California builders are reportedly pleased with the newest version of the state’s building code, which was adopted by the California Building Standards Commission in January and will take effect in 2014. The updated code clarifies the rules for accessible building, stipulating that single-family homes — unlike apartments and condos — need not be wheelchair-accessible. The streamlined accessibility requirements, it’s hoped, will help curb “drive-by lawsuits,” in which attorneys and advocacy groups were able to squeeze money from businesses perceived to be in violation of accessibility rules by threatening legal action if their demands weren’t met.
