Structural Masonry Special Inspection in Arcadia
You just broke ground on a new CMU retaining wall behind a hillside home off Santa Anita Avenue, and Arcadia Building Services needs your special inspection documentation before they will sign off on the next phase. You check the calendar and realize the city is closed this Friday — it is one of their alternate Friday shutdowns — which means your permit window just got tighter. Advantage Special Inspection is based right here in the San Gabriel Valley, and we inspect seven days a week, including those alternate Fridays when the city is dark. One call and we are on your site, usually within 24 hours.

What Is Structural Masonry Special Inspection?
Structural masonry special inspection is a code-required field verification process mandated under Chapter 17 of the California Building Code (CBC). When a project includes load-bearing masonry, reinforced concrete masonry unit (CMU) walls, or grouted masonry assemblies, CBC Section 1705.4 requires a qualified special inspector to observe and document critical construction activities at the jobsite. The governing design and construction standards — TMS 402 (Building Code Requirements for Masonry Structures) and TMS 602 (Specification for Masonry Structures) — establish the material, placement, and quality benchmarks the inspector verifies against.
The purpose is straightforward: confirm that the masonry work in the field matches the approved structural drawings and meets the performance criteria the engineer of record specified. Without a passing special inspection report, the building department will not approve the work.

Types of Projects We Inspect in Arcadia
Residential construction — Single-family home additions, ADU foundations with CMU stem walls, hillside retaining walls, garden walls, and block fences over code-threshold height. Arcadia has a large inventory of older homes undergoing remodels and seismic retrofits that require new masonry elements.
Commercial projects — CMU wall construction for retail spaces, restaurant buildouts, office buildings, and mixed-use developments along Huntington Drive and First Avenue. Commercial projects in Arcadia typically require continuous special inspection for grouted masonry per the structural engineer's statement of special inspections.
Multi-family and condominium buildings — Reinforced masonry walls, elevator shafts, stairwell enclosures, and parking structure elements in mid-rise residential projects. Multi-family construction often involves complex inspection schedules with multiple grout pours per week.
Retaining walls and site walls — Grade changes throughout Arcadia's foothill neighborhoods frequently require engineered retaining walls. These structures demand special inspection for reinforcement placement, grout consolidation, and drainage provisions before backfill.
Working in Arcadia — What Contractors Need to Know
The City of Arcadia Building Services Division handles all plan check and permit issuance for projects within city limits. The office is located at 240 W. Huntington Drive, Arcadia, CA 91007, and can be reached at (626) 574-5416.
Counter hours run Monday through Thursday until 4:30 PM and Friday until 3:30 PM. Arcadia operates on an alternate Friday closure schedule, meaning the building department is closed every other Friday. If you are planning a grout pour or reinforcement inspection that needs signoff on a city-dark Friday, plan your submittals accordingly — or call ASI, because we work that day regardless.
All plan check submittals go through the Arcadia EDGE portal at ArcadiaCA.gov/EDGE. The city does not accept paper submittals. Your statement of special inspections, structural drawings, and inspector credentials should all be uploaded through EDGE before work begins.
ASI is ICC-certified and registered to perform special inspections in Arcadia. Our credentials are already on file, which means no delays getting your inspection program approved.
FAQ's
Do I need a special inspection for my block wall?
Yes, in most cases. CBC Section 1705.4 requires special inspection for structural masonry construction, including reinforced CMU block walls, grouted masonry, and any masonry that is part of the lateral force-resisting system. There are limited exceptions under CBC Section 1704.2 for certain small residential projects, but if your approved plans include a Statement of Special Inspections calling out masonry, you'll need a certified special inspector on site. Fire rebuild projects in Altadena that include structural masonry are no exception — LA County enforces CBC Chapter 17 requirements on all rebuild permits. When in doubt, check your plans or send them to us — we'll tell you.
Who is responsible for hiring and paying for the special inspector?
Under CBC Section 1704.2.1, the project owner or the owner's authorized agent is responsible for retaining the special inspector — not the contractor. The special inspector works as an independent third party, separate from both the contractor and the building department. In practice, contractors often coordinate the scheduling, but the contractual and financial responsibility falls on the owner or their representative (typically the architect or engineer of record).
What's the difference between a special inspection and a city building inspection?
A city building inspection is performed by a municipal building inspector who checks overall code compliance at specific milestones — foundation, framing, final. A special inspection is a separate, independent inspection required under CBC Chapter 17, performed by an ICC-certified special inspector retained by the project owner. Special inspections focus on specific code-critical work — like masonry grout placement, reinforcement, and mortar — that requires continuous or periodic observation beyond what a city inspector covers. You need both: the special inspection report is part of what the city inspector reviews before signing off.
What happens if masonry work is placed without a special inspector on site?
Work performed without required special inspection is considered unapproved work under the building code. The building department can require the work to be exposed, tested, or removed to verify compliance. In some cases, the masonry can be scanned or tested after the fact, but this adds cost and delays — and the results may not satisfy the building official. This is why CBC Chapter 17 requires the inspector to be on site during the work, not after.
Does the special inspector have to be registered with the building department?
Yes. CBC Section 1704.2 requires that the special inspector and the inspection agency be approved by the building official. Registration requirements vary by jurisdiction. ASI handles this process directly so you don't have to.
What happens if the inspector finds a deficiency during the masonry inspection?
The inspector documents the deficiency and notifies the contractor and masonry subcontractor immediately for corrective action. Common deficiencies include incorrect rebar spacing, insufficient grout consolidation, or cleanout issues. If the deficiency can be remedied while the special inspector is still on site, we'll write a completed report and your project keeps moving. If it requires more time than allotted for the inspection, a correction notice will be written and an additional special inspection will need to be scheduled. If the deficiency is not corrected, CBC Section 1704.2.4 requires that the correction notice be escalated to the engineer of record and the building official before that phase of work can be completed.
