If you own or manage industrial property in West Michigan, you have probably faced a version of this moment. A major expense arrives, maybe a full roof replacement, a parking lot overhaul, or a significant HVAC system upgrade, and suddenly you and your tenant are reading the same lease and reaching completely different conclusions about who should pay for it. These disputes can feel deeply frustrating, especially when you have invested significantly in a property and believe the lease clearly supports your position. Often, the challenge is not bad faith on either side. It is genuinely ambiguous lease language that creates room for disagreement.
We work with landlords and property managers throughout Kent County, Ottawa County, and the surrounding West Michigan region, and these conversations come up regularly. Commercial real estate law in Michigan generally treats industrial leases as contracts between sophisticated parties, which means the written terms of your agreement carry enormous weight if disputes arise. Understanding what your lease says, and what it should say, is foundational to protecting your investment and your operating margins.

The Tension at the Heart of Every NNN Lease
Triple net leases are widely used in West Michigan’s industrial market. In a standard NNN structure, tenants pay base rent plus their proportionate share of property taxes, insurance, and common area maintenance (CAM) costs. For landlords, this structure offers more predictable net income and reduces exposure to fluctuating operating expenses.
The tension arises between two categories of expense: routine maintenance and repairs on one side, and capital improvements on the other. Routine maintenance, things like snow removal, landscaping, parking lot crack-sealing, and minor building repairs, typically flows through as a CAM charge that tenants share proportionately. Capital improvements, meaning work that adds significant value to the property or extends its useful life beyond the current lease term, are generally considered the landlord’s responsibility unless the lease addresses them differently.
In practice, that line can be difficult to draw. A roof that has been patched repeatedly over a long tenancy eventually reaches a point where replacement becomes necessary. Is that replacement a repair or a capital improvement? A landlord may reasonably view it as a maintenance issue that accumulated over time. A tenant may view it as a capital expenditure the landlord should absorb. Michigan law generally looks to the lease language to resolve that question, not to some external standard of what seems fair.
Why Lease Language Makes All the Difference
This is where many landlords find themselves in a difficult position, not because their position is wrong, but because the lease does not say what they thought it said. Vague phrases like “repairs and replacements” or “maintenance of building systems” can create genuine uncertainty about whether a major expenditure qualifies as a pass-through CAM expense or a landlord obligation. And when lease language is genuinely ambiguous, courts in Michigan tend to interpret that ambiguity against the party that drafted the agreement if intent cannot be determined through conventional interpretation rules. In most industrial NNN leases, that is the landlord.
Well-drafted leases address this directly. They define CAM expenses with specificity, distinguish between routine maintenance that flows through to tenants and capital improvements that do not, and establish a clear process for handling the gray areas that inevitably arise over the life of a long-term industrial tenancy. Our commercial lease attorneys help you get this language right at the outset, as it is far less costly than resolving a dispute after the fact.
The Amortization Clause: Protecting Landlord Recovery
For landlords, one of the most valuable tools in an NNN lease is a well-crafted amortization clause. When a significant capital improvement cannot reasonably be characterized as routine maintenance, amortization allows the landlord to recover a proportionate share of that cost over the useful life of the improvement, rather than either absorbing the full cost or attempting to pass it through in a single year in a way the lease may not clearly support.
Over the life of a multi-tenant industrial property, major capital expenditures on roofs, HVAC systems, parking surfaces, and building infrastructure can represent significant costs. Landlords who have not built amortization recovery into their leases absorb those costs entirely, which affects net operating income, property valuation, and the ability to refinance or sell the asset at a favorable price.
A strong amortization clause typically specifies the calculation method (straight-line amortization is standard industry practice), defines which improvements qualify for amortized recovery versus which are fully excluded from CAM, addresses whether an interest component may be included in the amortized cost, and establishes the applicable useful life standard. Some landlords reference IRS depreciation guidelines as an objective benchmark for useful life determinations, which can help defend the amortization schedule if a tenant disputes it.
Building a CAM Structure That Holds Up
The amortization clause is one part of a broader drafting strategy. Landlords managing industrial properties across West Michigan should also pay careful attention to several related provisions that affect both CAM dispute risk and overall cost recovery.
Expense definitions need to be specific. The lease should clearly identify what qualifies as a CAM expense, what is excluded, and what falls into the amortized capital improvement category. Leaving this to interpretation creates the conditions for exactly the kind of dispute that is expensive and time-consuming to resolve.
Reconciliation timelines matter as well. NNN leases generally require the landlord to deliver an annual CAM reconciliation statement comparing estimated payments collected during the year against actual expenses incurred. Landlords who deliver these statements on time, with adequate supporting documentation, are in a much stronger position if a tenant challenges a charge. Landlords who are late or whose reconciliations lack documentation face real collection risk.
In multi-tenant buildings, the gross-up provision protects landlords when vacancy occurs. If one tenant vacates, the remaining tenants should not automatically bear a larger share of variable operating costs simply because the denominator changed. A properly drafted gross-up clause allows the landlord to normalize variable CAM expenses to reflect full occupancy, which protects cost recovery and keeps the allocation equitable among paying tenants.
Audit rights provisions, while often associated with tenant protection, can be structured in ways that benefit landlords too. A thoughtfully drafted audit clause sets reasonable notice periods, limits the lookback window, specifies the format of supporting records, and establishes clear consequences if an audit reveals an underpayment. Landlords who shape the audit process through careful drafting are better positioned than those operating under vague or broadly tenant-favorable audit language.
When Disputes Reach Kent County Courts
CAM disputes in West Michigan industrial leases that cannot be resolved between the parties often end up in Kent County Circuit Court, where Michigan courts apply contract law principles to commercial lease agreements. The written terms of the lease govern, and courts generally enforce what the parties agreed to rather than what either party now believes would have been fairer.
Landlords with well-documented CAM reconciliations, clear lease language, and a defined amortization process are in a meaningfully stronger position than those relying on form leases or ambiguous maintenance provisions. The investment in careful drafting at the front end of a tenancy pays dividends throughout the lease term and especially when a dispute arises.

If you manage industrial space in the Grand Rapids area and your leases are several years old, it may be worth having them reviewed with fresh eyes. Buildings age, major systems approach end of life, and lease language that seemed adequate when the building was new can create real exposure as capital expenditures become more likely. Understanding what your current leases say, and what they do not say, is a reasonable first step toward protecting your investment.
