Code Interpretations

What Are They?

Our interpretations, policies, or code alternates were written to provide guidance for our review staff and to ensure consistency of our reviews. While they may be used as guidance for yourdesign, they are subject to change without notice and their application to specific projects may vary.

For questions about how these code interpretations may apply to your project:

  • Contact the building code plan reviewer assigned to your application, if you’ve submitted a permit application
  • Visit the Applicant Services Center, if you haven’t yet started your project

To request an intrepretation of the meaning, application, or intent of any development regulation in our Land Use Code or Environmentally Critical Area regulations during a land use projects' comment period, see Comment on a Project.
