The Building Division is responsible for managing the construction permitting process. This process includes general public information, plan submittal, plan review, permit issuance, inspection and document retention. The Building Division is also charged with the task of assuring that all additional approvals required by both inside and outside entities are obtained prior to the issuance of both a building permit and receiving final inspection approval.

Process Overview:

The following is provided to help you understand and navigate Napa County's building permit process.  A process flowchart is available for your review and use. The flowchart illustrates the involvement of other County Departments, and state and local agencies that may assist us in our review process depending on scope of your project. If you need assistance or need clarification regarding the permitting process, please feel free to contact us.

Once you have prepared all required documents, you must submit those documents at the Building & Development Division counter. At the time of submittal, you should be prepared to provide the following:Building Plans and Code

For building a new residence, a submittal checklist is available to assist you in determining what kinds of documentation will be required. If you are altering an existing residential structure, we have a submittal checklist to help you too. Commercial projects have their own unique requirements. Please consult the commercial construction checklist prior to submitting your plans.

Quick Permits:

Quick Permits is an accelerated building permit process for minor projects that qualify as "Quick Permits." Not all permit types qualify. The types of projects that would qualify would be agricultural buildings, carports, decks, garages, gazebos, retaining walls and other various small projects. Each scope of work is subject to review and may or may not qualify. All completed applications for the Quick Permit program will be plan reviewed and you will receive comments on the plans within 7-10 business days. See if your project qualifies by reviewing the Quick Permit Overview and Quick Permit Requirements.
