Self-Storage Utility Costs: What Every Multi-Facility Operator Should Be Paying in 2026
Most self-storage operators can tell you exactly what they pay for insurance, staffing, and marketing down to the dollar. Ask the same operator what they pay for electricity, water, and gas across their portfolio, and the answer gets vague fast. Self-storage utility costs are one of the least reviewed line items in the entire industry, and that gap is where a meaningful amount of recoverable margin sits.
This guide breaks down what self-storage utility costs should actually look like in 2026, the categories most operators miss entirely, and how a formal review compares to the technology and telecom reviews multi-facility operators are already used to running.
The average self-storage profit margin is 41 percent. Facilities below 35 percent have specific operating expense categories above market. A strategy call with Craft Enterprises is where we identify which categories are dragging your margin and by how much.
Why Utility Costs Are the Least Reviewed Line Item in Self-Storage
Self-storage operators have gotten disciplined about reviewing technology spend and telecom spend over the past several years. Gate access systems, surveillance connectivity, and internet circuits all get scrutinized because they are visible and tied directly to security. Utility spend does not get the same attention because it feels fixed. Operators assume the rate on the bill is the rate they are stuck with.
That assumption is usually wrong. Utility rates vary by classification, provider, and even by which meter is being billed against which unit. A portfolio with ten facilities can easily have ten different effective rates for the exact same usage pattern, and nobody notices because each bill gets paid individually rather than compared side by side.
What Self-Storage Utility Costs Should Actually Look Like in 2026
Benchmarking self-storage utility costs requires breaking the spend into the categories that actually drive the bill, since a single blended number hides where the waste is.
Electricity: The Largest Self-Storage Utility Cost Category by Facility Size
A standard drive-up facility without climate control typically runs on a fairly light electrical load, covering common area lighting, security cameras, and the gate system. Climate-controlled facilities carry a meaningfully higher load because of HVAC systems running continuously to maintain unit temperature and humidity. Operators comparing their electricity spend against a facility without climate control are comparing against the wrong benchmark entirely.
Water and Sewer Costs for Climate-Controlled Units
Water usage in self-storage is usually minimal outside of restrooms and irrigation, but climate-controlled facilities with humidity control systems can carry higher water costs than operators expect. This is a category almost nobody separates out on the bill review, so it gets absorbed into the general utility line without anyone asking whether it is priced correctly.
Gas and HVAC Costs at Multi-Facility Portfolios
Gas costs concentrate almost entirely around HVAC and, in colder climates, heating for office space and climate-controlled units. Portfolio-wide, this is often the single largest utility category for facilities with climate control, and it is also the category most likely to carry outdated rate classifications, since HVAC load patterns change as buildings age and get retrofitted.
Here is what a self-storage utility cost audit actually reviews against every meter in the portfolio.

The Utility Cost Categories Most Operators Miss
A formal utility bill audit consistently turns up the same handful of issues, portfolio after portfolio.
Outdated rate classifications. Utility providers assign rate classes based on facility type and usage pattern. Facilities get reclassified when local ordinances change or when a provider updates its rate structure, and if nobody flags the change, the facility keeps paying the old, often higher, rate indefinitely.
Vacant unit and closed location billing. Just like the ghost lines that show up in telecom audits, utility accounts for closed facilities or decommissioned meters routinely keep billing for months or years after the location is gone. Nobody catches it because the bill is small enough to pass unnoticed next to the rest of the portfolio spend.
Common area inefficiency. Lighting and HVAC in hallways, offices, and shared spaces often run on outdated timers or manual controls rather than occupancy-based systems, which means facilities are paying to condition and light space nobody is using for large stretches of the day.
Master-metered versus sub-metered discrepancies. Facilities with mixed climate-controlled and standard units sometimes carry billing structures that were set up years ago and never revisited, which can mean one section of a facility is effectively subsidizing another without anyone deciding that on purpose.
Signs Your Self-Storage Portfolio Is Overpaying on Utilities
A handful of patterns show up over and over in portfolios that have never had a formal utility review. None of these signs are dramatic on their own, which is exactly why they go unnoticed for years.
Utility costs that vary widely between similar facilities. If two facilities with comparable square footage, unit mix, and climate control carry meaningfully different utility bills, something in the rate structure, meter setup, or billing classification is inconsistent, and it is worth finding out which one.
Bills that have not changed format in years. Utility providers update rate structures and billing formats periodically. A bill that looks identical to what it looked like five years ago, aside from the total, is a sign nobody has revisited the underlying account setup in a long time.
No documentation of which meter serves which unit or building. Portfolios that have grown through acquisition often inherit utility accounts without a clear record of what each meter actually covers. Without that mapping, it is nearly impossible to know whether a bill is accurate.
Utility spend treated as a single line item rather than broken out by category. Operators who track "utilities" as one number on the P&L, rather than electricity, water, gas, and sewer separately, lose the visibility needed to spot when one category spikes or drifts from benchmark.
How Utility Costs Fit Into Your Full Operating Expense Picture
Utility expense management works best when it is not reviewed in isolation. The same discipline that applies to a telecom expense management audit, tracking every line, flagging every anomaly, and negotiating from a position of full visibility, applies directly to utility spend. Operators who have already gone through a technology lifecycle management review or a telecom audit tend to find the utility review faster and more productive, because the portfolio-wide visibility habit is already built.
At Craft Enterprises, utility expense management sits alongside telecom expense management and IT consulting as one connected review rather than three separate ones. A facility with an outdated utility rate classification often has an outdated telecom contract and an aging IT infrastructure plan sitting right next to it, because they all trace back to the same root cause: nobody has reviewed the full expense picture at the portfolio level in years.
What a Self-Storage Utility Audit Finds
A proper audit starts by pulling every utility bill across every facility and mapping it against current rate schedules, occupancy data, and facility specifications. From there, the review identifies misclassified accounts, billing errors, and consolidation opportunities, then manages the recovery and renegotiation process directly with the providers. Operators typically do not need to change providers to see savings. Most of the recoverable value comes from correcting what is already being billed incorrectly.
The timeline for a full portfolio review generally runs a few weeks from the initial bill collection to a completed findings report, depending on portfolio size and how quickly account access can be established with each provider. Findings are typically organized by facility and by category, so operators can see immediately which locations carry the most recoverable value and prioritize accordingly. For portfolios that have grown quickly through acquisition, this is often the first time anyone has seen the full utility picture laid out side by side rather than buried in a stack of individual bills.
Recovery and renegotiation happen after the findings are confirmed, and this is where a third-party review tends to outperform an internal one. Providers respond differently to a formal audit backed by documented rate discrepancies than they do to a facility manager calling in with a general question about a high bill. The process is built to correct the account going forward and, where applicable, pursue credits for past over billing.
Frequently Asked Questions
How much can a self-storage operator save on utility costs?
Savings vary by portfolio size and how long it has been since the last formal review, but rate corrections, billing errors, and closed-location cleanup consistently represent the largest recoverable categories.
Is climate-controlled storage always more expensive to operate?
Climate-controlled facilities carry higher electricity and gas costs due to continuous HVAC operation, but the increase should be predictable and benchmark-able, not open ended. A cost review establishes what that premium should actually be for a given facility.
How often should a multi-facility operator review utility costs?
An annual review at minimum, with a full audit any time a facility changes ownership, undergoes renovation, or has not been reviewed in more than two years.
Do utility providers ever correct billing errors without an audit?
Rarely. Utility providers are not incentivized to flag overbilling, and most billing systems are not built to self-correct legacy classification errors, which is why the correction almost always has to be initiated by the operator or a third party managing the account.
Can utility expense management be reviewed alongside telecom and IT expenses? Yes, and it is generally more effective when it is. A portfolio-wide expense review that covers utility, telecom, and IT together catches interconnected issues that a single-category review would miss.
What information does a facility need to provide for a utility audit?
Recent utility bills, meter numbers, facility square footage, and climate control specifications are typically enough to begin the review process.
