Official Law Citation: Commercial real estate disclosures are largely regulated by the negotiation process and common law principles rather than specific, mandatory consumer disclosures in Delaware Code Title 25Il-preview mhux disponibbli.

While residential landlords in Delaware are burdened with numerous mandatory disclosures (such as the Attorney General's Summary of the Code), commercial landlords face very few state-mandated disclosure requirements.

In Delaware commercial real estate, the prevailing legal principle is caveat emptor (let the buyer/lessee beware). The burden of due diligence falls heavily on the commercial tenant before signing the lease.

General Contract Principles and Good Faith

Although there is no checklist of statutory disclosures for commercial properties in Delaware's Title 25, commercial landlords must abide by the implied covenant of good faith and fair dealing inherent in all contracts.

This means a commercial landlord cannot actively commit fraud or intentionally conceal a severe, latent defect in the property that they know would materially impact the tenant's ability to operate their business, and which the tenant could not have reasonably discovered through their own due diligence.

Zoning and Code Compliance

Generally, it is the tenant's responsibility to verify that the property is zoned appropriately for their intended business use and that the building complies with ADA (Americans with Disabilities Act) regulations. However, if a landlord knows a specific business use is entirely illegal at that location and actively promises the tenant otherwise to secure the lease, this could be construed as fraudulent misrepresentation.

Federal Disclosures: Lead-Based Paint

The most prominent required disclosure for commercial spaces stems from federal law, not state law.

If the commercial property was built prior to 1978, the landlord may be required to disclose the presence of lead-based paint. This is strictly required if:

1. The commercial building includes any residential living spaces (like an apartment above a storefront).
2. The commercial space will be utilized as a "child-occupied facility" (such as a daycare center, preschool, or pediatric clinic).

If applicable, the landlord must provide the EPA-approved lead hazard information pamphlet, disclose any known lead-based paint, and include a specific lead warning statement in the lease for the tenant to sign.

Environmental Disclosures

While not always a strict statutory disclosure prior to leasing, commercial landlords and tenants must heavily negotiate liability surrounding hazardous materials. Often, a commercial landlord will require the tenant to disclose any hazardous materials they plan to use on-site. Conversely, sophisticated tenants often require the landlord to disclose Phase I or Phase II Environmental Site Assessments to prove the property isn't built on contaminated soil before signing a long-term commercial lease.

The "As-Is" Clause

To minimize disclosure liability, Delaware commercial landlords heavily use "As-Is" clauses in their lease agreements.

A properly drafted As-Is clause states that the tenant has independently inspected the premises and accepts the property in its current condition, relieving the landlord of any warranties regarding the property's fitness for a particular purpose. While powerful, an "As-Is" clause generally does not protect a landlord from claims of active, intentional fraud.

Best Practices for Commercial Landlords

1. Be Honest About Material Facts: If you know the roof needs total replacement and leaks during every storm, disclosing this upfront (and negotiating who pays for it in the lease) is vastly preferential to being sued for fraud and business interruption later.
2. Require Tenant Inspections: Include lease language explicitly stating that the tenant was given the opportunity to inspect the property, verify zoning, and test systems prior to signing.
3. Use Estoppel Certificates: When purchasing an occupied commercial building, require existing tenants to sign estoppel certificates disclosing what they believe the current lease terms and outstanding landlord obligations are to prevent future surprises.
