Residential Energy Conservation Ordinance (RECO)

The purpose of RECO is to increase the energy and water efficiency in Berkeley residences. Compliance with RECO measures saves money, increases the comfort and reduces the amount of greenhouse emissions in homes. 

BESO to Replace RECO/CECO:
Effective December 1, 2015, Berkeley's Building Energy Saving Ordinance (BESO) will replace both the Residential and Commercial Energy Conservation Ordinances (RECO and CECO). The transition from RECO/CECO to BESO will occur between October 9, 2015 and December 1, 2015. For more information, see:

Effective October 9, 2015
