Atlanta, GA· Sign installation & permitting

Sign installation in Atlanta: how it really works.

Atlanta's sign ordinance lives inside its zoning code (Chapter 16-28A), is administered by the Office of Buildings' Zoning Division, and contains a requirement that's vanishingly rare anywhere else in the country: after an illuminated sign goes up, the applicant has ten days to take a light-meter reading at the nearest residential boundary and swear to the result in a notarized affidavit. It's a market where the paperwork follows the install — and where district overlays quietly rewrite the rules block by block.

What makes Atlanta different

The lighting affidavit and field test: illuminated-sign applicants sign a notarized affidavit on lighting intensity, then must measure the foot-candle level at five feet above ground at the nearest residential-district boundary within 10 days of installation and submit a second notarized affidavit attesting compliance. The permit doesn't certify the lighting — the applicant does, after the fact.
Hard per-storefront caps: a maximum of three building signs per ground-floor establishment (only one suspended or projecting), with combined area limited to 10% of the establishment's front wall and no single sign over 200 square feet.
Special Public Interest (SPI) districts carry their own sign codes inside the ordinance — Downtown's SPI-1 prohibits general advertising signs and limits projecting signs per frontage, and Midtown's SPI districts publish separate sign standards. A program that clears general commercial zoning can fail inside an SPI footprint.
Historic and landmark properties need a Certificate of Appropriateness from the Atlanta Urban Design Commission before the sign permit, with commission-level items heard on a twice-monthly public calendar.
An electrical permit is required for all illuminated signs — stated in bold on the city's own sign application.
The BeltLine Overlay, contrary to assumption, adds no sign standards of its own: its signage section simply refers back to Chapter 16-28A for the underlying zoning.

Who permits what in Atlanta

Office of Buildings, Zoning Division — under the zoning code

Atlanta's sign regulations are Chapter 16-28A of the zoning ordinance, administered through the Department of City Planning's Office of Buildings. Applications carry both a zoning inspector approval and a traffic approval, and the package includes the sign erector's business license and liability-insurance confirmation where signs project over the public sidewalk.

Illuminated signs: electrical permit plus UL documentation

Every illuminated sign requires an electrical permit alongside the sign permit, and internally illuminated signs are documented by UL number in the application package — then certified in the field through the lighting affidavit process.

The typical permit process

01Screen the address for SPI districts and historic/landmark designation — both change the standards and the sequence.
02If historic or landmark: obtain the Certificate of Appropriateness from the Urban Design Commission (staff-level review handles minor work; commission items go to public hearing).
03Submit through the city's Accela-based online permitting portal: scaled street-front elevations, sign renderings, site plan for freestanding signs, erector's license, insurance confirmation where applicable, UL numbers for illuminated signs, and the notarized affidavits.
04Pull the electrical permit for illuminated work.
05Install — then complete the foot-candle measurement at the nearest residential boundary within 10 days and file the second notarized lighting affidavit.

Districts and overlays that change the rules

SPI-1 Downtown and the Midtown SPI districts

District-specific sign regulations embedded in the ordinance — SPI-1 bans general advertising signs and tightens projecting-sign and portable-sign allowances; Midtown publishes its own sign standards under its SPI chapters.

Historic & Landmark districts

The Atlanta Urban Design Commission (or its preservation staff for minor work) issues the Certificate of Appropriateness that must precede the sign permit.

BeltLine Overlay District

A useful myth-bust: the overlay's signage section defers to Chapter 16-28A rather than adding standards — BeltLine-adjacent addresses follow their underlying zoning.

On timelines

The city publishes no sign-specific review timeline. Its general permitting materials indicate initial plan reviews on the order of ten business days per reviewing agency, with each correction cycle adding time — which is why the complete-first-submission discipline matters more here than any expediting trick. Historic and SPI reviews run on their own calendars in front of that.

What adds review, time, or cost

Illumination — electrical permit, UL documentation, the notarized lighting affidavit, and the 10-day post-installation field test.
Historic or landmark designation — Certificate of Appropriateness, possibly on the commission's public-hearing calendar.
SPI district location — district-specific prohibitions and tighter allowances.
Projection over the public sidewalk — additional requirements including liability-insurance documentation.
Sign count and area — the three-sign, 10%-of-facade, 200-square-foot ceilings are checked against existing signage, not just the new sign.

Documented exemptions include signs inside a building (if otherwise compliant), approved historic markers, and signage not visible from the public right-of-way on large private campuses. The exemption list is narrow; assume exterior commercial signage is permitted work.

How Signavero runs Atlanta

Signavero builds Atlanta's after-the-install obligations into the install itself: our closeout for an illuminated Atlanta sign includes the field light reading at the residential boundary and the notarized affidavit, filed inside the 10-day window — alongside the photo QA we run everywhere. SPI and historic screens happen at survey, so the design that goes to fabrication is the design the district can approve.

Questions people ask

What is Atlanta's sign lighting affidavit?

A two-part, notarized obligation none of the other major markets we track imposes: applicants for illuminated signs swear to the sign's lighting intensity at application, then — within 10 days of installation — measure the actual foot-candle level five feet above ground at the nearest residential-district boundary and file a second notarized affidavit attesting compliance. Skipping the field test leaves the sign out of compliance even with a clean permit. We fold the reading and filing into closeout.

How many signs can one Atlanta storefront have?

In general districts, up to three building signs per ground-floor establishment, only one of which may project or be suspended, with all signs together capped at 10% of the establishment's front wall and no single sign over 200 square feet. The math counts existing signage, so a survey of what's already on the facade comes before design.

Does the BeltLine add extra sign restrictions?

No — and that's worth knowing because it's widely assumed. The BeltLine Overlay's signage section simply refers back to Chapter 16-28A for the property's underlying zoning. The overlays that genuinely change Atlanta signage are the SPI districts and the historic districts, both of which we screen for at survey.
