Starting January 1, 2020, all new homes built in California will be outfitted with solar panels. The new rule will apply to all homes, apartment buildings, and condos three stories or under.
The California Energy Commission voted unanimously for the housing mandate, which also includes new insulation and air filter requirements for newly built homes. More than 80,000 new homes are built every year in California. The requirements are expected to add $9,500 to the cost of a home, or $40 a month on a 30-year-mortgage. However, the energy savings to the homeowner will save $80 a month, making the measure not just energy smart but money smart.
