NEW!  Due to recent staff shortages and increased applications, the Building Division is experiencing delays in permit processing.  We have brought in additional outside consultant services and staff to minimize any delays.  We thank you for your patience and understanding at this time and look forward to returning to our normal level of service as soon as possible.  

Proposed Changes to the California Residential Building Code

The County of Napa Board of Supervisors has requested the Building department to provide recommendations of proposed changes to the California residential building code that would provide increased fire restrictive measures associated with light frame residential construction.

Through extensive research and consideration we addressed the areas that are most vulnerable to destruction caused by fire during an urban wildland fire event. The four areas addressed are as follows:

1. Eave length
2. Vented attics
3. Accessory structures
4. Deck and balconies

Please see Proposed Fire Resistive Measures for the details for the four (4) proposed changes we are suggesting to the board of supervisors for their consideration.

Change In Submittal Processes

In response to the County Health Order, we have implemented COVID-19 preventions protocols, including modifications to our submittal processes to reduce the need to visit our office.  

Please be aware due to the demand and workflow at this time emails and phone calls are taking 3-5 business days for a response.  

We thank you in advance for your patience and ask that our clients allow us to reply to your email or phone call as calling or emailing multiple times adds to the backlog and prevents other clients from receiving our services in a timely manner.
