98230 covers Blaine and Birch Bay — the border town on Drayton Harbor and the beach community around the warm, shallow bay. It is the county’s second-home and retirement coastline, and increasingly a first-home value play for buyers priced out of Bellingham.

What lives inside 98230

• Blaine — the harbor town at the Peace Arch crossing, Semiahmoo across the spit
• Birch Bay — beach cottages, newer resort-side plats, and the state park shoreline
• Semiahmoo — the resort peninsula’s golf-and-water addresses

Housing character + price reality

The range runs from classic beach cottages and manufactured-home parks to Semiahmoo’s gated fairway homes — with saltwater-view streets priced well under what the same view costs in Bellingham. The trades: a 30-minute run to Bellingham’s hospitals and big-box, seasonal rhythms in the beach zones, and border-town texture that some buyers love and some do not. Current medians live on the Blaine and Birch Bay guides.

Second home or first home?

Both, genuinely. Retirees and Vancouver-side families have bought here for decades; remote workers have discovered the same math. If it is a rental or second home, we talk insurance, seasonal demand, and the county’s short-term-rental rules before you write.

FAQ

Is Birch Bay a good investment? As a lifestyle purchase with rental upside, it has worked well for many of my clients; as a pure appreciation play it is cyclical. Buy the property you would be happy holding through a slow summer.

Which ZIP is my address actually in? ZIP lines cut through neighborhoods and even streets — the post office drew them for mail routes, not for real estate. Text me any address — (360) 389-6616 — and I will confirm the ZIP, the school assignment, and the neighborhood in one reply.

How close is the border, really? Peace Arch is in Blaine itself — minutes from anywhere in 98230. For cross-border families this is the most convenient ZIP in America’s corner.

What should I know about waterfront here? Much of it is bank or view rather than private tideland, and the bay is shallow — gorgeous for walking, modest for moorage. The waterfront guide explains the tideland questions.
