A tower can go in any zone here, but not without a hearing, and not within its own height of your line
A tower is allowed in every zone, and cannot be approved without a hearing
Fremont County's rule on wireless towers starts with a sentence that alarms people and a second one that should reassure them. Wireless telecommunication facilities are allowed in all zoning districts as conditional uses. And a new tower, or any change that raises a tower or its antenna apparatus by more than 25 percent, requires a Class II conditional use permit, which means a public hearing with notice to the neighbours.
So the answer to “could a tower go up next to my lot?” is yes, anywhere, and the answer to “would I find out first?” is also yes. The rest of Appendix O is the set of distances and conditions the applicant must meet, and for a neighbour they are the useful part.
“A fall zone: containing the telecommunication tower; clear of any dwellings on the parcel… and equal to 1.5 times the height of the tower shall be required… The minimum tower setback measured from the property line shall be equal to 100% of the telecommunication tower height.”
— Fremont County Development Code, 2011 Edition (Ordinance 2011-04), Appendix O sections 1.17.010 and 1.17.020. Consolidated through Ordinance 2026-03. Re-extracted from the county's live PDF 23 September 2026
The distances, which are all multiples of the height
| Rule | Distance | What it means for the lot next door |
|---|---|---|
| Fall zone | 1.5 times the tower height, clear of dwellings on the parcel (1.0 times in non-residential zones) | A 100-foot tower needs 150 feet of ground with no house in it |
| Property-line setback | 100 percent of tower height | A 100-foot tower stands at least 100 feet inside its own boundary; it cannot fall across yours |
| Roads, power lines, other buildings | Centre of tower at least 1.25 times total height from any transmission line, public road, railroad or building not on the site | The rule that keeps it off the road you use |
| Clear zone | All vegetation and combustibles removed for 50 feet from the base, or more if the fire code requires | A visible cleared circle, and a fuel break |
| Spacing | Preferably at least two miles from any other tower | The county's default is few and far apart |
| Co-location search | Must show the equipment cannot go on an existing structure over 60 feet within a one-mile radius | A new tower is the last resort, by rule |
An Idaho-licensed engineer may certify a different distance for any of the dimensional standards, and the county's fire code official may require a larger one. The distances are a floor with an engineer's escape clause, not a ceiling.
What the applicant has to bring, and post
- A project narrative showing by substantial evidence that a bona fide need exists and that no combination of other locations or technologies would remove the need or reduce the height and visual impact.
- Site plans by an Idaho-registered surveyor, landscape architect or engineer, showing the fall zone, every structure and utility on the parcel, and any existing tower whose fall zone reaches onto the property.
- Certification that the facility complies with FCC rules on electromagnetic emissions, and either that the FAA does not require it to be lit or painted, or that it will be lit and painted to FAA standards.
- At least $1,000,000 in general liability insurance, maintained until every above-ground part has been removed.
- A lease clause and a maintenance and removal agreement requiring every above-ground part to come down within 365 days of the facility ceasing operation, binding on successors, with the county authorised to do the work and recover the cost after notice.
- For a facility that does not add a new tower, a $5,000 cash bond to secure maintenance and removal.
Two further clauses matter locally. If the proposed tower is within two miles of Yellowstone National Park, the St. Anthony Sand Dunes, the Targhee National Forest, or any wilderness or wilderness study area, the applicant must send a copy of the application to the federal or state land manager before filing it with the county, and that manager has 60 days to comment. In Island Park, almost every conceivable site is within two miles of the national forest, so that review is close to universal here. And a permit is void if the facility is not built and in service within one year of both county approval and all federal approvals, extendable once.
What it will look like, by rule
The design section runs in order of preference. A tower shall be a monopole unless another design would blend better; after that, lattice, then other self-supporting designs, then guyed towers last. Antennas are mounted to present the smallest silhouette. Equipment enclosures may not exceed the height an accessory building would be allowed in the zone, and ground equipment is screened by vegetation. The whole facility sits inside a chain-link security fence of at least eight feet, which may carry barbed wire and must itself be screened by landscaping. Trees near the fence are pruned so nobody can climb them to get over it. Lighting is avoided where the FAA does not require it, and where it does, an aircraft-detection system that lights the tower only when aircraft approach is preferred.
The county also declares every improvement under this appendix to be personal property subject to assessment and taxation, and the application fee can be reduced where the applicant uses an existing publicly owned structure, sites outside a residential zone, or uses an existing tower without raising it.
Your own dish, antenna and mast are a different matter
None of this applies to the equipment an owner puts up to receive service. Section 1.02.020 says the appendix is not intended to regulate customer premise equipment or other personal-use structures for wireless reception or transmission; those are approved as accessory structures, including over-height ones for the parcel's zoning. The appendix also defers to federal pre-emption for personal radio, amateur radio and the FCC's over-the-air reception device rule. A satellite dish, an internet antenna on a mast, a ham operator's tower: accessory structures, handled the way the county handles any accessory structure, not Appendix O. On platted ground the covenants may say otherwise, and the plat is where to look.
If a tower application appears near your lot
- Find the parcel and the applicant — the county's parcel tools give you the ownership on every side.
- Take the proposed height and multiply. 1.5 times for the fall zone, 1.0 for the property-line setback, 1.25 for the road and building distance. If any of those crosses your boundary or your road, that is the fact to bring to the hearing.
- Ask for the co-location analysis. The applicant must show nothing over 60 feet within a mile could carry the equipment.
- Ask whether the forest was notified, since within two miles of the Targhee the land manager's 60-day review is a precondition.
- Read the conditions on the final approval, because a conditional use is a use the code allows only with conditions, and the conditions are where a neighbour's concerns end up written down.
Common questions
Can a cell tower be built in a residential zone in Fremont County?
Yes. Wireless telecommunication facilities are allowed in all zoning districts as conditional uses, and a new tower requires a Class II conditional use permit with a public hearing and notice to neighbours.
How far must a tower be from my property line?
The minimum setback from the property line equals 100 percent of the tower's height, so a tower cannot fall across a boundary. A separate fall zone of 1.5 times the height must be clear of any dwellings on the tower's own parcel.
How far must a tower be from a road or a power line?
The centre of the tower must be at least 1.25 times its total height from any above-ground transmission line, public highway or road, railroad, or building not on the site.
Would I be notified of a tower application?
Yes. A new tower or a modification raising a tower or antenna apparatus by more than 25 percent requires a Class II conditional use permit, heard at a public hearing with the county's notice requirements.
Does the county prefer new towers or shared ones?
Shared. A new tower may not be approved unless the applicant shows the equipment cannot be accommodated on an existing tower, building or structure over 60 feet within a one-mile radius, and towers should preferably be at least two miles apart.
What happens when a tower is abandoned?
All above-ground parts must be removed within 365 days of cessation of operations under a maintenance and removal agreement that binds successors. The county may do the work and recover the cost, and facilities without a new tower post a $5,000 bond.
Does the national forest get a say?
Within two miles of the Targhee National Forest, Yellowstone National Park, the St. Anthony Sand Dunes or any wilderness area, the applicant must send the application to the land manager first, and the manager has 60 days to review it before the county considers it.
What will a tower look like?
A monopole by default, with lattice, other self-supporting designs and guyed towers permitted only in descending order of preference. It sits inside an eight-foot chain-link fence that must be screened, with a 50-foot clear zone around the base and no lighting unless the FAA requires it.
Do these rules apply to my own satellite dish or antenna?
No. Customer premise equipment and personal-use structures for wireless reception or transmission are outside Appendix O and are approved as accessory structures, including over-height ones. Federal rules also pre-empt local regulation of over-the-air reception devices and amateur radio.
How much insurance must a tower operator carry?
At least $1,000,000 in general liability insurance covering construction and operation, maintained until all above-ground portions of the facility have been removed.
