Data Center Land Requirements
How Much Land a Data Center Needs, What Makes Land Qualify, and How Zoning and Permitting Work
A data center campus needs roughly half an acre to an acre per megawatt, but power, not acreage, decides how big it can be. Whether land qualifies comes down to power, zoning and a short list of physical checks. We assess sites against all of them.

Data center land requirements are the power, physical and approval conditions a parcel has to meet before a data center developer will buy or lease it. The planning rule most developers start from is about half an acre to one acre per megawatt of capacity, so a 100 MW campus needs roughly 50 to 100 acres and a gigawatt campus several hundred. A hyperscaler searching for a site through JLL in late 2025 asked for at least 200 acres with 400 MW of power, expandable to a gigawatt. Acreage is rarely the constraint, though. A parcel qualifies when it has contracted power on a date a buyer can underwrite, zoning that allows the use or a realistic path to it, and enough contiguous, buildable ground for the buildings, the substation, the generator and cooling yards and the setbacks. Most land that looks large enough fails on one of those, which is why the first question for any landowner is not how many acres they have but how many megawatts the site can get, and when.

How Much Land Does a Data Center Need?
Less than most landowners expect for the building, and more than most expect for everything around it. A data center's footprint is set by the megawatts it will draw, and a large share of the parcel goes to things that are not the data hall.
The buildings
The data halls themselves, usually in phases. Higher rack density puts more megawatts in each building, which shrinks the hall but not the rest of the site.
The substation
Above roughly 10 to 20 MW a campus needs its own substation, sized to the transmission voltage it connects at. A planned substation location on the parcel adds value. See powered land.
Generator and cooling yards
Backup generators, fuel storage, chillers and heat rejection grow with the megawatts, not the floor area, so dense AI campuses still need large yards.
Setbacks, stormwater and access
Required distances from property lines and neighbors, retention ponds, roads and parking. In counties that have tightened their rules, setbacks and screening take a growing share of the parcel.
| Campus type | Typical power | Typical land |
|---|---|---|
| Enterprise or edge building | 1 to 10 MW | A few acres to about 10 |
| Colocation campus | 20 to 100 MW | Tens of acres to about 100 |
| Hyperscale or AI campus | 200 MW to 1 GW and up | Hundreds of acres, often assembled from several parcels |
What Makes Land Qualify for a Data Center
Data center buyers screen sites in roughly this order. A site that fails a deal-breaker rarely gets to the rest, which is why the first two cards are where most land is won or lost.
1Power
- Contracted megawatts with an energization date, not a letter that promises studyDEAL-BREAKER
- Voltage and distance to transmission (230 kV and above prices highest)
- Two independent feeds, or a path to them
- The utility's large-load tariff, collateral and minimum terms
2Acreage and shape
- Contiguous, buildable acres at roughly 0.5 to 1 per megawatt
- A shape that fits phased buildings, a substation and yards
- Easements, wetlands and slopes that cut the usable area
- Room to expand for a second or third phase
3Zoning and approvals
- Data center use by right, or a realistic path to approvalDEAL-BREAKER
- Height, noise and generator-testing rules
- Any moratorium, pending ordinance or recent denial nearby
- The local political temperature
4Water
- Supply and discharge capacity if the design uses water
- Local restrictions on industrial water use
- Whether a closed-loop design avoids the issue
5Fiber
- Distance to long-haul routes
- Diverse paths into the site
- Carriers on or near the parcel
6Physical risk
- Flood zone, seismic, wind and wildfire exposure
- Soil, slope and grading cost
- Air quality attainment status for generator permits
7Neighbors and access
- Distance to homes, schools and sensitive uses
- Road access for construction and heavy equipment
- A plan for noise, lighting and traffic before the hearing
Items marked "deal-breaker" stop most data center buyers on their own. Free to use with a link to this page.
Data Center Zoning
Data center zoning has moved from a formality to one of the two things, with power, that decide whether a site can be built. Many counties that once allowed data centers by right in industrial zones now require a special exception, a conditional use permit or a rezoning, with conditions on noise, generator testing, setbacks, building height, screening and water. A use that was permitted when a landowner bought the parcel may not be permitted when a developer applies.
| Approval path | What it means | What to expect |
|---|---|---|
| By right | The zoning already lists data centers as a permitted use | The strongest position; still subject to site plan review and any new ordinance adopted before the application |
| Special exception or conditional use | The use is allowed only after a public hearing and approval, usually with conditions | Months of process, a hearing neighbors can attend, and conditions that can change the site layout |
| Rezoning | The parcel's zoning has to change, often with a comprehensive plan amendment | The longest and least certain path; a recommendation can be reversed by a council vote |
| Moratorium | A temporary pause on new data center approvals while the jurisdiction writes rules | No path until it lifts, and the rules that follow are usually stricter than the ones before |
Data Center Permitting
Permitting runs alongside the power work, and the slower of the two sets the schedule. JLL puts the full path from land acquisition to a shovel-ready site at three to seven years.
Zoning approval
By right, special exception or rezoning, as above. Everything else waits on it.
Site plan and environmental review
Layout, setbacks, stormwater, wetlands and species review. Environmental findings can reduce buildable acres and add months.
Air permits for generators
Backup generators need air permits, and a site outside an air quality attainment area may struggle to get them. Hyperscalers now screen for this at the land stage.
Utility agreements and easements
The facilities agreement, collateral and the easements for transmission and fiber. See powered land for the power ladder.
Building permits
Usually the most predictable step, once the rest is in place.
Send the parcel and its current zoning. We read the ordinance, the comprehensive plan and the recent decisions nearby the way a developer's team will, and tell you what the path looks like before anyone spends on it.
What Data Center Land Is Worth
Power sets the price far more than acreage does. The same parcel can be worth farm value or a multiple of it depending on how far its power position has advanced.
| Site | Price per acre | Source |
|---|---|---|
| Lower-cost market, no power path | About $10,000 | Andril, via Data Center Knowledge, October 2026 |
| Same market, power path established | Six figures | Andril, via Data Center Knowledge, October 2026 |
| Powered land outside the top markets | $200,000 to $1 million | JLL, via Bisnow, January 2026 |
| Northern Virginia, entitled, no power | About $4 million | Avison Young, Q2 2026 |
| Northern Virginia, powered | $6 million and up | Avison Young, Q2 2026; Twin Creeks, Leesburg, 97 acres at about $6.3 million an acre, November 2025 |

From $45,000. Every assessment is scoped to the site, so the fee is set once we know what has to be verified on power, zoning and value.
Frequently Asked Questions
How much land does a data center need?
As a planning rule, about half an acre to one acre per megawatt of capacity. A 10 MW building needs roughly 5 to 10 acres, a 100 MW campus roughly 50 to 100, and a gigawatt campus several hundred. Setbacks, parcel shape, stormwater and phasing move the real figure.
How many acres does a hyperscale data center need?
Hundreds. A hyperscaler searching through JLL in late 2025 asked for at least 200 acres with 400 MW of power, expandable to a gigawatt. Gigawatt AI campuses commonly assemble several parcels to get there.
What are data center land requirements?
Contracted power with an energization date, zoning that allows the use or a realistic path to it, enough contiguous buildable acreage for the buildings, substation, yards and setbacks, plus water, fiber, low physical risk, air permit eligibility for generators and road access.
Is my land suitable for a data center?
Start with power: how many megawatts the utility can deliver, when, and on what terms. Then zoning, acreage and shape, water, fiber and physical risk. Most land that is large enough fails on power or zoning, so those are the first two things to establish.
Do data centers need special zoning?
Increasingly, yes. Many counties now require a special exception, conditional use permit or rezoning rather than allowing data centers by right, and attach conditions on noise, generator testing, setbacks, height, screening and water. Some have adopted temporary moratoriums while they write new rules.
What is a data center moratorium?
A temporary pause by a city or county on approving new data centers, usually while it writes new zoning rules. There is no approval path while it runs, and the rules that follow are usually stricter than the ones before.
How long does data center permitting take?
JLL puts the full path from land acquisition to a shovel-ready site at three to seven years, with zoning and the utility work running in parallel. A site already zoned by right with a signed utility agreement sits at the short end.
How much is my land worth to a data center developer?
It depends mostly on the power. In Northern Virginia, powered land has traded at about $6 million an acre, and JLL has put powered land in other markets at $200,000 to $1 million an acre against $10,000 to $30,000 before the data center rush. Our powered land guide covers prices and deal structures in full.
Do you buy land or broker land sales?
No. We assess sites at a fixed fee, paid by the landowner or developer, so you know what the site can serve and what it is worth before you sign anything. The sale or lease itself runs through your broker and counsel.
Assess Your Land
Send the location, the acreage, the current zoning and everything you have on power: utility letters, study results, the distance to transmission and gas. You'll hear back within 24 hours from the principal who would run the assessment, with a first read on whether the site is worth assessing in full. If it is not a data center site, we say so before you spend anything.
Contracted megawatts and a zoning path decide what land is worth to a data center. The acreage only sets the ceiling.
