ORDINANCE TO INCREASE ENERGY EFFICIENCY IN EXISTING RESIDENTIAL BUILDINGS

The City of Sunnyvale is implementing an ordinance to increase energy efficiency in existing residential buildings by requiring the installation of heat pump air conditioning systems when standard systems reach the end of their life. This regulatory action is designed to reduce greenhouse gases and align with the goals established in the city's Climate Action Playbook. The scope applies to existing building remodels, additions, and alterations to ensure the protection and enhancement of the environment and local natural resources. The project is located in Sunnyvale, Santa Clara County, and is managed by Suzanne Park, the Chief Building Official. Under the California Environmental Quality Act, the ordinance is granted a Notice of Exemption under categorical exemptions Class 8, Section 15308, as well as sections 15307 and 15301(a), because it involves regulatory actions to protect the environment and alterations to existing buildings without expanding their use. The forecast was posted on October 31, 2025, under NAICS code 238220.
