Step 5: Development Application Submittal

Step 5: Development Application Submittal

The City will review your submitted development application and associated construction documents before granting approval to start construction. Various forms need to be prepared and submitted during this stage. 


Action Items:

  • Prepare the ADU Optional Zoning Review Application (CDD-0009)

  • Submit the ADU Optional Zoning Review Application (CDD-0009)

  • Obtain approval of the ADU Optional Zoning Review Application (if submitted)

  • Submit a tree permit (if applicable)

  • Finalize building design

  • Prepare and submit construction documents for plan review

  • Obtain approval of building permit

  • Pay the appropriate permit fee and other applicable fees


A building permit is required for all ADUs. No separate planning or zoning approval is required before a building permit application may be submitted.

However, if you would like Planning to review your ADU plans prior to submitting a building permit application, you may submit an ADU Optional Zoning Review Application (CDD-0009). The application is an optional, low cost-process to verify your application meets zoning standards before spending significant time and money on a complete building permit application. 

When a building permit is submitted, The Building Division will route your project to other City Departments and Divisions, and outside regulatory agencies for review of compliance with zoning requirements, building code, and other applicable requirements, such as water and sewer. This process is known as Building Plan Review. Once the Building Plan Review process is complete and it has been determined your project complies with all the requirements, you will be able to obtain your building permit to begin construction.
