San Diego Short-Term Rental Rules (2026): What Condo Buyers and Investors Need to Know

Published October 23, 2026City figures as of October 9, 2026By USIG

Planning to buy a San Diego condo and rent it by the night? Before you count on that income, two rulebooks apply: the City of San Diego's short-term rental licensing, and your building's HOA rules. Here's what each one says, in plain language, with links to the official sources.

The short version
  • Renting a home for less than one month in the City of San Diego requires a license [1].
  • Whole-home licenses outside Mission Beach (Tier 3) are capped. As of Oct 9, 2026, 802 remained citywide [1].
  • A host can hold only one license, and licenses don't transfer to a buyer [1].
  • Your HOA can lawfully ban rentals of 30 days or less [2].

What counts as a "short-term rental" in San Diego?

The City calls it short-term residential occupancy (STRO): renting a home, or part of one, for less than one month. Since May 1, 2023, operating a STRO without a city license has been unlawful. The rules apply to every dwelling in the City of San Diego regardless of zoning [1].

The numbers that matter (as of October 9, 2026)

LicenseIssuedRemainingFees (application + license)
Tier 1135Unlimited$33 + $193
Tier 22,336Unlimited$33 + $284
Tier 34,859802$41 + $1,129
Tier 41,0990$41 + $1,129

Licenses expire two years after they're issued and can be renewed. Fees are non-refundable [1].

Five rules that surprise investors

  1. Licenses don't come with the property. They aren't transferable between hosts, owners, or units, so a condo that "already has a license" doesn't pass it to you [1].
  2. One host, one license, one unit. A host must be a natural person (not an LLC), may hold only one license at a time, and may operate only one unit at a time [1].
  3. 21 to 89 days a year isn't allowed. More than 20 days of whole-home rental needs a Tier 3 or 4 license, and those must be used at least 90 days a year, with quarterly reports to the City [1].
  4. ADUs are generally off-limits. Accessory dwelling units can't be used for short-term rental, except companion units permitted before October 15, 2017 [1].
  5. Taxes come first. You need an active Transient Occupancy Tax certificate and a paid Rental Unit Business Tax account before you can apply [1].

The HOA layer: what California law allows

For condos, the city license is only half the picture. Under California Civil Code §4741, an HOA generally cannot prohibit or unreasonably restrict owners from renting their units, and cannot cap rentals below 25% of the units. It can, however, adopt and enforce rules that prohibit transient or short-term rentals of 30 days or less [2].

In practice, read the CC&Rs and any rental rules, and ask the HOA for its current rental policy in writing, before you remove contingencies.

How we'd underwrite a San Diego condo

USIG perspective — opinion, not data

Underwrite on a 12-month lease as the base case. Treat short-term income as upside only after (1) the HOA allows it in writing and (2) a license is actually issued to you. If the deal only works at nightly rates, it's a speculation on licensing, not an investment.

A practical checklist before you write an offer:
