Understanding Compliance with Senate Bill 326 in California

In January 2020, California saw the enactment of Senate Bill 326, a significant piece of legislation affecting residential buildings. This bill, also known as Civil Code Section 5551, emphasizes the necessity of ensuring safety and maintenance, especially for structures with exterior elevated elements. Compliance with SB 326 isn't just about obeying the law; it's about safeguarding residents and maintaining structural integrity. This article explores the ins and outs of SB 326 compliance, covering key areas like reserve studies, waterproofing systems, load-bearing components, and the role of enforcement agencies.

Reserve Study and Physical Assessment:

A crucial aspect of SB 326 compliance involves conducting thorough reserve studies and physical assessments. These evaluations, required by law, must be carried out by licensed professionals like structural engineers or architects. They entail detailed examinations of load-bearing components, waterproofing systems, and any wood-based materials used in construction.

Visual Inspections and Sample Size:

SB 326 mandates comprehensive visual inspections of exterior elevated elements to assess their condition and identify potential hazards. Additionally, the bill stresses the importance of sampling a significant portion of the building's elements to ensure reliable assessment results with a minimum 95 percent confidence level.

Enforcement Agencies and Compliance:

Local enforcement agencies are tasked with overseeing SB 326 compliance. Collaboration with these agencies is vital for property owners and managers to navigate the law effectively. Non-compliance can lead to penalties imposed by the code enforcement agency, highlighting the importance of following regulatory requirements.

Wood-Based Products and Structural Components:

SB 326 focuses on scrutinizing wood or wood-based products used in exterior elevated elements. It necessitates thorough inspection and maintenance of these components to uphold structural integrity and mitigate safety risks associated with potential deterioration.

Compliance Deadlines and Obligations:

Property owners and managers must stay informed about SB 326 compliance deadlines. By January 1, 2025, all residential buildings with exterior elevated elements must adhere to the law's provisions. Timely compliance is essential to avoid legal consequences and ensure resident safety.

Enforcement Procedures and Reporting:

Following inspections and assessments, property stakeholders must promptly report their findings to the relevant enforcement agency within 15 days. Reports should detail inspection results, repair recommendations, and a comprehensive action plan for achieving SB 326 compliance.


Senate Bill 326 brings significant changes to California's residential building regulations, emphasizing safety and compliance. Compliance requires meticulous attention to detail, collaboration with enforcement agencies, and adherence to deadlines.

As the January 1, 2025 deadline approaches, prioritizing SB 326 compliance is essential to maintain safety standards and protect residents. By proactively addressing requirements and fostering a culture of compliance, property stakeholders can navigate SB 326 effectively and ensure the well-being of occupants.
