Vehicles: transportation of manufactured homes.

The bill now covers 'factory-built housing' and 'commercial modular' in addition to 'manufactured home' throughout Section 35790, expanding which types of prefabricated structures can use the overwidth permit process for units up to 14 feet wide.

New definitions added: 'factory-built housing' (defined by Health and Safety Code Section 19971) and 'commercial modular' (defined by Health and Safety Code Section 18001.8).

Permit issuance language changed from 'shall issue' to 'may issue,' making it discretionary rather than mandatory for the Department of Transportation or local authority to grant overwidth permits.

Entirely new Section 35790.1 added, establishing detailed conditions for moving manufactured homes between 14 and 16 feet wide, including: service brakes on all wheels, breakaway brake battery requirements, maximum axle weight of 6,000 pounds and wheel weight of 3,000 pounds, minimum tire tread depth of 2/32 inch, manufacturer and dealer certification of compliance documents, hitch and coupling device standards, identification plate requirements, lighting rules, side covering requirements, and pilot car or special escort services.

New Section 35790.2 requires the Department of Housing and Community Development to convene a stakeholder workgroup by March 31, 2027, meeting at least quarterly, with a report due to the Legislature by January 1, 2029. The workgroup must examine pilot car/escort requirements, feasibility of a single CHP escort crew across multiple jurisdictions, comparison to other states, and a potential 30-day oversize load permit for loads up to 16 feet in height and width.

State-mandated local program determination changed from 'yes' to 'no.' The reimbursement provision was replaced with a statement that no reimbursement is required because the act creates a new crime or changes the definition of a crime within the meaning of Section 17556 of the Government Code.

Section 35790.1(p) prohibits the Department of Transportation from issuing a permit to move a manufactured home over 14 feet wide unless it determines all conditions in that section have been met, creating a new enforcement gate.

The entire amendment to Vehicle Code Section 35790.1 was deleted. This section had authorized permits for manufactured homes between 14 and 16 feet 8 inches wide, with specific height (15 ft 8 in), length (120 ft), and weight (120,000 lbs) limits, plus detailed technical requirements for brakes, tires, hitches, lighting, side coverings, certification documents from manufacturers and dealers, pilot car requirements, and a prohibition on issuing permits unless all conditions were met.

The state-mandated local program designation was changed from 'yes' to 'no,' meaning the bill no longer triggers state reimbursement obligations to local agencies for costs mandated by the state.

Permit issuance language changed from 'shall issue' (mandatory) to 'may issue' (discretionary). While the explicit 'good cause appears' standard from existing law is removed, agencies now have broader discretion to deny permits rather than being required to grant them.

Removed the provision that prohibited the Department of Transportation or a local authority from imposing any technical or prescriptive requirement not described in the section that would prevent an applicant from obtaining a permit.

Removed the exemption from pilot car requirements. The prior version had stated that a permitted manufactured home move is exempt from any code requirement for a pilot car in front of the home on a four-lane highway or behind it on a two-lane highway.

All amendments to Vehicle Code Section 35790.1 were removed from the bill. This section had provided for permits for manufactured homes between 14 feet and 16 feet 8 inches wide, with specific height (15 ft 8 in), length (120 ft), and weight (120,000 lbs) limits. The bill no longer modifies this provision.

State-mandated local program designation changed from 'no' to 'yes,' formally recognizing that the bill imposes costs on local agencies that may require state reimbursement under the California Constitution.

Section 35790(a)(1) changed from discretionary issuance ('may... if good cause appears') to mandatory issuance ('shall issue') for permits covering manufactured homes in excess of the standard maximum width up to 14 feet total width.

Removed 'any additional conditions imposed by the public agency' from the annual permit provision in Section 35790(c)(3), limiting annual permits to only the conditions stated in the section itself.

Added 'exclusive of lights and devices provided for in Sections 35109 and 35110' to the width measurement language in Section 35790(a)(1), clarifying that lights and devices do not count toward the 14-foot width limit.

Fiscal committee review changed from 'no' to 'yes,' indicating the bill now requires fiscal analysis, likely due to the state-mandated local program costs associated with requiring local jurisdictions to modify their permit approval processes.

New Section 35790 created to govern permits for manufactured homes up to 14 feet wide, previously only Section 35790.1 (homes over 14 feet) was addressed.

Maximum allowable width for a permitted manufactured home raised from 16 feet to 16 feet and 8 inches in Section 35790.1.

Fiscal committee review changed from 'no' to 'yes' and state-mandated local program changed from 'no' to 'yes,' reflecting the new obligations placed on local jurisdictions.

Permit issuance changed from discretionary ('may issue if good cause appears') to mandatory ('shall issue') for both Section 35790 and Section 35790.1, meaning agencies must grant permits when statutory conditions are met.

New dimensional and weight limits added for homes between 14 feet and 16 feet 8 inches: maximum height of 15 feet 8 inches, maximum length of 120 feet, and maximum gross weight of 120,000 pounds including the towing vehicle.

New 'annual permit' option created alongside the existing special (one-time) permit, allowing transporters to obtain a single permit covering multiple moves rather than applying each time.

Exemption from pilot car requirements for permitted manufactured homes on four-lane highways (front pilot car) and two-lane highways (rear pilot car), applying to homes up to 14 feet under new Section 35790(h).

New prohibition preventing Caltrans or local authorities from imposing any technical or prescriptive requirement not described in the statute that would block an applicant from obtaining a permit.

Definition of 'manufactured home' expanded to include components or modules of factory-built housing as defined in Health and Safety Code Section 19971.

New state-mandated local program provision (Section 3) requiring the Commission on State Mandates to determine if the bill imposes reimbursable costs on local agencies, with reimbursement under Government Code Part 7.
