Methodology

The free grade on this page contains zero zReports judgment: it maps the state's own published licensing and enforcement verdicts through one fixed rule, applied identically to every treatment center in America. Where the record and public reputation diverge, a highly reviewed facility with serious findings on file, the paid Consumer Intelligence Report™ surfaces it through the composite Consumer Z Score™ and our published ten point methodology. Facilities are never contacted and cannot pay to change a score. Read the full methodology →

About treatment center licensing in California

Addiction Treatment Centers in California are overseen by the state's licensing authority, whose certification, inspection, and quality-reporting data is published on the public record. This page is computed from SAMHSA FindTreatment.gov federal locator of state-licensed treatment facilities (BHSIS), the government’s own filings, not reviews or advertising.

Frequently asked questions

How many treatment centers are there in California?

California has 1,415 active licensed treatment centers on the state's public file, across 345 cities. Every one has a free records layer grade on zReports.

Which California city has the most treatment centers?

Los Angeles, with 96 licensed treatment centers, followed by San Diego (55) and Sacramento (32).

How are California treatment center grades calculated?

The free records layer grade contains zero zReports judgment. It maps the government's own published verdicts, SAMHSA FindTreatment.gov federal locator of state-licensed treatment facilities (BHSIS), through one fixed rule, applied identically to every treatment center in the country. The paid Consumer Intelligence Report™ adds the composite Consumer Z Score™, which audits the record against public reputation through our published ten point methodology.

Why can a facility with 5-star reviews have a low grade?

Reviews and records are different surfaces. Reviews reflect what visitors chose to write, and can be managed by the business. Inspection and enforcement records are filed by the state, are mandatory, and cannot be edited by the facility. When the two diverge, the record is the surface worth checking. That divergence is exactly what zReports was built to surface.

How often are these rankings updated?

Rankings refresh whenever California republishes its licensing data; facility pages carry the records-verified date for each provider. This page was generated from the current file as of September 2026.

Can a facility pay to change its score?

No. Facilities are never contacted, never notified, and cannot pay to be listed, delisted, or re-scored. zReports has no business relationship with any facility it grades, independence is the product.
