Three doors into the same business
There are three ways to own a self storage facility. You can build one on vacant land, convert an existing building, or buy one that is already operating. Each produces the same asset at the end, a facility renting units month to month, but the cost, the timeline, the risk and the kind of investor each suits are very different. Most first-time investors are drawn to development because the returns look highest on paper. Most first-time investors would be better served by acquisition. This article explains why, and when the other two make sense.
Acquisition: buying an operating facility
Buying an existing facility means buying an income stream that already exists. The rent roll is real, the trade area has already proven it supports the facility, and financing is available on the day you close because the lender can underwrite actual NOI rather than a projection.
The cost is that you pay for the income up front. In the current Canadian market, stabilized facilities trade at cap rates from the low five per cent range for premium urban assets to above 6.5 per cent for tertiary product, which means a facility earning $600,000 of NOI costs somewhere between $9 million and $12 million. That price already reflects most of the value the previous owner created.
The return for an acquirer comes from three sources. The first is operating improvement: buying a facility that has never been revenue-managed, has an outdated website, no online rentals and a rate sheet that has not moved in three years, and running it professionally. The gap between a well-run and a poorly-run facility can be 15 to 25 per cent of NOI, and that gap is what institutional buyers are paying for across Canada right now. The second is expansion: many older facilities sit on land with room for another building or a row of drive-up units, which can be added at a fraction of the cost of a new site. The third is simply holding a durable income stream through a cycle.
Timeline: 90 to 180 days from offer to closing. Risk: low to moderate, concentrated in due diligence, which is why the rent roll article matters. Suits: first-time investors, anyone financing with conventional debt, and anyone who wants cash flow from day one.
Development: building from the ground up
Ground-up development means buying land, taking it through municipal approvals, building the facility and then leasing it up from zero. It produces the newest, most efficient building with the unit mix the market actually wants, and when it works, the return on cost is well above what an acquisition can produce.
The costs are higher and less certain than newcomers expect. In Alberta, 2026 base construction costs run roughly $90 to $140 per square foot for single-storey drive-up buildings and $200 to $300 per square foot for multi-storey climate controlled buildings, before land, site work, soft costs and financing. In Metro Vancouver and the Greater Toronto Area, land alone can exceed the entire construction budget of a prairie facility. All-in development cost for a multi-storey urban facility in a major Canadian market commonly lands between $250 and $400 per rentable square foot once land, site servicing, permits, design, interest during construction and lease-up carry are included. Tariffs on steel, aluminum and building components have added to that since 2025.
The timeline is the other cost. Municipal approval for storage is slow in most Canadian cities, because planners often prefer housing or employment uses on the same land and because storage generates few jobs. Rezoning and development permits commonly take 12 to 24 months, construction another 12 to 18, and lease-up 24 to 36 months after opening. A developer breaking ground today is looking at four to six years before the facility is stabilized and can be refinanced or sold on its income. Why Municipalities Should Welcome Self-Storage Development covers the planning argument in detail.
Risk sits in three places: entitlement risk (the approval does not come, or comes with conditions that break the budget), construction risk (cost overruns and delays), and lease-up risk (the facility fills slower than the pro forma assumed, covered in the next article). Financing reflects that risk. Construction lenders want more equity, typically 35 to 45 per cent, charge more, and advance in draws against completed work.
Development suits experienced investors with patient capital, a development partner who has built storage before, and a market they have verified is under-supplied at the trade-area level. It does not suit a first-time investor’s first project.
Conversion: turning an existing building into storage
Conversion sits between the two. An existing building, most often a vacant big-box retail store, a warehouse, an industrial building, a grocery store or an office building, is fitted out with storage units, an office, access control and climate systems. The building envelope, the parking and often the zoning already exist, which cuts both cost and time compared with ground-up construction.
Good conversion candidates share a few traits: a clear span structure with adequate floor loading and ceiling height, a location with visibility and access, a lot with room for loading and some drive-up units, and a purchase price that reflects the building’s obsolescence for its original use rather than its potential as storage. Vacant retail boxes in secondary markets, where the landlord has struggled to re-tenant for years, are the classic case.
Costs vary widely. Interior fit-out of a suitable building typically runs $50 to $90 per square foot for units, corridors and access control, with climate control, sprinklers, electrical upgrades and elevator work on top where needed. Add the purchase price of the building and the total often lands well below new construction. The catch is that a building not designed for storage carries surprises: structural limits that prevent mezzanines, code upgrades triggered by the change of use, sprinkler and fire separation requirements, and the simple fact that a retail box is deeper than a storage building wants to be, which produces long corridors and lower efficiency.
Timeline: nine to 18 months from purchase to opening if the zoning permits storage, longer if a change of use requires municipal approval. Risk: moderate, mostly in the building condition and the change-of-use process. Suits: investors who can find the right building, which is often the hard part, and who have a contractor with storage conversion experience.
Comparing the three
The acquisition buyer pays the highest price per square foot and takes the least risk. The developer pays the lowest cost basis per square foot in the long run and takes the most risk over the longest time. The converter sits in between on both.
A rough comparison for a 50,000 rentable square foot facility in a secondary Canadian market: acquiring a stabilized facility might cost $11 million to $13 million with income from day one; converting a suitable vacant building might cost $7 million to $9 million all-in with 18 months to open and two years to stabilize; developing from the ground up might cost $10 million to $14 million all-in, more in a major metro, with four or more years to stabilization. The developer’s reward for the extra time and risk is a stabilized asset that may be worth 20 to 40 per cent more than it cost to build. The acquirer’s reward is that the money starts working immediately and the outcome is far more certain.
Why most first-time investors should buy first
Every skill a storage owner needs, from reading a rent roll to setting rates to managing a remote facility, is learned faster on an operating facility than on a construction site. An acquisition also produces the operating history, the lender relationship and the management platform that make a later development or conversion easier to finance and run. The investors who develop successfully in this sector almost all owned facilities first.
The exception is an investor who already has development experience in another asset class and a partner who knows storage. For that investor, a well-located conversion in an under-supplied secondary market is often the best risk-adjusted entry.
The next article covers lease-up: how long a new or converted facility takes to fill, what it costs to carry it, and how to set a break-even occupancy target.
