Seismic, Wind, Nonstructural Seismic Certification, Fire & Smoke Testing

The CBC centralizes requirements for inspection, testing and certification of seismic, wind, nonstructural and fire/smoke systems—see §§1613, 1609, 1704–1705 for scope, testing paths and submittals.

Last reviewed: July 5, 2026

Overview

This area of the California Building Code (CBC) covers special inspections, testing and certification required to verify performance of seismic and wind force‑resisting systems, nonstructural components, and fire- and smoke‑related materials and assemblies. The CBC assigns responsibilities for the statement of special inspections, required submittals and contractor statements, and establishes when nondestructive, prototype or production testing is required to demonstrate compliance. See the rules for statements of special inspections and required submittals in §1704 and the special inspections/testing provisions in §1705.

Seismic provisions specify design and assignment to Seismic Design Categories and apply earthquake load rules for both structure and attached nonstructural components (see §1613) while wind provisions and wind‑resisting inspection requirements reference Chapter 16/§1609 and the special inspection details in §1705. §1613 sets seismic design scope and category rules; §1609 and §1705 identify wind load and inspection requirements respectively.

Nonstructural seismic certification and special seismic certification (including shake‑table and other testing, manufacturer’s certification and certificates of compliance) are prescribed in the §1705.14 series, with specific testing and certification paths, deemed‑to‑comply options, and documentation/submittal requirements spelled out in §1705.14, §1705.14.2 and §1705.14.3. Fire and smoke testing and inspection requirements (for example sprayed fire‑resistive materials and smoke/heat vent criteria) are covered in the related special inspection paragraphs such as §1705.15 and referenced fire code sections.

    Exception: If the anchorage or bracing is configured in a manner that results in significant torsion on a supporting structural element, the effects of the nonstructural reaction force on the structural element shall be considered in the anchorage design.

    501 A . 4 Health care facilities. In Group I-2 facilities, ambulatory care facilities and outpatient clinics, any altered or added portion of an existing electrical or medical gas systems shall be required to meet installation and equipment requirements in NFPA 99.

    SECTION 502 A —ADDITIONS

    502 A .1 General. Additions to any building or structure shall comply with the requirements of the California Building Code for new construction. Alterations to the existing building or structure shall be made to ensure that the existing building or structure together with the addition are not less complying with the provisions of the California Building Code than the existing building or structure was prior to the addition. An existing building together with its additions shall comply with the height and area provisions of Chapter 5 of the California Building Code . Where a new occupiable roof is added to a building or structure, the occupiable roof shall comply with the provisions of the California Building Code.

    Exception: In-filling of floor openings and nonoccupiable appendages such as elevator and exit stairway shafts shall be permitted beyond that permitted by the California Building Code.

    502 A .1.1 Risk category assignment. Where the addition and the existing building have different occupancies, the risk category of each existing and added occupancy shall be determined in accordance with Section 1604 A .5.1 of the California Building Code . Where application of that section results in a higher risk category for the existing building compared with the risk category for the existing building before the addition, such a change shall be considered a change of occupancy and shall comply with Section 506 A of this code. Where application of that section results in a higher risk category for the addition compared with the risk category for the addition by itself, the addition and any systems in the existing building required to serve the addition shall comply with the requirements of the California Building Code for new construction for the higher risk category.

    502 A .1.2 Creation or extension of nonconformity. An addition shall not create or extend any nonconformity in the existing building to which the addition is being made with regard to accessibility, structural strength, supports and attachments for nonstructural components, fire safety, means of egress or the capacity of mechanical, plumbing or electrical systems.

Frequently asked questions

When does the CBC require nonstructural seismic certification?

Nonstructural seismic qualification/certification is required for components in applicable Seismic Design Categories (B–F) when ASCE 7 nonstructural provisions apply; the registered design professional must specify analysis, testing or experience data and submit certificates of compliance per §1705.14.2 and related submittal rules in §1704.5.

What sections govern special inspections and testing for seismic and wind resistance?

Special inspections and tests are governed primarily by §1704 (statement of special inspections, submittals and contractor responsibilities) and §1705 (required special inspections and tests, including §1705.12–§1705.14 for wind and seismic). See §1609 for wind loads and §1613 for earthquake load scope and seismic design category assignments.

Where are fire‑ and smoke‑related tests and inspections found?

Testing and special inspections for fire‑resistive materials (e.g., SFRM) and smoke/heat venting are specified in the §1705 series (for special inspections and sampling) and in the fire‑related CBC/Fire Code sections cited (for sprinklers, smoke control and vents); see §1705.15 for SFRM and the referenced acceptance criteria and vent standards.
