Special Construction, Hazards & Equipment

Chapter 31 of the CRC groups rules for nonstandard building features and hazardous equipment — read §3101 and the listed sections for scope and specific requirements.

Last reviewed: July 6, 2026

Overview

This part of the California Residential Code (CRC) collects rules for atypical structures, special building elements, hazardous equipment and systems, and the safety features that accompany them. It covers membrane and temporary structures, pedestrian walkways and tunnels, awnings/canopies, automatic vehicular gates, solar energy systems, greenhouses, relocatable buildings and other unique elements that don’t fit ordinary dwelling chapters. See the chapter scope at §3101 for the catalogue of special construction topics covered.

The rules matter because these features introduce distinct structural, fire, access and life‑safety risks (for example, swimming pool barriers and equipment, rooftop PV load and attachment, and automatic gate entrapment hazards). Practical entry points in the code include the temporary‑structure and permit requirements at §3103, pool and spa safeguards at §3109, automatic vehicular gate standards at §3110, and rooftop solar requirements at §3111. Consult the chapter index in the CRC for how these sections map into residential enforcement.

    2. Addition of new structural components or systems at an existing MOT that are structurally independent of existing components or systems.

    3. Addition of new (nonreplacement) equipment, piping, pipelines, components or systems to an existing MOT.

    4. Major repairs or substantially modified in-place systems.

    5. Any associated major installations or modifications.

    3101F.4 Overview. This Code ensures that a MOT can be safely operated within its inherent structural and equipment-related constraints.

    Section 3102F defines minimum requirements for audit, inspection and evaluation of the structural, electrical and mechanical systems on a prescribed periodic basis, or following a significant, potentially damage-causing event.

    Section 3103F, 3104F and 3107F provide criteria for structural loading, deformation and performance-based evaluation considering earthquake, wind, wave, current, seiche and tsunami effects.

    Section 3105F provides requirements for the safe mooring and berthing of tank vessels and barges.

    Section 3106F describes requirements for geotechnical hazards and foundation analyses, including consideration of slope stability and soil failure.

    Section 3108F provides requirements for fire prevention, detection and suppression including appropriate water and foam volumes.

    Sections 3109F through 3111F provide requirements for piping/ pipelines, mechanical and electrical equipment and electrical systems.

    Section 3112F provides requirements specific to marine terminals that transfer LNG.

    Generally, English units are typically prescribed herein; however, System International (SI) units are utilized in Section 3112F and in many of the references.

    3101F.5 Spill prevention. Each MOT shall utilize up-to-date Risk and Hazards Analysis results developed per CCPS “Guidelines for Hazard Evaluation Procedures” [1.1] and [1.2], to identify the hazards associated with operations at the MOT, including operator error, the use of the facility by various types of vessels (e.g., multi-use transfer operations), equipment failure and external events likely to cause an oil spill.

    5 SPECIAL BUILDING CONSTRUCTION REGULATIONS

    User notes:

    About this chapter: Chapter 5 provides regulations that establish minimum standards for the location, design and construction of buildings and structures based on construction within a Fire Hazard Severity Zone or a Wildland-Urban Interface (WUI) Area.

    The construction provisions of Chapter 5 are intended to supplement the requirements of the California Building Code and California Residential Code and address mitigation of the unique hazards posed to buildings by wildfire and to reduce the hazards of building fires spreading to wildland fuels. This is accomplished by requiring ignition-resistant construction materials. Construction features regulated include underfloor areas; roof coverings; eaves and soffits; gutters and downspouts; exterior walls, doors and windows; ventilation openings and accessory structures.

    SECTION 501—GENERAL

    501.1 Scope. Buildings and structures in a wildland-urban interface area shall be constructed in accordance with the California Build- ing Code and this code.

    Exceptions:

    1. Group U accessory structures not exceeding 120 square feet (11 m [2] ) in floor area where located not less than 50 feet (15 240 mm) from applicable buildings.
