How Many Days a Year Can You Rent a San Diego Airbnb, by Tier
San Diego STRO tiers turn on how many nights you rent: 20 or fewer for Tier 1, 90 or more for Tier 3 and 4. Here is the gap between them, and what each…

Most property owners look at the San Diego Short-Term Residential Occupancy (STRO) tiers and try to fit their lifestyle into a category. This approach is backwards. Decide how many nights you want to rent first. The City of San Diego built a system where your desired occupancy dictates your legal path, not the other way around. If you want to rent for a month while you travel, you belong in one bucket. If you want a full-time income, you belong in another.
Figuring out how many days you can rent a San Diego Airbnb means looking at the calendar before the application portal. The logic is simple but rigid. San Diego offers no flexibility once you select a tier. Choose the wrong one and you might find yourself with a vacant property for six months because you hit a cap you never anticipated. This guide frames the licensing decision as a single question about your intended night count.
Start With Your Number of Nights, Not the Tier Name
Stop reading the definitions of Tier 1 through 4 for a moment. Look at your personal schedule or your investment pro forma instead. The STRO ordinance is a filter. It sorts owners based on their actual usage. Many owners make the mistake of applying for a Tier 3 license because they want the most permissions, only to realize they only plan to rent for 30 days total. That is a waste of money and resources. A license runs two years and is not transferable, so the tier you pick is a commitment rather than a setting you adjust.
Atlia handles end-to-end operations for owners to help them meet their goals. If you want to rent for 365 days, you have a specific path. If you only want to cover your property taxes by renting for two weeks in July, the path is different. Start with the number. The tier is just the paperwork that follows that decision. You must be precise. The difference between 20 nights and 21 nights is not just one day. It is the difference between a $226 permit and a potential $1,170 permit that might not even be available in your neighborhood.
Many hosts fail to account for the impact of San Diego short-term rental property management on their tier choice. If you are hiring a manager, their fee structure affects how many nights you need to rent to stay profitable. At Atlia the management fee is a flat 10% of booking revenue, and repairs and property supplies are owner costs passed through at cost. Whatever you are paying, work it out as a number before you choose a tier: determine your target revenue, subtract the management fee, and then look at which tier accommodates that volume. A tier you cannot fill profitably is the wrong tier.
Tier 1: 20 Days or Fewer a Year
Tier 1 is for the occasional host. This license is designed for residents who leave town for a specific event or a short vacation. The limit is exactly 20 days per calendar year. You can rent the whole home or just a room. The primary advantage is cost and ease. The cost is $33 for the application plus $193 for the license, $226 in total, for a two-year term. The host does not have to be onsite during the stay, which makes Tier 1 workable for owners who mostly use the property themselves and want to offset costs during high-demand periods.
Twenty days is a hard ceiling. Once you hit day 21, you are in violation of the ordinance unless you hold a higher tier license. If you intend to rent for even one day more, Tier 1 is not the correct vehicle for your property. It is a tool for supplemental income, not a business model.
Owners who use Tier 1 often find that self managing vs full service Airbnb management San Diego is a difficult choice for such a small number of days. It is hard to find a manager willing to take on a 20-day-a-year client. Atlia provides end-to-end management that can help Tier 1 owners get the most revenue out of those few days. By using professional pricing and local operators to handle the few turnovers required, you keep your 20 days as profitable as possible without spending your own vacation time answering guest messages.
Tier 2: More Than 20 Days, but Only If You Live There
Tier 2 is the Home Sharing license. This is a home-share category for owners who maintain the property as their primary residence and host for more than 20 days per calendar year. The specifics are what matter here. The unit has to be your permanent residence and you have to reside there at least 275 days a year. Whole-home rental is allowed, but only for up to 90 days a year; the rest of your hosting is room rental while you are living there. Tier 2 is not capped, so availability is not the constraint. Your own occupancy is.
This tier suits people with a spare bedroom who want to host year round. It is not for investors who do not live on site. Atlia helps Tier 2 hosts by coordinating the high volume of turnovers that come with year-round room rentals. The local operator handles guests so the resident owner does not have to act as a full-time concierge in their own home.
The fee for Tier 2 is $33 for the application plus $284 for the license, $317 in total, for a two-year term. While that is affordable, the compliance burden is higher. You must follow all San Diego STRO permit requirements, including keeping your local contact information updated. Even if you live on the property, you still need a designated contact who can respond to issues within one hour if you are unavailable. Atlia fulfills this requirement for our clients, providing a local professional to manage guest interactions and emergency maintenance coordination.
The Gap: 21 to 89 Nights as a Whole Home
This is the no-man's-land of San Diego rentals. If you own a second home and want to rent it as a whole unit for more than 20 days, but you do not want a full-time rental, you face a real problem. Tier 1 caps you at 20 days. Tier 3 and Tier 4 run the other way: both REQUIRE at least 90 days of licensed use a year. So the tiers do not meet in the middle. A plan to rent a whole home for 45 nights sits above the Tier 1 ceiling and below the Tier 3 floor, and fits no tier as the city defines them. If that is your plan, take it to the City Treasurer before you apply rather than guessing which way it resolves.
This gap creates a major headache for owners who travel for part of the year. They are forced to either leave the home empty after 20 days or compete for a limited Tier 3 license. Many owners choose to move toward longer stays instead. The licensing trigger is renting for less than one month, measured by CALENDAR month rather than by a fixed number of nights, so January 31 to February 28 counts as a month while February 1 to February 28 does not. Owners in this gap often aim for stays that clear that calendar-month test for the remainder of their window. This strategy requires a different approach to pricing and guest management than traditional short stays.
If you find yourself in this gap, it is worth working out your real all-in management fee before deciding whether a Tier 3 license is financially viable. If you only rent for 60 days, the $1,170 license fee eats a large portion of your profit. By reducing your management fee to 10% with Atlia, you can absorb that license cost more easily. Otherwise, you are stuck under the 20-day cap, leaving potential revenue on the table during the most profitable months of the year.
Tier 3 and Tier 4: 90 Days or More, and Where Your Property Sits
Tier 3 and Tier 4 are the Whole Home licenses for properties that are not primary residences. Tier 3 covers the entire city except for Mission Beach. Tier 4 is exclusive to Mission Beach. Both REQUIRE at least 90 days of licensed use a year, and both carry a two-consecutive-night minimum per guest and quarterly reporting. That 90-day floor is the part owners miss: these are not licenses you hold lightly for an occasional booking. The distinction between them is the cap. Tier 3 is capped at 1% of housing units outside the Mission Beach community planning area, and Tier 3 licenses remain available.
Tier 4 is tighter. It is capped at 30% of the housing units in the Mission Beach community planning area, and the Mission Beach Tier 4 cap is currently full. If you buy in Mission Beach today there is no open path to a new whole-home license. Tier 3 and Tier 4 both cost $41 for the application plus $1,129 for the license, $1,170 in total, for two years.
Owners with Tier 3 or Tier 4 licenses are running full-scale hospitality businesses. The operational demands are high. Atlia coordinates all guests, cleaners, and maintenance for these properties. We use local on-the-ground operators to keep turnovers handled professionally. When you are renting for 90 days or more, the frequency of guest communication increases significantly. Our end-to-end management covers issue resolution and pricing for the nights your tier allows.
License Costs, Two-Year Terms, and What You Can't Transfer
A San Diego STRO license is not a permanent right. It is a two-year permit. When the term ends, you must renew and pay the fee again. These fees vary by tier. Tier 1 is $226, Tier 2 is $317, and Tier 3 and Tier 4 are $1,170, each covering the two-year term. If you apply for a Tier 3 license and only use it for three months, you still pay the full $1,170. That makes your choice of night count a major factor in your annual ROI.
The most important rule is that the license stays with the owner, not the property. If you sell your house, the license does not transfer to the buyer. The new owner must apply for their own license. This is a detail investors looking at turnkey listings often miss. Just because a house has an active Airbnb today does not mean you can host guests the day after closing. You must also follow the San Diego STRO local contact requirements, which name a designated contact who responds to a reported complaint within one hour.
Atlia acts as this local contact for all our managed properties. We coordinate vendors and handle urgent property issues as they arise. The obligation is to RESPOND to a reported complaint, in person or by phone, within the hour and then take action to resolve it; responding in time but not stopping the nuisance is a separate reportable violation. A third alleged violation of the host operating requirements at the same unit, or by the same host, within 12 months can go to a hearing officer who may revoke the license. Professional management is the most reliable way to prevent those violations. We handle the daily operations and provide transparent reporting so you know your license is secure.
What to Do Before You Pick a Number
Before you commit to a number of nights, check your zoning and your HOA. An STRO license from the city does not override a private HOA ban on short-term rentals. If your HOA prohibits stays under 30 days, the city license is useless. You should also calculate your San Diego transient occupancy tax liability. As of May 2025, rates are tiered based on proximity to the convention center. Most vacation rentals will fall into the 11.75%, 12.75%, or 13.75% brackets. This tax comes off the top of your revenue and is a major expense.
Compare those costs to your management fees. If you are paying a high management fee and the city occupancy tax, your gross revenue is significantly reduced before you pay for cleaning or utilities. This is why many owners are looking for Evolve vacation rental alternatives in San Diego that offer more value. Atlia provides full-service management for a 10% fee, which improves your net yield. That lower fee might be what makes a Tier 3 license profitable for your property.
Finally, verify the availability of your desired tier. If you are in Mission Beach and want to rent for 100 days, there is no Tier 4 license to be had right now. That leaves 20 days under Tier 1, or stays long enough to clear the calendar-month test. Always check the city's current license position before making an investment based on short-term rental income. Property owners should review these numbers and develop a strategy that stays within legal limits while getting the most out of their property's potential.

Frequently asked questions
Questions owners ask
How many days can you rent a San Diego Airbnb without an STRO license?
None, if the stay is short. San Diego requires an STRO license for any rental of less than one month, and the city measures that by CALENDAR month rather than by a fixed night count. January 31 to February 28 counts as a month; February 1 to February 28 does not. Longer stays fall outside the STRO rules but are subject to different tax and tenancy law.
Can I switch from Tier 1 to Tier 3 if I want to rent more days?
Not automatically. You apply for a Tier 3 license and pay its fee, $41 for the application plus $1,129 for the license, $1,170 in total for the two-year term. Tier 3 is capped at 1% of housing units outside the Mission Beach community planning area, so availability is a real constraint. Note also that Tier 3 requires at least 90 days of licensed use a year, so it is not a way to cover a 40-night plan.
Is there a limit on how many Tier 3 licenses one owner can have?
Yes. A host may hold one license, for one dwelling unit, at a time. If you own several properties you have to decide which one carries the short-term license. The license is also non-transferable and runs with the host rather than the property, so it cannot be sold on or passed to a buyer with the home.
Does the 20 day limit for Tier 1 include the days I live in the house?
No. Tier 1 is an aggregate of 20 days or less per year of short-term rental, and the days you occupy the home yourself are not part of that count. The host does not need to be onsite during a Tier 1 stay. Check how the city counts a stay that spans a date boundary with the City Treasurer rather than assuming, because the 20 days is a hard ceiling.
