How DUIs are policed in San Marino

San Marino is one of the few cities in the San Gabriel Valley that has never contracted out its policing. The San Marino Police Department is a full, independent municipal agency headquartered inside City Hall at 2200 Huntington Drive, San Marino, CA 91108 — non-emergency line (626) 300-0720 — with roughly two dozen sworn officers covering the city's 24-hour patrol shifts. Unlike a Sheriff's contract city, there's no separate sub-station to look for: City Hall is the department. A DUI stop inside San Marino's own 3.8 square miles — on Huntington Drive, Lake Avenue, Los Robles Avenue, Sierra Madre Boulevard, or any of the smaller residential streets making up the rest of the city — is made by a San Marino PD officer, not a county deputy or the CHP.

That changes the instant a stop happens outside city limits. San Marino has no freeway inside its own borders — the city is boxed in by Pasadena to the north and east, South Pasadena to the west, and Alhambra and San Gabriel to the south, and none of the region's freeways physically cross into it. The nearest segments are the I-210 (Foothill Freeway), roughly 1.5 miles north through Pasadena, and the long-stalled, unbuilt "gap" in I-710 between Alhambra and Pasadena — a project San Marino's own city council has weighed in on for decades. Freeway-adjacent stops on the I-210 are typically handled by the CHP's Altadena Area office, 2130 Windsor Avenue, Altadena — the same office this site's Altadena and Duarte pages cite for that freeway — but because no freeway actually runs through San Marino itself, the overwhelming majority of DUI stops here are made by San Marino PD on city streets.

• San Marino has operated its own police department continuously since at least 1913 (one city account dates the first appointed marshal to that year; a separate account places the first formal police chief appointment in 1924) — it has never been a Sheriff's contract city.
• At only 3.8 square miles, San Marino is small enough that its entire street grid falls under one department's jurisdiction, with no freeway segment inside city limits to divide enforcement with the CHP.

Where a San Marino DUI case is heard — an honest answer, not a guess

Most DUI-lawyer directory sites simply list San Marino alongside Alhambra, Monterey Park, San Gabriel, and Temple City as a city whose cases go to the Alhambra Courthouse, 150 W. Commonwealth Ave., Alhambra, CA 91801. We can't responsibly repeat that as settled fact. When we pulled the Alhambra Courthouse's own jurisdiction record directly from the Los Angeles County court locator while building this site's Alhambra Courthouse page, it named exactly four cities — Alhambra, Monterey Park, San Gabriel, and Temple City — and did not name San Marino. An earlier draft of that same Alhambra Courthouse page on this site did include San Marino (along with Monrovia and South Pasadena), based on a secondhand, AI-summarized source; that claim was removed after we went back to the court's own record and couldn't confirm it.

So here's where that leaves this page: San Marino's DUI cases are commonly associated with the Alhambra Courthouse in casual directory listings, but the courthouse's own official jurisdiction record doesn't name San Marino directly, and we already pulled that claim off this site once after it didn't hold up. We are not going to present Alhambra as a confident default for San Marino. If you've been cited or arrested, the fastest way to know for certain is the courthouse name printed right on your citation or arrest paperwork, or a call to the court clerk's office — and that's exactly what Ron does first on every San Marino case before filing anything.

Booking and getting a car back after a San Marino arrest

A DUI arrest in San Marino is booked first at San Marino PD, inside City Hall at 2200 Huntington Drive — that's an intake stop, not a long-term holding facility for a small department like this one. From there, an arrestee is typically transferred into the Los Angeles County jail system: men generally end up at the Inmate Reception Center, Men's Central Jail, or Twin Towers downtown, and women at the Century Regional Detention Facility in Lynwood. Release conditions — own recognizance, bail, or cite-and-release — depend on the specifics of the stop. If you're trying to track down a family member arrested in San Marino, call our office and we'll help you find them faster than guessing at which downtown facility they landed in.

Your vehicle is handled separately from your arrest. A standard post-DUI tow lets you or someone you authorize retrieve the car from the tow yard once the release paperwork, towing fee, and storage fee are squared away. A mandatory 30-day impound under Vehicle Code §14602.6 is a different, narrower rule — it only applies when the driver was also on a suspended or revoked license, on a restricted license without a required interlock device, or had never been issued a license at all. It is not an automatic consequence of a DUI stop by itself. Ask Ron to check which rule actually applies to your stop during your free consultation.

The Huntington, Lacy Park, and a city built to stay independent

San Marino's defining landmark needs little introduction: the Huntington Library, Art Museum, and Botanical Gardens, the 120-acre former estate of railroad magnate Henry E. Huntington, who assembled the land in 1903 and incorporated the city of San Marino in 1913 largely to protect it — reportedly to head off annexation by neighboring Pasadena and to lock in strict zoning rather than leave the area's future to a bigger city's council. Huntington's estate, deeded to the public, now holds one of the world's great rare-book and manuscript collections (including a Gutenberg Bible), major American and British art, and botanical gardens that draw visitors well beyond Southern California. The city's own name traces back further still, to "San Marino," the name James De Barth Shorb (son-in-law of early landowner Benjamin Wilson) gave his own estate on part of the same ground decades earlier.

Two blocks of that history are easy to miss if you're only passing through on Huntington Drive. El Molino Viejo — "The Old Mill" — was built around 1816 by Mission San Gabriel to grind grain, and is generally regarded as the oldest commercial building still standing in Southern California; the Huntington family bought the surrounding land in 1903, and the city itself has owned the mill since it was gifted to San Marino in 1962. Next door, Lacy Park — roughly 30 acres built on a drained lake bed in the mid-1920s and named for an early San Marino mayor — is the city's main public green space. San Marino is also one of the most academically distinctive small cities in the county: San Marino High School has ranked among the top tier of U.S. public high schools in independent rankings in recent years, and ACS data for 2019–2023 puts roughly 80% of adult residents at a bachelor's degree or higher — figures that go hand in hand with a largely residential, low-density city of about 12,500 people where the median household income tops $180,000. None of that changes how DUI law applies here, but it's part of why an out-of-town cite can feel disorienting if you've never had a reason to deal with San Marino PD or the courts before.
