MODERATE
The bill was certified as passed by the legislature and includes significant updates to commercial building energy standards. Key changes include expanding exemptions to cover schools and hospitals facing financial hardship, adding historic preservation and pandemic-related economic losses as valid reasons for exemption, and clarifying that industrial buildings with non-exempt tenant spaces are still covered. Enforcement rules were updated to allow penalty pass-throughs to tenants only if they actively assist the owner with compliance.
Scope change
The bill's scope was expanded to include specific types of buildings (schools, hospitals) under financial hardship exemptions and clarified that industrial buildings with non-exempt tenant spaces remain subject to the standard.
ELIGIBILITY

Added exemptions for K-12 schools and private schools facing financial hardships like failed bond measures or debt capacity limits.

Added exemptions for public hospitals lacking the debt capacity to cover compliance costs.

Added 'historic integrity' as a valid reason for exemption, covering properties on national or state historic registers.

Added exemptions for buildings that suffered significant assessed value losses since the COVID-19 pandemic, preventing owners from securing loans.

Clarified that industrial buildings are exempt only if the non-exempt tenant spaces do not exceed 50% of the total square footage.

ENFORCEMENT

Modified penalty rules to allow building owners to pass costs to tenants only if tenants provide data, access, and cooperation to facilitate compliance.

Extended the validity of compliance extensions to two years, with an option to renew or file for an exemption afterward.

REQUIREMENT

Added a requirement for building owners to submit documentation proving that more than 50% of the building's square footage is affected by partial exemptions to qualify for an exemption.
