How It Works

FREE 30-Minute Consultation

We offer a free initial consultation and preliminary feasibility study to make sure your property is eligible for a garage conversion, and to answer any questions you have regarding planning, designing, and building a garage conversion ADU.

Design & Construction Documents

Our ADU Designers are experts in the ADU laws and California building codes, and focus solely on designing beautiful small homes. We work collaboratively with you to make sure your new ADU design meets all your lifestyle needs.

Once you are 100% satisfied with the design, we generate the construction documents (i.e. - blueprints). This is where we add all the construction details and building code requirements and create a set of construction documents which will be used to build you new ADU.

Permit Approvals

We handle all the permit approval paperwork and expedite your project through the local building department. We have processed over 200 garage conversion plans throughout California, and have the knowledge and experience needed to get your project permitted and approved fast.

What Our Clients Are Saying


Josh - Burbank

We had a TERRIFIC experience with Charlie at CALI ADU. He was efficient, communicative and provided us with great blueprints for our garage conversion. Whenever the city had corrections, he was right on top of it responding and resubmitting. Highly recommend working with him.

Madeline - Manhattan Beach

I am so happy we chose CALI ADU to design and build our garage ADU. Charlie Melvin is exactly as easy to work with as he seems when you first meet him.

The consistent communication is so appreciated, and the outstanding quality of their work is exactly like the pictures we saw in the CALI ADU online portfolio.

Kevin - North Hollywood

We worked with Charlie from CALI ADU, who we engaged to draft our ADU. Initially, we worked with him to draft the ideas, but ultimately determined he was the best person to carry out the work. Charlie is professional, and he was always accessible when we had questions. He is adaptable and patient with changes. My wife and I highly recommend Charlie.

100% Money-Back Guarantee

You'll love your ADU design and we'll get it permitted. Guaranteed!

ADU Plan Approval Guarantee

All of our Garage Conversion Plans and Permit Packages come with two money-back guarantees. If you don't love the design, or we can't get it approved, we'll give you a 100% refund.

The "I Love My ADU Design" 100% Money Back Design Guarantee

If you don't absolutely love the design and floor plan of your new ADU, just let us know, and we'll refund you every dollar you've paid. No questions asked and no hard feelings.

Assuming you love your new ADU design (and we're sure you will), we move forward with creating all the technical construction documents needed to obtain a building permit. That is where our 2nd 100% money back guarantee kicks in.

Our "Permit Approval" Guarantee

We are ADU experts and know what is allowed, and what is not, with the ADU laws and building codes. We're 100% confident our designs and plans will pass all required plan checks. If they don't pass, we will refund every dollar you have paid including all design fees and City/County plan check fees.

Pretty incredible, right? We offer these two guarantees because we understand the ADU process and know what it takes to get an ADU approved. We don't waste time and money designing and planning projects that wont be approved.
