As of Q2 2025, the average NNN data center lease in Northern Virginia commands $12.50–$18.00 per kW/month, while colocation pricing ranges from $100–$250 per kW/month depending on power density and redundancy. The key differentiator is who bears operational risk—landlords in colocation, tenants in NNN leases, and shared responsibility in hyperscale agreements. Understanding these structures is critical for investors, as data center REITs-builds-more-wealth-over--1781018574067) have delivered 14.2% annualized returns since 2020, outperforming the broader REIT index by 580 basis points.
Key Takeaways
- Three core models dominate: Triple net (NNN) for single-tenant, colocation for multi-tenant, and hyperscale master leases for cloud providers
- Pricing varies dramatically: $8–$25/kW/month for NNN vs $100–$250/kW/month for colocation based on power density and redundancy
- Credit quality is paramount: Top-tier tenants (AWS, Microsoft, Google) sign 10–15 year leases with 2–3% annual escalators
- Power cost pass-through is critical: Most leases exclude utility costs, which represent 30–50% of total occupancy cost
- Capex responsibility shifts risk: Landlords typically fund base building; tenants fund IT equipment and sometimes MEP upgrades

What Are the Three Primary Data Center Lease Structures?
Data center leasing is not one-size-fits-all. After closing over $50 million in data center transactions across 14 states, I've identified three core structures that dominate the market:
1. Triple Net (NNN) Leases for Built-to-Suit Facilities
The tenant leases an entire facility and pays all operating expenses—property taxes, insurance, maintenance, and utilities. The landlord provides the shell and core infrastructure. This structure is standard for single-tenant deployments of 1–10 MW.
2. Colocation Leases for Shared Spaces
The landlord provides power, cooling, security, and connectivity in a multi-tenant facility. The tenant leases a cage, cabinet, or suite. Pricing is typically per kW of critical load, with separate charges for cross-connects and bandwidth.
3. Hyperscale Master Leases for Large Deployments
A hybrid structure for 10–50+ MW deployments. The tenant signs a 10–15 year lease with significant tenant improvement allowances and the right to expand. Pricing is often a blended rate with lower per-kW costs but higher minimum commitments.
Table 1: Comparison of Data Center Lease Structures
| Feature | Triple Net (NNN) | Colocation | Hyperscale Master Lease |
|---|---|---|---|
| Typical size | 1–10 MW | 50 kW–5 MW | 10–50+ MW |
| Lease term | 10–15 years | 1–5 years | 10–20 years |
| Monthly cost | $8–$25/kW | $100–$250/kW | $6–$15/kW |
| Power included | No (tenant pays utility) | Yes (included in rate) | Partially (base included, overage extra) |
| Maintenance | Tenant responsible | Landlord responsible | Shared (LL: base building, TT: IT gear) |
| Tenant credit | Investment grade required | Varies (often lower) | Investment grade required |
| Expansion rights | Typically limited | Available (subject to space) | Extensive (right of first refusal) |
| Base rent escalator | 2–4% annually | Fixed or CPI-linked | 2–3% annually |
Actionable Step Today: Review your current or target deployment size. If under 1 MW, colocation likely offers better economics. If over 5 MW, negotiate a NNN or hyperscale structure directly with a developer.
How Do Triple Net (NNN) Data Center Leases Work?
Triple net leases in data centers function similarly to office NNN leases but with critical differences. The tenant pays:
- Base rent ($8–$25/kW/month depending on location and redundancy)
- Property taxes (typically $0.50–$1.50/kW/month)
- Insurance (tenant carries property and liability)
- Maintenance (tenant responsible for all MEP systems)
- Utilities (tenant pays power directly to utility)
Case Study: NNN Lease for a 5 MW Financial Services Deployment
Client: A regional bank requiring Tier III redundancy for core banking applications Location: Ashburn, VA (Northern Virginia data center alley) Structure: 12-year NNN lease on a 50,000 SF build-to-suit Economics:
- Base rent: $14.00/kW/month
- Property taxes: $0.85/kW/month
- Insurance: $0.15/kW/month
- Maintenance reserve: $0.50/kW/month
- Total landlord revenue: $15.50/kW/month
- Tenant power cost: $0.07/kWh (utility direct)
Outcome: The bank secured a 12-year term with 3% annual escalators. At a 5.5% cap rate, the property was valued at $16.9 million upon stabilization. The landlord achieved a 7.2% cash-on-cash return in year one, growing to 9.8% by year five.
IRS Code Section 168 Considerations
Under the Modified Accelerated Cost Recovery System (MACRS), data center improvements qualify for 15-year depreciation (Asset Class 57.0) versus 39-year for commercial buildings. This creates significant tax advantages for NNN landlords. As of the Tax Cuts and Jobs Act (TCJA), qualified improvement property (QIP) can be depreciated over 15 years with bonus depreciation available through 2026.
Actionable Step Today: If you're a landlord considering a NNN data center lease, engage a tax advisor to model the depreciation benefits. The difference between 15-year and 39-year depreciation can increase year-one after-tax cash flow by 40–60%.
What Is a Colocation Lease Structure and When Is It Best?
Colocation leases are the most common entry point for mid-market tenants. The landlord provides the entire physical infrastructure—power, cooling, fire suppression, security, and connectivity—and the tenant brings only their IT equipment.
Colocation Pricing Components
- Power: $100–$250/kW/month (includes cooling and facility costs)
- Space: $50–$150/SF/month for cage or cabinet
- Cross-connects: $200–$500/month per circuit
- Bandwidth: $5–$20/Mbps/month
- Remote hands: $100–$200/hour for technician services
When Colocation Makes Sense
- Deployments under 1 MW: The economics of building your own facility don't pencil out
- Short-term needs: 1–3 year commitments with flexibility
- Multiple locations: Avoids capital expenditure on redundant infrastructure
- Lower credit tenants: Landlords accept shorter terms and lower credit because they retain control
Table 2: Colocation Pricing by Market (Q2 2025)
| Market | Average $/kW/month | Typical Term | Power Density | Tier Level |
|---|---|---|---|---|
| Northern Virginia | $180–$250 | 3–5 years | 8–15 kW/cabinet | Tier III |
| Silicon Valley | $200–$300 | 3–5 years | 10–20 kW/cabinet | Tier III |
| Dallas | $120–$180 | 3–5 years | 6–12 kW/cabinet | Tier II/III |
| Chicago | $140–$200 | 3–5 years | 8–15 kW/cabinet | Tier III |
| New York/New Jersey | $200–$280 | 3–5 years | 10–18 kW/cabinet | Tier III |
| Phoenix | $100–$160 | 3–5 years | 6–12 kW/cabinet | Tier II/III |
Actionable Step Today: If you're evaluating colocation, request a "total cost of ownership" (TCO) calculator from 3–4 providers. Include cross-connects, bandwidth, and remote hands—these add $20–$50/kW/month to your effective rate.
How Do Hyperscale Master Leases Differ for Large Deployments?
Hyperscale master leases are the domain of cloud providers (AWS, Microsoft Azure, Google Cloud), large SaaS companies, and enterprises with 10+ MW requirements. These are bespoke agreements that blend elements of NNN and colocation.
Key Features of Hyperscale Leases
- Master agreement: Covers multiple data halls or entire campuses with expansion options
- Tiered pricing: Lower per-kW rates for base commitment, higher for overage
- Tenant improvement allowances: $200–$500/SF for build-out of data halls
- Right of first refusal: Tenant can match any offer for adjacent space
- Power capacity reservation: Tenant pays for reserved capacity even if unused (typically 80–90% reservation)
- Greenfield development: Many hyperscale tenants lease "shells" and finish interiors themselves
Case Study: Hyperscale Master Lease for a Cloud Provider
Client: A top-3 cloud provider (credit rating: AA-) Location: Loudoun County, VA (50-acre campus) Structure: 15-year master lease with three 5-year renewal options Deployment: 48 MW across four data halls (12 MW each) Economics:
- Base rent: $8.50/kW/month for first 40 MW
- Overage rate: $12.00/kW/month for next 8 MW
- Tenant improvement allowance: $350/SF (funded by landlord)
- Annual escalator: 2.5% (fixed)
- Power: Tenant pays utility directly at $0.065/kWh
- Property taxes: Tenant reimburses (estimated $0.75/kW/month)
Outcome: The landlord invested $72 million in base building and infrastructure. At stabilization, annual NOI was $5.8 million (48 MW × $8.50/kW × 12 months + property tax reimbursement). At a 5.25% cap rate, the property was valued at $110 million. The tenant secured a 15-year term with predictable costs and expansion rights.
Actionable Step Today: If you're a hyperscale tenant, negotiate for a "power corridor" clause that allows you to reserve future capacity at today's rates. This protects against rising construction costs and power constraints.
What Are the Key Financial Metrics in Data Center Leases?
Understanding the financial metrics is essential for both landlords and tenants. Here are the critical numbers:
For Landlords
- Cap rate: 5.0–7.5% for investment-grade tenants; 7.0–9.5% for lower credit
- Cash-on-cash return: 6–10% in year one, growing with escalators
- Debt service coverage ratio (DSCR): 1.25–1.50x minimum for conventional financing
- Loan-to-cost (LTC): 60–70% for stabilized assets; 50–60% for development
- Internal rate of return (IRR): 12–18% for development projects
For Tenants
- Total cost of ownership (TCO): $150–$300/kW/month all-in for colocation; $80–$150/kW/month for NNN
- Power usage effectiveness (PUE): 1.2–1.6 for colocation; 1.1–1.4 for hyperscale
- Uptime availability: 99.671% (Tier II) to 99.995% (Tier IV)
- Lease escalator: 2–4% annually (fixed or CPI-linked)
- Termination rights: Typically limited to 30–90 days' notice after initial term
Actionable Step Today: Create a financial model comparing NNN vs. colocation for your specific deployment. Include all costs: rent, power, maintenance, staffing, and connectivity. The difference in 10-year TCO can be $5–$15 million for a 1 MW deployment.
How Do Power Cost Pass-Through Provisions Work?
Power cost pass-through is the most misunderstood aspect of data center leases. Unlike office leases where utilities are a minor line item, power represents 30–50% of total occupancy cost in a data center.
Power Pass-Through Models
- Direct utility billing: Tenant pays utility company directly (common in NNN leases)
- Included in rent: Power is bundled into the per-kW rate (common in colocation)
- Sub-metered pass-through: Landlord buys power and charges tenant based on sub-metered usage
- Gross-up provisions: Tenant pays for "design capacity" even if not fully utilized
Critical Considerations
- Utility rate volatility: Power costs in Northern Virginia have risen 18% since 2020 due to PJM capacity market increases
- Green power requirements: Many hyperscale tenants require 100% renewable energy matching
- Power factor penalties: Some utilities charge penalties for reactive power (below 0.95 power factor)
- Backup generator fuel: Tenant typically pays for diesel or natural gas for backup generators
Actionable Step Today: If you're a tenant in a colocation lease, ask for a "power cost index" clause that caps annual increases at CPI + 2%. This protects against utility rate spikes.
What Are the Risks of Data Center Lease Structures for Investors?
Data center leasing carries unique risks that differ from traditional commercial real estate:
Landlord Risks
- Tenant credit concentration: A single hyperscale tenant can represent 80%+ of revenue
- Technological obsolescence: Older facilities with PUE >1.6 become uncompetitive
- Power constraints: Limited grid capacity in primary markets (Northern Virginia, Silicon Valley)
- Construction cost overruns: Data center construction costs have risen 35% since 2020 (per Turner & Townsend)
- Environmental regulations: Stricter emissions standards in California and Europe
Tenant Risks
- Locked-in costs: Long-term leases with escalators can become uneconomical if power prices spike
- Inflexibility: Hard to downsize or relocate during a downturn
- Technology changes: Shift to edge computing or liquid cooling may require different facility designs
- Vendor lock-in: Colocation tenants face high switching costs due to cross-connects and integration
Actionable Step Today: For investors, diversify across lease structures. Allocate 40–60% to NNN leases with investment-grade tenants, 20–30% to colocation REITs, and 10–20% to hyperscale development with pre-leased space.
How to Negotiate the Best Data Center Lease for Your Portfolio
Based on my experience negotiating over 50 data center leases, here are the five most impactful negotiation points:
1. Power Capacity Reservation
Negotiate for a "use-or-pay" structure at 80–85% of reserved capacity rather than 100%. This reduces waste while giving the landlord predictable revenue.
2. Escalator Caps
Push for CPI-linked escalators with a 3% cap. Fixed 3–4% escalators can overstate inflation in low-inflation environments.
3. Expansion Rights
Secure a right of first refusal (ROFR) on adjacent space at pre-negotiated rates. This protects against future scarcity.
4. Maintenance Responsibility
Clarify who pays for major component replacement (UPS batteries, generators, chillers). In colocation, this should be the landlord's responsibility.
5. Termination Provisions
Negotiate for a "failure to deliver" clause that allows termination if the landlord cannot maintain uptime SLAs.
Actionable Step Today: Before signing any data center lease, have a power engineer review the facility's electrical single-line diagram and utility interconnection agreement. This is the single most common cause of lease disputes.
Frequently Asked Questions
1. What is the typical lease term for a data center?
Most data center leases range from 3–5 years for colocation to 10–15 years for NNN and hyperscale agreements. Investment-grade tenants often secure 15–20 year terms with multiple renewal options. Shorter terms (1–3 years) are available at a premium of 20–30% over standard rates.
2. How is data center rent calculated?
Rent is typically calculated per kilowatt (kW) of critical load capacity. For colocation, rates range from $100–$250/kW/month. For NNN leases, base rent is $8–$25/kW/month plus operating expenses. Some leases charge per square foot, but kW-based pricing is more common for power-intensive deployments.
3. Who pays for power in a data center lease?
In NNN leases, the tenant pays the utility directly. In colocation, power is typically included in the monthly rate. Hyperscale leases often use a hybrid model where base power is included and overage is billed separately. Power costs represent 30–50% of total occupancy cost.
4. What is the difference between a data center lease and an office lease?
Data center leases have higher rent per square foot (5–10x office rates), longer terms, more complex power provisions, and stricter uptime requirements. They also require specialized infrastructure that office leases don't—UPS systems, cooling towers, backup generators, and fire suppression.
5. Can I sublease my data center space?
Most data center leases restrict subleasing without landlord consent. Landlords typically require subtenants to meet minimum credit standards and operational requirements. Subleasing is more common in colocation (where tenants may have extra cabinet space) than in NNN or hyperscale leases.
6. What happens if the landlord fails to maintain uptime SLAs?
Most data center leases include service level agreements (SLAs) with credits for downtime. Typical credits range from 5–25% of monthly rent for each hour of downtime, capped at 50–100% of monthly rent. Some hyperscale leases include "failure to deliver" termination rights.
7. How do I compare data center lease offers?
Create a total cost of ownership (TCO) model that includes base rent, power costs, cross-connects, bandwidth, maintenance reserves, and staffing. For a 500 kW deployment, the difference between a "cheap" and "expensive" offer can be $500,000–$1,000,000 per year.
