When the sign comes down,
the law does not pay you.
Federal statute names exactly who is compensated when a board is removed: the owner of the sign, and the owner of the land. The advertiser who paid for the flight and the production is not in the statute at all. Every billboard page in this category sells you reach. None of them mentions that.
Built for home services contractors, franchise systems and private equity portfolios buying out-of-home in the markets they actually serve — HVAC, plumbing, roofing, remodeling and the trades.
Out-of-home is one channel inside an AI-first program. We measure a board by the lift it produces in branded search, direct calls and whether AI assistants and search engines start naming your business in that market — because awareness nobody can trace is awareness you cannot defend at renewal.
We buy out-of-home for HVAC, roofing, plumbing and remodeling operators, for franchise systems and for private equity portfolios — one market or fifty. Unlike a traditional out-of-home shop we will tell you when a board is the wrong buy, when a market is already saturated, and when the money belongs in paid search instead. Most agencies sell you placement and defend it annually. We sell measurable presence and report the lift, or the absence of it, every month.
Contractors still buy boards for one good reason: in a service area your trucks already drive daily, repeated presence makes you the company a homeowner recognizes when the roof finally fails. We buy boards that produce measurable lift for HVAC, roofing, plumbing and remodeling operators, for franchise systems and for private equity portfolios — and we tell you when a board is the wrong buy, which no traditional out-of-home shop will do. Most agencies sell placement. We sell placement tied to branded search, call volume and AI visibility in that market, and we report the lift or the absence of it.
What Actually Governs a BoardNobody controls billboards. Four documents do.
Sign placement along the Interstate and primary highway systems is controlled by federal statute, administered by your state, and recorded permit by permit. A media vendor's availability list touches none of that.
The reason contractors still buy boards is simple: in a defined service area, a well-placed board makes you familiar to the same households your trucks drive past every day. That familiarity is what a homeowner draws on when the roof finally goes. Where we differ from most agencies is that we treat the board as one input to a measurable program rather than as a brand expense that gets defended annually — and the regulatory detail below matters only because a board that comes down early is money you never get back.
And out-of-home is measurable now in a way it never was. As an AI-first agency we watch what a board actually moves — branded search volume in the market, direct calls, and whether AI assistants and search engines start naming you when a homeowner asks who to call locally. A board that produces no lift in any of those is a board that produced awareness nobody can find.
Congress declared in 1965 that outdoor advertising next to the Interstate and primary systems should be controlled — to protect the public investment in those highways, to promote safety, and to preserve natural beauty. The mechanism is 23 U.S.C. 131, and the reach is specific: signs within six hundred and sixty feet of the nearest edge of the right-of-way that are visible from the main traveled way.
It is not a prohibition, and reading it as one is the first mistake. Inside that band, whether a sign may stand turns on the zoning class of the land beneath it. Areas zoned commercial or industrial under state law can carry signs, as can unzoned commercial and industrial areas determined by agreement. The states hold full authority to zone under their own laws.
The enforcement runs sideways rather than at you. Section 131(b) reduces a non-compliant state's federal-aid highway apportionment by ten per centum until it provides effective control, and the withheld money is reapportioned to other states. The statute does not police individual advertisers. It pressures the state, and the state pressures the structure.
Underneath the statute sits 23 C.F.R. Part 750, the implementing regulation, administered through the Federal Highway Administration's Outdoor Advertising Control program. Part 750 is where the two words that decide your exposure are defined — and they are not synonyms.
A sign out of compliance is either nonconforming or illegal. The difference is money.
Vendors use "grandfathered" for both. The regulation does not, and the gap between the two classes is the entire commercial risk in an outdoor buy.
Has a runway, and is paid for
- How it got there. Erected lawfully under the rules in force at the time, and later fell out of compliance when the rules or the corridor changed around it.
- What it gets. A defined removal period under the statute rather than immediate removal.
- Compensation. Just compensation is required on removal, with the federal share set at 75 per centum.
- Maintenance limits. Part 750 restricts what may be done to keep it standing — a nonconforming structure may not be substantially rebuilt.
- What it means for a buy. Predictable. If it comes down, there is a process and a payment.
No runway, no payment
- How it got there. Erected or maintained in violation of state law — no valid permit, wrong zoning, outside what the agreement allows.
- The sentence that does the work. Part 750 states that illegally erected or maintained signs are not nonconforming signs. The classes are mutually exclusive.
- What it gets. No removal period.
- Compensation. None. The just-compensation provision attaches to lawfully erected structures.
- What it means for a buy. The face can be removed with no process and no payment, mid-flight, after you have paid for production.
Four documents sit above every board. A rate card is not one of them.
Each answers a different question, each is publicly readable, and only the fourth is specific to the unit you are being sold.
Federal control of outdoor advertising adjacent to the Interstate and primary systems, measured from the nearest edge of the right-of-way and limited to signs visible from the main traveled way.
- It does not ban signs — zoning decides
- It does not police individual advertisers
- It reaches the state through apportionment, not fines
Part 750 defines an illegal sign as one erected or maintained in violation of state law, and a nonconforming sign as one lawfully erected that later fell out of compliance — then states that illegally erected or maintained signs are not nonconforming signs.
- Whether a removal period applies
- Whether compensation is owed at all
- Read it at eCFR Part 750
Each state negotiated its own agreement with the Federal Highway Administration covering size, lighting and spacing in zoned and unzoned commercial and industrial areas. What is permissible in one state is not automatically permissible across a border.
- A vendor operating in six states is under six sets of terms
- Ask which agreement governs the specific corridor
- Agreements are listed by FHWA
The first three describe the system. The permit describes the structure you are buying. It exists or it does not, and the state issuing agency holds it.
- Ask for the permit number and the issuing agency, in writing
- Ask whether the unit is permitted, nonconforming, or neither
- Treat an answer that avoids the permit number as an answer
Three conditions decide whether a structure is inside the controlled area.
The federal reach is narrower and more specific than most operators assume. It is not "near a highway" — it is a measured distance from a defined edge, a line of sight, and a zoning class.
What has to be true, in order
A sign falls inside the controlled area when it stands within six hundred and sixty feet of the nearest edge of the right-of-way along the Interstate or primary system, and is visible from the main traveled way. Inside that band, whether it may stand at all turns on the zoning class of the land beneath it.
- Distance from the right-of-way edge. Measured from the nearest edge of the right-of-way, not from the pavement — the two are not the same line and the difference decides borderline units.
- Visibility from the main traveled way. Judged from the road rather than from the lot. A structure screened from the traveled way sits outside the test even when it is inside the distance.
- Zoning class of the parcel. Commercial or industrial zoning under state law permits signs inside the band; unzoned commercial and industrial areas are determined by agreement.
- When the zoning was established. Whether the classification was in place when the structure went up, or arrived afterwards, is what separates a nonconforming unit from an illegal one.
- Whether a permit of record exists. For this specific unit, from the state issuing agency — the single question that resolves the class.
- Which agreement governs the corridor. Size, lighting and spacing terms differ by state under each Federal/State Agreement.
The rate card and the state's record are two different documents.
Three moments in an outdoor buy where a written answer costs nothing and changes what you are exposed to. None of them is a negotiation tactic; all three are documentation.
Establish what the structure is
- Ask for the unit's permit number and the issuing agency
- Ask whether the structure is permitted, nonconforming, or neither
- Ask which state agreement governs the corridor
- Treat an answer that avoids the permit number as an answer
Put the consequence where it belongs
- Ask what happens to your money if the unit is removed mid-flight
- Ask whether a make-good on a comparable unit is contractual or discretionary
- Separate the media cost from the production cost in the contract
- Keep the written permit answer attached to the contract file
Verify the buy actually ran
- Dated photographs of the posted face, not a rendering
- Confirmation the illumination schedule matched what was sold
- A record of any change of face or relocation mid-term
- A measurement design agreed before launch, not reconstructed after
Six rules every board runs to — and why each one exists.
The work is documentary before it is creative. Four of these are checks nobody runs, and two are measurement decisions that have to be made before the flight rather than after.
Permit of record, in writing
Permit number and issuing agency requested for every unit before a contract is signed.
Why: Part 750 makes the class turn on lawful erection. Without the permit you cannot tell which class you bought.
Class established before spend
Permitted, nonconforming, or neither — recorded against the unit in the buy file.
Why: nonconforming carries a removal period and compensation. Illegal carries neither. The difference is not visible from the road.
Removal risk written into terms
What happens to the media spend and the production cost if the unit comes down mid-flight, stated in the contract.
Why: Section 131(g) compensates the sign owner and the landowner. The advertiser is not named, so the contract is the only place that risk can sit.
Corridor agreement identified
Which state's Federal/State Agreement governs size, lighting and spacing on the specific corridor.
Why: a multi-market buy sits under multiple sets of terms. Assuming one national standard is how a compliant unit in one state becomes a problem in the next.
Measurement designed before launch
Matched markets or a holdout geography, a unique number and URL per channel, and a pre and post window agreed in advance.
Why: reconstructed attribution after the fact is not measurement. The design is covered under traditional marketing.
Delivery evidenced, not assumed
Dated photographs of the posted face, confirmation the illumination schedule ran as sold, and a record of any face change or relocation.
Why: you cannot verify what you bought without a record of delivery. Same discipline as media buying.
We ask for the permit number before we ask for the rate.
Every outdoor proposal we have reviewed leads with reach, impressions and a rate. None of them stated whether the unit was permitted. That is not a vendor being evasive — it is a question the industry does not ask, so the answer is rarely on file.
One written request changes the exposure. A vendor who can produce a permit number and an issuing agency has a documented structure. A vendor who cannot has told you something, and it costs nothing to find out before the artwork goes to print.
We will also tell you when outdoor is the wrong channel. It is a poor fit for a business that cannot service the geography it would be advertising into, and it is close to unmeasurable at low budget without a designed holdout. Saying so loses us the buy.
The statute names who gets paid. The advertiser is not on the list.
This is the finding that changes how an outdoor contract should be written, and it is one sentence of federal law that no billboard page in this category mentions.
| On removal of a lawfully erected sign | What the industry implies | AllegiantThe statute |
|---|---|---|
| Who is compensated | "You're covered" | The sign owner and the property owner, named at 131(g) |
| The advertiser's position | Not discussed | Not named in the statute at all |
| Production cost already paid | Assumed recoverable | Recoverable only if the contract says so |
| If the unit was illegal | "Grandfathered" | No removal period and no compensation |
| Make-good on a comparable unit | Verbal assurance | Contractual or discretionary — established before signing |
| How the class is established | Not established | Permit number and issuing agency, in writing |
Four outdoor line items you can stop paying for.
Two are numbers nobody can substantiate. One is a risk being quietly transferred to you. The fourth is a real service sold against the wrong measure.
Audience figures presented as measurements. Outdoor reach and frequency numbers are modeled from traffic counts and travel surveys. They are a reasonable planning input and they are not a count of people who saw your board. A rate card figure carried into a report as delivered impressions is an estimate wearing a measurement's clothes.
A buy with no permit question asked. This is sold by omission rather than deliberately. Nobody says "we did not check whether this unit is legal" — the question simply never comes up, and the risk sits with whoever paid for the production. One written request moves it.
"Grandfathered" as an assurance. The word has no regulatory meaning. Part 750 recognizes nonconforming and illegal, and states that illegally erected or maintained signs are not nonconforming signs. Ask which one it is.
Outdoor sold on brand awareness with no measurement design. Awareness is a real objective and it is not a substitute for a design. Without matched markets, a holdout, or unique response paths agreed before launch, there is nothing to read afterwards — and the campaign gets judged on a number reconstructed to fit.
The pattern beneath all four: the buyer ends up with no independent record of what they purchased or whether it legally existed.

Billboard advertising, answered against the source.
Answered against primary sources where they exist, and answered honestly where they do not.
Are billboards banned near highways?
No — they are controlled, which is a different thing. 23 U.S.C. 131 reaches signs within six hundred and sixty feet of the nearest edge of the right-of-way along the Interstate and primary systems that are visible from the main traveled way. Inside that band, signs may stand where the land is zoned commercial or industrial under state law, and in unzoned commercial and industrial areas determined by agreement. States hold full zoning authority. The page that argues the wider channel case is traditional marketing.
What is the difference between a nonconforming sign and an illegal one?
It is the difference between a runway with a payment and neither. 23 C.F.R. Part 750 defines a nonconforming sign as one lawfully erected that later fell out of compliance, and an illegal sign as one erected or maintained in violation of state law — then states that illegally erected or maintained signs are not nonconforming signs. Nonconforming units get a removal period and just compensation; illegal units get neither. Vendors call both "grandfathered." Related: media buying.
If the board is removed mid-flight, do we get our money back?
Only if your contract says so. Section 131(g) requires just compensation on removal of a lawfully erected sign and names who receives it: the owner of the sign, and the owner of the real property. The advertiser who paid for the flight and the production is not named in the statute. That is precisely why the removal scenario belongs in the contract terms rather than in a verbal assurance, and why media cost and production cost should be separated. This is general information, not legal advice. Related: CRM for keeping the record.
How do we check whether a specific board is legal?
Ask the vendor, in writing, for the unit's permit number and the issuing agency, and whether the structure is permitted, nonconforming, or neither. The state issuing agency holds the record; the FHWA Outdoor Advertising Control program administers the framework above it. An answer that describes the location, the traffic count and the availability without producing a permit number has answered a different question. Do this before production, not after. Related: competitor analysis on verifying claims at their source.
Why do the rules seem different in another state?
Because they are. Each state negotiated its own Federal/State Agreement with the Federal Highway Administration covering size, lighting and spacing in zoned and unzoned commercial and industrial areas. A structure that is permissible on one side of a border may not be on the other, and a vendor operating across several states is working under several sets of terms. For a multi-market buy, ask which agreement governs each corridor rather than assuming one national standard. Related: local SEO for the multi-market pattern.
What reach numbers should we expect from a billboard?
We do not quote them, and there are no reach or impression figures anywhere on this page. Outdoor audience numbers are modeled from traffic counts and travel surveys rather than measured, and no issuing authority publishes benchmarks for the medium. A modeled figure is a legitimate planning input and it is not a count of people who saw your board — carrying one into a results report turns an estimate into a claim you cannot support. The same reasoning governs conversion rate optimization, where Google's own guidance on evaluating third-party claims makes the parallel point.
How do we measure whether outdoor worked?
By designing the measurement before the flight, not reconstructing it afterwards. That means matched markets or a holdout geography, a unique phone number and URL for the channel, and an agreed pre and post window. Attribution assembled after a campaign ends is a story fitted to a result. The measurement design sits under traditional marketing, the tracked-number mechanics under landing pages, and conversions should be defined per Google's conversion documentation so the offline and online halves agree.
Is outdoor worth it for a local service business?
Sometimes, and we will tell you when it is not. It is a poor fit for a business that cannot service the geography the board reaches — a structure on a corridor forty minutes outside your service area generates calls you have to turn down, which costs more than the board. It is also close to unmeasurable at low budget without a designed holdout. Where it earns its place is sustained presence on a corridor your buyers actually travel, run long enough to matter and measured properly. Coverage questions belong with market research, which sources area data from the American Community Survey.
Does digital outdoor change any of this?
Not the legal position. A digital face still sits on a structure inside or outside the controlled area, and the permit, zoning and agreement questions are identical. What changes is that lighting and message-change terms become live issues, because those are exactly the provisions state agreements address. It also introduces a delivery-verification question a static face does not have: your creative shares the face on a loop, so ask for a record of the play schedule that actually ran rather than the one that was sold. Related: media buying.
Who actually enforces any of this?
The state does, and the federal government leans on the state to make it happen. Section 131(b) reduces a state's federal-aid highway apportionment by ten per centum until it provides effective control, and the withheld funds are reapportioned to other states. So enforcement reaches an advertiser indirectly — through a state agency acting on a structure, not through a penalty aimed at you. The practical consequence is that you can lose a face without ever having done anything wrong, which is the reason to establish the class before you commit. See website maintenance for the same detect-before-it-costs-you discipline.
