Lafayette Custom ADUs

A dedicated design-build team constructing Lafayette ADUs with structural precision and architectural style.

Whether building a detached pool house for guests or a secondary suite for aging parents, we tailor our ADU designs to the exact specifications of your property. Our integrated approach ensures that the design, permitting, and construction phases flow together flawlessly, providing you with a beautiful, functional independent living space.

Constructing Accessory Dwellings in Lafayette

Lafayette properties present fantastic opportunities for ADUs, but building them comes with distinct logistical puzzles. Placing a unit in a large backyard requires perfectly graded foundations and long utility runs, while navigating city setback regulations requires meticulous planning. We evaluate your home’s specific lot geometry first, ensuring our aesthetic plans are grounded in structural and legal reality.

Property Lines and Easements

Even on generous Lafayette lots, city setbacks dictate the buildable envelope. We conduct a thorough zoning review early in the design process to ensure your desired ADU placement is legally permissible.

Utility Trenching and Connections

Connecting a backyard ADU to the main house’s water and sewer requires significant trenching. We map out the most efficient, least destructive path across your landscaping to tie into the grid.

Engineering Flawless Foundations

A detached ADU requires its own solid base. We conduct thorough soil evaluations and precise grading to ensure the new concrete slab or crawlspace is perfectly stable and level.

Site Management and Excavation

Preparing the ground for an ADU requires heavy machinery. By carefully coordinating the logistics of excavation and concrete pours, we ensure that the process is minimally invasive to your property.

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? +

Most of our Lafayette ADU projects wrap up within 4 to 6 months of active labor. We provide a highly detailed timeline before demo begins so you know exactly what to expect week by week.

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

Yes, we frequently build attached ADUs and execute garage conversions if that is the best use of your property's footprint.

Do you handle City of Lafayette permits for ADUs? +

Absolutely. From the first planning commission meeting to the final inspector's signature, we manage the entire permitting process with the City of Lafayette on your behalf.

Can our current electrical and plumbing support an ADU? +

It is very common for a new ADU to require an electrical heavy-up. We will evaluate your current panel and run the necessary dedicated circuits and plumbing lines to support a fully independent home.

How do you handle privacy and access during construction? +

We establish a dedicated construction pathway—usually along a side yard—and erect temporary fencing to ensure our crew remains isolated from your primary living space.
