Public restroom code
Definition
A 4–6 digit numeric or letter combination required to unlock the restroom door at some splash pads, typically posted on the entrance sign and rotated seasonally to discourage non-park use.
Restroom codes are common at urban splash pads where parks departments have struggled with vandalism, drug use, or unhoused-population sheltering in unsupervised public bathrooms. The code is usually printed on the splash pad's posted rules sign and is changed monthly or seasonally.
Families arriving early may find the code missing or peeled off — the parks department customer-service line on the sign can text the code on request. Apps like Flush and the city parks app sometimes list the current code.
