Depending on the size your project, you may consider requesting an appointment with the Development Review Committee (DRC), which meets weekly and is composed of staff from all departments that require permits. For more information about the DRC, please email the Planning Division: [email protected].
Sprinklers must be installed in the following types of residential structures:
- New construction
- Residential Additions
- Accessory Dwelling Units
- Remodels - new/remodeled square footage is more than 50% of the existing space
In some cases, the water supply (water lateral) coming from the water main serving the structure is not big enough to support a sprinkler systems. In that case, the home owner will need to upgrade the water lateral. Contact the Public Works Department at 707-778-4546 for information about the water lateral upgrades.
