Recovery of past CAM overcharges depends on your specific lease terms, including any audit rights deadlines or ‘binding and conclusive’ provisions, and on applicable state law.

State statute of limitations periods apply to written contracts and range from 3 to 10 years. Your actual lookback window may be shorter based on your lease.

Ground Lease

Last updated: April 2026

A long-term lease (typically 50 to 99 years) where the tenant leases only the land and constructs or maintains the building at its own expense. At lease expiration, the building usually reverts to the landowner.

Technical Definition

In a ground lease, the fee simple landowner leases the land to a tenant who builds and operates improvements on it. The tenant holds a leasehold interest and typically pays ground rent based on the land value, not the improvements. Ground leases are common for major commercial developments where the landowner wants to retain ownership while generating income. The tenant finances, constructs, and maintains the building. At expiration, improvements revert to the landowner unless the lease provides purchase options or renewal rights. Ground lease financing involves separate valuations of the fee and leasehold interests.

How This Gets Abused

A ground lessor includes CAM-style charges for "land maintenance" in addition to ground rent, passing through costs like property tax increases, landscaping, and road maintenance that should be included in the ground rent calculation.

Tenant Protection Tip

In a ground lease, ensure the ground rent includes all land-related costs or that pass-throughs are explicitly defined and capped. Negotiate purchase options at lease expiration to avoid losing the building improvements you financed.
