California Project Inspector & IOR

Application Process Guide

Introduction

This guide provides a comprehensive overview of the application processes for becoming a certified Inspector of Record (IOR) or Project Inspector in California. There are two primary certification bodies: the Division of the State Architect (DSA) for educational facilities and HCAI (Department of Health Care Access and Information) for healthcare facilities. Understanding the requirements, pathways, and documentation needed for each will help you navigate the certification process successfully.

The DSA certifies Project Inspectors for K-12 public schools, community colleges, state-owned facilities, and essential services buildings. The application is Form DSA 175.

Understanding DSA Inspector Classes

Class 1 — Highest Level

Qualifies for the most complex projects including new buildings of Type I or II construction (steel, concrete). Required for large schools and complex structural work.

Class 2 — Broad Range

Qualifies for buildings of Type I, II, III, or IV construction. Covers most school projects except the most complex ones.

Class 3 — Entry Level

For smaller, less complex projects. Often serves as stepping stone to higher classes. Wood-frame construction and smaller additions.

Note: A Class 4 certification also exists as a pathway into Class 3.
