MNBE designs, permits, and builds ADUs, DADUs, and custom homes across Redmond, one licensed team from first site visit to final inspection.
One licensed, bonded team for the whole job, from design and Redmond Development Services Center permitting to fixed price construction.
Where an Education Hill or North Redmond lot's land value justifies it, we replace an aging home with a ground up custom home, with feasibility run honestly first.

We've taken ADU plans through Redmond's Development Services Center, the one stop counter on the 2nd floor of City Hall, where Planning, Building, Civil, and Fire run under a single coordinated review, so we know which comments their reviewers actually send back and design to them before we submit. Redmond's smaller queue and coordinated civil process reward a clean first submittal. Every submittal and every response is handled by us, never a third party expediter.
Education Hill and North Redmond climb elevated ground with views west toward the Sammamish Valley, the Idylwood lots above Lake Sammamish carry a 35 foot shoreline setback and Shoreline Master Program review, and the valley floor sits in a Critical Aquifer Recharge Area where dewatering rules can rule out a basement. We coordinate the geotechnical report early, design foundations and drainage to the site, and run critical area, shoreline, or Bear Creek and Evans Creek buffer review in parallel with the building permit instead of letting it stall the project.
Our detached ADU here in Redmond, full framing, roofing, kitchen, siding, and HVAC, finished and passed every inspection. We build the same way across the city, from Education Hill to Idylwood. See the full project, and the homeowner's verified five star review, on the project page.
What We Build in Redmond
A freestanding backyard cottage with its own entrance and address, the strongest rental performer. Redmond allows detached ADUs up to 1,000 square feet, or 40 percent of the combined house and ADU floor area, whichever is less, and the larger single family lots of Education Hill and North Redmond take one comfortably. On the Sammamish Valley floor we design to the aquifer recharge and dewatering limits, so foundations are stem wall or slab rather than deep basements.
Connected to the main house by a shared wall or addition. Redmond now allows two ADUs or tiny homes per residential lot in any combination, attached, detached, or a mix, with no owner occupancy requirement, and the transit exemption near the Downtown, Marymoor Village, and Overlake light rail stations often drops the parking requirement entirely. Often the faster permit on a tighter infill lot.
The 1970s and 80s two story and split level homes of Education Hill, Grass Lawn, and North Redmond often sit on full daylight or walkout basements, many already finished with bedrooms, a bath, and office space, that convert beautifully into legal dwellings with a separate entrance, full kitchen, and code compliant egress. Where critical area or dewatering limits block a new detached foundation, a conversion is the lowest friction path within the two ADU allowance.
On many Redmond lots, especially the established large lot streets of Education Hill and North Redmond, land value justifies replacing an aging home outright. We run that feasibility honestly, sometimes the right answer is a ground up custom home, not a remodel, and build it under the same license and fixed price contract.

FAQ
Answering the questions Redmond homeowners ask us most about building an ADU.
Yes. Under Redmond's updated zoning code (RZC 21.04.1110) and Washington's HB 1337, most residential lots allow up to two ADUs or tiny homes, in any combination of attached and detached, with no owner occupancy requirement. Redmond's consolidated Neighborhood Residential zone goes further, allowing up to six units by right per lot. We confirm the exact mix your parcel supports before design.
Initial residential review in Redmond commonly lands around three to four weeks, with intake and assignment taking a few days, quicker resubmittals, and an expedited option available. Redmond's Development Services Center runs Planning, Building, Civil, and Fire under one coordinated review and generally beats Seattle SDCI. Critical areas, shoreline, aquifer recharge dewatering, and geotech on sloped or waterfront lots drive the schedule.
Cost is site specific in Redmond, so we don't quote a generic per square foot number. A flat Grass Lawn infill lot, an Education Hill daylight basement conversion, a valley floor build facing aquifer recharge dewatering, and an Idylwood waterfront lot with shoreline review all carry different foundation, drainage, and permitting costs. After a free site visit you get one fixed price.
Thank you for considering MNBE for your Redmond ADU or custom home. We respond within one business day, Monday through Saturday.
We design and build across Redmond, from the flat infill lots of Grass Lawn and the low lying Sammamish Valley floor to the elevated, view streets of Education Hill and North Redmond and the sloping waterfront lots of Idylwood above Lake Sammamish. We handle the harder parcels too, the Bear Creek and Evans Creek corridors with their wetland buffers, and the valley sites where aquifer recharge and dewatering rules shape the foundation. Wherever your lot sits, the same team designs it, permits it through the Development Services Center, and builds it.
