BOOK A CONSULTADU Questions From San Diego Homeowners
Thinking about building an ADU? Here are simple answers about design, permits, construction, garage conversions, and how IL Total Design & Build helps from start to finish.
What does IL Total Design & Build help with?
We help San Diego homeowners plan, design, permit, and build ADUs. Our team handles the project from the first property review to final construction, so you do not have to manage separate designers, permit help, and builders.
What types of ADUs do you build?
We help with detached ADUs, garage conversion ADUs, custom ADUs, granny flats, guest houses, backyard homes, and ADUs over garages. Every ADU is planned around your lot, your goals, and how you want to use the space.
Can you help me know if my property can support an ADU?
Yes. We start by reviewing your property, existing structures, access, layout, and goals. This helps us explain what may be possible before you spend time and money moving deeper into the ADU process.
Do you handle ADU permits in San Diego?
Yes. Permit support is part of our process. We help prepare the plans, coordinate the permit steps, and guide your ADU project through the required reviews before construction begins.
Can you convert my garage into an ADU?
Yes. A garage conversion can be a smart way to add living space using an existing structure. We can help turn a garage into a functional ADU, guest space, rental unit, home office, or bedroom layout when the property allows it.
Are your ADUs prebuilt or custom?
Our ADUs are custom planned for your property. We do not just drop a standard box in your yard. The goal is to design and build an ADU that fits your lot, your main home, and the way the space will be used.
How long does an ADU project take?
The timeline depends on the property, design, permit review, and construction scope. During your consultation, we can explain the main steps and give you a more realistic timeline based on your specific ADU project.
How much does it cost to build an ADU in San Diego?
ADU cost depends on size, design, site conditions, utilities, finishes, and whether it is detached, attached, or a garage conversion. We start with a property review so you can understand the likely budget before moving forward.
What makes IL Total Design & Build different?
You work with one local team for design, permits, and construction. That means fewer handoffs, clearer communication, and one group responsible for helping your ADU move from the first idea to the final walkthrough.
