San Diego STR Rules at a Glance

Tier 1 (≤20 days/year, $100/year): broadly allowed | Tier 2 (home-share, owner-occupied): $1,000/yr, no cap | Tier 3 (whole-home, non-owner-occupied): capped at 1% of housing units citywide | Tier 4 (Mission Beach exception): unlimited whole-unit | SD TOT 10.5% | 2023 ordinance fully phased in 2024

San Diego's 2023 STR ordinance (effective 2024) introduced one of the most structured tier systems in the country. Tier 1 (occasional hosts, ≤20 nights/year) faces minimal requirements. Tier 2 (owner-occupied home-share) has no cap. Tier 3 (whole-home non-owner-occupied) is capped citywide at 1% of dwelling units, with permits issued via lottery. Tier 4 carves out Mission Beach as a special unlimited-permit zone given its long-standing tourism economy. The ordinance was politically calibrated to allow significant STR economic activity while protecting long-term housing supply.

Licensing & Registration

Tier 1: $100/year, $25 application, no inspection required, capped at 20 nights of unhosted stays. Tier 2: $1,000/year + life-safety inspection, owner-occupancy proof, no nights-cap. Tier 3: $1,000/year + lottery-allocated permit (the binding constraint citywide outside Mission Beach), full inspection + insurance + 24/7 contact. Tier 4 (Mission Beach): $1,000/year + inspection + insurance, no cap on permits issued (geographic exception to the 1% citywide ceiling).

Lodging & Occupancy Taxes

San Diego Transient Occupancy Tax 10.5% on stays under 31 days. CA state sales tax generally doesn't apply to lodging. Effective SD STR lodging tax: 10.5%. Stays of 31+ days are exempt. Airbnb collects SD TOT automatically. California's state-level bonus-depreciation non-conformity applies as elsewhere in the state.

Penalties & Enforcement

Operating without a tier-appropriate license: $1,000-$5,000 per violation. The city actively cross-references listings against the licensing database. Permits revoked for repeat violations face a 24-month bar on reapplication for the same property. Tier 3 lottery winners who don't activate within 180 days lose the permit, which returns to the lottery pool.

Recent Changes

2024-2025 Tier 3 lottery cycles have been extremely competitive — typically 10:1 application-to-permit ratios in popular neighborhoods (Pacific Beach, La Jolla, North Park). Mission Beach (Tier 4) has remained the practical unlimited-permit zone but property prices reflect that — entry-level Mission Beach STR-eligible properties trade at meaningful premiums.

Tax Strategy for Compliant Investors

Even within San Diego's regulatory framework, properly-licensed STR investors retain the federal tax stack. Cost segregation accelerates depreciation, the STR loophole can convert losses to active-income offsets for materially-participating owners, and 100% bonus depreciation under OBBBA applies to all reclassified 5- and 15-year assets. California decouples from federal bonus depreciation, so state-level adjustments apply — but the federal benefit remains substantial. See bonus depreciation explained.

Frequently asked questions

What's the practical SD STR investor pathway?
Three pathways. First: Mission Beach (Tier 4) — the only no-cap zone, prices reflect that. Second: Tier 2 owner-occupancy (house-hack) — buy a multi-unit property, occupy primary, rent secondary unit. Third: Tier 3 lottery — apply for permits in target neighborhoods, expect to wait 1-3 years for an allocation. New investors typically pursue Tier 4 (capital-intensive) or Tier 2 (hands-on).
Can I transfer a Tier 3 permit when I sell the property?
Tier 3 permits are tied to the property, not the owner. New owners can apply to transfer the permit within 60 days of closing. The transferability creates a 'permit value' that gets priced into Tier 3-permitted properties. Properties without Tier 3 permits in capped neighborhoods cannot easily acquire them through resale.
Is the Mission Beach premium justified by the unlimited-permit status?
Generally yes for serious operators. Mission Beach properties command 15-30% price premiums versus comparable non-Tier-4 properties, but the regulatory clarity (and the strong Mission Beach market fundamentals) supports the premium for investors planning long-term operations. Short-term flippers don't benefit from the regulatory premium the way long-term operators do.
