Required Commercial Disclosures

Methamphetamine Manufacturing Disclosure

Under SDCL §43-32-30, commercial landlords with actual knowledge that methamphetamine was previously manufactured on the premises must disclose this information to prospective tenants before the lease is signed.

Key Points

• Applies to all property types including commercial
• Required only if the landlord has actual knowledge — no duty to investigate
• For multi-unit properties, applies only to the specific unit where manufacturing occurred
• Should be disclosed in writing and documented

Environmental Contamination

Federal Requirements

Under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commercial property owners may be liable for contamination on their properties. While not a direct disclosure requirement, prudent landlords should:

• Disclose any known environmental contamination
• Provide copies of Phase I or Phase II environmental assessments
• Inform tenants of any ongoing remediation activities
• Note proximity to known contaminated sites

State Environmental Requirements

South Dakota may require disclosure of:

• Hazardous materials — Known presence of asbestos, PCBs, or other regulated substances
• Underground storage tanks — Current or former tanks on the property
• Soil or groundwater contamination — Any known contamination issues

Material Property Defects

While South Dakota does not have a specific commercial property condition disclosure statute, the duty of good faith and fair dealing requires landlords to disclose:

• Structural deficiencies — Known issues with the building's structural integrity
• Roof or foundation problems — Current leaks or structural concerns
• System failures — HVAC, electrical, or plumbing systems that are not fully operational
• Code violations — Any outstanding building code or fire code violations
• Pending litigation — Lawsuits that could affect the tenant's use of the property
• Utility issues — Known problems with water, sewer, or electrical service

Zoning and Use Restrictions

While not strictly required by statute, commercial landlords should disclose:

• Current zoning classification of the property
• Permitted uses under the zoning code
• Any variances or special permits associated with the property
• Planned zoning changes that could affect the tenant's business
• Deed restrictions or covenants that limit property use
• HOA or business association rules that may apply

Failure to disclose zoning restrictions can lead to disputes if the tenant's intended use is not permitted.

ADA Compliance

For commercial properties, landlords should disclose:

• Current ADA compliance status of the property
• Any known accessibility barriers
• Planned or required ADA improvements
• The tenant's responsibilities for ADA compliance within their leased space

Best Practices for Commercial Landlords

1. Disclose proactively — Voluntarily disclosing known issues reduces legal risk
2. Get everything in writing — Document all disclosures in the lease or a separate disclosure form
3. Obtain tenant signatures — Have the tenant acknowledge receipt of each disclosure
4. Conduct due diligence — Perform environmental and structural assessments before leasing
5. Update disclosures — Provide updated information if conditions change during the tenancy
6. Consult professionals — Work with environmental consultants, attorneys, and inspectors as needed
7. Keep permanent records — Store all disclosure documents for the life of the property
