Custom Adu in Orinda

Orinda Custom ADUs

Sophisticated design-build ADUs tailored for Orinda’s distinct hillside and wooded properties.

Whether you are building a modern guest cottage on a steep incline or a discrete in-law suite nestled in the trees, we design ADUs that speak to your property’s unique character. By blending architectural planning and expert construction management, we deliver unparalleled detached homes without the usual remodeling headaches.

Building Backyard Homes in Orinda

Constructing an ADU in Orinda requires a highly specialized touch. Many local properties sit on steep grades or feature striking mid-century architecture that shouldn’t be compromised. Whether the goal is to engineer a cantilevered foundation over a hillside or to tuck a unit neatly into a wooded corner, we start by analyzing the heavy structural engineering required to make it a reality.

Hillside Structural Engineering

Building an ADU on a slope means dealing with complex retaining walls, caissons, and deep pier foundations. Our team identifies these geotechnical realities early, preventing expensive redesigns.

Preserving Mid-Century Aesthetics

Designing an ADU for a mid-century property requires respecting flat rooflines, exposed beams, and natural materials. We design structures that complement, rather than compete with, your iconic home.

Overcoming Access Challenges

Orinda is famous for its steep, winding roads. We strategically sequence the arrival of excavators, concrete trucks, and lumber drops to accommodate your specific driveway safely.

Fire Safety and Wildland Codes

Building in Orinda often means adhering to strict Wildland-Urban Interface (WUI) fire codes. We specify compliant exterior materials, tempered glass, and proper clearances from day one.

ADU Design / Build Process

1. Initial Site Visit: 1 to 1 ½ hrs

Every ADU starts with a vision, and this starts with a walkthrough to see what you have and understand what you want. By listening closely to your goals, vision, questions, and budget, we help you unlock the full potential of your ADU. With so many creative ways to configure compact spaces, whether it is a rental, guest suite, or a small home, it all starts with understanding how you want to live.

Step 1 – What To Expect

On site walkthrough to evaluate the starting point and discuss the overall goals of the project.
We provide a free ballpark construction cost, which will be a significant range.
This ballpark helps us understand if a client’s budget aligns with our estimated construction cost.
To proceed, we sign our preconstruction agreement (PCA), which includes the various services you will need to design and ultimately acquire the building permits.

2. Design & Material Selection: 3 - 4 weeks

Once the vision is clear, the design process brings it to life on paper. From countertops to cabinet layout to lighting, we’ll plan each detail with precision. A thorough design phase is key to staying on budget. Also, it’s often the fun part!

Consultations for all project goals and design considerations.
Some common design goals include careful attention around kitchen and bathroom design, lighting options, fixture selections, as well as exterior hardscape and landscape. The contractor creates an all-inclusive list of all project selections for client review and interaction. This single tool will be used to guide the project to the finish line.

3. Permitting: 2 - 3 months

Once the design is complete, it’s time to submit the plans to the city for approval. Approval time for an ADU can vary, but generally this will take around 2 – 3 months to get approved. The good news is that you can still keep the project moving! While most product selections will have already been considered, this is the time to actually start finalizing selections and shopping for items. Top on that list will often be key components for kitchen and bathroom, flooring, appliances, and fixtures.

4. Construction: 4 - 8 months

Finally, our team begins by carefully protecting your home and the surrounding areas. For attached ADUs, we install dust barriers with zipper doors and run HEPA air filtration to keep the air clean and the rest of your home undisturbed. Floor protection and other precautionary measures are also put in place. A dedicated team and project manager will carry out the work in coordination with the residents, with clear working hours established from the start.

5. Move In!

Upon passing our city final inspection, we will then do a thorough walkthrough, to ensure everything is just right. We will also provide and go over all of your new documentation, including manuals, warranties, etc., as well as provide a long term maintenance plan to help you make sure your ADU stays beautiful for years to come!

FAQ

You Ask We Answer

How long does a custom ADU typically take to build? +

Active construction on a high-end Orinda ADU usually takes 4 to 6 months. Complex hillside engineering and custom architectural details will dictate the exact pace, which we outline in a firm schedule.

Can we attach the ADU to our existing house or garage? +

Yes. If hillside constraints make a detached unit financially impractical, we can design stunning attached ADUs that flow naturally from the existing structure.

Do you handle City of Orinda permits for ADUs? +

Yes. We handle every piece of red tape, dealing directly with the City of Orinda's planning and building departments to secure ADU permits and pass all necessary safety inspections

Can our current electrical and plumbing support an ADU? +

We will perform a full diagnostic of your home’s systems. Hillside utility trenching is complex; we often recommend upgrading the main panel and running a dedicated sub-panel to the new unit.

How do you handle privacy and access during construction? +

We proactively discuss how the construction will impact your routine, utilizing advanced staging techniques to keep the active site separate from your sanctuary.
