Frequently Asked Questions

Who is responsible for hiring and paying for the special inspector?

Under CBC Section 1704.2.1, the project owner or their authorized agent, typically the architect or engineer of record, is responsible for retaining the special inspector, not the contractor. In practice, contractors often coordinate the scheduling, but the contractual and financial responsibility falls on the owner or their representative.

How do I schedule an inspection, and do I need to pay upfront?

Scheduling is easy: just call, text, or email us. No credit card is necessary to schedule; we bill you once our work is done. We’re available 7 days a week, including holidays, and accept cash, checks, and all major credit cards.

Are you licensed, certified, and insured?

Yes. Advantage Special Inspection is ICC-certified and registered for LA County and surrounding areas, and we carry both general liability and worker’s compensation insurance.

What is special inspection, and why do I need one?

Special inspection is an independent, code-mandated quality assurance process required under California Building Code Chapter 17 for critical structural work, including reinforced concrete, structural steel and welding, masonry, epoxy anchors, and shear walls. A certified special inspector verifies that the work matches your approved plans and Statement of Special Inspections. Without a completed special inspection record, your building department will not sign off on final inspection.
