APA and BPA applications require multiple discipline plan reviews by Planning, Building and/or Civil plan review, which will require a building pre-application process.
ADU Pre-Approval (APA)
The APA record is for design professions who want to obtain non-site-specific preapproval of an ADU plan. Homeowners utilizing a preapproved ADU plan are still required to submit a site-specific building permit application documenting compliance with applicable zoning ordinance and building code requirements for that location.
Building Pre-Application (BPA) Process
The Building Pre-Application process provides staff with the opportunity to review all submittal documents for completeness before converting it to a building record (BLD) or a grading record (GRD), which starts the plan review process and ensures the applicant a comprehensive plan review experience.
The BPA record type is the "catch-all" category that may be used to start the permit application process for any type of permit application that does not qualify as a DEM, LPC or RER record. For example, if your project is a kitchen remodel, a commercial tenant improvement, or a new house/ADU, you should start with the building pre-application. All demolition permit and/or grading permit requests should begin as a building pre-application.
