Vacation Rental Investment in La Jolla, California
Anyone considering a La Jolla purchase partly for short-term rental income needs to understand San Diego's citywide Short-Term Residential Occupancy (STRO) ordinance before running the numbers -- it's a licensed, tiered, and in the whole-home category, effectively capped system, not an open market where any owner can simply list a property. This page lays out the actual tier structure, the tax rate, and what's genuinely uncertain about license availability going forward.
The STRO Ordinance and Its Four License Tiers
San Diego's Short-Term Residential Occupancy ordinance took effect in May 2023 and applies citywide, including all of La Jolla, to any rental of a dwelling unit (or part of one) for stays under one month. It defines four license tiers: Tier 1 covers part-time rentals of up to 20 days per year; Tier 2 covers home-sharing where the host lives on-site; Tier 3 covers whole-home rentals outside Mission Beach; and Tier 4 covers whole-home rentals specifically within Mission Beach. A host may hold only one license at a time and generally may not operate more than one dwelling unit under STRO at once -- this is not a structure built for scaling up a multi-property short-term rental portfolio within city limits.
Tier 3 Is the One That Matters for a Typical La Jolla Investment Purchase -- and It's Nearly Full
For a typical whole-home La Jolla vacation rental, Tier 3 is the relevant category, and it's citywide-capped at roughly 1% of San Diego's total housing units outside Mission Beach. 2026 reporting describes that pool as close to exhausted: one snapshot cited 4,638 Tier 3 licenses issued with 913 remaining, while a later 2026 snapshot cited only 880 remaining as of April 10, 2026 -- consistent, declining figures rather than contradictory ones, both pointing toward a license pool that's filling up. Tier 4 (Mission Beach) is reported as closed to new applications, with a waitlist at zero remaining. This means a buyer counting on being able to obtain a new Tier 3 STRO license as part of a La Jolla investment plan should treat that as genuinely uncertain, not a formality -- confirm current license availability directly with the City of San Diego Treasurer's office before finalizing a purchase decision built around STR income.
La Jolla's Existing Share of the Market
La Jolla already accounts for roughly 9.32% of the city's active STRO licenses among named community planning areas, per 2026 reporting -- a meaningful, above-average concentration for a single community, suggesting La Jolla has historically been a popular and successful short-term rental location even under the newer licensing regime. That existing concentration cuts both ways for a prospective buyer: it's evidence of real, demonstrated visitor demand, but it also means the local share of a citywide, nearly-exhausted license pool may already be relatively saturated.
The Coastal Zone Adds a Layer Most Inland San Diego Rentals Don't Have
Because much of La Jolla sits within the California Coastal Zone, the STRO ordinance itself required California Coastal Commission certification before taking effect -- and properties in the Coastal Zone can face additional layers of review around property modifications and land-use decisions that interact with rental use, beyond the base citywide STRO tier system. This research did not compile a specific, itemized list of Coastal-Zone-specific STR restrictions distinct from the base city ordinance, and none is invented here -- confirm whether a specific La Jolla parcel's Coastal Zone status adds any additional requirement beyond the standard STRO license, directly with the City of San Diego and, if applicable, the California Coastal Commission.
The Tax Line: 11.75% TOT on Top of Any Platform or Management Fee
San Diego voters' 2020 Measure C raised the city's Transient Occupancy Tax (TOT) into three geographic zones tied to distance from the Convention Center, effective May 1, 2025; La Jolla falls in the 11.75% zone (the two zones closer to downtown run 12.75% and 13.75%). The tax applies to the gross rental amount for any short-term stay -- including cleaning fees -- and every STRO-licensed host is responsible for collecting and remitting it, regardless of whether the property is self-managed or run through a property manager or an online platform. That's a real, meaningful line item to build into any short-term rental income projection for a La Jolla property, on top of whatever platform fees, management fees, and the property-tax and insurance costs documented on the real-cost, property-tax, and coastal-insurance pages.
How La Jolla's Own Demand Profile Affects the Investment Case
Unlike a purely seasonal beach market, La Jolla's demand base is layered: beach-tourism visitors concentrated in the summer peak season documented on the seasonal-recreation page, plus a separate, year-round stream of UC San Diego-related visitors -- prospective students and their families, visiting researchers and conference attendees, and family of graduate students and faculty -- tied to the university's own calendar rather than the beach-tourist calendar. This research did not find or compile specific short-term-rental occupancy or rate data breaking out that university-driven demand from beach-tourism demand, and none is invented here, but it's a real structural difference from a purely seasonal coastal market that's worth factoring into any income projection's seasonality assumptions.
A Realistic Way to Approach This
Before treating short-term rental income as part of a La Jolla purchase's financial case: confirm directly with the City of San Diego Treasurer's office whether a Tier 3 STRO license is currently obtainable for the specific property (not just theoretically available citywide), confirm any Coastal Zone-specific requirement for that parcel, and build the 11.75% TOT plus realistic platform/management fees into the actual income model rather than a gross-rental estimate. Given how close to capacity the Tier 3 license pool appears to be running, a more conservative underwriting approach treats new STRO license availability as uncertain rather than assumed, and weighs the property's fundamentals as a long-term-rental or personal-use asset as the more reliable baseline case. Nothing on this page is financial, tax, or legal advice.

Genuine, disclosed gaps: this page does not state a specific, itemized list of Coastal-Zone-specific short-term-rental restrictions beyond the base citywide STRO ordinance, since none was independently confirmed; it does not state current license-availability figures beyond the two 2026 snapshots cited (which may have changed by the time this page is read); and it does not model specific expected rental income or occupancy for any La Jolla property, since no source-verified figures for that exist in this research. License caps, fees, and availability change; confirm current STRO license status and requirements directly with the City of San Diego Treasurer's office and, for Coastal Zone questions, the California Coastal Commission before making a purchase decision based on short-term rental income.
