Plain-language change summary

The updated version of Bill HB 1353 has reduced the percentage of self-certified program permit applications that must be audited each year from at least 20% to 5%. Additionally, it has clarified the process for conducting audits, ensuring there are random audits but leaving more discretion to the cities on how to implement them. These changes matter because they could make it easier for architects to participate in the self-certification program while still maintaining oversight to ensure compliance with building codes. This balance aims to streamline processes while ensuring safety and accountability in construction projects.
