What is a gender-neutral restroom?

Four terms, precisely distinguished

Colloquially these terms are used interchangeably, but modern plumbing codes and civil-rights statutes define them with meaningful differences.

• Single-occupancy restroom. A physical configuration — one water closet (plus up to one urinal) inside a lockable room used by one person at a time. Defined in California Health & Safety Code §118600 and NYC Local Law 79 of 2016.
• All-gender restroom. The preferred regulatory term in the 2021 International Plumbing Code and California AB-1732. Signals a policy — this room is available to any person — and can apply to single- or multi-user rooms.
• Gender-neutral restroom. The civil-rights and advocacy term, used in DC's 2006 rulemaking (4 DCMR §802). Means the same thing as all-gender.
• Unisex restroom. The older code term, still used in 2010 ADA Standards §213.2.1. Increasingly deprecated in favor of "all-gender" in newer codes.

US legal context

Federal

The 2010 ADA Standards for Accessible Design §213.2.1 has required a "unisex (single-use or family)" toilet room in specific building categories — assembly, malls, transit stations — for more than 15 years. The ADA rationale explicitly cites the need for "assistance from family members or persons of the opposite sex."

OSHA's workplace guidance (Best Practices Guide, June 2015) states that employees should access restrooms matching their gender identity; employers may offer (not require) a single-occupancy gender-neutral option.

Title IX is unsettled. The 2024 Biden-era rule was vacated by a federal court on January 9, 2025, leaving 2020 regulations operative. As of March 2026, 22 states have some form of restroom-access restriction affecting transgender people — guidance in this area is administration-dependent.

States and cities with single-occupancy designation laws

Design standards that actually matter

The 2021 International Plumbing Code §403.1.1, Exception 2 is the governing standard for multi-user all-gender design. It requires:

• Total fixtures sized at 100% of the occupant load (not halved as with gender-segregated rooms)
• Water closets in fully enclosed stalls (§405.3.4)
• Urinals either in stalls or visually separated (§405.3.5)
• Shared handwashing area permitted

The Stalled! design guidelines — a collaboration between architect Joel Sanders, historian Susan Stryker, and legal scholar Terry Kogan, recognized with the AIA Innovation Award in 2018 — specify the practical features that make a multi-user all-gender restroom actually private:

• Floor-to-ceiling partitions with no gaps above or below
• Full-height doors with sight-line-blocking latches
• Interior locks on each stall
• A communal handwashing zone in open view (increases accountability, reduces cost)
• Functional zoning (grooming / washing / toileting) rather than gender zoning

Who benefits, and why

The population using gender-neutral restrooms is broader than often assumed. Evidence-based:

• Transgender and non-binary travelers. The 2015 US Transgender Survey (N=27,715) found 59% avoided public restrooms in the past year, 32% limited food and drink intake, and 8% developed a urinary-tract or kidney issue from avoidance.
• Parents with opposite-gender children who can't reasonably accompany them into a segregated restroom.
• Caregivers with opposite-gender dependents — adult children assisting aging parents, personal care assistants for people with disabilities. ADA §213.2.1 explicitly cites this scenario.
• People with ostomies, catheters, or IBD. Pouch changes and catheterization require privacy unavailable in multi-stall rooms. See our glossary entries on stoma-friendly restrooms and IBS-friendly travel.
• Disability advocates. All-gender single-occupancy rooms double as accessible family rooms, removing the need for separate negotiation.

Common misconceptions

• Myth: "All-gender restrooms increase assault or privacy-violation risk."Hasenbush, Flores & Herman (2018), Sexuality Research & Social Policy (DOI: 10.1007/s13178-018-0335-z) compared Massachusetts localities with and without trans-inclusive public-accommodations laws. They found no statistically significant change in restroom-related police reports of assault or privacy violations.
• Myth: "They cost more to build."The 2021 IPC sizes fixtures at 100% of occupant load rather than 50%/50% — in practice this reduces duplicated fixtures and square footage. ICC's technical bulletin documents cost-neutrality or savings in realistic scenarios.
• Myth: "Women will lose privacy."Floor-to-ceiling partitions with full doors (the Stalled! standard) provide more visual and acoustic privacy than the US-standard multi-stall women's room with 1-inch door gaps. European-style stalls have been the norm across much of Europe for decades.
• Myth: "Trans people pose the risk."Reverse: trans people are overwhelmingly the targets of restroom harassment, with 12% in the 2015 USTS reporting verbal harassment, physical attack, or sexual assault when accessing a restroom in the prior year.
• Myth: "It's a new, experimental concept."The 2010 ADA Standards have required unisex/family rooms in assembly, mall, and transit buildings for over 15 years. DC has mandated all-gender signage on single-occupancy restrooms since 2006.

How to find one

No federal registry exists. Practical options:

• Refuge Restrooms — founded February 2014 by Teagan Widmer as a successor to the defunct Safe2Pee database. Community-moderated, with filters for unisex, accessible, and changing table. A public API is documented at refugerestrooms.org/api/docs.
• RestMap's LGBTQ+ restroom finder — integrates Refuge data alongside AI quality scores for 2M+ locations across 8 countries. No account required; location stays on your device.
• Google and Apple Maps accessibility attributes — self-reported by businesses, not audited. Useful as a starting point.
• Campus maps at universities — many maintain authoritative all-gender restroom lists (search for "[university name] all-gender restrooms").
