Is the national housing and moving market currently showing signs of improvement?

The national average advertised street rate for self-storage units dipped to $16.39 per square foot in August 2026. This 0.5 percent month-over-month decline reflects a cooling market for consumers looking to store personal belongings.

Why it matters

Rising sector oversupply, combined with weak migration and sluggish home sales, continues to pressure rental fundamentals. For households, these conditions suggest potential savings as operators compete for tenants in a market with nearly 44 million square feet in development.

Average advertised street rates for 10x10 units dropped to $16.39 per square foot in August 2026, a 0.5 percent contraction from the previous month. This move comes as the U.S. development pipeline accounts for 2.1 percent of total existing inventory.

The details

The sector's development pipeline currently spans 2,392 properties, including 594 active construction projects, 1,499 planned sites, and 299 prospective developments. This expansion, totaling 43.8 million rentable square feet, increases competition for tenants across many regions. While most markets have seen rent pressure, rare pockets like Austin and San Francisco maintained positive growth for climate-controlled units.

August 2025 marked the basis point reference period for the construction pipeline.
July 2026 served as the baseline for monthly rate and supply comparisons.
August 2026 provided the latest national self-storage reporting period.

Money Landscape

The current supply-side expansion continues to defy historical patterns of rapid cost increases for consumers. This period marks a structural departure from the post-pandemic supply crunch, favoring tenants as developers complete thousands of new projects.

If you are currently paying for a storage unit, the recent national cooling suggests it may be a good time to compare your current rate against local competitors. Consult a financial professional to discuss how reducing recurring monthly expenses fits into your broader household budget goals.

The takeaway

While self-storage rates are currently softening, long-term costs remain dependent on your specific metropolitan market and unit type. Review your current rental agreement to ensure your rate remains competitive with current local market listings.
