Key takeaways
- The gate operator, keypads and access control panel get their own circuits, underground conduit where the run crosses the drive, and surge protection.
- LED fixtures on photocells or timers keep drive aisles and corridors lit without staff on site.
- Adding a climate controlled building to an older site starts with a load calculation, because that is often where the service runs short.
- Gate work is scheduled so tenants keep their access, and any shutdown of the gate circuit is planned with you in advance and kept short.
Self storage electrical work comes down to a few systems that cannot go down: the gate, the keypads, the cameras, the lights in the drive aisles and corridors, and the cooling in climate controlled buildings. Most storage sites run with little or no staff on the property, so a failure is usually found by a tenant standing at a gate that will not open. This guide covers how we wire, repair and maintain those systems at San Antonio storage facilities, and how the work is scheduled so tenants keep their access while it is done.
What electrical systems does a self storage facility depend on?
A self storage facility depends on the gate, the keypads, the cameras, the lights in the drive aisles and corridors, and the cooling in climate controlled buildings. Gate and access equipment gets dedicated circuits, underground conduit and surge protection, and LED lighting on photocells or timers keeps the site lit without staff on site.
Each of those systems has a different job. The gate and keypads decide who gets in. The cameras and the recorder keep a record of who did. The lighting lets tenants find their unit and carry their things after dark. The HVAC in a climate controlled building protects what is stored inside it. The rental office ties them together with its own lighting, receptacles, point of sale and network.
Because so much of the site runs on its own, the panel is the first place we look on any visit. Every circuit that feeds the gate, the cameras or a row of lights should be labeled so that whoever opens the panel, at any hour, can tell what feeds what.
How should gate and keypad power be wired?
The gate operator, the keypads and the access control panel each need their own circuits, not a share of a lighting circuit. The runs out to the gate often cross the drive, so they go underground in conduit. A dead gate locks every tenant out, so these circuits get surge protection and a clear label at the panel.
A gate operator that shares a circuit with other loads can stop when something else on that circuit trips. Keeping the gate, the keypads and the access panel on dedicated circuits means a fault somewhere else on the site does not reach the entrance.
The underground run is the part that is hardest to change later. Conduit placed under the drive, sized with room for the cable the access vendor will pull, saves cutting the pavement a second time when a keypad is added or the system is replaced.
Surge protection matters here more than almost anywhere else on the site. Gate operators and keypads sit outdoors at the end of long runs, and a gate that stops after a storm is one of the most common calls a storage facility makes.
Protection for the access equipment and the panel that feeds it is part of our surge protection work.
What lighting works best for storage drive aisles and corridors?
Drive aisles, building ends and interior corridors are where tenants walk with their hands full, often after dark. LED wall packs, pole lights and corridor fixtures on photocells, timers or occupancy controls keep them lit without staff on site, and a retrofit cuts the number of lamps that burn out between visits.
Outdoor lighting usually runs on photocells or timers set to the gate hours, so the site is lit while tenants can get in. Interior corridors in climate controlled buildings suit occupancy controls, which bring the lights up when someone walks in and turn them down when the hall is empty.
A row of lights that goes dark at once usually points to the control, not the fixtures. A failed photocell or timer can take out a whole aisle, and it is one of the faults a scheduled site check is meant to find before a tenant does.
Older sites with a mix of fixtures are good candidates for an LED lighting retrofit. Parking structures face the same long hours and empty areas, as our guide to parking garage electrical work explains.
How are security cameras and the network closet powered?
Cameras and the recorder are only as good as the power behind them. We run the circuits for the camera power supplies and the network closet, and coordinate the cable routes with your security vendor so nothing is pulled twice. The vendor sets up the cameras, the recorder and the software.
The network closet holds the recorder, the switches and often the access control panel. It needs a dedicated circuit, and the equipment in it benefits from the same surge protection as the gate. A closet that loses power stops recording at the moment the record may matter most.
Before any conduit goes in, we agree with the security vendor where each camera mounts, where its power supply sits and which pathway its cable takes. That one conversation keeps two crews from running separate lines down the same building.
Can an older storage site carry a new climate controlled building?
Sometimes, and a load calculation is how you find out. Climate controlled units add HVAC equipment that has to be on circuits sized for it, with disconnects where the code requires them. Adding a climate controlled building to an older site is often where the existing service runs short, which the calculation shows before anything is ordered.
Many older storage sites were built with drive up units, a gate and some lights. A climate controlled building asks far more of the service than any of those. The load calculation starts from the HVAC equipment sheets and adds the new building's lighting and receptacles to what the site already uses.
If the service has to grow, the upgrade is coordinated with CPS Energy, because the utility decides what it can provide at the property. Starting that conversation early keeps a finished building from sitting empty while the service catches up.
What does the rental office build-out involve?
The rental office is a small commercial build-out: lighting, receptacles, the point of sale and the network. It is wired to the layout like any small office, with its own circuits kept separate from the gate and site lighting, so work in the office never takes down the entrance or the drive aisles.
The point of sale and the network equipment in the office need circuits of their own. Many offices also hold the monitors for the cameras, and some hold the access control panel, so the office and the network closet are often planned together.
An office remodel or a new office follows the same steps as our tenant build-outs, from the plans through the final inspection.
What goes wrong at storage facilities, and how is it prevented?
The usual failures are a gate that stops after a storm, a row of lights on a failed photocell, and a tripped circuit nobody notices until a tenant calls. Surge protection, labeled panels and a maintenance agreement that checks the site on a schedule catch most of them before the phone rings.
A storage site with no staff on hand needs someone looking at it on purpose. A scheduled visit tests the photocells and timers, checks the gate and access circuits, looks over the surge protection and confirms the panel labels still match the site.
- Put the gate, keypads and access panel on dedicated, labeled circuits.
- Protect the access equipment and the network closet from surges.
- Run the gate conduit underground with room for future cable.
- Set the site lighting controls to the gate hours.
- Run a load calculation before adding a climate controlled building.
Scheduled site checks are set in a maintenance agreement. When the gate goes down after hours, our emergency commercial electrician line makes the circuit safe and you get a written price for the repair.
Does self storage electrical work need a permit in San Antonio?
Inside the city limits, electrical permits come from the City of San Antonio Development Services Department under the 2023 National Electrical Code the city adopted effective May 1, 2025. We pull the permit where the work needs one and meet the inspector, and gate work is scheduled so tenants keep their access throughout.
Each job gets a written bid for its scope before work begins, and any change gets a written price and your approval before it is done. Any shutdown of the gate circuit is planned with you in advance and kept short, so tenants are not left at a locked gate.
For everything we do at storage sites, see our self storage electrician page, and for the rest of our scope, commercial electrical services. Rural sites with long runs between buildings face some of the same questions covered in our guide to agricultural electrical work. To plan gate, lighting or building work, describe the site through our contact page, and the owner will respond the same business day.
