ADU Design Services Include

Site Evaluation & Feasibility Study

3D Modeling & Layout Visualization

See exactly how your ADU will look and function with clear visual models and layout previews.

Pre-Designed Plans (Optional)

For faster turnaround and lower cost, choose from our library of pre-approved layouts, which can be modified to fit your lot.

Permit-Ready Construction Documents

You’ll receive a full set of architectural blueprints, engineering-ready drawings, and documents prepared for submission to your city’s building department.

As-Built Documentation

Update drawings that reflect the actual conditions of a building after construction is completed. These records capture any changes made during the build process and include final dimensions, layouts, and system placements.

Code & Zoning Compliance

We ensure your design follows all local residential codes, state laws, and city-specific requirements for approval.

Coordination With Engineers & Contractors

While we don’t handle construction, we coordinate directly with your builder or engineer to make sure everything lines up, from foundation details to final plans.

Timeline & Permit Guidance

We walk you through the design timeline and help you understand what to expect during the permit approval process.

Our Work Process

Property Review

We look at your lot, zoning, and city rules to see what kind of ADU you can build. Typically, we prepare the as-builts for the existing property and property lot.

ADU Planning

We create a detailed 3D model and a comprehensive set of plans for your new ADU. Our goal is to maximize usability and explore the best options, whether you’re building an addition or converting an existing structure.

Custom Design & Revisions

Depending on the resource and budget, we can use free designs, use a design from our library, or develop any customizable design per your sketches, vision, and inspiration. There are multiple ADU options, and we’ll help you compare them to find the solution that best fits your property, goals, and lifestyle.

Permit-Ready Blueprint

Once we finalise the design and ensure it has everything you need, we prepare the submittal package for our client to get approved for the new ADU construction project.

FAQs

We focus only on ADU design. We don’t build, manage construction, or act as a general contractor. Our job is to deliver clear, code-compliant plans that make building easier for you and your team. We can also offer construction supervision to ensure the ADUs are built per the plans.
Yes. They are ready to hand off to any licensed builder. We’ll even coordinate with your contractor or engineer if needed to keep everything on track. WE provide multiple file types, making it user-friendly and easy to use by different stakeholders.
Not necessarily. In most cases, hiring an architect isn’t required, it’s more a matter of preference. It’s always recommended to work with the same architect for consistency if you plan to expand. Acting as the owner or the owner’s representative can help you get exactly what you want, often at a more affordable cost.
Most projects take 3–6 weeks, depending on the complexity and number of revisions. Faster if you're using a pre-designed ADU plan.
Adding an ADU is an important decision. That may serve you as a granny flat, a smaller single-family home, a business studio, or you can also make it your primary housing, while generating rental income on the main house rental through Airbnb or similar services. It may help you make a better return on investment and increase the value of your real estate assets.
