Residential Energy Conservation Ordinance (RECO)

The Residential Energy Conservation Ordinance (RECO) BMC 19.16 was passed in 1987 to increase the energy and water efficiency in Berkeley residences. It required homes to complete up to 11 minimum energy efficiency measures when a home was sold or transferred or when a home underwent major renovations.

As of December 1, 2015, RECO has been replaced by the Building Energy Saving Ordinance (BESO). With BESO, the RECO requirements of installing energy and water efficiency improvement measures, is no longer required. Instead, BESO requires Berkeley building owners to complete energy assessments and publicly report the building's energy efficiency information with the goal of helping building owners save energy and motivating them to participate in whole-building energy efficiency programs.

To learn more about BESO and check if a home is BESO compliant, see
