The California Building Standards Commission has given its final approval to a new housing rule that is the first of its kind in the United States. Starting in 2020, the commission is requiring that all new homes built in the state include solar panels.
“These provisions really are historic and will be a beacon of light for the rest of the country,” said commissioner Kent Sasaki. “[It’s] the beginning of substantial improvement in how we produce energy and reduce the consumption of fossil fuels.”
In addition to the solar panel requirement, the new standard also includes an incentive for homeowners to add a high-capacity battery to their electrical system to store the sun’s energy. The rule does have an exemption for homes that are built in locations that are often in the shade.
California has a history of setting trends across the country, and this new rule is the next step in the state’s progressive environmental policy. The state has a goal of sharply reducing greenhouse gas emissions and drawing all of its electricity from renewable energy sources.
The California Energy Commission first endorsed the solar panel rule back in May as part of California’s Green Building Standards Code. This past week, the Building Standards Commission added the requirement with a unanimous vote.
Drew Bohan, executive director of the energy commission, said that the homes built under the new rule should use about 50 percent less energy compared to previous standards.
The new solar power requirement is for single-family homes and multi-family buildings up to three stories high. It will add about $10,000 to the upfront cost of a home, but the lower electricity bills should balance that out over time. Bohan said that over the course of a 30-year mortgage, a homeowner should save about $19,000.
Homeowners will have the option of buying the panels outright, leasing them or taking part in a power purchase agreement with the home builder.
