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.
