Inspections

The inspection function is one of the more important aspects of the Building Division operations along with the plan review function. The code intends that all construction or work for which a permit is required shall be subject to inspection by the Building Division.

Inspections are done to insure that the work covered by the permit is done according to the plans and is in compliance with all the model codes and ordinances adopted by various County agencies, i.e., Zoning/Planning, Fire Prevention, and Flood Control.

It shall be the responsibility of the owner or the licensed contractor doing the work authorized by a permit to notify the Building Official when said work is ready for inspection. No portion of any building, structure, wiring, plumbing, duct work, or equipment that is required to be inspected shall be covered or concealed without approval of the Building Official.

Wiring/conduit locations, support, and protection. GFCI and smoke detector circuits, laundry and kitchen circuits. Clearances at sub-panels and service entrance equipment. Rated boxes in fire separations.




  • Insulation

Check for compliance with Title 24 requirements.




  • Exterior Lath/drywall and Interior Lath

  • Firewall integrity, self-closing solid core door

  • Compliance with Title 24 energy and handicap as required

  • Special Inspections

The Building Department does not have the staff of inspectors to provide detailed inspections on large and complicated projects. This is true where the nature of the construction is such that extra care in quality control must be exercised in order to assure compliance with the code. The code specifies that the special inspector be employed by the owner.

Special inspection is required when:
  • concrete strength is over 2,500 psi

  • concrete stem wall

  • shotcrete

  • post-tensioning system

  • structural masonry

  • field welding/high-strength bolting

  • piling/caissons

  • special cases (when ordered by Building Official)



  • Structural Observation

Due to the critical nature of construction in our jurisdiction which is Seismically active, this division requires that the engineer or architect of record be employed by the owner to provide observational visits to the site to obtain compliance with the structural drawings, for certain projects.

For more information, refer to policy memo on: Structural observation
