The fee must be proportional to the average size of all dwelling units on the Lot. Floor plans showing the sizes of all units may be required to make this determination. An applicant may  choose to pay the full fee in lieu of providing these plans.

Square footage, square-feet and size are used in the ADU Ordinance to refer to various direct ADU size regulations (such as the 1,200 square foot limitation). These terms refer to the definition of Floor Area in LAMC 12.03, but does not include the definition of Residential Floor Area (RFA), nor does it include any non-conditioned spaces such as porches, patios or breezeways with solid or lattice roofs. Physically connected spaces that are conditioned but do not have an interior connection to the ADU are also not counted as ADU square footage. This definition does not apply to a Movable Tiny House (MTH), which is subject to distinct size provisions as described in the definition of a MTH.

Indirect limits on ADU size through other zoning provisions such as Floor Area Ratio (including RFA in the R1, RE, RS and RA zones) or lot coverage may apply separately which may further limit allowable ADU square footage. Refer to LAMC 12.22 A.33(b) for more information on applicable development standards.

Only products that have either a Laboratory or General Approval (no one-time approvals) may be subject to annual renewal. About 60 days before an approval expires, the original applicant needs to take the following actions:

1. Submit a completed renewal 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 equipment along with an explanation if there were any changes to the equipment from the previous approval.

Submit an “Application for Testing or Evaluating Mechanical Equipment” (found on the "Mechanical Test Lab (MTL)" page) to LADBS-MTL, check the box “renewal” and pay the fees. 

Additional information, tests, and/or engineering analysis may be required, in which case written comments will be sent to the applicant.

Projects that have paid a plan check fee and had their plans accepted by LADBS prior to the effective date of the ADU Ordinance (December 19, 2019) are provided a vested right to proceed with its development in compliance with the development rules and regulations in force on the date that the plan check fee was paid. Applicants that wish for their projects to take advantage of new provisions in the ADU Ordinance (and state law) will need to file a supplemental permit application, which will void the vesting rights under the prior development rules and subject the project to the new ADU Ordinance and any other new regulations.
