Guiding You from Eligibility Through Completion

Designing and building an Accessory Dwelling Unit is a long, complex process. From initial contact to final inspection, most of our ADU projects are completed in under 1 year. Here’s the ADU Design/Build process we follow:


Find Out If You Are Eligible

The first step is to find out if your property qualifies for an ADU. Contact your city or county planning department to find out if you can add an ADU to your property, the maximum square footage allowed, and the property setbacks in place that will influence where you can place an ADU.


Initial Consultation

The next step is a free initial consultation from Backyard Unlimited. During this step, our team will review a satellite view of your address, conduct a rough feasibility analysis, and provide you a ballpark quote.

3D Design

To continue planning your ADU, we will create a 3D design of your ADU. This involves an on-site property visit to take detailed measurements. Once we have those, our designer will create a full 3D model of your ADU, with a round of revisions. If you like the model, we will provide a detailed quote for your project.

  • Cost: $500
  • Time: 2-4 weeks

Drafting & Engineering

The next step is to transform that 3D model into the drafts and engineer-approved drawings we will need for the permitting process. This step includes engineering analysis & stamp, Title 24 energy analysis & certification, and solar design & plans. At the end of this step, you will have a finalized contract with final pricing.

  • Cost: $3,000
  • Time: 8-12 weeks


After the drafts have been completed and the final contract signed, our team will apply for building permits with your local planning office. Each project varies with the amount of time it takes to receive permits, but you can generally plan for 10-16 weeks before we receive approval.

  • Cost: Included in Contract
  • Time: 10-16 weeks


Once we get the permits in hand, we can schedule your installation. Your ADU will arrive in prefabricated sections, which we will assemble and finish. Backyard Unlimited schedules and manages all subcontractors, as well as scheduling all inspections.

  • Cost: Included in Contract
  • Time: 12-20 weeks
