How DUIs are policed in Del Mar
Del Mar has never operated its own police department. The city — one of the smallest and least populous in San Diego County, with a 2020 Census population of just 3,954 (down from 4,161 in 2010) packed into roughly two square miles — has contracted with the San Diego County Sheriff's Department for police services since it incorporated on July 15, 1959. Patrol is run out of the Sheriff's North Coastal Station, 175 North El Camino Real, Encinitas, the same station that covers neighboring Encinitas and Solana Beach. Inside Del Mar's own small footprint, deputies patrol Camino Del Mar (the old U.S. Highway 101 alignment that still runs through the Del Mar Village shopping district), Jimmy Durante Boulevard along the fairgrounds, and the Via de la Valle interchange with Interstate 5.
The Del Mar Fairgrounds — the state-owned property that hosts both the Del Mar Racetrack and the annual San Diego County Fair — is policed under a separate arrangement: the Sheriff's Department contracts directly with the 22nd District Agricultural Association, the state entity that operates the fairgrounds on California's behalf, to staff deputies specifically for events on the grounds. That distinction matters for DUI exposure, because Del Mar's two biggest draws for drinking crowds — the summer racing meet and the County Fair — are both concentrated into a short seasonal window on fairgrounds property, policed under that fairgrounds-specific contract, while the rest of the city's streets fall under the Sheriff's regular municipal patrol contract.
- Del Mar incorporated July 15, 1959, and has relied on San Diego County Sheriff's deputies for police service ever since — the city has never run its own department.
- Patrol is based out of the Sheriff's North Coastal Station in Encinitas, which also covers Encinitas and Solana Beach.
- The Del Mar Fairgrounds (racetrack and County Fair grounds) is policed separately, under the Sheriff's distinct contract with the state-run 22nd District Agricultural Association.
- At roughly 3,954 residents (2020 Census), Del Mar is regularly counted among San Diego County's least-populated incorporated cities.
Where a Del Mar DUI case is heard — and the ZIP code trap
Here is the one thing about a Del Mar DUI that trips people up if they research it themselves: Del Mar's ZIP code, 92014, is listed as Central on the San Diego Superior Court's general-purpose ADM-254 ZIP Code List — the table most people find first when they look up which courthouse handles their ZIP. But San Diego Superior Court Local Rule 1.2.2(H)(2) specifically carves criminal cases arising in Del Mar out of that general assignment and sends them to the North County Division instead. For a DUI specifically — a criminal matter — the Local Rule controls, not the ZIP table. That means a Del Mar DUI arrest is heard at the North County Regional Center, 325 South Melrose Drive, Vista, CA 92081 — the same courthouse that hears cases from Encinitas, Solana Beach, Carlsbad, Oceanside, Escondido, San Marcos, Vista, and Fallbrook — not the Central Courthouse in downtown San Diego that a ZIP-code search alone would point to.
Worth flagging for context: ZIP code 92014 covers a wider area than the tiny incorporated city itself (roughly 13,000 residents in ZIP-level estimates versus Del Mar's own population of under 4,000), since the ZIP boundary extends beyond Del Mar's city limits into neighboring unincorporated and city-of-San-Diego territory. That gap between "the ZIP code" and "the actual city" is part of why the general ZIP table and the Local Rule's city-specific carve-out can point in different directions. There is no city prosecutor in Del Mar — the San Diego County District Attorney's North County branch prosecutes every Del Mar DUI, the same office that handles the rest of the North County Division's caseload, whether the charge is a misdemeanor or a felony.
Del Mar DUI — court & DMV details
Booking and getting a car back after a Del Mar arrest
A DUI arrest anywhere in Del Mar is booked at the Vista Detention Facility, 325 South Melrose Drive, Vista — the same North County campus as the courthouse itself, and the facility the Sheriff's Department uses to book both men and women arrested anywhere in North County. From there, release depends on the specifics of the stop: citation, bail, or an initial court appearance. Family members trying to locate someone booked out of a Del Mar arrest can call our office for help, or contact the facility directly.
Your vehicle is a separate issue from your custody status. A routine DUI tow under Vehicle Code §22651(h) generally lets you, or someone you authorize, retrieve the car from the tow yard once the release paperwork and fees are handled. A mandatory 30-day impound under Vehicle Code §14602.6 is different and more serious — it applies only when the driver was also unlicensed, suspended, revoked, or driving on a restricted license without a required interlock device, not to a routine DUI arrest by itself. Ask us which situation applies to your stop during your free consultation.
A beach resort, a racetrack, and the smallest big name on the coast
Del Mar was founded in 1885 as a seaside resort and didn't incorporate as its own city until July 15, 1959 — a deliberate move by residents to keep local control over a small coastal community rather than be absorbed into San Diego's growth from the south. More than six decades later, Del Mar is still one of San Diego County's smallest cities by both land area and population, periodically cited in local reporting as the county's least-populated incorporated city — a status that belies how widely recognized its name is, almost entirely because of what sits at its southern edge: the Del Mar Fairgrounds.
La Jolla developer William A. Quigley pitched a Santa Anita-style racetrack for the fairgrounds property to Bing Crosby in the mid-1930s, and the two formed the Del Mar Turf Club on May 6, 1936, raising roughly $2 million from mostly Hollywood investors — Crosby and actor Pat O'Brien among them — to build the Spanish Mission-style grandstand, clubhouse, and track, with a Depression-era Works Progress Administration grant helping fund construction. The Del Mar Racetrack opened July 3, 1937, with Crosby greeting the first fan through the gate, and the track's unofficial anthem, "Where the Turf Meets the Surf" (which Crosby co-wrote and performed), is still played on race days. Its most famous moment came on August 12, 1938, when Seabiscuit beat Ligaroti in a $25,000 winner-take-all match race broadcast nationally by NBC radio — one of the signature events in American horse-racing history. The same fairgrounds property hosts the San Diego County Fair each summer, drawing crowds on a scale the tiny city's own population figures don't begin to suggest.
