Key areas to watch include triple-net leases (NNN), which shift the financial burden of taxes, insurance, and maintenance onto tenants. Hidden maintenance costs, such as vague “common area maintenance” (CAM) fees, can also lead to disputes if not clearly itemized. Additionally, landlords may exclude liability for costly repairs, like HVAC systems or roof maintenance. To protect your interests, request a detailed breakdown of maintenance obligations and negotiate terms that limit your responsibilities to minor, routine repairs. For CAM fees, consider asking for an annual cap or the right to audit expense reports to ensure transparency.
