Conditions for Events

DOE's Building America map puts Contra Costa County in the Hot-Dry climate region (IECC 2021 zone 3B, PNNL county guide). This region combines hot summers with low humidity: sun, dust and water supply are the usual planning issues, more than rain.

Summer Hot Spells

About 51 days a year reach 90°F, more than most U.S. places in our data; hot spells come and go rather than lasting all summer. If the date falls in a hot spell, add a hand-wash station at each row and ask about an extra service visit.

Occasional Freezes

Only about 9 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

Most of the year suits outdoor events; a summer hot spell or a rare winter freeze are the exceptions to plan around.

Local Settings

For a party at an apartment complex or a rented home, the property manager or landlord decides where units can stand.

How Many Units

The Portable Sanitation Association International (PSAI) chart sizes event restrooms by crowd and hours, assuming no servicing during the event:

Portable restroom units by average crowd size and hours (PSAI chart)
Crowd1 hr2 hrs3 hrs4 hrs5 hrs6 hrs7 hrs8 hrs
50024456799
1,0004688991112
2,0005691214161820
5,0001215202531384450
10,00015253850637588100

For a full-day festival, take 5,000 people over six hours: the chart gives 38 units. If alcohol is served, PSAI adds 10–20%, which is 42 to 46 units after rounding up. For accessibility, 5% of 46 is 2.30, which rounds up to 3 ADA units in a single cluster; split into 2 clusters of 23, each cluster needs its own, so 4 ADA units in total.

Ask about servicing during an all-day event. 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.

Who to Ask About Local Rules

Concord 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 Concord city government before you book what applies.

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
