Conditions at a Glance
Climate figures: NOAA 1991–2020 normals from the Houston Hobby Ap, TX station, about 12 miles away.
Conditions for Events
DOE's Building America map puts Harris County in the Hot-Humid climate region (IECC 2021 zone 2A, PNNL county guide). This region pairs heat with humidity for much of the year; for long rentals in the hot months, ask how often units will be serviced.
Heat
About 101 days a year reach 90°F or more, more than three in four U.S. places in our data, so heat is the normal condition for months at a time. For long rentals in the hot, humid months, ask how often units will be serviced. Long, hot event days mean more use per unit and tanks that fill sooner: plan a service visit between days of a multi-day event, keep queues short so nobody waits in the sun, and put hand-wash stations at every restroom row.
Outdoor Season
With only about 4 freezing nights a year, heat rather than cold sets the plan: the summer months are the ones that call for extra servicing and shade (see Heat above).
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:
| 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 |
On one of Houston's roughly 101 days at 90°F or more, take a five-hour event for 1,000 people: 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.
On hot days, add a service visit for anything longer and put hand-wash stations at every row. 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.
Rain and Ground
About 56 inches of precipitation falls in an average year, with about 17 days of an inch or more, in the top tenth of U.S. places in our data. Grass venues soften after heavy rain; set restroom rows on the firmest, highest ground beside a hard surface the truck can use, and keep the ADA route on pavement or another firm surface.
Who to Ask About Local Rules
Houston 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 Houston 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.
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
- Extra servicing on hot days
- Firm ground for rows after rain
