Wisconsin Commercial Maintenance Obligations and § 704.07 Defaults

Unlike many states where commercial maintenance is purely a contract matter, Wisconsin's Wis. Stat. § 704.07 provides default maintenance rules that apply to commercial leases unless the parties explicitly agree otherwise. Since Wisconsin's statehood on May 29, 1848, its statutory framework has evolved to create a baseline even when the lease is silent on maintenance.

Default Rules Under § 704.07

In the absence of a contrary provision in a written lease signed by both parties, maintenance obligations for commercial properties in Wisconsin are governed by Wis. Stat. § 704.07:

Landlord's Default Obligations

• Structural repairs: Make all necessary structural repairs (§ 704.07(2)(a)3).
• Control-based repairs: Keep in a reasonable state of repair portions of the premises over which the landlord maintains control (§ 704.07(2)(a)1).
• Service equipment: Keep in a reasonable state of repair all equipment under the landlord's control necessary to supply services that the landlord has expressly or impliedly agreed to furnish, such as heat, water, elevator, or air conditioning (§ 704.07(2)(a)2).
• Furnished equipment: Repair or replace any plumbing, electrical wiring, machinery, or equipment furnished with the premises and no longer in reasonable working condition, except as provided in the tenant's minor repair exception (§ 704.07(2)(a)4).

Tenant's Default Obligations

• Negligence and Misuse: Repair damage (including infestations of insects or other pests) caused by the acts, inaction, negligence, or improper use of the premises by the tenant (§ 704.07(3)(a)).
• Minor Repairs to Equipment: Keep plumbing, electrical wiring, machinery, and equipment furnished with the premises in reasonable working order if repair can be made at a cost which is minor in relation to the rent (§ 704.07(3)(b)).
• Sanitation: Keep the premises in a clean and sanitary condition (§ 704.07(3)(b)).

How NNN Leases Override the Defaults

In a Triple Net (NNN) lease—the most common structure for freestanding retail, warehouse, and industrial properties in Wisconsin—the lease contractually shifts nearly all maintenance obligations to the tenant, overriding the § 704.07 defaults.

Under a typical NNN lease, the tenant is responsible for:

• Roof repairs and replacement.
• Parking lot repaving and maintenance.
• HVAC system servicing and replacement.
• All plumbing, electrical, and fire suppression systems.
• Snow removal and landscaping.
• Building insurance and property tax payments.

The landlord's only obligation may be limited to major structural issues (foundation, load-bearing walls) or may be eliminated entirely in an "absolute net" lease.

Gross Lease Maintenance

In a gross or full-service lease (common for multi-tenant office buildings), the landlord retains responsibility for most maintenance and passes the cost to tenants through higher base rent or operating expense escalations.

Typical landlord responsibilities in a gross lease include:

• All structural and exterior maintenance.
• HVAC, elevator, and mechanical systems.
• Common area cleaning and landscaping.
• Roof and parking lot maintenance.

ADA Compliance

Both the landlord and tenant can be liable for ensuring the property meets Americans with Disabilities Act (ADA) standards. The lease should clearly allocate:

• Who pays for required ADA upgrades (e.g., ramps, accessible restrooms).
• Whether structural ADA modifications fall to the landlord while interior modifications fall to the tenant.

Capital Expenditures vs. Routine Repairs

A common source of dispute is distinguishing between a capital expenditure (e.g., replacing an entire HVAC system) and a routine repair (e.g., fixing a compressor). Well-drafted leases define:

• A dollar threshold separating capital from routine expenses.
• Whether capital expenditures are amortized over the useful life of the improvement and billed to the tenant annually.
