Cell Tower Lease Due Diligence:
What to Check Before Signing

Rate Due Diligence: Is the Offer Fair?

The most important pre-signing check is verifying that the proposed rent is at or above current market rate for your specific location, property type, and carrier. National averages are too broad to be useful - you need verified comparable transaction data from your specific market.

Rate due diligence should include:

• Current market rate ranges for comparable property types in your city
• Recent comparable lease transactions for similar carriers in your market
• Verification that the proposed escalation clause (not just the base rent) is at market standard
• A model of total lease income over the full term under the proposed terms vs. market-standard terms
• Assessment of whether co-tenancy fees are included and at market rate

If the proposed rate is below market - which it almost always is on a first offer - this information gives you a documented, defensible basis for a counteroffer before you sign.

Legal and Title Review

Before signing a cell tower lease, several legal and title issues should be verified:

Clear title. Confirm that you have clear, unencumbered title to the property being leased. If there are outstanding liens, easements, or other encumbrances affecting the tower lease area, these should be resolved before signing.

Existing easements. Review existing easements affecting your property. Some easements may restrict the use of land for telecommunications infrastructure or create conflicting rights that could complicate the tower lease.

Mortgage or deed of trust. If your property has a mortgage, your lender almost certainly has a right to approve or restrict certain uses of the property. Some loan agreements require lender consent for long-term leases. Check your loan documents and obtain any required approvals before signing.

Zoning and use permits. Confirm that the tower use is permitted under current zoning, or that the carrier's responsibility for obtaining required permits is clear in the lease. Property owners sometimes find themselves involved in permitting processes they did not anticipate.

HOA or deed restrictions. Review any homeowners association rules, neighborhood covenants, or deed restrictions that might restrict tower construction on your property.

Counterpart Due Diligence: Who Are You Signing With?

Before signing a long-term lease, verify the financial stability and identity of your lease counterpart:

Confirm the entity. The lease should be with a legally identifiable, financially stable entity. Some tower companies use special purpose vehicles (SPVs) or subsidiaries for individual lease transactions. Ensure you understand which entity you are contracting with and that it has the financial capacity to fulfill its obligations.

Corporate guaranty. If the lease counterpart is a subsidiary or SPV, consider requiring a corporate guaranty from the parent company. This ensures that the financial obligations of the lease are backed by an entity with real assets.

Assignment provisions. Understand under what circumstances the carrier can assign the lease. Unrestricted assignment allows the carrier to transfer your lease to another entity without your consent. If possible, negotiate for prior written consent or at minimum prior notice for assignments.

Term and Renewal Review

Carefully review all provisions affecting the length of the lease relationship:

Total committed term. Calculate the maximum total term of the lease including all renewal options. On a 5+5+5+5+5 structure (5-year initial term with four 5-year renewal options), the total term is 25 years. Make sure you are comfortable with the total duration.

Renewal option mechanics. Understand how renewal options are exercised. Does the carrier need to provide notice? What is the notice period? What happens if they fail to exercise on time? These details determine your leverage at each potential renewal point.

Holdover provisions. Review what rent applies if the carrier continues using the site after lease expiration without executing a formal renewal. Ensure holdover rent is favorable to you - ideally at a defined premium rate.

Termination provisions. How and when can either party terminate? Be cautious of broad termination rights allowing the carrier to exit with minimal notice for any reason. Negotiate minimum terms and appropriate notice periods.

Environmental Considerations

Cell tower installations involve environmental considerations that property owners sometimes overlook:

Generator fuel storage. Many cell towers include backup generators with on-site fuel storage. Fuel spills or leaks create environmental liability. Ensure the lease requires the carrier to maintain environmental insurance and explicitly indemnifies you for any fuel-related contamination.

Electromagnetic field (EMF) concerns. Cell tower RF emissions are regulated by the FCC and are generally considered safe within regulated limits. However, some property owners in residential areas receive neighbor complaints about EMF. Ensure the carrier's lease includes broad indemnification for any claims related to RF emissions from their equipment.

Waste and hazardous materials. The lease should address responsibility for proper disposal of hazardous materials and electronic waste generated by the tower operations. Carriers should be responsible for proper disposal - not property owners.
