The median home sale price in Capitol Hill, Seattle, WA sits around $792,199 – and with homes spending a median of just 21 days on the market, those buying a home in Capitol Hill don’t have the luxury of being vague about where they want to be. Knowing the exact postal boundaries isn’t a technicality; it’s how you avoid falling in love with a listing that turns out to be in a completely different part of Seattle.
Capitol Hill spans multiple zip codes, each covering distinct sections of the neighborhood – from historic parks to the main commercial corridors. What looks like one cohesive area on a map is actually three overlapping postal zones, and the differences between them matter when you’re evaluating price, housing type, and what you’ll be walking out your front door to find.
Primary Postal Codes Serving Capitol Hill
Capitol Hill doesn’t have a single dedicated postal boundary, which trips up a lot of buyers who assume they can just filter by zip code and call it a day. The neighborhood primarily falls under 98102, which covers the dense central and northern sections.
It also extends into 98112 to the east and 98122 to the south. Because these borders blur into adjacent Seattle districts, you should check specific addresses rather than relying solely on the five-digit code to confirm a property actually sits within Capitol Hill.
The 98102 Boundary
The 98102 zip code captures the core of Capitol Hill. You’ll find a mix of older single-family homes, townhouses, and newer condominium buildings here, and the central placement within Seattle city limits tends to keep demand consistent.
Adjacent Areas in 98112 and 98122
The 98112 zip code covers the eastern edge of Capitol Hill – tree-lined streets, larger lot sizes, and a quieter feel as you move toward the neighborhood’s outer limits.
To the south, 98122 incorporates the lower portion of Capitol Hill. Buyers looking here will see a high concentration of multi-family housing and recent development.
King County and Seattle Metro Context
Capitol Hill sits entirely within King County, WA, near the center of the Seattle metropolitan area – officially designated as the Seattle-Tacoma-Bellevue metro region. All three zip codes, 98102, 98112, and 98122, fall under King County’s jurisdiction.
If you’re relocating from out of state, it’s worth verifying local county procedures, since administrative rules apply uniformly across all three boundaries. King County property records are your official source for boundary confirmation on any home you’re considering.
Neighborhood Sub-Areas by Postal Code
Capitol Hill breaks down into several distinct sub-areas, each with its own housing character and relationship to the neighborhood’s main streets. The commercial thoroughfares of Broadway and the Pike/Pine corridor run through the center, and the residential areas radiating out from there tell different stories depending on which direction you go.
Beyond the commercial core, areas like North Capitol Hill and Stevens Addition – also known as Millionaire’s Row near 14th and 15th Avenues – offer a different profile entirely. Matching your housing preferences to these specific pockets is how you avoid wasting time on listings that don’t fit what you’re actually looking for.
North Capitol Hill and Volunteer Park
North Capitol Hill centers around Volunteer Park, an Olmsted-designed space listed on the National Register of Historic Places and recognized as a Seattle city landmark. The park houses both the Volunteer Park Conservatory and the Seattle Asian Art Museum. Homes in this northern section tend to be larger, historic single-family properties, and this area falls predominantly within the 98102 zip code.
Broadway and the Pike/Pine Corridor
Broadway and the Pike/Pine corridor are the main commercial thoroughfares for Capitol Hill – high-density housing, mid-rise apartment buildings, condos, and immediate access to retail, dining, and public transportation. Buyers focused on this central and southern section will likely be searching within the 98122 zip code.
Finding Full Nine-Digit Postal Codes and Area Codes
The telephone area code for Capitol Hill is 206, covering Seattle and its immediate surrounding cities. The 564 area code also serves as an overlay for the broader Seattle area, so new phone numbers may use that prefix instead.
For utility setup and mortgage paperwork, you’ll need your full nine-digit ZIP+4 code. The United States Postal Service assigns those extra four digits to identify a specific city block, apartment building, or delivery route – it’s more granular than most buyers expect. You can find the exact ZIP+4 for any Capitol Hill property by entering the street address into the USPS online lookup tool. Title companies and lenders require the full code for official property documentation, so don’t wait until closing week to track it down.
