A ground lease is a long-term agreement in which a landowner rents out bare land to a tenant who then constructs and operates buildings on it, usually for 50 to 99 years, after which the improvements generally revert to the landowner. The structure separates ownership of the land from ownership of what sits on it, which is what makes the arrangement attractive to developers who want to deploy capital into construction rather than land acquisition, and to landowners who want steady income without giving up long-term ownership.
How a Ground Lease Works
The landowner (the ground lessor) keeps title to the land. The tenant (the ground lessee) gets the right to build and operate for the lease’s duration, and pays periodic rent for the land itself. Because the tenant is sinking real money into construction, the term has to be long enough to earn that investment back. Fifty years is a floor; 99 is common.
The split in ownership forces the lease to say exactly who handles property taxes, insurance, and maintenance. In practice, almost all of it lands on the tenant, which makes most ground leases function like triple-net leases.1Metro Transit. Ground Leases A Guide for Developers, Public Officials, and Lenders
At expiration, unless the parties have negotiated otherwise, the buildings and improvements revert to the landowner. That reversion is the defining feature of the deal and carries large financial consequences for both sides.1Metro Transit. Ground Leases A Guide for Developers, Public Officials, and Lenders
Where You See Them
Ground leases dominate large commercial projects: shopping centers, office towers, hotels, industrial facilities, and chain restaurants. They work especially well in high-cost urban markets where buying the land outright would be prohibitive, and in public-private partnerships where a government entity owns the ground and leases it to a private developer.
They also appear in affordable housing. Community land trusts buy land, sell the homes on it to income-eligible buyers, and keep the land under a long-term ground lease with resale restrictions that preserve affordability for future buyers. Monthly ground rents in these arrangements are set at affordable levels, and the leases must follow model documents from the National Community Land Trust Network or the Institute for Community Economics.2Fannie Mae.

Subordinated vs. Unsubordinated
This distinction shapes the risk profile of the whole deal.
In a subordinated ground lease, the landowner agrees to place the fee interest behind the tenant’s construction lender in priority. If the tenant defaults on the loan, the lender can foreclose on the land itself. Landowners take on real risk, but subordination is sometimes the only way the tenant can secure financing at all, meaning no subordination, no project, no rent.
In an unsubordinated ground lease, the landowner’s interest stays senior. A lender who forecloses can take the tenant’s leasehold and the buildings but cannot reach the land. Unsubordinated structures are more common. They protect the landowner, but they make financing harder for the tenant, and landowners who insist on this structure often accept lower rent as the trade.
How Rent Is Set and Escalated
Ground lease rent is typically calculated by applying a capitalization rate to the appraised value of the land. A parcel appraised at $1 million at a 5% cap rate produces $50,000 in initial annual rent.1Metro Transit. Ground Leases A Guide for Developers, Public Officials, and Lenders Cap rates vary by market, property type, and bargaining leverage.
Because these leases run for decades, rent set on day one will drift away from market reality. Escalation clauses address this in a few forms: fixed percentage bumps (say 2% a year), adjustments tied to the Consumer Price Index, or periodic rent resets based on a fresh appraisal of the land’s fair market value.3Law Journal Newsletters. Reset Clauses In Ground Leases Resets are the dangerous one. In a hot market, a reset can double or triple rent overnight. Tenants should push for caps on reset increases and appraisal methodologies that value the land alone, not the land plus the improvements the tenant paid to build.
Provisions That Matter Most
Construction Obligations
The lease will specify what the tenant must build, when construction starts and finishes, and what standards the improvements must meet. In larger projects, the contingency period for site plan approvals, parking ratios, permitted uses, signage, and stormwater can run long, and the tenant may owe non-refundable deposits to the landowner while working through them.
Insurance, Taxes, and Maintenance
Ground leases almost universally make the tenant carry liability insurance, maintain the property, and pay all property taxes.1Metro Transit. Ground Leases A Guide for Developers, Public Officials, and Lenders Many leases require insurance at full replacement cost with periodic reappraisals to keep coverage current.
Default and Cure
Default clauses define the breaches that can end the lease: non-payment of rent, lapsed insurance, violations of permitted use. Expect notice requirements and cure periods. Because any lender financing the tenant’s improvements has a major stake in keeping the lease alive, cure rights usually extend to the lender too, often with separate notice and the right to step in and fix defaults the tenant will not.
Condemnation
If the government takes the property, both landowner and tenant have compensable interests, and the lease should say how the award is split. Without a clear clause, the division goes through a legal apportionment based on each party’s proportionate interest. Some landowners try to insert waivers in which the tenant gives up all rights to condemnation proceeds. Courts generally disfavor these forfeiture provisions, though a waiver written in unmistakably clear language may be enforceable. Tenants should resist blanket waivers.
Financing a Building on Leased Land
Building on land you do not own is the central challenge of any ground lease deal, and the lease itself has to clear specific hurdles before a lender will fund construction.
Lenders want the unexpired term to outlast the loan by a safe margin. Fannie Mae, for example, requires the remaining lease term to exceed the mortgage maturity by at least five years. The lease cannot be terminated without giving the lender notice of any default and at least 30 days to cure it or begin foreclosure. A merger of the landowner’s and tenant’s interests cannot be allowed to extinguish the leasehold without lender consent.4Fannie Mae. Special Property Eligibility and Underwriting Considerations: Leasehold Estates
Other standard requirements: the lease (or a memorandum of it) must be recorded in public land records, the tenant’s interest must be freely assignable without the landowner’s consent, and the tenant must be barred from surrendering or modifying the lease without the lender’s written approval. For new leases, Fannie Mae also requires that no prior liens encumber the fee estate unless the lienholder has signed a non-disturbance provision protecting the lease.4Fannie Mae. Special Property Eligibility and Underwriting Considerations: Leasehold Estates Getting these protections into the lease before you go looking for financing is essential. Retrofitting them later with a reluctant landowner is much harder.
Tax Treatment for the Tenant
Tenants can generally deduct ground lease rent as an ordinary business expense, provided the payments are for property used in a trade or business and the tenant is not acquiring an equity interest in the property.5Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses The IRS treats it like any other business rent deduction: ordinary, necessary, and reasonable in amount.6Internal Revenue Service. Deducting Rent and Lease Expenses
Watch the structure. If payments are set up so that part of each one applies toward an eventual purchase, the IRS may recharacterize the deal as a conditional sales contract rather than a true lease. In that case the payments are not deductible as rent; the tenant depreciates the property over its useful life instead.6Internal Revenue Service. Deducting Rent and Lease Expenses Improvements the tenant builds are depreciated under the normal rules for the property type.
What Happens When the Lease Ends
The default outcome is reversion. The landowner takes title to everything the tenant built, and a building worth tens of millions can change hands without the landowner paying a dime, because that was the deal from day one.1Metro Transit. Ground Leases A Guide for Developers, Public Officials, and Lenders
Tenants who want a different ending have to negotiate it upfront. Renewal options give the tenant the right to extend under pre-agreed conditions. Purchase options give the tenant the right to buy the land at a set price or at fair market value. A right of first refusal requires the landowner to let the tenant match any outside purchase offer before selling.
Whatever protections are in the lease, the timing of their use matters. Tenants who wait until the final years to open discussions have almost no leverage. The common wisdom in the industry is to begin renewal or buyout talks 20 to 30 years before expiration. As the remaining term shrinks, the leasehold becomes harder to finance, harder to sell, and less valuable, all of which weaken the tenant’s position.
Risks to Weigh Before Signing
Ground leases work when both sides understand the tradeoffs. The risks are real and not always obvious at signing.
- Improvement reversion. The tenant builds it; the landowner eventually gets it. Over a 99-year lease this feels abstract, but as expiration nears it becomes very concrete.
- Rent escalation. A manageable rent on day one can turn punishing after a market-value reset. Caps and clearly defined appraisal methods are the main defenses.
- Financing difficulty. Lenders are cautious about leasehold mortgages because the collateral is a time-limited interest in someone else’s land. A ground lease with 20 years remaining is nearly unfinanceable for most purposes.
- Default consequences. Defaulting on a ground lease can mean losing not just the lease but every building and improvement on the property. Unlike walking away from rented space, the tenant walks away from property they built and paid for.
- Landowner trouble. If the landowner defaults on a fee mortgage or fails to pay taxes on the fee interest, the tenant’s leasehold can be jeopardized. Non-disturbance agreements and protections against fee-estate liens help, but only if they are negotiated in.
For landowners, the signature risk is subordination. Placing the fee behind a tenant’s lender can mean losing the land outright if the project fails and the lender forecloses. Refusing to subordinate protects the land but may make it hard to attract a tenant who cannot otherwise secure financing.
