Drought is Here - A mandatory 20% reduction in water use is currently in effect for City of Sonoma Water Customers.


Ben Plan ReviewBeginning January 1, 2020, the 2019 California Green Building Standards Code (CALGreen) becomes effective for new buildings and certain addition or alteration projects throughout California. The City of Sonoma has adopted and amended CALGreen to require CALGreen+Tier 1 level of compliance for all new buildings (except Tier 1 Energy Efficiency measures need not be met). The City of Sonoma requires that project applicants hire a third-party green building special inspector to verify compliance with CALGreen requirements as amended by the City of Sonoma. Please use the applicable customized City of Sonoma checklist found below to document compliance for your project.

(NEW) CALGreen Checklists for building permit applications submitted after January 1, 2020:
