McKinney Building Inspections Department achieves top ISO ratings for safety standards

The McKinney City Council celebrated a significant achievement during their work session on April 15, 2025, as the Building Inspections Department announced a remarkable improvement in its ISO ratings. The department received a score of 2 in both residential and commercial building code enforcement, placing it in the top 1% and 2% of Texas building departments, respectively. This marks a substantial leap from previous scores of 3 and 5, showcasing a multi-point improvement that is rare in the industry.

Mayor and council members expressed pride in this accomplishment, emphasizing how these ratings can positively impact property insurance rates for residents. The ISO ratings are determined by evaluating various aspects of building code enforcement, and McKinney's scores reflect the dedication and expertise of its inspection team. The department's recent reaccreditation by the International Accreditation Service further underscores its commitment to maintaining high standards.

Council members acknowledged the leadership of Suzanne Arnold, who has played a pivotal role in guiding the team towards this achievement. The recognition of the hard work and professionalism of the inspectors was a highlight of the meeting, with calls for the team to stand and be celebrated for their contributions.

As the meeting transitioned into executive session, discussions included pending litigation and economic development matters, but the spotlight remained firmly on the Building Inspections Department's impressive ISO ratings, which promise to enhance the safety and security of the McKinney community.
