Short-Term Rental Investing in San Diego, CA: Coastal STR Market Guide
Avg ADR: $300–$1,200+/night (coastal properties, peak summer) | Annual occupancy: 65–78% coastal | California income tax up to 13.3% | California does NOT conform to federal bonus dep | Tier 2 non-primary STR permits capped (~6,800 city-wide) | Transient Occupancy Tax: 10.5% | Year-round climate drives consistent demand | Properties $800K–$5M+ in coastal zones
San Diego occupies a unique position in the U.S. STR market: it is simultaneously a major metropolitan area (3.3 million in the metro) and a world-class coastal resort destination. With 70 miles of Pacific coastline, an average annual temperature of 70°F, and a tourism infrastructure that draws 35+ million visitors annually to the region, San Diego's STR market benefits from demand drivers unavailable in most comparable coastal markets. Unlike seasonal beach markets that peak in July–August and slow dramatically in winter, San Diego's climate produces genuinely year-round bookings — occupancy rates in January and February rival summer months in many other coastal markets.
San Diego Market Overview: Climate-Driven Year-Round Demand
The San Diego coastal STR market spans several distinct submarkets, each with its own character and price point. Mission Beach and Pacific Beach are the highest-volume STR neighborhoods — dense with rentals, strong occupancy, moderate ADRs ($300–$700/night). La Jolla commands the highest ADRs in the city ($500–$1,500+/night) driven by the cliffs, coves, proximity to UC San Diego, and a luxury visitor demographic. Ocean Beach has a bohemian character with strong demand and moderate prices. Coronado Island (technically a separate city) has different regulations and extraordinary ADR potential given its iconic beach and Hotel Del Coronado proximity. North County coastal (Encinitas, Carlsbad, Del Mar) offers strong demand with lower regulatory complexity and competitive pricing.

California's Bonus Depreciation Non-Conformity: What It Means for San Diego Investors
California's non-conformity with federal bonus depreciation applies to all San Diego STR investors. The mechanics are identical to the rest of California: federal bonus depreciation deduction is immediate in Year 1; California requires adding back the excess and amortizing over MACRS lives. For a $1.2M Pacific Beach property with $264,000 in bonus-eligible assets, Year 1 federal savings at 37% = $97,680. The California addback at 13.3% increases state taxes by approximately $35,112 in Year 1, but creates CA deductions totaling $35,112 spread over years 2–15 (depending on asset class).
San Diego's combination of high property values, strong year-round occupancy, and the STR loophole's ability to transform rental losses into offsets against ordinary income makes cost segregation particularly powerful in this market. Even with California's timing difference, the immediate federal cash benefit justifies cost seg on most San Diego coastal properties over $800,000.
Cost Segregation Profile: San Diego Coastal Properties
San Diego beach properties have strong personal property and land improvement profiles. Key reclassifiable components: outdoor pool and spa systems (15-year), rooftop deck and outdoor living areas (15-year), beach-facing patios and hardscape (15-year), outdoor furniture and entertaining equipment (5-year personal property), luxury interior furnishings and entertainment systems (5-year), outdoor shower systems (15-year personal property), coastal landscaping and lighting (15-year), and bonus: solar systems and battery storage are common in San Diego and may qualify for 5-year MACRS depreciation plus ITC.
San Diego STR Regulations
The City of San Diego's STR regulations — adopted after years of political debate — created a tiered permit system. Tier 1 (primary residence, part-time) and Tier 3 (home-share, owner on-site) permits are less restricted. Tier 2 (non-primary-residence investment STRs) permits are capped at approximately 1% of the city's total housing stock (approximately 6,800 permits) and allocated through an annual lottery. This cap means Tier 2 permits have significant embedded value and are limited in supply. Properties sold with active Tier 2 permits command premiums. The California Coastal Commission has jurisdiction over coastal zone development. Unincorporated county areas and neighboring coastal cities (Encinitas, Carlsbad, Del Mar, Coronado) each have their own ordinances, generally with more permissive investment STR rules.
