Murals vs. Signs: The Fine Line That Decides What's Allowed on Your Building

Drive through parts of South LA and you'll see it constantly: building-sized portraits of Nipsey Hussle, Kobe Bryant, and other figures who matter to the neighborhood's history, painted across walls that would otherwise just be blank retail frontage. It's some of the best public art in the city, and it raises a question I get from clients fairly often when they're building out a location: can I do something like that on my building? And more specifically — can I put my brand on it?

The answer comes down to a distinction Los Angeles built into law over a decade ago. In 2013, the city adopted a Mural Ordinance that created a legal category called an Original Art Mural — a one-of-a-kind, hand-painted, hand-tiled, or digitally printed image on the exterior wall of a building. If a mural genuinely qualifies as an Original Art Mural under the city's rules, it is explicitly not treated as a sign, which means it's exempt from the city's sign regulations entirely. That's a meaningful exemption, because LA's sign code is otherwise strict, especially around off-site and commercial advertising.

Here's the part that actually answers the branding question: if what you're putting on the wall doesn't conform to the Original Art Mural requirements, it isn't treated as art. It's treated as a sign, and it becomes subject to the full weight of sign regulations — permitting, sign district restrictions, and in many zones, real limits on what's allowed at all. The practical dividing line is usually about whether the piece functions as advertising. A striking piece of art that happens to be on your building is very different, legally, from a giant version of your logo painted across the same wall. The more the piece reads as promoting your brand or product rather than standing as a work of art in its own right, the more likely it gets reclassified as signage rather than a mural — and loses the exemption that makes murals appealing in the first place.

New murals generally require a building permit from the Department of Building and Safety, along with a registration process through the city's Department of Cultural Affairs. It's not a purely informal process, even though plenty of murals around the city clearly went up without anyone formally going through it — enforcement here, like with a lot of LA's code, is inconsistent in practice even where the rule is clear on paper.

If a mural is part of your build-out plan, the real work is making sure the concept reads as genuine art rather than dressed-up advertising before you commission it, not after it's already on the wall.
