Custom ADU Design for San Diego Properties
Every ADU starts with a layout that fits the lot, the home, and the people who will use it.
IL Total Design & Build helps homeowners create an accessory dwelling unit for family housing, rental income, or long-term flexibility. Our architect reviews access, utilities, privacy, height limits, and local regulation before drawings begin.
We work on detached, attached, junior, and multi-family ADUs. We guide the ADU project from the first review through approval.
Architecture, Permits, and Construction Under One Roof
A well-planned ADU should feel like part of your home. Good architecture considers sunlight, privacy, access, and daily use.
Before final drawings, we review setbacks, easements, utilities, fire rules, coastal limits, and the size allowed under California law.
IL Total Design & Build handles architecture and construction. This keeps the architect and contractor working toward the same goal and helps avoid costly changes.
Our Services
Our ADU Building Process
Property Consultation & Site Review
We discuss your goals, how you plan to use the ADU, and what may fit on your property. Our architect also reviews the main site conditions.
We review lot coverage, easements, grading, fire access, utilities, and coastal requirements. Most first meetings take about 30 to 45 minutes.

We confirm the possible size, layout, and main site limits before creating a custom ADU design made for your property and goals.
The design may include floor plans, exterior views, rooflines, room layouts, entrances, windows, and three-dimensional images.
