Start partner setupFDD Item 7 gave you a range for occupancy costs. That range included base rent, NNN obligations, and estimated CAM. You used it to build your pro forma, project unit economics, and decide whether the location penciled out. Then the first reconciliation statement arrived and the number was 40%, 60%, or 100% above the high end of that range.
The gap between FDD projections and actual CAM has two possible explanations. Some of the increase is legitimate: property taxes went up, insurance premiums shifted, the landlord invested in common area improvements. Some of it is not legitimate: the management fee exceeds your lease cap, the pro-rata denominator was manipulated, capital expenses were passed through as maintenance, or excluded charges were billed anyway.
This article breaks down both categories so you can separate the explainable increases from the recoverable overcharges.
FDD Item 7 (Estimated Initial Investment): A table in the Franchise Disclosure Document that lists the estimated costs to open and operate a franchise unit during the initial period. Occupancy costs appear here as a range based on historical data from existing units. These figures are estimates regulated by the FTC Franchise Rule, not guarantees of future costs. The actual occupancy costs are governed entirely by the lease the franchisee signs.
The FDD is a pre-sale disclosure document. The FTC requires franchisors to provide it at least 14 days before any agreement is signed or any payment is made. Its purpose is to enable informed investment decisions.
Three sections of the FDD touch occupancy costs, and each one works differently:
Item 7: Estimated Initial Investment. This is the table franchisees study most closely. It provides low and high estimates for every startup cost category, including rent and occupancy expenses during the initial period (typically the first three months of operation). The occupancy estimate is based on assumptions: a model site type, current market rent rates, and historical NNN charges from existing franchisee locations.
The critical detail is that Item 7 estimates are not forward-looking guarantees. The FTC Franchise Rule (16 CFR Part 436) requires franchisors to have a reasonable basis for each estimate, but "reasonable basis" means historical data, not a binding commitment. If CAM rates rise after the FDD is issued, the franchisor has no obligation to update those estimates until the next annual filing.
Item 11: Franchisor's Assistance, Advertising, Computer Systems, and Training. This section describes what support the franchisor provides for site selection and lease negotiation. Some franchisors approve specific landlords. Some provide a standard lease rider. Some negotiate master lease terms at the system level. What Item 11 rarely discloses is the degree to which the franchisor monitors ongoing CAM charges after opening. In most systems, the franchisee is on their own once the lease is signed.
Item 12: Territory. This section addresses exclusive territories and site approval. It may reference property types (strip center, pad site, enclosed mall) and location requirements, which indirectly affect the range of CAM rates you can expect. A pad site with minimal common area will have lower CAM than an inline unit in a grocery-anchored center.
None of these items bind the landlord. None of them cap your CAM. None of them create recourse if the landlord overbills. The lease does all of that, or fails to.
"I built CAMAudit because the same question kept coming up from franchisees: the FDD said my occupancy costs would be one number, and the reconciliation says another. The FDD wasn't wrong. It just wasn't designed to protect you from what happens after you sign." — Angel Campa, Founder of CAMAudit
Not every increase above the FDD estimate is an overcharge. Understanding the legitimate causes first makes it easier to isolate the illegitimate ones.
County assessors revalue commercial properties on cycles that vary by jurisdiction but typically run every one to five years. A reassessment can increase the property's taxable value by 15-30% in a single year, especially in markets where commercial real estate values have appreciated significantly since the last assessment. Since property taxes are passed through as part of NNN obligations, the tenant absorbs this increase directly.
The FDD estimate was built on tax data available at the time of disclosure. If the property was reassessed between the FDD issuance date and your first full year of occupancy, the increase is real and contractual.
Commercial property insurance premiums have increased substantially in markets exposed to natural catastrophe risk. Coastal properties, wildfire zones, and flood-adjacent areas have seen premium increases of 20-50% in recent renewal cycles according to industry data tracked by the Insurance Information Institute. These increases flow directly through NNN charges.
If the FDD estimate was based on insurance rates from 18 months before your lease commenced, the current rate may bear no resemblance to the estimate.
Landlords invest in common area upgrades: parking lot resurfacing, landscaping redesign, LED lighting conversions, security camera installations, HVAC replacements for shared systems. Some of these are properly classified as operating expenses and belong in the CAM pool. Others are capital improvements that should be amortized over their useful life, not charged in full in the year they occur.
The FDD estimate did not account for these projects because they were not planned when the FDD was prepared. The question is not whether the cost exists, but whether it was classified and allocated correctly.
Item 7 estimates are based on the franchisor's assumptions about a typical location. If your actual site is in a higher-cost property type than the model site (for example, an inline position in a regional center rather than a pad site), the CAM rate per square foot will naturally be higher.
BOMA International and ICSC publish operating expense benchmarks by property type. A neighborhood strip center typically runs $3-7 per square foot per year in CAM. An inline regional mall position can run $8-14 per square foot. If your FDD assumed strip center economics and you signed a regional mall lease, the gap is structural, not an overcharge.
These are the variances that represent recoverable dollars. Each one corresponds to a specific lease provision that was either violated or exploited.
Most NNN leases allow the landlord to charge a management fee as a percentage of total operating expenses. The standard range is 3-5%, and many leases cap it explicitly. The overcharge occurs when the landlord calculates the management fee on a base that includes items the lease excludes from the management fee calculation, or when the percentage applied exceeds the cap.
A franchisee paying $14,000 per year in CAM at a center where the management fee is capped at 4% should see a management fee of no more than $560 (4% of the CAM pool allocated to that tenant). If the reconciliation shows a management fee of $900, the $340 difference is recoverable. For more on how this overcharge works across franchise portfolios, see franchise tenant CAM overcharges.
Your pro-rata share is calculated by dividing your leased square footage by the total leasable area of the property. The overcharge happens when the landlord reduces the denominator by excluding anchor tenants, vacant space, or outparcels. A smaller denominator means each remaining tenant pays a larger share of the same expense pool.
In a 95,000 square foot grocery-anchored center where the anchor occupies 42,000 square feet, the difference between using 95,000 and 53,000 as the denominator changes a 2,200 SF franchise tenant's share from 2.3% to 4.2%. On a $760,000 CAM pool, that is the difference between $9,660 and $17,640 per year.
The FDD estimate almost certainly assumed a pro-rata share based on full GLA. If the landlord is using a reduced denominator, the overcharge will appear as a gap between the FDD projection and actual billing, but the cause is the denominator, not general cost inflation.
A roof replacement, a full parking lot reconstruction, or a major HVAC system installation are capital expenditures. Most leases require these to be amortized over their useful life (typically 10-20 years) rather than charged entirely in the year they occur. When a landlord passes a $180,000 parking lot reconstruction through the CAM pool as a single-year expense, every tenant absorbs their pro-rata share of $180,000 instead of their pro-rata share of an annual amortization payment.
For a 2,200 SF tenant at 2.3% pro-rata: the full pass-through costs $4,140 in one year. Properly amortized over 15 years, the annual cost is $276. The FDD estimate would never have contemplated a $4,140 spike because capital projects were not anticipated in the estimate period. But the issue is not that the cost exists. The issue is that it was classified incorrectly.
Many franchise leases include exclusion lists: categories of expense that are explicitly not included in the CAM pool. Common exclusions include landlord's income taxes, depreciation, leasing commissions, legal fees for landlord disputes, and costs attributable to other tenants' build-outs. When the landlord's accounting team does not apply these exclusions during reconciliation, the excluded costs end up in the pool and get allocated to every tenant.
This type of overcharge is particularly common in franchise locations because the franchisee rarely reads the full reconciliation against the exclusion list in the lease. The statement arrives, the number looks "about right" compared to last year, and it gets paid. For a deeper look at how FDD-level assumptions create blind spots for these overcharges, see why your FDD doesn't protect you from CAM overcharges.
This is a five-step process. It works for a single location and scales to a multi-unit portfolio.
Go back to the FDD you received before signing. Find the Item 7 table and locate the occupancy cost line. Note the low and high estimates. Convert these to an annual per-square-foot figure so you can compare directly against the reconciliation.
Example: if Item 7 estimated monthly occupancy costs (rent plus NNN plus CAM) at $4,200 to $6,800 for a 2,200 SF location, the annual range is $50,400 to $81,600, or $22.91 to $37.09 per SF per year. Strip out the base rent portion (which you know exactly) to isolate the NNN and CAM estimate.
Your landlord should provide an annual reconciliation statement showing the total CAM pool, your pro-rata share percentage, the resulting charge, any monthly estimates you already paid, and the true-up amount owed or credited.
Calculate your actual CAM per square foot per year: total annual CAM charge divided by your leased square footage.
Subtract the FDD estimate (high end) from your actual CAM per square foot. If your FDD estimated CAM at $6.50/SF and your actual reconciliation shows $11.20/SF, the delta is $4.70/SF, or $10,340 annually on 2,200 SF.
That $10,340 is the total gap. Not all of it is recoverable, but all of it deserves explanation.
Go through the reconciliation line by line and sort each variance into one of two buckets:
Explainable increases (not recoverable): property tax reassessment, insurance premium increase, legitimate new operating expenses within the lease definition of CAM.
Potential overcharges (recoverable): management fee above the lease cap, pro-rata share calculated on a reduced denominator, capital expenses not amortized, excluded services billed, administrative charges without lease basis.
For each item in the "potential overcharge" bucket, go to the specific lease clause that governs that cost. Check whether the management fee percentage matches the cap. Check whether the denominator matches the lease definition. Check whether capital expense amortization language exists and was followed. Check the exclusion list against the charges in the pool.
If you do not have the time or expertise to complete this lease-by-lease comparison, upload your reconciliation and lease to CAMAudit. The platform runs each of these checks automatically and flags the specific clauses that apply.

Franchisees sometimes assume the franchisor is the right first call when occupancy costs spike. That depends on what caused the increase.
Benchmarking across the system. If you operate five locations and one of them has CAM that is 60% higher per square foot than the others in similar property types, the franchisor's real estate team may have data from other franchisees in the same center or market. They can confirm whether your CAM is an outlier.
Lease renewal negotiation. Some franchisors provide lease negotiation support or approved lease riders that address CAM caps, management fee limits, and audit rights. If your current lease is weak on CAM protections, the franchisor may help strengthen those provisions at renewal.
Site approval context. The franchisor's real estate team approved your site based on projected occupancy costs. If those costs have diverged significantly from the approval assumptions, the franchisor has an interest in understanding why, especially if the same pattern is affecting other franchisees in the same center.
Reconciliation disputes. Your lease is between you and the landlord. The franchisor is not a party to it. If the management fee exceeds the lease cap, if the pro-rata denominator is wrong, or if excluded charges appear in the CAM pool, those are lease violations. The dispute is with the landlord, not the franchisor.
Audit rights exercise. Your right to inspect the landlord's books comes from the lease. The franchisor cannot exercise it on your behalf unless they are a party to the lease or have specific contractual authority to do so.
Dispute letter drafts. If the audit identifies recoverable overcharges, the formal dispute communication goes to the landlord or their property management company. The franchisor should be informed (since the outcome may benefit other system tenants in the same property), but the claim is yours to make.
For franchisees who need a deeper understanding of NNN lease structures, that context helps clarify which costs are within the landlord's billing authority and which fall outside it.
Are FDD Item 7 occupancy cost estimates legally binding?
No. FDD Item 7 provides estimated ranges for the initial investment, including occupancy costs. These estimates are regulated by the FTC Franchise Rule and must have a reasonable basis, but they are not guarantees. The actual occupancy costs are governed by the lease you sign with the landlord, not the FDD.
Why is my actual CAM so much higher than the FDD estimate?
The gap has two categories of causes. Legitimate increases include property tax reassessments, insurance premium changes, and new operating expenses within the lease definition of CAM. Illegitimate increases include management fee overcharges above the lease cap, pro-rata denominator manipulation, capital expenses passed as current-year maintenance, and excluded charges billed to the CAM pool.
Can my franchisor dispute CAM overcharges on my behalf?
Generally no. The lease is between you and the landlord. Your franchisor is not a party to the lease unless they signed as a guarantor or co-tenant. The franchisor can provide benchmarking data and lease negotiation support, but the formal dispute is between you and the landlord or their property management company.
How do I know if a CAM increase is an overcharge or a legitimate cost change?
Compare each line item in the reconciliation against the specific clause in your lease that governs it. Check whether the management fee percentage matches the lease cap. Verify the pro-rata denominator matches the lease definition of total leasable area. Confirm capital expenses are amortized per the lease terms. Review the exclusion list against what was billed. Any charge that violates a specific lease provision is a potential overcharge.
What is my deadline to dispute CAM charges after receiving the reconciliation?
Most NNN leases include an audit rights clause that sets a window, typically 12 to 24 months from receipt of the annual reconciliation statement, during which you can contest charges. Once that window closes, the charges are generally considered final regardless of accuracy. Check your lease for the specific deadline at your location.
