Edgemoor runs along the bluff above the bay toward Chuckanut Drive, and the lots here are some of the largest in the city. That space changes what is possible. Where a tight downtown lot might only fit a garage conversion, an Edgemoor property usually has room for a true detached cottage set well back from the main house, with its own water, sewer, and power run out to it. For families thinking about a parent moving in, the same space supports a high-end attached in-law suite with its own entrance.
On premium ground like this, the work is about doing it to the standard the property deserves. A detached cottage out here needs proper utility runs trenched to it, a foundation set for the wet, wooded soil, and stormwater handled so water drains away from the unit and the bluff. We grade and manage the drainage, build to current energy code, and finish to a level that fits the neighborhood. It all starts with a free feasibility check against your lot, the setbacks, and the slope.
ADU costs in Edgemoor depend on the type. A ground-up detached backyard cottage runs $250,000 to $400,000 or more, a garage conversion runs $80,000 to $150,000, and a basement apartment conversion runs $90,000 to $180,000. The drivers are size, finish level, site access, and how far we run utilities to the unit. We give you a line-item number after a free site visit, so you know exactly what your project costs before you commit.
Do you build ADUs in Edgemoor?
Yes. Edgemoor is one of our core service areas, and we build backyard cottages, garage conversions, in-law suites, and basement apartments here. We start every project with a free feasibility check against your lot size, setbacks, and the City of Bellingham rules, so you know what your lot allows before you spend anything on design.
Who handles the permit for an ADU in Edgemoor?
We do, start to finish. Edgemoor is inside Bellingham city limits, so your ADU and its utility connections run through the City of Bellingham. We handle the permit and the site work. We assemble the full permit package, manage the review including answering reviewer comments, and carry it through to an approved permit, then handle the inspections during the build.
