What CAM exclusions should every commercial tenant negotiate?

The non-negotiable tier includes: capital expenditures (or require amortization over useful life), executive and corporate overhead salaries, leasing commissions and marketing costs, depreciation, ground rent and mortgage financing costs, costs of tenant improvements for other tenants, and fines or penalties. These categories represent both the highest dollar risk and the categories most landlords in competitive markets will concede. If you can only negotiate a few exclusions, start here.

How do you negotiate CAM exclusions with a landlord who says their form is non-negotiable?

Every landlord says their form is non-negotiable until there's a lease they want to sign. Start with the high-probability concessions — things the landlord is unlikely to have billed anyway (depreciation, fines, ground rent). Getting those in writing costs the landlord nothing but creates protection for you. Then move to the moderate-resistance categories: cap on management fee, amortization requirement for capex, and exclusion of corporate overhead. Save the hard fights (anchor exclusions, full capex exclusion) for where you have the most leverage.

What's the dollar value of negotiating a CAM exclusion list?

It depends heavily on the property and how the landlord operates it. For a 20,000 sf tenant in a 200,000 sf building paying $7/sf CAM ($140,000 annually), a well-negotiated exclusion list that eliminates 10% of the billed amount (not unusual) saves $14,000/year — $140,000 over a 10-year lease. The ROI on negotiation time is extremely high, particularly for larger tenants.

Are CAM exclusions enforceable after the lease is signed?

Yes — exclusions written into the lease are contractually binding. They're enforceable through audit rights (you review to confirm excluded items weren't billed) and through the dispute resolution mechanism if they were. The challenge is that landlords sometimes include excluded items anyway, betting that tenants won't audit. This is why audit rights and exclusion lists need to be negotiated together — the exclusion list tells you what to look for; the audit rights give you the mechanism to recover.

Do CAM exclusions differ between retail and office leases?

Yes, significantly. Retail leases (especially in shopping centers) tend to have more complex exclusion lists because the expense pools are larger and more varied. Office leases often have cleaner expense pools but can include building-wide services that retail leases don't. Industrial leases tend to have the simplest CAM structures — often just maintenance, insurance, and taxes. The categories in this guide apply broadly, but their relative priority and the landlord's resistance to them varies by property type.

CAM Exclusions Negotiation Guide: 30 Categories Tenants Should Push For

By Angel Campa·Founder, CapVeriUpdated April 24, 2026

Quick Answer

CAM exclusion negotiation is about getting explicit lease language that removes specific expense categories from the operating expense pool you're responsible for. The 30 categories in this guide range from universally accepted exclusions (landlords almost never push back) to heavily contested ones. Every dollar you exclude from the pool compounds over the lease term — a $50,000 annual exclusion over 10 years saves $500,000 in CAM payments.

CAM Exclusions: Why the Negotiation Matters

When you sign a commercial lease, the operating expense language determines your exposure for the entire lease term. A broadly defined expense pool with no exclusion list can include almost anything the landlord wants to charge. A well-negotiated exclusion list puts a fence around the costs you'll share.

Tenants who negotiate exclusions at signing don't need to fight as many audit battles later. The exclusion list does the filtering work in advance.

Here's how to prioritize the negotiation and what to expect from each category.

Tier 1: Universally Accepted Exclusions

These categories almost never generate landlord pushback in competitive markets. If a landlord resists these, reconsider the deal.

1. Depreciation and amortization of the building itself Landlords own the building. They get the depreciation deduction on their taxes. Having tenants fund it again through CAM is double recovery. Any landlord who resists this exclusion is either unsophisticated or aggressive.

2. Mortgage principal, interest, and financing costs Your rent covers the landlord's debt service. Charging financing costs through CAM is rare but documented — make sure it's excluded explicitly.

3. Ground lease payments If the landlord is a ground lessee rather than the fee owner, their ground rent is their cost of doing business, not an operating expense of the building.

4. Income taxes, excess profits taxes, and corporate franchise taxes Taxes on the landlord's income or corporate structure. You pay real estate taxes on the property; you don't pay the landlord's income taxes.

5. Fines, penalties, and late charges If the landlord violates a code, permit requirement, or lease obligation and incurs a fine, that's their problem. Make sure it's explicitly excluded — otherwise, a regulatory violation fine could theoretically appear as an operating expense.

6. Costs of correcting defects in the original construction The building should have been built correctly to begin with. Costs to correct original construction defects are the developer's or contractor's liability, not the tenant's.

7. Legal fees related to landlord-tenant disputes Legal costs to enforce leases, evict tenants, or pursue other tenants are the landlord's business expense. They should not be pooled across tenants.

8. Costs of environmental remediation Pre-existing environmental conditions or landlord-caused contamination. You don't want to fund cleanup of a problem you didn't create.

Tier 2: Standard Exclusions in Most Negotiated Leases

These categories require a request and some negotiation, but most institutional landlords in markets with tenant leverage will accept them.

9. Executive and corporate overhead salaries On-site property manager salaries are typically includable. The VP of Real Estate's salary, corporate accounting staff, and regional managers who oversee multiple properties are not. Language: "Salaries of personnel not engaged in the direct management and operation of the Property."

10. Leasing commissions and brokerage fees Costs of finding and placing tenants — commissions, referral fees, tenant inducements — are the cost of owning a building, not operating it. Exclude explicitly: "leasing commissions, brokerage fees, finder's fees, and referral fees."

11. Tenant improvement costs for other tenants Buildout costs for other tenants' spaces. Sometimes appears in CAM as "renovation" expenses. Language: "Costs of tenant improvements or alterations made for the exclusive benefit of any other tenant."

12. Marketing and advertising costs for the property Leasing brochures, broker events, signage for vacant space — these benefit the landlord's leasing effort, not building operations. Retail common area promotions are typically different (and often separately billed as "merchants association" fees).

13. Capital expenditures (with amortization carve-out) Full exclusion is ideal. More commonly negotiated: "Costs of capital improvements, except that costs of capital improvements required by governmental authority or made to reduce operating expenses may be included, amortized over their useful life not to exceed IRS guidelines." The key word is "amortized" — current-year billing of multi-year improvements is a common overbilling pattern.

14. Insurance proceeds and warranty recoveries If the landlord receives insurance money or warranty payments for a repair and still billed the repair to CAM, you've paid twice. Language: "Costs to the extent actually recovered through insurance proceeds, warranties, or from other tenants."

15. Costs attributable to properties other than the Property For landlords who own multiple properties, ensure portfolio-wide costs (insurance, management overhead, accounting software, legal retainers) aren't allocated to your property. Language: "Costs allocated from or shared with any other properties owned or managed by Landlord or its affiliates."

Tier 3: Negotiable with Leverage

These categories require meaningful leverage — a competitive market, a large tenancy, or a landlord who really needs to fill the space.

16. Capital expenditures — full exclusion Some leases completely exclude all capital expenditures, not just require amortization. This is achievable in strong tenant markets or for large tenants. Landlords in weak markets resist because capex (HVAC systems, elevators, roofs) is a real building cost they want to share.

17. Management fees on gross revenues Negotiate the base from gross revenues to operating expenses only. If the landlord won't change the base, negotiate the cap rate down (3% instead of 5%). See CAM charges cap limits explained for how fees interact with caps.

18. All costs of any renovation, restoration, or expansion project Not just tenant improvement work — all renovation costs during major projects. This protects you if the landlord undertakes a building-wide renovation that increases operating expenses temporarily.

19. Costs related to the sale or refinancing of the property Due diligence costs, legal fees for financing transactions, transfer taxes (where applicable). Occasionally appears in operating expenses during an ownership transition.

20. Charity contributions and entertainment Rare but documented. Exclude explicitly to be safe: "Charitable contributions, political donations, and entertainment expenses."

21. Cost of artwork, decorative items, and lobby improvements Lobby renovations and art programs sometimes appear in operating expenses. Exclude: "Costs of artwork, decorative furnishings, and non-functional lobby improvements."

22. Costs related to co-tenancy failures In retail leases, co-tenancy provisions give tenants rent reductions when major tenants leave. If the landlord incurs costs trying to satisfy co-tenancy obligations (finding replacement anchors, offering inducements), those shouldn't hit CAM.

23. Technology infrastructure — landlord's internal systems Landlord's property management software, IT infrastructure for leasing operations, and similar systems. Property-level operational technology (building management system, security cameras) is more defensible as an operating expense.

24. Excessive management fee — no-double-billing Not an exclusion of the fee itself, but a prohibition on charging both a management fee and a separate administrative surcharge for overlapping services. Language: "Management fee shall be in lieu of, and not in addition to, any administrative or overhead charge for the same services."

25. Landlord's profit on self-provided services Some landlords own affiliated service companies (janitorial, HVAC, parking management). Exclude profit markups: "Costs of services provided by affiliates of Landlord shall not exceed the market rate for comparable services in the market."

Tier 4: High-Resistance, High-Value Exclusions

These categories represent the most significant financial protection but meet the most landlord resistance.

26. Anchor tenant exclusion adjustment In retail centers where anchor tenants pay reduced or no CAM, the denominator should still include anchor space so other tenants' shares aren't inflated. See anchor exclusion CAM guide for the mechanics.

27. Gross-up cap at 95% Limits the gross-up calculation so that variable expenses can never exceed what they'd be at 95% occupancy — preventing artificially inflated expense pools in buildings that never achieve full occupancy.

28. Operating expenses cap (overall) A hard dollar cap on total CAM charges, independent of the controllable expense cap structure. Landlords almost never agree to this because it eliminates their ability to pass through real cost increases.

29. Exclusion of all real estate tax increases above CPI Limits tax pass-throughs to CPI-level increases, leaving extraordinary assessment increases with the landlord. Difficult to negotiate but protects against sudden reassessments in jurisdictions with volatile tax environments.

30. Staffing cost exclusions above defined ratios Property staffing costs capped at a defined ratio (e.g., hours per 10,000 sf, or a capped dollar amount per year). Prevents landlords from over-staffing and billing the costs to tenants.

Prioritization Framework

You can't negotiate all 30, and pushing too hard on every item can derail the deal. Prioritize by:

Dollar impact x Probability of occurring x Probability of landlord accepting

Category	Dollar Impact	Probability of Billing	Landlord Acceptance	Priority
Capital expenditures (amortization)	High	High	Moderate	1
Management fee base and cap	High	Certain	Moderate	1
Executive/corporate overhead	Medium	Moderate	High	1
Leasing commissions	Medium	Moderate	High	2
Gross-up cap	High	High (variable occupancy)	Moderate	2
Affiliate service markups	Medium	Moderate	Low	3
Technology/systems costs	Low	Low	High	3

Start with the Tier 1 items (they're free to get) and the top items from the prioritization framework. Accept that you won't win everything, and save your capital for the provisions with the highest dollar impact.

For context on how exclusions interact with cap protections, see CAM cap calculation guide and cumulative vs non-cumulative CAM caps. Once you're in a lease with a defined exclusion list, use the tenant lease audit checklist to verify those exclusions are being honored.
