Laundromat CAM Charges and Percentage Rent: Auditing What You Owe
Laundromat CAM charges are frequently larger than tenants expect and are almost never checked. They are computed by the landlord, reconciled annually, and most leases give a tenant the right to review the calculation within a window that quietly expires. Auditing one reconciliation often pays for years of attention.
Key takeaways
- Rarely examined and frequently wrong, usually through mundane error rather than intent.
- The audit window is short and expires quietly — diarise it from the date the reconciliation arrives.
- Capital items in an operating charge are the most common and most valuable finding.
- Percentage rent turns on the definition of gross sales, especially service and vending revenue.
- It reduces the sale price at a multiple, because occupancy cost comes out of the earnings.
What Is Actually in a CAM Charge?
The tenant's proportionate share of operating the shared parts of the property, and the list is longer than most tenants realise.
| Category | Typically included | Worth checking |
|---|---|---|
| Parking lot maintenance and lighting | Yes | Resurfacing may be capital, not operating |
| Landscaping and snow removal | Yes | Frequency and contractor pricing |
| Common area utilities | Yes | Whether any tenant-specific use is bundled in |
| Property management fee | Usually | Whether the percentage is capped |
| Insurance on the structure | Often | Whether it duplicates cover you carry |
| Property taxes | Often, in a triple-net lease | Whether reassessment was passed through correctly |
| Roof and structural repair | Varies, and disputed | Frequently capital rather than operating |
| Administrative fee on top | Sometimes | Whether the lease permits it at all |
Two of those rows account for most disputes. Capital versus operating is the big one: replacing a roof or resurfacing a car park is usually a capital improvement with a long life, and passing its full cost through in one year's operating charge is a common and expensive error. And the administrative fee, which some leases permit and many do not.
Why Is This Number So Rarely Checked?
Because of how it arrives, and because of who has the information.
The landlord computes it from their own records. It arrives as a reconciliation — a total, a proportionate share, and a balancing figure — usually months after the year it covers. It looks official, it is one number among many, and checking it requires requesting documentation that has to be asked for specifically.
Meanwhile the tenant is running a laundromat. The reconciliation lands in a pile with the utility bills, and the audit window in the lease runs while nobody is looking at it.
That is the whole mechanism. There is rarely anything improper happening — landlords make ordinary accounting decisions, some of which are wrong in the tenant's favour and some of which are not, and nobody checks either way.
The consequence is that a tenant who does check is doing something unusual, and unusual attention frequently finds something. Not always, and often enough that one audit pays for the habit.
How Do You Audit a Reconciliation?
Six steps, in order, and the first is the one with a deadline attached.
Diarise the audit window the day the reconciliation arrives. Most leases give a defined period — sometimes as short as thirty or sixty days — to raise a query or request documentation. Missing it usually means accepting the figure.
Read what the lease actually permits. Which categories may be charged, which are excluded, whether capital items are excluded explicitly, whether an administrative fee is allowed, and whether any cap applies.
Request the supporting documentation, in writing, referencing the lease provision that entitles you to it. Invoices and a breakdown by category, not just a summary.
Check the denominator. Your proportionate share should be computed on the basis the lease specifies — usually your square footage over the property's leasable area. Confirm which figure they used, because vacant space and anchor tenants with negotiated exclusions change the arithmetic materially.
Look for capital items. Resurfacing, roof replacement, HVAC replacement, structural work. These are the highest-value findings.
Compare year on year by category. A line that jumped sharply has a reason, and asking for it is a reasonable question rather than an accusation.
Where you find something, raise it factually and in writing, citing the lease and the document. Most of these resolve as corrections rather than disputes.
What About Percentage Rent?
Uncommon in small retail leases, and it appears often enough to be worth reading for.
The provision requires additional rent once gross sales pass a threshold. Where it exists, three things matter far more than the percentage.
The definition of gross sales. This is where the money is. Does it include wash-and-fold and other service revenue? Vending? Soap sales? Amounts refunded to customers? A broad definition applied to a laundromat that later adds a service line can produce an obligation the tenant never contemplated when they signed.
The breakpoint, and whether it is natural or stated. A breakpoint set years ago against a different business plan may be reached far sooner than either party expected.
The reporting obligation. Percentage rent provisions usually require the tenant to report sales, sometimes with a right for the landlord to audit. That is a records requirement with its own consequences.
For a laundromat specifically, the risk to watch is expansion. A store that adds wash-and-fold, pickup and delivery, or commercial accounts can cross a breakpoint on revenue that carries much thinner margins than the coin business the breakpoint was set against.
What Does This Do to the Store's Value?
It comes out of the earnings, and earnings get multiplied.
Occupancy cost — base rent plus CAM plus any percentage rent — is deducted before the figure a buyer applies a multiple to. So an overstated CAM charge does not cost you its annual amount; it costs that amount times the multiple, every year it persists and again at the exit.
That reframes the audit. Recovering a modest annual overcharge is worth having. Correcting a recurring overstatement before a sale is worth several times more, because the corrected figure is the one that gets multiplied.
Two practical consequences.
For an owner planning an exit, audit the reconciliation two or three years out rather than in the final year. A corrected charge needs to appear in the trailing figures a buyer will examine, and one year of clean numbers is less persuasive than three.
For a buyer, occupancy cost belongs in diligence alongside utilities. Ask for the last three reconciliations, check the categories against the lease, and confirm what the charge has done year on year. A charge that has been rising faster than inflation is a cost you are inheriting, and it is worth understanding why before you price the store.
Summary
CAM charges are computed by the landlord, arrive months late, and are checked by almost nobody — which is exactly why checking finds things. The errors are usually mundane: a capital item in an operating charge, a proportionate share on the wrong denominator, or a fee the lease does not permit.
Diarise the audit window, read what the lease actually allows, request the documentation, and check the denominator. Where percentage rent exists, read the definition of gross sales before adding any service line. And do it well before a sale, because occupancy cost is deducted from the earnings a buyer multiplies — which makes a recurring overcharge considerably more expensive than its annual figure suggests.
The Next Step
Frequently Asked Questions
What are CAM charges?
Common area maintenance charges are the tenant's share of operating the shared parts of a property — parking, lighting, landscaping, snow removal, management and often insurance and taxes. They are billed alongside base rent and are frequently a larger and less examined number than tenants expect.
Why are they so often wrong?
Because they are calculated by the landlord from their own records, reconciled annually, and rarely checked. Errors are usually mundane rather than deliberate: a capital item categorised as an operating expense, a proportionate share computed on the wrong denominator, or a cost that the lease excludes.
Can I actually audit them?
Most commercial leases give the tenant a right to review the reconciliation and supporting documentation, within a defined window after it is issued. That window is often short, which is the single most common reason the right goes unused.
What is percentage rent?
A provision requiring the tenant to pay additional rent above a threshold of gross sales. It is uncommon in small retail leases and it does appear, and where it exists the definition of gross sales matters enormously — particularly whether it includes service revenue or vending.
Does this affect what my store is worth?
Yes, through the earnings. Occupancy cost comes out before the earnings a buyer multiplies, so an overstated CAM charge reduces the sale price by its amount times the multiple. That is why auditing it is worth more than the annual refund suggests.
When is the best time to fix it?
At a renewal or an assignment, when the lease is open and the landlord is engaged. Caps on controllable charges, a clear exclusion list and workable audit rights are all far easier to obtain then than mid-term.
