Self-Storage Facility Construction in Wyoming

Self-storage construction in Wyoming growth towns: drive-up rows, climate-controlled buildings, drainage, phasing, snow and wind loads, and gate systems.

Bar Nunn grew about 35 percent in a decade, from 2,213 residents in 2010 to 2,981 in the 2020 census. Mills went from 3,461 to 4,034. Evansville added about 200 people, from 2,544 to 2,746. All three sit on the edge of Casper's metropolitan area, and all three are the sort of place where a household runs out of garage before it runs out of stuff. Self-storage follows that growth line, and that is where we start.

A storage facility is a repetitive building on a flat lot, which makes it a close cousin of a small warehouse shell. Drive-up units are tilt-wall or pre-engineered metal with roll-up doors. Climate-controlled units are a heated shell with corridors. What separates a good facility from a poor one is the site: how trucks turn, how water drains, where the gate sits and how the first buyer sees it from the highway.

We build the shell, the slab and the site. Owners comparing a pre-engineered metal building to masonry or panels for the drive-up rows will find the answer depends on wind, snow load and how the facility will be phased.

The lot decides the return

Storage owners earn from rentable area per acre, so every aisle width and drainage swale counts. A drive-up row needs a travel lane wide enough for a moving truck to turn and park beside the door; thirty feet is a common starting point, and it varies with the unit depth and the vehicles you expect. Corner units, RV spaces and trailer parking sit at the back of the lot where land is cheapest.

Drainage and grading matter more than people expect. A facility is mostly roof and paving, so runoff is high, and a detention basin may take a meaningful share of the lot. We work out the grading and detention with the civil engineer before the building layout is fixed. A flat lot sheds snowmelt faster than a poorly graded one, and nobody wants a puddle at a roll-up door that freezes overnight.

Rows, corridors and the office

Drive-up rows are the simplest build: slab, steel or panel walls, a shallow roof, and roll-up doors at the spacing the unit mix calls for. We pour a thickened edge at the door line and set door tracks to a template, because roll-up doors that bind in January are the main service call after opening.

Interior-corridor buildings add insulation, a heating plant, interior partitions and a lobby. The management office sits near the gate and often includes a small retail counter for locks and boxes. We build it as a small commercial office, with a restroom, a security panel and a data connection for the gate system. An office like that has the same wind and snow concerns as any office building, only smaller.

How the trade work is coordinated

Concrete is the foundation of the job and the part we control tightly. Slab pours, edge forms, sawcutting and curing are done by the trade crews on a schedule that suits the weather. A storage slab does not need a warehouse flatness spec, but it does need positive drainage and no cracks wide enough to catch a hand truck.

Erection is next. We set wall panels or steel frames and finish roof and trim. For small facilities, the concrete, erection and enclosure trade packages follow a repeating row-by-row sequence. That rhythm lets an owner phase the project: build half now, open, and add rows as the first ones fill. The spec warehouse shell method of building ahead of tenants is the same logic, and our notes for developers and REITs on phasing apply directly.

Where demand is building

Growth in the small towns around Casper pushes demand beyond the city. Bar Nunn's street pattern follows the runways of the old Wardwell Field, which means lots are large and often long, a good shape for storage rows. Mills has franchise agreements with several telecom providers to build fiber optic networks, so a smart gate and cameras can run on fast service without a long extension.

Energy and mining towns have a different pattern. Workers in temporary housing need a place for gear and vehicles, and storage demand follows the work cycle. A facility along I-80 or I-25 may see turnover that tracks oil, trona or wind construction schedules. We help owners size the first phase to what the local market can absorb, with space reserved to expand.

What moves the price

Door count and unit mix drive the building cost: more small units mean more partitions and more doors. Climate control adds mechanical equipment and insulation; for a single-level drive-up facility, an unheated shell saves a great deal. Concrete, paving and detention follow site size. Utilities are modest, but a long water or power extension can erase a land discount.

Wind and snow loads affect the roof. Wright's published standards call for a 30 psf ground snow load and 90 mph wind, and Evanston's call for 40 psf minimum and 100 to 110 mph depending on exposure. A building that works on the Casper side of the state may need heavier framing farther west. We design to the numbers the local building department publishes. Our site utilities package work covers the underground side of the budget.

Services around a storage job

A storage lot is a small truck court. We lean on the same concrete and paving methods used for a truck court and trailer yard, since moving trucks and trailers tear up thin asphalt quickly. Where the owner adds an RV or trailer yard, a concrete apron at the gate saves repair costs.

Owners with an existing industrial building sometimes ask about converting part of it. That is a warehouse expansion question in reverse: carving self-contained units out of a larger floor. Fire separation, door openings and access routes need review before we price it, but the economics can work for a building that has lost its original tenant.
