Maksymov Brownstone LLC

Bellevue Wa DADU Builder

A DADU can look simple until Bellevue site limits show up: tree roots, utility easements, stormwater flow, rear setbacks, garage access. Miss one, and a backyard cottage turns into redesign.

Maksymov Brownstone LLC handles Bellevue WA DADU construction for homeowners planning family space, rental income, or a private unit near Downtown Bellevue, Crossroads, Lake Hills, or Somerset. As a Bellevue DADU contractor, we check drainage, access, fire separation, electrical service, parking, and daily entry routes early. The goal is practical: build around the lot, not against it.

Why build a DADU in Bellevue?

Bellevue lots carry real value, and a DADU can turn unused backyard space into family housing, a long-term rental, guest quarters, or a downsized home. Unlike a basement ADU or garage conversion, a detached unit gives the second household its own entry, kitchen, bath, walls, roof, and privacy.

Maksymov Brownstone LLC works as a Bellevue DADU builder with permit-ready planning, usable layouts, and clean construction built for daily life in 600 to 1,200 square feet.

Dadu building

Tailored backyard units for local homes

A DADU is a detached accessory dwelling unit on the same property as the main home. It adds privacy, but also requires careful planning: foundation, utilities, sewer, grading, access, roof drainage, and inspections.

Most problems start before framing, when slope, property lines, or material access get missed. Our team checks Bellevue site constraints early, so the design fits the lot, city review, and real daily use.

Custom planning for Bellevue properties

A customized DADU Bellevue WA project should start with the property, not a stock plan. A flat Lake Hills lot, a sloped Somerset site, and a narrow Wilburton backyard all need different solutions.

We plan around setbacks, trees, drainage, utility routes, buildable area, and the main house relationship first. Then the layout can support rental storage, parent-suite access, guest comfort, light, ventilation, and a kitchen that feels intentional.

Design-build from one team

With DADU design-build Bellevue WA services, the same team carries the project from early planning through construction. That matters because the person drawing the wall assembly should understand what happens when rain hits the siding, where the vent line runs, and how inspections affect the schedule.

Design-build also cuts down on blame-shifting. The plan, permit package, materials, subcontractor coordination, and jobsite work stay connected.

When a detail needs adjustment, we solve it before it turns into three weeks of emails.

Our process covers site review, concept planning, construction drawings, permit coordination, foundation work, framing, utilities, insulation, drywall, finishes, and final walkthrough. No mystery handoff in the middle.

DADU construction roadmap

MB Remodels follows a structured Bellevue DADU construction workflow to keep each project organized, on budget, and built to a high standard with clear communication at every stage.

Schedule consultation
  • 01

    Site walk & planning

    We start with the Bellevue lot: access, grade, trees, drainage, utilities, existing structures, and how the DADU sits beside the main home. This early review sets the scope, budget range, and construction approach before drawings go too far.

  • 02

    Design stage

    Field conditions become a buildable DADU plan: layout, exterior form, windows, storage, mechanicals, and finishes. We keep compact spaces efficient, avoid wasted hallways, and solve awkward window or bathroom placement while changes are still easy.

  • 03

    Bellevue DADU permitting services

    Our Bellevue DADU permitting services organize drawings, zoning checks, required documents, and review responses. Setbacks, lot coverage, easements, critical areas, utilities, and fire separation are handled early so approval does not turn into a construction delay.

  • 04

    Construction & completion

    After permits, we sequence site prep, foundation, framing, roofing, utilities, inspections, insulation, drywall, cabinets, tile, paint, trim, and fixtures. Details like flashing, subfloor prep, and tile support are treated as structural quality, not decoration.

Built for the lot. Planned for the permit. Finished for daily living.
We do more than DADU construction

We do more than DADU construction

Maksymov Brownstone LLC supports Bellevue homeowners with remodeling work that often connects to a DADU project: basement remodels, garage conversions, attic upgrades, kitchens, bathrooms, custom cabinetry, and interior finishes. This helps when the main house and backyard unit need to function together. One team can plan storage, access, finishes, and sequencing without creating conflicts between separate projects.

We had a great experience with our living room remodel. We needed to remove a large built-in cabinet and fireplace; replacing it with a new fireplace, surround, shelves, and repairing the walls and flooring. Ihor and the team were very communicative, easy to work with, and they treated our time and home with respect. They stayed engaged even through the final finishing touches. We are thrilled with the result and would recommend their work. Before and after pictures added.

Frequently asked questions

This section covers the most common questions that clients ask about DADU construction services. If you have any additional questions, contact our support team for more information.

How much does it cost to build a DADU in Bellevue?

Cost depends on size, site conditions, design complexity, utility work, access, foundation type, and finish level. A small backyard cottage on a flat lot is not the same project as a two-bedroom DADU on a slope with longer utility runs. We price after reviewing the lot and scope. Guesswork feels easy at the start, then gets expensive.

How long does Bellevue DADU construction take?

The timeline depends on design, permitting, site work, inspections, and material selections. Straightforward builds move faster. Sloped lots, utility upgrades, critical areas, or major plan revisions add time. Maksymov Brownstone LLC maps the project in stages so the homeowner knows what is happening before construction starts.

Do I need permits for a DADU in Bellevue WA?

Yes. A detached dwelling unit needs proper review and approval before construction. The permit package typically involves drawings, site planning, zoning review, structural details, utility coordination, and code compliance. Our Bellevue DADU permitting services help organize that process and reduce back-and-forth with missing information.

How large can a Bellevue DADU be?

Bellevue rules and program limits should always be checked for the specific property. Lot size, setbacks, height, coverage, easements, and overlays can all affect what is possible. A design that works on one Bellevue property may not work next door. We verify the constraints before committing to the layout.

Can a Bellevue DADU be used as a rental?

In many cases, a DADU can be used as a rental when it meets applicable building, safety, zoning, and utility requirements. The unit must be planned as a real dwelling, not a dressed-up shed with plumbing. That difference matters.

What makes a good Bellevue DADU builder?

A good Bellevue WA DADU builder understands both construction and permitting. Pretty drawings are not enough. The builder has to know how water moves across the lot, how inspections affect sequencing, how tight access changes labor, and which details will cause problems after move-in. That is the work behind the work.

Can you design and build the entire DADU?

Yes. Maksymov Brownstone LLC provides design-build support for Bellevue DADU projects, from early planning and permit coordination to construction and finishing. One team stays involved through the whole process, so the design does not get disconnected from the build.

What is the first step?

The first step is a property review. We look at the lot, access, existing structures, utilities, slope, trees, and homeowner goals. After that, we can discuss layout options, permitting path, budget range, and schedule. Start there. Everything else depends on the site.
