CAM (Common Area Maintenance) charges show up on almost every NYC retail lease, and they're one of the most consistently mishandled parts of the deal. Tenants who focus only on the base rent and ignore the CAM language often end up paying meaningfully more than they expected. Brokers who don't push back on CAM clauses on behalf of their clients leave money on the table. And the variation in CAM structures across NYC landlords is wide enough that what's standard in one building is a giveaway in another.
This is the working broker's read on CAM in 2026: what it actually covers, how the numbers shake out, and the specific clauses worth fighting on.
CAM (Common Area Maintenance) charges in NYC retail leases are tenant reimbursements for the landlord's costs of operating shared building areas, including cleaning, security, maintenance, repairs, insurance, real estate taxes, and management fees. CAM is typically passed through to retail tenants either on a pro-rata share basis (tenant pays a percentage of total building CAM based on their square footage) or as a fixed additional rent stated in dollars per square foot per year. NYC retail CAM in 2026 typically runs $15 to $50 per square foot per year in Manhattan buildings, with significant variation by building type, age, and management. The negotiable items: caps on annual CAM increases (commonly negotiated to 4 to 6 percent year over year), the definition of what's included in CAM (excluding capital improvements, landlord's affiliated party costs, and the costs of major repairs), and the right to audit CAM expenses. Real estate taxes are often broken out from CAM as a separate pass-through and should be capped or based on a base year. Station CRM has a NNN lease analyzer that breaks down CAM and pass-through costs for any deal.
What CAM actually covers
CAM is the landlord's way of recovering the costs of operating the building from the tenants. The category typically includes:
Building cleaning and maintenance of shared areas (lobbies, hallways, exterior walkways).
Security (cameras, doormen, building staff).
Snow removal, landscaping, and exterior maintenance.
Repairs to common building systems.
Building insurance, including liability and property.
Real estate taxes (often broken out separately as "RE tax" or "taxes" rather than included in CAM).
Building management fees (the landlord's cost of managing the property).
Utilities for common areas.
Some leases include capital improvements in CAM, which is a major negotiating point. The tenant should push to exclude capital improvements or to amortize them over their useful life rather than pass through the full cost in the year incurred.
How CAM is structured
A few different structures show up in NYC retail leases:
Pro-rata share. The tenant pays a percentage of total building CAM equal to their share of the building's rentable square footage. This is the most common structure in mixed-use buildings and multi-tenant retail properties. The tenant's share is typically defined as their square footage divided by the building's total rentable square footage, with the right to adjust if the building's square footage changes.
Fixed CAM (dollar per square foot per year). The tenant pays a fixed dollar amount per square foot per year, often with annual escalations. This is simpler administratively but less common in NYC retail because landlords prefer the pass-through structure.
Triple net (NNN). The tenant pays a base rent plus pro-rata share of CAM, real estate taxes, and insurance. This is the standard structure for single-tenant net leases. See the NNN lease analyzer for the breakdown.
Modified gross. The base rent includes a stated base year of operating expenses. The tenant pays escalations only for amounts over the base year. This structure protects the tenant from the full pass-through but caps the protection at the base year amount.
Each structure has different implications for the tenant's total occupancy cost and the negotiating room on different line items.
What CAM costs in NYC retail in 2026
Approximate ranges by building type:
Class A Manhattan office building ground floor retail: $25 to $50 per square foot per year. The high end on prime corridors with active building staff and amenities.
Manhattan mixed-use building, residential above: $15 to $35 per square foot per year. Lower than Class A office because the building services are simpler.
Manhattan retail-only or small commercial building: $10 to $25 per square foot per year. The lowest CAM structures because the operating expenses are simplest.
Brooklyn and outer borough retail: $5 to $20 per square foot per year. Significant variation.
Real estate taxes are often the largest single line item in the pass-through stack, sometimes exceeding the CAM total itself. Tax pass-throughs in NYC can be substantial, and the tenant should understand how the lease defines the base year and the escalation methodology.
The clauses worth fighting on
Specific lease language that matters for the tenant:
Cap on annual increases. Without a cap, CAM can rise materially year over year, and the tenant has no protection against landlord cost discipline. A negotiated cap of 4 to 6 percent year over year is common in NYC retail leases. Lower caps (3 percent) are achievable for stronger tenants.
Exclusions from CAM. Specific categories that should be excluded:
- Capital improvements (or amortize over useful life)
- Costs paid by other tenants or recovered through insurance
- Landlord's marketing and leasing costs
- Costs of work done for specific tenants
- Affiliated party costs above market rates
- Costs related to violations or fines from the landlord's negligence
- Capital reserves for future repairs
Base year for real estate taxes. If taxes are passed through as escalations over a base year, the base year should be the first full year of the lease. The tenant pays only escalations above that year.
Audit right. The tenant should have the right to audit the landlord's CAM books at the tenant's expense, with the landlord required to reimburse the audit cost if material discrepancies are found (often defined as 3 to 5 percent overstatement). Without an audit right, the tenant has no way to verify what they're being charged.
CAM reconciliation timing. The lease should require the landlord to provide CAM reconciliations within a defined period (often 90 to 120 days after year end), with the tenant's right to dispute defined.
Definition of building square footage. If pro-rata share is calculated as the tenant's square footage divided by the building's rentable square footage, the lease should define both clearly. Some leases allow the landlord to adjust the rentable square footage in ways that increase the tenant's share unfavorably.
What landlords push for
The landlord side typically wants:
The broadest possible definition of CAM, including capital improvements and a wide range of cost categories.
No cap on annual increases, or a high cap.
No audit right, or an audit right with significant restrictions.
The right to estimate CAM in advance and collect monthly with reconciliation at year end.
The ability to allocate certain costs disproportionately to specific tenants (for example, allocating common area cleaning costs to ground floor retail at a higher rate than upper floor office).
Each of these is negotiable. Strong tenants get more. Smaller tenants get less. The broker's job is to understand which items the specific landlord will move on and prioritize accordingly.
How brokers should approach the negotiation
A few practical approaches:
Get the landlord's CAM history before signing. Ask for the last two or three years of actual CAM reconciliations from the building. This tells you what the tenant is actually going to pay, not just what the asking number is. A landlord who refuses to share this is a yellow flag.
Negotiate caps as a package. The cap on annual increases is often easier to negotiate when paired with concessions elsewhere. A landlord who won't move on rent might move on the CAM cap.
Push on the exclusions list. The list of items excluded from CAM is often less heavily defended than the cap or the audit right. A few specific exclusions can save the tenant meaningful money over the lease term.
Get the audit right. Audit rights are commonly given because the landlord doesn't expect the tenant to use them. They become valuable when the tenant has a reason to investigate. Negotiate it in.
Model the all-in occupancy cost, not just rent. A space at $300 per square foot asking with $35 per square foot CAM is more expensive than a space at $320 with $20 CAM, all else equal. The CAM number affects total occupancy cost as much as the base rent does over a 10-year lease.
Where CAM has changed in 2026
A few things worth noting about how CAM is moving in NYC retail:
CAM dollar amounts have increased meaningfully in the past few years, driven by inflation in building services, insurance costs, and security. Landlords are passing more through because their operating costs are higher. Tenants should expect the asking CAM number to be higher than it was three years ago.
Some landlords are restructuring leases toward fully-grossed-up rents (where the base rent includes operating costs and there's no separate pass-through). This is more common in single-tenant retail and less common in multi-tenant buildings. It simplifies the negotiation but typically results in a higher base rent.
Real estate tax escalations have become more contentious because of broader NYC property tax dynamics. The base year structure is worth more attention than it used to be.
The bigger picture
CAM is one of those parts of a lease that tenants don't pay enough attention to during negotiation and then complain about for the next ten years. The broker who works through the CAM structure carefully at the LOI and lease stage saves the tenant significant money over the term, and earns the relationship that produces repeat business.
