ADU Builder in Sonoma County
Project scope may include:
• Detached backyard ADUs
• Attached ADUs and additions
• Garage conversions
• Interior build-out and finish work
• Kitchen and bathroom installation
• Site coordination and construction planning
Our process:
1. Project conversation: goals, site, rough scope, and priorities.
2. Preconstruction: plans, selections, logistics, and an agreed construction scope.
3. Construction: organized execution with regular communication.
4. Completion: final details, walkthrough, and closeout.
Create flexible living space for family, guests, rental use, work, or the next chapter of your Sonoma County property. An accessory dwelling unit is a major investment with a lot of moving parts. Salty Builder brings the construction scope together so decisions about layout, materials, systems, and finishes stay connected to the way the space will be used.
