Parking rents climbed 4.4% year-over-year in September, the strongest increase since Yardi Matrix began tracking RV and boat storage rates, driven by sharp gains for smaller parking units and double-digit growth in dense metros like Los Angeles and New York. Rent growth was weakest in Sun Belt markets with heavy recent development, as new supply continues to weigh on performance. Development and sales activity have both slowed notably from their 2022–2024 peaks, bringing supply growth back toward more sustainable levels.
