What Is a Custom-Built ADU?
An accessory dwelling unit, or ADU, is a separate living space built on the same lot as your main home. It has its own kitchen, bathroom, and living area, which makes it fully functional as an independent unit. A custom-built ADU means the design is planned around your property, your goals, and your lifestyle instead of using a fixed template.
Some homeowners want a detached ADU in the backyard. Others prefer an attached unit, a garage conversion, or a second-story addition. With a custom approach, you decide the size, layout, materials, and finishes. This flexibility is one of the biggest reasons homeowners in Lafayette choose a custom home design over a standard prefab model.
Why Homeowners in Lafayette Are Building ADUs
California has become one of the most ADU-friendly states in the country. Relaxed rules and updated regulations have made it easier for homeowners to add these units to their property. In an area like Lafayette, where property values are high and space is valuable, an ADU offers real benefits.
A well-built ADU can create rental income, giving you a steady monthly return. It can also provide comfortable housing for aging parents, adult children, or guests. Many people use ADUs as private offices, studios, or gym spaces. On top of daily use, an ADU can increase the overall value of your property, which is helpful if you ever plan to sell.
Because these units serve so many purposes, working with a skilled custom-built ADU contractor ensures your unit is built to match your specific plans.
Benefits of Hiring a Custom Built ADU Contractor
Building an ADU is a big project, and doing it correctly requires more than basic construction skills. A professional contractor brings design knowledge, permit experience, and project management to the table.
When you hire an experienced team, you avoid many common problems. Permit delays, design mistakes, and budget surprises are far less likely when the work is planned properly from the start. A good contractor also understands local building codes, setback rules, and utility requirements, which are important in Lafayette.
Most importantly, a custom contractor listens to your goals. Instead of forcing your project into a fixed plan, the design is shaped around your property and your needs. This leads to a smoother process and a finished unit you will truly enjoy.
Our ADU Construction Process
At RWB Construction, we follow a clear and simple process so you always know what is happening at each stage.
First, we meet with you to understand your vision, budget, and timeline. This helps us plan a unit that fits your property and lifestyle. Next, our design team creates a custom plan, including layout, materials, and finishes. We make sure everything is approved before any work begins.
After planning, we handle the permits and paperwork required for your ADU. Permits are an important part of any ADU project in Lafayette, and we manage this step to keep things organized. Once approvals are ready, our construction team begins building with a strong focus on quality, safety, and timelines.
Before we hand over your finished ADU, we complete a full inspection to make sure every detail meets our standards. Our goal is to deliver a space that is comfortable, durable, and ready to use.
Types of ADUs We Build
Every property is different, so we offer several ADU options based on your space and goals. Some homeowners choose a detached ADU, which is a standalone unit separate from the main house. Others prefer an attached ADU that connects to the existing home.
We also build garage conversion ADUs, which turn an existing garage into a functional living space. For homes with limited yard space, a second-story or above-garage ADU can be a smart solution. No matter the type, our team designs each unit to match your property and your needs.

Planning Your ADU Budget and Timeline
Every ADU project is unique, so costs and timelines depend on several factors. The size of the unit, the type of ADU, materials, finishes, and site conditions all play a role. Permit approvals and inspections also affect the overall timeline.
A smaller garage conversion may take less time and cost less than a fully detached custom unit. During our first meeting, we review your goals and provide a clear estimate based on your specific project. This helps you plan with confidence and avoid unexpected costs later. Our team works hard to keep your project on schedule and within your budget.
