Licenses & Inspections is IAS Accredited

The Department of Licenses and Inspections is reaccredited by the International Accreditation Services (IAS). The Department has been accredited by IAS since 2013, demonstrating the Department’s competency and commitment to public safety based upon nationally recognized standards.

Our triennial reassessment happened in September 2023. A team of expert building code officials from across the country conducted an in-depth review of our permitting process. They shadowed our staff in every stage of permitting and inspections, conducting interviews with key stakeholders, assessing standard policies and procedures, and evaluated overall performance.

This accreditation renewal is a testament to the Department’s continued excellence in code enforcement. Thank you to all our stakeholders who participated in these interviews and congratulations to our L&I staff.
