ADU Drawings and Permit Coordination in the SFV

Drawings work best when the construction scope is clear

A good ADU process keeps design, permit requirements, and construction scope aligned. BBC ADU helps coordinate the plan set and permit path with the right professionals so the build is planned with inspections, utilities, access, and finish work in mind.

ADU drawings and permits should not be separated from the real site conditions. BBC ADU helps homeowners connect the plan set to access, utilities, existing structures, garage condition, drainage, kitchens, bathrooms, inspections, and the construction sequence so the drawing process starts with practical information.

Permit coordination needs address-specific review

California ADU law gives homeowners broad options, but the property still needs the right local review. The address, jurisdiction, zoning, hillside or fire conditions, utility requirements, and existing home can all affect the path. A clear construction scope helps the homeowner and the design professionals avoid drawings that look good on paper but leave major trade questions unresolved.

• Scope clarity before drawings move too far
• Coordination with the right design and permit professionals
• Construction planning around inspections and trade sequencing
• Support from first site review through final details
• Address, jurisdiction, zoning, and permit path
• Construction scope aligned with drawings
• Utility, inspection, and sequencing questions reviewed early

What a homeowner should understand before moving forward

Before drawings move too far, the homeowner should know which ADU type is being planned, where it will sit, how utilities may connect, what existing conditions need more review, and which decisions will affect permits, pricing, and construction.

1. Site conversationTalk through the property, intended use, budget direction, and timing.
2. Property reviewLook at access, structure, utilities, drainage, layout, and the work area.
