The California Field Act is the state law that requires every public K–12 school and community college construction project to meet seismic safety standards enforced by the Division of the State Architect (DSA). The Legislature passed it in 1933, barely a month after the magnitude 6.4 Long Beach earthquake destroyed numerous unreinforced masonry school buildings and exposed how vulnerable children were inside them.1U.S. Geological Survey.

What Buildings the Field Act Covers
Education Code Section 17281 applies the Act to K–12 school districts and community college districts.3California Legislative Information. California Education Code EDC 17281 Any permanent structure where students gather for instruction, along with support facilities like gymnasiums and cafeterias, must comply. New construction, additions, and major alterations to existing buildings all trigger the Act’s requirements.
Portable classrooms are not exempt. Plans must be submitted to DSA each time a relocatable building is moved to a new site, and manufacturers must attach permanent metal identification labels on each module showing the DSA application number, building code edition, design live loads, and seismic design parameters.4Division of the State Architect.

Schools Outside the Field Act
Charter schools are generally exempt. They must meet the California Building Standards Code as enforced by the local building authority, though a charter that voluntarily complies with the Field Act is then exempt from the local code. Private schools were outside the Act entirely until 1986; those built or altered after that year must meet similar seismic safety requirements enforced by local governments rather than DSA.5California Seismic Safety Commission. The Future of the Field Act for Public Schools The University of California and California State University systems operate under their own construction oversight and are not governed by the Field Act.
What the Law Requires of a Project
Licensed Design
Plans must be prepared and signed by a California-licensed architect or structural engineer. The original Act was prompted by findings that loose subsoil, shoddy workmanship, and substandard materials all contributed to the collapse of school buildings in 1933, and the design standards still reflect that history.2California Geological Survey. The 1933 Long Beach Earthquake Designers must account for lateral force resistance so the structure can absorb seismic shaking without collapsing, and site-specific geological hazards factor into foundation plans. Materials like reinforced concrete and structural steel must meet specific strength and flexibility requirements.
The performance goal is not necessarily zero damage. It is that the building stays standing long enough for occupants to evacuate safely. That bar is higher than the standard California Building Code sets for ordinary structures, because the occupants are primarily children who depend on adults to guide them out.
DSA Plan Review
Before a district can award a construction contract or break ground, comprehensive plans must go to DSA. The submission includes detailed blueprints, structural calculations proving the building can handle predicted seismic loads, and technical specifications for materials and systems. DSA structural engineers evaluate the documents against the standards in the Education Code.2California Geological Survey. The 1933 Long Beach Earthquake
Written DSA approval is a hard prerequisite. No construction can legally begin without it, and a project that proceeds without approval is unauthorized and exposes the district to serious liability. Review timelines depend on DSA workload and code transition cycles, and districts that submit near a code change can face delays of several weeks.6Division of the State Architect.

On-Site Inspection
Every project under DSA jurisdiction must have a certified project inspector on site.7Division of the State Architect. Project Inspector Certification That person verifies that each phase of construction matches the approved plans, from rebar placement to the concrete mix, and reports to both the school board and DSA.8Division of the State Architect. DSA PR 13-01 Construction Oversight Process The architect or structural engineer in charge provides periodic general observation, and any work that doesn’t conform to the approved documents must be corrected immediately. Daily logs and inspection records create a paper trail documenting every step of the build.
Verified Reports and Certification
When construction wraps up, four separate parties must each file a verified report with DSA: the architect or engineer, every prime contractor, and the project inspector. Each report affirms on a designated DSA form that the work was completed in conformance with the approved construction documents.8Division of the State Architect. DSA PR 13-01 Construction Oversight Process
Once DSA reviews the verified reports and confirms compliance, the state issues a project certification. That certification is the official confirmation that the building meets Field Act standards. Using a school building before certification is issued exposes the district to legal liability and can jeopardize state funding and insurance coverage for the facility.
What Happens If a District Doesn’t Comply
Compliance also provides a legal shield. Under Government Code Section 830.6, a school building approved and constructed under the Field Act carries design immunity, which protects the district and its board members against lawsuits for injuries caused by the structure’s design. That immunity disappears once the district knows or has reason to know about an unsafe condition, whether through a report from an architect, a structural engineer, or DSA itself.
When immunity is lost, the consequences get personal. Board members can face liability if they fail to act after learning of a dangerous condition. Attorney General opinions have concluded that punitive damages could be sought against board members who have knowledge of a hazard and a statutory duty to act but choose to do nothing. Even a board member who votes to fix the problem but is outvoted may not escape personal liability if the repairs never happen.
A board facing a known unsafe condition has limited options: fund the repairs, seek funding and post warning signs that the building is unsafe, or abandon the building entirely. Continuing to use a structure flagged as unsafe is the one option the law does not permit. Districts do receive some protection through statutory indemnity under Government Code Section 825, which requires the district to cover a board member who acted in good faith and without malice, but that indemnity has limits and does not extend to willful disregard of known dangers.
Why Compliance Matters in Practice
No school building constructed under the Field Act has suffered a catastrophic collapse in a California earthquake since 1933. The record exists because the law creates an unbroken chain of accountability: a licensed professional designs the building, DSA approves the plans, a certified inspector watches every phase of construction, and multiple parties stake their professional reputations on verified reports before a district takes occupancy. Each link depends on the others.
For a district, Field Act compliance determines whether it has legal protection if something goes wrong, whether it qualifies for state construction funding, and whether it can insure the building at reasonable rates. Cutting corners on any step saves time in the short run and creates exposure that can outlast the building itself.
