“Rummy drove this to the end for the permit to finally be granted to us. The design itself is beautiful. She is talented, honest, and dependable.”
Leah T. · ADU permit and design
“Rummy walked us through multiple different design ideas and came out to the property to understand the current layout, landscape, and how the sun hit our home.”
Blair S. · ADU design
“Rummy designed 1700 square feet of new space for us that considered rental income, views, multifamily living, aging in place, and privacy.”

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 and 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.
Site and Rule Review
Before final drawings, we review setbacks, easements, utilities, fire rules, coastal limits, and the size allowed under California law.
Coordinated Design Build Knowledge
IL Total Design and Build handles architecture and construction. This keeps the architect and contractor working toward the same goal and helps avoid costly changes.

Custom ADU Plans
Your new unit should match your goals and budget. We create a practical layout that feels comfortable, natural, and ready for daily use.
Permit Drawings
Our architect prepares clear city documents so engineers and the contractor understand the work before building starts.
Feasibility Review
We review zoning, setbacks, utilities, height limits, and existing structures. This can save time during the permitting process.
Detached Unit Architecture
A detached ADU can serve as a rental, granny flat, or private home for family. We consider placement, privacy, and utilities.
Attached Unit Design
An attached ADU keeps its own entrance and living areas. It can work well when the yard is small.
Garage Conversion Plans
We turn an existing garage into a comfortable living area. The drawings may cover insulation, plumbing, electrical work, and fire separation.
ADU Over Garage Design
This option adds housing while keeping more of the yard open. The architect reviews support, stairs, privacy, height, and access.
Junior Unit Plans
A junior ADU creates a smaller independent unit inside an existing home. We focus on a simple layout and permit-ready documents.
Interior Planning
We arrange kitchens, bathrooms, storage, bedrooms, and circulation so the ADU uses every square foot well.
Our ADU Building Process
Move from property review to permit-ready architecture with a clear sequence.
Property Consultation and 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.
Feasibility and Architectural Design
We confirm the possible size, layout, and main site limits before creating a custom ADU design made for your property and goals.
Permit Plans and City Submittal
After you approve the design, we prepare the permit package and coordinate the documents needed for city review and approval.
Construction Planning
After permit approval, IL Total Design and Build can prepare the ADU project for construction without making you start over with a new contractor.
One Team From the First Sketch Forward
Separate architects, engineers, and contractors can make communication harder. IL Total Design and Build keeps the main work with one coordinated team.
Each ADU is shaped around the site, the home, and the people who will use it. You receive simple updates as the work moves forward.
