Smog check rules and DMV offices for Napa
California asks for a smog check at every other registration renewal once a gas or hybrid car is more than eight model years old. Diesels have no age exemption.
Selling a car older than four model years needs a certificate under 90 days old, and a car moving here from another state needs one to register.
Your DMV renewal notice is the final word for an address in Napa. It says whether this year's renewal needs a check and whether it has to be at a STAR station.

- How much is a smog check in Napa?
- Each station sets its own price, and it varies by vehicle, so call ahead. Every station adds the $8.25 state certificate.
