Expert ADU Builder in Burien: Maximize Your Property
An ADU in Burien is a smart way to add income, create room for family, or turn underused square footage into housing that actually works. The city now allows up to two ADUs per lot, which gives owners more flexibility than they had a few years ago. But Burien ADU requirements still need to be handled carefully. Size caps, tree retention, utility tie-ins, and site limits can move the plan fast. On some lots, sensitive areas or shoreline rules also affect the permit path.

Building an ADU in Burien can feel overwhelming
Planning an ADU in Burien comes with its own set of challenges — zoning rules, permits and tight budgets. Many homeowners feel uncertain about where to begin. With experienced accessory dwelling unit builders who know Burien, the path forward becomes much clearer.
Where Do I Even Start?
The Burien ADU process — design, city approvals, construction — can feel impossibly complex for first-time builders.
Hidden Costs
Unexpected fees and vague quotes leave homeowners over budget before construction even begins.
Delays & Unreliable Contractors
Missed deadlines and poor coordination drag projects on for years — costing time and money.
Lack of Clear Communication
Homeowners are often left in the dark, unsure of progress or next steps on their project.
Burien ADU builders committed to quality craftsmanship and clear communication.
How It Works
Our Process
Site Assessment
We review lot size, setbacks, utilities, trees, and site limits first, because in Burien the property usually decides the smartest ADU path.
Custom Design
Then we build a layout that fits the main house, solves circulation cleanly, and makes the new unit feel intentional instead of forced.
Permitting
We prepare the permit package and coordinate local review, including added requirements if the site falls in a critical area or shoreline jurisdiction.
Construction
From foundation through framing, insulation, utility tie-ins, and finishes, our crew builds the ADU in a tight sequence with close field control.
Turnkey Delivery
After inspections pass, we complete the final details and hand over a finished ADU ready for family use, guests, or long-term rental.

About Us
Burien's Leading Custom ADU Builders
Maksymov Brownstone LLC brings 17+ years of hands-on construction experience to ADU work, and Burien is the kind of city where that experience saves real money. A lot can look easy until the permit set pulls in tree protection, utility coordination, fire access review, or shoreline limits.
Burien's current rules allow two ADUs per lot and generally cap internal, attached, and detached ADUs at 1,000 square feet, though the city can allow exceptions to better use existing spaces in buildings that are at least five years old. We are a licensed and bonded team that works through those realities early.

Why an ADU Is a Smart Investment in Burien
Rental Income
In Burien, a well-built ADU can generate $1,800–$3,200 per month. This consistent income helps offset the initial build cost, making your project financially sound over time.
Increase Property Value

FAQ
Frequently Asked Questions About ADU Remodeling in Burien
Planning an ADU project in Burien comes with many questions about permits, timelines and budget. Below we cover the most common concerns homeowners have. Feel free to reach out for a personalized consultation and clear guidance specific to your Burien property.
How much does it cost to build an ADU?
The cost depends on size, site work, utility connections, and finish level. A detached build usually costs more than a garage or basement conversion because the structure, foundation, and exterior work are heavier. In Burien, tree retention, utility certificates, and fire access review can also move the number. We price from the real property, not online averages.
What are the main Burien ADU requirements?
The big ones are unit size, zoning compliance, and utility approval. Burien allows up to two ADUs per lot, and internal, attached, and detached ADUs are generally limited to 1,000 square feet. Detached ADUs can also trigger separate sewer connection requirements, while water review and fire access checks are part of the permit path.
Can I build an ADU on my specific lot?
Maybe, but we do not guess. We check setbacks, lot layout, utility access, tree limits, and whether the property is affected by critical areas or shoreline jurisdiction. On some Burien sites, those issues matter more than the lot size on paper. A clean site review saves far more than it costs.
Why choose our company as your ADU builder?
Because ADU jobs usually break at the handoff points. Design says one thing, permitting says another, and the field has to absorb the mistake. We keep the work under one roof from feasibility through final delivery. That cuts miscommunication, protects the budget, and gives you a cleaner result.
