A storage charge is on the bill. You do not remember a cage. You flip through the stack of lease addenda tucked in the back of your folder, running a finger down each fee schedule to cross-reference the line item that popped up on this month’s operating cost reconciliation. The charge is $182, labeled “shared ground-floor storage cage access,” and no part of your signed lease terms mentions this specific amenity or associated cost. You pull your signed original lease out of its envelope to compare the listed operating expense categories directly against the invoice line, so you can resolve the discrepancy before the bill’s due date.
Identify Both Relevant Lease and Invoice Line Items
You start by isolating the two core lines that frame this discrepancy, plus a cross-check of all signed supporting documents, to create a clear side-by-side comparison that eliminates any ambiguity about your obligations. You don’t need to dig through decades of old building records to validate the mismatch; the only documents that matter here are the ones you signed when you leased the space, and the current invoice you received. If you find a reference to a storage fee in an unsigned addendum or a building rules document that was handed to you after you signed the lease, that does not count as an agreed-upon obligation, since you never signed to acknowledge the fee.
| Line Item Label | Source Document | Exact Language | Assigned Cost Responsibility |
|---|---|---|---|
| Lease Operating Expense Line | Signed commercial lease, page 17, section 4.2 | “Tenant shall pay pro rata share of building operating expenses limited to common area maintenance, property insurance, property tax, and contracted security services” | Tenant only pays for explicitly listed expense categories |
| Invoice Storage Cage Line | Current month operating cost reconciliation, line 12 | “Shared storage cage access fee, prorated across all ground-floor tenants” | Landlord assigned to tenant without written addendum or prior agreement |
| Addendum Cross-Check Line | All signed lease addenda on file | “No provisions referencing storage facilities, access fees, or unlisted operating expense add-ons appear in any executed document” | No enforceable obligation for tenant to pay the listed charge |
When reviewing these line items, confirm that any pro rata calculation aligns with the share outlined in your lease, which is almost always tied to the percentage of the building’s total rentable square footage your space occupies. Illustrative example: If your 1,200 square foot space makes up 4% of the building’s total rentable area, any valid operating expense charge would be 4% of the total building cost for that line item, so a $4,000 total annual security contract would add $13.33 to your monthly bill, which aligns with the explicitly listed categories in your lease. The storage cage fee, by contrast, has no corresponding line in the lease’s approved expense list, so even if the pro rata calculation is mathematically correct, it is not tied to an obligation you agreed to.
Flag the Controlling Provision for Operating Expenses
You now mark the specific section of your signed lease that lists the limited operating expenses you are required to pay, as this is the controlling document for all cost obligations tied to your space. You can highlight that section with a yellow marker, and write a note in the margin that references the invoice date and the storage cage line item, so anyone reviewing the lease later can immediately connect the discrepancy. You do not need to make any permanent edits to the original lease, just add marginal annotations that are clearly dated and tied to the specific invoice in question. If you have a digital copy of the lease, you can add a comment linked to that section of the document that includes a photo of the invoice line item, for easy reference when you follow up with your property manager.
You should also highlight the clause in your lease that states no modifications to the lease are valid unless they are in writing and signed by both you and your landlord, which almost every standard commercial lease includes. That clause backs up your position that an unagreed-upon fee added to an invoice does not create a new obligation for you to pay. You can reference this clause directly when you reach out to your property management team to question the charge, to frame your request for removal around the explicit terms you both signed.
Store This Annotated Page With Your Primary Lease File
You keep this side-by-side comparison and the marked lease section in the same folder as your original lease, all other signed addenda, and past operating expense reconciliations, so you don’t have to hunt for the details if the charge appears on future invoices. If you use a digital lease management system, you can upload a scanned copy of this annotated page to Lease Jacket for cloud backup alongside your core lease documents. Make sure you also save a copy of the email or written message you send to your property manager, so you have proof that you notified them of the discrepancy before the invoice due date. Most leases require you to notify your landlord of operating expense errors within a set window, so sending that note as soon as you spot the discrepancy protects you from being held responsible for the fee just because you did not flag it quickly enough.
You should file a physical copy in your on-site file and store a second digital copy in a cloud folder that you can access from any device, in case your physical file is lost or damaged. You can also attach a copy of the note you send to your property manager questioning the charge, so you have a full paper trail of your dispute that is easy to pull up if the issue escalates or the charge reappears in later billing cycles.
The Next Time You Open This Page
When you come back to this page, you will have already followed up with your property manager to share the side-by-side comparison and ask for the charge to be removed from your next bill. You can use the blank space at the bottom of this page to jot down notes from your conversation with the property team, including whether they agreed to reverse the charge, if they provided any documentation of a previously unshared addendum, or if they plan to add the charge to future invoices. If the charge is reversed, you can mark the page as resolved, file it with your paid invoice for the month, and reference it if any similar unapproved charges appear in future reconciliations.
You can also use this page to note if the property team explains that the charge is a mistake that will be corrected across all tenant invoices, or if they state that the storage cage is a new amenity that they are rolling out for optional use. If the amenity is optional, you can note whether you choose to opt in and pay the fee, or opt out and request that the charge be removed permanently from all future bills. If you do choose to opt in, you can attach a copy of the signed addendum reflecting that new agreement to this page, so your record is complete. If the property team pushes back on removing the charge, you can use this page to track all subsequent communications about the fee, so you have a clear timeline of the discrepancy if you need to reference it during lease renewal negotiations or when working with your commercial real estate broker to adjust future terms.
