Conditions at a Glance
Climate figures: NOAA 1991–2020 normals from the Seattle Sand Pt Wsfo, WA station, about 7 miles away.
Conditions for Events
DOE's Building America map puts King County in the Marine climate region (IECC 2021 zone 4C, PNNL county guide). This region has mild temperatures most of the year but long damp seasons, so wet ground is usually a bigger issue than heat or cold.
Occasional Freezes
Only about 25 nights a year reach 32°F (fewer than three in four U.S. places in our data), but one hard freeze is enough to damage anything that holds water. A winter event can still land on one of the few freezing nights; ask about it if your date is in winter.
Outdoor Season
Temperatures rarely get in the way of outdoor events here, so most dates are workable.
Local Settings
For a party at an apartment complex or a rented home, the property manager or landlord decides where units can stand. For beach and waterfront events, units stand at the edge of the sand on firm ground the service truck can reach.
How Many Units
The Portable Sanitation Association International (PSAI) chart sizes event restrooms by crowd and hours, assuming no servicing during the event:
| Crowd | 1 hr | 2 hrs | 3 hrs | 4 hrs | 5 hrs | 6 hrs | 7 hrs | 8 hrs |
|---|---|---|---|---|---|---|---|---|
| 500 | 2 | 4 | 4 | 5 | 6 | 7 | 9 | 9 |
| 1,000 | 4 | 6 | 8 | 8 | 9 | 9 | 11 | 12 |
| 2,000 | 5 | 6 | 9 | 12 | 14 | 16 | 18 | 20 |
| 5,000 | 12 | 15 | 20 | 25 | 31 | 38 | 44 | 50 |
| 10,000 | 15 | 25 | 38 | 50 | 63 | 75 | 88 | 100 |
For a long community event, take 500 people over eight hours: the chart gives 9 units. If alcohol is served, PSAI adds 10–20%, which is 10 to 11 units after rounding up. For accessibility, 5% of 11 is 0.55, which rounds up to 1 ADA unit in a single cluster; split into 2 clusters of 6 and 5, each cluster needs its own, so 2 ADA units in total.
See the PSAI event chart for the full table.
Placement and Access
Put restroom rows on firm, level ground the service truck can reach, away from food prep, with ADA units on an accessible route and hand-wash stations beside the rows.
Near the Shoreline
Seattle's Census reference point is less than a mile from the shoreline in the Census Bureau's TIGER coastline layer (the layer includes Great Lakes shores and some bays). For a beach or lakefront event, place units at the edge of the sand on a surface the truck can reach, unless the provider confirms it can service them on the beach.
Who to Ask About Local Rules
Seattle is an incorporated city with its own municipal government. For a special event on public property, a park reservation, or restroom rows on a street or sidewalk, ask the Seattle city government before you book what applies.
If you rent your home, check with the landlord or property manager before a unit goes on the property. Beaches and waterfront parks can be managed by a separate parks, port or state agency; ask whoever manages that land.
What to Ask For
- Expected attendance, including staff, vendors and volunteers
- Event hours, and whether it runs over several days
- Whether alcohol or food will be served
- ADA units for every cluster (at least 5%, rounded up) and hand-wash stations
- Firm ground for rows after rain

Only where the provider can service them and the land manager allows it; most stand at the edge of the sand on firm ground.
