your address using the Check Code Enforcement Complaints portal. Outstanding complaints, particularly for prior unpermitted STR operation, can result in application denial. Resolving these before applying saves significant time.

Step 4: Gather Required Documentation

For owner-occupants applying under their own name, the TOT certificate and RUBT account number are the core requirements. If the host is not the property owner (for example, a tenant who has permission to sublease), additional documentation is required: a Business Tax Certificate and a Right to Occupy Document. The Right to Occupy Document must demonstrate that the host can legally occupy the dwelling unit and sublease for fewer than one month. A lease agreement with an explicit STRO subletting clause qualifies, as does a written statement signed by both the property owner and the host.

Step 5: Submit the Application Online

Applications are submitted through the City of San Diego STRO License Application Portal (Accela). The portal walks you through uploading your documentation, selecting your tier, and paying the non-refundable application fee. For a video walkthrough, the STRO License Application Video from the City of San Diego covers the submission process step by step.

Step 6: Post Your License Number

Once your license is issued, the number must appear on all advertising, including your Airbnb, VRBO, and Booking.com listings, before you take any bookings. Licenses expire two years from issuance. The City emails renewal notices 60 days before expiration, and renewal fees are identical to initial fees.

For direct questions about the application, contact the STRO Administration office at 619-615-6120 or stro@sandiego.gov.

What About Neighboring Jurisdictions: Encinitas, Carlsbad, Oceanside, and La Jolla?

The San Diego STRO ordinance applies only to properties within the official City of San Diego boundaries. Properties in Encinitas, Carlsbad, and Oceanside are governed by separate municipal codes with their own permit requirements, fee structures, and cap rules. La Jolla is a community within the City of San Diego, so properties there fall under the standard STRO framework described above and are most commonly subject to Tier 3 licensing.

This distinction matters a great deal to property owners managing assets across North County San Diego. A Carlsbad property near the Village or the Flower Fields does not need a City of San Diego STRO license; it requires whatever permit Carlsbad's own municipal code mandates. Similarly, an Encinitas property near Moonlight Beach operates under Encinitas city rules, not San Diego's tier structure.

At West Coast Homestays, we manage properties across all these markets, and the compliance picture differs meaningfully by city. Carlsbad, Encinitas, and Oceanside each have their own registration processes, tax obligations, and operating restrictions. If you own a rental in any of these jurisdictions, confirm the applicable local rules with that city's planning or finance department before assuming the San Diego STRO framework applies.

For properties in unincorporated San Diego County, such as certain inland communities outside any city boundary, the County of San Diego's own short-term rental ordinance governs. The City of San Diego's STRO rules have no jurisdiction there. Our San Diego property management resource hub covers compliance considerations across these different jurisdictions in more detail.

What Does the Tier 3 Cap Mean for Your Revenue Strategy?

The Tier 3 cap represents one of the most consequential structural features of San Diego's STRO system from a revenue and investment strategy perspective. With only 829 Tier 3 slots remaining citywide as of May 2026, a whole-home short-term rental license outside Mission Beach has become a genuinely scarce permit. Properties holding active Tier 3 licenses are operating a licensed asset that carries meaningful value beyond the physical property itself.

For property owners who have not yet secured a Tier 3 license, the window is narrowing. According to the City of San Diego STRO Official Page, the cap is calculated based on SANDAG housing estimates, and as demand for licenses continues, the remaining 829 slots will not last indefinitely. If you own a San Diego investment property that qualifies for Tier 3 and you have not applied, the cost of delay is real: every month without a license is a month of lost short-term rental income.

The revenue context is significant. According to Airbtics' 2026 Airbnb data snapshot, San Diego short-term rentals generated a median of roughly $67,000 in annual revenue at approximately 71% occupancy over the 12 months ending January 2026. That median figure covers the full range of San Diego properties; a well-positioned coastal property in Pacific Beach or La Jolla with professional revenue management can substantially exceed it.

For properties that cannot access Tier 3 or where the cap has been reached in a specific neighborhood, mid-term rentals of 31 nights or more offer a legally clean alternative. Mid-term stays fall entirely outside the STRO ordinance, requiring no STRO license while still generating consistent income. A hybrid short-term and mid-term strategy, where peak-season weeks run as STR and off-season months convert to 30-plus-day rentals, can outperform a pure STR model on annual revenue. Based on portfolio data from properties West Coast Homestays manages, a well-calibrated hybrid strategy has produced $136,732 in annual revenue on a property that a pure STR model projected at $98,800. That is not a marginal difference. It reflects what thoughtful tier and revenue strategy actually looks like in practice.

What Are the Practical Challenges Nobody Warns You About?

Most official guides cover the rules accurately but leave out the operational details that determine whether your application succeeds smoothly or drags on for weeks. Here are the issues we see most often when property owners in our markets navigate the STRO process.

LLC and Trust Ownership: The Workaround Question

The STRO ordinance requires the license holder to be a natural person. LLCs, corporations, and trusts cannot hold a license. This trips up investors who purchased their San Diego property inside an LLC for liability protection. The license must be held in the name of an individual, typically the person who has the legal right to occupy the unit and sublease it. If the LLC is the property owner, the individual host will need a Right to Occupy Document signed by an authorized representative of the LLC confirming the host's right to sublease for short-term periods.

This is not a legal workaround that eliminates the LLC structure; it is a documentation step that satisfies the City's natural-person requirement while the property remains LLC-owned. Consult your real estate attorney on how to structure the right-to-occupy agreement correctly for your specific ownership situation.

Application Delays: What Actually Causes Them

Incomplete TOT registration is the most common delay trigger we observe. Many first-time applicants assume their Airbnb registration with the platform substitutes for a City TOT Certificate; it does not. TOT and RUBT must be independently registered with the City before the STRO application portal will accept a complete submission. Outstanding code enforcement complaints are the second most common cause of delay or outright denial. Checking the code enforcement portal before applying takes five minutes and can save weeks.

The Tier 3 Quarterly Reporting Requirement

Tier 3 and Tier 4 hosts often overlook the ongoing quarterly reporting obligation until they miss a deadline. Reports are due four times per year, and failing to submit them is a compliance violation that can jeopardize your license at renewal. The City publishes a clear due date structure: April 30, July 31, October 31, and January 31. Put these on a recurring calendar alert the day your license is issued. The STRO Host Requirements Video from the City of San Diego covers the full set of ongoing obligations for license holders.

The 90-Day Minimum Use Requirement

Tier 3 and Tier 4 license holders must actively use the license for at least 90 rental days per year. This minimum is stated in STRO Ordinance section 510.0107(c). Property owners who acquire a Tier 3 license but then convert the property to long-term rental or leave it vacant risk failing this threshold and losing the license at renewal. If you are considering converting your STR to a mid-term or long-term rental, make sure you understand how that decision interacts with the 90-day use minimum before making the switch.

How the Tier 4 Lottery Actually Works

When Mission Beach Tier 4 applications open (as they did briefly from July 1 through August 15, 2026), the City collects applications and then conducts a random lottery to determine processing order, per Municipal Code section 510.0106(c). There is no "good actor" fast-track in the current lottery structure for new applicants, although the San Diego Short-Term Rental Alliance (San Diego STRA) has submitted formal memos to the City advocating for good actor prioritization. Applicants who submit during an open window are placed in a random queue, not a first-come-first-served line. Monitoring the City's official STRO page for future Tier 4 opening announcements is the only way to catch the next window.

What Are the Enforcement Consequences for Non-Compliance?

San Diego's STRO enforcement structure carries real financial consequences. Operating a short-term rental without a valid license exposes a host to fines of up to $1,000 per day. Airbnb, VRBO, and Booking.com are legally obligated under the ordinance to remove listings that do not display a valid STRO license number, which means an unlicensed property risks both the fine and the permanent platform delisting.

Neighbor complaints are routed through the City's 24-hour STR hotline at 619-236-5500 and through the online STRO Violation reporting portal. Three substantiated complaints within a 12-month period can initiate license suspension proceedings. The Building and Land Use Enforcement (BLUE) team handles investigation and enforcement; their direct contact is 619-533-6489 or dsdstrocomplaint@sandiego.gov.

The most common substantiated complaints involve noise, parking, and occupancy violations. Keeping guests within the two-per-bedroom-plus-two rule, managing check-in noise after 10 p.m., and ensuring guests understand parking rules are the three most practical steps licensed hosts can take to stay below the complaint threshold. The STRO Good Neighbor Policy is the reference document every licensed host should post visibly inside the property.

For owners managing multiple properties or trying to keep compliance details straight across a portfolio, our STR laws and regulations resource section provides ongoing coverage of rule changes and enforcement updates across San Diego's coastal neighborhoods.

Frequently Asked Questions About the San Diego STRO License

Does San Diego allow short-term rentals (STR)?

Yes, San Diego allows short-term rentals under the STRO ordinance that took full effect on May 1, 2023. All rentals lasting fewer than 31 consecutive nights require a valid STRO license from the City's Office of the City Treasurer. The ordinance covers all nine City Council Districts across all zoning designations. Operating without a license since that date can result in fines of up to $1,000 per day, and platforms like Airbnb and VRBO are required to remove unlicensed listings.

Do you need a license to manage short-term rentals in California?

In California, the requirement varies by jurisdiction. In San Diego specifically, the individual host (a natural person, not an LLC or trust) must hold a valid STRO license to legally operate any rental under 31 nights. Professional property managers who manage licensed STRs on behalf of hosts do not hold the license themselves; the host holds it. Managers who are not the licensed host cannot operate the property without the host's valid license in place. Some cities in California require managers to hold a California Department of Real Estate license for certain management activities, so verifying both the city-level and state-level requirements before launching any management operation is the right starting point.

What are the STRO license fees in San Diego for 2026?

As of March 2026, San Diego STRO license fees are: Tier 1 costs $33 (application) plus $193 (license) for a total of $226; Tier 2 costs $33 plus $284 for a total of $317; Tier 3 costs $41 plus $1,129 for a total of $1,170; Tier 4 costs $41 plus $1,129 for a total of $1,170. Licenses are valid for two years and renewal fees are identical to initial fees. All fees are non-refundable regardless of whether the license is approved or denied.

How many Tier 3 STRO licenses are left in San Diego?

As of May 2026, the City of San Diego had issued 4,777 Tier 3 licenses with 829 slots remaining before the citywide cap (set at 1% of San Diego's total housing units per SANDAG estimates) is reached. Tier 4 (Mission Beach) had reached its 30% cap with zero slots available. Tier 1 and Tier 2 have no cap. Owners pursuing Tier 3 should apply as soon as prerequisites are in order; the remaining slots represent a finite window. Check current counts on the Active STRO Licenses Open Data Portal.

Can an LLC hold a San Diego STRO license?

No. The STRO ordinance requires the license holder to be a natural person. LLCs, corporations, and trusts are ineligible. If a property is owned by an LLC, the individual host can still obtain a license by providing a Right to Occupy Document, which is a signed agreement from the LLC authorizing the individual to occupy the dwelling and sublease it for short-term stays. This document, combined with an active TOT Certificate and RUBT account, satisfies the City's application requirements while leaving the underlying LLC ownership structure intact.

What is the minimum stay for Tier 3 and Tier 4 STRO license holders in San Diego?

Tier 3 and Tier 4 license holders are required to enforce a two-night minimum stay for guests. This minimum is set by the STRO ordinance and is not negotiable at the individual host level. Additionally, Tier 3 and Tier 4 hosts must use the license for a minimum of 90 rental days per year to maintain compliance under STRO Ordinance section 510.0107(c), and must submit quarterly reports to the City four times per year.

What contact information does the City provide for STRO questions?

The City of San Diego has dedicated contacts for different STRO-related matters. For general STRO administration: 619-615-6120 or stro@sandiego.gov. For TOT administration: 619-615-1530 or sdtot@sandiego.gov. For RUBT administration: 619-615-1545 or rtax@sandiego.gov. For enforcement complaints: 619-533-6489 or dsdstrocomplaint@sandiego.gov. The 24-hour STR complaint hotline for neighbors is 619-236-5500. Having these contacts on hand before and after you apply is practical and prevents avoidable delays.

What Should San Diego STR Owners Do Next?

Navigating the STRO license process in 2026 requires understanding which tier fits your property, verifying your prerequisites, and moving quickly if you are targeting Tier 3 before the cap closes. The license itself is straightforward once documentation is in order. The harder questions are the ones that follow: which tier maximizes your revenue given your ownership structure, how a mid-term rental strategy fills the gaps a capped or unavailable STR license creates, and how to stay compliant quarter after quarter without it consuming your time.

San Diego short-term rentals generated a median of roughly $67,000 in annual revenue per Airbtics' 2026 data, at about 71% occupancy. But median figures mask the full range. Properties in La Jolla, Pacific Beach, and Mission Beach that run optimized listings with professional revenue management consistently outperform that figure. The license gets you into the market. What you do with it determines what you actually earn.

The key actions from this guide, in order: confirm your Council District and CPA to determine your tier, check for outstanding TOT and RUBT issues, resolve any code enforcement complaints, gather your Right to Occupy documentation if needed, and submit your application through the Accela portal before Tier 3 availability closes further. For Tier 4, monitor the City's official STRO page for future lottery windows.
