Summary of California Code Changes in the 2025 edition of Title 24

The Cupertino Community Development Department would like to highlight some State laws that pertain to the inspection and maintenance of exterior elevated elements (such as decks, balconies, and stairways) in buildings with three or more multifamily dwelling units. The owners of these properties are required to hire a licensed professional to perform the required inspections and produce a report to identify any hazardous conditions. The deadline to have the initial inspection completed is January 1, 2026.

Summary of the key provisions of the State laws

Inspection Requirements:

• Exterior elevated elements (balconies, decks, stairs, etc.) in qualifying buildings must be inspected by licensed professionals (architects, engineers, or certain qualified contractors (A, B, or C-5)) to ensure safety.
• Inspections must be done by January 1, 2026, and then every six years thereafter.
• The inspection aims to ensure the safety and structural integrity of these elements and to identify any hazardous conditions, such as decay or improper alterations.

Inspection Report:

• A written report must be submitted to the building owner within 45 days, detailing the condition of exterior elevated elements, with recommendations for further action if needed. Reports should include photographs and results of the evaluation.
• If the inspector finds any immediate safety concerns, the report must also be sent to the local enforcement agency (Cupertino Building Division) within 15 days.  Report shall be sent to permitcenter@cupertino.gov.

Repair and Maintenance:

• If repairs are needed, they must be completed by a licensed contractor and follow relevant building codes and specifications.
• If immediate safety threats are identified, repairs must be made immediately, and access to the affected area may be restricted until repairs are completed.

Penalties for Non-Compliance:

• If the building owner fails to make the necessary repairs within 180 days, they may face civil penalties and be subject to a building safety lien.
• The local jurisdiction can enforce these penalties and foreclose on the lien if necessary.

Sale or Conversion of Buildings:

• If a building is proposed for conversion to condominiums, an inspection must be done before the first sale or closing, and any necessary repairs must be completed and confirmed by the inspector.

Local Jurisdiction Authority:

• Local enforcement agencies can impose additional requirements and recover enforcement costs.
