Wireless infrastructure in Montgomery County is reviewed through a formal application process that most residents never see until construction begins.
This page helps residents locate existing and proposed cell towers and small cell installations, and takes a closer look at how individual applications are proposed, reviewed, approved, and ultimately built—using real examples from neighborhoods across the county.
If you are just starting out and want to know whether there is a tower near you, begin with the general search tools below. If you are trying to understand how and why a specific installation was approved, this page goes deeper.
Update 6/18/2026: The Montgomery County Transmission Facilities Coordination Group (TFCG) has a new website and URL which can be accessed at this URL: https://www.montgomerycountymd.gov/government/departments-agencies/technology-enterprise-business-solutions/office-broadband-programs/towers-antennas/towers-overview

How Cell Tower Applications Are Reviewed in Montgomery County
This guide was created by residents to help document and clarify key parts of the review process, including where to find applications, what information is available, and how decisions are made.
The Montgomery County Transmission Facilities Coordination Group (TFCG) receives and coordinates applications from wireless providers seeking to install cell towers and other wireless facilities. This guide was created by residents to help document and clarify where to find applications and related County information, which is often difficult to locate or interpret.
The Transmission Facilities Coordination Group (TFCG) is Montgomery County’s public-facing website for cell tower and wireless facility information. While it is the official source for applications, much of the most relevant information is difficult to locate without guidance.
On the TFCG website, you can find a link labeled “Wireless Locations,” but it is located near the bottom of the page and easy to miss. The site also features an interactive map of telecommunication facilities more prominently; however, this map is not consistently updated and may be inaccurate.
Application Databases and How to Use Them
What’s available
The TFCG website states that all applications received are publicly available online and can be accessed in two ways:
• an Excel download of the application database
• a dataMontgomery version of the same database, which allows for interactive viewing
Important limitations
The two versions of the database are not identical. At least one important field—“App_description”—is present in the Excel version but missing from the dataMontgomery version. Because of these differences, neither database alone provides a complete picture.
How residents should actually search
To locate proposed or existing wireless facilities and understand County siting decisions, it is often necessary to use multiple data sources together. In addition to the Excel and dataMontgomery databases, the Department of Permitting Services (DPS) dataset provides essential information about permits and construction activity.
We have created a map visualization using the dataMontgomery dataset and integrated the DPS data, which is available on our data visualizer page. Reviewing all three datasets together—the Excel database, the dataMontgomery database, and the DPS dataset—provides the most complete view of wireless facility siting in Montgomery County.
Below is a scroll-able view of the Excel database file published by the County on February 7, 2024 and located here: https://montgomerycountymd.gov/cable/Resources/Files/Towers/databases/MC%20Database%202_5_26.xlsx. Their database is often updated daily so be sure to get the latest download from the TFCG website.
TIP: We have created a map visualization using the dataMontgomery data set and made it available on our data-visualizer page and have added the crucial Department of Permitting Services (DPS) dataset to this visualization. To get an overall sample view of the number of towers and antennas within a 3 mile radius you can use this tool: Antenna Search, but note that it is best for large towers, macro cell sites, long-established, licensed antenna facilities. It is not designed to comprehensively capture: installations approved through local zoning / ROW processes rather than FCC tower registration, strand-mounted antennas, small cells attached to existing infrastructure, pole-top or wire-mounted equipment, recently installed neighborhood-level facilities.
Tips for using the Excel database.
Looking at column heading “D: ColoNewMM” you can see that applications can be made for things like a colocation, new installation or a modification. For a particular site location, there can be many data rows because there is a row created for each application. Over the years there can be many rows of applications added for a site.
The TFCG website states in their key that an application can have the following status terms (see column “W: Action” in the Excel database and column “10: Status” in the dataMontgomery version):
“Under Review”: The Application is currently being reviewed, but projected to be on next eligible TFCG agenda. This status must be reached a minimum of 7 days prior to a TFCG meeting in order to be heard before the committee.
“Pending – Not Complete”: Application has been submitted, but has not been deemed complete yet.
“Tabled”: The application is on hold, and is not currently being processed.
“Withdrawn”: The applicant has withdrawn the application, and it will not be processed.
“Recommended” and “Not Recommended”: Strangely, the TFCG key neglected to provide information about these status terms. However, the Tower Committee must, per MCC Div. 11D, Sec. 2.58E.(c)(3)(C), “recommend to any land use agency a decision on any pending siting issue, including any appropriate provisions governing removal of the facility after its useful life concludes and the posting of a bond to guarantee removal.”
Data Gaps, Omissions, and Record Integrity Concerns
“Recommended with conditions” is another status term not described in their key because they no longer provide this level of detail for the public on the Excel or the data Montgomery data table. You would have to look at the application review and TTFCG Action to see if there were any conditions listed.
Example from 2005: TTFCG Action “Recommended with conditions” from an application made for Oakview Recreation Assoc. for constructing a 120′ monopole with three 54″ panel antennas at the 120′ level.
“This recommendation is conditioned on approval of a Special Exception for this facility in a residential zone and a waiver of the setback requirements from the Board of Appeals for this monopole.” The excel database will have the status term “Recommended”. You wouldn’t know about the conditions unless you opened the PDF application and read the TTFCG Action.
Below is the Excel database excerpt: Under the “Action” column it says “Recommended” instead of “Recommended with conditions”. This omission of information keeps the public in the dark about cell towers that would not have been built if there weren’t special exceptions and waivers.
Excel excerpt showing loss of “with conditions”

Alterations to historical records
Despite resident objections, the TFCG staff and contract personnel routinely alter the Excel database and the dataMontgomery data set in ways that some of us believe should not be permitted since it is an official County record. This can be seen as deliberate falsification of County records.
Statement about flawed records management
Here are some examples of alterations we have seen the County TFCG staff and their contractors make:
- When the owner of the property changes, the record is altered to change the owner of the property to the new/current property owner for all entries back to the initial application, which could run over decades.
- When there is a change in the zoning of the property, staff makes the zoning for the property the current zoning for all entries back to the initial application.
Changes and erasures by the County or contractors that update record entries to current times and deviate from the facts at the time of the committee vote tamper with history and the record, can deceive the public, and constitute very flawed records management. Montgomery County residents deserve better!
Important Limitation: Public Records Do Not Confirm What Was Built
County wireless facility databases primarily document applications and review actions, not what was ultimately constructed in the field. There is no definitive, public, County-maintained source that allows residents to confirm whether a specific application resulted in a built installation, whether a proposed site was ever constructed, or whether a previously existing facility is still in place.
In practice, the only reliable way to determine whether wireless antennas or related equipment were installed at a specific location is through on-site visual inspection.
Even visual inspection has limits. Many wireless facilities—especially small cells, strand-mounted antennas, and equipment attached to utility poles or streetlights—can be difficult to identify. If antennas were added, replaced, or modified at an existing site, an observer on the ground may not be able to determine with confidence whether changes occurred, when they occurred, or under which application they were approved.
The County’s Wireless Antennas and Towers map may help identify locations where facilities are believed to exist, but it does not confirm whether a particular application resulted in construction, nor whether installations have since been modified or removed. It should be used as a general reference, not definitive confirmation of what was built.
No Comment-ing on Wireless Tower Applications
What has happened to the “Comment on Wireless Tower Applications” link?
( This link is currently inactive on the County’s website.)
— The last time we used this comment form, it had limited character input space and didn’t allow any hyperlinks, images or attachments. A Montgomery County resident that used the form said they did not receive confirmation that their comment was received. They also stated that they were able to infer that their request was completely ignored, if it was even reviewed or considered at all.
It may be best to email the committee members directly.
Public Participation Denied — Tower Committee Process
The Committee meets monthly, with industry reps in attendance and actively participating, to review and make recommendations on all applications. Although meetings are open to the public, there is no way for the public to actively participate in Tower Committee meetings. Telecom reps are permitted to speak; residents are not! Read the Parents’ Coalition of Montgomery County Article. Despite residents’ repeated requests, the recordings of the meetings are not made and archived. When residents have sought to record the meetings themselves, the Tower Committee chair has threatened them with criminal penalties.

Additional Information and TFCG Resources
Municipalities with Independent Review Authority
The TFCG does not review telecommunication applications for the following municipalities that are located in Montgomery County. These municipalities develop their own policies and review procedures regarding radio and telecommunication facilities. The applications must be submitted to the municipality for their review and approval.
- City of Gaithersburg
- City of Rockville
- Town of Barnesville
- Town of Brookeville
- Town of Laytonsville
- Town of Poolesville
- Town of Washington Grove
It is important to note that whenever a wireless telecommunication facility application concerns a county right-of-way that is located within any of these municipalities, then county telecommunication facility regulations apply.
dataMontgomery interactive database
The second button link on the Wireless Facilities Locations webpage is to the dataMontgomery version of the Wireless Siting Application Database. It loads in a data table. There are tools for creating filters and other types of visualizations, such as a map view of the data–which allows you to search by address or zoom in, hover over the nodes then click to access the data. We have created a video demo for using the map visualizer or you can view the custom visualization we created and saved.
Montgomery County Telecommunication Facilities MAP
TFCG web page provides a link to a map with the caption, “An interactive map of telecommunication facilities in Montgomery County. From experience, we can tell you that the County does not update this map frequently. We have seen it age a couple of years before it was updated. As of January 24, 2023 the date stamp says 11/10/22.
Some may find that this map is still useful. Tip: use the data layers on the map.

Strand Mount and Small Cell Applications
Wireless Telecommunications (Strand Mount) Locations. This page does not tell you any of the proposed or existing locations! The only way we are aware of to see which applications are specifically for Strand Mount antennas or related equipment, is to view the Excel version of the database, specifically, column “C: App_description”. This description field is where you will find the mention of strand antennas if it is part of the application. You can search the Excel database (ctrl f windows) for the word “strand”. Here is an example for application no. 2019010665 “Crown Castle is proposing to install a power supply cabinet to an existing 29′-2″ PEPCO wood utility pole (#793424-0998). The purpose of this installation is to supply power to small cell strand nodes that are located in the same vicinity as the power sup”
Other TFCG Web Resources: Department of Permitting Services (DPS) data set
Department of Permitting Services (DPS) data set. Since telecommunications facility coordination regulations were first adopted in 2003, these regulations have required a database that documents where each wireless facility is located. And for many years residents have complained that the TFCG database only documents wireless applications, but not the locations of the actual, permitted wireless installations. Finally, in late 2019, the County produced that dataset. The data shows each existing wireless antenna facility and the corresponding TFCG application.
Other TFCG Web Resources: mcatlas.org
The MCAtlas Map has layers, such as neighborhood boundaries, that you can toggle on and off. The map offers contours maps so that you can check the elevation of a proposed/existing wireless site and compare that elevation to the elevation of the property where someone is or would be impacted by the wireless facility. There is also a ruler for measuring distances.
Other TFCG Web Resources: mcatlas.org/antennazta
Like the MCAtlas map, the Antenna ZTA Map has layers you can toggle on/off and there is NO indication that the data is up to date.* Use this map to get an idea of how many thousands of potential new wireless “small” cell tower locations near our bedroom windows were just handed over to Big Wireless at MoCo resident expense with the passage of ZTA 19-07 and 22-01.

Examples of Cell Tower and Small Cell Installations in Montgomery County (Pre–ZTA 22-01)
On Rooftops
Dozens of wireless facilities on top of the roof of a multi-family residential building. Residents of color and immigrant communities disproportionately impacted.
To view the applications for rooftop cell tower buildings like this, download the Excel database and sort the “site name” column and search for the apartment or condo name.
In Yards Towering Over Houses
A 68′ high cell tower was installed at the wrong address and remains standing 12 years later. MoCo has a history of lax reviews and oversight.
Beside Apartment Buildings
A utility pole with top mount antenna and an attached equipment box 27′ from building. Residents’ rights to notice and hearings eliminated with the passage of ZTA 19-07 and 22-01.
Strand Mounted “Small” Cells attached to the Utility Wires
Strand refers to the metal strand between utility poles. As the name implies, the strand-mounted small cells are mounted on the strand, typically close to a utility pole. To the casual observer, the strand mounted small cell may look similar to other infrastructure mounted on strands, including the cable companies’ fiber splice boxes and amplifiers.

Blocking your view.
Did you know that in Montgomery County towers can be installed between less than 30 feet and as close as zero feet from homes after a hearing process?
The setback depends on whether your building is in a residential or commercial zone. Much of the County’s multifamily housing (e.g., condo or apartment) is in residential zones, where the setback is the same as for single-family homes (30 feet, or less after a hearing). In commercial or mixed use zones, the setback was previously reduced to only 10 feet under ZTA 18-02. If you’re not sure what zone your building is in, you can look it up here.

Lurking over your home and yard
That cell tower would almost blend in with the sky if the high voltage electric cables attached to the sides were painted a lighter color. The noise and diesel fumes from the backup generators might give it away though.
Public School Grounds
Monopoles have lots of room to co-locate more antennas and equipment–perhaps a financial enticement for the school board. Who is monitoring the cumulative radiation levels? Did you know that the applicant is only required to supply a computer simulation of antenna radiation? Applicants do not perform “real world” radiation testing.

Legislative Background and Zoning Changes (Context for the Process)
In 2025, the County Council passed Zoning Text Amendment ZTA 25-11 (Temporary Commercial Uses – Temporary Telecommunications Facility), which is now in effect: https://www.montgomerycountymd.gov/COUNCIL/Resources/Files/Ordinance%2020-26%20(ZTA%2025-11).pdf and effectively allow wireless companies to unilaterally decide when and where to put up cell towers – anywhere, anytime throughout the county, with no due process and no minimum setbacks. And in many cases, without even a building permit.
The Council adopted two zoning text amendments, ZTA 22-01 Antennas on Existing Structures (Oct 25, 2022) and ZTA 19-07 (Jul 27, 2021), despite widespread opposition from residents, environmental groups, and candidates in the primary election. 100% of the residents who signed up to testify or submitted written testimony opposed the latest zoning change.
The ZTAs reduce the antenna setback to 30 feet from homes and schools and apartments, allow cell tower antennas on street lights, utility poles, and new poles in residential neighborhoods and remove residents’ previous rights to notice and hearings — eliminating the community from the decision making process. In commercial or mixed use zones, the setback was previously reduced to only 10 feet under ZTA 18-02. Here are the top reasons why residents opposed ZTA 22-01 and want reform.
