Danville Custom ADUs

A master design-build team creating stunning ADUs tailored to your Danville lifestyle.

Whether you are building a backyard cottage near historic downtown or a luxury guest house on a Blackhawk estate, we design and build ADUs that perfectly align with your home’s architecture. Our single-source accountability ensures that your project transitions smoothly from structural engineering to the final coat of paint.

Building Secondary Suites in Danville

Danville’s housing market is incredibly diverse. Building an ADU behind a historic downtown home requires a delicate touch to navigate tight lot lines and preserve character. Conversely, constructing an ADU on a Blackhawk property often focuses on maximizing luxury footprints and adhering to strict community guidelines. We tailor our structural and aesthetic approach entirely to the era and style of your specific residence.

Engineering New Foundations

A solid ADU requires a flawless foundation. We coordinate soil testing and structural engineering to ensure the new footings properly support the structure, whether it’s a slab or raised floor.

Navigating Property Restrictions

Building a detached unit means dealing with local lot coverage maximums and setback rules. We conduct a thorough feasibility study during the conceptual phase so there are no legal surprises later.

Gated Community Logistics

Working in Danville often means adhering to strict HOA guidelines and navigating gated security. We expertly manage these logistical constraints, coordinating concrete trucks and deliveries to ensure strict compliance.

Coordinating Utility Tie-Ins

We manage the complex trenching required to connect your new ADU to the main house’s water, sewer, and electrical grid, ensuring minimal disruption to your existing yard.

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!
