Conditions at a Glance
Climate figures: NOAA 1991–2020 normals from the Houston Hobby Ap, TX station, about 12 miles away.
Ground and Route Conditions
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.
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. Rain is the main threat to an accessible route: grass and bare soil soften, and a route that was firm at setup can rut by evening. Use pavement or compacted gravel for the route where possible.
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. An accessible unit heats up in the sun like any plastic unit; put it in shade where the accessible route allows, next to the main restroom row rather than off on its own.
How Many Accessible Units
The U.S. Access Board's guide to the ADA Standards says that where portable toilets are clustered, at least 5% of the units in each cluster must be accessible, rounding up:
| Units in the cluster | Accessible units (minimum) |
|---|---|
| 1 to 20 | 1 |
| 21 to 40 | 2 |
| 41 to 60 | 3 |
| 61 to 80 | 4 |
Worked example: the PSAI chart gives 100 units for 10,000 people over 8 hours. In one cluster, 5% of 100 is 5.00, which rounds up to 5. Split into 4 clusters of 25, and each cluster needs its own: 8 ADA units in total (so splitting raises the count, because the 5% applies per cluster).
See ADA unit counts for more cluster sizes.
Placement
An accessible route has to reach the unit: firm, level ground such as pavement or compacted surfaces rather than deep grass or loose gravel, with a compliant ramp at any level change. Keep the accessible unit next to the main restroom row rather than off on its own. The Access Board's guide exempts portable units on construction sites that are used only by construction workers; units there for visitors or the public are not covered by that exemption.
Who to Ask About Local Rules
Houston is an incorporated city with its own municipal government. For a public event on public land, including where the accessible units and their route will go, ask the Houston city government before you book what applies.
What to Ask For
- How many units are in each cluster (at least 5% accessible, rounded up)
- The surface between the path and the door
- A ramp for any level change
- Placement next to the main restroom row
- A shaded spot on the accessible route
- A firm surface for the route if the ground is soft
