Administrative Rules

Chapter 24.20 of the City of Portland building regulations authorizes the BDS Director to adopt and enforce written rules concerning the conduct and administration of special inspections. The Bureau of Development Services administers these rules, which are set forth in the Special Inspection Program Administrative Rules.


The Administrative Rules set forth the responsibilities of special inspectors, structural observers, testing agencies and approved fabricators. The Administrative Rules also set forth the qualifications necessary for special inspectors, testing agencies and fabricators to attain and maintain certification.

The Administrative Rules were developed cooperatively by BDS with representatives of the structural and architectural associations of Oregon, special inspection agencies and contractor associations.
