Which factors underpin the local boom of self storage development in the past few years?

The self-storage sector has seen a boom in new construction since the economic recovery coming out of the Great Recession. Driving this trend is a flood of new sources of institutional capital combined with the continued improvement in operating metrics for existing storage facilities.

Rents, occupancy rates and operating incomes have all risen faster than in almost any other commercial real estate asset class, pushing opportunistic developers to enter the market. Across most markets we have seen an increase in supply in excess of 10% over the past 6-7 years.

Where does local demand for self storage come from?

Self-storage demand has benefited from a confluence of events, many of which were accelerated during COVID; several of the most prominent reasons for the increased demand include the work-from-home requirement with many folks reorganizing space to accommodate efficient workspace, home gym equipment due to fitness center closures, small business closures that pushed these owners to find storage for their most valuable assets, heightened divorce rates, and college-aged kids moving back into their parents' homes. These are some primary drivers of the increased demand for storage.

What major economic events affected the self storage industry in San Diego?

COVID has likely been one of the main factors; however, the cost of living in San Diego has pushed folks into smaller spaces with limited storage options. Combined with the amount of folks moving into the San Diego area to enjoy the climate and all that San Diego has to offer is certainly a factor impacting storage demand.

How do you envision the future of the local self storage industry, in the medium - and long-term?

As the economics of building storage have gotten tougher with rising land prices, limited supply of viable sites and the increased costs to build, there will likely be a slight deceleration in the amount of new building in San Diego in the mid-term. Longer-term will be determined by the continued improvement in self-storage profitability.

If the metrics continue to improve, the demand for new self-storage projects will certainly remain elevated and developers will get more creative. Most new self-storage projects built today are multi-story, climate-controlled and architecturally pleasing buildings, not the stereotypical drive-up facilities of the past!
