Wisconsin Commercial Lease Disclosures

Wisconsin's extensive ATCP 134 disclosure framework—covering habitability defects, utility charges, and nonstandard provisions—applies only to residential rentals. Commercial landlords in Wisconsin face far fewer mandatory disclosure requirements, operating under a caveat emptor (buyer beware) framework.

Minimal State-Mandated Disclosures

Wisconsin commercial landlords are generally not required by state statute to provide pre-lease disclosures regarding:

• Building code violations.
• Utility charges or billing arrangements.
• The condition of HVAC, plumbing, or electrical systems.
• Prior flooding or environmental events.

The commercial tenant is expected to conduct their own due diligence—hiring inspectors, reviewing zoning records, and evaluating the condition of the property before signing a lease.

Environmental Considerations

While not a formal "disclosure" mandate like ATCP 134, commercial landlords should be aware of environmental liability under both state and federal law:

Phase I Environmental Site Assessments (ESA)

Prospective commercial tenants (especially for industrial or former gas station sites) should request a Phase I ESA before signing. While not legally required of the landlord, failing to disclose known contamination when directly asked may constitute fraud.

Wisconsin DNR Brownfield Programs

If the property has a history of environmental contamination, the Wisconsin Department of Natural Resources (DNR) maintains records that can be reviewed. Landlords marketing properties with environmental issues should proactively disclose to avoid costly post-lease litigation.

Lead-Based Paint Exemption

The federal lead-based paint disclosure requirement (for properties built before 1978) applies only to residential properties. 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, the most important practical disclosure in any commercial lease is the property's zoning classification and whether the tenant's intended use is permitted.

• Landlords should clearly state the property's zoning in the lease.
• The lease should specify that it is the tenant's responsibility to obtain all necessary zoning variances, conditional use permits, and occupancy certificates.
• Leasing a property to a tenant whose business violates local zoning can expose both parties to enforcement actions.

ADA Compliance Under the Americans with Disabilities Act (ADA), both the landlord and tenant can be held responsible for ensuring a commercial property is accessible. While this is not a "disclosure" per se, prudent landlords should disclose known ADA deficiencies so the lease can apportion the financial responsibility for required upgrades.

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.
