Eighteen apartment buildings finished in Seattle in the first half of 2026. Together they add up to 1,089 units. The ones with a story count on the record run from three to eight stories, and they are spread from Northgate down to West Seattle rather than clustered in one part of the city.
This post lists those buildings by the month they opened, then covers the larger buildings under construction now, which is where the next openings come from. Every address and every unit count below comes from a permit record that BuildVue tracks.
How we decide a building has opened
A project can have a construction label in the permit system long after the work is done, and it can have one long before anyone moves in. The permit dates are what we go by. A building counts as open once its record shows a certificate of occupancy date or a final inspection date, because those are the days the city signed off and people could move in. A building appears here in the month the city closed out its permit.
Only development projects appear on this list. Single family houses and remodels are not counted.

The neighborhood in each row comes from that project's own page, which is sometimes more precise than the wider area a building gets grouped into.
Our monthly records cover January, February, March, May, and June, so this table does not include April.
Our January record puts that month's total at 351 units, one more than the three January buildings above add up to. The table uses 350, the figure we can attach to named buildings.
The largest building of the year so far is 14343 15th Ave NE in Northgate, an eight story building with 243 units that opened in January. Behind it, 1314 E Union St opened in June with 139 units on First Hill, and 12059 Lake City Way NE opened the same month with 120 units on the Lake City Way corridor.
Where the new units landed
Queen Anne had the most openings with four buildings, though three of them are small and the four together come to 94 units. Fremont had three openings totaling 118 units, almost all of that in the 95 unit building at 4905 Aurora Ave N. The International District had two openings worth 123 units.
The unit counts rank differently. One Northgate building delivered 243 units, more than any neighborhood added across multiple sites. First Hill and Lake City each got over 100 units from a single building. Across the whole list, a few large buildings account for most of the housing while the smaller four story infill projects add five to thirty units at a time.
None of these buildings started this year. A mid rise apartment building takes about two to three years from the start of construction to leasing, so the ones that opened in June pulled their construction permits well before 2026.
