Public art, street art and graffiti: the difference is permission
Public art relates to graffiti through exactly one variable: permission. Everything else people use to tell them apart, the style, the training of the person holding the spray can, the quality of the drawing, is unreliable, and the courts do not consider any of it. A commissioned mural and an unauthorised one can be made by the same artist in the same week on two walls a street apart, and they sit in completely different positions for ownership, liability, lifespan and removal. That distinction is why the question is worth a page: it decides who is insured, who can be prosecuted, who owns the image, who is allowed to paint over it.
The three way comparison
Comparing the three across five practical rows shows how much follows from the one variable at the top.
| Commissioned public art | Street art | Graffiti writing | |
|---|---|---|---|
| Who authorises it | Site owner and commissioner, in writing, usually with a planning or licensing consent behind it | Nobody, unless the wall owner has agreed, in which case it is commissioned work | Nobody |
| Who owns the copyright | The artist, as author, unless the contract assigns it | The artist, as author | The writer, as author, in principle |
| Who carries liability | Commissioner, site owner and artist, allocated by contract and insurance | The artist, criminally; the wall owner still carries the cost | The writer, criminally; the wall owner still carries the cost |
| Intended lifespan | Stated in the brief, from days to 25 years and more | Until it is painted over or weathers away | Days to weeks in a managed area |
| What happens on removal | A contractual and reputational process, sometimes a planning one | Removed at the owner’s discretion, no notice owed | Removed as a cleansing operation |
Street art and public art: where the line actually falls
Street art sits on the unauthorised side of the line with graffiti, not the commissioned side with public art, and this surprises people because the two are so different in reception. In UK law there is no category called street art. There is property belonging to somebody and marks made on it with or without that person’s agreement. A mural admired by a whole neighbourhood, photographed constantly and used in the local tourist literature is, if nobody asked the owner, in the same legal position as a tag on the same wall.
What separates street art from graffiti writing is reception rather than permission: an audience, a critical vocabulary, often a market. That is a real distinction and it changes how a council behaves, but it is not a legal one, and a commissioner who assumes otherwise will make a bad decision about a wall they do not own.
Commissioned murals that look like street art
Commissioned murals in a street art idiom are ordinary public art commissions wearing another form’s clothes, run on the ordinary rules. The artist has been selected, briefed, contracted and insured. There is a signed agreement with the wall owner, an access plan for the scaffold, a paint specification, an anti graffiti coating decision and a stated life. The visual language is borrowed. The process is not.
Three things go wrong often enough to be worth naming. The first is the wall: the owner’s consent must survive a change of owner, so the agreement needs to bind successors, or the mural disappears with the next sale. The second is the coating: a sacrificial anti graffiti coating protects the work but has to be renewed, and nobody funds it. The third is authorship: artists in this idiom often expect to be credited by tag, the commissioner expects a plaque, and neither raises it until the launch.
The wall owner’s rights, and the position in UK law
Unauthorised painting on someone else’s property is criminal damage in the UK, under the Criminal Damage Act 1971, and it remains criminal damage regardless of how good it is or how welcome the neighbours find it. The medium can bear on it in a way that merit never does: whether a mark is damage at all turns on permanence and the cost of restoring the surface, so a readily washed-off medium can fall outside the offence where paint does not. Local authorities also hold powers under anti social behaviour legislation to require graffiti to be removed from certain surfaces, which is why an owner sometimes pays to remove work they were content to leave.
Ownership then splits in a way that catches almost everybody out. The wall owner owns the wall. The artist owns the copyright in the image, because under the Copyright, Designs and Patents Act 1988 the author of a work is its first owner, and no rule makes the owner of the surface the owner of the artwork. So the owner may paint over the mural tomorrow, and may not put it on a T shirt. Whether an anonymous artist would enforce copyright in an unauthorised work is a separate question, rarely tested.
Moral rights follow from the same Act: the right to be identified as author, which has to be asserted, and the right to object to derogatory treatment. Neither prevents physical destruction. A UK commissioner can remove a commissioned mural without infringing moral rights; what they cannot do is alter it and leave the artist’s name on the altered version.
Does any of it require planning permission
Planning permission is normally required for a freestanding sculpture and normally not required for painting an existing wall, because painting a surface is not usually development. Three exceptions matter. Advertisement consent is needed where the painted work promotes a product, a business or an event, and the test is what it does, not what it is called. Listed building consent is needed for work to a listed building, and painting the wall of one without it is an offence. Conservation area status, and in Scotland the interest of Historic Environment Scotland in designated assets, adds scrutiny to anything visible in a protected setting.
Unauthorised work sits outside this entirely. Nobody applies for consent to commit criminal damage, which is another way of saying the consent regime is a practical marker of the difference: if a permission was sought, it was public art.
Why the distinction decides the budget
The commissioned route costs more because it buys certainty about all five rows in the table above. Consent, insurance, access equipment, a specified paint system, a maintenance regime and a written agreement about copyright and credit are the difference between a mural still legible in year ten and one painted over during a change of tenancy in year two with nobody at fault. A commissioner attracted to the immediacy and the price of unauthorised work is comparing a finished picture with a process, and the process is what they are buying.
