Mountain View FAQ
Does the plan require my home to go electric?
Not directly. The plan sets county-operations targets and reach-code updates for new construction in unincorporated areas. Existing homes face no retrofit mandate yet, though incentives encourage heat-pump and induction conversions through BayREN and SVCE programs.
How does the plan apply to incorporated cities?
Most actions target unincorporated areas and county operations. Cities like San Jose and Sunnyvale run their own climate plans. The county funds regional programs — fleet electrification, tree canopy, EV charging — that cities can join through partnerships.
San Jose FAQ
Can I still install a gas stove during a remodel?
Existing buildings may keep gas appliances and replace like-for-like during minor remodels. Major additions, full reconstructions, and new construction trigger Chapter 17.84 all-electric requirements at plan review.
Does the reach code apply to ADUs?
Yes. New detached accessory dwelling units must be all-electric under SJMC Chapter 17.84, including heat pumps for space and water heating. Conversion ADUs in existing structures have limited exemptions.
