CAM Reconciliation
CAM reconciliation is the annual true-up between the estimated common area maintenance (CAM) charges a tenant paid during the year and the tenant’s actual share of what the landlord spent. If estimates ran below actuals, the tenant owes the difference; if above, the tenant receives a credit or refund. The lease — caps, exclusions, gross-up language, pro-rata definitions — controls every number in the calculation.
How the reconciliation works
During the year, tenants pay monthly CAM estimates set by the landlord. After year-end, the landlord totals actual operating costs for the property, removes expenses the lease excludes, applies any gross-up, allocates each tenant its pro-rata share, applies any cap, and compares the result to what the tenant actually paid. The statement showing this math is the reconciliation, typically due to tenants within 90–120 days of year-end.
Every step of that chain is a lease term, not a convention. Two tenants in the same building can owe different CAM on identical square footage because one lease excludes capital expenditures and caps controllable costs at 5% annual growth while the other does neither. This is why CAM disputes are rarely arithmetic disputes — they are lease-language disputes.
The clauses that decide the outcome
- ✓Pro-rata share definition: leased area over leased-and-occupied area versus total leasable area changes the denominator — and the bill
- ✓Exclusions list: capital items, structural repairs, leasing commissions, and ownership costs are commonly excluded; the exact list varies per lease
- ✓Caps: a 5% cap on controllable CAM growth, cumulative vs non-cumulative, compounding vs base-year — small wording changes swing five-figure amounts over a term
- ✓Gross-up clauses: in partially vacant buildings, variable costs are grossed up to a stipulated occupancy (commonly 95%) so per-tenant shares stay stable
- ✓Audit rights: the tenant’s right to inspect the landlord’s books, its deadline, and whether audit costs shift on discovered overbilling
Why CAM lives or dies on the lease abstract
Reconciliation season is where bad abstraction gets expensive. If the abstract missed the cumulative cap language in the third amendment, the landlord over-bills (or under-bills) every year until someone re-reads the lease — usually a tenant’s auditor. For property managers on Yardi or MRI, the recovery setup in the ERP is only as good as the abstract it was keyed from: cap type, base year, exclusions, and gross-up percentage all live as structured recovery fields.
Our abstraction pipeline captures the full recovery picture — caps with their exact type, exclusion lists, gross-up language, audit windows — with page citations, so the numbers your ERP bills are the numbers the lease supports.
Frequently asked questions
What does CAM include?
Typically: maintenance and repair of common areas, landscaping, parking-lot upkeep, snow removal, common utilities, property-level insurance, management fees, and sometimes property taxes (or those travel separately in a triple-net structure). What CAM includes for a given tenant is whatever that tenant’s lease says — the exclusions list is where most negotiation happens.
When are CAM reconciliations due?
Most leases require the landlord to deliver the annual reconciliation statement within 90–120 days after the calendar or fiscal year ends. Some leases make deadlines binding: deliver late and the landlord waives the right to collect a shortfall for that year.
What is a CAM gross-up?
A clause letting the landlord scale variable operating costs to a stipulated occupancy (commonly 95%) before allocating shares. In a half-empty building, actual cleaning costs are low but concentrated on few tenants; grossing up keeps each tenant’s share at what it would be in a stabilized building. Only variable costs may be grossed up — applying it to fixed costs is a classic overbilling pattern audits catch.
What is the difference between cumulative and non-cumulative CAM caps?
A non-cumulative cap limits each year’s increase independently (5% over last year’s actual). A cumulative cap grows the ceiling by 5% per year from a base — unused headroom carries forward. Over a 10-year term the two produce very different totals, and the distinction often hangs on a single word in the clause, which is why abstracts must quote cap language exactly.
