Custom ADU Builidng That Adds Space

At 616 Custom Construction, we build custom ADUs that add real living space, improve property value, and make better use of your lot. An accessory dwelling unit, or ADU, is a smaller home built on the same property as your main house. Homeowners use ADUs for many reasons, including housing for family members, guest space, rental income, home offices, or aging-in-place solutions. We help you turn that idea into a finished, durable structure that fits your property and your goals.

We handle ADU building as a full construction service. That means we guide the project from planning and site preparation through final construction. Our team works closely with you to understand how the space will be used, what size and layout make sense, and how the new structure should look alongside your existing home. Every property is different, so we focus on practical design, quality workmanship, and a smooth building process.

What is included in our ADU building service

Our ADU building service can cover every major phase of the project. Depending on the property and scope, this may include:

• Site review and project planning
• Detached ADU construction
• Attached ADU additions
• Garage conversion ADUs
• Interior and exterior framing
• Concrete and foundation work
• Roofing, siding, and exterior finishes
• Doors, windows, and insulation
• Electrical, plumbing, and HVAC coordination
• Kitchen and bathroom build-outs
• Flooring, drywall, trim, and paint
• Accessibility features for long-term living
• Utility connections and drainage considerations
• Final detailing and move-in-ready finishing work

We build ADUs to be comfortable, efficient, and code-conscious. Whether you want a compact backyard cottage or a fully equipped in-law suite, we make sure the space is functional and built to last.

Common types of ADUs we build

We work on several types of accessory dwelling unit projects. A detached ADU is a separate structure, often built in the backyard, that gives the most privacy and flexibility. An attached ADU connects to the main home through an addition or converted section of the structure. A garage conversion ADU can be a smart option when you want to turn existing square footage into usable living space. We also help homeowners who want a custom small-home style layout with a kitchen, bath, sleeping area, and living room all designed for everyday comfort.

Each type of ADU has different building requirements, site limitations, and utility needs. We walk you through those details early so you can make smart decisions about budget, size, access, and long-term use.

How our ADU building process works

We start by talking with you about your vision, your property, and how you plan to use the ADU. Some clients want extra room for parents or adult children. Others want private guest housing or an income-producing rental unit. Once we understand the purpose of the project, we help shape the plan around the right layout, materials, and construction approach.

From there, we evaluate the build area, site access, grade, setbacks, drainage, and utility needs. ADU construction often requires careful coordination because the new structure has to work with the existing property. We plan for practical items like foundation placement, stormwater flow, service lines, pathways, privacy, and how the finished building will look from the street and backyard.

During construction, we focus on quality at every stage. That includes solid framing, weather protection, proper installation of windows and doors, interior finishing, and attention to the details that make the space feel complete. We keep the jobsite organized and communicate clearly so you know what is happening and what comes next.

Benefits of building an ADU

An ADU can solve several problems at once. It adds livable square footage without the need to move. It can create more independence for family members while keeping them close. It may provide rental income and increase the usefulness of your property. It can also give you a flexible space that changes with your needs over time.

Many homeowners also choose ADU construction because it can be more practical than a major full-home addition. A well-built accessory dwelling unit gives you separate living space, more privacy, and strong long-term value. When designed well, it feels like a natural extension of the property rather than an afterthought.

Built for function, comfort, and curb appeal

We believe an ADU should do more than meet basic requirements. It should be comfortable to live in, easy to maintain, and visually consistent with the rest of the property. We pay attention to the details that matter, including storage, natural light, efficient layouts, durable exterior materials, and finishes that hold up to daily use. The goal is to build a space that looks great and works well for years.

We also understand that ADU projects are a major investment. That is why we focus on honest communication, reliable scheduling, and workmanship you can trust. As a hands-on construction company, we take pride in building spaces that homeowners feel good about using every day.
