February 2026
This Information Bulletin addresses the implementation of California Assembly Bill (AB) 98, as amended by California Senate Bill (SB) 415, which establishes design and build standards for specified warehouse developments.
Definitions
The following definitions shall be used in the application of the statute.
- “Logistics Use Development” means a building that is primarily used as a warehouse for the movement or the storage of cargo, goods, or products that are moved to business or retail customers, or both, that does not predominantly serve retail customers for onsite purchases, and primarily involves the use of heavy-duty trucks to move the cargo, goods, or products. Logistics Use Development does not include any of the following:
- Facilities where food or household goods are sold directly to consumers and are accessible to the public.
- A building primarily served by rail to move cargo goods or products.
- A project that involves logistics facilities (including warehousing and transloading facilities) served by rail and intermodal freight transport services, where all facility structures and related rail operations are located within a single site footprint.
- A building that serves a primary agricultural use that is actively operated for a single period of 90 consecutive days or less each year.
- “Sensitive Receptor” means one or more of the following:
- A residence, including, but not limited to, a private home, apartment, condominium unit, group home, dormitory unit, or retirement home.
- A school, including, but not limited to, a preschool, prekindergarten, or school maintaining kindergarten or any of grades 1 to 12, inclusive.
- A daycare facility, including, but not limited to, in-home daycare.
- Publicly owned parks, playgrounds, and recreational areas or facilities primarily used by children.

- The following types or park and recreation areas shall not be considered a sensitive receptor:
- Nursing homes, long-term care facilities, hospices, convalescent facilities, or similar live-in housing.
- Hospitals.
- “Expansion” means an increase in size of an existing logistics use development by 20% or more of the existing square footage. Office space shall not be included as part of the existing square footage or in the square footage for the 20% threshold.
- “Heavy-Duty Truck” means a truck with a gross vehicle weight rating of 26,001 to 33,000 pounds (Class 7) or greater than 33,000 pounds (Class 8).
Siting and Truck Routing
Site Criteria
- Any new logistics use developments shall be sited on roadways that meet the following classifications:
- Arterial roads; or
- Collector roads; or
- Major thoroughfares; or
- Local roads that predominantly serve commercial, agricultural, or industrial uses. A road shall meet this requirement if more than 50% of the properties fronting the road within 1,000 feet of the logistics use development’s truck entrances and exits are designated for commercial, agricultural, or industrial use.
Additional information and a map of roadway classifications can be found on the Caltrans webpage.
- A waiver may be granted when siting on one of the designated roadway classifications is impractical due to unique geographic, economic, or infrastructure-related reasons. To receive a waiver, the applicant must demonstrate all of the following:
- There is no feasible alternative site that exists within the designated roadway classifications;
- A traffic analysis has been completed and submitted to the City;
- The site is an existing industrial zone or an existing industrial or agricultural zone for an agricultural-related logistics use project; and
- The proposed site will incorporate mitigations to minimize traffic and environmental impacts on residential areas to the greatest extent feasible.
Truck Routing
- Prior to the issuance of a certificate of occupancy or final inspection for a new or expanded logistics use development, the logistics use development operator shall establish and submit for approval a truck routing plan to and from the state highway system based on the latest truck route map of the city. The truck routing plan shall include the following:
- A description of the operational characteristics of the logistics use and of the logistics use development operator, including, but not limited to, hours of operation and types of items to be stored within the building.
- Proposed truck routing to and from the logistics use development to designated truck routes that, to the greatest extent possible, avoid passing sensitive receptors.
- Measures, such as signage and pavement markings, and queuing analysis for preventing truck queuing, circling, stopping, and parking on public streets.
- A revised truck routing plan shall be submitted prior to issuance of a business license for any new tenant of the property. The city shall have discretion to determine if changes to the truck routing plan are necessary, including, but not limited to, any additional measures to alleviate truck routing and parking issues that may arise during the life of the logistics use development.
Development Criteria
The following criteria apply to all new or expanded logistics use developments.
