Septic Permits in San Luis Obispo County

County of San Luis Obispo Department of Planning & Building opens in a new tab

California has more than 1.2 million septic systems, and one statewide policy governs all of them. The State Water Resources Control Board adopted it in 2012 and amended it in April 2023. Your county, not the state, is almost always the office that issues your permit.

Every company on record in San Luis Obispo County

Ordered by verification score. The score counts records rather than workmanship, and the license line says which of three things is true: verified against the roster, checked and not found on it, or not yet checked at all.

The license check in California

California publishes a roster we can check a company against, and we have not run it against these 21 companies yet, so every license on this page currently reads as unverified. That is our backlog and not their standing.
