The first step to transform your property
The process of planning and building an Accessory Dwelling Unit (ADU) begins with a feasibility study. Our team of experts will carefully evaluate your property, local laws, and overall goals to determine the best potential placements and sizes of your future ADU, working to highlight the unique opportunities that your property can provide.

Discovering the potential

Building an ADU can be life-changing; make sure you start the process with an accurate understanding of what to expect.
Our feasibility study provides options for your property, setting expectations and creating a smooth transition into the design phase. We gather all of the necessary information before anything is set in stone, avoiding last-minute calls of “Can I even place an ADU there?” or “Wait- is this even in budget?”

Frequently asked questions
A feasibility study is the only way to bring all the key questions and potential challenges to light before moving forward.Think of the feasibility study as Phase 1 of your ADU journey. It’s where we uncover zoning restrictions, site limitations, cost considerations, and any surprises that could impact your project. Instead of running into roadblocks later, you get clear answers upfront, all in one comprehensive, easy-to-understand document.It’s not just a smart step, it’s an essential one. The feasibility study gives you the clarity and confidence you need to move forward with your ADU the right way.
While all residential properties in California are entitled to build at least one Accessory Dwelling Unit (ADU) of up to 800 square feet, there are rare cases, such as those involving environmentally sensitive lands, where certain limitations may apply due to safety or regulatory concerns.
That said, there’s no need to worry. Once you purchase a feasibility study through our website, you’ll submit your property details and proposed ADU scope. Within 24 hours, one of our experts will reach out to schedule a one-on-one consultation. During that call, we’ll review your information and provide an initial assessment of your project’s viability.
In the unlikely event that your concept isn’t feasible, we’ll either issue a full refund or work with you to explore alternative ADU options that better suit your property. If it is viable, we’ll move forward with in-depth research and deliver a comprehensive feasibility study—complete with a personalized walkthrough from our team.
Questions our Feasibility Study can answer

If you’re in California- chances are, yes! The possibility of building an ADU on your property depends on local zoning laws, regulations, and property restrictions.
Working with ADU Geeks means we’ll conduct the research for you. Let us handle the complicated stuff so you can focus on what matters!
With the many variables that go into building an ADU, it can be difficult to determine the potential cost. For example, converting an average 400sf (2-car) garage can cost between $105k-$125k.
Every ADU is different, and we’re committed to providing accurate information. Through our feasibility study, you’ll receive approximate costs for each option to help you in your planning and budgeting process.
From the beginning of the design phase to getting keys in hand for a completed ADU, the average ADU project timeline is around 9-14 months. Keep in mind that timelines can vary depending on terrain, how many units you plan to build, permitting turnaround time, and other factors.
Our feasibility studies break down an estimated timeline based on your property and goals, showing expected due dates and other important milestones.
Typically, 2-3 ADUs are allowed on a residential property in California – but what if we told you that certain properties were allowed to have 20+? Depending on your location, existing structures, and state-level allowances, the total number of ADUs that you’re allowed can change drastically. We’ve worked on projects big and small!
Our feasibility study investigates so you don’t have to. We’ll explore multiple options throughout the process so you can choose what’s best for you and your property.
