Wisconsin Commercial Lease Disclosures

Since Wisconsin's admission to the Union on May 29, 1848, its property laws have evolved to distinguish sharply between residential and commercial protections. While the extensive ATCP 134 disclosure framework applies only to residential rentals, commercial landlords must still navigate specific statutory mandates under Chapter 704 unless expressly waived in the lease.

Mandatory Statutory Disclosures

While Wisconsin is largely a caveat emptor state for commercial property, specific statutory requirements apply:

1. Health and Safety Threats

Regarding health and safety threats, Wis. Stat. § 704.07(1) explicitly states that the section, which outlines landlord and tenant duties concerning repairs and untenantability, does not apply to a rental agreement for a nonresidential tenancy, except as provided in sub. (2)(a)3. Consequently, there is no specific statutory mandate under Wis. Stat. § 704.07 requiring commercial landlords to disclose building or housing code violations posing a significant threat to health or safety.

[!IMPORTANT] For commercial leases, parties generally have the freedom to waive or modify maintenance and disclosure duties through a written lease agreement. In the absence of specific lease provisions, the statutory repair and maintenance obligations found in Chapter 704 do not apply to nonresidential tenancies.

2. Broker Disclosure to Customers

If a real estate broker or agent is involved in the transaction, Wis. Stat. § 452.135 requires them to provide a written "Disclosure to Customers" form. This document outlines the duties the broker owes to both the landlord and the prospective tenant, ensuring transparency in representation.

Environmental and Latent Defects

Wisconsin commercial landlords are generally not required to provide the standard "Real Estate Condition Report" (required for residential sales under Ch. 709). However, failure to disclose known latent defects (hidden issues that a reasonable inspection wouldn't reveal) can still lead to claims of fraudulent misrepresentation in Wisconsin Circuit Courts.

Hazardous Substance Spills

Under Wis. Stat. § 292.11, individuals who "possess or control" a hazardous substance that is discharged must notify the Department of Natural Resources (DNR). Commercial landlords should disclose any history of such discharges to avoid future liability under the state's "Spill Law."

Federal Lead-Based Paint Exemption

The federal lead-based paint disclosure requirement (42 U.S.C. § 4852d) applies only to residential properties (target housing). Commercial landlords leasing office, retail, or industrial space are exempt from providing lead paint disclosures, even if the building was constructed before 1978.

Zoning and Permitted Use

While not a statutory disclosure mandate for the landlord, the zoning classification is the most critical due diligence item:

• The lease should specify that it is the tenant's responsibility to verify that their intended business use is permitted under local ordinances.
• Landlords should clearly state the current zoning but avoid guaranteeing that a specific business permit (like a liquor license or daycare permit) will be granted.

ADA Compliance

The Americans with Disabilities Act (ADA) is a federal civil rights law. While not a "disclosure," Wisconsin commercial landlords should disclose known accessibility barriers. Prudent leases clearly apportion the financial responsibility for ADA upgrades between the parties to prevent litigation.

How Landager Helps

Landager allows commercial landlords to attach due diligence documents—environmental reports, zoning letters, and ADA assessments—directly to the lease file, creating a transparent record that protects both parties and satisfies the "fair dealing" expectations of Wisconsin courts.
