The Self-Storage Fortunes: How an Unglamorous Industry Built Serious Wealth

Self-storage is one of the least glamorous businesses in existence and one of the most reliably profitable. The people who built it are not household names, which is itself part of the story — the sector rewards operators who are content to be boring.

Here is where the money came from and where it sits now.

B. Wayne Hughes: the man who invented the category

Public Storage was founded in 1972 by B. Wayne Hughes and Kenneth Volk with a modest initial investment. Hughes had been in property development and noticed that Americans were accumulating more possessions than their homes could hold.

The first facility cost around $50,000 to build. By the time Hughes died in 2021, Public Storage was the largest self-storage operator in the world, and Forbes had estimated his net worth at approximately $4.1 billion.

The business model was almost aggressively simple: buy cheap land on the edge of residential areas, put up low-cost single-storey buildings, charge monthly rent, employ almost nobody. Operating margins in mature self-storage run above 60%, which is extraordinary for a property business.

Hughes converted Public Storage into a REIT in 1980, which changed the tax position and let the company scale. That structural decision did more for the eventual fortune than any operational one.

Bradley Wayne Hughes Jr. and the family position

The Hughes family retained a substantial stake through the REIT conversion. Estimates of the family holding have varied, but at points it represented one of the larger single-family positions in US commercial property.

Hughes Jr. also became known outside the sector as a racehorse owner — Spendthrift Farm, one of the more significant thoroughbred operations in Kentucky, was purchased with self-storage money.

Sovran, Extra Space and the consolidators

The second wave came from operators who bought rather than built.

Extra Space Storage, founded in 1977, went public in 2004 and grew primarily through acquisition. Its 2023 merger with Life Storage created a company with over 3,500 facilities — a scale that would have been unimaginable to the people building single sites in the seventies.

The pattern across all of these is the same: fragmented ownership consolidated by whoever had access to cheap capital. Individual site owners built businesses worth a few million each. The consolidators who bought them built businesses worth billions.

The UK story is smaller and later

Britain came to self-storage roughly fifteen years after the US and at a much smaller scale.

Big Yellow was founded in 1998 by Nicholas Vetch, Philip Burks and James Gibson. It listed on the London Stock Exchange in 2000 and converted to a REIT in 2007. Safestore, its main competitor, has a similar trajectory.

The UK market remains substantially less mature than the American one — self-storage space per head of population in Britain is a fraction of the US figure. The usual explanation is that British homes have lofts and American ones have basements, but the more convincing one is simply that the market started later.

What is notable is where the growth actually is. The large listed operators dominate the headlines, but a significant share of the market sits with independent regional operators, and in dense urban areas the economics favour smaller sites close to customers over large sites on ring roads. Any storage company london based is working with land costs that make the American model impossible, which pushes operators towards multi-storey buildings, combined removals-and-storage services, and collection-based models where the customer never visits the site at all.

That last variation — where the operator collects, stores and returns — is a genuinely different business from renting a room, and it is the part of the sector growing fastest in cities.

Why the returns are so good

Three structural reasons, and they are worth understanding because they explain the wealth better than any individual’s story does.

Customer inertia. The average self-storage tenancy runs far longer than customers expect at signup. Moving your possessions out is work, so people do not.

Pricing power. Annual increases are rarely challenged, for the same reason.

Minimal staffing. A facility with several hundred units can be run by one or two people. Compare that to a hotel with equivalent floor area.

Recession resilience. Downsizing creates storage demand. So does upsizing. The business has demand in both directions of the economic cycle, which is unusual.

The current picture

The sector’s public companies have a combined market capitalisation in the tens of billions. The individual fortunes built from it are mostly held by families rather than founders, since the founding generation is largely gone.

None of them became famous. That is arguably the most instructive fact about the industry: the money was made by people who spent forty years doing something entirely unremarkable, extremely consistently.
