View shopCamper van builders in California
16 shops converting vans in California, from Encinitas to Westminster. Every listing shows the chassis they build on, what they will take on and what it costs.
Split into two distinct scenes. San Diego and Orange County are Sprinter country, with premium and performance-leaning shops; the Central Valley and Bay Area lean toward ProMaster and Transit builds at more accessible prices. The state's own emissions and registration rules are worth asking any builder about directly.

Editor's Choice in California
Three shops worth a call, picked for different reasons. Editorial choices, and placement here is not for sale.

Building since 1961, and one of very few shops that will still take on an older Ford E-Series.

Westminster, CA

Best for Compact city builds

Common questions
How many camper van builders are there in California?
We list 16 conversion companies in California, spread across 14 towns and cities. That is the set we have researched and can stand behind rather than every business that has ever converted a van. If you know a California shop that should be here, send it to us.
What does a conversion cost in California?
Published build costs among the California shops listed here run from about $18k to $115k. Those figures are almost always for the conversion alone, so budget another $45k–$70k for the van itself unless the builder sources it for you.
Do I have to use a builder in California?
No, and plenty of people do not. A build involves two or three visits over several months, so buyers routinely cross state lines for the right shop. Where local matters is afterwards: warranty work, servicing and the awkward fault two years in are all much easier when the builder is a day's drive away rather than three.
What should I ask on a first call?
What the quoted price includes and excludes. Whether the queue in front of you is weeks or months. Who does warranty work and for how long. Whether they will service a van they did not build. And what happens to your deposit if you walk away. The answer varies far more than it should.
Builders in other states
Worth widening the search, because the shop you want may be two states over, and for a build of this length that matters less than it sounds.
