Local ordinances implemented to preserve the visual character of residential and commercial buildings were voided when Gov. Greg Abbott signed House Bill 2439 into law June 14. As of Sept. 1, government entities cannot enforce building material standards stricter than those set by the national building code, according to a bill analysis by the House Research Organization. For Richardson, HB 2439 nullifies portions of its comprehensive zoning ordinance, including a piece that requires residential and commercial buildings to have at least 75% and 85% masonry, respectively. Richardson Development Services Director Michael Spicer said developers now have discretion over which building materials they use. They can also change material plans once they have been approved by the city; however, such changes may still be subject to obtaining permits or plan amendments, Spicer said.
