ADUs & DADUs in Edmonds, WA
Your Edmonds home is where your life is rooted — the neighbors you know, the schools your kids attend, the community you have built over the years. But what happens when the house no longer fits your life? Whether your family is growing, your parents need a place nearby, or rising housing costs are squeezing your budget, you do not have to move to find a solution. Accessory dwelling units (ADUs) and detached accessory dwelling units (DADUs) give Edmonds homeowners a way to add space, generate income, and future-proof their property — without giving up the neighborhood they love.

With years of experience helping homeowners navigate permits, zoning, and construction, we handle every step of your ADU project from the first conversation to the final walkthrough. This page answers the most common questions Edmonds homeowners have about ADU costs, timelines, permits, and design options.
ADU & DADU Builders in Edmonds, WA: Solve Space Problems Without Moving
Many Edmonds homeowners find themselves stuck between two hard choices: move to a bigger home at today’s prices, or squeeze into a space that no longer works. Neither option feels right. The good news is there is a third path.
“Our family is growing but we love our Edmonds neighborhood.”
“We want rental income but we are not ready to buy another property.”
“My parents need a place close to us, but everyone needs their own space.”
If any of these sound familiar, an ADU or DADU may be the solution. These flexible housing additions include backyard cottages, detached studios, in-law suites, and garage conversion apartments. They work on a wide range of Edmonds properties — from the tree-lined streets of Edmonds Bowl and Perrinville to the quieter lots in Westgate, Seaview, and Five Corners.
MacCoy Home Solutions manages every part of the process: design, permits, construction, and project management — so you never have to coordinate multiple contractors or wonder where your project stands.
Common ADU & Housing Problems We Help Edmonds Homeowners Solve
Most homeowners start searching for ADU builders because they have a specific pain point. Below are the situations we hear most often — and how we help.
"We Need More Space But Do Not Want to Move"
Edmonds is a desirable community, and for good reason — waterfront access, strong schools, and a tight-knit small-city feel. Moving out to get more space means leaving all of that behind, plus paying today’s elevated home prices and higher mortgage rates. A backyard cottage or garage conversion ADU lets your family expand without giving up the address you love. MacCoy designs custom ADUs tailored to your property layout, your family’s lifestyle, and your long-term goals.
"My Parents Need to Live Close to Us"
Multi-generational housing demand is growing across the Pacific Northwest, and Edmonds families are no exception. A detached ADU or attached in-law suite gives aging parents their own private space — full kitchen, separate entrance, their own living area — while keeping them just steps away when they need help. MacCoy designs safe, accessible living spaces with features like single-level layouts, wider doorways, and step-free entrances for aging family members.
"Can My Property Generate Rental Income?"
With rental demand strong across the Edmonds and North King County area, a well-designed ADU can generate meaningful monthly income. Many homeowners use a backyard rental unit to offset their mortgage, fund retirement, or build long-term wealth. ADU rentals are legal under Washington state and Edmonds city regulations when properly permitted — and MacCoy handles the entire permitting process to make sure your new unit is code-compliant and rentable from day one.
"My Backyard Is Just Wasted Space"
Many Edmonds properties — especially homes built between the 1950s and 1990s — sit on generous lots that are largely underused. A detached DADU transforms that unused yard into a high-value living space that increases both your property’s worth and its functionality. Whether you envision a private guest suite, a creative studio, or a full rental cottage, MacCoy can design a DADU that maximizes your property without overwhelming it.
"I Do Not Understand ADU Permits in Edmonds"
Permitting is one of the most common reasons homeowners delay or abandon ADU projects. Edmonds has specific zoning requirements, setback rules, utility connection standards, and building codes that must be followed. MacCoy Home Solutions manages the entire permit process on your behalf — submitting applications, coordinating with the City of Edmonds, and ensuring your project meets all applicable codes so there are no surprises at inspection.
"We Want to Age in Place in a Smaller Space"
For retirees and empty nesters, an ADU can serve as a smart downsizing solution — moving into a newly built, single-level cottage on your own property while renting out or hosting family in the main home. It is a way to stay in the Edmonds community you love while reducing maintenance, lowering living expenses, and staying close to the people who matter most. MacCoy specializes in comfortable, thoughtfully designed ADUs built for long-term living.
How Our ADU & DADU Design-Build Process Works
MacCoy Home Solutions manages every stage of your ADU project under one roof. Here is what the process looks like from first call to final walkthrough.
Step 1: ADU Feasibility Review
We start by listening. In your free estimate, we learn about your goals, your budget, your timeline, and what you want your new space to accomplish — whether that is housing family, generating rental income, or creating a private retreat.
Step 2: Property Evaluation & Feasibility
We review your lot size, existing structures, and local zoning requirements to confirm what is buildable on your Edmonds property. We identify setback requirements, utility connection points, and any site-specific constraints early so there are no surprises later.
Step 3: Custom Design & Planning
Our design team develops architectural plans tailored to your property and your needs. We optimize the layout for livability, natural light, privacy, and functionality — and present options for your review before anything is finalized.
Step 4: Permitting & Approvals
We submit all required ADU permit applications to the City of Edmonds — including owner-occupancy declarations, utility connection permits for the secondary unit, and setback variance requests where needed. We handle all departmental correspondence and ensure your ADU meets Washington State building code and Edmonds zoning requirements before construction begins.
Step 5: Construction & Project Management
Our experienced craftsmen build your ADU with careful attention to how the new unit integrates with your existing home — sequencing electrical subpanel installation, plumbing connections, and exterior access to minimize disruption to your daily life. Regular BuilderTrend updates keep you informed at every phase, even when you are not on-site.
Step 6: Final Walkthrough & Warranty
Before we hand over the keys, we conduct a thorough quality inspection with you. MacCoy Home Solutions backs every project with a 12-month workmanship warranty, so you can move into your new space with complete confidence.
What Edmonds ADU Clients Are Saying
Do not take our word for it. Here is what local homeowners have shared about their experience working with MacCoy Home Solutions.
Aaron and his team were highly organized, patient, and understanding throughout the process. The project required removal of walls, including a large load-bearing wall, complex relocation of plumbing and electrical, and installation of new windows, siding, cabinets, flooring, two islands, and appliances. The results are truly outstanding. The quality, the fit-and-finish, the attention to detail — the results exceed our already-high expectations. I told Aaron at the outset that our goal for the project was a forever house. The MacCoy team gave us that house.

We hired MacCoy Home Solutions for a kitchen remodel and deck project, and the experience was nothing short of exceptional. From the initial consultation to the final walkthrough, the team was punctual, communicative, and incredibly skilled. They listened carefully to our ideas, offered thoughtful suggestions, and executed everything with precision and care. The project was completed on time and within a budget we could afford, and the quality of the workmanship truly exceeded our expectations.

Their commitment to quality and excellence in their work and communication is unmatched. They won the local BBB Torch Award for Ethics and were named an international Torch Awards finalist. They recently coordinated $50,000 worth of donated home repair services to a local senior Navy Veteran who was taken advantage of by dishonest contractors. The MacCoy team truly believes in what they do and it is clear their business is rooted in a greater purpose than simply padding a bottom line.

Local Insight: Building ADUs in Edmonds, WA
Edmonds is one of the most sought-after communities on the Puget Sound, and the local housing market reflects that. With median home prices significantly above the national average and limited new construction, many homeowners are turning to ADUs as a practical way to expand housing options without leaving the city.
A large share of Edmonds homes were built between 1950 and 1990 on lots that were generously sized by the standards of the day — many with underused backyard space that is ideal for a detached ADU. Neighborhoods like Edmonds Bowl, Perrinville, and the Five Corners area are seeing growing interest in ADU and DADU construction as homeowners look to maximize their properties.
The City of Edmonds has updated its zoning code to allow ADUs on most residential lots, though specific rules about size, setbacks, and utility connections vary by property. MacCoy stays current on all City of Edmonds regulations and Washington State energy efficiency standards to make sure every project is fully compliant and built to last.
