Crown Castle Fiber is the kind of carrier most small business owners have never heard of. They do not advertise. They do not sell to single-office retail. But if you are a 50-person mid-market business in a major metro, there is a real chance Crown Castle fiber is in your building or on your block.
This guide walks through what Crown Castle actually charges in 2026, where the negotiation room is, and how to tell if your contract is in line with the market.
Crown Castle Fiber heading into the Zayo close
Crown Castle Fiber is the fiber arm of Crown Castle Inc. (NYSE: CCI), but the most material 2025 ownership change is Crown Castle's March 13, 2025 agreement to sell its entire Fiber segment, with Zayo acquiring the fiber solutions business and EQT taking the small-cell piece for $8.5 billion in aggregate, with closing expected in the first half of 2026 subject to approvals. Crown Castle says the network includes about 90,000 route miles, about 44,000 on-net buildings, more than 1,100 connected data centers, PoPs and COs, and customers across roughly 31 states. Documented business markets include Atlanta, Miami, New York, Boston, Dallas, and Chicago.
The March 13, 2025 sale announcement is the dominant 2024-2026 event and frames every contract decision a Crown Castle customer makes today, since new 36 to 60 month contracts will likely transfer to Zayo before the end of the term and that is worth flagging in any contract review. On the billing side, Crown Castle's public terms and tariffs document a specific payment pattern: monthly recurring charges are invoiced in advance, invoices are due within 30 days, services can auto-renew for one-year terms unless notice is given, and late charges run at 1.5% per month on past due amounts, with disputed charges needing written notice within 60 days.
As of May 2026, Crown Castle does not publish a public business internet rate. Current enterprise fiber pages are consultation and quote driven.
What Crown Castle sells
Three product lines that show up on most bills.
- Lit fiber dedicated internet. Symmetrical speeds from 100 Mbps up to 100 Gbps. Real SLA. The flagship product for mid-market and enterprise.
- Dark fiber. Long-term lease of unlit fiber strands. Used by enterprises that want to light their own optics and run their own network.
- Wavelength services. Carrier-grade transport for businesses that need very high capacity between two specific sites.
Crown Castle is mostly a building-in or campus-fiber play. They are stronger in dense commercial districts than in suburban office parks. Their footprint is largest in the northeast, mid-Atlantic, southeast, and major Texas and California metros.
What you should be paying
These are dedicated internet ranges from current carrier wholesale data, marked up to typical retail. Crown Castle pricing usually lands at or slightly below these bands, since they sell direct to mid-market and skip the SMB markup layer.
Crown Castle Fiber and peers, typical retail (mid 50%)
Monthly recurring charge, dedicated internet access (DIA). Numbers are derived from current carrier wholesale quotes. Shown as a metro-tier band where city-level data is thin.
| Speed | Typical retail (mid 50%) | Sample size |
|---|---|---|
| 100 Mbps | $630 – $800/mo | n = 7 |
| 500 Mbps | $840 – $1,160/mo | n = 5 |
| 1 Gbps | $1,050 – $1,455/mo | n = 6 |
| 10 Gbps | $1,330 – $2,660/mo | n = 7 |
If your bill sits above the high end of the band, you are likely overpaying.
Analyze My Bill FreeFor enterprise contracts at 10 Gbps and above, Crown Castle is often more competitive than the incumbent carriers. A 10 Gbps DIA line from Crown Castle in a major metro typically runs $1,800 to $3,000 a month on a 36 to 60 month term. The same product from AT&T or Lumen is often $2,500 to $4,500.
Where the negotiation room hides
Crown Castle pricing is almost never published. There is no rate card on a website. Every quote is custom. That cuts both ways. It means you have no public benchmark, but it also means the price is more negotiable than a Comcast or Spectrum bill.
Three things move the price.
- Term length. A 60-month term is often 30 to 40 percent cheaper monthly than a 12-month term. If you know you are not moving offices for 5 years, the long term pays off.
- Capacity ramp. If you can commit to a 1 Gbps line today and a 10 Gbps upgrade in year three, Crown Castle will often discount both phases.
- Multi-site bundling. If you have offices in three or four cities and Crown Castle covers all of them, ask for a master service agreement with bundled pricing.
A competing quote from Lumen, Lightpath, or a regional fiber overbuilder is the strongest single piece of leverage. Crown Castle reps know who their direct competitors are in each market and will move on price to keep your business.
The four side charges to flag on Crown Castle bills
Enterprise fiber bills look different from SMB cable bills, but the side charges still add up.
- Carrier Cost Recovery Fee. Looks like a tax, is not. Crown Castle margin.
- Construction recovery. A monthly amortization of your install cost. Often runs the full term of the contract. Worth asking how much of your monthly bill is install recovery vs ongoing service.
- Equipment rental. $50 to $150 a month for managed routers or optical equipment.
- Static IP and BGP fees. Add up fast on multi-site enterprise contracts.
How Crown Castle pricing changes at renewal
Crown Castle contracts often run 36 or 60 months. The auto-renewal rate is typically held flat or close to flat, which is a friendlier renewal than the cable carriers. The catch is that the original contract rate is rarely the best rate they would offer a fresh customer.
- The window that matters is 90 to 120 days before contract end. Crown Castle contracts often have notice clauses that lock you in if you do not give written notice.
- A competing quote unlocks the new-customer rate at renewal.
- Asking for a capacity upgrade at renewal time is often the cleanest way to drop the per-Mbps cost without a full contract reshop.
