The Closet Outside the Meter: Negotiating Communications Power in US Commercial Leases

A US commercial lease can be mathematically precise about rentable square feet and still be vague about the electricity that runs the tenant's communications stack. That vagueness is not accidental. Telecom closets, distributed antenna systems, rooftop antennas, and shared communications rooms often sit at the boundary between landlord-controlled building systems and tenant-controlled technology. When the meter stops at the suite door, the communications load can disappear from the tenant's utility bill and from the landlord's operating expense review.
The result is a cost that is real but unattributed. The tenant pays for it indirectly through operating expense pass-throughs, or the landlord absorbs it and recovers it through higher base rent. Either way, neither party can manage what neither party can measure.
Find the metering boundary
The first task is to map the lease's utility provisions against the actual communications topology. The lease may define premises, building systems, common areas, and utility services in ways that predate the current network design. A telecom closet that serves only one tenant may be treated as common area. A rooftop antenna may be classified as building equipment. A PoE switch that powers tenant access points may sit on landlord power because the closet is landlord-controlled.
The audit should list every communications room, switch, access point, antenna, UPS, and small-cell or distributed antenna component, then identify which meter serves it. If the answer is unclear, the lease language is unclear. That is the finding.
Clauses to read closely
Several lease provisions deserve scrutiny. The utilities clause should state whether electricity is separately metered, submetered, or included in gross rent. The operating expense clause should define what costs are recoverable and whether communications equipment is excluded. The alterations clause should address tenant-installed cabling and equipment in landlord-controlled spaces. The roof rights clause should clarify antenna power and access. The HVAC clause should address supplemental cooling for closets.
Also review the audit rights provision. A tenant that cannot inspect the landlord's utility bills or submeter data cannot verify a pass-through. The data access clause matters as much as the allocation formula.
Request data before negotiation
Before the next renewal, ask for twelve months of interval data for the relevant meters and submeters. Request a schematic of the communications power distribution, including which panels and circuits serve telecom rooms. Ask whether the landlord has separate submetering for communications loads and, if not, whether it will install it.
A practical request is not adversarial. It can be framed as part of a joint energy review: the tenant wants to understand its load, and the landlord wants to avoid disputes over pass-throughs. If the landlord cannot provide interval data, propose a temporary measurement plan using clamp meters or smart PDUs in the communications rooms. The cost of measurement is usually small compared with the cost of a multi-year allocation dispute.
A negotiation playbook
The first move is to separate base building power from tenant communications power in the lease schedule. The second is to define a allocation method for shared communications rooms, such as square footage of equipment footprint, measured circuit load, or a fixed monthly allowance. The method should be auditable and should include a true-up mechanism.
The third move is to secure data rights: monthly consumption reports, access to submeter data, and the right to install tenant-owned metering in tenant-controlled spaces. The fourth is to address changes in technology. A lease signed before a Wi-Fi 7 refresh may not contemplate higher PoE loads or additional closet cooling. The communications power clause should require notice and cost allocation when equipment changes materially increase load.
Finally, set a renewal calendar. Start the audit at least nine to twelve months before the lease expires. Landlords are more flexible when there is time to install submetering or amend schedules. A last-minute request invites a default to the existing pass-through.
This is not legal advice, and lease terms vary by state and property type. But the operational principle is consistent: if the communications stack consumes power, the lease should say who pays for it, how it is measured, and who can see the data. Otherwise the closet outside the meter becomes a recurring blind spot in both the energy budget and the tenant-landlord relationship.
