San Diego is experiencing a supply correction after years of steady demand, and as a property owner, you must navigate this meaningful shift to maintain profitability. The city's vacancy rate has risen to 6.1%, a record high that surpasses even the 5.7% vacancy rate during the Great Recession in 2009.
This alarming market shift was brought on by new construction, with around 5,000 units added in 2024 and another 5,600 by 2025. This year, there have reportedly been 4,000 new units, and this trend could continue throughout 2026. The remaining question is: what can you do?
Key Highlights:
- Vacancy hit a record 6.1% in San Diego, surpassing the 5.7% peak seen during the 2009 Great Recession, driven mainly by new construction rather than weaker demand.
- Supply is concentrated, not uniform. Roughly 5,000 units delivered in 2024, 5,600 in 2025, and 4,000 more in 2026, so impact varies sharply by neighborhood and property class.
- Retention beats acquisition. With turnover costs often exceeding the cost of a modest concession, keeping current tenants happy is usually cheaper than re-leasing.
- Price isn't the only lever. Small upgrades (paint, fixtures, internet, smart features) and a smooth move-in process can offset rent-based competition from newer buildings.
- The correction is expected to be temporary. Forecasters anticipate vacancy will plateau and ease as new supply gets absorbed, so decisions should stay grounded in current, not outdated, data.
Understand the Competition
Not all of San Diego is heavily impacted by the influx of rental properties. Instead of considering the entire city, focus on your local area and understand what you’re dealing with. Ask yourself:
- How many similar properties am I competing with?
- What are the amenities they offer?
- What are their rental rates?
- Who is their target market?
By gaining valuable insights on your competitors, you can adjust accordingly, whether it’s your rental rates, the amenities you offer, the kind of tenants you attract, or whether you have to act at all. If you have a Class B rental property in a stable coastal neighborhood, for instance, you won’t have to worry about a Class A luxury apartment complex.
Retain the Tenants You Already Have
If you already have long-term tenants and full occupancy, then the answer is simple. Keep your current residents through efficient property management. In a market where the average cost of a turnover often exceeds the cost of a modest rent concession, you need to get your priorities in place.
Negotiate lease renewals proactively instead of pushing for maximum allowable increases. Some landlords are offering two months free rent, an appealing deal for many tenants, including yours.
A few tactics that can help with tenant retention include reaching out 60 to 90 days before lease expiration, installing new amenities, offering lease renewal incentives, and fixing maintenance issues fast. When tenants feel taken care of, they're more likely to stay.
Don’t Just Compete with Rental Rates
When several competitors start dropping their rent prices, your instinct might be to match them, but rent price isn't everything. Smart tenants weigh all factors to determine which has the best value, so compete with experience and features.
Small, cost-effective upgrades can make a huge difference in the rental market, such as a fresh coat of paint, updated light fixtures, high-speed internet, and smart features, which can put you on par with newer buildings.
A smooth move-in process will also help your chances of finding tenants when your applicants are eager to move in and do not want to go through extensive procedures just to get approved. Respond quickly and professionally to inquiries to set a good tone.
Use Concessions Deliberately
Concessions or incentives tend to become more widespread as the competition intensifies. Used well, they can fill a unit faster than an equivalent face-rent cut while preserving the advertised rent for future comparables and lease renewals.
Everyone loves discounts, but for rental business owners, it’s about what you offer. Match the concession with what’s slowing lease-up. A fee waiver can get price-sensitive renters through the door, while a rent-free period can help you close deals against newer rental properties offering the same rental rate.
Consult Rental Industry Professionals
Even seasoned landlords can’t cover every angle in the rental industry. It’s a complex sector, and there are a lot of factors that can affect your vacancy rate. Each professional you can consult has spent years learning about the ins and outs of their trade, and you could benefit from any advice they may give.
Real estate or leasing agents can offer direct insights on active inventory and pricing adjustments based on market conditions. Property managers can provide hyper-local data on neighborhood rentals, tenant retention, and how you can minimize turnover costs.
Constantly Monitor Market Trends
This won’t be a permanent structural shift. Forecasters are expecting vacancy to plateau and ease back down, so you need to keep an eye out. Making rental business decisions based on outdated market data can lead to huge losses.
Monitoring market trends isn’t just for attracting tenants. Knowing what amenities renters want and what their options are in the rental market will help you shape your property in a way that retains tenants.
FAQs
Why is San Diego's apartment vacancy rate rising if demand hasn't dropped?
The increase is driven primarily by a wave of new construction. Thousands of new units were delivered in 2024 and 2025 alone, outpacing the market's historical absorption rate, not by renters leaving the area.
Does the rising vacancy rate affect every San Diego property the same way?
No. Impact depends heavily on submarket and property class. Newer, luxury-heavy areas are seeing the most softening, while stable coastal neighborhoods and Class B/C workforce housing tend to hold up better.
Should I lower my rent to match nearby competitors?
Not necessarily. Matching rates is one option, but competing on amenities, move-in experience, and responsiveness can be just as effective, and more sustainable for your bottom line.
