Airbnb & Short-Term Rental Rules in San Diego (2026 Guide)

Quick Answer

San Diego issues tiered short-term rental licenses, with a license tied to a host's primary residence facing fewer restrictions than a license for a non-primary-residence (investment) property. Non-primary-residence licenses are capped citywide, and when demand has exceeded the cap, the city has used a lottery system to allocate them.

San Diego's short-term rental framework is distinctive for using a hard numeric cap on non-primary-residence licenses, allocated in part through a lottery when demand outpaces supply — a mechanism that makes acquiring an investment-focused license fundamentally less predictable than in cities with no such cap.

License Tiers

San Diego's system generally distinguishes based on primary residence status and rental scope — hosting a room or your whole primary home occasionally faces a different regulatory path than a dedicated, non-owner-occupied investment property used purely for short-term rental income.

The Citywide Cap on Non-Primary-Residence Licenses

Unlike cities that simply prohibit non-owner-occupied short-term rentals outright, San Diego caps the total number of such licenses available citywide. When demand has exceeded that cap, the city has used a lottery process to allocate available licenses — meaning even a fully qualified applicant isn't guaranteed a license if the cap is already reached.

What This Means for Investment Strategy

This cap-and-lottery structure introduces genuine uncertainty for investors specifically targeting San Diego for a dedicated short-term rental property. Unlike a straightforward "yes you can" or "no you can't" rule, success depends on current license availability and, potentially, lottery timing — factors outside the investor's direct control.

Neighborhood-Level Considerations

Certain high-demand and coastal neighborhoods have drawn additional scrutiny given concentrated short-term rental activity, which can affect both the practical experience of operating there and the broader political pressure around future rule changes in those specific areas.

Practical Takeaway

Before buying in San Diego for a non-owner-occupied short-term rental strategy, check current license cap status and whether a lottery or waitlist is active, directly with the City of San Diego's short-term rental licensing office — the cap status changes over time, and buying a property assuming license availability without confirming current capacity carries real risk.

Frequently Asked Questions

Can I get a short-term rental license for an investment property I don't live in?

It's possible but capped -- San Diego limits the total number of non-primary-residence licenses citywide, and when applications have exceeded that cap, the city has used a lottery process to allocate available licenses rather than first-come-first-served.

How does the license tier system work?

Tiers generally distinguish based on whether it's the host's primary residence and how much of the home is being rented -- primary-residence hosting a room or occasionally the whole home faces different (generally less restrictive) treatment than a dedicated non-owner-occupied investment property.

What happens if I want a license but the non-primary-residence cap is full?

You may need to enter a waitlist or lottery process when one is opened, or wait for an existing license to become available -- this makes acquiring a non-primary-residence license less certain than in cities without a hard numeric cap.

Are there geographic restrictions within San Diego beyond the citywide cap?

Some areas, including certain coastal and high-demand neighborhoods, have drawn additional scrutiny and enforcement focus given STR density concerns, on top of the citywide licensing framework.

What are the penalties for operating without a valid license?

Fines apply for unlicensed operation, and the city has worked with platforms to identify and remove unlicensed listings tied to San Diego addresses.
