2. Submit the application fee as marked on the application form. Make check payable to “The Department of Building and Safety, City of Los Angeles.”

Addition of a model to an existing approval requires submittal of Technical Modification. You need to perform the following steps:

1. Submit a completed Technical Modification application form (PC-ELEC-App.12). Original signature is required.
2. Submit the application fee as marked on the application form. Make check payable to “The Department of Building and Safety, City of Los Angeles.”
3. Submit a current production sample of the new equipment model. d. Provide a current new model product literature (brochure, operational instruction, maintenance manual, owner’s manual).
4. Photographs or drawings showing the exterior views and internal views of the new equipment.
5. Schematic wiring diagrams. Diagrams should identify the sizes of wires, ratings of fuses, circuit breakers, and other components.
6. The parts list for the components operating at or above 30 VAC or 24.8 VDC in dry locations or 15 VAC or 12.4 VDC in wet locations. Include the part's function, name of manufacturer, catalog number, electrical ratings, and testing agency component recognition or listing number.
7. For new model with unlisted transformers, drivers or power supplies with a rating of less than 1KVA, provide two samples with schematic wiring diagrams and specification sheets.

The steps are the same as regular approval, as follows:

Submit the following:

1. A completed application form (PC-ELEC-App.12). Original signature is required.
2. Application fee as marked on application form. Make check payable to “The Department of Building and Safety, City of Los Angeles.”
3. Current product literature (brochure, operational instruction, maintenance manual, owner’s manual).
4. Photographs or drawings showing the exterior views and internal views of the equipment.
5. Schematic wiring diagrams. Diagrams should identify the sizes of wires, ratings of fuses, circuit breakers, and other components.
6. The parts list for the components operating at or above 30 VAC or 24.8 VDC in dry locations or 15 VAC or 12.4 VDC in wet locations. Include the part's function, name of manufacturer, catalog number, electrical ratings, and testing agency component recognition or listing number.
7. Production sample of the equipment as follows:
   1. For General or Laboratory Approval: Submit a current production sample (complete and operable) with all appurtenances to operate the equipment. If the equipment is too heavy or large to ship to the laboratory, arrange for a field location in the City of Los Angeles or at the factory where a complete testing can be performed without on-site restrictions (call the laboratory for a prior arrangement) and pay for the field trip charges.
   2. For One-Time Approval of field installed equipment: Provide the field location where the equipment is intended to be installed insuring that it can be evaluated and tested without on-site restrictions. Provide the complete address, phone number, and contact person. Pay for the field trip charges.

However, the revised approval may require a new model designation of the previous product and the approval would be for the duration that was originally established for the equipment.

Current product literature, owner’s manual, schematic wiring diagrams and parts list, installation instruction (if applicable), and a production sample of the equipment with all the options and accessories.

The permit number, address, owner, description of work, A&E occupancy load, and signature.

An approved recognized electrical testing agency is a testing agency that obtains approval from the Department of Building and Safety to perform testing and listing and field evaluation. A list of these recognized testing agencies are posted on the LADBS web as follows on the "Electrical Test Lab (ETL)" page:

• Testing agencies that have approval for listing of equipment
• Testing agencies that have approval for one-time field evaluation

All construction work for which a permit is required shall be subject to inspection by authorized inspectors. An inspection must be performed before work is concealed or covered. It is your responsibility to notify the inspector when the work is ready for inspection. Work is generally inspected and approved in succession and no work may continue beyond the point indicated in each successive inspection without first obtaining the approval of the inspector. 

Common items to be inspected are foundation excavations, concrete work, wood framing, ventilation equipment, plumbing, electrical, shear wall nailing, roof nailing etc. When completed, there shall be a final inspection and approval of the completed project.

The purpose for which a building, or part of a building, is used or intended to be used.

It is an order to correct a code violation.

Plan check is when your building plans are reviewed to make sure they comply with basic safety, engineering and planning rules. LADBS plan check engineers will review the design of such things as the structure, plumbing and electrical systems to make sure they are safe and properly designed. They will also look at other items, like building setbacks, heights and lot coverage to see that the construction is compatible with the neighborhood.

Plan check is part of the permit process. If your project disqualifies you from directly receiving an Express Permit, you will need to have a plan check. If it's a small project, a Counter Plan Check will suffice. If it's a large project, you might need to have a Regular Plan Check, where your plans are submitted and reviewed over the period of several weeks.
