Self-storage in Massachusetts.
2026 market data, supply context, dominant cost driver. Sample metro: Boston.
What this state's storage market is doing.
Massachusetts state-level $/sqft not separately published but Boston metro pricing power is the strongest in the US — Yardi flagged Boston as the highest YoY rent growth nationally in March 2026 at +9.7%. State-wide rent levels reflect Boston's premium.
Supply per capita and pipeline.
Massachusetts has the LOWEST self-storage supply per capita among major US states. Boston metro at 0.7 sqft per capita per Yardi is among the most-undersupplied storage markets in the country. Restrictive zoning and high land cost prevent supply response.
What the markets in this state look like.
Boston is the entire story. Worcester and Springfield are materially lower-rent secondary markets.
What's structurally setting the rent.
Acute supply constraint. Boston is the cohort's most-undersupplied market and shows the strongest YoY rent growth nationally. Pricing power is structural, not cyclical.
