From The Daily Wire:

Steven Greenhut, the Western region director for R Street Institute, told the Catholic Register in 2018 that he blamed the lack of adequate housing in California on the state, asserting, “We’ve screwed up the whole housing market through all these regulations.” The Catholic Register noted, “Local fees on building can add an additional 6% to 18% to the cost of a home. Energy-efficiency regulations add to the cost of a home as well: A recently enacted California rule mandating solar panels on nearly all new home construction will add about $10,000 to the total cost. In Los Angeles, energy-efficiency requirements increase building costs by 10%.”
