CAM Benchmarks by Property Type: 2026 Operating Expense Ranges
CAM rates vary significantly by property type, location, and building vintage. This guide provides operating expense ranges for office, retail, and industrial properties, explains what drives variation within each category, and shows how to use benchmarks as a self-audit tool — not a budget ceiling.

Quick Answer
CAM rates vary significantly by property type, location, and age of building. Office properties typically carry the highest CAM (driven by HVAC, security, engineering staff, and amenities), industrial the lowest. Class A office often runs $4–8/SF/year in CAM alone; a warehouse might run $1–3/SF. These figures are illustrative ranges from institutional portfolios — individual properties vary significantly based on building age, market, and lease structure.
2026 CAM Benchmark Ranges by Property Type
| Property Type | Typical CAM Range | Total Opex Range | Key Cost Drivers |
|---|---|---|---|
| Class A Office | $4–8/SF | $8–15/SF | HVAC, engineering staff, security, amenities, high-finish lobbies |
| Class B / Suburban Office | $3–6/SF | $6–10/SF | HVAC maintenance, janitorial, parking lot, landscaping |
| Retail – Neighborhood / Strip | $3–6/SF | Varies (often included in NNN base) | Parking lot maintenance, landscaping, exterior lighting, trash |
| Retail – Power Center / Lifestyle | $2–5/SF | Varies by anchor structure | Shared parking, outdoor common area, management fee, insurance |
| Industrial – Warehouse / Distribution | $1–3/SF | $1.50–4/SF | Roof, dock doors, truck court, exterior lighting, landscaping |
| Industrial – Flex | $2–4/SF | $3–6/SF | Office-finish common areas, HVAC, janitorial, restrooms |
Office: What Drives the Wide Range
The $4–8/SF CAM range for Class A office reflects a genuinely wide spread in operating profiles. The primary drivers of variation:
- Building vintage: A 1985-vintage office tower with original HVAC equipment will spend significantly more on maintenance and energy than a 2015 building with a high-efficiency system. Older buildings often carry HVAC operating costs 40–70% above newer equivalents.
- Amenity level: Buildings with conference centers, fitness facilities, food and beverage, and concierge services carry materially higher janitorial, utility, and staffing costs than plain vanilla office.
- Market labor costs: Janitorial and security are labor-intensive. In San Francisco or New York, wages for these roles run 50–80% above the national average, pushing CAM above the range floor even in buildings that would otherwise be unremarkable.
Retail: Why CAM Varies Between Center Types
Retail CAM is heavily influenced by the parking field. A neighborhood strip center may spend $1.00–$1.50/SF on parking lot maintenance, striping, sweeping, and snow removal alone. A lifestyle center with landscaped outdoor commons, fountains, and event infrastructure carries substantial ongoing maintenance costs that a power center with asphalt and minimal landscaping does not.
The management fee structure in retail leases also creates variation. An 8% management fee applied to a $4/SF operating expense base adds $0.32/SF to the recoverable pool. Some retail leases cap the management fee at a fixed dollar amount; others apply it to the gross recoverable expense pool including insurance and taxes. The management fee treatment is one of the most frequently audited line items in retail CAM.
Industrial: The Lean Profile and Its Exceptions
Pure warehouse and distribution CAM is lean because the expense categories are few: roof maintenance and replacement (often amortized), dock door and leveler maintenance, truck court and parking pavement, exterior lighting, and landscaping. There is no HVAC in the warehouse bay (or minimal heating only), no janitorial beyond office areas, and no amenity infrastructure.
Flex industrial breaks from that pattern because it includes office buildouts with full HVAC, finished common areas, and restrooms — all of which require janitorial, HVAC maintenance, and periodic capital improvement. A flex portfolio that is benchmarked against pure warehouse standards will always look expensive on paper.
How to Use These Benchmarks for Self-Auditing
The most productive use of CAM benchmarks is outlier identification — not budget-setting. If your Class B suburban office building is running $9/SF in total operating expenses when the range is $6–10/SF, that is within bounds. If it is running $14/SF, that warrants investigation. The question is not whether the number is above the range — it may have a legitimate explanation — but whether you can explain the variance with specific facts.
For internal portfolio benchmarking, normalize by building age cohort (pre-2000, 2000–2015, 2015+) and by submarket before comparing across properties. A portfolio that spans markets from Phoenix to Manhattan should never use a single national benchmark as its performance target — the structural cost differences are too large.
Portfolio tip: Track CAM per SF by property over three or more years. A property that is within benchmark range but growing 8% per year while comparable properties are growing 3% is more concerning than one that sits slightly above the range with a stable year-over-year trend.
What Can Go Wrong
Using retail benchmarks for mixed-use properties
A mixed-use building with retail on the ground floor and office above has a fundamentally different expense profile than a pure retail center. The office portion requires HVAC maintenance, elevator service, and restroom janitorial that are not typical retail expenses. Applying retail benchmarks to the entire building understates legitimate CAM in the office component — and may cause a landlord to underbill tenants or accept incorrect audit findings.
Using national benchmarks for high-cost markets without adjustment
A property manager who compares a San Francisco Class A office building against national BOMA averages will conclude the building is dramatically over-budget when it is actually performing in line with the local market. San Francisco janitorial rates, security costs, and elevator maintenance contracts are 50–80% above national averages. The right benchmark is the local market — not a national average that includes Dallas and Kansas City.
Treating the benchmark as a cap rather than a reference point
A tenant audit firm that claims your $9/SF office CAM is "above benchmark" and therefore overbilled has misused the data. Benchmarks describe observed distributions — they do not establish what is contractually recoverable. A lease that allows recovery of all operating expenses does not become invalid because those expenses exceed a national average. Landlords should never accept audit settlements based solely on benchmark comparisons without a lease-specific analysis.
Frequently Asked Questions
What is a typical CAM charge for an office building in 2026?
Class A office buildings typically carry a CAM component of $4–8 per rentable SF per year, with total operating expenses ranging from $8–15/SF. Class B and suburban office runs lower at $3–6/SF for CAM. These ranges reflect institutional portfolios in major U.S. markets; older buildings or properties in high-cost markets will often exceed these ranges.
Are CAM benchmarks the same as typical outcomes?
No. Benchmarks are ranges drawn from observed portfolios and should be treated as reference points, not performance targets or caps. A $5/SF CAM rate at a 1975-vintage building with aging HVAC infrastructure is not comparable to a $5/SF rate at a 2018 Class A property. Benchmarks are most useful for flagging outliers that warrant investigation — not for making lease or budget decisions on their own.
Why is industrial CAM so much lower than office CAM?
Industrial properties have far fewer amenity-driven expense categories. Office buildings carry significant costs for lobbies, elevators, restrooms, HVAC in occupied suites, and high-finish common areas. A warehouse has a concrete pad, a roof, dock doors, and a parking lot. The expense base is structurally smaller. Flex industrial is slightly higher because it includes office-finish common areas and restrooms.
How should I adjust national benchmarks for my market?
Apply a cost-of-living adjustment for labor (janitorial, security) and a construction-cost index for maintenance and repairs. Markets like San Francisco, New York, Boston, and Seattle carry labor costs 40–80% above national averages, which flows directly into janitorial, security, and engineering expenses. National benchmarks should be treated as a floor in high-cost markets, not a ceiling.
