Modifies provisions governing various property rights

HB 1796 repeals existing Missouri property rights laws and replaces them with new provisions focused on building codes and homeowner access to permits. It prohibits local governments (counties, municipalities, fire districts) from requiring one- or two-family homes, condos, or townhouses to meet specific "green" or energy efficiency standards beyond the 2009 International Residential Code (IRC) or International Energy Conservation Code (IECC). The bill also creates the "Building Permit Reform Act," exempting owner-occupants of single-family homes from needing licenses or certifications to perform their own renovations, with a potential $5,000 fee if the property is sold within one year. Violating these restrictions makes the local ordinance null and void.
