Scope & applicability of CALGreen Chapter 3

CALGreen Chapter 3 sets the scoping rules that determine when and where mandatory and voluntary green‑building measures apply.

Last reviewed: July 6, 2026

Overview

Chapter 3 of the California Green Building Standards Code (CALGreen) is the scoping chapter for green‑building requirements: it declares which projects must include the mandatory green measures, how voluntary measures and tiers work, and how the rules apply to different building types and work types. The chapter begins with a statement of scope in §301.1 and a table of contents identifying the chapter’s parts (General, Mixed Occupancy, Phased Projects, Voluntary Tiers, and CALGreen Tier descriptions) .

The chapter also explains common applicability rules that affect everyday design decisions: application to additions and alterations (§301.1.1), distinctions for low‑rise vs. high‑rise residential provisions (§301.2), and thresholds that limit when nonresidential additions/alterations apply (§301.3). Mixed‑occupancy scoping (§302.1), rules for phased/shell projects (§303.1), and the voluntary tier structure (§304.1 and §305.1) are all set out so designers and enforcing agencies can determine which mandatory measures and checklists must be used on a given permit or phase .

    3 GREEN BUILDING

    SECTION 301—GENERAL

    301.1 Scope. Buildings shall be designed to include the green building measures specified as mandatory in the application checklists contained in this code. Voluntary green building measures are also included in the application checklists and may be included in the design and construction of structures covered by this code, but are not required unless adopted by a city, county, or city and county as specified in Section 101.7.

    301.1.1 Additions and alterations. [HCD] The mandatory provisions of Chapter 4 shall be applied to additions or alterations of existing residential buildings where the addition or alteration increases the building’s conditioned area, volume or size. The requirements shall apply only to and/or within the specific area of the addition or alteration.

    The mandatory provisions of Section 4.106.4.2 may apply to additions or alterations of existing parking facilities or the addition of new parking facilities serving existing multifamily buildings. See Section 4.106.4.3 for application.

    Note: Repairs including, but not limited to, resurfacing, restriping, and repairing or maintaining existing lighting fixtures are not considered alterations for the purpose of this section.

    301.2 Low-rise and high-rise residential buildings. [HCD] The provisions of individual sections of CALGreen may apply to either low-rise residential buildings, high-rise residential buildings, or both. Individual sections will be designated by banners to indicate where the section applies specifically to low-rise only (LR) or high-rise only (HR). When the section applies to both low-rise and highrise buildings, no banner will be used.

    301.3 Nonresidential additions and alterations. [BSC-CG] The provisions of individual sections of Chapter 5 apply to newly constructed buildings, building additions of 1,000 square feet or greater, and/or building alterations with a permit valuation of $200,000 or above (for occupancies within the authority of California Building Standards Commission). Code sections relevant to additions and alterations shall only apply to the portions of the building being added or altered within the scope of the permitted work.

    A code section will be designated by a banner to indicate where the code section only applies to newly constructed buildings [N] or to additions and/or alterations [A] . When the code section applies to both, no banner will be used.

    301.5 Health Facilities. [OSHPD 1, 2 & 4] Health facilities under the jurisdiction of the Office of Statewide Health Planning and Development (OSHPD) are required to comply with the mandatory measures prescribed in Section 5.304, Outdoor Water Use.

    GREEN BUILDING

    SECTION 302—MIXED OCCUPANCY BUILDINGS

    302.1 Mixed occupancy buildings. In mixed occupancy buildings, each portion of a building shall comply with the specific green building measures applicable to each specific occupancy.

    Exceptions:

    1. [HCD] Accessory structures and accessory occupancies serving residential buildings shall comply with Chapter 4 and Appendix A4, as applicable.
    2. [HCD] For the purposes of CALGreen, live/work units, complying with Section 508.5 of the California Building Code, shall not be considered mixed occupancies. Live/work units shall comply with Chapter 4 and Appendix A4, as applicable.

    SECTION 303—PHASED PROJECTS

    303.1 Phased projects. For shell buildings and others constructed for future tenant improvements, only those code measures relevant to the building components and systems considered to be new construction (or newly constructed) shall apply.

    303.1.1 Initial tenant improvements. The provisions of this code shall apply only to the initial tenant improvements to a project. Subsequent tenant improvements shall comply with the scoping provisions in Section 301.3 nonresidential additions and alterations.

    SECTION 304—VOLUNTARY TIERS

    304.1 Purpose. Voluntary tiers are intended to further encourage building practices that improve public health, safety and general welfare by promoting the use of building concepts which minimize the building’s impact on the environment and promote a more sustainable design.

    304.1.1 Tiers. The provisions of Divisions A4.6 and A5.6 outline means, in the form of voluntary tiers, for achieving enhanced construction levels by incorporating additional measures for residential and nonresidential new construction. Voluntary tiers may be adopted by local governments and, when adopted, enforced by local enforcing agencies. Buildings complying with tiers specified for each occupancy contain additional prerequisite and elective green building measures necessary to meet the threshold of each tier. See Section 101.7 of this code for procedures and requirements related to local amendments, additions or deletions, including changes to energy standards.

    [BSC & HCD] Where there are practical difficulties involved in complying with the threshold levels of a tier, the enforcing agency may grant modifications for individual cases. The enforcing agency shall first find that a special individual reason makes the strict letter of the tier impractical and that modification is in conformance with the intent and purpose of the measure. The details of any action granting modification shall be recorded and entered in the files of the enforcing agency.

    SECTION 305 [OSHPD 1]— CALGreen TIER 1 AND CALGreen TIER 2

    305.1 CALGreen Tier 1 and CALGreen Tier 2 buildings contain voluntary green building measures necessary to meet the threshold of each level.

Frequently asked questions

Who must follow Chapter 3 scoping rules?

All projects regulated by CALGreen use Chapter 3 to determine which green measures apply—Chapter 3 defines project scope, mixed‑occupancy application, phased projects, and voluntary tiers (see §§301.1, 302.1, 303.1, 304.1) .

Do additions or tenant improvements always trigger CALGreen requirements?

Additions and alterations trigger requirements only as specified: residential additions/alterations that increase conditioned area, volume, or size follow Chapter 4 provisions within the altered area (§301.1.1), and nonresidential additions/alterations follow the thresholds set in §301.3 (e.g., additions ≥1,000 sq ft or permit valuation limits) .

How are mixed‑use buildings handled?

Each portion of a mixed‑occupancy building must comply with the green measures applicable to its specific occupancy; CALGreen provides exceptions for certain accessory structures and live/work units in §302.1 .
