Self storage earns its reputation as a resilient asset class from a simple operating fact: month-to-month leases let an operator reprice thousands of small units almost continuously, adjusting to demand far faster than an apartment building or office lease ever could. For a Washington investor weighing where to put exchange proceeds or new capital, that pricing flexibility is the core appeal, along with an operating model that carries lower physical maintenance than most other commercial property types.
Why the Unit Mix Matters More Than Square Footage
A storage facility's revenue is driven by its mix of unit sizes and climate-controlled versus standard space, not simply total rentable square footage. A facility weighted toward small, climate-controlled units in a dense residential submarket, where apartment dwellers need overflow space, generates different revenue per square foot than a facility built around large outdoor RV and boat storage bays on a highway corridor. Evaluating a Washington storage acquisition means looking at the actual unit mix and its historical occupancy and rate trends by size, not just the headline square footage the listing advertises.
Washington's Storage Demand Drivers
Seattle, Bellevue, and the rest of the Puget Sound corridor generate storage demand from apartment renters with limited in-unit space and from small businesses needing overflow inventory storage near dense commercial cores. Spokane and the Tri-Cities see demand tied more to homeownership transitions and seasonal recreational equipment, boats, RVs, and off-road vehicles typical of eastern Washington's outdoor recreation culture. Coastal and mountain-adjacent markets can see meaningful seasonal swings tied to second-home owners and visiting recreational users, which a buyer should factor into occupancy assumptions rather than relying on a flat statewide average.
Operating Costs Run Lower, But Not to Zero
Storage facilities generally require less capital expenditure than apartment or office buildings, no unit interiors to renovate between tenants, no HVAC systems in standard units, but owners still budget for roll-up door repair, security systems, paving, and drainage, along with property management or a franchise-affiliated third-party operator if the owner isn't running it directly.
- Roll-up doors and locking hardware: ongoing repair line item
- Paving and drainage: periodic capital expense
- Security systems and site lighting: recurring and capital cost mix
- Third-party management: typically 5 to 10 percent of gross revenue if outsourced
New Supply Is the Biggest Risk to Underwrite
Self storage looks simple to build relative to other commercial property types, and that ease of entry has led to overbuilding in some fast-growing submarkets, where several new facilities open within a few miles of each other and compete for the same renter pool. A facility that has performed well historically can face real rate pressure once new, better-located competition opens nearby, so evaluating a storage acquisition should include a look at permitted and under-construction supply within a reasonable drive radius, not just the trailing performance of the subject property itself.
Visibility and access from a major road also matter more for storage than buyers sometimes expect, since a meaningful share of new customers still find a facility by driving past it rather than searching online first. A well-run facility on a low-visibility side street can underperform a mediocre facility on a busy arterial, which is a reminder that operational quality alone doesn't fully offset a weak physical site.
Self Storage as 1031 Replacement Property
Investors coming out of a management-intensive asset, particularly small multifamily, sometimes exchange into self storage specifically for the lighter tenant-turnover burden and the ability to reprice rents monthly rather than waiting on a lease renewal cycle. Sourcing a storage candidate for an exchange means verifying trailing occupancy and rate history by unit type before it goes on the written identification, since a facility's headline occupancy can mask a soft rate environment in its largest unit category.
Common Questions
Why do self storage facilities reprice more easily than apartments?
Storage leases are typically month-to-month, letting an operator adjust rates on individual units continuously in response to demand, unlike an apartment lease that's fixed for a term of usually six to twelve months.
Does unit mix affect a storage facility's value more than total square footage?
Yes. Revenue per square foot varies significantly by unit size and whether space is climate-controlled, so two facilities with identical total square footage can have very different income depending on their mix.
What drives self storage demand in eastern Washington compared to Puget Sound?
Puget Sound demand leans on apartment renters and small businesses needing overflow space, while eastern Washington markets like Spokane and the Tri-Cities see more demand tied to homeownership transitions and seasonal recreational equipment.
Are self storage operating costs lower than other commercial property types?
Generally yes, since there are no unit interiors to renovate and no HVAC in standard units, though owners still budget for door repair, paving, security systems, and management costs.
Can self storage be used as 1031 exchange replacement property?
Yes, as real property held for investment or business use. Investors often move into storage from more management-intensive property types specifically for the reduced turnover burden.
