An applicant for Deputy Inspector shall provide written documentation to the Superintendent of Building demonstrating the applicant’s competence and relevant experience or training. Experience or training shall be considered relevant when the documented experience or training is related in complexity to the same type of special inspection activities for projects of similar complexity and material qualities. These qualifications are in addition to qualifications specified in other sections of this Code. Application for registration as a Registered Deputy Inspector shall be made to the Superintendent of Building on a form furnished by the Department.

But, prior to that action, the holder shall be given an opportunity to appear before the Superintendent of Building and be heard. Except where there is a City employee inspecting buildings or structures being erected or repaired by the City, no Registered Deputy Inspector shall receive any compensation from the City. A Registered Deputy Inspector shall undertake and perform the duties of inspection solely on the request of the owner or the owner’s agent. The designation shall be deemed to indicate that the duties incident to the inspection are within the course and scope of the Registered Deputy Inspector’s employment by the owner or agent, and except where the Registered Deputy Inspector is in fact an employee of the City, the Registered Deputy Inspector shall not be deemed an employee of the City, a contractor, a subcontractor or a material vendor for any purpose.

The report shall be made on forms supplied by the Department and shall be filed with the Department. 2. Nothing here shall be deemed to authorize any Registered Deputy Inspector to approve any inspection required by this Code, other than the special inspection for which the Registered Deputy Inspector was hired and is of the type for which the Registered Deputy Inspector is registered. 3. Where, in the opinion of the Department, the magnitude or complexity of a job warrants it, additional Registered Deputy Inspectors may be required. 4. Where, in the opinion of the Department, the Registered Deputy Inspector is negligent in the performance of the Deputy Inspector’s duties, the job shall be stopped. 5.

Certifications by Engineer or Geologist. If the grading or foundation earthwork has required continuous inspection, the responsible engineering geologist or soils engineer shall certify by signature to the Department that, to the best of the geologist’s or engineer’s knowledge, the field work was completed in conformity with the technical design data. (Readopted by Ord. No. 188,797, Eff. 12/31/25.) 91.1705.1.3. Department's Responsibility. The employment of a Registered Deputy Inspector for any work does not deprive the Department of the right to make periodic or called inspections of all or portions of the work. On any work requiring continuous inspection by a Registered Deputy Inspector, the called inspections required by Section 91.108 of this Code may be delegated to the Registered Deputy Inspector by the Superintendent of Building. (Readopted by Ord. No. 188,797, Eff. 12/31/25.) 91.1705.1.4. Structural, Termite and Fungus Damage. Every building raised from its foundation shall be inspected. If there is any superficial evidence of structural damage, termites or fungus growth, the permittee shall remove and renew the damaged or infested members before reseating the building or moving it from its existing site or into the City. (Readopted by Ord. No. 188,797, Eff. 12/31/25.) 91.1705.1.5. Emergencies or Catastrophes. In the event of an emergency or of a major catastrophe in the City, the Department may deputize Emergency Building Inspectors for the Department.

In addition to the construction or work inspected as described in LAMC Sections 91.108 and 91.1704 through 91.1705, there are other construction activities that are sufficiently important to the structural stability of the structure, the occupants of and the fire and life safety of the structure that inspection by a specially qualified inspector is necessary in order to ensure compliance with the Code requirements. These special activity inspections may occur during off-site fabrication or during on-site construction. Inspections by Department Approved Special Activity Inspectors will be required in accordance with regulations promulgated by the Superintendent of Building where: 1. The structure is more than five stories or 60 feet (18 288 mm) in height. 2. The structure exceeds 50,000 square feet (4645 m 2 ) of ground area or 200,000 square feet (18 580 m 2 ) of total floor area. 3. Nondestructive structural testing methods are utilized. 4. The quality identification markings of the materials used are not inspectable after installation. 5. The manner of use of materials precludes full inspection after installation. EXCEPTION: The Department may waive continuous or periodic inspection required by this Section where minor quantities are involved and no unusual hazards exist.

For buildings exceeding 160 feet (48 768 mm) in height, the engineer responsible for the structural design and the general contractor responsible for the construction, or their competent authorized representatives, shall make periodic inspections of the work at the site to verify general compliance with the approved plans, specifications and change orders. The engineer and general contractor shall submit a statement in writing to the Department stating that they know from personal knowledge that the materials installed and the structural work performed is in compliance with the approved plans, specifications and change orders. The phrase "personal knowledge" as used above in reference to the engineer and general contractor means the knowledge resulting from the general observation by the engineer and the general supervision by the contractor of the work, as required by both in the superintendence of the building's construction, and as distinguished from the continuous personal superintendence of the special inspector and/or deputy inspector who are continuously at the site during the progress of the work. The exercise of reasonable diligence to obtain the facts is required and anyone who intentionally remains unaware may be charged with knowledge. The interpretation of personal knowledge as it applies to the special inspector and/or deputy inspector is that the inspector(s) must have actual personal knowledge that the requirements of the plans and specifications are being carried out, which is obtained by the inspector's continuous observation of the work of construction at the site in all stages of its progress.

Base metal thicker than 1.5 inches (38 mm), where subject to through-thickness weld shrinkage strains, shall be ultrasonically tested for discontinuities behind and adjacent to those welds after joint completion. Any material discontinuities shall be accepted or rejected on the basis of ASTM A 435 or ASTM A 898 (Level 1 criteria) and criteria as established by the registered design professional(s) in responsible charge, and the construction documents. 91.1705.18.2. Fire-Resistant Joint Systems. Inspection of fire-resistant joint systems that are tested and listed in accordance with CBC Sections 715.3 and 715.4 shall be conducted by an approved deputy inspector in accordance with ASTM E 2393.
