Self-Storage Facility Construction in Texas
A storage facility earns its money from the mix of unit sizes and the rate per square foot, and the building has to be designed backwards from that mix. Ten-by-ten units rent fastest, ten-by-twenties carry the vehicles and small-business stock, and a climate-controlled hallway commands a premium. The frame, the door spacing and the corridor widths all follow from that mix, which is why we sit down with an owner or an operator and a unit mix table before we sketch a roof.
Pre-engineered metal is the standard structure for the business, for a plain reason: the repeating bay that makes a good storage building is exactly what a rigid frame or a single-slope roof system delivers. We build drive-up row buildings, multi-story climate-controlled buildings with elevators, covered RV and boat storage, and the small manager's office that sits at the gate. Buyers range from first-time independent owners to operators building several sites.
Here is what the work looks like in Texas, including the part that surprises first-time developers: the site costs more time than the building.
Unit mix, door modules and hallway width
Drive-up buildings are a repeating pattern of doors, usually on 10 foot, 12 foot or 15 foot modules, with interior walls of light-gauge steel studs or sheet metal partitions that can be shifted if the demand mix changes. A 30 foot deep single-slope building with a door every 10 feet gives you a flexible product, and the roof can shed water to the rear where a gutter runs to the detention basin.
Interior climate-controlled buildings are different. They need a hallway wide enough for a hand truck and a cart, usually 5 to 6 feet, with fire separation and sprinkler heads in the right places. Multi-story versions need an elevator, a freight-sized door at the dock and a structure that carries floor loads of at least what the code requires for storage. We use the self-storage metal building service for the details of frame and door packages.
Storage demand follows people who move
Storage does best where people move in and out often, and Texas has plenty of those markets. In Killeen, the III Corps and Fort Hood is the top employer at 32,000 employees in the city's 2024 report, and military households relocate on a regular cycle. In El Paso, Fort Bliss is home to 41,527 direct employees, including 30,288 active-duty personnel. In San Angelo, Goodfellow Air Force Base has 6,567 direct employees, with 5,516 active duty.
We read those numbers as a demand signal, not a guarantee, and we tell owners so. A base town is a proven market for small units, vehicle storage and RV space, but each trade area still needs a feasibility study from an operator or an appraiser. Our job is to build the product the study calls for, to the schedule the lender needs.
From pad to gate: what we build
On a typical new site we handle the pad, the footings, the slab, the frame, the roof and wall panels, the doors, the interior partitions, the hallway lighting and the sprinkler rough-in where it applies. Outside, we build the paving, fire lane, gate and keypad pedestal, and the sign base. If the owner has a general contractor, we work as the building subcontractor and hand over a weathertight shell on a date.
The slab is more important than it looks. Customers drive a moving truck onto it, a forklift unloads on it, and the doors must align with it. An uneven slab makes roll-up doors bind, which becomes a maintenance issue for the life of the facility. We pour to a flatness tolerance and set door jambs by laser. For related buildings, see our pages on warehouses and self-storage operators. A manager's office with a leasing counter echoes the layout on our retail shopping center page.
Zoning, drainage and the plan review
Storage development is often decided before the building permit, at the zoning and site plan stage. Many cities require masonry or decorative panels on the street frontage, landscape buffers, limits on outdoor storage and a specific lighting level at the property line. Drainage is the bigger item: a mostly-paved site sends a lot of water downstream, so a detention basin or underground system is common, and the civil engineer sizes it to local rules. A UT Austin and TxDOT research report on expansive clays describes methods for estimating how far a central Texas soil can swell, and that movement can crack a slab, so a geotechnical report is not optional.
On the building side, the state sets the International Building Code as the municipal baseline, and cities add amendments by ordinance. Accessibility registration with TDLR applies to projects of $50,000 or more. We handle the submittal, track the comments and talk to the fire marshal about gates, Knox boxes and sprinkler needs.
What moves the price per rentable foot
Three things drive cost: the door count, the climate control, and the site. Doors are the largest single component. A roll-up door costs the same whether it sits on a 5 by 10 or a 10 by 30 unit, so the smaller the unit, the higher the door cost per square foot. Climate-controlled space adds insulation, HVAC, finished corridors and electrical, and it is priced as a different product from drive-up.
Site work follows: paving, detention, utility taps and gate equipment. Hail matters too. With 878 hail events recorded in Texas in 2024, a roof that dents or leaks becomes a rent-roll problem, and we offer standing seam panels or heavier-gauge sheeting at an added cost that insurers often reward. Owners who plan to build in phases save mobilization by sizing the utility and the pad for the final footprint at the start, and we help with that planning on expansion work.

Common Questions
How many units can a one-acre site hold?
It depends on the setbacks, detention and fire lanes. A tight infill site with a single story of mixed units has less net rentable area than people assume, often a good deal less than the lot size suggests. We prepare a layout once we see the survey and zoning and report the net rentable footage honestly.
Is a pre-engineered metal building cheaper than tilt-up for storage?
Almost always for single-story drive-up and for most climate-controlled buildings. The repeated bay suits a rigid frame, steel arrives in weeks, and the walls are a quick panel system. Tilt-up costs more per square foot and takes longer in this use.
What do roll-up doors cost compared to the building?
A large share. Doors, hardware and installation are one of the biggest lines in the budget, which is why unit mix matters so much. A mix heavy on small units has more doors per square foot.
Do I need sprinklers?
It depends on the building size, the height and the city. Multi-story and large interior-hallway buildings often need them, while small drive-up rows may not. We ask the fire marshal during design, not after.
How long to build a drive-up facility?
Site work and permits take longest. Once the pad is ready, a drive-up row building is erected in weeks. We give a written schedule that shows permit review, steel delivery and the door install.
