San Diego short-term rental rules for a condo come from two places at once. The HOA's CC&Rs and house rules can limit or ban rentals below a set length, and the City of San Diego requires a license for any stay under one month. You need a yes from both before you count on Airbnb income.
At Triolo Realty, Darin Triolo helps buyers compare what a listing implies with what the CC&Rs and the city actually allow.
Who sets the short-term rental rules for a San Diego condo?
Two rulebooks decide whether you can rent a City of San Diego condo by the night: the HOA's governing documents and the city's short-term residential occupancy (STRO) ordinance. California law sits behind both and limits how far HOA rental rules can reach.
| Rule source | What it controls | Where to find it |
|---|---|---|
| HOA documents (CC&Rs, bylaws, house rules) | Whether owners may rent, minimum lease length, guest rules, fines | The seller's HOA document package or the HOA manager |
| City of San Diego STRO ordinance | Licenses for stays under one month, tiers, caps, minimum stays | sandiego.gov/stro and Municipal Code Chapter 5, Article 10 |
| California HOA law | How far an HOA can restrict rentals | A real estate attorney |
The city's STRO pages and ordinance don't mention HOAs or CC&Rs, so treat the license and HOA permission as separate approvals.
What do the CC&Rs and HOA rules say about short-term rentals?
Each HOA writes its own rental rules, so the only reliable answer for a specific building is in that building's CC&Rs, bylaws, house rules and any separate rental policy. Look for:
- A minimum lease term, written in days, months or as a ban on "transient" use
- Whether an owner may rent the whole unit, a single room, or neither
- Registration rules, such as filing each lease with the HOA
- Guest rules for parking and amenities
- Fines for violations
- Proposed amendments that haven't been voted on yet
Then read the board minutes. A rule that's still being debated won't be in the CC&Rs yet. California lets a prospective buyer request the last 12 months of approved board minutes from the seller under Civil Code 4525(a)(10).
Does the City of San Diego require a license for short-term rentals?
Yes. The City of San Diego defines short-term residential occupancy as a stay of less than one month, and it has been unlawful to operate one without a STRO license since May 1, 2023 (City of San Diego STRO page, as of October 2026).
The ordinance (San Diego Municipal Code Chapter 5, Article 10, Division 1) sets four license tiers:
- Tier One covers home sharing or whole-home rentals totaling 20 days or less per calendar year.
- Tier Two covers home sharing for more than 20 days a year in the host's primary residence, which the host must occupy at least 275 days of that year.
- Tier Three covers whole-home rentals for more than 20 days a year outside Mission Beach. It's capped at 1 percent of the city's housing units outside Mission Beach, and the ordinance provides for a lottery.
- Tier Four covers whole-home rentals in Mission Beach, capped at 30 percent of that area's housing units. The city says the Tier Four application period has closed.
Tiers Three and Four also require a two-night minimum stay and at least 90 days of use a year. Every host needs a Transient Occupancy Tax certificate and must show that number and the license number on every ad. Hosts may hold only one license at a time.
For a buyer, the most important line in the ordinance is "Licenses are not transferrable." If the seller hosts with a license, that license doesn't come with the unit. You'd apply in your own name, and whole-home licenses outside Mission Beach come from a capped pool.
Can an HOA in California ban Airbnb?
In many cases, yes. California law (Civil Code section 4741) limits how far an HOA can restrict ordinary longer-term leasing, but it leaves associations room to adopt rules on short-term rentals.
A building can allow 12-month leases and still prohibit three-night stays. How the law applies to one building depends on the wording of its documents and when each rule was adopted (Civil Code section 4740). That's a question for a real estate attorney.
Why don't other Airbnb listings in the building prove anything?
Other listings show what owners are doing. Only the documents show what's allowed, and a few thinking traps make the listings feel like proof anyway.
Social proof is the obvious one. When several units show up on a booking site, the question feels settled. Some of those hosts may be licensed. Others may be breaking the CC&Rs or renting for a month or longer, which falls outside the city's STRO definition.
Survivorship bias hides the rest. You see the listings still running. The owners who were warned or fined and stopped don't show up.
Anchoring can start with the unit's own listing. Listing remarks sometimes put "Airbnb potential" right next to the ocean view. The view comes with the unit. Hosting nightly guests takes permission.
By the spreadsheet stage, a nightly rate from a booking site or a revenue calculator has become the starting point for your budget. An HOA ban, a two-night minimum or a full license pool can push the real figure to zero.
Then there's sunk cost, which shows up in escrow. After you've paid for an inspection and an appraisal, a vague answer from the HOA is easy to talk yourself past. That's one reason to keep your contingencies while you review documents.
The better question: if this unit could never host a nightly guest, would the price still make sense?
Buyers who'd rather not share the elevator with nightly guests can use the same documents, along with the building's owner-occupant versus renter ratio.
What should you ask before you make an offer?
Get the documents early, and have the answers in writing before you remove contingencies. Work through it in this order:
- Ask the listing agent, in writing, whether the HOA allows rentals shorter than one month, and for the section that says so.
- Request the CC&Rs, bylaws, house rules, any rental policy, proposed amendments and 12 months of approved minutes.
- Ask the HOA manager whether owners have been warned or fined over short-term rentals.
- Confirm the building is in the City of San Diego, then check the tier you'd need and current availability on the city's STRO page.
- Ask whether the seller holds a STRO license, knowing it won't transfer to you.
- Fit all of this inside your contingency period, and take open questions to a real estate attorney or tax professional.
Frequently asked questions
Does a San Diego STRO license override my HOA's rules?
A city license and HOA permission are separate questions. The City of San Diego's STRO ordinance governs licensing for stays under one month and doesn't mention HOAs or CC&Rs. An owner can hold a valid city license and still face an HOA rule that limits or bans short stays, so confirm both before counting on rental income.
Does the seller's short-term rental license transfer to the buyer?
No. The City of San Diego's ordinance states that STRO licenses are not transferable, and the City won't accept a request to transfer a license's ownership or location. A buyer who wants to host must apply in their own name, and whole-home licenses outside Mission Beach come from a capped pool.
Is a rental of one month or longer a short-term rental in San Diego?
Not under the City of San Diego's ordinance, which defines short-term residential occupancy as a stay of less than one month. A stay of a month or longer falls outside the STRO license rules. The HOA's CC&Rs may still set a minimum lease term. Check the CC&Rs and house rules for it before signing any lease.
Do the city's short-term rental rules apply in Del Mar or Carlsbad?
The City of San Diego's STRO ordinance applies only inside city limits. Del Mar, Carlsbad and the other cities in San Diego County have their own municipal codes. Check with the city where the building sits. Wherever the property is, the HOA's documents apply on top of local rules.
Can an HOA change its short-term rental rules after I buy?
An HOA's rental policy isn't frozen on the day you close. Owners can amend CC&Rs through the process the documents set out, and boards revise house rules over time. Whether a new restriction applies to an owner who bought earlier depends on California law and the wording of the change, so ask a real estate attorney.
