CNI-014 Special Inspection Agency Recognition List

Version: 11/18/2020

Special Inspection Agencies approved to perform services in unincorporated Sonoma County are listed below. Agencies have not been evaluated for Geotechnical Special Inspection. Other agencies and individual special inspectors may also be qualified. Permit Sonoma's Building Division has ultimate responsibility for approval.

Note: In general, Permit Sonoma does not maintain lists of design and development professionals. However, there are a few occasions for which we allow third party inspections. In these cases, we maintain public lists of inspection agencies.

Categories on this page (some agencies may be in more than one category):

  • Reinforced Concrete
  • Prestressed/Post-Tensioned Concrete
  • Structural Masonry
  • Structural Steel Welding/Bolting
  • Spray-Applied Fireproofing Tests Only
  • Unreinforced Masonry Push/Torque
