Lake Whatcom lots where a backyard unit can be a rental or a guest cottage, and where site and drainage planning matter on the sloped, lakeside ground.
Silver Beach runs along the north end of Lake Whatcom on the east side of Bellingham, and the lake is the whole appeal. A backyard cottage here can pull double duty, a rental that benefits from the lakeside location or a guest cottage for family who visit the water. The lots range from older 1950s cabins to newer custom homes, and many of them slope toward the lake, which is the part that takes real planning.
Sloped, lakeside ground means drainage and site work are front and center. A cottage on a poorly drained lakeside pad sits in standing water through the wet season, and being near Lake Whatcom, the city's drinking-water source, means stormwater has to be managed carefully. We grade the site so water moves away from the unit and the lake, set a foundation built for the slope, and handle the stormwater the City requires. Every Silver Beach project starts with a free feasibility check on the lot, the slope, and the setbacks, then we build to current energy code.
ADU costs in Silver Beach 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 Silver Beach?
Yes. Silver Beach 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 Silver Beach?
We do, start to finish. Silver Beach is inside Bellingham city limits, so your ADU and its stormwater work run through the City of Bellingham, with extra care near the Lake Whatcom watershed. We handle the permit. 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.
