Discuss your ideas, photos, and project priorities by phone or video. Final measurements, site conditions, and scope may require an on-site visit.
What to share for your
Rancho Santa Fe project
- Share the property address, a basic site sketch, and photos of the proposed ADU or garage area.
- Describe who will use the space and the rooms, accessibility features, and privacy you want.
- Gather any existing plans and information about utility locations, sewer or septic service, and access.
Decisions to discuss
- Compare converting existing space with building a new structure.
- Identify site access, utility connections, grading, and design work that belong in the budget.
- Confirm the property-specific approval path before treating a concept as a buildable plan.
Can a virtual estimate confirm ADU approval?
No. A virtual estimate is a useful first discussion of scope and budget. Feasibility, design, utility capacity, and required approvals need review for the specific property.
