Add Rentable, Flexible Space to Your Redmond Home

ADU Construction in Redmond, WA

Redmond is a city of growing families and busy professionals, and both groups have something in common: they need flexible space and they own lots that can provide it. An accessory dwelling unit turns a workable Redmond backyard or an underused garage into a second, self-contained residence, a rental unit in one of the region's strongest rental markets, an independent home for parents or adult children, or a quiet office removed from the main house. At AVEAD Construction, we design and build ADUs for homeowners across Redmond, handling the whole project, from the first feasibility conversation through design, permitting, and construction, with one accountable team.

What makes that possible is our design-build model. The same team that designs your ADU also prices and builds it, which closes the gap that trips up so many projects, where a designer draws something a separate contractor then struggles to build within budget. With us, your Redmond ADU is grounded in reality from the first sketch, and there is never any confusion about who is responsible for the result.

What an ADU is, and why it works in Redmond

An accessory dwelling unit is a second, independent living space on the same lot as your primary home, with its own entrance, kitchen, and bathroom. Unlike a room addition, it functions as a genuinely separate residence, which is what gives it such range: the same unit can house a family member now and a paying tenant later.

Redmond is close to ideal for ADUs. A large share of its housing is solid builder-grade construction on suburban lots that comfortably accommodate a detached unit or a garage conversion. Rental demand is consistently strong, driven in part by the area's concentration of employers and professionals, so an income unit here has real earning power. And Redmond has actively supported ADU development, which makes building one more straightforward than it once was.

The types of ADUs we build in Redmond

There is no single right ADU, the best choice depends on your lot, your budget, and your goals. We build the full range, and part of our early work with you is landing on the form that fits your Redmond property.

Attached ADUs (AADU). An attached unit shares a wall with your existing home while keeping its own entrance, a good fit where a freestanding structure is impractical, and often more economical because it ties into the main home's systems.

Detached ADUs (DADU). A standalone backyard cottage delivers the most privacy and flexibility, and Redmond's suburban lots often have the room for one. A well-built DADU works like a small home in its own right and tends to add the most standalone value. For a ground-up detached build, our work overlaps with our custom home building expertise.

In-law and multigenerational ADUs. Many Redmond families build to keep loved ones close, providing aging parents or adult children a comfortable, independent home on the same property while everyone keeps their own space.

Rental and income ADUs. With Redmond's strong rental demand, an income-focused unit can be a genuinely smart investment. We design rental-ready ADUs that attract quality tenants and hold up over years of use, adding steady income and resale value together.

Garage-to-ADU conversions. Converting an underused garage is often the most cost-effective route to a second unit, since much of the structure already exists. We turn Redmond garages into comfortable, code-compliant living space for rental, guests, or remote work.

Custom ADU design and build. For a particular vision or an unusual lot, we design and build a fully customized ADU from concept through completion, tailored to your Redmond property and grounded in what is buildable because we handle both sides.

If your goal is specifically to convert a lower level into living space, that work belongs with our basement remodeling service, and we will point you the right way.

Why Redmond homeowners build ADUs

The motivations here tend to be practical. Rental income is a big one, given the area's steady demand a well-placed unit can meaningfully offset a mortgage or build long-term wealth. Multigenerational living is another, letting families support aging parents or give adult children a foothold without anyone sacrificing independence. And with so many people working from home, a dedicated ADU as a quiet, separate office or studio has become a genuine draw.

Underlying all of these is value. An ADU adds real, usable square footage, and a quality, well-integrated unit is a strong asset at resale in a market as active as Redmond's. You can read more about how quality construction adds home value. The key is quality and integration, a well-built unit lifts a property, while a poorly executed one can drag it down.

ADU rules and permitting in Redmond

ADUs are among the most regulated residential projects, because you are adding an independent dwelling to your lot. Beyond building, plumbing, and electrical permits, there are zoning considerations, setbacks, unit size, height, and lot coverage, that depend on your specific property. Getting these right during design is essential, because a plan that does not meet them will not be approved.

Encouragingly, the rules have moved in homeowners' favor, with Washington State encouraging ADU development and Redmond updating its requirements to make units easier to build. We track the city's current standards and design your ADU to be approvable from the start. You can read more about how additions and ADUs are permitted and how permitting differs across Eastside cities.

Best of all, we handle the entire process for you, applications, structural engineering, and the inspections during construction, coordinating with Redmond's building department so nothing stalls. Complete, correct submittals move through far more smoothly, and that is what our local experience provides.

ADU, addition, or basement conversion, which is right for you?

Homeowners often begin unsure which project fits their goal. The distinction is about independence and where the new space lives. An ADU is a separate, self-contained unit with its own kitchen and entrance. A home addition expands your existing house as one connected residence, right when you need a larger suite or another bedroom rather than a separate dwelling. And a basement conversion turns lower-level space into livable rooms or, with a full kitchen and entrance, a lower-level unit.

Because we handle all of these, our guidance is honest rather than aimed at one service. If you are weighing options, our FAQ on whether to remodel or build an addition is a helpful starting point, and a consultation will quickly clarify the right path for your Redmond home.

Designing an ADU for your Redmond property

A well-designed ADU never looks tacked on. It should relate to the main home in its rooflines, materials, and detailing, and sit on the lot with intention. Good design also squeezes the most from a compact footprint through efficient layouts, so a small unit feels open rather than cramped, and it protects privacy for both households by placing entrances, windows, and outdoor spaces thoughtfully.

On Redmond's suburban lots, siting a detached unit well makes a real difference to privacy, light, and how the yard feels. Throughout design, our 3D renderings let you see and refine the finished ADU before construction begins, so you are confident in the outcome. This is central to our design-build approach, and it is what keeps costly changes from cropping up mid-build.

What a Redmond ADU costs, and the return

Cost comes down to the type of unit, its size, the finishes, and your site. A garage conversion sits toward the lower end, since much of the structure exists, while a ground-up detached cottage with new foundation, framing, and utilities is a larger investment. Rather than a vague number, we provide a transparent, itemized estimate with no material markups and present options to fit your budget. You can read more about what affects construction cost.

The return is what makes an ADU stand out. Unlike most improvements, it can actively earn, through rent or by meeting a family need, while adding resale value at the same time. In Redmond's strong market, that combination makes an ADU one of the more financially sensible projects a homeowner can take on, and we are glad to walk through the numbers candidly during your consultation.

How long a Redmond ADU takes

Because an ADU adds new structure, it is a larger project, generally measured in months rather than weeks. That timeline includes a design and engineering phase, a permitting period, and construction, with the exact length depending on the unit's type and complexity. A garage conversion moves faster than a ground-up detached cottage with its own foundation and utilities.

The scope is comparable to a home addition, so our guide to how long a home addition takes is a useful reference. Whatever the project, we build a realistic schedule into the plan from the start and keep you informed throughout, so a bigger project never feels open-ended.

Living in your home during construction

A common question is whether you can stay put while your ADU is built. Usually, yes. Because an ADU is a separate structure or a contained conversion, much of the work happens alongside your existing living space rather than inside it, so daily life continues with far less disruption than a whole-home remodel would bring. We keep the jobsite clean, safe, and organized, protect your property, and are upfront about the more involved stages, such as utility connections, so you can plan around them.

Our Redmond ADU process

Every ADU we build follows a clear, structured path. It begins with a consultation and on-site assessment, where we learn your goals and evaluate what your lot and the city's rules allow. From there we develop the design, with custom layouts and 3D renderings you can refine before anything is built, and provide a transparent, itemized estimate. Next we handle preparation, finalizing plans, securing materials, and managing permits and engineering, so construction begins ready to go. Our team then builds each phase with a dedicated project manager and consistent updates, and we finish with a detailed walkthrough before handing over your completed ADU, backed by our five-year workmanship warranty.
