Catching a Landlord's Operating Cost Errors Before Lease Renewal

The situation

Eun-ji and Hyun-woo opened their salon in a mid-rise commercial block five years earlier, on a lease with two renewal options. The business had grown steadily — from one chair and a part-time receptionist to a full floor with six stylists and revenue that had climbed past $600,000 a year. Eun-ji kept the books herself, a habit from her earlier career as a bookkeeper, and Hyun-woo ran the floor. Between them they had a good instinct for when numbers looked wrong, even before they could say exactly why.

With the lease's first renewal option coming due, the landlord's property manager, Selam, sent over a package: a renewal offer at a higher base rent, plus the usual notice that "additional rent" — the tenant's share of the building's operating costs, billed on top of base rent — would also be adjusted going into the new term. Eun-ji pulled the last two years of reconciliation statements, the annual documents landlords send showing actual costs versus the estimates tenants had been paying monthly, to compare against what the salon had actually paid. The additional rent line had grown by close to 40 percent over two years, well ahead of anything she could explain from rising utility or cleaning costs alone. Before agreeing to a renewal rate built on top of those numbers, the two owners brought the lease and the statements to Treadstone Law for a contract hygiene review — a check of whether the paperwork actually said what everyone assumed it said, and whether the landlord had been billing accordingly.

What the review found

Commercial leases define "operating costs" in a specific clause, usually with a list of what counts and, just as importantly, what is excluded. The distinction matters because operating costs are meant to cover the day-to-day running of the building — cleaning, utilities, routine repairs, property management fees — recovered from all tenants in proportion to the space they occupy. Capital expenditures, the cost of replacing major building systems or structural elements, are treated differently. Most leases either exclude them entirely from the operating cost pool or require them to be amortized, spread out over the useful life of the improvement, rather than charged in full in the year the work happens.

Reading the salon's lease against the two reconciliation statements, our team found three problems. First, the prior year's statement included the full cost of a roof section replacement, charged in one lump sum to that year's operating cost pool. The lease's own definition excluded capital repairs of that kind from the recoverable pool altogether — the building's owner was meant to absorb that cost, not spread it across tenants. Second, the management fee — typically calculated as a fixed percentage of operating costs under a cap set out in the lease — had been calculated on a base that included the disputed roof cost, inflating the fee itself along with everything else. Third, the lease had a gross-up provision, a standard mechanism that adjusts variable costs like utilities and cleaning as if the building were fully occupied, so that a partially empty building doesn't leave remaining tenants covering vacant units' share. The building had run below full occupancy for part of the relevant year, but the reconciliation statement showed no gross-up adjustment at all, meaning the salon and other tenants were absorbing costs that should have fallen on the vacant units' account instead.

None of these were the kind of error a tenant would catch without pulling the lease's actual definitions and doing the arithmetic. The statements themselves looked routine — a total, a percentage share, an amount owing. The problem was invisible unless someone checked the total against what the lease said should be in it.

What we did

1. Confirmed the audit right and its window. Most commercial leases give tenants a right to review or audit the landlord's supporting records for a reconciliation statement, but only within a set period after the statement is issued. The salon's lease gave a window that had already closed on the older of the two statements but was still open on the more recent one, which set the scope of what could formally be challenged.
2. Requested the backup documentation. We sent a written request under the lease's audit provision for the invoices and cost breakdowns supporting the current year's reconciliation, rather than relying on the summary figures the salon had already received.
3. Recalculated the pool against the lease's own definitions. Line by line, we separated what the lease's operating cost clause actually permitted from what had been billed, isolating the roof capital cost, the inflated management fee calculated on top of it, and the missing gross-up adjustment.
4. Quantified the overcharge. The roof cost and its knock-on effect on the management fee came to roughly $9,000 in charges that should never have entered the pool. The missing gross-up adjustment accounted for a further $5,000 in costs that should have been allocated to vacant units rather than paying tenants. Together, the overcharge for the year came to about $14,000.
5. Sent formal written notice to the landlord. The notice set out the specific clauses relied on, itemized the discrepancy, and requested a corrected reconciliation and a credit for the overcharge, timed to arrive before the renewal terms were finalized so the two issues could be resolved together rather than as a separate dispute after signing.
6. Negotiated the resolution alongside the renewal. Rather than treating the audit finding and the renewal offer as separate conversations, we folded both into discussions with Selam, giving the landlord a practical reason to resolve the overcharge cleanly rather than risk delaying a renewal it also wanted to close.

The outcome

The landlord's head office reviewed the figures and agreed with the corrected calculation within a few weeks, without the matter needing to go further. Rather than a cash refund, the roughly $14,000 overcharge was applied as a credit against the salon's rent for the first months of the new lease term, which suited both sides and avoided a separate payment process. The corrected reconciliation methodology — excluding capital costs from the pool and applying the gross-up adjustment properly — was confirmed in writing as the basis for future years, so the same error would not simply repeat itself under the new lease.

The renewal itself was negotiated with a clearer picture of the real cost base going forward, since Eun-ji and Hyun-woo were no longer pricing their next five years around numbers that were partly wrong. The new lease also tightened the operating cost definition slightly, adding a specific line stating that capital repairs of the kind at issue would be excluded, which reduced the room for the same kind of ambiguity to produce another dispute later.

For the salon, the exercise did two things at once: it recovered a specific, quantifiable overcharge, and it changed how the business would read its lease paperwork going forward. Eun-ji began setting a standing reminder to compare each year's reconciliation statement against the lease's definitions before the audit window closed, rather than assuming the landlord's numbers were self-evidently correct.
