Arizona Commercial Landlord Required Disclosures

While residential landlords in Arizona face a long list of statutory disclosure requirements, commercial landlords have far fewer state-mandated disclosures. Because commercial tenants are considered sophisticated parties, courts rely heavily on the principle of caveat emptor (let the buyer/lessee beware) and the specific terms negotiated in the lease agreement.

However, commercial landlords are not entirely free from disclosure obligations. They must operate under the covenant of good faith and fair dealing, meaning they cannot actively conceal crucial information.

Material Facts and Active Concealment

The most significant disclosure obligation for a commercial landlord in Arizona is the duty to disclose "material facts."

A fact is material if a reasonable person would attach importance to it when deciding whether to lease the property. A landlord cannot actively conceal a known defect or issue that would significantly impact the tenant's intended use of the property.

Examples of potentially material facts include:

• Zoning Issues: If the landlord knows the tenant's intended business use is prohibited by local zoning ordinances, they should disclose this. While tenants are expected to perform their own due diligence, actively misleading a tenant about zoning can lead to liability.
• Structural Defects: Known, hidden defects that render the property unsafe or unusable for the intended commercial purpose.
• Environmental Hazards: Knowledge of soil contamination, asbestos, or other severe environmental issues on the property.

If a landlord fraudulently conceals a material defect they knew about at the time the lease was signed, they can be held liable for damages, even if the lease states the property is accepted "as is."

Federal Disclosures

Lead-Based Paint Disclosure

Despite being a commercial property, if a portion of the building was constructed before 1978 and includes any residential areas (such as an attached apartment or a mixed-use building), or if the commercial space is used for child-occupied facilities (like a daycare), federal law requires the landlord to:

1. Disclose the known presence of lead-based paint and/or lead-based paint hazards.
2. Provide tenants with any available records or reports pertaining to lead-based paint.
3. Provide tenants with the EPA pamphlet "Protect Your Family From Lead In Your Home."

The "As-Is" Clause

Many Arizona commercial leases include an "As-Is" clause, stating the tenant accepts the property in its current condition with no warranties from the landlord. While these clauses are generally enforceable between commercial parties and place the burden of due diligence on the tenant, they do not protect a landlord who commits outright fraud or intentionally conceals a known, dangerous material defect.

Best Practices for Commercial Landlords

To minimize risk and foster a positive landlord-tenant relationship, consider these best practices regarding disclosures:

1. Be Transparent: While not legally required to point out every minor flaw, disclosing significant, known issues upfront prevents costly litigation later.
2. Require Tenant Due Diligence: Ensure the lease explicitly states that the tenant has inspected the property, verified zoning compliance for their intended use, and accepts the premises based on their own investigation.
3. Use Specific Disclaimers: If the landlord is unsure about certain condition (e.g., the roof), explicitly disclaim any warranty regarding that condition in the lease.
