Towns in Contra Costa County

About this data

Where the list comes from and what it does and does not say
173in the directory
173license unexpired
23cities
11ymedian years licensed
10thby size in this category

The largest concentration is in Concord: 36 of 173 (21%). Other cities covered include Richmond (21), Walnut Creek (21), Antioch (16), Brentwood (9), Pittsburg (9), and 17 more.

Of the 173 entries here whose register publishes license dates, 173 have a license that has not expired. That split is computed from the expiry date each register publishes, rather than taken from any status the register may print.

Across the 173 entries with a recorded first-issue date, the median has held a license for 11 years. The longest-standing is Lehmers Concord Buick Gmc, first licensed in January 1972, 54 years ago.

The license classes represented here are Smog Station - Test & Repair (106), Smog Station - Test Only (61), Vehicle Safety Systems Inspection Station (4), Smog Station - Repair Only (2). The class is the source's own wording, not a label applied here.

This list publishes no phone numbers, so no listing drawn from it shows one. That is how the source publishes it, not a gap in this record.

The map positions were derived from the published street address through the US Census Bureau geocoder. No distance claim is made anywhere in this text; the "nearest to me" list computes straight-line distances in your own browser from your own location.

10 of the 173 entries could not be placed on a map: the register gives a PO box, a bare route number or a road junction rather than a street address, and 10 of those are currently on the register. They are listed and searchable here by name, city and county, and left out of the map and the "nearest to me" results. Guessing a plausible position for a PO box would be worse than admitting there is not one.

Contra Costa County ranks 10th of the 41 counties covered in this category, holding 3% of the listings, ahead of 31 others.

For a wider choice, the largest counties in this category are Los Angeles County (1338), San Diego County (545), Orange County (452), San Bernardino County (385). They are ordered by how many entries each holds, not by how close they are.

Every record on this page comes from Public licensee list (Automotive Repair), published by California Bureau of Automotive Repair on dca.ca.gov as dataset AutomotiveRepair_1310. Each card carries the date the record was last re-checked.

What the rules require

Contra Costa County: questions

Which cities in Contra Costa County have stations?
By count: Concord (36), Richmond (21), Walnut Creek (21), Antioch (16), Brentwood (9), Pittsburg (9), San Ramon (9), El Cerrito (8), San Pablo (7), Martinez (6), plus 13 more. Addresses, license class and, where the register publishes them, license dates are in the list above.
How many of these stations are still licensed?
173 of the 173 whose register publishes dates hold a license that has not expired. The official register lists live and lapsed records together; the split here is computed from the expiry date it publishes.
How long have they held their licenses?
Across the 173 with a recorded first-issue date the median is 11 years, and the longest is 54 years: Lehmers Concord Buick Gmc, first licensed in January 1972.
Why do the cards not show star ratings?
No public rating has been matched to any of these 173 records, so no stars are shown. The license record is the stronger signal in any case: where the register publishes them, the issue date, last renewal, expiry and the state license number all come from the issuing authority, which is not true of a star average.
Why are some entries missing from the map?
10 of these 173 records give a PO box, a bare route number or a road junction instead of a street address, so no coordinate could be derived for them. They are still listed and searchable by name, city and county, and they are left out of the map and the "nearest to me" results. Placing a PO box at a plausible-looking point would make the map look complete and be wrong.

A listing closed, moved or missing? It gets checked against the source

Something wrong on this page?

These records come from state registers and the registers are not perfect. If a listing is closed, has moved, or the license details do not match what the state told you, say so and it gets checked against the source.
