Key takeaways
- California charges every impaired-driving offense as DUI. There is no DWI anywhere in the Vehicle Code.
- Four court locations list criminal work: the Central Courthouse downtown and the regional centers in Vista, El Cajon and Chula Vista.
- The City Attorney states that it prosecutes misdemeanors committed within City of San Diego limits, DUI among them. The District Attorney is organized in branches, and felonies are not on the City Attorney’s list.
- The court refers first and multiple conviction DUI cases to its Substance Abuse Assessment Unit for evaluation and referral to a DUI program.
- 10 days to ask the DMV for a hearing. The suspension itself takes effect on the 30th day after service.
- The Chula Vista courthouse states that it does not accept misdemeanor walk-in appearances.
from the date you were served with the notice to demand a hearing from California Department of Motor Vehicles. The request goes to the DMV, not to the court, and no judge in San Diego County will make it for you. Cal. Veh. Code § 13558(b).
California’s naming is simple. Every impaired-driving charge is DUI, and the base offense is Vehicle Code section 23152. What is not simple in San Diego is geography. The county’s criminal calendar runs out of four regional buildings, and the county has two prosecuting offices whose territory is drawn by the City of San Diego’s limits rather than by the county’s.
The result is a combination people do not expect: two arrests on either side of a city line, both in San Diego County and both under exactly the same statute, can be heard in different buildings and prosecuted by different offices. This page is about working out which applies to you.

The four San Diego County courthouses that hear criminal cases
All four belong to one court, the Superior Court of California, County of San Diego. The Central Courthouse serves the court’s Central Division downtown; the other three are regional centers in Vista, El Cajon and Chula Vista. Which of them holds your case decides where you go, so check the address on your paperwork against the four below.
Central Courthouse
- Hears
- Felonies and misdemeanors for the Central Division
- Building
- Central Courthouse
- Address
- 1100 Union Street, San Diego, CA 92101
- Detail
- Opened in late 2017 as a consolidated facility; the court lists criminal felonies, misdemeanors and the Substance Abuse Assessment Unit here
- Hours
- Many business-office phones answered 8:30 to 11:30am, Monday to Friday
- Phone
- 619-844-2400 (criminal: felonies, misdemeanors, SAAU)
- Why it matters
- The court states that first and multiple conviction DUI cases are referred to the Substance Abuse Assessment Unit, and the criminal line for it is the same number as for felonies and misdemeanors.
North County Regional Center
- Hears
- Criminal cases for the North County division
- Building
- North County Regional Center
- Address
- 325 South Melrose Drive, Vista, CA 92081
- Detail
- Shared with the Sheriff, Probation, the District Attorney and others
- Hours
- Many business-office phones answered 8:30 to 11:30am, Monday to Friday
- Why it matters
- Vista, not San Diego. The court describes this branch’s venue as most of northern San Diego County.
East County Regional Center
- Hears
- Criminal filings and records for the East County division
- Building
- East County Regional Center
- Address
- 250 East Main Street, El Cajon, CA 92020
- Detail
- Shared with the Sheriff, Probation, the District Attorney and others
- Hours
- Many business-office phones answered 8:30 to 11:30am, Monday to Friday
- Why it matters
- El Cajon. The DA’s East County branch sits in the same city.
South County Regional Center
- Hears
- Criminal, traffic and minor offense filings for the South County division
- Building
- South County Regional Center
- Address
- 500 Third Avenue, Chula Vista, CA 91910
- Detail
- Misdemeanor walk-in appearances are not accepted
- Hours
- Many business-office phones answered 8:30 to 11:30am, Monday to Friday
- Why it matters
- The court states that appointments may be requested at the business office counter.
The South County Regional Center states that misdemeanor walk-in appearances are not accepted and that appointments may be requested at the business office counter. If your paperwork points you to Chula Vista without a court date on it, the first visit is to get an appointment, not to appear.
The regional buildings are shared. The court describes North County, at 325 South Melrose Drive in Vista, and East County, at 250 East Main Street in El Cajon, as housing the Sheriff, Probation and the District Attorney alongside the court. South County in Chula Vista houses the court, the Sheriff and Revenue and Recovery. That is convenient on the day and confusing beforehand: the office you need may be in the same building without being behind the same counter.
Two other court buildings are easy to mix up with these. The Hall of Justice at 330 West Broadway, downtown, holds civil courtrooms and the civil and small claims business offices. Kearny Mesa, at 8950 Clairemont Mesa Boulevard, is the court’s traffic facility and hears traffic and juvenile infraction matters. The court lists its criminal work at the four buildings above.
One more practical note from the court itself: many of its business-office phones are answered only from 8:30 to 11:30 in the morning, Monday to Friday. An afternoon call to confirm a date may simply not be picked up.

The first ten days belong to the DMV
The criminal case moves on the court’s calendar. The license case moves on the DMV’s, and it is faster. After a reading at or above the limit, or a refusal, the officer serves a notice of suspension, and under Vehicle Code section 13558(b) you have 10 days from it to request a hearing. Section 13353.3(a) makes the suspension itself effective on the thirtieth day after service.
The Superior Court is explicit that this is not its business. Its DUI page tells people with license questions that they must speak to the DMV, and gives the DMV’s Mandatory Action Unit as the contact. An appearance in any of the four buildings is not a request for that hearing, and nobody at the courthouse will make one for you.
One step can start early. The court’s DUI page says a person can enroll in the DUI program through the DMV Admin Per Se procedure before the court hearing, or after it with the referral from the court and the Substance Abuse Assessment Unit. How long the program runs is set by statute, not by the court. Under Vehicle Code section 23538(b) a first offender under 0.20 attends at least 30 hours over at least three months; at 0.20 or more, or after a refusal, it is at least 60 hours over at least nine. The DUI classes guide sets that against the other five states.
| What happened | First time | With a prior | Authority |
|---|---|---|---|
| Failed the test | 4 months | 1 year | Cal. Veh. Code § 13353.3(b) |
| Refused the test | 1 year | 2 years (revocation) | Cal. Veh. Code § 23612(a)(1)(D) |
City Attorney or District Attorney
The penalty ranges are the same everywhere in California and are set out on the California DUI law page. What San Diego adds is a split in who prosecutes.
The City Attorney’s Criminal and Community Justice Division states that it prosecutes misdemeanors and infractions committed within City limits, and lists driving under the influence of alcohol or drugs among the crimes it handles. It also states that drug DUI and combined drug-and-alcohol cases go to a specialized team of deputies who handle each case vertically, through each step of the criminal process — one prosecutor for the whole case rather than a different one at each stage.
Felonies are not on the City Attorney’s list. The San Diego County District Attorney is organized by branch, and the branches’ own descriptions give a sense of scale. The North County branch serves about 1.2 million residents, a third of the county’s population. The East County branch in El Cajon serves more than 20 communities across more than 2,000 square miles. The South Bay branch in Chula Vista handles all misdemeanors and felonies in Chula Vista, National City, Imperial Beach and Coronado, among the communities it lists.
The clearest route to a felony DUI in California is a fourth offense within ten years, which section 23550 makes punishable by a state prison term. Every row of the misdemeanor ladder below that carries the same fine range, $390 to $1,000; what climbs is the jail floor and the length of the suspension.
DUI cases across San Diego County
In Dallas or Atlanta the question after an arrest is which county. In San Diego the county is the same for every row below. What changes is the division, and with it the building, and the prosecuting office.
| Situation | County | Where the case goes |
|---|---|---|
| Inside the City of San Diego | San Diego | City Attorney, for a misdemeanor — by its own description |
| Chula Vista, National City, Imperial Beach, Coronado | San Diego | District Attorney, South Bay branch in Chula Vista |
| Most of northern San Diego County | San Diego | North County Regional Center, Vista — the court’s stated venue |
| East County communities | San Diego | District Attorney, East County branch in El Cajon |
Every row in this table is the same county, the same Superior Court and the same Vehicle Code. What changes is the building and the office holding the file — and in San Diego both of those turn on where exactly the stop happened.
The table is deliberately coarse. The DA’s South Bay list also names communities, San Ysidro among them, that this page has not placed on either side of the City line, and neither office’s page resolves where its territory stops and the other’s begins. If your arrest was close to a city boundary, the charging document names the prosecuting agency, and that is the answer.
For comparison, Phoenix has the same shape of problem — city limits deciding the court inside a single county — with a municipal court in the picture as well.
Common questions about San Diego DUI cases
Which courthouse will my San Diego DUI be heard in?
It depends on where the stop happened. The Superior Court hears criminal cases at the Central Courthouse, 1100 Union Street in downtown San Diego; the North County Regional Center, 325 South Melrose Drive in Vista; the East County Regional Center, 250 East Main Street in El Cajon; and the South County Regional Center, 500 Third Avenue in Chula Vista. Check the address on your paperwork against this list.
Is a San Diego DUI prosecuted by the City Attorney or the District Attorney?
The City Attorney's Criminal and Community Justice Division states that it prosecutes misdemeanors and infractions committed within City limits, and lists driving under the influence among the crimes it handles. Felonies are not on its list. The District Attorney's South Bay branch in Chula Vista states that it handles all misdemeanors and felonies in the communities it names, and one of those, San Ysidro, is not placed on either side of the City line by this page. The charging document names the prosecuting office.
How long do I have to request a DMV hearing after a San Diego arrest?
Ten days from the date you were served with the notice, under Vehicle Code section 13558(b). The request goes to the California DMV, not to the Superior Court; the court's own DUI page directs license questions to the DMV. The suspension takes effect on the thirtieth day after service under section 13353.3(a).
What is the SAAU?
The Substance Abuse Assessment Unit of the San Diego Superior Court. The court states that first and multiple conviction DUI cases are referred to it for evaluation and referral to the appropriate DUI program, a MADD Impact Panel, and treatment where necessary. The Central Courthouse lists 619-844-2400 for criminal felonies, misdemeanors and the SAAU.
Can I enroll in a DUI program before my court date?
The court's DUI page says a person can enroll through the DMV Admin Per Se procedure before the court hearing, or after it with the referral from the court and the SAAU. The length is set by Vehicle Code section 23538(b): at least 30 hours over at least three months for a first offender under 0.20, and at least 60 hours over at least nine months at 0.20 or above or after a refusal.
Can I walk in to the Chula Vista courthouse on a misdemeanor?
No. The South County Regional Center at 500 Third Avenue states that misdemeanor walk-in appearances are not accepted, and that appointments may be requested at the business office counter.
