Welcome to Building Division

Important Notice about the Trial ADU Fee Waiver program:

You may be familiar with the County of San Diego trial impact fee waiver that went into effect January 9th 2019. This was a trial waiver that was funded for 5 years that will be ending on January 9 th 2024 .

Projects that are started prior to January 9th 2024 will have plan check fees waived as they start the review process. Permit and all other impact fees are not collected until a project is ready to be issued and will not be covered if the permit is issued after the January 9th 2024 date. If your project is currently under review we will be working to provide any corrections as soon as possible so that your design team can work to update the plans and obtain your permit prior to 1-9-24. Please work with your design professionals to get plans updated and returned to the County so that projects may be approved in a timely manner.

If you have any questions about this trial program or you feel you will not be able to provide your plans for review prior to the 1-9-24 date please reach out to us at aduquestions@sdcounty.ca.gov.




The County reviews plans to the most recently adopted California Building Code, County of San Diego Amended Building Code, the County of San Diego Zoning Ordinance and General Plan. We understand that staying current with all of these requirements can be challenging and that there are portions of each referenced code that can be left to interpretation. That is why it is our goal to offer all of our customers an opportunity for a second opinion on any correction or interpretation that we have made during plan review or over the counter. If you as our customer feel that your interpretation of a requirement could be interpreted a different way, please ask for a second opinion.

Second Opinion

A second opinion is available on any interpretation or correction provided and will not affect the level of customer service you receive. We ask you to provide your interpretation of the code along with any health and safety concerns that the interpretation may cause and how this will affect your project. The second opinion will come from one of our senior staff or a supervisor who will have a chance to take a deeper look at supporting documentation on both sides of the issue. This may occur at the counter or require a few days for proper research and understanding of the intent of the code in question. After your second opinion you can always follow up with our Building Official for a final opinion.

The Project Issue Resolution (PIR) Conference

This is yet another opportunity for our customers to have interpretations reviewed and heard by Executive Management. A Project Issue Resolution Conference is a meeting that includes an applicant, our Executive Management team, and County Project Staff to discuss issues and identify solutions that were not able to be resolved with County Supervisors due to interpretations of code or other unique circumstances related to a project.
