Property-specific ADU planning
Design around a homeowner goal
Custom ADU
Develop a site-specific ADU direction around the homeowner brief, property conditions, and required professional work.
How the scope is defined
Turn a service name into a buildable, written project.
The same service can involve very different work on two properties. These three stages keep the assumptions, responsibilities, and decision points visible.
01 · Existing conditions
Start with the property and intended use
Review the address, available records, existing structures, access, utilities, and the outcome the homeowner wants.
- Property identity and available records
- Existing conditions and known constraints
- Desired use, capacity, and priorities
02 · Coordinated scope
Define what the project actually includes
Translate the selected service into a property-specific scope, with the disciplines and approvals that the project requires.
- Design and engineering inputs as required
- Agency, utility, and permit coordination
- Selections, responsibilities, and exclusions
03 · Written decisions
Confirm before downstream work begins
Document the verified assumptions, unresolved items, deliverables, price, and schedule before relying on the scope.
- Verified inputs and remaining unknowns
- Project-specific proposal and documents
- Decision gates, changes, and acceptance
The useful next decision
Confirm the property before committing to custom adu.
A preliminary property review can identify available records, missing information, map corrections, and an early fit direction. Professional review still controls final design and approvals.
Have a specific property or question?
Share the address and intended use so the conversation starts with the correct context.
