How Long Does It Take to Paint a Mural? Timelines by Project

A single interior feature wall takes two to four days to paint. A multi-room interior takes one to three weeks. A full building exterior takes three to four weeks on the wall, and inside the City of Los Angeles the permit that has to come first adds two to three months before the first coat. Those are the honest numbers; everything else on this page explains where the time goes and how to shorten it.

This is written from the painting side, not the sales side. The painting itself is rarely the slow part. Design sign-off, landlord or funder approvals, surface preparation and, for exteriors in Los Angeles proper, registration with the city are what set the calendar. If you are budgeting as well as scheduling, the 2026 Los Angeles mural pricing guide covers cost with the same candor.

The short answer, by project

Typical timelines for the kinds of work we paint most. Design and approval run before painting; painting days are working days on the wall; totals are from a signed brief to a finished, sealed wall.

Two things to read into that table. First, a wall outside Los Angeles proper often finishes months sooner than the same wall inside it, purely because of permitting; our Orange County page and the permit guide explain why. Second, the painting column barely changes between a modest and a large interior. What changes is everything around it.

Where the time actually goes

Design and revisions: one to two weeks. A concept, then a rendering of the artwork on a photograph of your actual wall, then revisions until it is right. This phase is only as fast as the decisions. One decision-maker turns it around in days; a committee turns it into a month.

Approvals: days to weeks, sometimes in parallel. Landlord consent on leased space, a funder’s sign-off on a school or community wall, brand approval from a marketing team. None of it is painting, and all of it has to happen before painting. We hand over the rendering early precisely because it is the document these approvals run on.

Permits: the big variable. An exterior mural inside the City of Los Angeles goes through the Original Art Mural registration, with a neighborhood notification window that alone adds weeks. Allow two to three months from brief to first coat, and start the paperwork the day the design is approved. Interiors need no permit anywhere, and most surrounding cities are lighter.

Preparation: one to three days. Cleaning, patching, priming and site protection. It is the least visible day on the schedule and the one that decides whether the wall still looks right in ten years; see how long a mural lasts.

Painting: the numbers in the table. Working days on the wall, which are not always calendar days. An office or restaurant painted evenings and weekends spreads four painting days across two weeks.

Coating and handover: one to two days. Exteriors get a protective coat that needs to cure before the wall is touched, then cleanup and photography.

What makes a mural take longer

Detail. Photorealism and fine lettering take multiples of the time of bold graphic work over the same area. This is the single biggest lever on painting days, and the one most people underestimate.

Surface. Corrugated metal, unsealed block and rough stucco each need more preparation than smooth drywall, and some need primers with their own drying time.

Access. Height, a wall that faces a busy sidewalk, a loading bay in use, or a room that can only be painted after closing all stretch the calendar without adding painting hours.

Weather. Exterior paint has temperature and moisture limits. Los Angeles is forgiving most of the year, but a wet week in winter or a marine layer that does not lift on the coast can cost days.

Decisions. Every revision round and every late stakeholder adds a week somewhere. The projects that finish fastest are the ones where the person who signs off is in the first meeting.

A realistic schedule for a commercial exterior in the City of Los Angeles

  1. Week 1. Brief, site visit, proposal and agreement.
  2. Weeks 2 to 3. Concept and rendering on the actual wall, revised to approval. Registration paperwork and owner sign-off start the moment the design is approved.
  3. Weeks 3 to 12. The city’s notification window and registration run. Nothing happens on the wall, so this is the time to settle logistics, materials and dates.
  4. Weeks 12 to 13. Surface preparation, then painting begins. A full elevation runs three to four weeks; a single exterior wall runs several days.
  5. Week 16, roughly. Protective coating, cleanup, photography and the reveal.

Outside the City of Los Angeles the same project usually collapses to six to eight weeks, because weeks 3 to 12 largely disappear.

A realistic schedule for an interior feature wall

A brief in week one, a rendering signed off in week two, preparation and two to four painting days in week three, and a finished wall by the end of the month, painted around your opening hours. The Toastique branding mural in Downtown Los Angeles was finished before the doors opened, then completed live on the influencer night; that is the shape most openings take. Office interiors follow the same pattern and are covered on our office and corporate murals page.

Live painting: hours, not weeks

A live piece is designed to be finished inside the event window, whether that is a three-hour launch party or a full weekend sponsor camp. The design work still happens beforehand, so the total from brief to event is two to four weeks, but the wall itself is painted while people watch. Details are on our live painting for brands page.

How to shorten the timeline

Put one decision-maker in the first meeting and give them the authority to approve the rendering. Have the wall ready: cleared, accessible and, if it is leased, already cleared with the landlord. Start the permit the day the design is approved rather than after it. Book early; painting dates are the easy part to move, permit windows are not. And if a launch date is fixed, tell us on day one, because a schedule built backwards from a date looks different from one built forwards from a brief.

What this means for the budget

Time and cost are linked but not the same thing. A permit adds months without adding much money; fine detail adds both. Our pricing guide sets out what drives the number, and the commercial murals page explains how we schedule around a business that stays open.

Questions about mural timelines

How long does it take to paint a mural?

Two to four days of painting for a single interior feature wall, one to three weeks for a multi-area interior, and three to four weeks on the wall for a full building exterior. Add one to two weeks of design before any of that, and two to three months of permitting for an exterior inside the City of Los Angeles.

How long does a large exterior mural take?

Three to four weeks of painting for a full building elevation, after preparation. In the City of Los Angeles the registration that must come first typically adds two to three months, so plan on three to four months from brief to reveal. Outside the city it is often six to eight weeks.

How long does the design phase take?

One to two weeks, including a rendering of the artwork on a photograph of your wall and the revisions to approve it. The pace is set by how quickly decisions come back rather than by the drawing.

Can a mural be painted in one day?

Live painting can: a piece designed to be completed during an event is finished in hours. A permanent wall rarely is, because preparation, drying between layers and the protective coat each need their own time even on a small wall.

Does weather delay murals in Los Angeles?

Occasionally. Exterior paint has temperature and moisture limits, so a wet winter week or a coastal marine layer that does not lift can cost days. Interiors are unaffected.

How far ahead should we book?

For an interior, three to four weeks before you need it finished is comfortable. For an exterior inside the City of Los Angeles, three to four months, because of permitting. For a launch or event, tell us the date in the first conversation and we build the schedule backwards from it.

Does the permit really add months?

Inside the City of Los Angeles, yes: the Original Art Mural process includes a neighborhood notification window and registration steps that run in weeks, not days. Most surrounding cities are considerably lighter, and interiors need no permit anywhere. The permit guide has the details.
