How Do I Avoid the 'Controllable vs Uncontrollable' CAM Trap?

Direct Answer

You avoid the trap by demanding a controllable-expense cap of 3% to 5% per year, compounded on a cumulative base, and then fighting just as hard over which expenses count as "uncontrollable" — because that second word is where landlords hide the money. A standard CAM cap sounds protective: "annual increases on controllable expenses limited to 5%." The catch is that landlords carve out a huge uncontrollable bucket — taxes, insurance, utilities, snow removal, and security — that faces no cap at all and can rise 10%, 20%, even 40% in a bad year.

On a space paying $8 per square foot in CAM, an uncapped uncontrollable bucket that is 60% of the total means most of your CAM is unprotected even though you "have a cap." The money moves: (1) get the cap set at 3% to 4%, not 5%; (2) insist it is cumulative/compounding (unused room carries forward) rather than year-over-year (which lets a landlord bank big jumps); (3) shrink the uncontrollable bucket to only real taxes, insurance, and utilities, and push management fees, security, landscaping, and snow removal back into the capped controllable side; and (4) cap the management fee at 3% to 5% of gross revenue as a hard number.

The single biggest screw-up: accepting the landlord's definition of "uncontrollable" without editing the list. The cap is only as good as how small you make the bucket it does not cover.

What "Controllable vs Uncontrollable" Actually Means

In a triple-net (NNN) lease, you reimburse your pro-rata share of CAM (Common Area Maintenance) on top of base rent. To make caps palatable, the market splits CAM into two buckets:

• Controllable expenses — things the landlord can manage: landscaping, parking-lot maintenance, management fees, administrative fees, common-area cleaning, security, and general repairs. These are supposed to be the *capped* bucket.
• Uncontrollable expenses — things the landlord supposedly cannot control: real estate taxes, building insurance, utilities, and (often) snow removal. These face no cap because, the argument goes, the landlord cannot stop a tax hike or a hard winter.

The logic is fine in principle. The abuse is in execution: landlords stuff the uncontrollable bucket with items that are clearly controllable so they escape the cap. The fight is not whether to have a cap — it is drawing the line between the two buckets so the uncapped side stays small.

A cap that covers only 30% to 40% of your CAM is mostly decorative. A cap that covers 70%+ of your CAM, with a tight uncontrollable list, is real protection.

The Cap Structure — Get Compounding And A Low Number

How the cap is *structured* matters as much as the percentage:

• Cumulative (compounding) cap — demand this. Unused cap room carries forward. If the cap is 4% and expenses rise only 1% in year one, you carry 3% forward, so year two can rise up to 7% before you are protected. This averages out bumpy years in your favor.
• Year-over-year (non-cumulative) cap — refuse this. Each year stands alone at the cap. Landlords love it because they can hold costs flat in light years, then spend heavily and still bill you the full cap every year after. It also lets them bank increases by timing spending.
• The percentage: aim for 3% to 4%. Landlords open at 5%, sometimes higher. With inflation history in mind, 5% compounding is acceptable; 3% to 4% compounding is strong. Below 3% is rare but worth asking on a competitive deal.
• Base year matters. The cap applies to growth above a base-year amount. Make sure the base year is a normal, fully-occupied year, not an artificially low one that inflates every future increase, and not an artificially high "stuffed" base that you then pay forever.

Shrink The Uncontrollable Bucket — Line By Line

This is the part tenants skip and landlords count on. Go through the CAM definition line by line and reclassify:

• Management fees → controllable. A management fee is the most controllable expense there is — the landlord chooses the manager and the rate. It belongs in the capped bucket, and it should be capped as a hard number at 3% to 5% of gross rental revenue, not "market rate."
• Administrative fees → controllable or eliminated. A separate 10% to 15% admin fee layered on top of the management fee is often double-dipping. Push to fold it into the management fee or strike it.
• Security → controllable. The landlord decides how much security to buy. It is not a tax. Cap it.
• Landscaping and snow removal → controllable. Landlords classify snow as "uncontrollable" because winters vary, but the *contract rate and scope* are entirely the landlord's choice. At minimum, cap snow removal at a reasonable per-event or seasonal figure, or push it into the controllable bucket with a generous cap.
• Utilities → mostly uncontrollable, but watch capital tie-ins. Common-area utility *rates* are genuinely uncontrollable, but a landlord cannot dump a lighting-retrofit capital project into "utilities."
• Taxes and insurance → genuinely uncontrollable, but verify. These belong in the uncapped bucket, but you still get to audit them — make sure tax bills reflect actual assessments and insurance is at market rates, not a captive affiliate's inflated premium. Also negotiate the right to benefit from any tax appeal/protest the landlord wins.

The goal: an uncontrollable bucket that is only taxes, insurance, and genuine pass-through utilities — ideally 40% or less of total CAM — leaving the majority under your cap.

The Math — Why The Bucket Split Beats The Cap Number

Run two scenarios on a 10,000-square-foot space with $8 per square foot in CAM ($80,000 total) and a 5% cap.

Scenario A — landlord's split (bad): Uncontrollable bucket is 65% ($52,000) and uncapped. Controllable is 35% ($28,000) and capped at 5%. A bad year hits: taxes and insurance jump 18%, snow removal (parked in uncontrollable) jumps 30%.

Your uncontrollable bill rises about $10,000 with no cap; your controllable rises $1,400. Total CAM increase: ~$11,400 (14%) — despite "having a cap."

Scenario B — your split (good): You pulled management fees, security, landscaping, and snow into the controllable side. Now uncontrollable is only 40% ($32,000 — taxes, insurance, utilities) and controllable is 60% ($48,000), capped at 4% cumulative. Same bad year: uncontrollable rises about $5,800; controllable is capped to about $1,920.

Total increase: ~$7,720 (9.6%) — and the controllable side is protected forever.

Same 5% cap percentage in A; a tighter 4% in B — but the bucket split did most of the work. The lesson: the line between the buckets is worth more than a point or two on the cap.

Negotiating Leverage And Watch-Outs

Your leverage is before signing, bundled with your other CAM asks (audit right, capital-expense amortization, exclusions list). Practical watch-outs:

• "Uncontrollable" is a negotiable definition, not a law of nature. Edit the list. Landlords expect pushback from sophisticated tenants and concede more than you think.
• Beware "gross-up to 95%." Fine in concept (it makes vacant space pay its share), but confirm it applies to variable costs only, not fixed.
• Cap capital expenses separately. A new roof or HVAC should be amortized over its useful life (15 to 25 years) and only the annual amortized slice billed — never a lump sum, and never hidden in "uncontrollable repairs."
• Get the cap in writing with a worked example. Ambiguous cap language ("increases limited to a reasonable amount") is worthless. Include a numeric definition and, ideally, a sample calculation in the lease.
• Tie the cap to a real audit right so you can verify the landlord is honoring the bucket split each reconciliation.

FAQ

What's a fair CAM cap percentage? Aim for 3% to 4% per year, compounding/cumulative. Landlords open at 5%; a 5% compounding cap is acceptable, but the percentage matters less than two other things: whether the cap is cumulative (unused room carries forward) versus year-over-year, and how small you make the uncontrollable bucket the cap does not cover.

Why is the "uncontrollable" bucket such a trap? Because it faces no cap, and landlords stuff it with expenses that are actually controllable — management fees, security, landscaping, and snow removal — so most of your CAM escapes the cap. A cap covering only 30% to 40% of CAM is decorative.

Reclassify those items into the controllable bucket so your cap covers 70% or more of total CAM.

Should management fees be controllable or uncontrollable? Controllable, always — the landlord chooses the manager and sets the rate, so nothing is more controllable. Beyond putting it in the capped bucket, cap the management fee itself at a hard 3% to 5% of gross rental revenue, and strike any separate 10% to 15% admin fee layered on top, which is usually double-dipping.

What's the difference between a cumulative and year-over-year cap? A cumulative (compounding) cap carries unused room forward, smoothing bumpy years in your favor. A year-over-year cap resets each year, letting the landlord hold costs flat in light years and then bill the full cap every year after — effectively banking increases.

Always negotiate the cumulative version.
