Building Energy Saving Ordinance (BESO)

BESO to replace RECO/CECO 
Effective December 1, 2015, Berkeley's Energy Saving Ordinance (Berkeley Municipal Code 19.81) will replace both the Residential and Commercial Energy Conservation Ordinances (RECO and CECO). With BESO, the RECO/CECO requirements of installing energy and water efficiency improvement measures, will no longer be required.

Transition Period: The transition from RECO/CECO to BESO will occur between October 9, 2015 and December 1, 2015.  As of October 9, 2015, RECO and CECO requirements will no longer be required at time of building renovation due to enhanced energy codes and CalGreen standards. For buildings up for sale between October 9 to December 1, 2015, sellers may choose to either complete RECO/CECO measures or a BESO assessment. As of December 1, 2015, all new sales transactions of medium and small buildings, including homes, must comply with BESO. Previous completion of requirements under RECO/CECO will not fulfill BESO requirements. For more information on the transition schedule, see: Transitioning from RECO/CECO to BESO.
