Generally Investor friendly
Allowed under state law and broadly supportive of ADU development with clear standards and minimal parking burdens, but HB 1337’s “owner‑occupancy” exception likely restricts STRs to owner‑occupied ADUs, adding a meaningful compliance step; local STR licensing, fees, caps, and enforcement are not specified, leaving some procedural uncertainty but no outright prohibitions or heavy caps.

Mercer Island is a suburban city of roughly 25,000 residents set on a forested island in the middle of Lake Washington, within King County in western Washington state. The community is known for its quiet, residential character, tree-lined streets, and waterfront homes, while functioning as a convenient in-between for two of the region's largest urban centers. It sits about five miles east of downtown Seattle, with Bellevue and the Eastside tech corridor just across the floating sections of Interstate 90 to the east, making the island a peaceful base for travelers who want easy access to the wider Puget Sound region.
One of the island's most beloved green spaces is Luther Burbank Park, a roughly 77-acre waterfront park on the north end of Mercer Island. It offers public beach access, swimming areas, walking paths through old-growth forest, and views back across Lake Washington toward Seattle's skyline. Because the park sits at the island's edge, it is only a short drive from almost anywhere on Mercer Island, often under ten minutes.
Just across the I-90 bridge to the west, Seward Park in Seattle wraps around a peninsula jutting into Lake Washington. The park contains old-growth cedar forest, paved and unpaved trails, kayak rentals, and a swimming beach, drawing both locals and visitors. From central Mercer Island, the drive to Seward Park typically takes about 15 minutes, depending on traffic crossing the bridge.
A short drive east on I-90 places visitors in downtown Bellevue, the largest city on Seattle's Eastside. Bellevue has grown into a destination in its own right, with the green spaces of Bellevue Downtown Park, the Bellevue Arts Museum, the Bellevue Collection shopping center, and a thriving restaurant scene. The trip from Mercer Island to downtown Bellevue generally takes about 10 to 15 minutes, making it an easy evening out for island-based visitors.
For those willing to venture farther, Lake Washington itself, the second-largest natural lake in the state, frames the island on all sides. Public beaches, kayaking routes, and sailing opportunities line its shores, while the Mountains-to-Sound Greenway begins just east of the island and offers hiking and outdoor recreation within roughly an hour's drive toward the Cascade Range.
Mercer Island's appeal as a short-term-rental base comes from its unusual combination of calm suburban atmosphere and central location. Guests can stay in a quiet lakeside neighborhood while remaining within easy reach of Seattle's cultural attractions, Bellevue's shopping and dining, and the outdoor playgrounds of the Cascades, all connected by the I-90 corridor that runs directly through the island.
