ADU Plans
Make more of the property you already have.
Whether you’re creating a place for family, adding a rental unit, or planning for greater flexibility in the future, we help turn your ADU idea into a thoughtful design and clear plans for permitting and construction.
A Small Home Still Needs a Complete Plan
Start With the Right Constraints
ADU requirements vary by location, property, and project type. We begin by understanding the site, the existing home, and the key requirements that may shape what you can build.
Make Every Square Foot Count
Limited space makes good planning especially important. We help organize the layout around privacy, storage, natural light, circulation, and the way the space will actually be used.
Think Beyond the Floor Plan
Access, parking, utilities, stairs, windows, structure, and the relationship to the primary home can all influence an ADU design. Working through these considerations early helps create a clearer path toward construction.

How It Works
Understand the Project
We start with the property address, the type of ADU you’re considering, your goals for the space, and any plans, measurements, sketches, or photos you already have.
Review the Starting Conditions
For projects involving an existing home, we determine what needs to be measured and documented. For detached ADUs, we review the available site information and the constraints that may affect the location and size.
Design and Refine
We develop the layout and major design elements, then work through the decisions with you until the ADU is headed in the right direction.
Prepare the Plans
Once the design is established, we develop the drawings needed to move the project toward permitting and construction. When structural engineering is required, we can coordinate that work as part of the process.
For Builders
We provide practical design and drafting support for basement, attached, detached, and conversion ADUs – helping define the scope, work through project constraints, and prepare clear plans for permitting and construction.
For Homeowners
You don’t need to know exactly what will fit before contacting us. Start with the property address and what you hope the ADU will accomplish, and we’ll help you determine the right next step.
Project-Based Pricing
Because ADUs can range from a relatively straightforward basement conversion to an entirely new detached structure, pricing depends on the project type, existing conditions, size, and required design and drafting work.
Once we understand your project, we’ll provide a clear, project-specific proposal before moving forward.
Timing
Straightforward ADU design and drafting projects can often be completed in approximately 2–4 weeks once we have the information needed to begin. More complex projects may require additional time, and structural engineering and municipal review will have their own timelines.
Frequently Asked Questions
-
ADU requirements vary by city, zoning district, lot, parking, utilities, and project type. Start by sending us the property address and a description of what you have in mind. We can help review the starting constraints and determine the right next step.
-
No. Existing plans are helpful when available, but they aren’t required. For ADUs involving an existing home, we’ll determine what measurements, photos, or other documentation are needed before design begins.
-
The drawings depend on the project, but typically include the plans, elevations, sections, and details needed to communicate the work for permitting and construction. We’ll define the exact scope in your proposal before work begins.
-
Yes. When structural engineering is required, we can coordinate it as part of the project so the engineering and drawing set work together. Engineering fees and timing are separate and will be discussed before that work begins.
