Billboard Permits in Louisiana: Rules, Spacing and Fees

By Gabie Research · Updated Oct 12, 2026 · 7 min read

Short answer

In Louisiana, DOTD's Outdoor Advertising section issues billboard permits. A new face over 300 square feet costs $250, and renewal is $25 a year, due July 1. Signs must be 1,000 feet apart on Interstates. A face can be up to 1,200 square feet. Digital messages must hold at least 8 seconds.

  • DOTD's Outdoor Advertising section issues one permit per sign face. You can file online or on paper.
  • Fees run by face size. A face over 300 square feet is $250 to permit and $25 a year to renew.
  • Spacing is 1,000 feet on Interstates, 500 feet on freeways and 300 feet on other primary roads outside towns.
  • Faces top out at 1,200 square feet, 30 feet high and 60 feet long. A digital face tops out at 672.
  • I-49, the Atchafalaya Basin and part of I-10 are closed or limited. A 2025 bill for 1,000 ft spacing has not passed.

DOTD issues billboard permits in Louisiana. You need one permit for each sign face. A new face over 300 square feet costs $250, and renewal is $25 a year. Signs on Interstates must be 1,000 feet apart. Faces can be up to 1,200 square feet. DOTD's digital rule sets no spacing of its own.

Who issues billboard permits in Louisiana?

The state Department of Transportation and Development runs the Outdoor Advertising program in its Office of Operations. The phone is 225-935-0112. The same office controls junkyards.

You can file in DOTD's online Outdoor Permitting System. Or you can send the paper application to the DOTD district office for the site. A permit office in Baton Rouge then reviews it. DOTD does not post a review time; ask.

The law is R.S. 48:461 and the sections after it. The rules are in Title 70, Part III of the Louisiana Administrative Code. DOTD posts its copy dated March 20, 2011.

Which roads need a state permit?

The state controls the Interstate system and the primary system. The primary system includes the National Highway System. That follows federal law, 23 U.S.C. 131.

In urban areas, control reaches 660 feet from the road's edge. An urban area has 5,000 people or more. Outside urban areas, control reaches any sign built to be read from the road, even past 660 feet.

Some roads are closed or limited:

  • I-10 from LaPlace to the Jefferson Parish line
  • I-10 between the Atchafalaya Basin levees
  • I-310 in St. Charles Parish, between I-10 and the Mississippi River
  • Land between the Mississippi River and its levees, unless the DOTD secretary agrees in writing
  • Three state parkways: I-49, part of US 90, and Ambassador Caffery Parkway

On a parkway, a billboard is allowed only within 5,000 feet of a crossing highway. The local government must allow it. The site must be zoned commercial or industrial, or lie within 800 feet of a business.

Where can a billboard go?

A sign must sit in a zoned or unzoned commercial or industrial area. Zoned land needs comprehensive zoning. Strip zoning, spot zoning and variances for signs don't count. A city or parish zoning official must fill out DOTD's zoning supplement form.

Unzoned land needs a real business. The building needs 600 square feet or more, a foundation and utilities. It must be open 8 hours a day, 5 days a week, and have run for 6 months. Farms and homes don't count.

The unzoned area runs 800 feet out from the business. DOTD's rule and the federal agreement both say 800. The statute, R.S. 48:461.4, says 1,000. Ask DOTD which it applies.

A standard 14 x 48 foot bulletin is 672 square feet. It fits every limit above.

What are the digital billboard rules?

DOTD calls them changeable message signs. The rule is LAC 70:III.132:

  • Each message holds at least 8 seconds.
  • The change takes 4 seconds or less, with no look of movement.
  • No flashing, animation, scrolling or full-motion video.
  • The sign must freeze in place if it breaks.
  • Only conforming signs can go digital. Nonconforming signs can't.
  • On a stacked structure, you get one digital face per side.

The usual spacing applies, and the lighting rules ban glare. Louisiana's 8 seconds matches the figure FHWA recommended in 2007.

What does a permit cost?

Fees are per face and depend on size. These are the fees in LAC 70:III.149, checked October 12, 2026.

Face sizeNew or replacement permitAnnual renewal
1 to 100 sq ft$75$7.50
101 to 300 sq ft$125$12.50
301 sq ft and up$250$25

The new-permit fee covers 12 months while you build. Renewal is due July 1, and DOTD sends notice by April 30. If you haven't paid by July 31, the permit ends and the sign becomes illegal. You can ask for 30 more days before July 1.

Build without a permit and you pay three times the fee on top of it. DOTD can fine an illegal sign $100 a day if the owner ignores a notice. DOTD does not post a transfer fee; ask.

Do you need a license or bond?

We found no operator license or bond in the state law or DOTD's rules. Ask DOTD to confirm before you file.

Can you cut trees in front of a sign?

Sometimes. DOTD's visibility directive says it "may consider" trimming for legal signs. It does not promise a yes.

  • The sign must be at least 5 years old and legal.
  • Only trees within 500 feet of the sign may be cut.
  • You must replant. A licensed landscape architect draws the plan.
  • A bonded tree service does the cutting. No topping.
  • Permits are issued only from October 15 to April 15.
  • You must replace any tree that dies within a year.

DOTD does not post a fee for this permit; ask. The rules also bar new sign permits where trees already hide the view.

What about nonconforming signs?

A nonconforming sign was legal when built but fails today's rules. It must stay about the same. You may repaint, change the ad and replace parts. You may not add lights.

You lose the status if you add 25% or more to the face. You also lose it if you replace 50% or more of the upright supports. A sign blank for 12 months is abandoned. Ask DOTD before a repair. It must answer within 14 business days. If it doesn't, you may go ahead.

If the state removes a lawful sign, it must pay just compensation under R.S. 48:461.6.

Do you need a local permit too?

Yes. State law says signs must meet all local building codes and ordinances. Your zoning official must sign DOTD's form. A parish or city can add its own rules.

Has anything changed since 2024?

Not in the rules. The Cornell copy still shows the March 2011 text. In 2025, House Concurrent Resolution 3 proposed 1,000 foot spacing on all controlled roads. It also banned new stacked signs. The legislature's page lists it as pending in committee since May 19, 2025. It has not passed.

How do you apply for a billboard permit in Louisiana?

  1. Confirm the road is on the Interstate or primary system and not closed.
  2. Confirm the zoning, or find a business that meets the unzoned test.
  3. Measure spacing to other signs, interchanges and rest areas.
  4. Get the landowner's signature or a copy of the current lease.
  5. For zoned land, get the zoning supplement form signed by the local official.
  6. File online, or send the paper form to the district office. Include the fee.
  7. DOTD issues the permit or returns it with reasons.
  8. Build within 12 months. If the sign does not match the permit, you get 30 days to fix it.
