Data Center Land Option Agreements: Key Terms for Landowners

An option agreement is a contract in which the landowner (the optionor) grants a buyer (the optionee) the exclusive right to purchase the property on agreed terms during a fixed period. The buyer pays for that right. If it exercises the option, the parties move to closing under the purchase terms already written into the agreement or an attached purchase and sale agreement. If it does not, the option lapses and the landowner keeps the property.⁴

Data center developers rely on options because almost everything that makes a site valuable is uncertain on the day they find it. Developers typically use the option period to evaluate title, environmental conditions, electrical service and utility interconnection, water availability, engineering feasibility and local permitting.¹ That work can take a long time, sometimes years, because utility load studies and rezonings move on their own schedules.¹²

Data center deals also differ from an ordinary farm or commercial land sale. They commonly bring in zoning approvals, utility regulation, water rights, environmental compliance and tax planning, all on one parcel.² An option lets the developer carry that uncertainty for a modest payment instead of the full purchase price. That is a fair trade for both sides only if the option terms price the landowner’s lost flexibility properly. Our guide to buying, optioning or leasing data center land compares the option with the other structures developers use.

An option must be supported by real consideration to be enforceable. There is no legal floor or ceiling on the amount; it is negotiated.⁴ What matters to a landowner is less the headline number than how the money is structured.

• Refundability. Option fees are typically non-refundable if the buyer does not exercise.⁴ Watch for drafts that make early payments refundable until diligence ends. A refundable deposit gives the landowner little for tying up the land.
• Escalation. Landowner advisers recommend option payments that rise with each extension, so the cost of holding the land grows as the developer’s certainty grows.¹
• A signing payment. A non-refundable payment at signing, separate from later extension payments, is one of the terms landowner counsel commonly push for.³
• Credit against price. Many options apply some or all payments to the purchase price at closing. That is normal, but it means the true premium to the landowner is only the payments that are not credited, so price the non-credited share deliberately.

Option payments are often all a landowner ever receives, because many options lapse when power or zoning does not come through. A useful test: if the developer walks away on the last possible day, would the payments received fairly compensate for the years the land was off the market and the restrictions you accepted? If not, the payment schedule needs work. How payments compare with a market land price is covered in what drives data center land value.

Developers ask for long terms because power and entitlement timelines are long. One public example: in North Dakota, a developer of large data center campuses with on-site gas generation signed options with three Morton County landowners that gave it the exclusive right to buy for one year, with the option to extend up to three more years. The agreements did not obligate the company to buy.⁵

Landowner advisers recommend a definite expiration date that cannot drift.¹ In practice, that means checking the draft for:

• A fixed outside date that applies no matter how many extensions are exercised.
• Extensions that each require a payment made by a specific date, with the option ending automatically if a payment is missed.
• No open-ended “tolling” language that pauses the clock while the developer waits on a utility, county or lawsuit, unless you agree to it and are paid for it.
• A limit on how long the due diligence period inside any later purchase contract can run.³

During the option the developer will want to enter the property for surveys, soil borings, wetland delineation, environmental sampling and utility routing. Expect requests for an ALTA survey, a Phase I ESA and a geotechnical investigation, and sometimes for consent to rezoning or utility applications filed in the landowner’s name.

Access provisions should protect the working use of the land. Landowner advisers recommend that options expressly allow planting, harvesting, grazing, drainage maintenance, conservation practices and participation in USDA programs until closing.¹ Unless the agreement allocates responsibility for crop damage, drainage tile repair, gates, fencing and restoration, the producer may bear real losses from diligence work.¹² Practical terms to ask for include:

• Advance notice before entry and limits on where and when crews may work.
• Repair and restoration of any damage caused during diligence.³
• Insurance and an indemnity from the developer for its contractors’ work on the land.
• Copies of third-party reports, which have value to the landowner if the option lapses.
• Limits on restrictions the option places on the owner’s use of the property before closing.³

If the land is enrolled in preferential agricultural assessment, a change of use can trigger rollback taxes. Pennsylvania counsel, for example, list liability for “Clean and Green” rollback among the points to settle in the option.³ See our guide to agricultural tax status and rollback taxes.

An option is only as good as the purchase terms it locks in. Because the option may be exercised years after signing, a fixed price set today can look low by the time of closing if the site gains power commitments or zoning. The core question is whether the price reflects the land’s value today or shares in what power commitments and approvals make it worth.

Beyond price, the purchase terms usually address transfer tax allocation, the scope and survival period of the seller’s representations and warranties, and closing costs.³ Look carefully at any retained land: if you are keeping adjoining acreage, the deal may need terms on access, utilities, drainage and buffers. Our guides to due diligence periods and purchase contingencies and letters of intent cover the steps on either side of the option.

Many data center options are signed by a development entity that may later sell the project, or assign the option to an affiliate, a capital partner or an end user. One law firm reports that assignment clauses have become heavily negotiated in land access agreements for wind, solar and other infrastructure projects.⁷ Landowner advisers recommend meaningful limits on assignment.¹ Common middle grounds are free assignment to affiliates, landowner consent for other transfers, and a requirement that any assignee assume all obligations in writing.

Structures also vary. Some AI and data center projects combine a ground lease with an option to purchase rather than using a stand-alone option.⁸ The ground lease guide covers that path.

On termination, the agreement should require the developer to release any recorded memorandum promptly, withdraw applications filed for the property, restore the land and deliver studies. Data center options frequently become public. In Nebraska, the Flatwater Free Press reported in 2026 that a state senator had signed an option giving Tenaska the exclusive right to buy about 80 acres of his land, with data centers and a power plant both mentioned as possible uses; he filed a conflict disclosure the day after reporters asked about it.⁶ Plan on neighbors learning of the deal before closing; see confidentiality and project code names.

A data center option can run to twenty pages or more with exhibits.³ Options are frequently drafted to maximize the developer’s flexibility while restricting the landowner, and most of the issues are governed by state law, so independent counsel is worth the cost.² A landowner’s leverage is greatest before signing, so settle the important terms then.

1. 01Learn what the site is worth for this use: power proximity, zoning path and buildable acres drive value, and a site review or our screening tools can frame that before you negotiate.
2. 02Fix the outside date, payment schedule and escalation before negotiating anything else.¹
3. 03Write in farm-use rights, restoration duties and rollback tax responsibility.¹³
4. 04Limit assignment and require assumption of obligations by any assignee.⁷
5. 05Define what happens on termination: release, restoration, reports.
6. 06Have a real estate attorney in your state review the full draft and exhibits.⁴
