magine you have a piece of land that is perfect for self-storage development. The visibility is unmatched off a major highway, the population density is high, the zoning is in place, and there aren’t any competitors looking to build self-storage near your site anytime soon. You’ve done your due diligence and are ready to build.

Now, how do you create the most efficient unit mix that maximizes profit and provides what customers are seeking? Do you build non-climate-controlled units that all have drive-up access? Or do you build a multistory building with all climate-controlled units? Developers face these types of questions every day. This month we will unpack the value proposition of climate-controlled self-storage units as well as provide data on climate-controlled premiums across all the major MSAs.

Climate-controlled self-storage units provide a unique service to customers with special needs. Customers who store valuable items such as antiques, appliances, artwork, documents, instruments, or furniture benefit from climate-controlled storage options, as these special items could be damaged in extreme temperatures or humidity.

Naturally, a customer is charged more for the use of a climate-controlled unit. According to the SSA’s 2023 Self Storage Demand Study, more than 30 percent of renters are willing to pay more for a climate-controlled unit. So, developers should only build climate-controlled units since they make the most money, right? It depends. Constructing climate-controlled facilities is more costly than constructing traditional facilities. In addition, it’s important to understand your trade area and if customers are looking for a climate-controlled storage product. If climate-controlled storage is undesirable in your area, then you won’t be able to charge enough to justify the extra cost to build climate-controlled storage.

The top five MSAs where climate-controlled rates are achieving the highest premium over non-climate-controlled rates are listed in the Top 5 MSAs table. We’ve also included the bottom five MSAs, where climate-controlled rates aren’t achieving much, if any, of a premium over non-climate-controlled rates, in the Bottom 5 MSAs table. We’ve used a unit size of 10-by-10 and average street rates from February 2024 to January 2025.

It’s no surprise that high humidity areas like Louisiana and Alabama top the list of markets with the highest climate-controlled premium. On the flip side, areas with mild climates in California and the northwest aren’t commanding a premium for climate-controlled units. Interestingly, in San Francisco, non-climate-controlled units have higher advertised rates, suggesting that customers don’t see a significant value-add from using climate-controlled storage. Although difficult to confirm, this could also indicate an oversupply of climate-controlled units. The next time you are thinking of building climate-controlled units, look at the data to see if the juice is worth the squeeze.
