Expert ADU Builder in Bothell: Maximize Your Property
Building an ADU in Bothell is a smart move when the main goal is rental income, multi-generational living, or flexible space that works harder than the backyard does now. But this city is not a plug-and-play market. Bothell sits across both King and Snohomish counties, and site constraints matter fast — streams, wetlands, steep slopes, drainage, access, and setbacks can all change the build before pricing is stable.

How It Works
Our Process
Site Assessment
We review lot size, setbacks, slope, utilities, and zoning in Bothell to see whether the property fits an attached ADU or conversion.
Custom Design
Then we create a layout that matches the main house, solves access cleanly, and makes the new unit feel planned instead of squeezed in later.
Permitting
We handle Bothell permit submittals, coordinate plan requirements, and address extra review when the site touches wetlands, streams, or steep slope conditions.
Construction
From foundation through framing, utilities, insulation, and finishes, our crew builds the ADU with tight sequencing and clean jobsite control.
Turnkey Delivery
After inspections pass, we complete the final details and hand over a finished ADU ready for family use, guests, or rental income.

About Us
Bothell's Leading Custom ADU Builders
Maksymov Brownstone LLC brings 17+ years of hands-on building experience to ADU work, and that matters more in Bothell than it does in easier markets. A lot can look buildable until the survey, drainage path, or utility run says otherwise.
The city's current ADU standards allow units up to 1,200 square feet, with some conversions of existing space going beyond that when approved. We are a licensed and bonded team that handles detached cottages, attached ADUs, garage conversions, and basement conversions with the same field-first approach.
FAQ
Frequently Asked Questions About ADU Remodeling in Bothell
Planning an ADU project in Bothell 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 Bothell property.
How much does it cost to build an ADU?
The cost depends on size, utility connections, site work, and finish level. A detached backyard build usually costs more than a garage conversion in Bothell or a basement conversion because the structure, foundation, and utility work are heavier. We build estimates from the real lot, not from online averages.
Can I build an ADU on my specific lot?
Maybe — but we do not guess from parcel photos. We check setbacks, utility routing, access, drainage, and whether the site has slope or environmental constraints. In Bothell, that matters early. Some lots are best for a detached unit. Others make more sense as garage or basement conversions.
Why choose our company as your ADU builder?
Because design, permit work, and field construction need to agree with each other. That is where projects usually break. We keep the process under one roof, from feasibility through final inspection, so communication stays tight and the finished unit fits the property, code requirements, and budget better.
