*Stratified random sampling was used where available. Only locations that advertised and sorted pricing online by the respective company and were considered up to Storage Gurus standards were utilized in our analysis. We endeavored to use a representative sample size wherever possible to ensure a fair comparison. We have used the 5X10 self-storage size with a comparable space in full service storage on this homepage. Where prices were unavailable for the selected sizes that location was not averaged into the results. Where multiple prices were available for a single storage size, the higher quality option was sampled. Averages were then taken per provider and in the markets of New York, Washington DC, Chicago, Denver and Seattle. Data was captured throughout the third quarter of 2019.
Given the inherent space utilization difference between professional movers loading storage vaults and public storing in self storage units, cost comparisons conservatively allow for 90% storage vault utilization capacity and 80% self storage unit utilization capacity.
